Is SpaceX using recycled rockets? They have in the past. https://latechnews.org/spacex-launches-bulgariasat-1-recycle... Government is normally getting in the way or at least slowing down the process of innovation. Hopefully that doesn't happen here at to much a cost to SpaceX and the U.S. tax payers.

This is the first launch of their heavy rocket according to the article so nothing to recycle yet. The government is one of spacex’s biggest customers.

Er, 2/3 of the first stages are reused, and the unusual thing about SpaceX is that they have a lot more non-government business than any US launch provider ever.

When was the launch supposed to take place?

Static fire was planned for today. Date for an actual launch hasn't been set yet, because a successful static fire (or several) has to take place before that. SpaceX is taking their time to extensively ground test this one, because the Falcon Heavy has never flown before, and is a significantly more complex rocket than the proven Falcon 9 (27 engines need to ignite at launch vs. 9, plus the booster attachments have never been tested before).

I think this is what the parent comment is referring to: https://en.wikipedia.org/wiki/Baikal_(rocket_booster)

Never took off. Never went to the prototype stage even. All they made was a mock-up. Plus he's talking about 70's and 80's, whereas that mock-up was made in 2001.

The point is that the idea itself isn't new, but space tech has been stagnant for decades before a company like SpaceX appeared on the scene

Different solution: Just use the browser that came with the OS. Works perfectly in Safari.

I can't use Safari until I reboot to install a critical security update. Yeah, no, I have a lot of ssh sessions open. And how is it possible that a browser on Unix requires a reboot to update?

That's what tmux and screen are for. Windows 10's infuriating restart requirements don't affect my ssh sessions.

This is easily blamed on the shutdown, but it isn't that simple: Falcon Heavy static fire has been postponed numerous times. On Tuesday (Jan 16th), it was cancelled once again, but with no new target test date. That indicates that SpaceX is still working on the rocket/pad. I didn't find information on when they'd be ready again, but blaming a delay on Falcon Heavy's static fire test on the Government Shutdown is only…

They did go through with a Wet Dress Rehearsal on Saturday, though, which already validates many things just prior to engine ignition. So if they were confident to continue with a static fire on Monday and there were no other issues known I'd say it's fair to blame it on the shutdown. Of course, more issues could arise during the test, but we won't know now.

Isn't it generally a bad idea to rely on everything (power, network, OS) to remain stable to keep an SSH session open, just so processes on the other end don't get terminated?

Shutdown started at Midnight Friday though didn't it?

Yes, that's what tmux and screen are for. You run one of them on the server and work within it, and then it doesn't matter what happens to the client or connection, your server processes are fine.

No, the original comment claimed that the USSR boosters we're designed to glide and land, which they never were.

And rockets landing and taking off many times is a very old idea, also not invented in USSR in the 70's.
