I am now personally accountable for some of the solar system's interplanetary debris.
The ringed world of Saturn is almost a year of interplanetary travel away.
Its principal responsibilities are to support interplanetary spacecraft missions and radio and radar astronomy observations.
Fragments of asteroids and comets pervade interplanetary space.
In interplanetary space, the fast wind often collides with the slow wind.
If plans for interplanetary human space missions are to be realised, with a return journey of up to a couple of years, future astronauts will have to be able to act during a medical emergency.
In addition, most upper stages that are used to propel systems to high orbits or even into interplanetary trajectories are also solid-fuel systems.
The Judges would select a developing planet that was about to develop interplanetary travel to which to send a subject for five years.
But on interplanetary missions, astronauts will experience this damaging radiation full force.
For interplanetary missions, such windows are much stricter than for satellites orbiting the Earth.
