“ • A survey of Lake Michigan located at least 40 large craters on the lakebed.
• Initial studies highlighted the spots as unknown shapes, but additional research revealed the craters are filled with marine life.
• Researchers expect to investigate further, seeing how these craters formed and if they’re really sinkholes…"

Malapert A is a satellite crater to #Malapert, a 69 km #crater. The #IM1 landing site is about 300 km from the #Moon’s 🌙 south pole. https://www.intuitivemachines.com/_files/ugd/7c27f7_51f84ee63ea744a9b7312d17fefa9606.pdf

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
