That's what the 'Quiet' part of the name is trying to solve. From another source: The X-59 has been designed to achieve a PLdB of 75, similar to what might be heard when standing n…

Not mentioned in the article is that NASA has also been experimenting with the viability of using Nvidia GPUs for space-based applications: https://www.google.com/url?sa=t&rct=j&q=…

Not anymore. Especially not if you google "RHEL laser".

That is definitely not how China would enforce it. You need a Starlink terminal in order to communicate with the satellite. China will most likely just block the sales of Starlink …

Your statistic in no way diminishes the losses that each country suffered during the war.

I find it hard to believe that they are completely re-designing the avionics/flight computers because of this gamma ray incident. There must be another reason. If it's seriously th…

There's also currently a push by many countries to have carbon monitoring satellites above their countries. For example: https://www.scientificamerican.com/article/meet-the-satelli…

Do you use the internet? GPS? Where do you think those technologies come from?

It’s likely that your work and life has greatly benefited from technologies that originated from the military.

I think we have been desensitized by all these SpaceX rocket landings. Propulsive landing is not as easy as it seems.

Imagine you are SpaceX. You are going to be launching a Starship. Given how booked your launch manifest is, would you rather launch a cubesat or a full-sized payload? Which would e…

1. It's not always feasible to launch your spacecraft with Starship (e.g. it wouldn't make sense if you are just launching a cubesat). 2. That's a pretty aggressive timeline to hav…

Oh yea? https://www.newscientist.com/article/2215303-spacex-satellit...

Starship still needs to fire rockets in order to land. I would say it's a crazier idea than the ones you have mentioned. The previous solutions you have listed were used precisely …

You can be sneaky sure, but that what background checks are for - to see if you are a trustworthy individual.

I mean, the whole statement is not correct. Sure JPL manufactured some things but it also acts just like NASA, managing the Mars projects. Most of the spacecraft I would say were m…

An electronic watch is ok. Just not with cellular, wireless or bluetooth, USB capabilities.

Every manufacturer needs a good revenue source. Unless you are a manufacturer that is making mass market cars like Honda and Toyota, you need to create cars that people will buy if…

So is your idea to have spacecraft go to LEO first instead of direct GTO? Is this an efficient use of fuel?

Who is "we"? Care to identify yourself? What existing interface are you talking about? Which GEO manufacturer is making 5000 lb spacecraft?

I didn't research every spacecraft but if you look at GTOSat, its intended orbit is GTO, so it won't really need the services of Epic since a rocket can place them there directly. …

Is this even true? https://gomspace.com/shop/subsystems/attitude-orbit-control-... https://www.cubesatshop.com/product/ifm-nano-thruster/ https://www.vacco.com/space/chems-overview…

I totally agree. You still need to get the fuel to space regardless of who is doing the propulsion work. Let's say that your tug is already on-orbit, how is the fuel going to be br…

They also mentioned that they can afford to have satellites fail since they are cheaper and sending up so many. Also won't be possible with one-off GEO birds.

I think this is only true for small LEO spacecrafts that are more or less 'disposable'. For higher cost GEO and interplanetary spacecraft, consumer electronics are not going to be …
