In this episode we recap PT2 of NASA's ambitious plan for the moon with live reactions from Alex during last Monday's epic reveal of the Ignition Plan. This part is dedicated to orbital space stations and NASA's controversial pausing of Gateway (the planned but underdeveloped Lunar Space Station) and their plans to replace the International Space Station in Low Earth Orbit.

2026/03/19

In this episode, Alex catches up on some of the latest projects he's been working on between using Space Internet (Starlink) and the testing on the 3D Printed Starlink mount. The topic of "rethinking failure" has continued to stay in the zeitgiest after the new NASA Artemis plan. As a classically trained Aerospace Engineer, Alex thought it made sense to dive into this idea more. As a maker at heart, failure is thought of as a necessity in development so that you LEARN quickly. For the "classic" way

Jared Isaacman, previously chosen as the President's pick for NASA Administrator in March 2025, faced the Senate committee hearing AGAIN to discuss his qualifications and potential conflicts of interest before leading the American Space Program. The past year of delay was due to political nonsense, leaving NASA without leadership that whole time.

We went live for the NASA broadcast of the release of images of the Interplanetary "comet" 3I-Atlas, which was delayed due to the government shutdown. As the cultural curiosity surrounding 3I-ATLAS went viral during the poorly timed government shutdown, it was a unique opportunity for NASA to do what it does best. Share data and spend a little more time with the actual experts to explore that curiosity and dig deeper into what we found. Unfortunately, it feels as though the government shutdown and
