ISRO releases pictures of impact craters on Moon

Chennai: Indian space agency has released fresh set of pictures of impact craters on moon surface taken by its Chandrayaan-2 Orbiter.The Indian Space Research Organisation (ISRO) on Tuesday releasing a picture on its Twitter handle said the images were taken by the Dual Frequency-Synthetic Aperture Radar (DF-SAR) on its Chandrayaan-2 Orbiter. According to ISRO, the Moon has been continuously bombarded by meteorites, asteroids and comets since its formation. This has resulted in the formation of innumerable impact craters that form the most distinct geographic features on its surface. Impact craters are approximately circular depressions on the surface of the moon, ranging…

Bhubaneswar: Indian Space Research Organisation (ISRO) chairman K. Sivan on Saturday said Chandrayaan-2 mission has achieved 98 per cent of its objectives, while they are yet to establish any communication with lander 'Vikram'. "We could not have established any communication with the lander yet. The project was developed in two parts - science and technology demonstration. We achieved total success in science objective while in technology demonstration, the success percentage was almost full. That's why the project can be termed as 98 per cent successful," Sivan told media persons. The ISRO chairman is in the city to attend the 8th Convocation…

Search for Vikram on: NASA scientists analyse lunar images from orbiter

New York: Scientists are analysing the images taken under harsh light conditions by the NASA Lunar Reconnaissance Orbiter (LRO) Camera of the area where the Vikram moon lander is likely to have touched down on the moon and it may be a while before they can locate it, project experts told IANS. LRO project scientist at NASA's Goddard Space Flight Center, Noah Petro, said on Wednesday that they were now analysing the images taken on Tuesday "and we will make a statement at some point when we can identify the lander." But he added, "It is important to remember that the…

"#VikramLander has been located by the orbiter of #Chandrayaan2, but no communication with it yet," the Indian Space Research Organisation (ISRO) tweeted. "All possible efforts are being made to establish communication with lander," ISRO said. The ISRO did not, however, say in what condition the lander is on the lunar surface. The space agency continues to remain silent as to proximate cause for the moon lander tumbling and deviating from its original flight path on September 7 early morning.

‘Reducing Chandrayaan-2 Orbiter’s orbit may be dangerous’

Chennai: Reducing the orbit of Chandrayaan-2 Orbiter to pick up any weak signals or to take a closer look the moon lander Vikram that had crash-landed on the lunar surface is a dangerous move, contend space scientists.According to sources, the Indian Space Research Organisation (ISRO) is looking at reducing Chandrayaan-2 Orbiter's orbit from 100 km to 50 km above the lunar surface."Reducing the orbit of the Orbiter is a dangerous idea," a former space agency official, speaking on condition of anonymity, told IANS. "What is ISRO going to gain by this move is not known. Even if the Orbiter is able…
