UV-Resistant Micro-Organisms Discovered In the Stratosphere
junglee_iitk writes "Three new species of bacteria, which are not found on earth and highly resistant to ultraviolet radiation, have been discovered in the upper stratosphere by some Indian scientists. These bacteria, which do not match any species on earth, were found in samples collected through a balloon sent up to the stratosphere in April 2005. The payload consisted of a cryosampler containing 16 evacuated and sterilised stainless steel probes. Throughout the flight, the probes remained immersed in the liquid neon to create a 'cryopump effect.' These cylinders after collecting air samples from different heights ranging from 20 to 41 km were parachuted down and safely retrieved, it said." Here's the Indian Space Research Organisation's press release on the discovery. Adds an anonymous reader: "This paper in International Journal of Astrobiology [PDF] speculates how microorganisms reach the stratosphere." -
Chandrayaan M3 Instrument Confirms Iron-Bearing Minerals On the Moon
William Robinson writes with news that the Moon Mineralogy Mapper (M3), an instrument developed by NASA and sent aboard India's Chandrayaan-1, has confirmed the presence of iron-bearing minerals on the moon. This marks the beginning of an extensive examination of the composition of the lunar surface. "Isro officials said M3 would help in characterising and mapping lunar minerals to ultimately understand the moon's early geological evolution. 'The compositional map that will come out of M3 will have fantastic data on geological formation of the moon,' the official said. Researchers said the relative abundance of magnesium and iron in lunar rocks could help confirm whether the moon was covered by a molten, magma ocean early on in its history. Iron and magnesium will also indicate melting of the moon, if it happened and how it formed later. This metallic element has been found in lunar meteorites, but scientists know little about its distribution in the lunar crust." -
Chandrayaan Enters Lunar Orbit
William Robinson writes "After an 18-day journey, Chandrayaan-1, the moon mission of India, has entered Lunar orbit. The maneuver was described as crucial and critical by scientists, who pointed out that at least 30 per cent of similar moon missions had failed at this juncture, resulting in spacecraft lost to outer space. The lunar orbit insertion placed Chandrayaan-1 in an elliptical orbit with its nearest point 400 to 500 kilometers away from the moon, and the farthest, 7,500 kilometers. By November 15, the spacecraft is expected to be orbiting the moon at a distance of 100 kilometers and sending back data and images (the camera was tested with shots looking back at Earth). The Chandrayaan-1 is also scheduled to send a probe to the moon's surface." -
India's Successful Commercial Satellite Launch
An anonymous reader writes "Yesterday India successfully launched an Italian astronomical satellite. A BBC article (view video clip) notes that the launch grants India membership in the exclusive group of nations that can sustain commercial satellite launches. India's launch vehicle has less overall capacity than the competition — up to 1,500 kg to orbit — but the country plans to sweep the low end of the market by offering the lowest cost per launched kilogram for smaller payloads." -
India Brings Back Orbiting Satellite to Earth
bharatm writes "In a pathbreaking event heralding its arrival as a space power with capability to recover an orbiting satellite, India today successfully brought back a spacecraft to earth, giving a new impetus to the proposed manned mission to space in the next decade." -
India Plans Moon Mission In 2005
ghoul writes: "I just came across this article in which the Indian Space Research Organization (ISRO) has announced plans for a moon mission. Considering that till now India has only launched geo-synchronous satellites, that's a big leap. But ISRO scientists claim by using a lightweight orbital vehicle they can use their existing PSLV (which launches 1-tonne missions into polar orbit) to send an orbiter to the moon. The full article is available at India Today ." (No, not a manned mission, at least not yet.)
