Liftoff: Recent Episodes
Relay FM
Liftoff is a podcast about space, the universe, and everything. You don’t need to be a rocket scientist to understand the major developments as explained by enthusiastic space fans Stephen Hackett and Jason Snell. Hosted by Jason Snell and Stephen Hackett.
Jason and Stephen pop open the hatch to marvel at the JWST's first images, talk about the SLS and wonder what is going on with Russia and the ISS.
In April 1972, the crew of Apollo 16 spent 71 hours on the surface of the moon after a series of technical glitches put their landing in jeopardy. The second of three J-missions, the crew spent nearly three whole days on the surface and completed an EVA on the way home, returning one day earlier than initially planned.
The SLS has enjoyed some Florida sunshine but is headed back to the VAB for more work. This time, Stephen and Jason catch up on NASA's new rocket, plus some other news.
On this special episode, Stephen and Jason celebrate the launch of the James Webb Space Telescope and talk about the future of the podcast. The short version is that we will no longer be publishing every other week. Moving forward, we'll be recording special episodes as major news warrants.
Days away from (hopefully) the launch of the James Webb Space Telescope, Stephen and Jason talk about the hype around the mission, as well as the latest with SLS and Starliner.
The future of the International Space Station is the topic of a new report, all while the SLS inches closer to its first launch. Also: DART is on its way to a celestial crash and a spacewalk has been delayed thanks to debris from the recent Russian ASAT test.
