Sorry, no etymologies found.
Still, if there was something you really need to get rid of some isotope with no hope of beginning usable then using the VASIMAR to setup some gravity-assist with Venus and Mercury might help shed all that delta-V.
Mission design team members say that directing MESSENGER along just the right path above Earth will mean smaller course-correction maneuvers on the way to the 2006 gravity-assist flyby at Venus - ultimately saving fuel for later in the mission.
It used lunar gravity-assist to put it in orbit at the L2 point of the Sun-Earth system, 940,000 miles behind the Earth, with the Sun on the other side.
Because of the enormous distance of Saturn from the Earth, Cassini-Huygens's flight required four gravity-assist maneuvers - two of Venus, one of Earth and one of Jupiter - to gain enough speed to reach the outer solar system within the time frame required by the mission profile.
So much gravity, in fact, that they often need to use wheelchairs or other gravity-assist devices.
Engineers say the gravity-assist will increase Rosetta's speed by 3. 6km/s with respect to the Sun.
Engineers say the gravity-assist will have increased Rosetta's speed by almost 4km/s with respect to the Sun.
The gravity-assist will increase the spacecraft's speed by 3.6 km/s with respect to the Sun. Instruments in Action
"planetary gravity-assist manoeuvres" will see BepiColombo swing by Venus, Earth and Mercury.
