There was a lawsuit many years ago that an airline pilot filed against NASA. He was upset that only military pilots would be considered to become astronaut pilots. NASA won, didn't change their procedures, and to this day, you still need to be military-trained and have served to be considered for a pilot astronaut position at NASA.

My boss had a pair loaned to him and I got to try them out briefly. The flicker wasn't noticeable much and the rendering and coordination with the image to the motion of one's head was very smooth. The images were full color, not red/blue like some old print version although they still produce and use those images routinely in science planning as well (...

Before the Navy Seals there were the Underwater Demolition Teams (UDT). They assisted the recovery of the space capsules. The Underwater Demolition Teams (UDT) were a special-purpose force established by the United States Navy during World War II. They came to be considered more elite and tactical during the Korean and Vietnam Wars. Their primary WWII ...

If we look to the speed of Voyager 2 relative to Jupiter, this maximum of this speed should occur at perijove. If distance to Jupiter increases after perijove the speed of Voyager in the jovian reference frame would decrease. But the transfer of energy from Jupiter to Voyager by gravity assist is not finished at perijove. If we use the reference frame of the ...

That's STS-134, the final mission of Endeavour. There is a higher quality video here but sadly it cuts away just as the vehicle enters the cloud deck. Lots of cool ascent video here from that mission but a quick skim didn't show the cloud deck penetration. There's a cool shot from the Shuttle ...

Manual rendezvous was tried first, in Gemini 4. It went badly, because orbital mechanics are very counter-intuitive. As GPO engineer Andre Meyer later remarked, "There is a good explanation for what went wrong with rendezvous." The crew, like everyone else at MSC, "just didn't understand or reason out the orbital mechanics involved. As a ...

NASA has been considering the idea of integrating HUDs into spacesuits for a while. This slide deck gives a decent overview of some of the ideas that the agency has been considering. NASA has also received suggestions from the public (for instance, via its Space Apps Challenge) on what a spacesuit HUD might look like. ESA has also conducted research into ...

The decision to have a complicated computer that controlled many of the spacecraft functions was made in 1961, very early in the Apollo program. From NASA's history, Computers On Board The Apollo Spacecraft: The need for an on-board computer The presence of a computer in the Apollo spacecraft was justified for several reasons. Three were given early in the ...

The onboard computers were primarily provided for Guidance, Navigation, and Control (GNC). The mere act of starting and/or stopping a rocket engine burn is simple enough for humans to do. Figuring out when to start and stop that burn, and where to point the spacecraft during it, are not something humans are going to do unaided in an operational amount of ...

Line of sight maneuvers are not precise enough regarding the huge distance from Earth to the Moon. The mid course corrections were impossible without the calculations done by the computer. If course corrections far from the Moon are not precise, much more fuel is needed for corrections close to the moon. Orbital rendezvous maneuvers are much more difficult ...

Partial answer: From this ESA-provided diagram (source), and corroborated by everything I've run across: It's certain that NASA will be building both the lander & ascent vehicle. But we already knew that--who exactly will be building it? Most of the papers I've read regarding the MAV design specifically are authored out of Huntsville, so it seems likely ...

Ed Fendell, a controller in Houston was controlling the rover camera. It’s in the EVA-3 mission logs. https://www.hq.nasa.gov/alsj/a15/a15.clsout3.html
