The change is a blow to the astronomers and planetary scientists who used the information to track space rocks, especially those that burn up over the oceans or in other remote locations. “These systems are extremely useful,” says Peter Brown, an astronomer at the University of Western Ontario in London, Canada. “I think the scientific community benefited enormously.”
The USAF later said the data would be made available again, but I don’t know if that happened. If it did, it may well be a better source than the data the Guardian worked from.
