Latest Orbit insertion Stories
After a spectacular launch, the Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft was placed by the Minotaur V launch vehicle into an elliptic orbit around Earth, as the start of our journey to the moon.
MESSENGER successfully completed an orbit-correction maneuver on March 2 to lower its periapsis altitude - the lowest point of MESSENGER's orbit about Mercury relative to the planet's surface - from 405 to 200 kilometers (251 to 124 miles).
On May 6th, MESSENGER began its 100th orbit around Mercury.
NIAGARA FALLS, N.Y., March 23, 2011 /PRNewswire/ -- AMPAC-ISP CORP., American Pacific Corporation's (Nasdaq: APFC) wholly-owned in-space propulsion subsidiary (AMPAC-ISP), reported that their LEROS 1b bipropellant engine (LEROS 1b) fired for nearly fifteen minutes in the early hours on March 18, 2011 to slow the MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) spacecraft and place it into orbit around Mercury.
Nine days from now â€“ on March 17 â€“ the MESSENGER spacecraft will execute a 15-minute maneuver that will place it into orbit about Mercury, making it the first craft ever to do so, and initiating a one-year science campaign to understand the innermost planet.
After more than a dozen laps through the inner solar system, NASA's MESSENGER spacecraft will move into orbit around Mercury on March 17, 2011.
One hundred days from now, MESSENGER will execute a 15-minute maneuver that will place the spacecraft into orbit about Mercury, making it the first craft ever to do so, and initiating a one-year science campaign to understand the innermost planet.
One year from today â€” starting at 12:45 am UTC â€” MESSENGER will transition from orbiting the Sun to being the first spacecraft ever to orbit the planet Mercury.
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.
MESSENGER completed the second part of a two-part deep-space maneuver today, providing the remaining 10% velocity change needed to place the probe on course to fly by Mercury for the third time in September 2009.
