In 1972, the final lunar mission of the Apollo program took place, finally sending a geologist to study the moon up close.

In the early morning of November 16, the SLS launched for the very first time.

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.
