Kosmos 1805
Kosmos 1805 (
Overview
Kosmos 1805 was launched at 07:30 UTC on December 10, 1986 atop a
Near-collision with Fermi Space Observatory
On April 30, 2013, it was announced that Fermi space observatory narrowly avoided a collision with Kosmos 1805 one year previous, in April 2012. Orbital predictions several days earlier indicated that the two satellites were expected to occupy the same point in space within 30 milliseconds of each other. On April 3, 2012 telescope operators decided to stow the satellite's high-gain parabolic antenna, rotate the solar panels out of the way and fire Fermi's rocket thrusters for one second to move it out of the way. Even though the thrusters had been idle since the telescope had been placed in orbit nearly five years earlier, they worked correctly. After the danger passed, Fermi initiated a one-second thruster burn to return to position.[1]
