We've never seen anything like this recording of a landing on another world. @fireflyspace

Space Force failed to issue a decay notice for VAST's Haven Demo, which was removed from orbit on Feb 5. It's still in the US satellite catalog as 'in orbit'.

@JonTheBeagleDad Most people suspect that donating $1.8 million to election campaign probably helped. apnews.com/article/nikola… The pardon also wiped out the $660million he was supposed to pay back to victims.

@DJSnM so how he get a sweet heart deal ?

After being sent to prison for defrauding investors this guy is back with 'AI Jets'. I think I'll pass. techbuzz.ai/articles/pardo…

@JonTheBeagleDad I'm not talking about the tech, but the person who went to prison until he bought a bunch of 'get out of jail' crypto.

@DJSnM why . you love this kind of tech hahha

@WayCharMar It’s so obvious what they’re meeting in LEO I didn’t think I needed to say it.

@DJSnM There’s a much easier option but no one wants to say it!

With Orion being set for a Centaur V upper stage NASA could start launching it into LEO on Vulcan. Then there would be no need for Starliner, for LEO crew redundancy. And if a ferry stage were implemented to take it to the moon then SLS isn’t needed for Artemis. Boeing would not be happy.

Need ultra high vacuum compatible taps to leave broken in all my parts

@JoelSercel @elonmusk @peterrhague Without carbon on the moon you can make Silanes if you want methalox like performance, but they have awful problems with silicon dioxide deposits in engines. While you're chiseling quartz off your turbomachinery you can watch asteroids sailing by.

I love the concept of mass drivers on the Moon (makes a lot of sense), but the first million tons is way easier with these highly accessible small asteroids. By the way, Elon here is a freebie for you: if you put a mass driver near the South Pole at about 35º elevation angle (the crater rim angle as it happens), there is an azimuth that will allow it to deliver payloads to an L2 halo orbit. Also, not enough carbon on the Moon to resupply your methane rockets. There is plenty in the asteroids.

Mass is the key constraint in doing anything at scale in space. We can launch more from Earth, but sooner or later we need to use the materials already out there…

@NolanTrees @25YearsAgoLive I remember this, I also knew it had zero chance of hitting this.

@25YearsAgoLive @DJSnM

Taco Bell announces a promotion to coincide with the re-entry of the Russian Mir space station. The company tows a large target out into the Pacific Ocean and announces that if the target is hit by a piece of the Mir, every person in the United States will get a free taco.

@ToughSf Tidal effects are much stronger in this system because everything is closer together.

The planets of the Trappist-1 system all have similar densities and lie in very circular orbits. They all sit practically in the same flat plane, within 0.1 degrees of inclination of each other. For comparison, our planets have between 0.77 and 7.01 degrees of inclination.

@ezrafeilden Yeah, I intentionally kept things simple,

One glaring missunderstanding in this analysis - sunlight has a very different wavelength than your IR blackbody radiation. This means you can paint your radiators with a material with high IR emissivity and low optical absorptivity (ie white paint), so they reflect/scatter 90% of sunlight but act as good high emissivity radiators. This is why the ISS radiators are white and operate just fine in the sun.

Rather than arguing based on 'feels' or asking AI to make up an answer that sounds plausable, I actually did some math on cooling data centers in space, while explaining the basics of thermal balance. patreon.com/posts/cooling-… Shame I overestimated the size of the spacecraft, but, the numbers are at least in the right ball park.

@kevdog114 @Forty1_0 Worth thinking

@Forty1_0 @DJSnM thoughts?

Our largest launch contract yet: 20x new HASTE launches for @DeptofWar to accelerate hypersonics for America. We're delivering reliable, modern hypersonic capabilities to the nation with speed and affordability - and the first mission in this block of launches is just months away🚀

NASA Administrator Jared Isaacman kicks off a screening of Project Hail Mary at the Air and Space Museum. This is going to be good.

@peterrhague @TiagoNugent One of the problems with the larger CBA is size changes due to thermal expansion.

@TiagoNugent Nah, it’s too small. Need APAS+

in 300 years we will still be using APAS-derived ports to dock our beam-core antimatter engine powered ships to our O'Niell cylinders

@JoelSercel The asteroid redirect mission returns!

The secret plan is out! Two great articles today about our plan to capture a small asteroid and bring it into Earth orbit. The concept is part of our New Moon mission, which explores relocating a small near-Earth asteroid into a controlled orbit as the first step toward building industrial infrastructure in space. Our team has been developing the key technologies for this approach for years, including capture mechanisms to constrain and move small asteroids and orbital debris. Accessing materials already in space could eventually enable a new generation of industries beyond Earth. If you're interested in the future of space resources, these articles are worth a read. hashtag#space hashtag#asteroidmining hashtag#spacetechnology hashtag#spacex hashtag#venture

@JasonDoege @NickKayal It's another metric showing declining viewership of live events.

@DJSnM @NickKayal Is that a counterpoint or are you saying it's the same phenomenon?

Oscar ratings decline in two decades: 1996 - 45 million 2006 - 36 million 2016 - 34 million 2026 - 17 million It’s over for these networks. TV only exists anymore for live sports.

@rmtanca @MCCCANM It is being built by a private contracting firm C.A. Rasmussen, Inc. 101wildlifecrossing.org/crossing-faq/

I wonder if this had been built using a private contracting firm how much it would have cost and how long it would taken to complete? Projects like these are not completed on time because there is no incentive to do so. The extra cost is just born by the tax payers - most of which are Newsom supporters who gladly lap this gruel up.

I think these things are useful in some places, probably not in others. CO just built one, the I-25 Greenland Wildlife Overpass. They did it in less than a year at a cost of $15 million. CA? Already been 4 years, $114 million & still not done. That’s grifting!

Prior to fram2, many people were concerned about polar radiation. However, it was actually the South Atlantic Anomaly that contributed a significant portion of our radiation dose. A spike is visible each time we flew along ~45°W longitude. By flying in a polar orbit, we actually spent less time crossing the SAA than we would have in a 51.6° ISS-like orbit.
