Episode 26 - Hungover on Reentry


Jake and Anthony are joined by Chris Carberry of Explore Mars to discuss his new book Alcohol in Space, and pitch themselves as the perfect test subjects.

Episode T+142: T.S. Kelso, CelesTrak and AGI

Main Engine Cut Off

Last week, I took a ride out to the AGI offices and sat down with Josh Poley and T.S. Kelso. We shot a handful of videos for AGI’s YouTube channel, the longest of which was this interview right here. I talked with T.S. Kelso about the history of CelesTrak.com and satellite tracking on the internet as a whole, as well as a few topics relevant to the modern day: satellite tracking and orbit reporting among operators, conjunction and collision monitoring, and space debris mitigation and management. Be sure to follow along with AGI’s channel as the rest of the videos go live throughout the week!

Episode 25 - SpaceX Cinematic Universe


Jake and Anthony are joined by Marina Koren of The Atlantic to discuss the very Off-Nominal-esque Apollo 12 mission, regional Pennsylvania sayings, and to deliberate on and announce the 2019 Off-Nominal Award winner!

Episode T+140: Launch Protests and Lander Hopefuls

Main Engine Cut Off

Blue Origin successfully protested the US Air Force’s RFP for the National Security Space Launch program, which will have big implications for the way the current round of contract awards plays out. NASA added five new providers to the Commercial Lunar Payload Services program, including SpaceX and Blue Origin, and I’ve got some thoughts about the inclusion of those options in what is quickly becoming my favorite NASA program.

Episode 24 - Jim-Adjacent


Jake and Anthony tell the tale of IAC 2019—meetups, making connections at the conference, trolling around the expo hall, and the much-anticipated-and-surprising meeting with JB.
