Gravity Assist

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. ❋ Unknown (2009)

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. ❋ Unknown (2005)

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. ❋ Unknown (2003)

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. ❋ Unknown (2010)

So much gravity, in fact, that they often need to use wheelchairs or other gravity-assist devices. ❋ Unknown (2010)

Engineers say the gravity-assist will increase Rosetta's speed by 3. 6km/s with respect to the Sun. ❋ Unknown (2009)

Engineers say the gravity-assist will have increased Rosetta's speed by almost 4km/s with respect to the Sun. ❋ Unknown (2009)

The gravity-assist will increase the spacecraft's speed by 3.6 km/s with respect to the Sun. Instruments in Action ❋ Unknown (2009)

"planetary gravity-assist manoeuvres" will see BepiColombo swing by Venus, Earth and Mercury. ❋ Unknown (2010)

Gravity Assist will [help] you [defecate] [easily]. ❋ Shiine-1 (2022)
