chandrayaan 2 update

Why everyone is worried for the lander
chandrayaan 2 status

Now it is a 'do or die' situation for the lander(Vikram) because the future is not looking good, it's predictable to be worse because the time period of day and night are different there on Moon then that on the Earth. To break it down into simpler words, a day on the Moon lasts as long as 29.5 Earth days. In other words, if you were standing on the lunar surface it would take "29.5 days" for the Sun to move all the way across the sky and return back to its original position again. so the lander and rover have very limited days of time for them to explore because after that the night will start and it will be unimaginably cold which will affect the condition of the lander as well as the rover because both of them are not designed to bear the cold temperature of Moon.

so let's hope for the best and let's prepare ourself for further missions because this is not the end many great missions and success to come, good luck to ISRO "JAI HIND"

Chandrayaan 2 Lander (Vikram) got found on Moon.

Yes, you heard it right the people at ISRO recently announced that the Vikram lander got found on the lunar surface by the orbiter itself and has clicked the thermal imaging of lander but the communication had to be established, people at ISRO are trying there best in achieving a conversation and will be successful soon. 

The Vikram lander went silent on Friday (Sept. 6) while attempting its first landing on the moon's south pole. ISRO lost contact with Vikram when the lander was just 2.1 km above the lunar surface. The Vikram lander is India's first moon lander and is carrying the country's first lunar rover Pragyan.

Officials at ISRO have not yet released the image of rover Vikram on the lunar surface or described the potential condition of the lander itself. But they have said that despite the lander's presumed failed moon landing, the craft has already demonstrated the key technologies for future missions. 


The Vikram Lander followed the planned descent flight path from its orbit of 35 km to just below 2 km above the surface, Officials at ISRO wrote in an update on Saturday (Sept. 7). "All the systems and sensors of the Lander performed excellently until this point and proven many new technologies.

Chandrayaan 2 landing report

                     Chandrayaan 2 lander 

I expect that we all know about the ISRO Mission of Chandrayaan 2 and here to know about what has happened to the mission, although the mission didn't came out to be entirely successful, as a proud INDIAN i will say that it was a great start for our country to land on the lunar surface.

As per the reports of ISRO all we got to know that after the lander(Vikram) separated from the orbiter it was all going really well and as ISRO told all of us the clock for the most crucial 15 minutes had begun at that time, but after some minutes when the lander(Vikram) was about to touch the lunar surface and was about 2.1 km away the contact suddenly broke between the lander and the command center of ISRO (in Bengaluru, INDIA),  suddenly the entire team started to know the reason behind the break of contact between them but couldn't know the reason, but we can't even say that the lander has been crashed there are still chance that we will get the connection back and our scientists are trying to do there best in doing so and finding other ways.

But we can't say that the whole mission got waste but we still have the orbiter roaming around the moon which will give a lot of information to us and help us to know more about the lunar surface and to map the lunar surface which will be very helpful in the future missions of ISRO and world, and will also tell us information about the availability of water on moon which is our first concern.

when the PM got to the command center of ISRO the chief officer of ISRO Mr.Kailasavadivoo Sivan broke down into tears and PM Modi hugged him, as our prime minister said this is not the end this is a great achievement for INDIA.

The orbiter contains:

• Chandrayaan-2 Large Area Soft X-ray Spectrometer from ISRO Satellite Centre, Bangalore.
• Solar X-ray Monitor from Physical Research Laboratory, Ahmedabad for mapping major elements present on the lunar surface.
• Dual Frequency L and S-band Synthetic Aperture Radar from Space Applications Centre, Ahmedabad for probing the first few tens of meters of the lunar surface for the presence of different constituents, including water ice. SAR is expected to provide further evidence confirming the presence of water ice below the shadowed regions of the lunar surface.
• Imaging IR Spectrometer from Space Applications Centre(SAC), Ahmedabad for mapping of lunar surface over a wide wavelength range for the study of minerals, water molecules, and hydroxyl present.
• Chandrayaan-2 Atmospheric Compositional Explorer 2 (ChACE-2) Quadrupole Mass Analyzer from Space Physics Laboratory (SPL), Thiruvananthapuram to carry out a detailed study of the lunar exosphere.
• Terrain Mapping Camera-2 (TMC-2) from Space Applications Centre (SAC), Ahmedabad for preparing a three-dimensional map essential for studying the lunar mineralogy and geology
• Radio Anatomy of Moon Bound Hypersensitive Ionosphere and Atmosphere – Dual Frequency Radio Science experiment (RAMBHA-DFRS) by SPL.
• Orbiter High-Resolution Camera by SAC for scouting a hazard-free spot for landing. Imagery from OHRC will help in preparing the digital elevation models of the lunar surface.

This is also a big achievement for ISRO as well as INDIA.

As our prime minister said that if in future any poet will write on the chandrayaan 2 mission he would say something like 'The love between the lander and the moon was so strong that the lander couldn't resist to hug the moon and rushed toward the lunar surface' because as we consider moon as a symbol of love.

Now INDIA is looking forward to launching a rover and an orbiter to Mars.

chandrayaan 2 information

Chandrayaan 2, about the mission.


The chandrayaan-2 spacecraft was successfully launched at 2:43 p.m. IST on July 22, 2019, into its planned orbit with a perigee (nearest point to Earth) of 169.7 km and an apogee (farthest point to Earth) of 45475 Km. The launch was done from the Second Launch Pad at Satish Dhawan Space Centre SHAR, Sriharikota.

After the launch of Chandrayaan 2 spacecraft, a series of maneuvers will be carried out with the help of its onboard propulsion system to raise its orbit and place it in the Lunar Transfer Trajectory.

On entering Moon's sphere of influence, on-board thrusters will slow down the spacecraft for Lunar Capture. Subsequently, the orbit of Chandrayaan 2 around the moon will be circularised to a 100 x 100 km orbit through a series of orbital maneuvers.

On the day of landing, the Lander (Vikram) will separate from the Orbiter and then will perform a series of complex maneuvers comprising of rough braking and fine braking. Imaging of the landing region prior to landing will be done with the purpose of finding safe and hazard-free zones. Vikram will try its best to make a soft landing on a high plain between two craters — Manzinus C and Simpelius N — at a latitude of about 70° South on 7th September 2019.

Afterward, the Rover (Pragyan) will roll out and carry out experiments on the Lunar surface for a period of 1 lunar day which is almost equal to 14 Earth days. The total mission life of Vikram is also around 1 lunar day. The Orbiter will continue its mission for one year.

Chandrayaan 2 Name and Pictures

            About the vision of chandrayaan 2

Moving slowly towards the edge of discovery

Chandrayaan 2 is an Indian lunar mission that will boldly go where no country has ever gone before — the Moon's south polar region. Through this effort, the aim is to expand our understanding of the Moon — discoveries that will help India and humanity as a whole. These insights and understandings aim at a pattern shift in how lunar expeditions are approached for years to come — boosting further expeditions into the farthest frontier.


                                                       Why are we going to the Moon?

The Moon is the nearest galactic body at which space discovery can be attempted and documented. It is also a promising testbed to exhibit technologies required for deep-space missions. Chandrayaan 2 efforts to foster a new age of discovery, increase our understanding of space, stimulate the advancement of technology,  promote global alliances, and inspire a future generation of explorers and scientists.



 What are the scientific objectives of Chandrayaan 2? 
Why explore the Lunar South Pole?

Moon provides the best linkage to Earth’s early history. It offers an unscathed historical record of the inner Solar system situation. However there are a few mature models, the origin of Moon still needs added explanations. Extensive mapping of the lunar surface to study variations in lunar surface composition is vital to trace back the origin and evolution of the Moon. Evidence for water molecules revealed by Chandrayaan-1, requires additional studies on the extent of water molecule distribution on the surface, below the surface and in the fragile lunar exosphere to address the origin of water on Moon.
The lunar South Pole is particularly interesting because of the lunar surface area here that remains in shadow is much larger than that at the North Pole. There is a chance of the presence of water in forever shadowed areas around it.
Chandrayaan-2 will try to soft-land the lander -Vikram and rover- Pragyan in a high plain between two craters, Manzinus C and Simpelius N, at a latitude of about 70° south.

MARS ORBITER MISSION (MOM)

THE MOM

Marking India's initial venture into the intergalactic space, MOM will discover and notice the Mars surface features, morphology, mineralogy and the Martian atmosphere. Added, a specific search for methane in the atmosphere will offer information about the odds of the past existence of life on the planet.

                                                      MARS Images Rolled Out by ISRO vs NASA 

The huge distances involved in intergalactic missions present a demanding challenge; evolving and mastering the technologies essential for these missions will open limitless possibilities for intergalactic exploration. After leaving Earth, the Orbiter will have to undergo the intergalactic space for 300 days before Mars capture. Separately from deep space communications and navigation-guidance-control abilities, the mission will need autonomy at the spacecraft end to handle contingencies.
