MMX aims to bring at least 10 g of Phobos back to Earth, gathered with two samplers onboard the spacecraft. C-SMP will 'core' out a sample from 2 cm below the surface, while P-SMP (pneumatic) will collect material using a small whirlwind of nitrogen gas.

ONE WEEK UNTIL THE LAUNCH OF MMX! 🚀 There is some subtle messaging at the station closest to the JAXA Sagamihara campus.

A row of launch posters runs all the way along the wall above the train station ticket gates.

Phobos orbits only about 6,000 km above the surface of Mars, closer to its planet than any other moon in the Solar System.

I love that title!

🥔 Potato incoming!

MMX (Martian Moons eXploration) is a JAXA-led sample return mission to Phobos, the larger of Mars's two moons. The spacecraft aims to explore Phobos from orbit, land on the moon, scoop up a sample, and bring it back to Earth. 🕸️

It appears my astro-arch-nemesis, Phobos (along with accompying potato rock, Deimos) now has a voice on the website known as The BlueSky.

Follow @showmethepotato.bsky.social if you want to also have a love/hate relationship with these cursed Moons of Mars!

Upcoming JAXA mission to them in a week!

@elizabethtasker.bsky.socialOct 12, 2026, 4:28 AM

😂 I'm actually testing a MMX fact bot, that should give you a fun MMX/Phobos-related fact within about 20 minutes of you asking... but it's being a reluctant replier!

@elizabethtasker.bsky.socialOct 12, 2026, 3:43 AM

10 DAYS UNTIL THE LAUNCH OF THE JAXA MARTIAN MOONS EXPLORATION (#MMX) MISSION! 🚀🛰️ It's a place of evil, but the MMX account has been posting these cute countdown videos every day on twitter (and also instagram and threads, for a different brand of evil). The model in the background is Hayabusa2!

Well, good morning.

O Romeo, Romeo! #CapserCat has gone on a bold spree this week, and approaches my desk while I’m at my computer. It’s only because he wants to gaze adoringly at #NorahNeko but I’ll take it 😹

A fluffy black and white cat sits on the floor close to a large desk, looking up in a star struck manner. Above him, a calico cat lies on a cat bed attached to the end of the desk, looking down at him.
