|
In the case of the solar wind, V is the wind speed and B the interplanetary magnetic field. |
|
This different behavior is mainly due to the interaction of the interplanetary medium with the surface of the asteroids. |
|
This surface is deteriorated by the solar wind and the micrometeorites present in the interplanetary medium. |

|
The solar system also consists of many various icy bodies, and vast amounts of nebula, gas and dust known as the interplanetary medium. |
|
The plan is to mine asteroids to be used on Earth and for interplanetary travel. |
|
But a vast amount of it will be spent in interplanetary doldrums, waiting to arrive at the destination. |
|
As an important side benefit, interplanetary trajectories that begin at Lagrangian points require very little fuel to reach other Lagrangian points or even other planets. |
|
Fragments of asteroids and comets pervade interplanetary space. |
|
|
One of the emerging branches of research focused on the galactic and solar origins of cosmic rays and the modulation of their flux by the interplanetary magnetic field. |
|
The payload-to-fuel ratio likewise comes into play during interplanetary flights, given the immense distances a spacecraft traveling within the solar system must cover. |
|
For although they travel at the speed of light, critical messages controlling the on-board systems of these interplanetary probes can take over 90 minutes to travel from Earth to the spacecraft and back. |
|
The spacecraft had hopped aboard the interplanetary superhighway, a network of tubes criss-crossing through the solar system. |
|
The Workshop was to conduct basic study activities of the heliosphere, interplanetary space and the Earth's atmosphere and magnetosphere and raise awareness of space science in developing countries. |

|
While focused on activities related to the Stardust mission, this work also looks at cratering in foils and metals for a wide range of speeds and sizes typical of impacts in LEO and interplanetary space. |
|
The packaging, however, is quite different and the front cover shows an illustration by Mark Wilkinson depicting Eddie as some sort of interplanetary ambassador giving a press conference. |
|
The interaction between solar wind and the magnetosphere occurs at the border between the closed lines of terrestrial magnetic field and those which are open on the interplanetary medium. |

Interactions of the Earth's electromagnetic field with the interplanetary disturbances are especially strong in the polar areas and in the surrounding 'auroral zones', where most auroras can be seen. |
|
It is distinct from the concept of weather within a planetary atmosphere and generally deals with the interactions of ambient radiation and matter within interplanetary, and occasionally interstellar, space. |
