India’s lunar lander orbiter craft ‘Chandrayaan-2’ was put in the way of Moon, some 3.84 lakh km away, in the week hours of Wed, ISRO said.
Its orbit was built for the 6th and last-time on the earth side from ISRO Telemetry Tracking and Command Network in Bengaluru at 2.21 AM
Post-operation, the satellite is usually performing, ISRO told.
“Today (August 14, 2019) after the trans-Lunar Insertion (TLI) procedure performance, #Chandrayaan2 will leave from Earth’s orbit and travel towards the Moon (sic),” the ISRO tweeted.
It will move for the next 7-days and get close to Moon on Aug-20 when its orbit is changed regularly to make it revolve around Moon. The spacecraft takes lander Vikram and rover Pragyan on it. The mission is the country’s 1st lunar soft-landing attempt. The marina itself is slated for September 7.
The Bengaluru headquartered space agency said it has carried out a procedure called ‘Trans Lunar Insertion’following which the spacecraft has successfully joined the Lunar Transfer Trajectory.
“During the last orbit raising of the spacecraft around the Earth, the liquid engine was shot for about 1203 sec. With this, Chandrayaan-2 started the Lunar Transfer Trajectory,” the space agency said.
Earlier, the spacecraft’s orbit was progressively increased 5- times between July 23 and August 6.
The health of the spacecraft is “continuously controlled” from the Mission Operations Complex (MOX) at ISRO Telemetry Tracking and Command Network (ISTRAC) with assistance from Indian Deep Space Network wires at Byalalu, near Bengaluru, it told.
“Since its launch on July-22 all systems onboard Chandrayaan-2 rocket is performing normally,” the ISRO said.
The spacecraft will approach the Moon on Aug- 20, and then the spacecraft’s liquid engine will be shot again to insert it into lunar orbit, the ISRO told.
“Following this, there will be 4-orbit plans to make the spacecraft enter its final orbit, flying over the lunar poles at a range of about 100 km from the moon’s surface,” it answered.
In a giant leap for the country’s driving low-cost space programme, ISRO’s most potent 3-stage rocket GSLV MkIII M1 had launched the spacecraft into the orbit of the Earth on July-22 from the spaceport of Sriharikota, AP.
According to ISRO, after 13 days of Moon bound orbit phase, the lander ‘Vikram’ carrying rover ‘Pragyan’ will leave and after another few days of orbiting will soft-land on Sep-7 in the South Pole area of the Moon, where no nation has performed so far, according to the ISRO.
If successful, the mission will move India the 4th country after Russia, the U.S. and China to pick off a soft landing on the Moon.
The orbiter carries eight scientific payloads for planning the lunar cover and study the exosphere (outer atmosphere) of the Moon while the lander takes three scientific payloads to handle exterior and subsurface science operations.
The rover carries 2-payloads to enhance the perception of the lunar surface. Passive research from NASA will also be taken on board Chandrayaan-2, ISRO has announced.
Following the arrival, the rover will roll out from the lander and carry out measures on the lunar surface for 1- lunar day, which is equivalent to 14 – earth days. The mission time of the lander is also one lunar day, while the orbiter will maintain its mission for a year.
According to the ISRO, the mission goal of Chandrayaan-II is to improve and show the critical technologies for end-to-end lunar mission capacity, including soft-landing and moving on the lunar surface.
It also aims to further expand the information about the Moon through a detailed study of its topography, mineralogy, surface element structure, thermo-physical properties and environment, leading to a better knowledge of the origin and development of the Moon, the space agency had spoken.
