All about Isro’s Chandrayaan 2 mission and landing of Vikram lander

If you are interested in scientific research and engineering development then here you go. In this blog, you get all about Isro’s Chandrayaan 2 mission and landing of Vikram lander.

What is  Isro’s Chandrayaan 2 mission?

Chandrayaan, which signifies “moon vehicle” in Sanskrit. Chandrayaan 2 is on a unique mission. Utilizing almost a time of scientific research and engineering development, India’s second lunar undertaking will reveal insight into a totally unexplored area of the Moon — it’s South Polar region. The Chandrayaan 2 mission intends to deliver a rover to an elevated plane near the uncharted lunar South Pole on 6 or 7 September. This mission will help us to better understand the origin and evolution of the Moon by directing point by conducting detailed topographical studies, far-reaching mineralogical analyses, and a large group of different trials on the lunar surface. While there, we will likewise investigate discoveries made by Chandrayaan 1, for example, the presence of water molecules on the Moon and potentially new sources of abundant energy and new rock types with unique chemical composition.

Isro’s Chandrayaan 2 mission, this aim to:

  • Expand India’s footprint in space
  • Inspire a future generation of scientists, engineers, and explorers
  • Surpass international aspirations

When was the launch scheduled of Chandrayaan2?


Chandrayaan 2 launch planned on 15th July 2019 at 2:51hrs was canceled because of a technical snag noticed at around one hour before launch. The launch was rescheduled on July 22, 2019, at 14:43 hrs IST. It was from Satish Dhawan Space Center at Sriharikota onboard GSLV Mk-III. It will be injected into an earth parking 170 x 39120 km orbit. A series of moves will be done to raise its orbit and put Chandrayaan 2 on Lunar Transfer Trajectory. On entering Moon’s sphere of influence, on-board engines will slow down the spacecraft for Lunar Capture. The Orbit of Chandrayaan 2 around the moon will be circularized to 100 x 100 km orbit through a series of orbital maneuvers.

Do you know the Landing process of Vikram Lander and Orbiter?

What is the landing process of Vikram Lander and Orbiter


On the day of landing, the lander will isolate from the Orbiter and afterward perform a series of complex moves including rough breaking and fine breaking. Imaging of the landing site area before landing will be done for discovering safe and hazard-free zones. The lander-Vikram will at last land near the South Pole of the moon on Sep 7, 2019. Consequently, Rover will roll out and carry out experiments on Lunar surface for a time of 1 Lunar day which is equivalent to 14 Earth days. The orbiter will continue its mission for a duration of one year.

Chandrayaan 2 Science experiments

Chandrayaan 2 has a few science payloads to extend the lunar scientific knowledge through detailed investigation of topography, seismography, mineral identification and distribution, surface chemical composition, thermo-physical qualities of topsoil and composition of the shaky lunar atmosphere, leading to a new understanding of the origin and evolution of the Moon.

The Orbiter payloads will lead remote-sensing observations from a 100 km orbit while the Lander and Rover payloads will perform in-situ measurements close to the landing site.

Let’s get a better understanding of Lunar creation

For an understanding of the Lunar creation, it is intended to identify the elements and mapping its distribution on the lunar surface both at worldwide and In-situ level. In addition, detailed 3-dimensional mapping of the lunar regolith will be finished. Estimations on the near-surface plasma environment and electron density in the Lunar ionosphere will be examined. Thermo-physical property of the lunar surface and seismic activities will likewise be estimated. Water particle dispersion will be studied using infrared spectroscopy, synthetic aperture radiometry, and polarimetry as well as mass spectroscopy strategies.

What happened to Chandrayaan 2 landing? And  how Vikram lander goes silent seconds before landing

The Indian Space Research Organization lost contact with the Chandrayaan 2 lander Vikram only minutes before it was to land on close to the south pole of the Moon. The Chandrayaan 2 mission, however, is far from being a failure.

The Indian Space Research Organization’s ’15 minutes of terror’ was going to reach an epic end. Or, so it appeared. The setting was Isro’s Mission Operations Complex in Bengaluru that is tracking the progress of Chandrayaan 2, India’s second mission to the Moon. Furthermore, the event was the landing of Vikram and Pragyaan, the Chandrayaan 2 lander and rover.

The landing was to make India the only country in the world to land a rover close to the south pole of the Moon.

When was the landing started?

The landing started just minutes before 1:40 am on Saturday. And for the few couples of minutes, everything went as per the plan. Jubilant Isro scientists at the Mission Operations Complex cheered and clapped as Vikram passed the different phases of descent on to the lunar surface.

What happened to Chandrayaan 2 landing?

All of a sudden, around 12 minutes after Vikram started its descent, things went wrong. Those outsides of Isro’s control center did not know what went wrong. However, the pin-drop silence at the control center and the stress crawling upon the faces of the Isro scientists there gave a suspicion of something turning out wrong.

The next couple of minutes felt like hours as a restless India waited for news from Isro. At that point, Isro chief K Sivan was seen going to the control center’s viewing gallery, where Prime Minister Narendra Modi was sitting, watching the Chandrayaan 2 landing.

Sivan and a couple of different scientists were seen briefing the prime minister. The body language – the prime minister making an ‘okay then’ gesture and scientists praising the Isro chief on his back – did not do a lot to raise hopes.

A few minutes later, K Sivan took to a microphone at the Isro’s control center and confirmed the worst: Isro had lost contact with the Vikram lander. Sivan made the announcement by saying that up until contact was lost with the Chandrayaan 2 lander, it had performed precisely as it should.

Contact with the Vikram lander was lost when it was just 2.1 kilometers above the lunar surface and Isro was examining the information from the descent, Sivan said. As of the last updating this report, that is all we think about what happened to the Vikram lander.

Chandrayaan 2 lander goes silent. What next?

After losing contact with the Chandrayaan 2 lander, the Indian Space Research Organization went into a group. The space organization canceled a scheduled press conference and asked media people to leave its control center as it got busy with figuring out what happened to Vikram.

Isro has a number of data sets to go over – those sent back by Vikram before it went incommunicado just as those possibly captured by different Earth-based space communications devices. Isro is likewise making constant attempts to re-establish communication with the Vikram lander.

What’s next plan to establish a connection with Chandrayaan2?

The space agency also plans to use the Chandrayaan 2 orbiter, which is safe and is revolving around the Moon right now, to map Vikram’s landing site in the hope of finding clues about its fate.

The space agency likewise plans to utilize the Chandrayaan 2 orbiter, which is safe and is rotating around the Moon at this moment, to map Vikram’s landing site in the expectation of finding hints about its fate.

What do you think was Chandrayaan 2  a failure, let’s see.

Has Chandrayaan 2 failed?

Not at all. Landing the rover on the Moon was only one – no matter how ambitious- some portion of the Chandrayaan 2 mission. In fact, the lander Vikram and rover Pragyaan combined carried a lesser number of experiments (five) than the Chandrayaan 2 orbiter, which has locally available eight logical payloads.

Even if the worst was to be assumed – that Vikram and Pragyaan died in the attempt to land on the Moon – a large portion of the Chandrayaan 2 mission’s experiments will stay on course. The orbiter, over the course of its one-year mission life, will play out these experiments and beam the outcomes back to Earth.

Chandrayaan 2 lander goes quiet yet orbiter is where the Moon mission is

In Fact, the one investigation that is most connected with Chandrayaan 2 – estimating the amount of iced water present in the south polar region of the Moon – is to be performed by the orbiter and not Vikram or Pragyaan.

For what reason was the South Pole chosen?

The south polar region of the Moon is an unexplored region full with craters that have not gotten sunlight for billions of years. This is because the angle at which sunlight hits south polar region is such that the craters there have remained permanently under a shadow.

Also, scientists believe that the holes could contain huge amounts of iced water beneath their surface – an energizing prospect that could open up endless potential outcomes for space investigation and further humanity’s understanding of the Solar System.

In fact, the 2008 Chandrayaan 1 mission, which deliberately crashed a probe near the south pole of the Moon, detected signs of frozen water near the area. The Chandrayaan 2 mission is supposed to follow up on those findings.

Returning to Vikram, How is everybody reaction?

As soon as Isro confirmed that it had lost contact with the Chandrayaan 2 lander, voices of support began pouring from all quarters of India. Many said that losing contact with the Chandrayaan 2 lander was not a ‘failure’ since the orbiter was alive and kicking.

Prime Minister console Scientists as follow:

Prime Minister Narendra Modi, who was present at the Isro control center to observe the Chandrayaan 2 landing, delivered rousing, motivating speeches for the Isro researchers.

“Be courageous,” PM Modi told the Isro scientists soon after he was told about contact with Vikram lander being lost. The prime minister came back to the Isro center later in the day and addressed the Isro scientists in an increasingly formal setting.

Narendra Modi stated, “We came very close, but we need to cover more ground in the times to come. Learning from today will make us stronger and better. The nation is proud of our space program and scientists. The best is yet to come in our space program. There are new frontiers to discover and new places to go to. India is with you,” echoing sentiments expressed by Indians across the country.

On the international front, responses poured in from media just as scientists.

Popular astrophysicist Neil deGrasse Tyson called the Chandrayaan 2 mission a “success”. Previous Nasa astronaut Jerry Linenger, on the other hand, noticed how “very, very difficult” it was what India was trying to do. Speaking to news agency PTI, he also called the mission “very successful” generally speaking.

International media, while detailing that Vikram and Pragyaan had in all probabilities crashed on the Moon, held back before considering the mission a total disappointment.


Expectedly, To know what happened to the Chandrayaan 2 lander during its descent on to the lunar surface, the Indian Space Research Organization will be tied up in examining all the data they received.

However, the space agency will also soon get busy with equally ambitious missions and projects it has arranged. These incorporate sending a probe to the Sun, getting ready for the second Mars orbiter mission, investigating the probability of a sending a spacecraft to Venus.

DO you know what is the most ambitious mission in India’s history?

The most ambitious space mission in India’s history is the Gaganyaan mission. Under this Isro will send three Indians to space on an Indian spacecraft. The Gaganyaan mission is a tie-up among Isro and Indian military. The latter will choose and prepare crewpersons for the mission (a procedure that has just started).

While Isro may have endured a setback with the Chandrayaan 2 lander going quiet minutes before its landing. But still, the future for the organization and for India’s space program is bright as ever.
