Happy 51st B'day to Deep Space Station 43 (DSS43)! 📡

One of my fav antennas, and at 70m diameter, the largest steerable antenna in the Southern Hemisphere, located at @canberradsn

DSS43 keeps in touch with super important missions like Voyager2, only acquirable from this station!

#NASA 📆 July 12, 2023 #DSS23 started in 📆 February 2021 at the Goldstone, #California, #DSN Complex (with #OpticalCommunication
capabilities, which will be critical to communicate with #astronauts 👨‍🚀👩‍🚀 traveling to #Mars 🔴). NASA cannot use #RadioFrequency communications to carry higher data rates like those required for Mars without increasing
the size of its antennas 📡 or power of its radio transmitters. Therefore, the Agency is developing #optical communications (use
of light as a means of transmitting information through #lasers) https://oig.nasa.gov/docs/IG-23-016.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
