isn't that stuff highly toxic?

The stage is pacified after MECO. This means dumping all residuals.

Having said that, it is still not advised to go near or handle such debris without proper guidance. Which is something local authorities try to communicate and enforce in the evacuated areas when there is a launch campaign in progress.

High-resolution images from the successful launch of LandProbe-4 01 (陆地探测四号01), which is a remote sensing satellite carrying a synthetic aperture radar. The launch marked the 483rd flight of the Long March series and the 35th Chinese launch this year.

what will it be used for? early warning? indo pacific monitoring? also, this geosar is geosynchronous synthetic aperture radar, not search and rescue, right?

I am curious if "陆地探测四号01" is a GEOCSAR or just an ordinary GEOSAR. The C in GEOCSAR stands for circular, meaning that the footprint of the satellite on the surface of earth is near circular, while ordinary GEOSAR's footprint is shape 8. GEOCSAR has higher coverage, resolution, more continious coverage, higher revisit frequency for non continious coverage area, and most importantly 3D imaging.

It would be interesting to find out. Different inclined orbits at that altitude have

XICHANG, Aug. 14 (Xinhua) -- China successfully launched a Kuaizhou-1A carrier rocket to send five new satellites into space from the Xichang Satellite Launch Center in southwest China's Sichuan Province on Monday.

The A to E satellites belonging to the Head-3 micro-satellite constellation were launched at 1:32 p.m. (Beijing Time), and entered the planned orbit successfully.

The satellites will mainly be used for providing commercial remote-sensing services.

The launch was the 27th mission undertaken with Kuaizhou-1A series rockets.

A progress update on the Hainan spaceport for commercial launches. Launch tower at Launchpad No.1 will be capped later this month, earthworks for launchpad No. 2 is almost complete, and the entire spaceport will be finished by the end of this year.

Progress update on the launchpad No. 1 of the Hainan Spaceport for Commercial Launches as well as new construction activities at the neighboring Wenchang launch center.
