SpaceX Parachute Test
Crew Dragon parachutes successfully deploy during latest development test that simulated a pad abort, where the vehicle is tumbling at low altitude before parachute deploy, validating SpaceX’s parachute models and margins.

THE GLOBAL CLIMATE STRIKE IS HAPPENING NOW
This week will be historic. In over 150 countries, people are stepping up to support young climate strikers and demand an end to the age of fossil fuels. The climate crisis won’t wait, so neither will we.
Young people have woken up much of the world with their powerful Fridays For Future school strikes for the climate. Now, millions of adults are joining in a huge wave of that will kickstart renewed action all over the world. The urgency of the climate crisis requires a new approach and a just response centered on human rights, equity, and justice. Follow the actions and join the movement.

Everyday Astronaut explaining how flaps control flight (twitter video), followed by informative Elon tweets
Everyday Astronaut explaining how flaps control flight (twitter video)
Elon: That’s correct. Essentially controlled falling, like a skydiver.Viv: ... but what's used to actuate the fins? Some kind of small motor?
Elon: Many powerful electric motors & batteries. Force required is enormous, as entire fin moves. More about this on the 28th.Elon: It does actually generate lift in hypersonic regime, which is important to limit peak heating
EA: Pop back out of the dense atmosphere to radiate heat away and then drop back in 🤔 awesome! ...
Elon: Better just to ride your max temp all the way down & let T^4 be your friend. Lower atmosphere cools you down real fast, so not crazy hot after landing.Oran Maliphant : Is “sweating” methane still an option?
Elon: Could do it, but we developed low cost reusable tiles that are much lighter than transpiration cooling & quite robust
\ok, I was steadfast that Elon's statements said nothing about future use of transpirational cooling, I will concede that this is not a defensible position anymore, ha ha])Scott Manley: And just like that I need to rebuild some of my descent models. So the AoA won't be 90 degrees, it'll provide lift to keep vehicle out of denser atmosphere until it loses enough speed.
Elon: Exactly. For reusable heatshield, minimize peak heating. For ablative/expendable, minimize total heat. Therefore reusable like Starship wants lift during high Mach reentry for lower peak, but higher total heat.ShadowZone: So this increases the probability of Starship having to do multiple aerobrake passes when going to Mars or returning, correct?
Elon: For sure more than one pass coming back to Earth. To Mars could maybe work single pass, but two passes probably wise.[Or discuss on r/SpaceXLounge post or Starship thread]

Here’s how #starship controls pitch, roll and yaw (in that order in this clip) using just 4 total flaps. This is a unique form of control. I don’t know of any vehicle that does this with its control surfaces perpendicular to the airstream. Cool stuff @elonmusk.…
