Ad Astra editor in chief Rod Pyle joins Leo to talk about today's SpaceX Transporter launch, where they set a new record by launching 143 satellites on a single launch. Most were small, microsatellites, others were standard satellite size. Interestingly, the satellites were in various trajectories, causing the launch vehicle to do a corkscrew trajectory to orbit to deploy. On top of that, Space X was able to land the booster for the fifth time in order to recycle it for a future launch. It was the 73rd recovery of the booster stage.
Rod Pyle joins Leo to talk about how the computer used on the Saturn V moon rocket is back in the news. Back in the 60s, computers were housed in rooms. During Apollo, they had to shrink computers down to the size of a briefcase. The computer was housed in a ring section between the stages, and it controlled the firing sequence and the flight up into orbit. It also had its own cooling system. What's amazing is that they survived even a direct lightning strike on Apollo 12. So it was very robust.
Rod joins Leo to talk about the latest news in space exploration. And there's more alien news, as more alien radio signals keep getting picked up by radio telescopes. But the thinking is that most technological civilizations have probably destroyed themselves. But there could be species that are just as young as we are that could be out there, and that's where the signals are coming from. The problem though, is that they are probably not as technologically advanced to get here. In the end, we're pretty much alone in our backwater corner of the galaxy.
TWiT Space correspondent Rod Pyle joins Leo to talk about an artificial signal discovered this week, coming from Alpha Centauri. The possibility is that the signals are coming from an advanced civilization out in the universe. The evidence is certainly interesting. The signals were picked up by SETI (Search for Extra-Terrestrial Intelligence) and points to being a manmade signal from our nearest galactic neighbor Proxima B. And at 982 Mhz, it points to a technological, not natural candidate.
Rod joins Leo to talk about the SpaceX Starship test that happened this week. Starship SN8 worked all the way to the landing, where it crashed and burned. But Rod Pyle says that it accomplished all the test goals it set out to do, and it's on to SN9 now. Rod says that SpaceX will fly crewless with starship for several years before building the larger, crewed version of Starship for a flight to Mars.
Our rocketman Rod Pyle joins Leo to talk about a recent Japanese probe that landed on an asteroid, scooped up a rock sample, and returned it to earth. The mission was HyaBusa 2 and it landed yesterday. The asteroid is an ancient chunk of our solar system which could contain the building blocks on how life was created on earth and what the solar system is made of.
China is also on a sample return mission, with a probe on the moon. It should bring back 5 pounds of the lunar surface in about two weeks.
