- Everyday Astronaut asks great question: Why is NASA spending $700 million for developing new SLS upper stage when ULA’s Centaur-V is available for only $120 million?
Tim Dodd seems baffled, but then he is young and hasn’t lived through decades of NASA pork that accomplishes nothing. That new upper stage is just more of the same.
- NASA astronaut shows off Orion’s bathroom
Talk about overkill for a capsule. No wonder Orion is too heavy for almost every rocket available.
- Startup Apex to fly a commercially-developed space-based interceptor demo on its own dime
The company hopes the mission will convince defense contractors and satellite companies to buy its product.
- A rehash of Sierra Space’s Dream Chaser project
No real news, though overall the article underlines the failure of Sierra Space to get off the ground. It also provides evidence to explain why NASA abandoned Dream Chaser as an ISS cargo craft.
- Blue Origin touts the delivery of its 30th BE-4 engine to ULA
This gives ULA enough engines for at least fifteen launches of its Vulcan rocket, which is about the number of launches the company hopes to do in 2026
- In 2010 NASA analyzed what museums to send shuttles to and ranked Houston low
So what? These bureaucratic rankings meant nothing. All that mattered for choosing the cities that would get shuttles were political considerations, and Obama wished to reward blue states.
- Video of the demolition of one of the service towers for the Zenit rocket at Baikonur
Zenit was built by the Ukraine, now banned by Russia from Baikonur. Russia now wants to use this launchpad for its new Soyuz-5 rocket. Kazakhstan, which owns the site, has been resistant. It is unclear if this demolition means Kazakhstan has changed its mind.
