Summary
The UK’s oldest satellite, Skynet-1A, launched in 1969, has mysteriously shifted from its original orbit over Africa to a high-risk position over the Americas.
It’s suspected that in the 1970s, Skynet-1A was intentionally moved west, possibly by U.S. controllers, but records confirming who made this decision and why are missing.
Now inactive, the satellite poses collision risks to active satellites, as it occupies a congested orbit at 105 degrees West longitude.
The UK may eventually need to consider relocating Skynet-1A or removing it altogether to mitigate risks from space debris.
I thought we had a good idea what was where in orbit. How is this a sudden surprise? I had first read it thinking that it had drifted recently for some reason, but it’s been in that place for 50 years. I get that as more satellites go up things become more risky, but this should have been a known problem a long time ago.
The way I read it is that it’s old news, but who did it still isn’t publicized. I’m sure some people know who did it, just not the public.
Given that it was done in the 70s, probably by people who were at least in their 40s at the time, it’s very possible that they’re all dead by now.
