"Signal stable, estimated atmospheric penetration depth is 150 kilometers!"
The atmospheric thickness of Venus is far less than that of Earth, only about 250 kilometers.
The flyby craft will separate from the Morning Star No.1 the moment it contacts the atmosphere, using a small gas engine to enter a water-skimming trajectory, capable of descending to about 90 kilometers in altitude before bouncing back up. However, based on the probe's autonomous judgment, it plans to dive to a depth of 100 kilometers for sampling.
This height is roughly situated between the thermosphere and the exosphere, with air pressure not exceeding 10 pascals. If Venusians were to observe from the ground, they might see a brief, twinkling meteor.
Tai Bai, already in orbit, is also assisting with monitoring, its great mass providing precise and powerful shortwave transmitters, and has established stable connections with the two separating probes.
"Flyby separation!"
"Altitude 270 kilometers!"
