She asked people what vanity license plate they'd get. Since I've had the handle CERisE since around '86 or so, that was the logical choice.
A long while ago, I ran a page on geocities which had a listing of other CERISEs. One of the more interesting ones was a French satellite
I happened to get in touch with one of the folks involved. As it turns out CERISE was one half of the first "natural" collision of artificial Earth satellites. "Natural" is a nicer way of saying "unplanned" or "accidental".
On 24th July 1996 the satellite was hit by a fragment of Ariane V16 which launched Spot 1 The relative velocity of the collision was 14.8 km/s. Part of the gravity-gradient boom was detached at 3.1 m of its base (was 6 m long).
The cool part was that they were able to upload new software to correct despite the loss of its stabiliser.
