back to article Chunks of deorbiting ESA satellite are expected to reach the ground

ESA's ERS-2 satellite is heading back to Earth this week and some substantial fragments are likely to survive re-entry, although the chances of anyone being injured by a hunk of space junk are vanishingly small. The UK Space Agency (UKSA) posted some images of the doomed European Remote Sensing (ERS-2) satellite at the end of …

    Those one in 100 billion chances happen all the time.

      Depends if it's 1 in 100 Billion chance of *someone* getting hit, or does that apply to every human on the planet... in which case there's about a 1 in 13 chance that someone will get hit?

        It's in pretty much a polar orbit, so everyone gets at least one chance to be hit.

        1 in 13 per year

        The actual statement on the website is "The annual risk of an individual human being injured by space debris is under 1 in 100 billion."

        So it is about a 1 in 13 chance per year that someone will get injured (or maybe a bit less, as multiple people can get hit in the same year).

        I don't know where they got the figures from, but they've found some reassuring generic figures, rather than work out the chances of being injured by these particular two tonnes of junk.

        Most of us here on earth are far more likely to be injured by a two tonne machine on wheels than one falling from the sky, partly because there are far more of them about.

          "... Most of us here on earth are far more likely to be injured by a two tonne machine on wheels than one falling from the sky, partly because there are far more of them about."

          And almost all of us are at that same altitude.

      Only when there are 100 billion events that "happen all the time".

      As far as I am aware there is only one satellite that is deorbiting.

        Are you aware that they are all deorbiting or burning limited fuel to maintain orbit?

    If you'd asked me ten minutes ago...

    ... I would have sworn that a drummer from Spinal Tap was killed by a re-entering satellite. However, I can't find any reference to this event.

    It is possible that my source was the commentary track from the 1998 DVD, but is looking more likely that just imagined it.

      I thought he either spontaneously combusted or choked on vomit (although they didn’t specify whose vomit). They've had so many drummers though that if a satellite strike hasn’t already taken one out it would be a good bet for the future.

      Don't know about the Spinal Tap guy, but Maggie O'Connell's boyfriend was killed by a falling satellite in Northern Exposure - that was a particularly hardy piece of kit, as it still had its antennae intact at the funeral (they just don't make 'em like that anymore).

        Ahhhhh, thank you @thatoneinthecorner... Yeah, I enjoyed Northern Exposure back in nineties, prior to my first viewing of Spinal Tap. That's where I got the idea from. You've eased my itchy brain.

        They had some good funerals on Northern Exposure, I enjoyed the one with the trebuchet launching the coffin into the lake.

        The internet tells me that as of last month it is a available to stream for the first time, after some longstanding issues around rights have been resolved.

      I remember the original UK One Off film.

      The US remake\series I was unfortunate to see half a episode of, while drunk at 4am having been up for by that time about 48 hours straight, after coming off a oil rig in the North Sea & unable to get to sleep.

      It didn't help.

      ...and weren't the MH scriptwriters clever, as they successfully predicted "blipverts" - very short duration adverts that appear without warning on TV programmes.

      And gawd knows how many ears later in 2024, we have YouTube, NetFlix, Prime, Disney, TikTok all happily wasting our time, by screening videos about stuff we are not interested in (although thankfully, there does not appear to be an increase in deaths caused by watching adverts).

    A bit more seriously

    It's slightly sad for me - I'm now well and truly retired, but back in the late 80s and early 90s I was a very minor part of the UK science team to design data processing algorithms for the UK processing facility for ERS-1 and 2.

    A bit more precision required

    "...will end up in the ocean."

    Umm, Which ocean did you have in mind? There are at least 6 that I can think of, and numerous large 'Seas'.

    "Having used up the last of the fuel, the mission officially ended..."

    While IANAAstrophysicist, why not deorbit this device while they still had fuel and could actually control, to a larger extent, where on Earth (literally) it was going to splash down?

      Re: A bit more precision required

      I'm guessing at the time that was the extent of the end of life plan. Earn revenue until you are nearly out of station keeping fuel and then use the remaining fumes to park it out of the way of the next generation that needs to occupy that orbital position. What happens after that is Someone Else's Problem. They did say the mission officially ended in 2011...
