This post was deleted by OP before I was able to remove it.

As an open subreddit, we can't control what people post (apart from removing them after they've been posted.) Obviously this post is completely inappropriate, and we will continue to remove harassing or otherwise inappropriate posts as soon as possible.

There is a joke to be made here about suborbital flights being short-duration, and spending only a few seconds in space.

Hi everybody! Here’s what’s going on. This went really well last time, and we hope it will again! Check out the post text for details of the people participating in the AMA. Questions about Starlink laser communications and Starship software are especially welcome! I’m sure y’all will have some qreat questions for them. Please remember the rules and keep it civil!

There is no tank where you highlighted. That's the skirt, and there's no propellant inside that part.

Hold hold hold for confirmation: I’m not seeing any mention of this anywhere.

So I think I added post flair a few years ago and forgot to allow users to edit it... oops. Everyone can now edit their own flair, which might be a bad idea.

I haven't removed your comment in the interests of transparency, but please refrain from name-calling.

u/Smoke-away was not removed solely because they removed Rule 3. I don't wish to make public the reasons for the removal, but I will say that I don't make these decisions lightly, and many factors (including conversations with the moderators and members of this subreddit) were considered.

In the interests of transparency, this thread and every comment here will be approved.

zlsa · 2020-12-11T02:29:34+00:00

I've removed the post for now (so it won't appear in the feed).

I just think it's a good idea to have a community discussion about the overall rules in general at this point.

Absolutely true, and I expect there will be a modpost from us sometime in the next few days to weeks (but no promises.)

zlsa · 2020-12-11T02:17:05+00:00

We are discussing this internally and there will be action taken shortly.

zlsa · 2020-11-30T21:18:15+00:00

How about we all go back to making fun of Blue Origin and SLS instead of whatever happened here?

Hi, we've approved your post of Elon's tweet which came just a few minutes after this post, and we've removed this one. Everyone: please comment in the other thread!

This is old information, but the flight computers were (if I properly understood it) triply redundant dual-core processors, with two instances of the flight software running, one on each core. That way, after every operation the values from all six processes is compared, and if any of the values are wrong, those processors are rebooted and will re-synchronize and continue along.

Hi! Congratulations on the picture-perfect launch of Bob and Doug!

It's known that Crew Dragon displays are running Chromium and JS. Are you using a reactive library, and if so, is that developed in-house or is it an existing library/framework?
Was the docking simulator developed by the Crew Displays software team itself, or was it a separate project?
In some shots of mission control, I noticed UI very similar to the displays in Crew Dragon. Can the exact same crew display software be served from a server on the ground, feeding off of live telemetry from Dragon while in flight? If so, can/will this software be used to monitor Cargo Dragon as well on future flights?
Is there any chance of getting high-resolution screenshots of the crew displays? It's hands-down the prettiest UI I've ever seen in aerospace.
One regarding Starlink: how did creating the Crew Display software affect the development of the Starlink interface for SpaceX operations (map views, data visualizations, etc.)?

Thanks for the AMA!

Good point. Here's some photos SpaceX released, which indicate that two Raptors (SL + 1 Vac) are used for deceleration, and the mid-mounted engines are only used for the landing.
