]]> https://briefnews.eu/nasas-dart-spacecraft-smashes-into-an-asteroid-on-purpose/feed/ 0 NASA successfully smacked its DART spacecraft into an asteroid https://briefnews.eu/nasa-successfully-smacked-its-dart-spacecraft-into-an-asteroid/ https://briefnews.eu/nasa-successfully-smacked-its-dart-spacecraft-into-an-asteroid/#respond Tue, 27 Sep 2022 02:14:29 +0000 https://briefnews.eu/nasa-successfully-smacked-its-dart-spacecraft-into-an-asteroid/ After nearly a year in transit, NASA's experimental Double Asteroid Redirection Test (DART) mission, which sought to answer the questions, "Could you potentially shove a asteroid off its planet-killing trajectory by hitting it with a specially designed satellite? How about several?" has successfully collided with the Dimorphos asteroid. Results and data from the collision are still coming in but NASA ground control confirms that the DART impact vehicle has intercepted the target asteroid. Yes, granted, Dimorphos is roughly the size of an American football stadium but space is both very large and very dark, and both asteroid and spacecraft were moving quite fast at the time.

DART strike
NASA

"It's been a successful completion of the first part of the world's first planetary defense test," NASA Administrator Bill Nelson said after the impact. "I believe it's going to teach us how one day to protect our own planet from an incoming asteroid. We are showing that planetary defense is a global endeavor and it is very possible to save our planet."

NASA launched the DART mission in November, 2021 in an effort to explore the use of defensive satellites as a means of planetary defense against Near Earth Objects. The vending machine-sized DART impactor vehicle was travelling at roughly 14,000 MPH when it fatally crossed Dimorphos' path nearly 68 million miles away from Earth. 

Whether future iterations of a planetary defense system brimming with satellites willing to go all June Bug vs Chrysler Windshield against true planet-killer asteroids remains to be seen. Dimorphos itself is the smaller of a pair of gravitationally-entangled asteroids — its parent rock is more than five times as large — but both are dwarfed by the space rock that hit Earth 66 million years ago, wiping out 75 percent of multicellular life on the planet while gouging out the Gulf of Mexico. 

The Moment of DART's Death
NASA

The DART team will likely be poring over the data generated by both the impactor and cameras released before the spacecraft made its final approach for days to come. However the team will consider shortening the orbital track of Dimorphos around Didymos by 10 minutes an ideal outcome, though any change of at least 73 seconds will still be hailed as a rousing success. The team will have to observe Dimorphos' orbit for half a day to confirm their success, as the moonlet needs nearly 12 hours to complete an circuit around Didymos.

NOTE: NASA is offering two feeds of the event — read on for more details.

NASA is about to deliberately crash a spacecraft into a distant asteroid in a first-of-its-kind planetary defense test.

The hope is that by slamming a spacecraft into an asteroid at a speed of around 15,000 mph, we can alter its orbit, thereby confirming a way to direct potentially hazardous space rocks away from Earth.

To be clear, NASA’s target asteroid, Dimorphos, poses no threat to Earth. This is merely an effort to determine the viability of such a process if we do ever spot a large asteroid on a collision course with Earth.

NASA’s Double Asteroid Redirection Test (DART) spacecraft, which launched in November 2021, will reach Dimorphos on Monday, September 26, and the whole event will be streamed online.

Mission overview

The 530-feet-wide Dimorphos asteroid is orbiting another one called Didymos, which is about half a mile across.

When DART smashes into Dimorphos at a location about 6.8 million miles from Earth, telescopes here on the ground will analyze the asteroid’s orbit to see if it has changed in any way.

DART is equipped with an instrument called the Didymos Reconnaissance and Asteroid Camera for Optical Navigation (DRACO). DRACO is guiding DART to its final destination and will also provide a real-time feed from the spacecraft, sending one image per second back to Earth.

NASA says that in the hours before impact, the screen will appear mostly black, apart from a single point of light marking the location of the binary asteroid system that the spacecraft is heading toward.

But as the moment of impact draws closer, the point of light will get bigger and eventually detailed asteroids will be visible.

Last week, DART also ejected a camera called the Light Italian CubeSat for Imaging Asteroids (LICIACube). This will fly past Dimorphos about three minutes after the impact, capturing high-resolution images of the crash site, including the resulting plume of asteroid material and possibly the newly formed impact crater.

How to watch

The DART spacecraft is set to impact the Dimorphos asteroid at 7:14 p.m. ET (4:14 p.m. PT) on Monday, September 26.

NASA is offering two feeds of the event. The first, embedded at the top of this page, offers the most up-to-date DRACO camera feed and starts at 6 p.m. ET (3 p.m. PT). The second feed, which can be found on this page, offers similar coverage and begins half an hour earlier at 5:30 p.m. ET (2:30 p.m. PT).

NASA said that after impact, the feed will turn black due to a loss signal. Then, after about two minutes, the stream will show a replay showing the final moments leading up to impact.

At 8 p.m. NASA will livestream a press briefing discussing the mission.

But it has also been busy studying Jupiter’s moons, including capturing images of Io and Europa and capturing not only the sights but also the sounds of the moon Ganymede. Now Juno will get to see Europa in even more detail as it is set to perform a close flyby of the icy moon this week.

On Thursday, September 29, Juno will pass within 222 miles (358 kilometers) of Europa and should be able to capture some of the highest-ever resolution images of its surface, as well as gather data on its interior and the edge of its atmosphere. Europa is a particularly exciting place to study because it is thought to be one of the best places in the solar system for life to have evolved apart from Earth. It is getting its own mission called Europa Clipper to be launched in 2024.

“Europa is such an intriguing Jovian moon, it is the focus of its own future NASA mission,” said Juno Principal Investigator Scott Bolton of the Southwest Research Institute, in a statement. “We’re happy to provide data that may help the Europa Clipper team with mission planning, as well as provide new scientific insights into this icy world.”

Getting the spacecraft to pass so close to the moon while keeping it safe requires tremendous coordination. The maneuvers required to get close to Europa will change Juno’s orbit around Jupiter from a period of 43 days to 38 days. And the relative speeds are extremely fast, so the team will begin data collection one hour before the spacecraft’s closest approach to the moon.

“The relative velocity between spacecraft and moon will be 14.7 miles per second (23.6 kilometers per second), so we are screaming by pretty fast,” said John Bordi, Juno deputy mission manager at JPL. “All steps have to go like clockwork to successfully acquire our planned data, because soon after the flyby is complete, the spacecraft needs to be reoriented for our upcoming close approach of Jupiter, which happens only 7 ½ hours later.”

As it is so far from the sun, the surface of Europa is very cold and is covered in a thick layer of ice. But researchers believe there is a saltwater ocean beneath this crust, which could potentially support life. They know this because previous research has observed plumes of water being thrown up into the moon’s atmosphere. If we are very, very lucky, there is even a chance that Juno could catch such a plume to observe it in more detail.

“We have the right equipment to do the job, but to capture a plume will require a lot of luck,” said Bolton. “We have to be at the right place at just the right time, but if we are so fortunate, it’s a home run for sure.”

The Dimorphos asteroid poses no threat to Earth, but NASA wants to find out if it can change an asteroid’s flight path by crashing a spacecraft into it so that it can protect our planet from hazardous space rocks in the future.

The image (below) — captured by DART’s Didymos Reconnaissance and Asteroid Camera (DRACO) in July and released by NASA this week — shows Didymos, the double-asteroid system that includes the spacecraft’s target, Dimorphos (inside the left circle), about 20 million miles from DART.

The image actually comprises 243 separate captures and shows the light from the asteroid Didymos and its orbiting moonlet Dimorphos.

NASA said its team wasn’t sure if DRACO would be able to spot the asteroid yet, but after stitching together the numerous images it was able to enhance the final picture and pinpoint Didymos.

DRACO is a key part of DART — indeed it’s the only instrument the spacecraft is carrying — as its data will be used to guide the spacecraft toward the asteroid, especially in the final four hours prior to impact when DART will be required to navigate by itself.

“This first set of images is being used as a test to prove our imaging techniques,” Elena Adams, DART mission systems engineer at the Johns Hopkins Applied Physics Laboratory, said in a release. “The quality of the image is similar to what we could obtain from ground-based telescopes, but it is important to show that DRACO is working properly and can see its target to make any adjustments needed before we begin using the images to guide the spacecraft into the asteroid autonomously.”

After making a number of trajectory correction maneuvers over the next three weeks, the team is confident that 24 hours prior to hitting the asteroid, it will know the impact point to within a distance of 1.2 miles (2 kilometers).

Scientists have calculated that Earth is at most risk from asteroids greater than 460 feet (140 meters) in size. There are plenty of asteroids out there that have yet to be discovered by astronomers, so a successful test in just a few weeks’ time could prove vital for our planet’s safety.

NASA is reporting that there has been an “issue with the booster” on the Soyuz craft that’s currently taking astronauts Nick Hague of NASA and cosmonaut Alexey Ovchinin to the International Space Station (ISS). Details are sparse at the moment, but it appears that the capsule is making a “ballistic descent,” descending at a high rate of speed, and will soon attempt an emergency landing. Crews are reportedly underway to the designated landing site, with an ETA of about an hour.

Update 10/11/2018 5:16 AM ET: According to Reuters news editor Gerry Doyle, the capsule was sited under parachute in Kazhakstan. Shortly afterwards, it touched down, and the crew is reportedly fine and has made radio contact. “I just rode a malfunctioning booster for a few minutes and had to abort,” one of the astronauts reportedly said.

Update 10/11/2018 5:25 AM ET: NASA has affirmed that astronaut Nick Hague of NASA and cosmonaut Alexey Ovchinin are in contact with rescue crews, and that they’re in good condition, though no doubt a little shook up.

A Russian Progress cargo spacecraft on a Soyuz booster carrying supplies for the International Space Station crew has successfully completed its record-breaking two-orbit trip in less than four hours.

The Progress MS-09 blasted off atop a Soyuz-2.1a rocket at 21:51 GMT Monday from the Baikonur Cosmodrome in Kazakhstan. Some 1.5 hours and several thruster firings after liftoff, the spacecraft’s onboard computers initiated the automated rendezvous sequence. The craft completed its radar-guided docking with the station’s Pirs module at 01:31 GMT Tuesday.

It was the third attempt to execute the short two-orbit flight scheme for the Progress MS freighter, which required a coordinated effort to realign the orbit of the ISS.Two previous attempts were hindered by delays in the final moments of the countdown that exceeded narrow launch opportunities for the fast-track flight.

Russian cosmonauts Oleg Artemyev and Sergey Prokopyev were on board the station and ready to take over manual control of the craft should any problems occur, but the docking proceeded in a fully automatic mode. The craft has brought over 2.5 tons of water, fuel, food and other supplies, extending the entire crucial provision supply to at least mid-January 2019.

TESS, NASA’s new exoplanet-hunting spacecraft, has captured its first image ever, giving us a glimpse of what its powerful “eyes” can see. The spacecraft’s science team used one of its four cameras to snap a two-second test exposure as part of their preparations now that TESS is only a month away from officially starting its science operations. Their photo shows over 200,000 stars with the southern constellation Centaurus at the center and one of the brightest stars in the night sky, the Beta Centauri, visible on the lower left edge (see the full image below the fold).

Despite the number of stars in the photo, it represents just a tiny part of what TESS can keep its eyes on — the spacecraft can cover over 400 times as much sky as what’s shown in the picture. It’s expected not just to find thousands more previously undiscovered exoplanets, but also to gather data on them. NASA will then use the James Webb Telescope to take a closer look at the most promising TESS findings in order to study their atmospheres. The hope is to find habitable, Goldilocks (not too hot, not too cold) planets in neighboring galaxies and beyond.

When the spacecraft’s ground team took the photo, TESS had just finished a lunar flyby 5,000 miles above the moon’s surface. Now, it’s preparing for one final thruster burn on May 30th in order to enter its highly elliptical orbit around our planet. Once it’s fully operational, TESS will take its first science-quality (or first light) image, which will be released sometime in June.

It’s been a long three-and-a-half years since the Orion spacecraft first launched into space in December 2014, making a successful shake-out flight. But now, NASA’s program aimed at building a large, deep-space capsule capable of sending astronauts to and from lunar orbit is finally ramping back up toward a series of test flights.

In less than a year, a boilerplate model of the Orion spacecraft will be jettisoned from its rocket at 55 seconds after liftoff to test the vehicle’s launch abort system. Provided that goes well, about a year after that, the Orion spacecraft will be sent into lunar orbit for longer than a week for a shakedown cruise. Finally, as early as June 2022, two to four astronauts will fly aboard Orion into lunar orbit, sending humans into deep space for the first time since 1972.

This isn’t exactly a rapid cadence of flights, but three missions in four years would represent a remarkable increase from the vehicle’s flight rate to date—one in 13 years. “Our destiny is to explore, so you want to get your tests behind you and get humans on the spacecraft, and start that exploration,” Annette Hasbrook, an assistant manager for the Orion program in Houston, told Ars.
