NASA rover’s first Mars rock sample crumbled, but it’s going in for another

The Perseverance rover is eyeing a new sample, and hopefully it’s way more sturdy. NASA wants to bring the rock back to Earth one day.

This story is part of Welcome to Mars, our series exploring the red planet.

Earlier in August, NASA’s Perseverance team thought it was about to celebrate the triumphant collection of the rover’s first Martian rock sample, but all they got was an empty tube. Perseverance is now ready to try again with a different and hopefully much less crumbly rock.

The sampling operation is exciting in part because NASA intends to one day send a mission to pick up the samples from the Jezero Crater and bring them back to Earth for study.

NASA has now zeroed in on a rock nicknamed «Rochette.» The rover will rough up the rock a bit with an abrading tool to get a better look and help the team decide if this is indeed the rock they want to sample. If it’s a go, the rover will drill into the rock, collect a pencil-thick core piece and seal it into a sample tube.

Perseverance is checking out a craggy ridge named «Citadelle.» «The ridge is capped with a layer of rock that appears to resist wind erosion, a sign it’s more likely to hold up during drilling,» NASA said in a statement on Thursday. NASA tweeted out some views of the area and the potential rock target.

After the surprising result with the first sample attempt, the team will use one of the rover’s cameras to look into the sample tube and make sure there’s rock inside before sealing it.

The first tube won’t go to waste. NASA scientists are excited the rock-less tube is full of Mars’ atmosphere instead. «By returning samples to Earth, we hope to answer a number of scientific questions, including the composition of Mars’ atmosphere,» said Perseverance project scientistKen Farley.

Perseverance is capturing images of the Mars landscape, studying the geology and weather and looking for signs of ancient microbial life. The successful capture of its first rock core will be an event worth cheering about.

You Can Watch an Exclusive Avatar: Fire and Ash Scene on TikTok Right Now

Disney and TikTok partner on an immersive content hub for James Cameron’s latest movie about the alien Na’vi.

If you’re not quite ready to head to the theater to watch Avatar: Fire and Ash, an exclusive scene preview might sell you on the visual spectacle. As part of a new collaboration with the social media giant, Disney is posting snippets of its new movie to its TikTok account.

This scene isn’t part of any trailer and won’t be posted to other social media accounts, making TikTok the only place you can view it — unless you buy a movie ticket. A first look at the new movie’s scenes isn’t the only Avatar-related bonus on the social media platform right now, either. TikTok has partnered with the house of mouse to bring an entire «immersive content hub» to the app.

A special section of TikTok includes quizzes and educational videos that explore the alien world of Pandora shown off in the movies. On TikTok, you can take a personality quiz to find out what Na’vi clan you most closely align with and unlock a special profile picture border to use on your account.

Science and fiction blend together with a series of videos from real doctors who explain the basis for some of Avatar’s world-building. If you want to learn about exoplanets or how realistic the anatomy of the movie’s alien animals is, these videos will feed your brain while still providing entertainment value.

Perhaps the most enticing part of Disney’s latest social media collaboration is the opportunity for fans to win prizes and trips. TikTok creators who make edits with the #TikTokAvatarContest hashtag are entered into a competition to win Avatar merchandise. The biggest winners will be able to take a trip to visual effects studio Wētā Workshop in New Zealand or visit Avatar director James Cameron’s Lightstorm Entertainment Studio in Los Angeles.

Avatar: Fire and Ash is the third installment in director Cameron’s cinematic passion project. While the first Avatar movie was released in 2009, Cameron didn’t release another entry in the franchise until 2022. In total, there is a five-movie arc planned for the indigo alien Na’vi on the moon of Pandora.

The Avatar movies are known for pushing the boundaries of CGI visual effects in cinema. They are also historically big winners at the box office: the original Avatar is the highest-grossing film of all time, earning $2.9 billion across its theatrical releases. Its sequel, Avatar: The Way of Water, is the third-highest-grossing film of all time, trailing Avengers: Endgame. You can stream those movies on Disney Plus.

It remains to be seen whether Avatar: Fire and Ash will financially live up to its predecessors. The film currently has mixed reviews from critics on Rotten Tomatoes.
