Re: SpaceX News

A new Ars Technica article backs the idea that Musk is excited about the Starship design changes: But above all these things, Musk is a geek at heart, in the sense that geek means a "knowledgeable and obsessive enthusiast." He is knowledgeable about rockets and obsessed with their details. In shari...

Re: SpaceX News

I dunno— Musk seemed pretty excited about this when he first tweeted about the “delightfully counterintuitive” design change they had in store. Musk seems pretty transparent in expressing his feelings; I’m betting this came from SpaceX, not a NASA compromise.

Re: SpaceX News

Yes steel. AFAIK, the reason he’s tweeted about isre-entry heating, not radiation— but the radiation seems like a fair point too. Steel holds strength in high temps unlike carbon fiber. Rather than use an ablative heat shield, active cooling using fuel as the heat sink. Also, he claims to have a new...

Re: SpaceX News

Spoke a little too soon skipjack... EDIT: Made original comment as the booster was spiraling out of control and was picturing a fireball on impact (was hoping not in a bad place). Pretty phenomenal that it apparently actually kept enough control to make a controlled water landing-- can't wait to see...

Re: SpaceX News

Per tweet today from Musk, there are new radical changes to BFR; BFR is being accelerated in place of Falcon 9 stage 2 reusability.

Guesses anybody? (Hint: Musk says the changes are “counter intuitive”)

Re: SpaceX News

They didn’t even try to catch. No reason was given, but rough seas + night attempt may have been factors.

Awesome time lapse:

Re: More Helion Energy news....

Nevertheless, the 2018 date is good news (assuming NBF info is not 2 years old). It seems this Seattle Business Magazine story from April is the source for this NBF article; looks like they took a bit of info from that article (including the end-of-year target) and mashed it with existing copy on H...

Also 1500 installations and 6 years of field testing? Could be legit?

Re: 2018 NIAC Symposium

I’m a software developer, not a scientist, but I think there’s a strong parallel with the “it works on my machine” phenomenon I’ve experience quite often. Frequently code written on my machine that works great for me ends up not working for a tester (or worse, a customer) because I didn’t account fo...

Re: 2018 NIAC Symposium

Heidi Fearn will be taking a working device to Dresden and will stay with them until they get it working. Dresden had problems with a previous device and published bad results.
Hmmm. Does this interfere with the concept of independent validation?
