jfc, I was having lunch so I thought I'd put on #Disney+ #Crater for some mild, family SF fun...

... it's ending now and I am WEEPING...

Why does this kids' film have more heart than a dozen supposedly adult blockbusters?

My heart really can't take the ending. 😢

With #disney being a #reboot #machine as of late, #Crater is a very refreshing #original story that modernizes stand by me for new audiences. A #stellar visual journey with an ending you won't forget so easily.

Challenges of #SpaceNavigation : If #Earth were the size of a softball, the #ISS would be orbiting just above the seams, the #Moon would be a #marble about 2 meters away, and #Mars would be 1.2 to 2.4 kilometers away. The targets are small and moving. https://timeandnavigation.si.edu/navigating-space/challenges

Chris Potts compared the target requirements of #landing the #Spirit rover inside a specific #crater on Mars 🔴 to being able to shoot a #basketball 🏀 through a hoop 9000 miles away.
Since there’s no #GPS in outer space, navigators process the radiometric tracking data received from the #DeepSpaceNetwork (#DSN) to determine the #spacecraft’s #position and velocity. They also use optical data, where the spacecraft takes a picture of the star background to help refine the spacecraft’s trajectory https://www.universetoday.com/37934/the-navigators-how-we-fly-spacecraft-around-the-solar-system
