Elon "expects" the rockets to explode. “This is a test program. We expect it to explode. It’s weird if it doesn’t explode, frankly. If you want to get payload to orbit, you have to run things close to the edge.”

I see an “alien worlds”. I don’t see alien planets. But the search function on netflix is pure trash so I may never see it
I am not sure if posted already, but the Washington Post ran an article today. When Trump signed the fiscal year budget in 2020, its 5500 pages included a provision requiring the US Director of Intelligence and Secretary of Defense to make public disclosures about known or suspected UFO activity. Apparently, former US Intelligence Director John Ratliff was on Fox stating there is a lot to disclose.
Some people sit here and don’t think about how we haven’t been annihilated by a supernova like any second
Holy fucking shit this seems like big news: https://www.cnn.com/2021/04/22/world/mars-rover-oxygen-moxie-scn/index.html
wow, that does seem pretty huge. if that tiny thing can produce that relatively quickly, a full scale operation should be able to do a ton. That's pretty amazing.
awesome launch the other morning. SpaceX is really doing it right, they have the "Launch America" thing down really well, doing live desks from the launch pad and their usual excellent launch-casts. Very geeked for all the projects they have going on, especially now with the lunar lander contract.
So I’m sure I’m just dumb on this subject but if Mars has an atmosphere many times less dense than earth’s, how is the helicopter able to get enough air cushion under it to fly? Like is there something different in the design or do I just not understand how a helicopter flys
I don't think choppers need an air cushion the same way a hovercraft does, it just needs something to push off against at a high enough RPM. It's a wee bity helicopter and even though there's a lot less air (equivalent to about 113k ft on earth - helicopter flight record is around 40k) there's also a lot less gravity. Edit to add: I saw one article saying that the real limit to helicopter altitude isnt the air pressure to generate lift on the blades, but air pressure to intake air into the jet that powers the blades. Jet aircraft get around that because the forward momentum increases the pressure into the intake. Since the Mars-o-copter is battery powered, that isn't an issue.
the problem with doing anything with Venus is it's like dropping an ice cube in a pot of boiling water. As soon as your rover or whatever lands, the planet just ruins it. If they've figured out how to get long-term, reliable expeditions there, that'd be awesome.
I'd be interested to know how they're gonna do topographical analysis through that cloud covered hellstorm.
Synthetic aperture radar imaging is pretty weather-proof. You just have to pick a band width that's not in an atmospheric absorption zone.
Headed to the beach to watch Falcon9 launch up close today, fingers crossed for good weather and launch on schedule
Shouldn't take Venus to be able to accept the simple fact that climates change, but hey here we are in this great amazing society with totally smart and science based awesome people.
