What is the Double Slingshot Maneuver?
- The JUICE probe will first use the moon’s gravity to set itself on the correct trajectory towards Earth.
- Immediately after, it will use Earth’s gravity to slow down and redirect towards Venus and, eventually, Jupiter.
Significance of the Gravity Assist
- This technique, used for decades in space exploration, involves using a planet or moon’s gravity to alter the speed or direction of a spacecraft.
- It is unique as it involves back-to-back gravity assists using both the moon and Earth’s gravity, which has never been attempted before.
PYQ:[2020] The experiment will employ a trio of spacecraft flying in formation in the shape of an equilateral triangle that has sides one million kilometres long, with lasers shining between the craft.” The experiment in question refers to (a) Voyager-2 (b) New Horizons (c) LISA Pathfinder (d) Evolved LISA |
