서명덕 기자지난 6월 18일 플로리다 Cape Canaveral Air Force Station을 출발한 NASA의 궤도탐사선(Lunar Reconnaissance Orbiter)가 지난 6월 30일 처음으로 보내 준 달 사진이 공개됐습니다. 미국은 약 40년 만에 달 탐사를 재개한 셈입니다.

LRO 이놈은 저해상도 와이드 앵글 카메라와 고해상도 카메라 두 종류를 탑재하고 있는데, 낮과 밤을 동시에 커버하기 위해서라고 합니다. 최대 19마일 상공까지 접근 가능하며, 일반적으로는 31마일 위에서 촬영을 할 예정입니다. LRO의 최종 목적 중 하나는 향후 달 착륙이 가능한 공간을 탐색하는 것입니다.
또한 아시다시피 이번에는 애틀라스 5 로켓에 실린 것은 LRO 뿐만이 아니라 크레이터 충돌체 및 위성이 결합된 LCROSS 도 있습니다. LCROSS는 달을 지나 지구의 타원궤도에 진입, 110일간 지구를 두 차례 돌고 난 뒤 지구의 중력을 이용해 오는 10월 초 달의 남극 지역에 두 차례 충돌할 예정입니다.

RELEASE : 09-152 NASA's LRO Spacecraft Sends First Lunar Images to Earth GREENBELT, Md. -- 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 of a region a few kilometers east of Hell E crater in the lunar highlands south of Mare Nubium.
As the moon rotates beneath LRO, LROC gradually will build up photographic maps of the lunar surface. To view these first calibration images, visit:
"Our first images were taken along the moon's terminator -- the dividing line between day and night -- making us initially unsure of how they would turn out," said LROC Principal Investigator Mark Robinson of Arizona State University in Tempe. "Because of the deep shadowing, subtle topography is exaggerated, suggesting a craggy and inhospitable surface. In reality, the area is similar to the region where the Apollo 16 astronauts safely explored in 1972. While these are magnificent in their own right, the main message is that LROC is nearly ready to begin its mission."
LRO will help NASA identify safe landing sites for future explorers, locate potential resources, describe the moon's radiation environment and demonstrate new technologies.
The satellite also has started to activate its six other instruments. The Lunar Exploration Neutron Detector will look for regions with enriched hydrogen that potentially could have water ice deposits. The Cosmic Ray Telescope for the Effects of Radiation is designed to measure the moon's radiation environment. Both were activated on June 19 and are functioning normally.
Instruments expected to be activated during the next week and calibrated are the Lunar Orbiter Laser Altimeter, designed to build 3-D topographic maps of the moon's landscape; the Diviner Lunar Radiometer Experiment, which will make temperature maps of the lunar surface; and the Miniature Radio Frequency, or Mini-RF, an experimental radar and radio transmitter that will search for subsurface ice and create detailed images of permanently-shaded craters.
The final instrument, the Lyman Alpha Mapping Project, will be activated after the other instruments have completed their calibrations, allowing more time for residual contaminants from the manufacture and launch of LRO to escape into the vacuum of space. This instrument is an ultraviolet-light imager that will use starlight to search for surface ice. It will take pictures of the permanently-shaded areas in deep craters at the lunar poles.
"Accomplishing these significant milestones moves us closer to our goals of preparing for safe human return to the moon, mapping the moon in unprecedented detail, and searching for resources," said LRO Project Scientist Richard Vondrak of NASA's Goddard Space Flight Center in Greenbelt, Md.
While its instruments are being activated and tested, the spacecraft is in a special elliptical commissioning orbit around the moon. The orbit takes less fuel to maintain than the mission's primary orbit. The commissioning orbit's closest point to the lunar surface is about 19 miles over the moon's south pole, and its farthest point is approximately 124 miles over the lunar north pole.
After the spacecraft and instruments have completed their initial calibrations, the spacecraft will be directed into its primary mission orbit in August, a nearly-circular orbit about 31 miles above the lunar surface.
Goddard built and manages LRO, a NASA mission with international participation from the Institute for Space Research in Moscow. Russia provides the neutron detector aboard the spacecraft.
