Several facts suggested that the country has acquired a top hosting
position in space technology worldwide. In the wake of Chandrayaan 2, On Sep
07, The National Aeronautics and Space Administration (NASA) has lauded India’s
historic Chandrayaan-2 mission, adding that the Indian Space Research
Organisation’s (ISRO) attempt to soft-land Vikram module on the lunar South Pole
has inspired it and the United State (US) space agency is looking forward to
explore the solar system with its Indian counterpart. However, The US space
agency offer for joint exploration came even as ISRO launch its first mission to
study the sun (Aditya L-1 solar mission).
ISROs first mission to study the sun has a temperature of more than a million
degree Kelvin which is much higher than the solar disc temperature of
approximately 6000K. And how the corona gets heated to such high temperatures is
yet an unanswered question for related scientists in solar physics. Therefore,
the Aditya-1 mission has now been revised to Aditya-L1 mission and will
be inserted in a halo orbit around the L1, which is around 1.5 million km from
the Earth. Thus, the concerned mission has been approved and the satellite will
be launched during 2019 - 2020 timeframe by PSLV-XL.
As per the ISRO plan to soft-land Chandrayaan-2’s Vikram module on the
uncharted South Pole did not go as per script on Sep 07, with the lander losing
communication with ground stations during its final descent. The ‘lander Vikram’
was descending on to the lunar surface as planned and that until 2.1 kilometres
above the lunar surface, its performance was normal. But them, lander to ground
station was lost. Data is being analysed. In this regard, Now ISRO has located
Vikram Lander on the lunar surface, The Indian Space agency have found the
location of Vikram Lander & orbiter has clicked a thermal image of the same.
Top order Scientists are trying to have communicate with Vikram lander by many
ways and it will be communicated as soon as well as possible. Significantly, The
ISRO have an landmark advantage here in order to finding ice and water.
Therefore, The Indian space agency specifically able to look at solidised or
frozen water 10m under the surface of the Moon, and it will create a history.
While all the systems and sensors of the Lander functioned excellently until
this point and proved many new technologies such as variable thrust propulsion
technology used in the Lander.
Following this historic task, May NASAs payload laser reflector array on board
Vikram was meant to track the lenders location and calculate the distance
between Earth and Moon. It could have beamed lasers to various US orbiters in
Moons circular orbit and given data of Vikrams final descent. If Vikram had
broken, The NASA payload would have also shattered as it had a glass component.
Meanwhile, Former NASA astronaut Jerry Linenger remarked, The lessons
learnt from Indias bold attempt to soft land Chandrayaan-2’s Vikram module on
the lunar surface will help the country during its follow up missions.
Therefore, We should not be too discouraged scientists because the country was
trying to do something very, very difficult. In fact, everything was going as
planned as the lander came down. The spacecraft began its journey towards the
moon, leaving the earths orbit on August 14 after a crucial manoeuvre called
Trans Lunar Insertion (TLI) that was carried out by ISRO to place the spacecraft
on lunar transfer trajectory. Only half of the lunar missions involving landing
on moon surface have succeeded in the last six decades, The NASAs officials
According to the United State space agency’s Moon Fact Sheet, There have
been a total of 109 lunar missions from 1958, out of which 61 were successful.
As many as 46 missions involved landing on the lunar surface, including landing
of the rover and sample return. Out of these, 21 were successful, while two were
partially successful. Sample return means mission that involves collecting and
returning samples to earth. The first successful sample return mission was
Apollo 12 of the US launched in November 1969. From 1958 to 1979, only the US
and the USSR (Now Russia) launched Moon missions.
In these 21 years, the two countries launched 90 missions.
There was a lull in the decade that followed with no lunar missions from
1980-89. Japan, the European Union, China, India and Israel have been late
entrants.. The first lunar soft landing and first pictures from the lunar
surface came from Luna 9, launched by the USSR in January 1966. The Apollo 11
mission was the landmark mission through which humans first stepped on the lunar
surface. The three-crew mission was headed by Neil Armstrong. From 2009-2019,
ten missions have been launched of which 5 have been sent by China, 3 by the US,
and one each by India and Israel. Such mission offers an undisturbed historical
position-record of the inner Solar system environment at large.
No impact on upcoming missions: More than 95% mission successful
The Indian Space Research Organisation (ISRO) described this and also explained
the several technological aspects attached to the same. The success criteria was
defined for each and every phase of the mission and till date more than 95% of
the mission goals have been accomplished and will continue contribute to Lunar
science, not with standing the loss of contact with the Vikram Lander. Thus,
Only 5% of the mission has been lost – Vikram the lander and Pragyan the rover –
while the remaining 95% - that is the Chandrayaan-2 orbiter – is orbiting the
The Chandrayaan-2 project will absolutely have no impact on ISROs
ambitious manned mission Gaganyaan, scheduled to be launched in 2022. Meanwhile,
P G Diwakar, who was earlier scientific secretary at the space agency and is now
the Director of Earth Observations Applications and Disaster Management
Programme Office at the ISRO headquarters in Bengaluru, mentioned both
Chandrayaan and Gaganyaan have different objectives and dimensions. There
will be absolutely no problem at all. So it will have no impact. The satellite
missions as well as the human space flight mission will go very smoothly without
any problem. Each mission is of a different type.
Although, The concerned mission is a highly complex mission, which represented a
significant technological leap compared to the previous missions of ISRO to
explore the unexplored south pole of the Moon. Since the launch of Chandrayaan-2
on July 22, 2019, not only India but the whole world watched ISROs progress from
one phase to the next with great expectations and excitement. This was a unique
mission which aimed at studying not just one area of the Moon but all the areas
combining the exosphere, the surface as well as the sub-surface of the moon in
a single mission.
Comparing the Moon mission, Chandrayan-2, with ISROs first mission
Chandrayaan-1, Former scientist at ISRO Pramod Kale mentioned that, India
succeeded in reaching the Moon orbit earlier as well. From there, it continued
and a small impact probe separated and the probe impacted on the Moon surface.
What made Chandrayaan-1 special was the fact that it used spectrometric cameras
and instruments to help scientists in proving that there is water on the Moons
Thus, These kind of space mission will surely help us to achieve a better
understanding of the origin and evolution of the Moon by conducting detailed
topographical studies, comprehensive mineralogical analyses, and a host of other
experiments on the lunar surface. The major vision of the concerned mission are
to demonstrate the ability to soft-land on the lunar surface and operate a
robotic rover on the surface. The Scientific aims include studies of lunar
topography, mineralogy, elemental abundance, the lunar exosphere, and signatures
of hydroxy and water ice.
In Short, The Orbiter will observe the lunar surface and relay
communication between Earth and Chandrayaan 2’s Lander – Vikram. The Orbiter has
already been placed in its intended orbit around the Moon and shall enrich our
understanding of the moon’s evolution and mapping of the minerals and water
molecules in the Polar Regions, using its eight state-of-the-art scientific
instruments. The Orbiter camera is the highest resolution camera (0.3m) in any
lunar mission so far and shall provide high resolution images which will be
immensely useful to the global scientific community.
Consequently, The Vikram Lander is also known as the father of the Indian
Space Programme. And it has the capability to communicate with IDSN as well as
with the Orbiter and Rover. While the Chandrayaan 2’s Rover is a 6-wheeled
robotic vehicle named Pragyan, which translates to ‘wisdom’ in Sanskrit. It can
travel up to 500 m (½-a-km) and leverages solar energy for its functioning. It
can only communicate with the Lander. Although, Chances cannot be ruled out that
it may spot the Pragyan Rover as well as the Vikram lander which will come to a
stand yet after accomplishing the task of assigned experiments.
Yet Not losing hope, the ISRO continued to make all the technical efforts to
establish contact with lander, now lying on the lunar surface after a
hard-landing. As per the location of lander module by Indian Space agency proves
beyond doubt the orbiter is functioning very well and it was only a matter time
that the orbiter located Vikram and the question now remains on the health of
the lander. Also, PM Modi mentioned an ISRO spirit has gripped the country,
which has been united by the moon mission, and the nation now looks beyond
success and failure. On the night of September 7, 100 seconds after 1.50 am an
incident awakened and united the entire country. Like (there is) a sportsman
spirit, an ISRO spirit is running in the country. Countrymen are not ready to
accept negativity. The PM remarked.
