Curiosity’s new selfie a reminder that the plucky rover is still busy on Mars

NASA’s Curiosity rover is back in the spotlight after the space agency shared a recent selfie snapped by the veteran Mars explorer.

While NASA’s newer, more advanced Perseverance rover tends to get all the attention these days, Curiosity, which landed on the martian surface in 2012, continues to investigate the faraway planet in a bid to learn more about the distance location.

The latest image (below) beamed to Earth by Curiosity shows the plucky rover some way in front of the Greenheugh Pediment rock structure, while the landform viewable in the middle distance on the right is called Rafael Navarro Mountain.

According to NASA, Curiosity is now making for Maria Gordon Notch, the U-shaped opening behind the rover to the left.

NASA’s Curiosity rover took the ultrawide image using the Mars Hand Lens Imager, or MAHLI, located at the end of its robotic arm, which doubled as a selfie stick.

The picture is actually made up of 81 separate images taken in a way that enabled Curiosity’s arm to stay out of shot, giving it the appearance of standing alone.

Explaining how it achieves the effect, NASA said the process begins with the rover’s arm using various wrist motions and turret rotations to enable MAHLI to capture all of the component images. Having so many pictures taken from slightly different angles allows for the creation of a carefully stitched selfie in which appearances of the arm are eliminated by overlapping some of the images.

NASA also posted a cropped version of the selfie that offers a clearer look at its 9-year-old rover.

Curiosity is working in a location around 2,300 miles (3,700 km) from Perseverance, which landed in Mars’ Jezero Crater in February 2021.

Still in full working order, Curiosity has been spending its time carrying out a range of missions while also sending back incredible images for earthlings to enjoy.

Its discoveries to date include evidence that persistent liquid water once existed on Mars’ surface, and that the planet once had the right conditions to support living microbes. Perseverance is continuing this work and searching for evidence of ancient microbial life.

NASA and Boeing reveal new date for first crewed Starliner flight
A graphic rendering of the Boeing Starliner orbiting Earth.

NASA and Boeing had been hoping to perform the first crewed flight of the Starliner spacecraft next month, but on Wednesday they announced the mission will now take place no earlier than Friday, July 21.

“While the Starliner spacecraft build is complete, additional time is needed to close out verification and validation work prior to the system’s first flight with crew on board,” Boeing said in a statement posted on its website.

See Mars’s beautiful Jezero Crater from the air in flyover video
Still from the video of Jezero crater created by merging data from various Mars orbiting spacecraft.

If you're feeling in need of some travel to broaden your horizons but you don't have the option to leave home right now, the European Space Agency (ESA) has something special to offer you: A virtual flight over the famous Jezero Crater on Mars.

The video, created using computer simulations from data collected by ESA’s Mars Express and NASA's Mars Reconnaissance Orbiter, begins in orbit and shows a soothing swoop down to Jezero's location, before switching to a point of view slightly above the surface to show you the view of the crater from above. First you see a pan around the entire crater, then the video goes closer to show the features of the crater in more detail.
