Found Its Lost Vikram Lander The Chandrayaan-2’s Vikram module has been placed on the lunar surface, and it need have been a hard-landing, ISRO Chairman K Sivan announced on Sunday, in an allegation that the planned soft-landing wasn’t successful
“Yes, Found Its Lost Vikram Lander on Lunar Surface. It must have been a hard landing”, Sivan was extracted as saying by news agency PTI. The image of the lander-rover ‘Pragyan’ is housed inside it was taken by the onboard camera of Chandrayaan-2 orbiter, which is robust, safe and operating normally in the planned orbit around the Moon.
The orbiter camera is the most potent resolution camera (0.3m) in any lunar mission so far and shall render high-resolution images.
which will be immensely helpful to the global scientific community, the Bengaluru-headquartered space agency must say earlier.
India’s bold purpose to soft-land on the Moon experienced a setback with the ‘Vikram’ module missing communication with ground stations,
just 2.1 km from the lunar facade during its final fall in the early hours of Saturday.
Recognized as the “most complex” stage of the country’s 2nd expedition to the Moon, the lander was on a powered family for a soft landing when it lost connection. The data is being investigated, the ISRO had announced soon after.
Asked if the lander was ‘damaged’ throughout the ‘hard landing”, Sivan said: “That we do not know”. But some space specialists said Vikram sustaining damage in the hard-landing could not be ruled out. “It may not have landed at a wanted level of velocity. It may not have landed on its 4-legs. Impact shock may become generated damage to the lander”, according to a space official.
“When the method does not work well, it (the lander) will run and hit the Moon. There is no uncertainty in that”, another specialist space expert said. “Unless all the things are paid…compensating gravity, it (the lander) will not come down smoothly and reach the surface. That’s the crucial part of the whole manoeuvre”, he said.
Sivan had announced on Saturday that the space agency would try to build the link with the lander for 14 days and repeated on Sunday.
after it was found on the lunar surface by Chandrayaan-2’s onboard cameras that those forces would proceed.
He had said that Vikram lander’s extraction was as planned and typical performance was followed up to an elevation of 2.1 km,
but subsequently, information from the lander to ground-stations was lost.
A senior ISRO official told Found Its Lost Vikram Lander,time was running out, and the chance of re-establishing communication looks “less and less probable”.
“Progressively…as time passes by…it’s challenging (establish link)”, the official said but calculated that with the “right introduction” it can still generate power and recharge batteries with solar panels. “But it looks less & less probable, progressively”, the official said on state of anonymity.
According to ISRO, 90 to 95% of the Chandrayaan-2 mission objectives have been accomplished, and it will continue to add to lunar science, notwithstanding the loss of communication with the lander. The space agency also said the exact launch & mission management had secured a long life of almost 7-years, instead of the planned 1year for the orbiter.
Meanwhile, Sivan said PM Narendra Modis address and the overflow of support and kind words for ISRO.
after the Chandrayaan-2 Vikram, unsuccessful bid to touchdown on Lunar surface has boosted the morale of its scientists and engineers.
“We are delighted (the PMs address as well as nation rallying behind ISRO). It has raised the spirit of our people”, Sivan told PTI. “We are so impressed, former ISRO Chairman K Kasturirangan said. “The nation has given a good, positive response. PM was impossible yesterday”, as he praised Modi for inspiring, supporting and encouraging Sivan and ISRO team and fully lining them.
“The way he (PM) moved it…so passionate…so emotional and seldom loaded with meanings and positive-responses. I think we could not have assumed anything better. Excellent”, he told PTI.
“We are thankful for the nation and PM”, said another former ISRO Chairman A S Kiran Kumar,
who saw that there are hundreds and thousands of changes that were probable for the soft landing mission, as he underlined the complexities of the task.
“We appreciate that the nation and people were able to take note of this and proceed to give their support. So, it’s genuine. We are thankful for the entire country”, he said.
The successful touchdown would have made India the fourth country after erstwhile USSR,
the US, China to achieve a soft landing the Moon, the first to launch a mission unexplored -south pole of the Moon.
The orbiter payloads will send remote-sensing observations from a 100 km orbit.
Chandrayaan-2, a follow-on mission to the Chandrayaan1 mission offered more than a decade ago, includes an orbiter, lander Vikram & rover Pragyan.
The orbiter takes eight scientific payloads for planning the lunar-surface and studies the exosphere (without air) of the Moon. ISRO on Sep-2 successfully sent out the division of lander Vikram with rover Pragyan housed inside from the Chandrayaan2 orbiter.
The Vikram module, which was thought to carry out several tests on the lunar soil,
had made the rough braking phase as planned and entered the stage of exceptional braking at an elevation of 2.1 km when it lost communication.
ISRO officials said on Sunday Found Its Lost Vikram Lander that data possible till the lander lost communication
with the ground-stations was being analyzed to find out what exactly went wrong but declined to specify a timeline for doing the exercise.
‘Vikram’, called after Dr Vikram A Sarabhai, the father of the Indian-space details,
was created to execute a soft arriving on the lunar surface and to function for one lunar day, which is equal to about 14 earth days.
The rover was to operate lander explore lunar terrain, a few hours after the planned soft-landing. Chandrayaan-2 is a Rs 978 crore uncrewed moon mission (satellite cost Rs-603 crore, GSLV MK III cost Rs-375 crore). India’s Geosynchronous Satellite-Launch Vehicle, GSLV MkIII-M1 successfully launched the 3,840-kg Chandrayaan-2 spacecraft on July-22.
