FleshJeb Posted March 7, 2023 Share Posted March 7, 2023 I just managed to catch the beginning. Shame about stage 2, but that dogleg was nuts! They'll get it next time. Quote Link to comment Share on other sites More sharing options...

YNM Posted March 7, 2023 Share Posted March 7, 2023 Welp, sadly the 2nd stage didn't light up at all. Looking back in the stream at the 2nd stage sep/engine ignition point, the commentators (?) knew it went wrong as well I think. They mentioned they were glad it launched but since it fails mid-way they can't say it's a success. Quote Link to comment Share on other sites More sharing options...

I think it shouldn't be the first one and definitely won't be the last one Quote Link to comment Share on other sites More sharing options...

SunlitZelkova Posted May 1, 2023 Share Posted May 1, 2023 A new sample return mission has been proposed, utilizing technology from Hayabusa 1 and 2 (Hayabusa3?), but for a comet this time. It will launch in the mid-2030s and the sample will be returned in the 2040s, and will consist of a mothership with a deployable probe for the sample return itself. The target comet lies between Earth and Jupiter. It will be able to analyze the samples on its own instead of having to wait until the capsule is returned to Earth. https://www.japantimes.co.jp/news/2023/04/30/national/science-health/jaxa-new-hayabusa-mission/ (might be paywalled) Quote Link to comment Share on other sites More sharing options...

It looks a bit like the Mockingbird 'brick-lifter' SSTO. Chances are good. A quick MT of the post says they're proposing propulsive landing on non-atmospheric sites, and looking in to decelerating and even augmenting propulsion with the atmosphere.

steve9728 Posted July 17, 2023 Share Posted July 17, 2023 It's many times less impactful than I thought it would be. Plus, the fact that no one was hurt, and it exploded in a ground test - that sounds like good news to me: much better than going up in the air and exploding. As long as they learn the lessons from this. Quote Link to comment Share on other sites More sharing options...
SunlitZelkova Posted August 21, 2023 Share Posted August 21, 2023 https://x.com/slim_jaxa/status/1693415421972730055?s=46&t=Jd73T2beq0JLNtwTy1uR5A Slightly old tweet. It is now 4 days until the lift off of SLIM (Smart Lander for Investigating the Moon). SLIM will ride share with XRISM, an X-ray telescope. They are launching on an H-2A, not an H3.

SunlitZelkova Posted September 2, 2023 Share Posted September 2, 2023 So in a thread in the lounge I mentioned I was going to visit the JAXA Tsukuba Space Center, but we had a change of plans and ended up going to the Chofu Space Center in Tokyo! Here are the pics. This is the outside of the facility. It is the HQ of JAXA and is the location of some test facilities. The main attraction on display at Chofu is AFLEX, one of the test articles used during the H-II Orbiting Space Plane program in the 1990s. Here's a cutaway of the different parts. And here is a depiction of the test flight profile. Also on display were a number of models of JAXA's past and present fleet of flying testbeds. As you can see, this one was utilized for VTOL research in the early 1970s. The center had a number of different concept art on display of their current development projects. I don't want this post to be too long so I will post them in a few days. The center was small, but great fun to visit. They had some kiddie displays showing off how jet engines and wind tunnels work, and although it was closed on the day I went there, there was a spaceflight simulator too.
