Main Engine Cut Off

Architectures like these could flourish with the budget levels that SLS and Orion receive. Things are coming to a head now with the NASA exploration program, and it’s hard to say where it will go. No matter what, the next few years are going to be thrilling.

Thanks to my patrons for the month of February. If you’re getting some value out of what I do here and want to send a little value back to help support Main Engine Cut Off, head over to Patreon and donate as little as $1 a month—every little bit helps.

Interestingly, he didn’t rule out a near-free return trajectory, which is seeming more likely for the currently-planned EM-2. As I said in the latest episode of the podcast, “Then what?” is the most important question this study has to answer. Putting crew on EM-1 and leaving the entire roadmap after that unchanged doesn’t accomplish anything more than a stunt.

I don’t envy the people making the call on which launch vehicle to go forward with, or making the call on when that decision is appropriate. From where I sit, it’s too early to narrow the options down to only SLS.

Last year, Masten’s Phase I SBIR proposal was selected which helped support the initial development of the engine. In that abstract, they discuss usage of this engine and its derivatives as propulsion for a Mars ascent vehicle, and Xephyr, their entry into DARPA’s XS-1 program.

Good to see more activity on this front.

The company says it plans its first launch of a Ukrainian-Russian Zenit-M rocket — similar to the ones used by Sea Launch — from the Baikonur Cosmodrome in Kazakhstan by year’s end. The launch is meant to work out kinks in operations before rebooting the Sea Launch platform.

“Just.”

I’m not sure whether this will be interesting, entertaining, or something else, but it’s got potential.

A perfect Florida sky, the blending of past and future hardware with the weathered Fixed Service Structure and SpaceX’s brand-new transporter-erector, the sleek-as-ever Falcon 9 complete with landing legs…the absolute beauty of this photo is endless.
