Latest Lissajous orbit Stories
Beginning today, ESA's Planck satellite will carry out a critical mid-course maneuver that will place the satellite on its final trajectory for arrival at L2, the second Lagrange point of the Sun-Earth system, early in July. The maneuver is scheduled to begin at 19:28 CEST on June 5 2009, and will last for up to 30 hours. Planck's main thrusters will conduct repeated 'pulse burns' during this time, switching on then off for 6 seconds every minute. This pulse-burn technique is necessary...
The European Space Agency says the commissioning of scientific instruments and subsystems aboard its Herschel and Planck spacecraft has started. The two space observatories were lifted into orbit aboard an Ariane 5 rocket last week from the French spaceport at Kourou, French Guiana. Scientists said Herschel and Planck were functioning nominally and are now en route to their final orbits around the second Lagrange point, a spot in space know as L2, approximately 932,000 miles from Earth....
