I'm reposting this from last year and adding a great article about our consumer involvement in the search for alien life/outer space beings etc. very nicely done!
Astronomers
no longer need your personal computers to search for alien life!
A research project that lets the public participate in the
search for intelligent alien life is coming to an end after 21 years. That's because the Search for Extraterrestrial Intelligence at Home (SETI@home) project has collected a massive amount of data over the last two decades — and now it's time to get to work analyzing it. Founded in May 1999 by researchers at UC Berkeley, the project used radio telescopes to identify potential radio signals from space. Processing those transmissions required huge amounts of computing power, so millions of volunteers downloaded the SETI@home software on their personal computers, each taking on small chunks of data, working together like a supercomputer.
https://mashable.com/article/seti-at-home-shuts-down-aliens/The millions of people who, over the past two decades, donated their home computers' processing power to the SETI@home search for extraterrestrial intelligence no longer need concern themselves with such matters. The project, which launched in 1999 with the goal of using the world's idle computing power to analyze scientific data and maybe find signs of alien life,
will officially stop sending out work requests on March 31.

My original thread included this:
India used an indigenously developed ballistic missile interceptor to destroy one of its own satellites at a height of 300 km (186 miles), in a test aimed at boosting its defenses in space. India's top defense scientist said the debris would burn up in 45 days.
In 2007, China destroyed a satellite in a polar orbit, creating the largest orbital debris cloud in history, with more than 3,000 objects, according to the Secure World Foundation. Since the impact altitude exceeded 800 km (500 miles), many of the resulting scraps stayed in orbit.
"We will continue to closely monitor the remaining debris from India's ASAT test to ensure the safety of assets on-orbit and human spaceflight activities such as the International Space Station," said Garrett Marquis, a National Security Council spokesman.
Marquis said the United States remained committed to working with all nations to "mitigate the operational effects of orbital debris."
"As part of our strategic partnership, the United States will continue close engagements with India on shared interests in space," he added, listing areas that included "safety and security" as well as human space exploration.
