On June 17, Herschel's thrusters were activated and a burn was completed putting it into a different heliocentric orbit.
New Delhi, Muharram 27, 1435, Nov 30, 2013, SPA -- India's Mars-bound spacecraft is scheduled to complete a key manoeuvre to move out of the earth's orbit into a heliocentric orbit towards the Red Planet in the small hours of Sunday, Indian Space Research Organisation (ISRO) officials say, according to dpa.
This was the main manoeuvre in a series that ensured the satellite was boosted away from its operational orbit around the L2 Sun-Earth Lagrange Point and into a heliocentric orbit, further out and slower than Earth's.
But I think it's brought out the question that we aren't adequately cataloging the artificial junk that's being sent into heliocentric orbit.
Here, the asymmetric torques affect the system as a whole, leading to three possible end states: a long-lived, stable binary system; an escape leading to two asteroids sharing the same heliocentric orbit, but not mutually orbiting each other; or a gentle collision resulting in a contact binary, probably resembling 25143 Itokawa (recently visited by Japan's Hayabusa spacecraft).
A master list of candidates entering heliocentric orbit has been published on the Web.
For example, the census of known planetary-scale (read: rounded due to gravity) bodies in heliocentric orbit includes the four large terrestrial bodies, two giant planets, two ice giants, about 20 large asteroids, and hundreds of large Kuiper Belt objects (including Pluto).
Much like its namesake, the miner's daughter of folk legend, the spacecraft ended up "lost and gone forever" in heliocentric orbit.
These new observations likely rule out a retrograde orbit, but the arc of motion so far is still too short to determine an accurate heliocentric orbit.
The White House released various goals for federal research, development, deployment, operations, coordination and engagement of near-earth objects (NEOs), which includes asteroids or comets with heliocentric orbits that come close to or intersect our planet's orbit.
