HI THERE, HALLEY!
The shuttle disaster has turned
attention away from the flgtilla of
probes heading towards Halley's comet.
But today the American Pioneer 12 will
pass withing 24 million miles of it
─ the closest a US craft will get.
That doesn't compare too well with the
Euro-probe Giotto (due to get within
300 miles) but Pioneer was not intended
as a comet-studier. Launched in 1978 to
look at Venus, it was re-aligned by
NASA to make comet observations.
