Inspector Smile is ready for science! 🫡 This is Smile’s first ultraviolet view showing an auroral substorm. With the ultraviolet camera now operational, Smile becomes the first spacecraft since 2008 to capture the full ring of northern lights around the north pole in ultraviolet light. 🔭 🧪 ☀️

A ‘Juice eye view’ of our home planet 🌍 On 28 September, our Juice mission completed a gravity assist flyby of Earth. As Juice flew just 8640 km above the Indian Ocean, it snapped a series of images with its onboard monitoring cameras, giving us these unique views 👇 youtu.be/zmW8hgV39IU 🔭 🧪

The real reason for the multiple Earth flybys of the (forgetful) ESA Juice spacecraft 😜. xkcd #3304: Jupiter Icy Moons Explorer @science.esa.int www.explainxkcd.com/wiki/index.p... #PlanetSci
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.

Title text: "I did briefly visit Venus in August 2025, but I figured out the mistake on my own because it didn't have any moons."

The bonds between Star Trek and NASA. 50 years ago, on Sept. 17, 1976, NASA rolled out its first space shuttle in Palmdale, CA. It was named Enterprise, thanks to a massive write-in campaign by Star Trek fans. Check out this thread for more - fosstodon.org/@AkaSci/1172...
