Flyby Anomalies Explained? - Universe Today

WebA gravity assist, gravity assist maneuver, swing-by, or generally a gravitational slingshot in orbital mechanics, is a type of spaceflight flyby which makes use of the relative movement (e.g. orbit around the Sun) and gravity of a planet or other astronomical object to alter the path and speed of a spacecraft, typically to save propellant and reduce expense. WebWe make preliminary estimates to assess whether the recently reported flyby anomaly can be attributed to dark matter interactions.
