Starship plasma colours explained?

Evidently, those brilliant Starship plasma colours were caused by compression, not friction?!

Using HLS Starship for a Mars flyby?

While Starship has not yet been crew rated for launching people from Earth to Orbit, it is clearly going to be rated for lunar landing eventually. This present an opportunity. With the large ∆v budget available, you could launch one on a flyby trajectory past Mars. If you launched a Dragon on a Falcon 9 to go dock with a fully fueled HLS in LEO you could kick the whole stack onto a fly by trajectory out to Mars. The Inspiration Mars mission provides a general concept, but using HLS rather than SLS provides a much greater amount of consumables and ∆v capability. This would likely allow for a crew of four or even six astronauts. The reentry at the end of the mission would be done using the Dragon capsule, plausibly with some retropropulsion to reduce the reentry velocity.

This could likely be done a lot earlier than a manned mission using a regular Starship vessel, and it would provide us with a much lower response time for the remote operation of rovers and robots.

What is going on with the Deep Space Transport? What's the plan? Who's making it? Are NASA going to ditch the idea in favour of Starship?

Average Crew makeup on the ISS?

i am planning to write a short internet story about a fictional version of the ISS amd its crew, but don't know what the makeup would be like. Like how many be of what nation's space agency, what types of engineers or scientists be on board, who is necessary to keep things going, ect.

When hypergolic thrusters go wrong...

What would happen to a hypergolic thruster if one of the oxidizer or fuel supplies fails to actually supply any juice? I am thinking about helium-pressurized tanks and a valve to allow flow to the combustion chamber, like Apollo LM or Soyuz steering thrusters. I assume that the helium pressure is designed to be higher than the combustion chamber pressure, to push more juice in there, but if only one of the fuel or oxidizer is supplying, there wont be an ignition, and the thrust chamber pressure will be low. Does this result in a huge rush of fuel or oxidizer out into space? Is it common to have a thrust chamber pressure or a flow rate monitor to shut things down if this occurs?

Is the performance of nitrous oxide good enough to make a feasible orbital rocket?

The benefits of nitrous oxide make it a pretty interesting thing to consider, things like it’s temperature just being relatively cold instead of cryogenic, to being self pressurising, the nitrogen having a lower molecular mass, and maybe being less corrosive because of the nearly inert nitrogen, it not being dangerous like all other room temperature oxidisers, etc… maybe in the future with reusable rockets and commonplace launches, factors like that which value simplicity, reliability, and safety will be more favorable over a super high performing oxidiser like lox. But the main question is, is the performance of nitrous just too bad to go orbital with, even with just a first stage?

Looking for an Animator for Spaceflight Videos

I make videos for my YouTube channel, “Just Rocket Science”. My explanations are getting more complex and I’d like to work with an animator. I wanted to post in this sub, just to see if there are animators specifically interested and passionate about the New Space industry. DM me if you are looking to work on something like this.
