Gravity Assist
A gravity assist (or swing-by) maneuver uses the gravitational field of a planet or other celestial body to alter a spacecraft's trajectory and velocity without expending fuel. Discovered by Michael Minovitch at JPL in 1961, this technique is crucial for reaching distant planets economically. It works by exploiting the relative motion between the spacecraft, the assisting body, and the Sun.
Rekodi ya chanzo
Nukuu zimehamishwa kwa uhalisi kutoka kwa rekodi ya chanzo cha mbinu. Hakuna uthibitisho wa kiwango cha dai unaodokezwa kutoka kwao.

Madai yaliyotunzwa
Madai yamehifadhiwa katika daftari la ushahidi, kila moja ikiwa na tathmini yake.
Mwonekano huu haubuni tathmini ya dai wakati daftari haina yoyote.
Mbinu zinazohusiana
Zilizotengenezwa kutoka kwa grafu ya mbinu na kuonyeshwa kama uhusiano uliopendekezwa na mashine — hakuna dai la ushahidi linalodokezwa.
