Dear Cheap Astronomy Ep. 075: Practicalities

Hosted by Steve Nerlich. – What do you know about satellite servicing. So, here’s a new twist on the space junk story. Remember, there’s two main populations of space junk, one in low earth orbit, which includes various rocket stages, decommissioned surveillance satellites and miscellaneous debris all of which will eventually undergo orbital decay in years, decades or centuries.  – What would a multi-generational spacecraft be like?  It would probably look like the human race’s complete collection of moral dilemmas all packed into one sardine can. The premise here is that if we can't travel faster than light speed (or even close to it), the only way for people to reach other stellar systems is with a multi-generational spaceship.    We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
