Scotius Posted September 20, 2021 Share Posted September 20, 2021 There is difference between an orbiter and helicopter drone. Orbiter is much less likely to crash and scatter across the landscape. Quote Link to comment Share on other sites More sharing options...
kerbiloid Posted September 20, 2021 Share Posted September 20, 2021 Actually, currently the only function of a drone is to test a drone. Quote Link to comment Share on other sites More sharing options...

The difference is one will rip 500 million dollars out of the rest of the robotic space program and one is possibly one of the cheapest planetary spacecraft in history. 30 minutes ago, kerbiloid said: Depends on the empire.

I myself thought the photo was unnecessary, but here it is! The chair appears to be specially designed to avoid making them look like they are being carried in the manner injured (and thus weak? In the view of propaganda...) people are. A marker has been erected at the landing site. Within the square they targeted, the landing was dead center. This makes me curious about modern Soyuz accuracy. Edited September 23, 2021 by SunlitZelkova Quote Link to comment Share on other sites More sharing options...

SunlitZelkova Posted September 29, 2021 Share Posted September 29, 2021 First time a crewed spacecraft has been propelled by something other than chemical rockets, even if it is just for station keeping. The Zhuhai air show yields lots of juicy info for not only space, but also China's armed forces and export military equipment. Models of the LM-5DY and LM-9 were on display as well. Remember the spaceplane that had a suborbital flight test of the second stage some months ago? I posted an artist's concept when I posted the news, but the definitive look is now known. A video presentation was shown which included an animation of it docking with a space station, so the designer's may have Tiangong resupply in mind for a future mission. The Long March 8 (CZ-8) is China's government developed Falcon 9 counterpart (partial reusability). Quote Link to comment Share on other sites More sharing options...

That's an X-37B riding a Spiral. And that thing in the back is a dead ringer for Kalibr UKSK. Not many ways you can make a 533 mm VLS ) Quote Link to comment Share on other sites More sharing options...

They forgot to copy the two-staged hydroflu or how is hydrogen+fluorine called like "hydrolox" for H+O booster for the upper stage from the original project. The plane is not enough.

SunlitZelkova Posted October 13, 2021 Share Posted October 13, 2021 (edited) Mission profile of China's asteroid sample return mission, which will launch in 2024. It is currently being referred to as Zheng He, after the early Ming era maritime explorer. --------------------------------------- -------------------------------------- I think the Chinese commercial companies have a much better shot at nailing reusability compared to the government funded Long March 8R. Of course, I hope both will be successful, but not much visible progress has been seen on the LM-8R and I am a little skeptical of whether the "old space" ballistic missile manufacturers have the will to deal with the failures to eventually succeed.

kops said Posted October 15, 2021 Share Posted October 15, 2021 Looks like shenzhou 13 was successfully launched. Carrying one female astronaut and two male astronauts to the Tiangong space station. This mission looks like it's going to prove some sort of "fast docking technology", but it doesn't look like it's going to be that fast, six hours supposedly. I watched the whole launch live, and this time I can confirm it was real time. Quote Link to comment Share on other sites More sharing options...
SunlitZelkova Posted October 16, 2021 Share Posted October 16, 2021 Crew is as follows- Commander- Zhai Zhigang (PLA Strategic Support Force Major General, became the first Chinese person to walk in space in 2008) Operator- Wang Yaping (PLAAF Colonel, deputy of the National People's Congress, second Chinese woman in space, visited Tiangong-1) System operator- Ye Guangfu (PLAAF Colonel, first spaceflight) More pictures from the launch- Spoiler 14 hours ago, kops said said: Looks like shenzhou 13 was successfully launched.

I watched the whole launch live, and this time I can confirm it was real time. Six is considered fast. Soyuz used to take two days to dock with the ISS but the 6 hour docking flight profile first used on Soyuz TMA-08M is referred to as a "fast rendezvous and docking". Soyuz MS-17 used an "ultra fast" rendezvous and docking profile, docking in 3 hours. Quote Link to comment Share on other sites More sharing options...

It's counting from about T0, probably. I'm not aware of the official designation of ultra fast rendezvous and docking profile. But I think the theory that he defined helped me a lot.

I’m not sure if it is official (present in actual documents and so on) in that sense of the word, but both NASA and Roscosmos have used those two terms in their PR.
