“Elon Musk has actually figured this out. They don't really talk about it as a strategy, but if you look at his portfolio of companies, that is the strategy: figure out how to get some sovereign capital, get to scale, and then cross over into lower-cost consumer goods."

US Says Antares' Small Nuclear Reactor Reaches 'Criticality'
“The Trump administration announced a small modular nuclear reactor reached a critical milestone Thursday.
The small reactor being developed by Antares Nuclear Inc. participating in an Energy Department pilot program reached "criticality," the agency said in a statement. The milestone occurs when a nuclear chain reaction becomes self-sustaining enough to produce a steady release of energy.
The Energy Department has set a goal of achieving the milestone in at least three test reactors by July 4 and selected projects from Antares, Oklo Inc., Aalo Atomics Inc., Atomic Alchemy Inc., Deep Fission Inc., Last Energy Inc., Natura Resources LLC, Radiant Energy Inc., Terrestrial Energy Inc., and Valar Atomics Inc. to participate in a program designed to expedite development and authorization of reactors.
Antares is the first of the cohort to reach the criticality milestone." (via Bloomberg)

"Muon Space announced a Starship-class satellite platform June 3 designed from the ground up to meet the demands of the emerging orbital data center market, with an initial launch slated for 2028 after securing customers.
The Condor-Ultra platform would initially offer 20 kilowatts of baseline power and more than 18 square meters of nadir payload area, with Starlink Mini Lasers from SpaceX to use its broadband constellation for inter-satellite data relay.
Condor-Ultra is designed to scale depending on mission requirements to 100 kilowatts of power, with "native Starship stackability" for deployments of hundreds to thousands of satellites at some point after the rocket enters service.” (via SpaceNews)
