NASA’s Lunar Reconnaissance Orbiter, or LRO, has transmitted its first images since reaching lunar orbit June 23. The spacecraft has two cameras — a low resolution Wide Angle Camera and a high resolution Narrow Angle Camera. Collectively known as the Lunar Reconnaissance Orbiter Camera, or LROC, they were activated June 30. The cameras are working well and have returned images … Read the rest of this article
The Lunar Crater Observation and Sensing Satellite, or LCROSS, successfully completed its most significant early mission milestone Tuesday with a lunar swingby and calibration of its science instruments. The satellite will search for water ice in a permanently shadowed crater at the moon’s south pole.
With the assist of the moon’s gravity, LCROSS and its attached Centaur booster rocket successfully … Read the rest of this article
NASA’s Lunar Reconnaissance Orbiter launched at 5:32 p.m. EDT Thursday aboard an Atlas V rocket from Cape Canaveral Air Force Station in Florida. The satellite will relay more information about the lunar environment than any other previous mission to the moon.
The orbiter, known as LRO, separated from the Atlas V rocket carrying it and a companion mission, the Lunar … Read the rest of this article
Scientists using NASA’s RHESSI spacecraft have measured the roundness of the sun with unprecedented precision, and they find that it is not a perfect sphere. During years of high solar activity the sun develops a thin “cantaloupe skin” that significantly increases its apparent oblateness. Their results appear the Oct. 2nd edition of Science Express.
“The sun is the biggest … Read the rest of this article
WASHINGTON — A NASA spacecraft will conduct the second of three flybys of Mercury on Oct. 6 to photograph most of its remaining unseen surface and collect science data.
The MErcury Surface, Space ENvironment, GEochemistry, and Ranging, or MESSENGER, spacecraft will pass 125 miles above the planet’s cratered surface, taking more than 1200 pictures. The flyby also will provide a … Read the rest of this article
