@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.

@drnereide.bsky.socialYou are looking at the dunes of Endurance Crater on #Mars, in this approximate true-color panoramic camera image, highlighting the reddish-colored dust present there.
What a fascinating geological phenomenon!

![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.

@stim3on.bsky.socialI hinted that there would be more images from the Juice flyby, so here is the timelapse of the full event!
It's always amazing to get these views of our fragile Blue Marble from the spacecraft we send out to explore the solar system!

@ita.esa.intOggi, la sonda Juice è passata a soli 8.640 km sopra l'Oceano Indiano e ha ripreso delle immagini con le telecamere di monitoraggio di bordo.
1️⃣Africa, ripresa dalla telecamera di monitoraggio di Juice
2️⃣Madagascar, ripresa dalla NavCam di Juice
3️⃣Luna, ripresa dalla NavCam di Juice

@stim3on.bsky.socialGreat day here at ESOC, staying in the control room with the team while the images came down and processing the JMC images.
Earth proved to be a real stunner with Africa and Madagascar in full view.

@science.esa.intA successful Earth flyby improves Juice’s course to Jupiter
Earlier today, Juice flew just 8640 km above the Indian Ocean and snapped these images with its onboard monitoring cameras.

@drspacejunk.bsky.social'And why should something be assessed only for its benefits for us? This is such a narrow way to look at the richness of off-Earth environments, and one I’m deeply uncomfortable with'.

@drnereide.bsky.socialThink you know Jupiter? In ultraviolet light, it can look like almost another planet.

@stim3on.bsky.socialComing up tomorrow, ESA's Juice spacecraft will fly past Earth for another gravity assist!
I had the fantastic opportunity to help planning the JMC shots this time around. We're trying a bunch of new things with this camera, so I'm really excited to see how they'll turn out.
