One of my favorite missions, EVER! We learned so much. The only way to make sure we didn’t hit one of the moons and ruin any future science, we flew her INTO Saturn.

I’m new to “Astro Kirsten”. *Subscribed*

Anyway, this is an old story told in a new video, but the story is worth retelling.

In 1995, a scientist gambled ten days of the world’s most in-demand telescope on a patch of sky that looked completely empty. What came back changed astronomy forever.

This is the story of the Hubble Deep Field — one of the most important images ever taken, and the astronomers who bet everything to get it. We cover the Director’s Discretionary Time gamble, the colleague who tried to talk him out of it, and how that single image led to the Hubble Ultra Deep Field, the Extreme Deep Field, and eventually Webb’s First Deep Field — each one staring longer and deeper into the universe’s past.

First, I want to say, “Well done”. I hear some serious whining about how China only steals tech from America, blah blah blah….

Are the same people acknowledging the fact that Blue Origin is more of a copy than this latest accomplishment? Elon is all about moving humanity forward, and reusability is a big part of his vision. He has said publicly that he is impressed by their progress. I say “well done” to any launch provider that can re-use a booster, and even more so, a second stage.

I’ll let them speak to the details, and trust me…it’s fucking awesome.

The International Space Station is 25 years old, cost $155 billion, and leaks. A startup called Vast thinks it can build the replacement for about a billion dollars, and it plans to launch the first piece in 2027. In this episode, Ashlee Vance heads to Vast’s headquarters in Long Beach, California for a full tour of Haven-1, the spacecraft the company expects to be the world’s first commercial space station. Vast is the wildcard in the race to replace the ISS, moving faster than rivals like Axiom, Blue Origin and Starlab, and it’s doing it the SpaceX way: everything designed, built and tested in house, from the hatch to the micrometeorite shielding to the actual flight hull sitting next to the cafeteria.

The money comes from Jed McCaleb, the crypto billionaire who believes humanity needs a frontier and is willing to spend a fortune to open one. The building falls to CEO Max Haot, who walks Ashlee through mission control, the hull welding operation, and the numbers that make competitors nervous. Vast builds pressure vessels in six months for under $5 million while others pay 55 million euros and wait four years. NASA showed up in 2023 expecting a science fair. They’ve been coming back every quarter since.

Then NASA astronaut Drew Feustel, who spent 225 days on the ISS, takes over for the fun part: a space food taste test featuring freeze dried tiramisu and tales of trading for duck confit in orbit, the largest window ever flown to space, a zero gravity sleep pod that hugs you, and a walkthrough of Haven-1’s surprisingly roomy interior. Four people will live aboard for two week missions, with a SpaceX Dragon serving as taxi, lifeboat and bathroom. Ashlee walked in skeptical after 15 years of covering commercial space delays. He walked out believing this thing is actually going to fly.

This is how we first *saw* the massive black hole at the center of our galaxy.

This is too damn cool not to share.

That is a big list, seriously. I just love ASTRO_ALEXANDRA though the name could use some work, haha.

Holee-fukka-molee…BOOOOOOM!!!!! To be fair, SpaceX has had their share of boom during development.

Fantastic video!!! Let’s GOOOOO!!!!

From Astrobotic on YT.

Astrobotic today announced the successful hot fire test of its Chakram rotating detonation rocket engine (RDRE) at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

Two Chakram engine prototypes completed eight successful hot-fire tests, accumulating more than 470 seconds of total run time without any discernible damage to the engine hardware. The campaign included a 300-second continuous burn, which is now believed to have set the record for longest duration hot firing of an RDRE engine to date.

During testing, each engine produced more than 4,000 pounds of thrust, making Chakram one of the most powerful RDREs ever demonstrated.
