Some More Details on the Firefly-Aerojet Rocketdyne Partnership

Main Engine Cut Off

I still think that as a launch services company, it’s a bad idea to put yourself in a situation where you’re beholden to someone else’s business for your core engines. But the confirmation of moving to a single-core, reusable first stage, along with a doubling of Beta’s previous payload is at least the best case scenario here.

Firefly Wins MECO’s 2019 Bad Decision of the Year Award

Main Engine Cut Off

I’ve been genuinely excited to see what Firefly can do in the launch market. And I still am excited to see Alpha, but for Beta, this is a major violation of the rocket equivalent of Alan Kay’s theorem: people who are really serious about launch services should make their own engines.

I’m Heading to IAC 2019

Main Engine Cut Off

Big week coming up: I‘ll be heading down to DC for IAC 2019. It’s sure to be packed with announcements and interesting information, so keep your eyes peeled here on the blog, over on Twitter, and become a supporter to get access to any and all bonus content I produce throughout the week. I will likely be doing some ad hoc recording (maybe even interviews?), so it’s a great time to hop in and support!

The RFP was released back in August, and as we heard then, the program contains up to 20 missions that will be competed as they are ready. The selected launch providers are a nice mix of those who are flying today, those who are coming up on their first flight, and those who are still early on in their work.
