NASA’s Mars rover marvels at ‘big chunky weirdo’

By Trevor Mogg Published July 27, 2023

NASA’s Perseverance rover has been busy exploring Mars since landing there in spectacular fashion in February 2021.

The car-sized vehicle is equipped with a bunch of science tools and cameras to help it in its quest to find evidence of ancient microbial life on the distant planet. It’s also gathering together samples of Martian rock and soil for return to Earth in the ambitious Mars Sample Return mission. Additionally, the current mission offers an opportunity to test robotic technology that could be further developed for the first crewed mission to Mars.

Perseverance’s X (formerly Twitter) account is a hive of activity, with regular first-person reports keeping the rover’s 3 million fans up to date with its Mars-based activities.

Its latest tweet, shared this week, features an image of an unusually large Martian boulder that Perseverance describes as a “big chunky weirdo.”

“I spotted this boulder from a distance and have come in for a closer look,” the rover said. “It’s harder than most, with an odd shape and makeup.” We’re still waiting for an update.

Look at this big chunky weirdo. 🪨 I love it.

In response to a follower’s inquiry, Perseverance confirmed that it is currently positioned atop the delta/fan formation at Jezero Crater, a dried-up lake that scientists believe offers a good chance of holding evidence of ancient life if any is to be found.

Perseverance said the rocks in the photo “look like they were brought in by an ancient river” that once flowed into the lake.

“Rock nerds rejoice!” the rover said in another tweet. “From big boulders to tiny pebbles, the ancient riverbed I’m exploring right now has it all. Washed in from upstream, these fragments can help my team uncover the river’s past and its potential for supporting ancient life.”

It’s certainly an exciting time for the Perseverance team working at NASA’s Jet Propulsion Laboratory (JPL) in Southern California, which is also overseeing achievements by Ingenuity, a drone-like machine that in 2021 became the first aircraft to achieve powered, controlled flight on another planet.

NASA’s Mars rover collects rock sample ‘unlike anything we’ve seen before’

Perseverance's 26th rock sample collected from the Martian surface.

NASA’s Mars Perseverance rover acquired this image of its 26th collected rock sample, named “Silver Mountain,” using its onboard Sample Caching System Camera, located inside the rover's underbelly. The camera looks directly down into the top of a sample tube to take close-up pictures of the sampled material and the tube ahead of sealing and storage. NASA/JPL-Caltech

Elon Musk voices renewed hope for first crewed Mars mission

In this artist’s concept, NASA astronauts drill into the Martian subsurface. The agency has created new maps that show where ice is most likely to be easily accessible to future astronauts.

With his new buddy Donald Trump now back in the White House, SpaceX boss Elon Musk has renewed hope of getting the first humans to Mars before the end of this decade.

During his inauguration speech on Monday, President Trump said that his administration “will pursue our manifest destiny into the stars, launching American astronauts to plant the Stars and Stripes on the planet Mars.”

NASA has two ideas for how to get samples back from Mars

An illustration of NASA's Sample Return Lander shows it tossing a rocket in the air like a toy from the surface of Mars.

NASA has big goals for Mars. It wants to collect the first-ever samples from the Martian surface and deliver them back to Earth in an ambitious mission called Mars Sample Return. But even in its development phase, the mission has run into problems. With a ballooning budget and unrealistic time frame, NASA decided last year that it needed a new approach to the mission, and now it has announced an update. It's working on two ideas, with the best to be chosen in 2026.

“Pursuing two potential paths forward will ensure that NASA is able to bring these samples back from Mars with significant cost and schedule saving compared to the previous plan,” said NASA Administrator Bill Nelson. “These samples have the potential to change the way we understand Mars, our universe, and – ultimately – ourselves. I’d like to thank the team at NASA and the strategic review team, led by Dr. Maria Zuber, for their work.”
