All the things the Perseverance rover has achieved in its first year on Mars

It’s been one year since NASA’s Perseverance rover made its remarkable landing on Mars. Twelve months on, NASA has shared a roundup of all the achievements the rover has made in its quest to understand the Jezero crater, where it landed, and in its quest to search for evidence of ancient life.

One of the rover’s major achievements was collecting samples of Mars rock, which proved tricky at first due to the rock being more crumbly than expected. However, despite the challenges the rover has managed to collect six samples so far which are sealed up in tubes and will be left on the planet’s surface for a future mission to collect and eventually bring back to Earth for study.

About 20 inches (50 centimeters) across on average, the boulders in the foreground are among the type of rocks the rover team has named “Ch’ał” (the Navajo term for “frog” and pronounced “chesh”).

“The samples Perseverance has been collecting will provide a key chronology for the formation of Jezero Crater,” said Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate in Washington, in a statement. “Each one is carefully considered for its scientific value.”

Another major milestone was achieved recently when Perseverance broke the record for the longest drive by a Mars rover in a single day. That record had stood for 17 years, set by the rover Opportunity, and Perseverance was able to best it by traveling 246 meters in a single Mars sol. The rover was helped in this by its AutoNav navigation software which uses maps of the Martian surface to plan out efficient driving routes.

The next challenge for the rover will be to collect two further rock samples from a set of dark rubbly rocks named “Ch’ał.” These could help to answer major open questions about the age of the Jezero crater, as current estimates are based on impact craters and scientists want a more accurate way to date the region.

“Right now, we take what we know about the age of impact craters on the Moon and extrapolate that to Mars,” said Katie Stack Morgan, Perseverance’s deputy project scientist at NASA’s Jet Propulsion Laboratory in Southern California, in a statement. “Bringing back a sample from this heavily cratered surface in Jezero could provide a tie-point to calibrate the Mars crater dating system independently, instead of relying solely on the lunar one.”

An illustration showing Earth-orbiting space junk.

Space junk orbiting Earth is a growing problem. Old rocket parts and decommissioned satellites are orbiting our planet at great speed, posing a threat not only to functioning satellites providing critical services but also to humans aboard the International Space Station and China’s own orbital facility.

The situation is made worse when the space garbage crashes into each other, causing them to break into smaller, equally hazardous pieces.

Perseverance rover catches footage of a dust devil on Mars
mars 2020 perseverance rover

Many of the weather events we experience here on Earth can be found on other planets too, and that includes whirlwinds. Several missions have observed small whirlwinds called dust devils on Mars, and the Perseverance rover recently captured footage of one such dust devil in action as it rolled across the martian surface.

The footage was captured by one of Perseverance's black-and-white navigation cameras, called Navcams, and shows a dust devil moving at a speed of around 12 mph across a regions known as the Thorofare Ridge. You can clearly see the dust devil as a white column moving across the top of the ridge in an animation posted by NASA's Jet Propulsion Laboratory, which manages the rover.

Dark matter hunting telescope Euclid has a problem with its guidance system
Graphic rendering of the Euclipd space telescope.

The European Space Agency's (ESA) Euclid space telescope, which launched in July this year to investigate the mysteries of dark matter and dark energy, has run into issues during its commissioning phase. Although the early calibration images looked good, since then the telescope has had problems with the instrument that helps it position itself by locking onto particular stars, called the Fine Guidance Sensor.

The Fine Guidance Sensor has been intermittently failing to lock onto stars, which is making it difficult to orient the telescope in the right direction. When working correctly, data from the Fine Guidance Sensor goes to the spacecraft's attitude and orbit control system which keeps it in the right orientation. However as this has not been working as intended, the commissioning phase for the telescope has been extended so teams can investigate the issue.
