What's on fire at the right edge of the frame at the end of the video? Some building?mfb said:Here is a video
After 10 minutes of googling, I have a guess that it's a "detanking flare".berkeman said:What's on fire at the right edge of the frame at the end of the video? Some building?
I saw yesterday that it entered orbit.mfb said:Beresheet is on the way to the Moon, the planned landing date is still April 11 (it will enter orbit April 4).

Looks amazing!
Japan's Hayabusa2 has shot an impactor on its asteroid.
News report
Hayabusa 2 will take more samples of the asteroid. If it is considered safe enough it will take them from this fresh crater - the impact exposed material that had been locked away for over 4 billion years.

Good luck with those! ...Borg said:NASA Invites Public to Submit Names to Fly Aboard Next Mars Rover.
I'm going! My wife doesn't know it yet but she's going too.
anorlunda said:The barge recovery method seems much less reliable than recovery by landing at the launch site. Is there a reason why they could not land all the boosters at Cape Canaveral?
Sorry, I'm not understanding this part. A thrust-to-weight ratio above 1 means it can hover, no? If you can accelerate straight up, why can't you hover? And a T/W ratio of 3 would give you more capability to hover and move sideways, it would seem, no?mfb said:Even a single engine gives the booster a thrust to weight ratio above 1: It cannot hover, it has to reach zero velocity and the right position just as it reaches zero height with the first attempt. With three engines it has a thrust to weight ratio above 3, that makes it even more difficult.

So it looks like it could not bear that re-entryHigh entry force & heat breached engine bay & center engine TVC failed
I've seen somewhere a list of options available for Falcon Heavy capabilities: in short, the further they are from 'all back to origin' the more load can they pack. In reusable mode they can do ~ 8000kg to GTO, while in full expendable mode it is above 25000kg... This mission was like a safe reusable mode for boosters and maybe-expendable for the center core.anorlunda said:Is there a reason why they could not land all the boosters at Cape Canaveral?
