The Indian space agency on Tuesday successfully raised Chandrayaan-2's orbit for fifth time at 3:04pm. According to Indian Space Research Organisation (ISRO), the orbit of Chandrayaan-2 was raised to an orbit of 276x142,975km by firing the spacecraft's onboard motors for 1,041 seconds. All spacecraft parameters were normal. The next manoeuvre is Trans Lunar Insertion (TLI), which is scheduled for August 14, 2019, between 3-4am. On July 22, the Chandrayaan-2 was injected into an elliptical orbit of 170x45,475km by India's heavy lift rocket Geosynchronous Satellite Launch Vehicle-Mark III (GSLV Mk III) in a textbook style. The spacecraft comprises three segments - the Orbiter (weighing 2,379kg, eight payloads), the lander 'Vikram' (1,471kg, four payloads) and rover 'Pragyan' (27kg, two payloads). The Indian space agency said the major activities include Earth-bound manoeuvres, the trans-lunar insertion, lunar-bound manoeuvres, Vikram's separation from Chandrayaan-2 and touch down on the Moon's South Pole. The ISRO said the trans-lunar insertion of Chandrayaan-2, which will send it to the moon, is scheduled on August 14. After that, the Chandrayaan-2 is scheduled to reach the Moon by August 20 and the lander Vikram will land on the Earth's sole satellite on September 7. Source: IANS News
The Moon and Mercury may have thick ice deposits Greenbelt MD (SPX) Aug 05, 2019 Earth's Moon and Mercury, the closest planet to the Sun, may contain significantly more water ice than previously thought, according to a new analysis of data from NASA's LRO and MESSENGER spacecraft. The potential ice deposits are found in craters near the poles of both worlds. On the Moon, "We found shallow craters tend to be located in areas where surface ice was previously detected near the south pole of the Moon, and inferred this shallowing is most likely due to the presence of buried thick ... read more
