Something I've always wondered about controlling probes like Juno in deep space... Are the commands that control the engine burn sent to the spacecraft from Earth and executed as they're received, or was the precise start time of the burn programmed in Juno's computer ahead of time and executed pretty much autonomously?

No one who uses spaces actually manually hits the spacebar. In their IDE, they choose Preferences > Tab Policy > Insert Spaces and use the tab key normally.

The best pro-spaces argument I've heard is that it preserves formatting across different machines and editors. A space is always a space, but a tab can be of varying width depending on the editor's configuration.

Sometimes a line will be indented with 3 spaces. Sometimes 4. Sometimes 7

I just threw up in my mouth a little.

For the veteran astronauts: from your testing and training so far, what's the biggest difference you notice in the Starliner/Dragon capsules compared to other spacecraft you've flown in, such as the Shuttle or Soyuz?

The first few launches of SLS will use engines originally built for the space shuttle, I'm guessing some time in the 2000`s. What's the process like to store them and get them ready again for a flight? I'm guessing you can't just put a highly complex rocket engine on a shelf and dust it off for a launch 10 years later (or can you!?)
