Are interferometers the future of telescopes? Can we aim at stars by knowing only where they were billions of years ago? Is the Apophis asteroid still dangerous? And in Q&A+, can we just sent the SG-1 to it?
00:00 Intro

00:37 [@PerryM-vy4fe] Are Interferometers the future of space telescopes?

03:36 [@Frosty.Winnipeg] If we can see stars a billion light years away can we guesstimate where they are now?

05:29 [@PeterYannick] Where do we have to aim a laser if we want to sent a message to Alpha Centauri?

07:19 [@andrewczski1969] Apophis in 2029 can shut the WHOLE show down, no?

12:43 [@kairon156] Are there any plans on getting rock samples from Mar's moons?

14:25 [@Frosty.Winnipeg] Can’t we just send SG-1 to face Apophis?

If SpaceX no longer want Falcon 9 and Crew Dragon, why won't NASA just buy them for themselves? What would a perfect space station look like? What is being done to improve the deep space network? And in Q&A+, finally, a Lagrange Point question.

Why do star shades look like flowers? Is Mars colonization just a Ponzi Scheme? Why would it be worth doing? And on Q&A+, should you scream into the void?
00:00 Intro

00:23 [@silasmiller4417] Why are renders of orbital star shades shaped like flower pedals?

05:37 [@illyakuryakin5024] Anyone notice no one is talking about the Ponzi scheme called "Mars Colonization" anymore?

12:13 [@illyakuryakin5024] why would it be so "amazing"?

17:42 [@Alienalloy] If I scream in the vacuum of space have I gone beyond compony health and safety procedures so already a lost cause?

Solar sails are great. It's a propulsion method that doesn't require carrying fuel. But the need to be really big to be efficient. How do you fold them on Earth and unfold in space? What's a reliable way to do that? NASA recently awarded a NIAC grant specifically for that.
