The picture was made by rolling the entire spacecraft, adjusting its rotation rate to match the ground speed under the camera. |
|
Last November, Russia launched the Phobos-Grunt spacecraft to explore Phobos, one of Mars's two moons. |
|
The spacecraft also made the first detection of magnesium in Mercury's thin atmosphere, known as an exosphere. |
|
Unlike most spacecraft, which use thrusters to adjust their orbits, it has a highly efficient propulsion system called an ion engine. |
|
So-called killer electrons, which are charged particles revved up to energies greater than 1 million electronvolts, punch through the skin of spacecraft. |
|
Events this year include commanding the spacecraft out of hibernation mode, a complete system health checkout, and an Earth flyby for a gravity assist to Comet Boethin. |
|
The Van Allen belts can pose a severe danger to satellites and spacecraft, with hazards ranging from minor anomalies to the complete failure of critical satellites. |
|
A 10-minute drive away is the Cosmosphere, a brilliant interactive space museum with one of the largest collections of artefacts and spacecraft in the world. |
|
Chapter 7 reviews the many important and critical contributions of Ary Stemfeld to spacecraft trajectories and maneuvers, a major area of modern cosmonautics. |
|
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. |
|
By 1960, NASA had sketched the outline for a decadelong effort toward unmanned and then manned lunar explorations, as well as sending spacecraft to Venus and Mars. |
|
The IMBU shall be implemented as a flexible system that can be easily reconfigured for testing the ground station to spacecraft communications interfacing at different levels. |
|
A recent Nasa paper suggested that the spacecraft was still in a transition zone between the sun's sphere of influence and the rest of the Milky Way. |
|
The primary mission of all human space flight is getting the crew back alive, and so we burden the spacecraft with life-support equipment and we limit where it can go. |
|
By working together, our team will continue to maintain the world's finest manned spacecraft and support satellite and space defense systems with dedication and pride. |
