At 12:15 p.m. CDT (15:15 UTC) on Monday, September 16, 2024, we’ll talk about the human impacts of spaceflight - the environmental, social and political consequences - with astrophysicist Jonathan McDowell, a spaceflight historian and author of Jonathan’s Space Report. He's increasingly concerned the downside of humanity’s presence in Earth-orbit.
In 2023, humanity flung 2,664 objects beyond Earth’s atmosphere. Almost all of them are still up there. And they're not alone. NASA’s Orbital Debris Program Office estimates more than 25,000 objects 4 inches (10 cm) or larger are drifting free in orbit. Nearly 500,000 smaller bits of space junk - 0.4 to 4 inches (1-10 cm) - and 100 million microscopic particles pepper low Earth orbit.
Along the way, a Chinese company almost dropped a giant rocket booster on a major city and SpaceX blew a hole in the atmosphere when its Starship exploded during a test flight.
Are we trashing space? What can be done about it? And who's in charge up there anyway?
