| The current controversy concerning Cassini's upcoming Earth swingby centers on the risk of the spacecraft accidentally re-entering the Earth's atmosphere. |
|
| Of course, nothing eventful happened with our Earth swingby. |
|
| Approximately one month later, the second observatory will be redirected after another lunar swingby to its position ahead of Earth. |
|
| The swingby will provide exactly the boost Rosetta needs to continue into the outer Solar System. |
|
| These swingby manoeuvres were a way of saving fuel while using the gravity of planets to boost speed. |
|
| This will be the third Earth swingby, the last of Rosetta's four planetary gravity assists. |
|
| Following ISON's solar swingby, the comet will depart the sun and move toward Earth, appearing in morning twilight through December. |
|
| The spacecraft will make a comprehensive study of the solar wind, utilizing dual lunar swingby orbits to sample regions close to and farther away from the Earth. |
