Astronomy in the News: Mar 20, 2000
- A rare meteorite, called a carbonaceous chondrite,
is recovered in pristine condition a few days
after its fall to earth. We may learn much about
the composition of the nebula from which the
Sun and Earth formed from it.
- NEAR spacecraft
is in orbit around Eros
- Mars Global Surveyor
detects dust devils on the planet's surface ,
which create dark streaks of dust in their wake
- The Iridium constellation of communications satellites
may be de-orbited because its operators are going
bankrupt.
This would be good news for some astronomers, but
bad news for people who like to look for
Iridium flares.
