NASA's Perseverance Mars Rover

In a research article [...] a team led by Brian Jackson (Boise State University) described how they used information from Ingenuity to measure the speed and direction of Mars’s winds.

Previously, Jackson had carried out field experiments on Earth with a small drone to show that wind parameters could be extracted from an aircraft’s attitude data. Building on that proof-of-concept study, Jackson’s team used models to understand how Ingenuity’s attitude would change in response to winds of varying speed and direction.

The team calculated wind speeds ranging from 4.1 to 24.3 meters per second [...] Compared to meteorological models, the measured speeds tended to be higher than expected and the wind directions did not always match. These differences might reflect the influence of localized geological features, like craters and scarps that whip the wind in highly variable directions, that the models do not fully capture.

Jackson’s team found it unlikely that the higher speeds measured at Ingenuity’s higher altitude were the result of random fluctuations; instead, they proposed a physical explanation rooted in the aerodynamic conditions upwind of the rover and helicopter.

Accurate measurements of wind speeds on Mars can help scientists investigate our neighboring planet’s surface processes and dust transport, as well as help to plan safe entry, descent, and landing for future missions.

erseverance rover acquired this image using its onboard Right Navigation Camera (Navcam). The camera is located high on the rover's mast and aids in driving.

This image was acquired on Jan. 28, 2025 (Sol 1401) at the local mean solar time of 16:11:43.

First coring attempt since sol 1215, when Perseverance was still down in Neretva Vallis (~6 months ago). That attempt was clearly successful on the first try, as this MastCam image from that date readily showed. Here's a shot taken from the same angle on 1401, with no sample apparent in the tube.

It's worth recalling that this target proved to be very friable (prone to crumbling) the last time Percy interacted with it, when the sol 1375 abrasion patch was made earlier in January.

The science team must really want a sample of this stuff! I am very much looking forward to the next mission update!

The new location is overlooking an earlier abrasion patch at site 64.2278 that the rover reached back on sol 1363.

The attached image is a very roughly processed cropped mosaic using six L-NavCam tiles from some post drive images.

The mosaic highlights some of the recent rover wheel tracks as it continues its exploration outside Jezero crater.

Dust devils in Arabia Terra - Perseverance NavCam - Sol 1398

This enhanced processing of Navcam Left images shows several dust devils moving across the floor of Arabia Terra, just outside of Jezero crater.

The largest dust devil in the foreground is at least 300 meters high (328 yards).

The largest dust devil starts at the edge of the crater which is located 1 kilometer east of the rover’s location (~5/8 mile)

For scale the crater floor viewed from this direction is close to 220 meters wide (722 ft)

The original sequence lasts about 2.5 minutes, and was taken around 12:26 local mean solar time.

This is a reduced resolution version of the animation by Simeon Schmauß.

In this GIF, I see three dust devils, it looks like there are at least 4 in the full size (uncropped) version on Flickr.

The video has a fair summary of recent work by Perseverance, and a suggestion as to why the rover may have turned around to climb back uphill.

(The latest abrasion patch was more interesting than Mars Guy lets on in the video, but it's worth a watch nonetheless)

Walkabout: A long drive on sol 1397 (January 23, 2025) takes Perseverance back to a location overlooking site 64.2278.

It reached that site back on sol 1363 (December 20, 2024), spend the rest of 2025 there and even performed an abrasion there.

Just making a thread for anyone who wants to commiserate about the lack of new images from Percy of late. Mods, feel free to delete if this doesn't belong here.

We shouldn't ever forget that many many JPL employees have lost their homes, which is more than just a "bummer". They might be launching their stuff into space, but the work of people at the lab is appreciated and its absence is felt in people's daily lives too.

Not my best work. tried to edit in further coverage, but it isn't truly seamless.

Mars Guy Episode 197

The wildfires burning in the Los Angeles area have been devastating to those in its path, including the community adjacent to the Jet Propulsion Laboratory. The consequences of this tragedy have now reached all the way to Mars.

A link to the Caltech and JPL Disaster Relief Fund is included in the video description.

The fires that spread destruction across the Los Angeles region this week and killed at least 11 people have spared two famed scientific facilities: NASA’s Jet Propulsion Laboratory, which has spearheaded planetary missions and astronomy efforts, and the historic Mount Wilson Observatory. While the Eaton blaze that has destroyed nearly 14,000 acres and 7000 buildings in Altadena and Pasadena stayed an appreciable distance away from JPL, flames from that fire continued to climb towards Mount Wilson until eventually stopping at the edge of the observatory’s grounds on 9 January.

“Thanks to the efforts of our firefighters and observatory staff, no buildings or infrastructure have been destroyed” at these facilities, said Anthony Marrone, the LA county fire chief, in a press briefing this afternoon. Still, JPL director Laura Leshin said on X that more than 150 of her staff have lost their homes to fire. And some Mount Wilson employee have evacuated and don’t know when they can return. “For us, the story is about our employees, and not about the facility” says Veronica McGregor, a spokesperson for JPL.

In preparation for the Eaton fire, one of six scattered across Los Angeles, JPL moved operations of its Deep Space Network, an international network that commands and communicates with space-based missions, to a back-up operations center and instructed all employees to work from home.

We have to expect reduced commanding of the rovers and associated downlink of new images

Text:- JPL to Remain Closed Until Monday, January 13 2025

Posted on January 08, 2025 at 11:51 AM

The Jet Propulsion Laboratory is within the mandatory evacuation zone for the Eaton Fire and is closed to employees and visitors on Wednesday, Jan. 8. The laboratory will remain closed until Monday, Jan 13. Additional updates on the Laboratory’s status will be posted on this site (emergency.jpl.nasa.gov).

Currently, JPL facilities, labs and hardware are secured and protected. Deep Space Network operations, normally conducted at JPL, have been moved offsite to a back-up operations center.

As of Tuesday night, employees were directed to work from home, with only a small number of critical personnel on-site Wednesday morning. Our Protective Services Department is maintaining constant communication with the Eaton Fire emergency command center, and the Laboratory is currently receiving assistance from the LA County Fire Department.

Also on Tuesday night, the mesa above JPL was made available to support firefighting helicopters; however, flights were cancelled due to high winds. The mesa remains available to assist firefighting efforts aimed at protecting nearby neighborhoods and JPL itself.

The safety of our employees is our top priority. We also keep our neighboring communities—many of which are home to our employees and their families—in our thoughts as they endure the challenges and devastation of this fire.

A 136 meter (446 ft) move to the West for Perseverance rover, its the first drive of 2025, includes a record 34.15 m (112 ft) move downslope on mission Sol 1380 (January 6, 2025).

The first signs of the cataclysm that formed Jezero crater started to appear on the long drive by Perseverance up its rim. Now on the other side, Perseverance is encountering rocks clearly formed in the fiery aftermath of a giant impact event.
