Chandrayaan 3 - Pragyan Rover Rolling Out on the Surface of the Moon !

Posted On : 25-August-2023 : 01:25PM | Chandrayaan-3 : Pragyan Rover rolls out onto the surface of the Moon !

With the successful landing of the Lander Module of ISRO's third lunar mission Chandrayaan-3, India has reached the Moon! It has also became the first country to land near the Moon's south pole. India becomes 4th country to make soft landing on lunar surface.

#.Lander Module (LM) : Vikram Lander

The Lander Module (LM) of the Indian Space Research Organisation's (ISRO) third lunar mission Chandrayaan-3, launched on July 14, made a successfully landing on the Moon's surface on August 23, making India only the fourth country after the erstwhile USSR, the U.S. and China to make a soft landing on the lunar surface.

Congratulating the team of scientists at ISRO, PM Modi said, 'India's successful moon mission is not India's alone. Our approach of one earth, one family one future is resonating across the globe'. Moon mission is based on the same human centric approach. So, this success belongs to all of humanity.

The officials at the Mission Operations Complex (MOX) at ISRO Telemetry, Tracking, and Command Network (ISTRAC) readied to roll out the rover, which will carry out in-situ chemical analysis of the lunar surface during the course of its mobility.

#.Pragyan Rover !

With the Pragyan rover poised to navigate the moon, its eyes to traverse the crater-filled lunar surface are powered by a software developed by a Noida-based tech start-up.

Omnipresent Robot Technologies, which has been working closely with ISRO for the Chandrayaan series of lunar missions, has developed Perception Navigation Software for the Pragyan rover that is housed in the Vikram landing module that touched down on the moon Wednesday evening

We are very excited and look forward to seeing the Pragyan rover navigating the lunar surface using our software, Aakash Sinha, Chief Executive Officer of Omnipresent Robot Technologies.

Chandrayaan 3's soft-landing achieved, the rover module will now embark on its 14-day assignment to carry out the tasks mandated by the ISRO scientists.

Its duties include experiments to further understand the lunar surface.

According to ISRO, Lander and the Rover have five scientific payloads which have been placed inside the Lander Module (LM).

Rover's Alpha Particle X-Ray Spectrometer (APXS) will be used to derive the chemical composition and infer mineralogical composition to further enhance the understanding of the lunar surface.

Laser Induced Breakdown Spectroscope (LIBS) will determine the elemental composition of the lunar soil and rocks around the Moon's landing site.

The deployment of Rover to carry out in-situ scientific experiments would scale new heights in lunar expeditions, ISRO said

#.International Envoys On Chandrayaan 3 - India's Moon Mission !

As India scripted history on Wednesday, with the Chandryaan-3 successfully performing a soft landing on the moon, the envoys of Israel, United Kingdom, France, Germany and Australia heaped congratulatory wishes.

Israeli envoy, Naor Gilon congratulated India and ISRO for the achievement and said that it has made everyone moonstruck. Heartiest congratulations to @isro and #India on the incredible success of #Chandrayaan3, becoming the first country to land on the Moon's south pole! Your dedication to space exploration makes us all moonstruck, Gilon said on X (formerly Twitter).

British High Commissioner Alex Ellis also congratulated India and said 'Bhadhi Ho'. A big moment for India for the world and. Ellis wrote on X. Badhai Ho Touchdown! Congratulations to India making history with the successful #Chandrayaan3 mission - a giant step forward for the whole world, the British High Commission said on X (formerly Twitter).

The French Embassy also congratulated the people of India calling it soft landing in the history books. Soft landing in the history books Congratulations @isro & the people of India on the #Chandrayaan3 success! Through this landmark feat born of ingenuity and perseverance, India benefits all humankind's space exploration endeavors, the French Embassy stated on X (formerly Twitter).

German envoy to India, Philipp Ackermann also congratulated India calling it a historic day. My heartfelt congratulations to India and Team @ISRO for the successful moon landing of #Chandrayaan3. What a historic day, not only for India, but also for the whole world! Ackermann said on X.

Australian High Commissioner to India, Philip Green also congratulated India and that his whole team was watching the moment live. What a triumph! Congratulations

#.What will happen to Vikram lander and Pragyan rover after 14 days?

The world is celebrating India's achievement in successfully landing Chandrayaan 3 on the moon's south pole. Yet, as the mission unfolds, there are intriguing questions regarding the durability of the Vikram lander after 14 Earth days, equivalent to one lunar day. Here's what we've gathered so far.

After this initial 14-day period, night descends on the moon for the next 14 days. During this lunar night, the Vikram-lander and Pragyan-rover, respectively, remain dormant due to their reliance on solar energy, as they can only operate in sunlight.

Adding to the challenge, the moon's nighttime is unforgivingly cold, with temperatures plummeting to a bone-chilling -208 degrees Fahrenheit or -133 degrees Celsius. Such extreme cold conditions pose a significant obstacle to the smooth operation of the rover, lander, and their scientific instruments.

This unique situation arises because 14 Earth days correspond to one lunar day. Once the lunar night sets in, the situation becomes complex. The solar-powered lander and rover are expected to slow down significantly, raising concerns about the feasibility of sustaining their operations. The cost and resources required to keep these lunar explorers active during this period could become substantial, and it's uncertain whether Chandrayaan 3 has the capacity to endure such an extended lunar night.

However, the scientists at the Indian Space Research Organisation (ISRO) have not ruled out the possibility of Vikram and Pragyan springing back to life when the sun graces the moon's surface once more.

Some enthusiasts in the scientific community assert that Vikram and Pragyan are destined to remain on the moon permanently. The propulsion module, lander, and rover will not return to Earth but will instead become fixtures of the lunar landscape.

During the lunar night, the rover will maintain contact with the lander. This will serve as a relay station for data transmission back to ISRO's mission command center. Nevertheless, direct communication with the rover during this period will not be feasible.

It's worth noting that the strategic landing date of August 23 marked the beginning of a lunar day cycle. ISRO, however, had a contingency plan in case Vikram couldn't make it on that day. The backup landing date would be August 24.
