NASA’s Mars rover, Opportunity, fell silent earlier this year, but even if it never regains full function, it had one last gift to give. Scientists have transformed Opportunity’s image of its 5000th sunrise on Mars into music using a process called data sonification.

“Image sonification is a really flexible technique to explore science and it can be used in several domains, from studying certain characteristics of planet surfaces and atmospheres, to analyzing weather changes or detecting volcanic eruptions,” says Domenico Vicinanza, director of the Sound and Game Engineering research group at Anglia Ruskin University. “In health science, it can provide scientists with new methods to analyze the occurrence of certain shapes and colors, which is particularly useful in image diagnostics.”

He and his co-creator, the University of Exeter’s Genevieve Williams, will debut their two-minute composition (“Mars Soundscapes”) at NASA’s booth at the Supercomputing SC18 conference this week in Dallas, Texas.

Fears for NASA’s Opportunity rover are growing after engineers lost contact with Mars’ oldest mechanical explorer during a raging dust storm.

NASA confirmed that Opportunity’s subsystems had been knocked off as the Martian storm, which is enveloping the Red Planet and blocking out the sun, continues to intensify. Solar power is essential for the rover to operate.

While the rover has proved more resilient than expected by lasting nearly 15 years despite being only designed for a 90-day mission, the end could now be nigh for the durable device.

As it stands, the rover’s mission clock which is programmed to wake the computer so it can check power levels, is the only function still operational.

Mission engineers are doubtful that the rover has enough sunlight to charge back up for at least the next several days. NASA says if the spacecraft’s computer determines that its batteries don’t have enough charge, it will again put itself back to sleep.

The massive dust storm, first detected on May 30, now blankets a quarter of the planet –  some 14 million square miles (35 million sq km) of Martian surface.

This is not Opportunity’s first time to hunker down during a dust storm, however. In 2007 a huge storm covered the planet, leading to two weeks of minimal operations, including several days with no contact from the rover in an effort to conserve its power.

Google Maps and Google Earth have unveiled two striking similarities between a site in Japan and an era of landmass on Mars.

The coincidence has even caused some to claim that aliens exist, and have something to do with the two similar shapes.

Google Mars allowed users to view the surface of the red planet, and eagle-eyed users spotted this coincidence.

Google Mars is a website like Google Earth, but users can zoom in on satellite imagery of the Martian surface.

The mound looks very similar to the Kofun Era tomb in Japan (36°07’45.6″N 139°28’53.0”E).

You can find it by searching 6° 3’57.07″N 92° 4’13.22”E on Google Mars.

Could this be proof that Martians have settled on Earth and Mars, or signs of an ancient civilisation on the faraway planet?

Although it is hard to be sure, scientists exploring Mars have released no news of extraterrestrial contact…yet.

The Kofun Era tomb in Japan is also occasionally known as the Inariyama Kofun. 

The tomb has an enormous length of 120 m. The Inariyama Sword was excavated here in 1968.

It is a large sold which has a gold inscription carved into it. 

The writing on the sword reads: “From generation unto generation, we have served as the sword-bearers’ chiefs, down to the present time.”

In July last year conspiracy theorists were sent into meltdown by Google images showing a fully-fledged space colony on the surface of Mars. 

If certain coordinates are used it shows an artificial colony of white buildings powered by solar panels.

Users can even zoom inside the buildings, showing it is a genuine artificially-built complex.

But there’s little chance of an imminent alien attack as the images are fake and were uploaded to Google Mars, by Google for an April Fools Day joke this year.

When Justice League hits theaters this weekend, one traditional member of the team will be absent: the Martian Manhunter. But fret not, Manhunter fans: Justice League producer Charles Roven is totally down for a Martian Manhunter movie. Just when that might happen, however, is anyone’s guess.

While the Martian Manhunter has appeared in the animated Justice League, and been given live-action counterparts on TV with Smallville, The Flash and Supergirl, the character has yet to make the leap to the big screen. Anyone hoping for the character, also known as J’onn J’onzz, to pop-up in a Justice League cameo is going to be disappointed – he’s not there. But he might grace the silver screen at some point.

Justice League producer Charles Roven gave a quick interview to CBR in which he revealed his desire for a potential Martian Manhunter film. When asked what “unusual property” in the DC universe Roven might want to bring to the screen, the veteran producer said:

“I wouldn’t necessarily say that I would rather do that character, because we know that there is going to be a Flash movie, we know that Aquaman is being done, I think that Cyborg deserves his own movie too, and I know that the fans are out there screaming for Green Lantern, that’s for sure. But I was always a fan of J’onn J’onzz, Manhunter from Mars.”

Martian Manhunter is a superhero from – you guessed it – Mars. Like Superman, he’s one of the last surviving members of his race. A martian holocaust took the lives of his wife and daughter, which nearly drove him mad until he ended up on earth. His powers include shape-shifting, telepathy, super-speed and flight. And he makes a mean omelette (maybe; I’m just guessing on that last one).

Of course, it’s worth noting that Roven only says he’s a fan of the character and would be perfectly happy bringing him to the DCEU universe, but he doesn’t specify that’ll be happening anytime soon. DC has their plate full at the moment: in addition to Justice League hitting theaters this week, they also have James Wan’s Aquaman scheduled for 2018, Patty Jenkins’ Wonder Woman 2, Black Adam and David F. Sandberg’s Shazam! all set for 2019, a standalone Batman movie from Matt Reeves that may or may not star Ben Affleck, Suicide Squad 2 from director Gavin O’Connor, a Flashpoint movie, a Joss Whedon-penned Batgirl film – the list goes on and on, folks. Maybe Martian Manhunter can find his place in there somewhere.

  • Andy Weir, author of “The Martian,” released a novel called “Artemis” on Tuesday.
  • In the book, tourists get to the moon by launching in spaceships from Kenya.
  • Weir thinks building a lunar spaceport in an African country isn’t as far-fetched as it sounds.
  • Kenya could circumvent out-of-date US space regulations, launch rockets with less fuel, and improve the economics of space travel.

Kenya isn’t the first country you’d think of to locate a spaceport for launching people to and from the moon, but in “Artemis“, a new sci-fi novel by “The Martian” author Andy Weir, that is precisely the case.

Weir’s tale takes place during the 2080s at Artemis — humanity’s first and only lunar city. It’s a riveting story about a high-stakes heist featuring Jasmine “Jazz” Bashara, a Saudi-born woman and witty smuggler who has lived inside the aluminum bubbles of Artemis since she was a kid.

moon colony lunar city illustration artemis sci-fi novel andy weirSamantha Lee/Business InsiderTrue to Weir’s typical style, the book is built around real-life science, engineering, and — at least this time around — economics. He says the point of doing this is to make his stories seem more real, and thus engaging and entertaining.

But if that’s the case, why skip an established space center like Cape Canaveral, Fla., and start fresh in Kenya?

“One of the biggest impediments to the commercial space industry right now isn’t technology, its policy,” Weir told Business Insider. “I’ve listened to the things that commercial space companies have said — I’ve been at SpaceX a few times — and the consistent thing that pretty much everybody says is, it is such a pain in the ass to deal with the policies. That’s always their biggest problem.”

Kenya, however, doesn’t really have such rules — which could make it the perfect place to base an enormously expensive lunar-launch facility.

Our spaceflight regulations are out of date

The disdain against spaceflight regulations is not for wont to skip safety rules, says Weir — far from it: A safe track record is one of the most valuable assets of a space business.

What he’s talking about are sometimes strange rules created in the 1950s and 1960s to satisfy the Outer Space Treaty, which curtails weaponizing spacecraft, among other concerns. But it couldn’t plan too much for the rapid advance of space technologies.

“In the US, which is kind of in the forefront of commercial space, we have a whole bunch of really antiquated rules — like 50, 60 years old,” Weir said. “And they’re really, really out-of-date.”

As an example, Weir mentioned the work of Moon Express team, which is trying to win the Google Lunar X Prize by launching a robot to the moon and beaming live video.

“They’ve gotten to the point where they can do it for about $ 300,000” by shrinking down electronics and hitching a ride in a normally unused part of a powerful rocket, Weir said.

“But one of the rules, one of the laws, is ‘Hey, if you’re gonna launch from from the US, then you have to be able to communicate on these FM frequencies … ‘so that we can monitor it and ensure that you’re not violating the treaty,” Weir said.

These days, however, many smaller, more efficient, and higher-bandwidth radio technologies exist, and Moon Express plans to use one of them to win millions of dollars.

“And so what sucks is that this ball of requirements is … they also have to have this other clunky radio that just sucks their battery dry aboard, to meet this kind of arbitrary and ludicrously out-of-date rule,” Weir said, significantly adding to their spacecraft’s size and weight. “And it’s really holding them up.”

Kenya has launch appeal

That’s why in “Artemis”, Weir routes all passengers and cargo to the moon through the fictional Kenya Space Corporation.

“So what I thought was, there are market forces at play that people haven’t tapped into yet, and reducing policy could bring a space industry to your country,” Weir said. “And so that’s what Kenya did [in my book] — Kenya said like, ‘Hey we have two things that people want: we can set policy to be as friendly as possible for a space industry, and we’re on the equator.'”

Being located as close to the equator for rocket launches is not a new idea. Author Jules Verne had the foresight in his 1865 novel “From the Earth to the Moon” to place a fictional US location for launching a bullet to the lunar surface near Cape Canaveral.

The closer one is the equator, the less fuel it takes to make it to orbit.

Photographers take pictures as the Soyuz MS-04 spacecraft carrying the crew of Jack Fischer of the U.S. and Fyodor Yurchikhin of Russia blasts off to the International Space Station (ISS) from the launchpad at the Baikonur Cosmodrome, Kazakhstan, April 20, 2017. REUTERS/Shamil ZhumatovThomson Reuters“By being on the equator, that makes launching cheaper because you get 500 meters per second of the Earth’s rotational speed for free, which is a big deal,” Weir said. “So within the story the idea is they said, ‘We’ll commandeer the land … We will tax you less than you get taxed anywhere else. You don’t have to worry about union rules, you can do whatever you want…’ Just as pro-business-friendly as they possibly could be. And within the story, that works.”

Weir said he considered other countries for placing his fictional KSC launch complex, like Brazil, but ultimately stuck with Kenya because it seemed more interesting.

“Of the African countries on the equator Kenya it is the most advanced, in terms of economics. They have the strongest economy, they have the most stable government, and so on,” Weir said. “Artemis was built about 50 years from now, so I can say, ‘Oh yeah, things got a lot more stable in Africa.'”

He added that other Cold War-era US rules also made Kenya an appealing location by not applying.

“One of the main things is that every [employee] has to be American citizens … Also, you’re not allowed to cooperate or work with China in any way, which is kind of rough if you want to do some sort of mass-production, right?” Weir said.

“It’s just this huge pain in the ass that’s set up for a world where only governments do space missions,” he said. “So it would be nice if that didn’t exist.

  • “The Martian” author Andy Weir has a new novel about a heist on the moon called “Artemis.”
  • The book, which goes on sale Tuesday, strives for a high level of scientific and economic realism to make its story believable.
  • The author used real-world economics to create a reason his fictional moon colony might exist.
  • According to Weir’s calculations, in a few decades it may cost $ 70,000 for a two-week vacation to the moon.


Editor’s note: “Artemis” is the second sci-fi novel written by Andy Weir, author of the blockbuster sci-fi novel “The Martian.” The new book goes on sale Tuesday. Just as Weir accomplished with “The Martian,” he strived for a high level of scientific realism with “Artemis.”

But his new story is not a tale of survival like the first.

Instead, “Artemis” is a fictional heist story that takes place at the moon’s first city (also called Artemis). Weir wanted to make the plot as believable as possible, so he became an “armchair economist” and drafted an in-depth financial argument for his lunar colony based on real-world market forces.

When Weir offered us a 3,000-word (and spoiler-free) treatise laying out the economics behind his fictional moon city, we couldn’t resist. Here’s why he thinks lunar vacations just might make the first permanent lunar colony a reality.

Introduction

Artemis Final Book JacketCrown PublishingAre you a pedantic little s—? Do you ask questions like “Why does the Federation have starships if they can beam people hundreds of light-years?” or “Why don’t the Galactic Empire and Rebel Alliance just mass-produce droids with piloting skills instead of risking their own lives?”

Well, good. So am I.

“Artemis” takes place in a city on the Moon. Lunar colonies in sci-fi usually have medium to high levels of bulls— in their economics. Yeah, I know, nobody reads sci-fi for an economics lesson. But I want it to at least make sense.

So this paper is all about Artemis’s economy and how it works. There are no spoilers for the story, so you can freely read it beforehand if you’re the sort of person who likes bonus material so much you’ll read it before you read the actual story.

Why isn’t this in the book?

Because it’s boring. Hell, if we learned anything from “The Phantom Menace” it’s this: never start a sci-fi story with a description of complex macroeconomics.

You might not even make it through this paper. That’s okay, it’s not supposed to be entertaining. If you get bored, stop reading. This paper is for the one percenters — the folks who have nagging doubts in their suspension of belief because something sticks in their craw. I’m one of those people, and for me the economics has to make sense for a setting to work.

Price point

Andy Weir explores JSCs Lunar Lab. Image Credit NASA James Blair and Lauren HarnettNASA/James Blair and Lauren HarnettIf you could have a lunar vacation for $ 70,000, would you do it? Many people would jump at the chance. They’d get a second mortgage just to pay for it. This, in a nutshell, is the economic foundation of Artemis. It’s all about tourism, and it’s based on the presumption that the price for that tourism can be driven down to the point that ordinary people can afford it.

The pricey part of anything space-related is getting it to space in the first place. It’s incredibly expensive to put mass into LEO (Low Earth Orbit). And if you want to put something on the moon, you have to get a whole ship into LEO that can then travel to the moon. If that impediment were removed, or greatly reduced, we’d have a thriving space tourism industry.

My belief is that we are already on track to a commercial space industry that will do just that.

Money? What money?

I did the research for this in 2015, so all the monetary references in this paper refer to prices and values in 2015 US dollars.

Current cost to LEO

international space station iss nasaNASA

Before I talk about predictions, let’s talk about reality. How much does it cost to put mass into LEO right now?

First off, I start with the assumption that this has to be an actual profitable system. Not something that only exists on government support or subsidy. So I’m disregarding launch systems that are government-run. They have no profit motive, so even if they charge for freight to LEO and even if that charge is low, those are not real economic values. The system would not scale or sustain itself.

The cheapest way to get mass to LEO (at the time of this writing) is with a SpaceX Falcon 9 booster. They charge $ 61.2 million for the launch, and it can put 13,150kg of mass into LEO. So right now, that means it costs $ 4,653 per kilogram.

Now you have some context for comparing the real world to the imagined one I’m about to show you.

My bulls— assumption

Boeing 777REUTERS/Andy Clark

I have absolutely nothing to back this up but instinct. But here it is, the core assumption I have made that enables the world of “Artemis.”

Assumption: The commercial space industry, through competition and engineering advances, will settle down to the same fuel-to-overhead ratio as the modern airline industry.

Okay, so what do I mean by that? How did airlines get into this?

The airline industry is a good parallel for the space industry. Both involve transporting people and freight. Both require extremely expensive, complex vehicles with maintenance overhead. Both consume fuel.

So I have assumed, right or wrong, that a fully profitable commercial space industry would eventually become very much like the commercial airline industry. So let’s look at the airline industry for some clues as to what things cost.

Fuel overhead ratio

Airlines need staff to fly and maintain their aircraft. They need to pay applicable taxes and gate fees. They need to buy new planes, repair worn-out parts, manage their company pension plan, and everything else a service industry has to do. But by far, the largest chunk of their non-payroll operating budget goes to fuel. That’s what costs the most for any given flight.

So the question is this: What percentage of an airline’s total revenues ultimately goes toward buying fuel? That’s what we’re going to work out first.

I have no special understanding of the airline industry. I just went online and did my own research. I looked at ticket prices, noted the price of jet fuel, etc. This could be wildly flawed, but it’s a good place to start.

First off, I had to choose an aircraft to work with. I selected the Boeing 777-300ER. It’s one of the most popular aircraft in the world, servicing long-haul flights be all the major airlines. It’s fuel efficient, effective, and has a stellar safety record.

Here are some stats for the 777-300ER:

The next thing I did was look as some long-haul flights around the world. I wanted to get an even spread of information, so I looked at three different routes, of differing lengths, flown by three different airlines. A more comprehensive study would have to include dozens or maybe hundreds, but I just did three — I’m just trying to make a foundation for a story, not get investor money.

So, to that end, I looked at a United Airlines flight from New York to London, an Air France from Paris to Tokyo, and a Qantas flight from Los Angeles to Sydney. Each of these flights are on 777-300ER aircraft, and their ticket prices are all for the same day in late 2015. Note: the United flight prices are rough averages based on samples of different rates – their web page at the time was cagey on actual ticket prices.

Here’s what I learned:

economics international flights statistics business insider bi graphics.Samantha Lee/Business Insider

For each flight, I noted the price of each class of ticket, then worked out the take — the total amount of money the airline gets if every seat on the plane is sold at its listed cost. The fuel consumed is based on the flight duration and the fuel consumption rate of the aircraft. The cost of that fuel is based on the market price of jet fuel on the day I looked up those tickets, which was $ 0.475/kg. (Actually, the price was 38 cents per liter, but I wanted price per kg and jet fuel has a density of 0.8kg/L).

I was surprised to see that they all has such similar fuel overhead ratios. It makes me feel like my crackpot theory might actually work out.

Yeah, I don’t have enough data, but screw it. I’m going to use the value 16.5%, which is roughly the average of those three. So for the rest of this paper I’ll assume a commercial airline spends 16.5% of its take on fuel.

A commercial spacecraft

spacex falcon 9 rocket launch nrol 76 usaf 34006001860_8c45f28e69_oSpaceX/Flickr (public domain)

Okay, great. I have a rough idea of fuel overhead. So what? What the hell would an efficient commercial spacecraft be like? What would it weigh? How many people could it carry? What would it use for fuel and how much would that fuel cost?

I don’t have answers to any of that, of course. So I’ll just pull a couple more assumptions right out of my ass.

Assumption: A passenger spacecraft would weigh the same as a passenger aircraft capable of carrying the same number of people.

Okay, yeah. That’s a big assumption. But, to be clear, I’m talking about dry weight (not including fuel). And aircraft are pretty similar to spacecraft in a lot of ways. They’re pressure vessels, they have life support systems to keep everyone on board alive, they have big heavy engines, pilots, etc. So that’s what I’m going with.

And for my comparison I’ll use, of course, the Boeing 777-300ER. Same as before. I’m also assuming this is a trip to a transfer ship or space station. So the spacecraft itself doesn’t have to serve as home to the passengers. All it does is get them to orbit. This means there’s really no need for first class at all. The 12-minute trip to orbit does not require high-end seating for anyone. So instead of its normal configuration, I’m going with the high-density version that can seat 550 people.

And now on to the final bit of guesswork.

Assumption: The commercial space industry will use hydrogen-oxygen fuel

The thing that matters most about rocket fuel is a property called “specific impulse.” I don’t want to bore you with physics (I’m here to bore you with economics) so I’ll just say this: specific impulse is a measure of how efficient a rocket fuel is. The higher a fuel’s specific impulse, the less of it you need to get a ship moving a given velocity. And hydrogen-oxygen fuel has the best specific impulse known. Also, it creates water as its exhaust, so there are no pollutants. And finally, it’s cheap to produce.

Right now, there are engineering limitations to using hydrogen-oxygen fuel. The main one being that it burns very hot — hotter than any engine can handle. But again, I’m assuming all these challenges get researched and solved by a profit-hungry industry.

The final piece of the puzzle is the cost of hydrogen and oxygen. This was a little harder to find. I was able to find reliable data on the 2002 price of bulk hydrogen, so I adjusted the 2002 dollars into 2015 dollars and got $ 0.93/kg. As for oxygen, I used the publicly available data on what NASA pays for it — $ 0.16/kg in 2015 dollars. The reaction requires one part hydrogen and eight parts oxygen (by mass), so the total fuel cost is $ 0.245/kg.

That’s the last bit of information we needed to calculate the…

Price of getting a person into space

astronaut floating floats space earth spacesuit zero gravity orbit nasa 576200main_s84 27017_fullNASA

Okay, we have a ship that weighs 165,500kg and we’re going to put 550 passengers on it. We’ll give them 100kg each for their bodies and luggage. That’s a total mass of 215,500kg.

The specific impulse of hydrogen-oxygen fuel is 389s (yes, the unit for measuring specific impulse is “seconds”. It makes no intuitive sense, just roll with it). To get to LEO you need to accelerate by 9,800m/s. LEO actually only requires 7,800m/s, but you lose around 2,000m/s during the ascent to air resistance and other inefficiencies.

Again, I’m skipping over the physics (Tsiolkovsky’s Rocket Equation, if you’re curious) but those numbers mean we’ll need 12.04kg of fuel for every 1kg we want to put into LEO. We want to put 215,000kg into LEO, so we need 2,594,620kg of fuel.

At our calculated fuel cost ($ 0.245/kg) that means the total fuel cost for the launch is $ 637,200.

Now I get to use my airline fuel overhead figure. Airlines have 16.5% fuel overhead ratio and we’re going to assume the space industry will as well. So $ 637,109 is 16.5% of our total ticket take. And that means our total take is $ 3,861,266.

Our ship carries 550 passengers, meaning each passenger will have to pay

$ 7,020.48

Sorry to put that in dramatic bold print with a box around it, but I thought it was exciting. Would you pay seven thousand bucks to go to low Earth orbit? Millions of people would say “yes.”

What about freight?

I looked around at the prices for air freight and found that, on average, you can air mail 200kg of cargo for about the price it would take to send a person. This means people cost twice as much to ship as cargo. That makes sense — cargo doesn’t need seats, air pressure, bathrooms, or complimentary peanuts. For space travel, the cargo ships also wouldn’t need anywhere near as much safety. If a shipment of frozen food blows up on launch, replacing the cargo is trivial.

So I followed the aviation industry’s general pattern and decided that freight to LEO would end up costing about half as much as a human. Or, more importantly, would cost $ 7,020.48 per 200kg. So that means you can get mass to LEO for

$ 35.10 per kg!

Again, I apologize for the drama, but holy s—! That’s a hell of a lot less than the $ 4,653/kg it costs today.

Are such advances reasonable? Well, “Artemis” takes place in the 2080s, which is over 60 years from the time of this writing. Consider the advancements in the aviation industry from its beginnings in the 1930s to the 1990s. Yes, it’s possible. When enough money is up for grabs, anything’s possible.

What about getting from LEO to the Moon?

moonNASA Goddard Spaceflight Center

Okay, so we have people and cargo in LEO. So what? We want them on the Moon. Well, here’s where things bifurcate.

To get people to the Moon, they would make lunar cyclers. These are space hotels in a ballistic orbit (meaning: it doesn’t require fuel to maintain) that regularly visits Earth and the Moon. It would take 7 days to get to the Moon with this system. You still have to accelerate the people to catch up with the space hotel, but at least you don’t have to accelerate the hotel itself over and over. So the fuel cost is minimized.

It’s hard to say how much that would cost. But with a $ 35.10/kg cost to LEO, the mass of the hotel wouldn’t be too much of a financial burden for whatever company built it. I admit I didn’t work out the economics of the space hotel or what it would cost for your stay. But considering how cheap the cost of freight to LEO is, I’m sure it would be small compared to the rest of the trip. On the order of an actual hotel stay (and a hell of a lot more awesome).

But you still have to accelerate people up to the cycler and then decelerate them to land on the Moon.

According to my research, it takes a total of 5,930m/s of delta-v to get from LEO to the surface of the Moon. More physics and math happens here, but it means that for every kilogram of cargo you want to put on the lunar surface, you have to put 4.73kg of mass into LEO. 1kg of actual cargo, and 3.73kg of fuel to get that cargo to the Moon.

So what’s it cost to put freight on the Moon? Well, it would cost 4.73 times what it would cost to put the cargo in LEO. So, while it costs $ 35.10 to put a kilogram into LEO, it would cost $ 166.02 to put it on the surface of the Moon.

So what’s it cost to go to the moon!?

spacex bfr mars spaceship moon base 2SpaceX/YouTube

You have to get your body to LEO ($ 7020), and then soft-landed on the moon. So you end up needing the same overhead – 4.73 times the LEO cost.

$ 33,206.87

Yeah, I did the box/bold thing again. Call the cops, I don’t care. People would be very willing to pay $ 33,000 for a trip to the Moon.

What about the trip back? Well, it’s much cheaper, because you’re leaving the Moon’s gravity, not Earth’s. Plus, you don’t have to use rocket fuel to dump velocity at Earth — you can use the atmosphere to brake with. And you would probably also be using fuel generated on the Moon (aluminum and oxygen, both in massive supply on the Moon, make a good monopropellant), so even it wouldn’t have to be imported.

I didn’t do the math on the return trip, but let’s approximate it to half the trip out. So the round-trip is clocking in at about $ 45,000 (not including a total of 14 days’ stay in the space hotel).

What does it cost to stay on the Moon?

You have to eat. You can eat Gunk if you want — that’s a product created right in Artemis out of algae. It’s nutritionally balanced and grown locally, so it’s nice and cheap. But if you want real food, you’ll have to eat imports. A typical person will eat 500 to 1000 grams of food per day (not including the water weight). We’ve established that lunar freight costs about $ 166/kg. So you’ll spend $ 80 to $ 160 every day just to eat. Not bad for an extravagant vacation.

Total cost

Accommodation and meal prices would be comparable to high-end hotels and restaurants on Earth. Say $ 160/day for food and $ 500/day for a hotel. Of course you’ll want to do stuff while you’re there, which will cost more money. So call it $ 800/day.

However long you want to stay on the moon, add 14 days (for the space hotel that takes you there and back) and multiply by $ 800. That’s your expenses on the trip itself. So let’s say you want a two-week stay. That’s a total of 28 days of expenses at $ 800, so $ 22,400. Round that up to $ 25,000 because vacations always cost more than you expect. That plus the $ 45,000 travel costs totals $ 70,000.

So I ask again: Would you pay $ 70,000 for a lunar vacation?

Plasma explosions from the sun over billions of years have all but stripped Mars of its atmosphere. But a new discovery by NASA shows that remnants of the Red Planet’s magnetic field can be found in the form of a rotating ‘tail’.

Invisible to the naked eye, the so-called ‘magnetotail’ was recently detected by NASA’s Mars Atmosphere and Volatile Evolution Mission spacecraft (MAVEN).

MAVEN was launched in 2013 to trace the Martian world’s climate history and determine if it may have once sustained life.

The ‘tail’ phenomenon is caused by solar winds whipping over the surface of the planet, resulting in the remaining pockets of Mars’ once-protective magnetic field joining with sun plasma particles.

The process can cause magnetic forces to be twisted by the 1.6 million kph solar winds, said Gina DiBraccio, of NASA’s Goddard Space Flight Center. It may also be contributing to the destruction of Mars’ thin atmosphere, allowing gases to escape into space.

“We found that Mars’ magnetic tail, or magnetotail, is unique in the solar system,” DiBraccio said.

“Our model predicted that magnetic reconnection will cause the Martian magnetotail to twist 45 degrees from what’s expected based on the direction of the magnetic field carried by the solar wind.”

The “unique” magnetic field movement was measured and mapped using the MAVEN spacecraft’s magnetometer. Over the next couple of years, NASA plans to explore exactly how significant the impact of magnetic movement is to the Red Planet’s atmospheric loss.

Mars was hit by an unexpected blast from the sun in September, doubling radiation levels on the surface and causing an incredibly bright aurora over the planet.

The “solar event” took place on September 11, and was observed by Nasa’s missions in orbit and on Mars’ surface.

“Nasa’s distributed set of science missions is in the right place to detect activity on the sun and examine the effects of such solar events at Mars as never possible before,” said Elsayed Talaat, program scientist for NASA’s Atmosphere and Volatile Evolution (MAVEN) mission.

The aurora was more than 25 times brighter than any previously observed by MAVEN, which has been studying the Martian atmosphere’s interaction with the solar wind since 2014.

The strong solar blast also more than doubled radiation levels on the Red Planet’s surface, according to readings by Nasa’s on-the-ground mission, the Curiosity rover.

Another “strange” element of the phenomenon, according to Nasa, was that the unseasonable blast occurred during a usually-quiet period within the sun’s 11-year sunspot and storm-activity cycle.

“The current solar cycle has been an odd one, with less activity than usual during the peak, and now we have this large event as we’re approaching solar minimum,” said Sonal Jain a member of MAVEN’s Imaging Ultraviolet Spectrograph instrument team.

The blast was so strong that readings remained high on the surface for more than two days and was big enough to be detected from Earth – even though we sit on the opposite side of the sun from Mars.

“This is exactly the type of event both missions were designed to study, and it’s the biggest we’ve seen on the surface so far,” said RAD Principal Investigator Don Hassler.

“It will improve our understanding of how such solar events affect the Martian environment, from the top of the atmosphere all the way down to the surface,” Hassler added.

It’s been three months since the rather shocking movie news broke that Phil Lord and Chris Miller had been fired from the Star Wars anthology film focused on Han Solo. Even though a large portion of the filming on Han Solo was complete, disagreements with Lucasfilm resulted in Lord and Miller being let go and eventually replaced with Ron Howard. While the directing duo may not have been able to reveal their full vision of a galaxy far, far away, they’re still headed back beyond the stars for their next feature, an adaptation of a new novel from the author of The Martian. See details on the next Lord and Miller movie below.

Andy Weir hit it big when his self-published novel The Martian became a best-seller and then a big blockbuster film from Ridley Scott. The strength of The Martian‘s success was enough for 20th Century Fox and New Regency to preemptively pick up the rights to Weir’s next novel, Artemis. Now THR reports that Phil Lord and Chris Miller have jumped aboard the sci-fi film, described as a “near-future thriller that follows directionless 20-something, Jazz, chafing at the constraints of her small town, Artemis, which so happens to be the first and only city on the moon. Jazz, a budding smuggler, unwittingly finds herself in the middle of a conspiracy for the control of her home town.”

Lord and Miller, who directed the successful 21 Jump Street films as well as The Lego Movie, made big Star Wars headlines both when they were first hired to helm the Han Solo solo film and then when they were fired, with the filmmakers releasing a statement that said their “vision and process weren’t aligned with our partners on this project. We normally aren’t fans of the phrase ‘creative differences’ but for once this cliché is true. We are really proud of the amazing and world-class work of our cast and crew.” There is, of course, a slight irony in the fact that the first film for the duo since their firing will be another intergalactic adventure.

As for what type of space adventure Artemis will be, some hints can be gleaned from a statement author Andy Weir released about the book:

“I’m really excited about Artemis. I got to do the science-dork stuff I love, but this time with a much more complex and character-driven plot. It’s a big stretch for me, but I think it came out well. Hopefully the readers will agree…The Martian was a straight-up human-versus-nature story where the goal was simple survival. Artemis is a much more complicated crime story with mysteries involved. It was much more difficult to write but also a lot more interesting I think.”

Artemis will hit book stores on November 17, 2017.
