Namaku Terbang Ke Bulan

http://lro.gsfc.nasa.gov/images/mainliftoff-s.jpg

Setelah tertunda berbulan-bulan dari rencana awal peluncuran bulan November 2008, pada tanggal 18 Juni 2009 roket Atlas V diluncurkan dengan membawa Lunar Reconnaissance Orbiter (LRO) dan Lunar Crater Observation and Sensing Spacecraft (LCROSS) ke Bulan. LRO dan LCROSS ini terbangkan ke Bulan untuk untuk mengumpulkan informasi guna mendukung misi berawak manusia ke Bulan di masa mendatang.

Lunar Reconnaissance Orbiter (LRO) milik NASA ini dijadwalkan mencapai orbit bulan pada tanggal 23 Juni 2009 5:43 EDT. LRO mengangkasa sejauh 360.000 kilometer untuk mencapai orbit Bulan.

LRO akan mengorbit mengelilingi Bulan dan mengumpulkan informasi lanjutan mengenai permukaan bulan yang cocok untuk digunakan landasan pesawat atau astronot di masa mendatang. Satelit ini juga mengumpulkan informasi mengenai lingkungan di Bulan. LRO akan mengorbit 31 mil di atas permukaan Bulan selama satu tahun. LRO mempunyai tujuh alat yang bisa membuat peta Bulan dalam bentuk 3D dengan resolusi yang tinggi. Alat-alat belum dinyalakan pada saat ini, rencananya baru pada awal bulan depan akan digunakan untuk merekam gambar.

Sedangkan LCROSS akan diarahkan ke bagian kawah di Bulan yang selalu tertutup bayangan, LCROSS akan meneliti keberadaan air di sekitar kutub Bulan.

    NASA Lunar Mission Successfully Enters Moon Orbit

    GREENBELT, Md. — After a four and a half day journey from the Earth, the Lunar Reconnaissance Orbiter, or LRO, has successfully entered orbit around the moon. Engineers at NASA’s Goddard Space Flight Center in Greenbelt, Md., confirmed the spacecraft’s lunar orbit insertion at 6:27 a.m. EDT Tuesday.

    During transit to the moon, engineers performed a mid-course correction to get the spacecraft in the proper position to reach its lunar destination. Since the moon is always moving, the spacecraft shot for a target point ahead of the moon. When close to the moon, LRO used its rocket motor to slow down until the gravity of the moon caught the spacecraft in lunar orbit.

    “Lunar orbit insertion is a crucial milestone for the mission,” said Cathy Peddie, LRO deputy project manager at Goddard. “The LRO mission cannot begin until the moon captures us. Once we enter the moon’s orbit, we can begin to buildup the dataset needed to understand in greater detail the lunar topography, features and resources. We are so proud to be a part of this exciting mission and NASA’s planned return to the moon.”

    A series of four engine burns over the next four days will put the satellite into its commissioning phase orbit. During the commissioning phase each of its seven instruments is checked out and brought online. The commissioning phase will end approximately 60 days after launch, when LRO will use its engines to transition to its primary mission orbit.

    For its primary mission, LRO will orbit above the moon at about 31 miles, or 50 kilometers, for one year. The spacecraft’s instruments will help scientists compile high resolution, three-dimensional maps of the lunar surface and also survey it at many spectral wavelengths.

    The satellite will explore the moon’s deepest craters, examining permanently sunlit and shadowed regions, and provide understanding of the effects of lunar radiation on humans. LRO will return more data about the moon than any previous mission.

    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:

    http://www.nasa.gov/lro

    “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.

    Good point, though sometimes it’s hard to arrive to definite conclusions

    What’s up to all, how is all, I think every one is getting more from this website, and your views are pleasant for new people.
