LOS ANGELES, Oct. 19 (Xinhuanet)-- The unique
capabilities of the Hubble Space Telescope would help locate oxygen-bearing
minerals on the moon critical for a future manned exploration, US space agency
NASA said on Wednesday.
The moon does not have a breathable
atmosphere, so oxygen-bearing minerals such as ilmenite (titanium and iron
oxide)may be a potential source of oxygen for astronauts to breath or to power
rockets, scientists explained.
NASA's Hubble team said the resolution and
sensitivity to ultraviolet light of the telescope have allowed them to search
for important oxygen-bearing minerals on the moon.
The images acquired in new observations provide
scientists witha new tool to study mineral variations within the lunar crust.
As NASA plans future expeditions to the moon, such
data, in combination with other measurements, will help ensure the most valuable
sites are targeted for robotic and human missions, scientists said .
"These observations of the moon have been a
challenging and highly successful technological achievement," said Jennifer
Wiseman, program scientist for the Hubble. "The images will inform both
scientific studies of lunar geology and future decisions on further lunar
exploration."
Hubble's Advanced Camera for Surveys snapped
ultraviolet and visible light images of known geologically diverse areas on the
side of the moon nearest Earth. These included the Aristarchus impact crater and
the adjacent Schroter's Valley. Hubble also photographed the Apollo 15 and 17
landing sites, where astronauts collected rock and soil samples in 1971 and
1972.
Scientists are comparing the properties of the rock
and soil samples from the Apollo sites with the new Hubble images, and the
Aristarchus region, which neither humans nor robotic spacecraft have visited.
The Hubble observations of Aristarchus crater and
Schroter's Valley will help refine researchers' understanding of the diverse,
interesting materials in the region and to unravel their full resource
potential, scientists said.
"Our initial findings support the potential existence
of some unique varieties of oxygen-rich glassy soils in both the Aristarchus and
Apollo 17 regions. They could be well-suited for visits by robots and human
explorers in efforts to learn how to live off the land on the moon," said Jim
Garvin, chief scientist at NASA's Goddard Space Flight Center.
Scientists are confident that these new observations
will help better inform exploration decisions, Garvin noted. Enditem
