An ageing American spy satellite has broken apart in orbit, renewing concern about the communications and internet satellites sharing the same altitude.
What is known
According to the US military, the satellite USA 32 — known in the Cold War by the code name Farrah 3 and launched in 1988 — fragmented suddenly in low Earth orbit on 13 September, after 38 years in space.
An investigation into the cause continues. Spaceweather.com, run by the astronomer Tony Phillips, suggests a pressurised tank or a battery inside the spacecraft may have ruptured. A collision with debris or a meteoroid cannot be ruled out, because the satellite sat in a busy orbit.
Phillips notes that more than 200 satellites operate close to that altitude, including active spacecraft of the Iris Next constellation. CNN reported no evidence that the satellite was deliberately targeted by an anti-satellite weapon; Russia destroyed an old Soviet satellite with a missile in 2021, drawing wide criticism.
What it means in Bangladesh
Bangabandhu-1 sits in geostationary orbit, about 36,000km up, and is not at risk from a break-up in low Earth orbit. That is the straightforward answer, and it is also where the reassurance ends.
Almost everything else Bangladesh depends on from space is in the crowded shell this satellite broke apart in. The imagery used for flood mapping in the haor and for cyclone tracking in the Bay comes from low-orbit satellites. So does the Earth-observation data behind agricultural and embankment monitoring. So does Starlink, which began operating here this year and which puts its spacecraft in exactly that region.
The reason an individual break-up matters more than its own debris is cumulative. Fragments do not fall quickly at that altitude; they spread into a band and each piece becomes a thing that can cause the next break-up. That cascade has a name, the Kessler syndrome, and it is slow and effectively irreversible.
For a country that uses space services without launching anything, there is no technical mitigation available. There is a diplomatic one, and it is unglamorous: the rules on end-of-life disposal and debris liability are written in bodies like the UN Committee on the Peaceful Uses of Outer Space, where small states have a vote and almost never use it. Bangladesh buys satellite capacity, imagery and connectivity; it has a direct interest in whether a 1988 spacecraft was allowed to stay up there with a pressurised tank still in it.
The warning is worth taking plainly. Nothing was shot down here. A satellite older than most of the country's population simply came apart on its own.
