@drnereide.bsky.socialPerseverance rover has broken the off-world driving record.
On 11 Oct. 2026, it reached 45.22 km on Mars, surpassing Opportunity’s 45.16 km.
It hit the mark in 5½ years, compared with nearly 15 for its predecessor, on the 2,006th sol of the mission.

@science.esa.int🌍South Africa has the famous Table Mountain..
🔴Mars has Amazonis Mensa, which is three times as high!
And can you spot the ancient lava flows?

@elevenpointtwo.bsky.socialDid Viking find microbes on Mars in 1976? It seems likely.

![ASU Think Beyond Webinar: Did Viking find microbes on MArs in 1976? It seems likely.
Following the Viking 1976 mission, Robert Jastrow, then Director of NASA’s Goddard Institute for Space Studies, concluded that “[s]hort of seeing something wiggling on the end of a pin, the case for life on Mars is now as complete as the Viking experiments could make it.” However, because the Viking team failed to properly understand organic chemistry, it misinterpreted data from a gas chromatograph-mass spectrometer (GC-MS), leading to the conclusion that, not only was no Mars life detected, but that life was in fact impossible there due to the reactivity of the soil. This monumental blunder entered textbooks, NASA reports, National Academy Decadal surveys, DARES workshops, and NASA peer review. Even though my laboratory explained in 2000 that the GC-MS data had been misinterpreted, and Rafael Navarro-Gonzales in 2010 provided a complete analysis of what went wrong, the Mars exploration communities continue to this day to mis-direct resources relevant to Mars astrobiology in research programs, funding priorities, and leadership. This talk will detail this history as an excellent teaching example to show students how confirmation bias, group think, and "community consensus" damages high stakes science.](https://cdn.bsky.app/img/feed_fullsize/plain/did:plc:6oscxlepvt6x6xf5z2frsc5z/bafkreifvvubbkycwx2nrlsglttterikckzhc5pxqiu6276nx3onku2mfeu@jpeg)
@leighfletcher.bsky.socialI'm looking for a new #postdoc to join Leicester's #planetsci atmospheres team, working with us on the treasure-trove of #JWST giant planet data to study atmospheric composition, weather, and variability. Deadline Nov 5th with a start date in early 2027.
@akasci.bsky.socialMars rover Perseverance finally made a move today to set a new record for the distance traveled by a rover on a distant planet - 45.22 km.

@drspacejunk.bsky.socialUpcoming missions to Venus position the search for volcanic activity as a key goal, but could we actually see volcanic eruptions if they occur?

@drnereide.bsky.socialHistoric view of Jupiter’s volcanic moon Io.
The red dot is glowing magma at the Tvashtar eruption site; the blue plume is fine dust particles lofted hundreds of km high and catching sunlight.
A rare, detailed look at Io’s extreme activity from New Horizons’ Jupiter flyby.

@erickmandt.bsky.socialI am admittedly very biased here, but please take a look at pages 46-48 for info on a very impressive scientist (and my wife) Dr. Kathleen Mandt. She brings a refreshing dose of common sense and kindness to the science community. #planetsci #viper
@drkeithsmith.bsky.socialThe Martian Moons Exploration (MMX) spacecraft will retrieve two samples from Mars' moon Phobos, then bring them back to Earth for lab analysis. In a feature-length article, @squigglyvolcano.bsky.social previews the mission, due to launch on 20 Oct. ☄️🔭🧪🛰️ #planetsci

@drspacejunk.bsky.socialAre we ever going to terraform anything and why is everyone so fixated on Mars?

@drspacejunk.bsky.social290. By 1962, people were already thinking about what resources - such as water - the Moon might have to sustain human habitation and make fuel for solar system exploration.

![4 panel comic -
[Panel labeled "April 2023". Earth is shown, and the JUICE space probe is flying away from it, with dotted lines showing its path since liftoff.]
Mission Control: We have liftoff!
Mission Control: JUICE is en route to explore the icy moons of Jupiter!
JUICE: Wheee!
[Panel labeled "August 2024". Two images of JUICE are shown, with dotted lines showing its path through space. One is to the left of Earth, the other to the right, and the path goes below Earth.]
JUICE: ...So which planet was I visiting again? I got distracted.
MC: Jupiter!
JUICE: Right, OK.
[Panel labeled "September 2026". Two images of JUICE again, this time the path goes above Earth.]
JUICE: Is Jupiter the one with all the rings? Or...
MC: No, the big one near it.
JUICE: Got it!
[Panel labeled "January 2029". JUICE is approaching Earth from the left.]
JUICE: And which moons am I looking at?
Mission Control 1: Oh my God.
Mission Control 2: Now I get why we budgeted for so many Earth flybys.
