Helium's lifting capability is proportional to the density of the atmosphere, which is very low on Mars.
Hydrogen it is.
Hydrogen leaks.

These are self-reported stories by one of the most extreme self-promoters in business. Let's not take it too seriously.
I wouldn’t take them seriously, except that SpaceX has a full decade of very reliable launch services at a fraction of the cost. You might ask how they did that, and SpaceX says “here are some examples”. It’s not just reusing rockets.

Right, but why would you believe what they say? I believe they know how to launch rockets, but that doesn't mean they are telling you the reason. They may not want it public, they may want to kiss someone's a-.

If there’s any company you should pay attention to when they report successful cost cutting, it's spacex. You can hate or love Musk but Gwynne Shotwell is the real deal there. Not sure how she keeps Elon from blowing the whole business up but somehow she does and quite successfully at that. If she says you can keep cool whatever needs cooling for 10% of the Boeing price, you’d better believe it.
I'd better? Or else what?
That's not persuasive. People make things up all the time, especially stories that show how smart is.

#146> "Good news today," NASA's Jet Propulsion Laboratory (JPL) wrote on X, formerly Twitter, late Saturday.
I heard this line in my mind with Professor Fansworth's voice.

Fun fact - the cameras that captures Perseverance's landing are also Linux based and vim is installed - at least on the later model that I worked with.
Using it with a 20 minute delay between keystrokes and their results must be interesting
Huge delays between keypresses is what vi (and vim ofc) was designed for.

I don’t think you’re supposed to hold your breathe when lifting…
Jokes aside, you absolutely are. Bracing properly is a critical skill in both olympic weightlifting and traditional strength training.
Ah, shows how much I know about lifting... in general I've always been reminded to keep breathing when exercising.

Or else? I won’t ground you for a week for sure ;) Being wrong for the wrong reasons is good enough. You have proof their methods work in their launch manifest.

This isn't about their methods. You think Musk is honest because their launches are successful?
