Model of fully reusable Long March 9 at Zhuhai Airshow, to be powered by 30 FFSC methalox engines, each provides ~200t thrust with 341s impulse and 18MPa chamber pressure. https://t.co/2b7LYG3MUu

@TMFAssociates @QuiltySpace Could the coverage of China be a factor here? 🤔 Many airlines fly to & over Chinese airspace, and they may not like the idea of not having coverage in the area. On the other hand competitors like Panasonic & Intelsat have agreements with local operators for a seamless coverage.

Vous êtes vous déjà demandé comment fonctionnent les rendez-vous spatiaux ?
Comment Crew Dragon ou Soyouz arrivent à approcher tout doucement de l'ISS, alors que tout ça file à plusieurs kilomètres par seconde ?
Je vous explique les bases dans ce thread illustré: 🧵

@SpaceMoh @UniPadova This sucks, sorry this is happening to you 😔

[Jonathan McDowell @planet4589]

The X-ray microcalorimeter, developed by a NASA-GSFC-led team, is an amazingly sensitive device where the energy of an photon is measured by noticing the increase in temperature of the pixel caused by absorbing it! To do this, each camera pixel is cooled to 50 milliKelvin !!!

Here’s my latest infographic on Chinese commercial rockets and their engines. This should give a good idea of the new launch vehicles we can expect from China in 2023-2025.
A quick thread 🧵

Hey @John__Holst your piece on Arianespace raises a few interesting points. But there are some that are a bit biased I think. Allow me to discuss them.

@SegerYu 进展挺快的👍
文昌发射场附近可以允许飞无人机吗？

[Dongfang Hour @DongFangHour]

I'll be going live today at 14:00 UTC for the launch of the #Shenzhou15 mission! We'll cover the Shenzhou spacecraft, the Long March 2F, Jiuquan, and what to expect for the CSS in the coming years.
The link is available below 👇 See you there!

I'll be going live in ~1 hour's time for the launch of Mengtian! Lots of stuff to cover on the module itself as well as what the astronauts have been doing over the past several months.

@SegerYu Thanks for sharing this kind of old footage 👍 Fascinating

[Jean Deville @JeanHDeville]

@TechSpatiales @Kaynouky @chat_quantique @nicolas_pillet @DongFangHour Merci beaucoup @TechSpatiales ! Je vais essayer de faire un live similaire pour Mengtian 😊
ça serait avec plaisir de faire l'expérience d'un lancement de Longue March 5 ensemble. J'avais été à Hainan en 2019 (à Sanya, plus au sud), il y a vraiment de très belles plages...

[Jean Deville @JeanHDeville]

@byspto @raz_liu @spacestationguy @ChinaInSpace @SpokespersonCHN Nice shot! Congrats!

[Jean Deville @JeanHDeville]

@Siwelthelongboi @planet4589 The Xuntian space telescope will be launched on a long March 5B (2024-ish)

[Jean Deville @JeanHDeville]

@D_zongshi You wont regret it! I have the Sony 70-350mm and it already provides really good results
