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.

NASA on Saturday announced that it will no longer attempt to launch its Artemis I mission on Tuesday, September 27, as Tropical Storm Ian continues developing in the Caribbean Sea.

Instead of preparing the massive Space Launch System rocket for liftoff in three days, teams at Kennedy Space Center in Florida will instead start to configure the ground systems and vehicle for a potential roll back to a large hangar, the Vehicle Assembly Building. Sheltering inside this building would protect the $ 4 billion rocket and Orion spacecraft from any foul weather due to Ian.

Earlier, NASA had said it would make a decision by Saturday afternoon on whether to roll the Artemis I mission back inside the hangar. However, in its announcement on Saturday the agency said it would now make that decision on Sunday.

On Friday afternoon, senior officials at NASA joined a teleconference to speak with reporters about the current plan to launch the Artemis I mission from Kennedy Space Center in Florida. This will be the third attempt to get the massive Space Launch System rocket off the ground and boost the Orion spacecraft into lunar orbit for an approximately 40-day uncrewed test flight before returning to Earth.

The rocket is ready, officials said. During fueling tests and launch attempts NASA has been bedeviled by hydrogen propellant leaks, as the tiny molecule is difficult to handle and constrain at super-chilled temperatures. However, following a longer-than-expected, but ultimately successful propellant loading test on Wednesday, NASA engineers expressed confidence in their revamped fueling procedures.

NASA has also reached an accord with US Space Force officials to extend the battery life for the rocket’s onboard flight termination system. This left only weather as a potential constraint to a planned launch attempt for Tuesday, September 27, at 11:37 am EST (15:37 UTC). The problem is that weather now poses a significant threat to the schedule due to a tropical depression that will likely track toward Florida in the coming days. There is an 80 percent chance of unacceptable weather during the launch window.

NASA had to test adding super-cooled fuel to the Space Launch System's tanks to confirm the repairs it made after it scrubbed the mission's second launch attempt in late August. The ground team at Kennedy Space Center spotted a persistent hydrogen leak affecting one of the fuel lines on the SLS at the time and tried to fix it the day of three times. In the end, the team was unsuccessful and decided to postpone the mission.

The team determined a few days later that the leak was triggered when the SLS rocket's core booster tank went through a brief overpressurization. To prevent the same incident from happening, the team adjusted procedures for filling the rocket's tank with propellants, and it involves transitioning temperatures and pressures more slowly to prevent rapid changes that could cause leakage. The team's engineers also replaced the rocket's liquid hydrogen seals after discovering a small indentation in one of them that may have contributed to the leak. 

While the engineers encountered another hydrogen leak during the fuel test, their troubleshooting efforts worked this time around and got the leak to "within allowable rates." That allowed them to conduct the pre-pressurization test, which brought up the liquid hydrogen tank's pressure level to match what it would experience just before an actual launch. 

Artemis 1 launch director Charlie Blackwell-Thompson said the test went "really well" and that the team was able to accomplish all the objectives it set out to do. NASA will now evaluate data from the test before deciding if it can schedule another launch for the mission on its target date of September 27th.

The space agency said it is now aiming for Tuesday, September 27, for its next launch attempt. If that fails, it will try to send the rocket skyward on Sunday, October 2.

Last week, NASA said it was targeting Friday, September 23 for a launch attempt, but that date has now been scrapped.

Specifically, the September 27 launch attempt involves a 70-minute launch window that opens at 11:37 a.m. ET, with the Orion capsule arriving back on Earth about six weeks later on November 5. If that launch is unable to proceed, NASA will aim instead for October 2, with a 109-minute launch window opening at 2:52 p.m. ET and the spacecraft returning to Earth on November 11.

Prior to the attempted September 27 launch, NASA said it needs to perform a fueling test, an exercise it plans to conduct no earlier than Wednesday, September 21.

“The updated dates represent careful consideration of multiple logistical topics,” the agency said in a release on Monday, adding that the new timetable “also allow managers to ensure teams have enough rest and to replenish supplies of cryogenic propellants.”

NASA called off the August 29 launch attempt with just 40 minutes on the countdown clock after engineers identified an issue with one of the engines on the rocket’s core stage.

Five days later, it halted final preparations for another launch after a fuel leak came to the engineers’ attention.

The 97-meter-tall rocket and Orion spacecraft remain in place on the launchpad at the Kennedy Space Center in Florida.

The uncrewed Artemis I mission will send the Orion on a fly-by of the moon, with the spacecraft returning to Earth six weeks later. If the test mission is a success, NASA will send astronauts on the same flight path for the Artemis II mission. Then, possibly in 2025, Artemis III will endeavor to put the first woman and first person of color on the lunar surface in the first crewed moon landing in five decades.

NASA wants to use the early Artemis missions to build a moon base for long-duration crewed missions, using what it learns for the first astronaut mission to Mars, possibly in the late 2030s.

On Friday, engineers replaced the leaky seal that forced the agency to scrub its most recent attempt to launch Artemis 1. On September 3rd, a fitting on one of the fuel lines to the SLS began leaking hydrogen. Ground crew at Kennedy Space Center tried to troubleshoot the problem three times, only for the leak to persist and force NASA to call off the launch attempt. On Friday, engineers also replaced the seal on a 4-inch hydrogen “bleed line” that was responsible for a smaller leak during an earlier August 29th launch attempt.

With the new gaskets in place, NASA plans to conduct a fueling test to verify they’re working as intended. The dry run will see engineers attempt to load the SLS with all 736,000 gallons of liquid hydrogen and oxygen it would need during a regular flight. NASA hopes to successfully complete that test as early as September 17th. “This demonstration will allow engineers to check the new seals under cryogenic, or supercold, conditions as expected on launch day and before proceeding to the next launch attempt,” the agency said.

On Thursday, NASA announced it was targeting September 23rd for another go at putting Artemis 1 into space, with September 27th as a backup. Whether it can make those dates will depend on next week’s fueling test and a decision from the US Space Force. Flight regulations require that NASA test the battery of Artemis 1’s flight termination system every 20 days. That’s something it can only do within the Kennedy Space Center’s Vehicle Assembly Building. The Space Force previously granted the agency an extension on the 20-day deadline. NASA has now asked for another waiver.

Following failed attempts to blast the Space Launch System (SLS) rocket skyward on August 29 and September 3, NASA engineers at the Kennedy Space Center launch site in Florida have been working tirelessly to fix the issues that caused those countdowns to halt.

With the rocket still on the launchpad, the to-do list has included replacing the seals at the center of the hydrogen leak that occurred during fueling operations for the rocket’s second launch attempt.

“Engineers have replaced the seals associated with the hydrogen leak detected during the #Artemis I launch attempt on Sept. 3,” NASA confirmed on Saturday. “The teams will inspect the new seals over the weekend and assess opportunities to launch.”

The launch team is now aiming to conduct a tanking demonstration as soon as September 17, a procedure designed to check the new seals under super-cold conditions that replicate the conditions on launch day.

The tanking demonstration will involve loading liquid hydrogen and liquid oxygen in the SLS rocket’s core stage and interim cryogenic propulsion stage and getting to a stable replenish state for both propellants, NASA said.

Engineers will also conduct several other tests to validate the ground and flight hardware and software systems’ ability to perform the necessary functions required to thermally condition the engines for flight.

Once all of these preparations have been successfully carried out, the team will assess the data and make a final decision on whether to go for launch before the end of this month.

The upcoming Artemis I missions is one of the most highly anticipated NASA events in years as it will usher in a new era of space exploration that will soon involve astronaut missions to the moon and even Mars.

When the uncrewed Artemis I launch takes place hopefully in the coming weeks, the most powerful rocket NASA has ever built will propel the new Orion spacecraft toward the moon, where it’ll perform a fly-by before returning to Earth about six weeks later.

A successful mission will pave the way for Artemis II that will see the Orion take the same route though this time with a crew on board.

Artemis III, which could take place as early as 2025, will endeavor to put the first woman and first person of color on the lunar surface in what will also be the first astronaut landing since the final Apollo mission in 1972.

But that’s just the start, as NASA wants to build a moon base for long-duration astronaut missions, and also send the first crew to Mars in a historic voyage that could take place in the late 2030s. But before that can happen, there is still much work to be done.

KENNEDY SPACE CENTER, Fla.—America’s space agency on Saturday sought to launch a rocket largely cobbled together from the space shuttle, which itself was designed and built more than four decades ago.

As the space shuttle often was delayed due to technical problems, it therefore comes as scant surprise that the debut launch of NASA’s Space Launch System rocket scrubbed a few hours before its launch window opened. The showstopper was an 8-inch diameter line carrying liquid hydrogen into the rocket. It sprang a persistent leak at the inlet, known as a quick-disconnect, leading on board the vehicle.

Valiantly, the launch team at Kennedy Space Center tried three different times to stanch the leak, all to no avail. Finally at 11:17 am ET, hours behind on their timeline to fuel the rocket, launch director Charlie Blackwell-Thompson called a halt.

The agency was forced to scrub Saturday’s launch after staff at Kennedy Space Center failed to fix a persistent leak in a liquid hydrogen connection point on the agency's next-generation Space Launch System super heavy-lift rocket. 

NASA detected the leak at 7:23AM ET and tried to troubleshoot the problem in a few different ways, but after three failed attempts ground crew recommended a "no go" for Saturday's launch attempt. Monday's attempt was cut short after one of the four on the SLS could not reach the appropriate temperature to send Artemis 1 into space.    

"The Artemis I mission to the Moon has been postponed. Teams attempted to fix an issue related to a leak in the hardware transferring fuel into the rocket, but were unsuccessful," NASA said on Twitter. 

Provided NASA can fix the leak on Launch Pad 39B, the agency has one last window it can attempt a launch before a major delay becomes inevitable. If it can't fly by September 5th, NASA will need to roll the SLS back to the Kennedy Space Center's Vehicle Assembly Building to conduct a test of the rocket's flight termination system. At that point, the earliest Artemis 1 could get underway would be September 19th, but an October launch would be more likely.
