Re-entry of the space junk is expected Saturday within an 18-hour window

Some Vandenberg Air Force Base members have been keeping a close eye on out-of-control debris from a Chinese rocket as they calculate as close as possible when and where the space junk might land.

GPS Next-Generation Operational Control System (OCX) Follow-On (OCX 3F).
The OCX 3F program is further future iteration of the GPS Enterprise Modernization effort. OCX comes in four blocks: 0, 1, 2 and now 3F. Only Block 0 is currently operative, though it does not “fly” the constellation, it only handles Launch and Early Orbit (LEO) operations and the on-orbit checkout of all GPS III satellites. I has done so for four GPS III satellites so far. A fifth launch is due in June.

Currently, all GPS satellites are controlled by the Operational Control System (OCS), which Lockheed Martin sustains until 2025, when OCX will start taking over. OCS now flies the more powerful GPS IIIs as well as older satellites and tasks, uploads and monitors the encrypted M-Code signals.

The United States Space Force is the newest branch of the American military, and as its name suggests, the most dependent upon high technology and forward thinking to carry out its mission. So it is perhaps no surprise that Dr. Joel Mozer, the space force’s chief scientist, would declare that we are at “the brink of the age of human augmentation,” while addressing an event at the Air Force Research Laboratory.
Mozer’s remarks suggest a wide view of what constitutes augmentation. He refers to more sophisticated modes of human-machine teaming, where robotic agents would be given ever-increasing amounts of autonomy to make decisions while reducing the workload of their human controllers to making only the highest-level strategic decisions. There is an active debate about the ethical, legal, and operational questions raised by outsourcing ever-more-significant decisions to machines, especially where those decisions might well involve taking human lives. But we are
