Any thoughts on two very recent space launches?
China launches yet another high-resolution Earth observation satellite, drops rocket debris
By Andrew Jones 2 days ago
While apparently routine, the mission had some new aspects to it. The Long March 3B rocket usually sends satellites towards geostationary orbits, which have an altitude of 22,236 miles (35,786 kilometers).
Sunday’s launch, however, saw the Long March 3B send a satellite into a much lower orbit — sun-synchronous orbit (SSO), around 310 miles (500 km) up, for the first time.

Delta IV Heavy Launches Long-Delayed NROL-44 Mission
By Ben Evans, on December 10th, 2020
It was the 12th launch of a Heavy since December 2004, marking the beginning of the end for an impressive rocket which has now lifted eight classified NRO payloads, NASA’s Parker Solar Probe, the final Defense Support Program (DSP) early-warning satellite and the inaugural voyage of the Orion deep-space exploration vehicle. But tonight’s mission with NROL-44, despite all the media attention it has received for the wrong reasons since August, is completely shrouded in mystery.
Judging from the Heavy’s lifting credentials—about 63,470 pounds (28,790 kg) to low-Earth orbit and up to 31,350 pounds (14,220 kg) to geostationary altitude—it would appear that NROL-44 is a heavyweight payload with a particularly high-energy-orbit requirement. It has been suggested that it may be an Advanced Orion/Mentor signals-intelligence satellite, perhaps weighing as much as 11,500 pounds (5,200 kg) and bound for a geostationary “slot” some 22,600 miles (35,900 km) above the Home Planet.

This is a space force launch BTW:
