17 November 2021 Current Affairs:Russia tested a direct-ascent anti-satellite (DA-ASAT) missile on 15 November.

The DA-ASAT missile collided with the Russian spacecraft COSMOS 1408, resulting in a debris field in low-Earth orbit.
So far, this test has produced around 1500 pieces of trackable orbital debris.
In subsequent experiments, it will create hundreds of thousands of particles of smaller orbital debris.
According to USSPACECOM’s first estimate, the debris will linger in orbit for years. As a result, the crew of the International Space Station is in grave danger.
The trajectory of debris is constantly monitored by USSPACECOM. It will ensure that all space-faring nations have access to the information they need to protect their on-orbit operations.

DA-ASAT Test by Russia:
The PL-19 Nudol, Russia’s first direct ascent anti-satellite missile, was successfully test-fired on November 18, 2015.
In May 2016, Russia tested the Nudol for the second time. The “Plesetsk cosmodrome test launch site,” located 805 kilometres north of Moscow, launched Nudol.
