In one of my earlier posts I gave links for some of my favorite websites. This video I’m posting today is from NASA. It’s the most recent edition of their regular series SPACECAST WEEKLY. This video I found extremely fascinating because it talked about how astronauts train for space walks and the space suits they wear on these space walks. Also I loved the interview with a Canadian astronaut that spent time on the ISS. They also talk about the commercialization of space which is something I am personally concerned with. Because there is a big issue with space trash orbiting the Earth that is making it difficult to navigate launches into space etc. There is so much debris. It may not seem like much but it is getting worse. And with the commercialization of space I’m worried it will become exponentially worse because of all the satellites they are launching into space, especially all the so-called cube-sats or small satellites. For example SpaceX will soon set a record for most satellites launched on a single mission (143 total satellites – how is this not polluting space?)

So without further adieu here is SPACECAST WEEKLY. Enjoy.

and to pick up on my earlier comments about space debris. Will we eventually have so much debris that we will no longer be able to safely go into space? And will there eventually be so much debris that people in space may not be able to safely return to earth? Here’s an interesting documentary (fyi only the first half is about space junk – but the whole video is interesting).
