• China and Russia are experimenting with stealth technologies to evade radar and telescopes.
• Shiyan-24 satellites have different radar cross sections.
• The Chinese military has been shaping microsatellites to make them harder to spot.
• The PLA published a research paper on a metallic satellite with a low radar cross section.

This development may indicate a growing concern about aerial threats in space. The use of stealth technologies could make it harder for the US to detect and track satellites, potentially impacting national security. The focus on low-observable technologies suggests a long-term strategy to gain an advantage in space-based operations.
