ULA roof snipers?

Sun rising at midnight... I've always thought that was an exaggeration until this pic

To be fair the source is known lying scumbag Peter Thiel so do take with a mountain of salt.

Trump threatens SpaceX contracts with the US government.

Some 2,000 senior level NASA staff are set to leave after pressure from the Trump administration to streamline and privatize space operations and missions. Critics are worried about the loss of institutional knowledge that only a national-level agency can maintain.


On the commercial side, this is SpaceX Falcon 9's first delivery of their rival Amazon Kuiper's LEO broadband constellation satellites to orbit and the third batch of said satellites launched (27+27+24 = 108 so far)


The startup Portal Space has come out of stealth recently after being awarded a contract by DoD last year to develop a highly maneuverable spacecraft. The company claims their Solar Thermal Propulsion spacecraft can generate an incredible delta-v of up to 6km/s to deliver satellites from LEO to GEO in hours and LEO to cislunar in a few days.

Interesting. At first I thought it was a solar sail, but it seems to be some sort of mirror system that concentrates solar energy onto receiver that generates energy similar nuclear thermal propulsion (at least that it what they claim).
