THE STARSHIP PROGRAM EXCITEMENT GUARANTEED

At risk of stating the obvious, "rapidly reusable" tiles probably shouldn't do this

Annnnd China dropped another booster stage full of hypergolics on a local village

SHE'S BEAUTIFUL

For anyone currently distrustful of Boeing may I introduce you to their new hypersonic missile revolver

ARTEMIS II LAUNCH AS SEEN FROM THE TOWER RAHHHHHHHHHH

You can thanks NASA supercomputers and wind tunnel testing for that sick background

This video of the Starship touchdown is INCREDIBLE -BUT- Ship 11 did not hold up as well as I initially thought. This thing was literally cooked. Nose on fire. Tiles missing everywhere. Lots of damage near flaps and burnthrough on tank. How reusable would this be?

Those pressure waves are nuts

The F-22 Raptor is so freakin cool Airplanes should not be able to move like this

Seriously though find me a city that does New Years like San Antonio ❤️

LAUNCH ABORT SYSTEM JETTISON 😍

It's hard to be an engineer because you are perpetually designing for this use case

You’ve likely heard of V/STOL (vertical and/or short take-off and landing) but what about BTOL (backwards take-off and landing)? The F-35 is truly an incredible flying machine and this shows how the US continues to innovate!! Let’s see the Su-57 do that!

I’m intrigued by the Beta Alia-250 electric vertical take-off and landing (eVTOL) concept: ✅Fully electric, 450+ km range ✅Cruise at 270 km/hr ✅50 min recharge time ✅1/10 noise level of helicopter ✅6 passengers ✅Already multiple test flights Will this tech “take off”?

Some colorful fluid dynamics to brighten your timeline: Here's a sim from Converge CFD of the supercritical combustion of hydrogen fuel &amp; LOX in a DLR subscale rocket engine

Incredible look at the Crow Instability behind an F-15! You see the wingtip vortices interact with the wake/contrails from the engine and turn into those ring-shaped (toroidal) features Beautiful fluid dynamics! HT Bryson Sullivan 🇺🇲 &amp; Jonty

Apparently not yet obsolete...

Watch Anya Live

ARTEMIS II AS SEEN BY THE OFFICIAL NASA CESSNA THIS IS THE BEST LAUNCH VIDEO AND IT ISN'T CLOSE

I love this perspective as well Really showcases how we are "catching" the moon with this trajectory

Mark Fingar captured an F-22 Raptor activating its cloaking device 🤯

This video of Orion slamming into Earth's atmosphere at 11 km/s during the Artemis I mission is absolutely filthy

SO LONG SUPER HEAVY GO JOIN YOUR BROTHERS IN VALHALLA

Gotta hand it to Isar this is the most picturesque launch failure video I've ever seen Space is hard

Have we ever had a first person view of an EVA like this? Wow we're living in the future

SPACEX + NASA TEAMING UP TO YEET A DRONE THE SIZE OF A CAR TO TITAN LFG!!! 😤

Good visualization for the “why are jet engines harder than rockets?” crowd. Those little blades deal with scorching temps and high pressure—consider too the J-79 here is an old one There’s a reason more countries can make nukes than jet engines

🚨EVIDENCE MOUNTING THAT OREO THERMAL PROTECTION SYSTEM IS A GOOD IDEA🚨 Elon Musk OREO Cookie make it happen

This is really something. Shenzhou 18 capsule reentry in front (on the left) and propulsion module burning up in the atmosphere behind

I love this but unfortunately in the realm of things that fly really fast the name SPRINT is already taken...

Still cannot believe we got to watch this in realtime Absolutely wild Have a freakin day Starship and SpaceX

More cool rocket launch drone shots, this time from China Look at that flame trench!

People walking around in moon suits will always look goofy but this is still a pretty fun entrance (and good flexibility) China is going to the moon and just lapped the US in development of a new suit NASA + SpaceX + Blue + Boeing + LM etc need to hustle

SUPER BOWL FLYOVER AMERICAN AIR SUPERIORITY REMAINS UNMATCHED

Chat I think we may have actually dodged a bullet with this one

May the 4th Be With You! Happy Star Wars Day friends Here’s a Millenium Falcon in a Mach 3 wind tunnel (Penn St)😎

MOAR CAMERAS IN SPACE MOOAAARRRRR

So do we just need to try this type of landing on the moon?
