A Supercomputer on the Moon to Direct Deep Space Traffic

Hugh Pickens writes (1984118) writes | about 2 years ago

Moon 1

Hugh Pickens writes writes "NASA currently controls its deep space missions through a network of 13 giant antennas in California, Spain and Australia known as the Deep Space Network (DSN) but the network is obsolete and just not up to the job of transmitting the growing workload of extra-terrestrial data from deep space missions. That's why Ouliang Chang has proposed building a massive supercomputer in a deep dark crater on the side of the moon facing away from Earth and all of its electromagnetic chatter. Nuclear-powered, it would accept signals from space, store them, process them if needed and then relay the data back to Earth as time and bandwidth allows. The supercomputer would run in frigid regions near one of the moon’s poles where cold temperatures would make cooling the supercomputer easier, and would communicate with spaceships and earth using a system of inflatable, steerable antennas that would hang suspended over moon craters, giving the Deep Space Network a second focal point away from earth. As well as boosting humanity's space-borne communication abilities, Chang's presentation at a space conference (PDF) in Pasadena, California also suggests that the moon-based dishes could work in unison with those on Earth to perform very-long-baseline interferometry, which allows multiple telescopes to be combined to emulate one huge telescope. Best of all the project has the potential to excite the imagination of future spacegoers and get men back on the moon."

Sure but... (0)

Sure but how?

Arrays of terrestrial antennas on earth could do the same job.

With the signal levels involved in GPS, Bluetooth and cell networks it is not a reach.
Most regions already have acres of old generation dishes onced needed for cable feeds.
This history would solve zoning because all that is needed is pointing and data feed
upgrades all invisible to neighbors I.e. nothing would look like I changed.

This could give continental dimensions to the synthetic aperture.

Yet with robots and 3D printing tech a robot army on the moon coul fuse moon dust to do this.
Just not the electronics.

And who would make a 7x24x365.25 SLA house call?
