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

Space is hard

[Dago @dagorenouf]

Some people probably hate Elon because he's rich, but personally I just feel betrayed by him.

I genuinely believed he wanted to help humanity. Until I realized he didn’t.

He said he bought twitter to protect free speech → ended up building a right-wing propaganda machine to win the election.

He said he sent StarLink to help Ukraine during the war → now tries to undermine them by saying Zelensky is a dictator.

It’s always the same pattern:
1. Start doing something inspiring that makes him look like a hero
2. Eventually change direction towards whatever gives him more power
3. Don’t take accountability and leave people in the dust

He’s not a nazi.

He’s just a textbook narcissist who manipulates the truth to gain power.

Now I still manage to separate the narcissist from the genius:
- I like Grok
- I like X
- I like StarLink
- I might buy a Tesla someday

But I’m just disappointed.

Because I believed he was driven to help humanity.

But in reality he’s just driven by power.

[Paul Graham @paulg]

Pétain and the Vichy government have very few open fans, but if it was happening now, they'd have lots of fans on Twitter. Or at least there would be lots of accounts posting in support of them, many of which would be fake.

It is sometimes hard to find the balance between allowing yourself to change and ensuring you don’t disappoint your younger self.

[Boom Supersonic @boomsupersonic]

Boom is supersonic. On Jan. 28, 2025 at 8:31am PST / 16:31 GMT, XB-1 broke the sound barrier.

Chief Test Pilot Tristan “Geppetto” Brandenburg safely and successfully achieved supersonic speed in XB-1, the first civil supersonic jet made in America.

✅New top speed: Mach 1.122 (652 KTAS)
✅New max altitude: 35,290 ft.
✅Flight time: 34 minutes
✅Airspace: Bell X-1 Supersonic Corridor and the Black Mountain Supersonic Corridor in Mojave, CA

XB-1 demonstrates that Boom has the team, technology, and tools to deliver supersonic commercial travel with Overture, cutting travel times in half.

Congratulations to the Boom team on making aviation history!

Hello World, please say hi to MirrorAI 🪞

An AI friend I built for myself and decided to share with the wider world this morning.

Essentially, it is ChatGPT with a bunch of extra capabilities.

The process to bring MirrorAI to life was as follows: asking myself “Why can’t I do that with ChatGPT yet?” → Implement → Repeat

Here is a short demo video of some of its capabilities.

If you want to join the waitlist, just click here: https://t.co/axXiV966cJ

[Blue Origin @blueorigin]

New Glenn safely reached its intended orbit during today's NG-1 mission, accomplishing our primary objective. The second stage is in its final orbit following two successful burns of the BE-3U engines. The Blue Ring Pathfinder is receiving data and performing well.

We lost the booster during descent. We knew landing the first stage on the first try was ambitious. We'll learn, refine, and apply that knowledge to our next launch in the spring. We're thrilled with today's outcome. More: https://t.co/5cF4ACgm3X

congrats @blueorigin!! 2025 promises to be a major year for space.
