A fun fact related to this- the first launch of *a* Japanese person in space was not an astronaut, but TBS (Tokyo Broadcasting System) reporter Akiyama Toyohiro. He flew on Soyuz TM-11 to Mir in 1990.

If mean the citizenship, rather than the ethnicity.

Soyuz-Dragon crew exchange program participates selected, but list will be kept under the table for now because the dates aren't properly fixed.

OK, so I was checking with one of the r/EnoughMuskSoam types on Twitter and... So, you remember Makeyev's Korona hydrolox SSTO? Well, apparently, they've been able to arrange for a university research program into both an alcohol-oxygen aerospike and the liquid hydrogen-comlatible composites. That's their engine testbed.

Is that braided metal tubing a repurposed toilet tank fill line? That would make a great addition to the legendary shower head fuel injectors. 

Anyways, cool stuff. I love aerospikes.

Korona

Nice sense of style.

A sanitizer-fueled rocket.

Always neat to see a fresh new Soyuz!

Satellite devris to pass by the ISS in 32 minites. All personnel instructed to take shelter inside the ships or the American segment... which is debris-immune? Or is the Moscow MCC not allowed to boss the Dragon crew around?

20 minutes till we can know if we have an ISS.

Possible ASAT test may have caused a debris field. Few unconfirmed details:

Interesting, what kind of rocket was used. If it was indeed an ASAT test, and not the satellite just breaking up by itself.

It's a part of the Earth defense from NEO in LEO.

A big leap at this point, with strong inentives for both saber-rattling and fake news. I'm at least waiting for someone to check if it's in the probable engagement basket for known sites (Plesetsk, Kapustin Yar). After the Chinese HGV equine excrements spectacle I'm willing to risk having to eat my words.

On this day in 1988, the USSR launched Buran on its only test flight. Just kinda cool.

Apparently, the launch from Plesetsk was detected early in the morning.

The target satellite was in 500km orbit, just above ISS, so the cloud of debris will rain through ISS orbit on their way down. Cosmonaut job got much more exciting. Fun guaranteed!

Yeah, expect the current Fengyun-1C flybys to get mixed in with that. The timing is rather convenient.

I'd say we have a pretty solid case here:

For the benefit of everyone involved, Ikar №39 is the civilian cover name of the satellite. We don't have a third hazard in play.

Really wondering why they cast excrement on the fan like that, and whether this was impromptu or not. India at least pretended to make steps towards debris mitigation.

US and UK have confirmed it was an ASAT test, and released statements condemning the test

This is what I'd call a hot take;

Probably because they needed to do a live test of Nudol, and potential debris were of little importance to people who run ASAT development.

But on the bright side, as we can clearly see, the test was successful. So no new tests are needed, right?

Looks like this sort of stuff https://www.mcmaster.com/tubing/minimum-temperature~range~~-2114868771616/minimum-temperature~range~~-2115472751408/liquid-nitrogen-hose-with-threaded-fittings/

Probably the toilet tank version is not cryo rated or high pressure rated.

If I present my comments in the language they are streaming from me right now, I'll get banned from the forum. *deep breath* This was among the most irresponsible things done in space in the recent history, maybe all of history, of space flight.

Keep in mind that general vicinity of debris cloud from 500km impact is guaranteed to cross paths with ISS eventually as their orbits degrade. The odds of an actual impact are still on the low side, and since larger debris are tracked, ISS will likely be moved to avoid the highest risk areas, but the odds that ISS crew will have to deal with puncture holes in the hull in the next few years has gone up by orders of magnitude from this event alone.

Maybe to study well how to avoid the Kessler syndrome in LEO.
Say, to keep the foreign sat networks safe in case of asatting, to let the worldwide communication and navigation work.
What if several clouds cross the Starlink/OneWeb orbits?

Shooting down a satellite have many similarities to shooting down, say, a FOBS...

What a nonsense.
FOBS is just putting in LEO and deorbiting, not a kinetic intercept.
Or if he means the FOBS intercept, then it's much easier than a ballistic intercept, as FOBS moves predictably.
The whole FOBS theme is really pulled by ears here.

Well of recent history I agree, but else you're underestimating the 60s. The USAF once sent a few thousand needles in LEO just cause, and remember the "nuking the moon" plans too

That's like saying "I want to study what being shot feels like, so I'll shoot myself in the leg"

I think it’s a good possibility. A test to make sure they can intercept a FOBS while it’s in orbit.

Question is, whose FOBS?

 

China is presently making non-statements on the above happening. We also have a semi-official vapid denial from a deputy head of Duma armed forces committee.
