A Very Complex Spacewalk Outside the Space Station on This Week @NASA – November 15, 2019
Some very complex work outside the space station, key milestones for our Artemis program, and a fitting tribute for an historic flyby … a few of the stories to tell you about – This Week at NASA!

Q&A 106: Do Geostationary Satellites Reenter The Atmosphere? And More...
In this week's questions show, I answer what will bring geostationary satellites back to Earth, if you could use the heat on Venus to power a rover, why are we so arrogant to believe that life formed only here on Earth, and more. 01:38 How long will geostatationary satellites survive?
04:31 Could you use the heat on Venus to power a rover?
05:50 Arrogant to think Earth is unique with life
07:33 What kinds of rocks are on Mars?
09:31 Perovskite solar panels on Earth?
11:27 Could there be planets with polar orbits?
13:13 SagA* % mass of the Milky Way
14:25 How do missions tackle micrometeorites?
17:05 Why doesn't a black hole turn into a regular object?
18:22 Why do sci-fi spacecraft move unrealistically in space?
21:11 What clocks will Martians use?
23:03 Could we search for dips in light to find Planet 9? Want to be part of the questions show? Ask a short question on any video on my channel. I gather a bunch up each week, and answer them here. Our Book is out!

How Can Infrared Light See Through Cosmic Dust?
How can scientists see into cloudy and dusty regions of space where stars form? They study a different kind of light—infrared—to learn about these sites. Credits: Produced by the Space Telescope Science Institute’s Office of Public Outreach. • Narration: Nicole Fonarow

NASA Attaches All Four RS-25 Engines to Artemis I Rocket Stage
Engineers and technicians at NASA’s Michoud Assembly Facility in New Orleans have attached all four RS-25 engines to the core stage for NASA’s Space Launch System (SLS) rocket that will help power the first Artemis mission to the Moon. To complete assembly of the rocket stage, crews are now integrating the propulsion and electrical systems within the structure. The completed core stage with all four RS-25 engines attached is the largest rocket stage NASA has built since the Saturn V stages for the Apollo Program that first sent Americans to the Moon. Engineers and technicians at Michoud attached the fourth RS-25 engine to the rocket stage Nov. 6 just one day after structurally mating the third engine. The first two RS-25 engines were structurally mated to the stage in October. Integration of the RS-25 engines to the recently attached engine section is a collaborative, multistep process for NASA and its partners Boeing, the core stage lead contractor, and Aerojet Rocketdyne, the RS-25 engines lead contractor. The four RS-25 engines, which are each roughly the size of a compact car, will together provide the SLS rocket 2 million of its 8.8 million pounds of maximum thrust.
