ISRO to put Chandrayaan-2 into lunar orbit on Tuesday

The moon-bound Chandrayaan-2 spacecraft is scheduled to undergo a crucial orbit manoeuvre around 9.30 a.m. on Tuesday morning as it approaches its destination.

Chandryaan-2 is on its way to the moon and is all set to land near the south pole of the moon on September 7 said Indian Space Research Organization (ISRO).

This is an important event for the Chandrayaan-2 mission, as it marks the beginning of the penultimate phase of the journey.

We will provide a critical velocity to Chandrayaan-2: reduce its velocity and change its direction so that it enters Moon's orbit. In doing this, ISRO has also taken support from the Indian Deep Space Network (IDSN) antennas at Byalalu, near Bengaluru.

US military tests ground-based cruise missile
A ground-launched cruise missile was successfully fired in a test, the Defense Department announced on Monday. The ground-launched version of the Tomahawk was removed from service after the INF was ratified.

Eventually, Vikram lander will separate from the orbiter on September 2. "If the couple have to meet, then the precision and accuracy is of utmost importance". The lift-off was successful in its second attempt, a week after it was aborted just under an hour from its launch due to a technical glitch.

After shooting off into space, the spacecraft's orbit was "progressively increased five times" between July 23 and August 6. It was then flung towards the Moon, at a distance of 3.84 lakh kilometres away. "Thereafter, two more manoeuvres will be performed on Vikram before the power descent starts to make the lander make a soft-landing on Moon between 1.30am and 2.30am on September 7", Sivan said.

Vikram and Pragyan are expected to be in action for the next fortnight (one lunar day), as the moon faces the sun and powers their batteries as they conduct a slew of experiments, ranging from understanding the moon's landscape to sniffing around for water to analysing the moon's ionosphere.
