The space industry treats the sky as a place to dump what it no longer wants. We must develop a new model of accountability

On 5 August, a piece of a derelict SpaceX rocket traveling at 5,400 miles an hour met with the moon and punched a fresh hole into it near Einstein Crater. Astronomers were thrilled. The European Southern Observatory caught sodium and lithium flaring in the debris plume and called it a bonus. The media called it a light show. Nobody was physically hurt, so nobody is responsible, and within a week the story was gone.

I have spent 20 years tracking the junk humanity leaves behind in space for a living, and I want to tell you plainly what that crater actually is: a receipt. It’s what you get when an entire industry treats the sky, and now the moon, as a place to dump what it no longer wants, and calls the dumping “normal operations” or “space exploration”.

Since it was stripped of planetary status, Pluto’s defenders have been fighting the decision – and they’re only getting more passionate

Twenty years ago, Pluto got demoted. After a vote by the International Astronomical Union (IAU) in August 2006, Pluto was relegated from major planet to dwarf planet status. Our solar system dropped from nine planets to eight. At the time, many scientists were unhappy with the decision. Two decades on, the debate is, if anything, even more polarised.

“The definition of a planet they created, you can’t use it at all,” says Philip Metzger, the director of the Stephen W Hawking Centre for Microgravity Research and Education at the University of Central Florida. “It makes the definition of a planet completely non-useful in science.”
