火星衛星探査機「MMX」打ち上げ成功、おめでとうございます。 平塚の自宅から撮影した打ち上げの様子を8倍速にした動画です。 左側の離れていく点が1段目、右側のクラゲのような光が2段目です。 噴煙が少しずつ形を変えていく様子がよく分かります。

H3ロケット10号機による火星衛星探査機「MMX」の打ち上げ、平塚の自宅から観察できました。左側が分離直後の第1段、右側が燃焼中の第2段です。噴煙が太陽の光に照らされ、まるで彗星の尾のような姿でした。

We bounced a radio signal off Venus' surface! On 17+18 Oct the Dwingeloo transmitted and Astropeiler Stockert received the echoes, 42 million km each way. We decoded a 10-character message from the echo. And we're not finished yet: more echos on 24+25 Oct. camras.nl/en/blog/2026/earth…

Cosmos 2612 has been maneuvering closer to an ICEYE SAR satellite. Using OEL, I created these visualizations to help understand what’s going on. The animation shows a 3D RIC frame animation of the recent motion The second figure shows how individual parameters evolved over time. You can see that 2612 matched the orbital plane of the SAR satellite and closed the in-track separation. The third figure shows that between gaps in TLEs the motion of 2612 changes in an unnatural manner. This indicates that a maneuver occurred. The last figure shows 2D cuts of the 3D animation. What do you think it’s up to?

Newly-discovered asteroid 8NIQ001 approached from the daytime sky. It wasn't discovered until after a close approach of ~1000 km above the Arctic. The size of a compact car, it would have caused no damage had it hit. #astro 🔭

This video was presented at the NASA-USGS Offworld Resources Workshop. Every curve in it is a computed trajectory, not an artist’s sketch. 1: Asteroid material arrives at the Rim, about 1.5 million km out, on natural paths into orbits around Sun-Earth L1 and L2. 2: From the Rim, refined material coasts to the Moon on gravity alone (~40 days) and is captured. 3: A few m/s burn puts it on an Earth-Moon cycler, which drops packages onto other orbits along its route. The Earth-Moon system is threaded with natural routes like these. Find the right ones, and moving material around cislunar space costs tens of meters per second, not kilometers per second.

Two football fields. That’s roughly how close Otter Pup 2 is now regularly operating next to @GilmourSpace’s ElaraSat, fully autonomously. This puts Otter Pup 2 on a very short list of spacecraft in human history. This video was captured from just 200 meters away as Otter Pup 2 conducted close proximity operations around ElaraSat. Otter Pup 2 is capturing images like these and using them to track and predict the position and orientation of ElaraSat on an ongoing basis. We’ve gone from thousands of kilometers to hundreds of meters away, continuing to test, iterate and validate our technology along the way. And Otter Pup 2 is not done getting closer, as it continues its mission to make history.

New SNIFFLES research reports 2,345 satellite RF detections across 1–26 GHz, including unintended radiation in protected radio astronomy bands. The findings provide valuable context for my independent S-band observations of Starshield satellites. Links in 🧵⬇️

Roman’s marathon of testing continues while it zooms toward L2! The team aligned and focused the telescope’s optics and gave Roman’s primary instrument a meticulous “eye” exam. The results: Roman’s cosmic surveys will be even sharper than expected! 🤩 go.nasa.gov/3TREG4R

Peep our Elytra orbiter being assembled in the cleanroom 👀. This spacecraft is part of our Riders 2 the Dark mission — America's first mission to land on the Moon's far side. Without direct line-of-sight to Earth, communication on the far side is impossible without a relay. That's where our Elytra orbiter comes in 🛰️. Elytra will serve as a transfer vehicle and communications bridge between Blue Ghost and Earth, enabling critical science operations on the lunar surface and setting the stage for future missions.

Artemis III progress! 🚀 The rocket boosters have been stacked. Teams are inspecting the solar arrays and testing the spacecraft. The crew is continuing training for their upcoming mission to test lunar landers in low Earth orbit. All this and more has Artemis III on track for launch in 2027: go.nasa.gov/3W7jHeV

Lunar Outpost and @JHUAPL recently conducted integrated lander-rover FlatSat testing for the MAPP rover, which will explore Reiner Gamma during @Int_Machines IM-3 mission as part of the APL-led Lunar Vertex investigation. Testing covered the rover’s electronics, software & control systems.
