#tianwen2 — Public Fediverse posts

For the asteroid crowd:

Is anyone aware of any new results to be released from #Tianwen2 at #Kamoʻoalewa?

We are entering the period where the asteroid will be closest to Earth while the spacecraft is there; so downlink will be easiest.

@AndrewJonesSpace ?

Three more views of asteroid (469219) Kamo`oalewa from #Tianwen2 have surfaced, also from early July as the first one published (included here at lower left) - no mission updates since: https://bsky.app/profile/chinaspace.bsky.social/post/3mu7trl3sqc2y

A China deu início à exploração científica do asteroide Kamo'oalewa com a missão Tianwen-2, que alcançou o corpo celeste após percorrer cerca de um bilhão de quilômetros. A sonda se aproximou a aproximadamente 20 quilômetros do asteroide.

💁🏻‍♀️ TIL: 🛸☄️ #China’s Tianwen-2 probe has captured the first close-up image of Kamoʻoalewa, a rare quasi-satellite of #Earth, from about 20 km away.

The mission, which launched in May 2025, aims to collect samples from the 40 to 100 meter wide #asteroid to study its composition and origin. Scientists hope to determine if the minimoon is a fragment of our own #Moon.

Based on the official Tianwen-2 image, 469219 Kamoʻoalewa appears to be only around 20–30 m across in the line-of-sight view. If correct, it would rank among the smallest natural objects ever visited by a spacecraft...

🤩 image drop from Chinese Space Agency asteroid sample return mission #Tianwen-2 (Heavenly Questions-2)! It's now orbiting Kamoʻoalewa, just 18m across, looking for a place to land, drill, & return 100g back to Earth to see if this is a missing piece of the moon. Then it goes on to a comet 😮🧪🔭

This is the *other* #asteroid visited by an Asian spacecraft this month: tiny (469219) Kamo`oalewa - the bar measures 10 meters - as seen by China's #Tianwen2 from 20 km distance ahead of a #SampleReturnMission: https://www.facebook.com/Spacewalk2021/posts/pfbid02JKYdMnWPGRxxShDj6U6d6M2vs5qUkVL55v97CBgAHJ6KTnCvM6TkSTyDVEFGqk23l (see also the paper https://arxiv.org/abs/2606.24017 about JWST observations of the asteroid).

Kamoʻoalewa is an #asteroid ☄️ between 40 to 100 meters across. China’s #Tianwen2 spacecraft has arrived on July 4 to collect samples for return to Earth. #Tianwen3, scheduled for 2028, will collect samples from #Mars and deliver them to Earth https://www.forbes.com/sites/jamiecartereurope/2026/07/04/a-chinese-spacecraft-just-arrived-at-earths-quasi-moon/

Bizarrely European amateur radio tracking with the big dishes in Dwingeloo and Bochum - https://bsky.app/profile/radiotelescoop.bsky.social/post/3mnqzh2kzfk2x - remains the only indication that China's #Tianwen2 has reached its target asteroid (469219) Kamoʻoalewa: https://www.scientificamerican.com/article/chinas-tianwen-2-spacecraft-arrives-at-one-of-earths-mysterious-quasi-moons/. Bochum also reports that the data rate has gone up: https://bsky.app/profile/amsat-dl.org/post/3mnxqa7bshk2s

It looks like China's #Tianwen2 will reach asteroid (469219) today to begins its sample return mission - this follows from radio tracking by amateurs in Dwingeloo and Bochum: https://bsky.app/profile/radiotelescoop.bsky.social/post/3mn5aqlk3222l and https://x.com/amsatdl/status/2061787339936973154. And radio hams are also decoding the telemetry: https://destevez.net/2026/05/an-update-about-tianwen-2-telemetry/. While the paper "Tianwen-2 mission target asteroid (469219) Kamoʻoalewa probably develops an Itokawa-compositional but more space-weathered surface" - https://www.nature.com/articles/s41467-026-73284-w - calls the proposed origin of the asteroid from the Moon into question.

🛰️☄️ La sonde chinoise #Tianwen2 qui a décollé le 28 mai 2025, devrait effectuer dans les heures à venir une insertion en orbite autour de l'astéroïde Kamo'oalewa. On attend la communication officielle.

We are tracking #Tianwen2 these days. The Chinese probe is on its way to study the near-Earth asteroid Kamo'oalewa. The exact trajectory of Tianwen-2 is not public, so we had to search around Kamo'oalewa. It helps that the radio signal of Tianwen-2 is very loud. With the narrow beam of the Dwingeloo radio telescope, we can pinpoint Tianwen-2's position to about 0.1 degree.
