MAST EUVE All Sky Survey (376 words) |
 | The completed survey data set covers approximately 97% of the sky with exposures ranging from a few hundred seconds at the ecliptic to 20 kiloseconds at the poles. |
| The scanning telescopes are swept across the sky by the slowly revolving spacecraft, while the deep survey telescope is pointed down the Earth's shadow. |
| Consequently, scientists configured the mission so that the deep survey telescope always pointed away from the Sun and only took measurements while viewing down Earth's shadow - the night portion of the orbit when the Earth blocks the Sun and shields the spacecraft from sunlight. |
