Here's how scientists protect Earth from extraterrestrial germs

Dr. Daniel H. Anderson, an aerospace technologist and test director in the Nonsterile Nitrogen Processing Laboratory in the Lunar Receiving Laboratory at the Manned Spacecraft Center looks at much-discussed Apollo 14 basketball-size rock through a microscope. The two moon-exploring crew men of Apollo 14 brought back 90-odd pounds of lunar sample material from their two periods of extravehicular activity on the lunar surface in the Fra Mauro area.

For years, concerns about planetary protection have focused on preventing Earth from littering the solar system—sterilizing spacecraft and keeping astronauts under strict quarantine protocols. But as space agencies around the world gear up to bring more samples back from destinations such as asteroids, the moon, and Mars, scientists are once more considering the opposite prospect: What if we bring extraterrestrial germs back to Earth?

Many things are taking place:

Arecibo telescope's fall is indicative of global divide around funding science infrastructure

While drone footage captured the moment in excruciating detail, in truth, the disintegration of the telescope in Arecibo, Puerto Rico began far before this cinematic end.

It is tempting to blame the demise of Arecibo on the physical damage it sustained earlier in 2020, when an auxiliary metal cable snapped – perhaps a delayed consequence of Tropical Storm Isaias or the earthquakes that shook Puerto Rico . But Arecibo's downfall was, in reality, caused by years of financial struggles.

Ben Bova, Science Fiction Editor and Author, Is Dead at 88 - The New York Times

Ben Bova was a hard-science guy — and a passionate space program booster — and his visions of the future encompassed a dizzying range of technological advances (and resulting horrors or delights), from cloning to sex in space, climate change, the nuclear arms race, Martian colonies and the search for extraterrestrials. In newspaper articles, short stories and more than 100 books, he explored these and other knotty human problems.

Mr. Bova had a background in journalism and technical science writing, and his work was based in facts. He was determinedly not a fantasy author.
