The most recent installment of NPR's Brave New Workers A NASA Astronaut Stays In Orbit With SpaceX And Boeing (article & podcast) covers Astronaut Sunita Williams extremely cool new job.
She's continued her career in space on Earth as a member of NASA's Commercial Crew Transportation Capability (CCtCap), a group of veteran astronauts that works with privately-held companies like SpaceX and Boeing to develop spacecrafts.
Part of her job is to verify that the companies' spacecraft can launch, maneuver in orbit and dock to stationary spacecraft like the ISS. NASA announced the CCtCap in 2015 as part of "the Obama Administration's plan to partner with U.S. industry to transport astronauts to space, create good-paying American jobs and end the nation's sole reliance on Russia for space travel."
"This is really different from my old job, you know," Williams said. When she became an astronaut, the shuttle was already laid out. "It was all documented and out there, and [I] went through classes to understand all the systems," she said. "The plan was there, and you had to get this, this and this done before you could go fly out in space."
The space machinery of private companies that Williams now supports are still works-in-progress. "They don't really have training systems established for them yet," she said. "We're sort of creating that right now with the folks at the companies." That means deciding what things are important for astronauts to know — "classic things like getting in your seat, reach[ing] all the controls," she said. "We're establishing all that with the companies right now." Her contributions have helped to build the Boeing CST-100 Starliner and SpaceX Dragon.
The photo shown in the article is also shown below. On their left wrist are two devices. One is obviously a watch, the other looks more specialized and non-commercial.
Question(s): What is it? What does it do? What's inside it? Who made it?
It looks like an electronic key for a car, but everyone knows there are no cars in orbit! Well, not anymore at least ;-) https://www.whereisroadster.com/
