John Gowan interviewing our very own @natosaichek on the largest technical challenges we face transiting the lower atmosphere at orbital speeds.
Space-gun space-fun!

Cool to see my art up on the wall. Thanks @_mikegrace
My pal Adrian paints as a hobby. He made two lovely abstracts of a locomotive and a spaceship and offered them gifts.
He gave me the go-ahead to make an AI space gun in his style. I just ordered it as a poster that'll hang in the foyer with his other two.

There is nothing more important than defending Western Civilization
So I am happy to say I'm bringing the USS Hornet Defense Tech Hackathon back as an annual tradition.
360 hackers on a WW2 aircraft carrier. Overnight in the bunks.

coolest gift ever. space trading cards from @StarbenchA
thanks so much @kmcannon!
Great article.
Can Longshot Beat Starship on Launch Costs? starbench.substack.com/p/can…
There are two audiences / PMF’s for space guns: defense needs affordable hypersonic tests, and launch demand is climbing.
Longshot built the world's largest light-gas gun near SF to serve both.
Hypersonics now, orbit at $100/kg next.

Longshot is trying to build a gun big enough to make space data centers a reality.

excited to pitch at TC Disrupt this morning!
Longshot is in the Top 20 at @TechCrunch Disrupt!

In 1992, John Hunter’s SHARP light-gas gun at Lawrence Livermore fired 5 kg projectiles at 3 km/s using compressed hydrogen.
The gun worked, but the follow-on satellite launcher needed ~$1B, and in the post-Cold War ’90s, nobody was buying. Funding ended in 1995.
In 1966, Gerald Bull’s Project HARP fired a Martlet 2 projectile to an altitude of 180 km from a 16-inch gun, setting a gun-launch record that still stands. Each shot cost about $3,000.
The gun worked, but the satellite market it needed didn’t exist yet. Caught in the crossfire of political opposition and shifting government priorities, the project lost its funding in 1967.

@_mikegrace on why deep tech founders should stop reaching for new technology:
"I'm an economist. I see the world change through incentives and markets."
"There is nothing about the Falcon nine, the reusable rocket that they built, that could not have been built in the 1970s."
"You get a hard problem or you get technical novelty. You can't do both. You won't succeed."

@_mikegrace started @LongshotSpace at 35, broke, after asking his wife for six months of no income:
"I was borrowing money from the bank of my wife. So just living off of my wife, super uncool."
"I was paying myself $1,000 a month, and the rest of it was going into plastic for supergun."
"Everybody at Longshot knows everybody's salary... Everybody knows my salary. Everybody knows how much of the company I own."
"I can't pay you like Google... But I can be open with you. And that in itself is a kind of compensation." – at San Francisco, CA
"If you have a very small probability of owning the solar system, it's worth it."
@_mikegrace is building giant Space Guns that throw things to space, no rocket.
In this episode of ODDS, we went inside @LongshotSpace for a test fire and hear how Mike went from backyard potato guns to Air Force funding, nearly going bankrupt three times along the way.
0:00 Throwing things into space
3:49 The "everyone else is wrong" mindset
5:36 Why we really use rockets
10:36 Why you should build a bad prototype first
11:33 The first 60 pitches
12:46 Almost bankrupt, three times
14:22 Why everyone knows everyone's salary
21:13 The test fire
23:55 Think like an economist, not an engineer
25:36 Launching a Tesla, and what success means
