Message from ISRO after it lost connection with Vikram Lander of Chandrayaan-2


Vikram Lander was located by the Chandrayaan-2 orbiter, but there is no communication with him yet. Every possible effort is being made to establish communication with the lander.

The space agency received support from across the country. Although it lost communication with the spacecraft before landing, with people from all walks of life praising ISRO. And its scientists for the achievement.

The Lander Vikram, with the Pragyan rover housed inside it, lost communication with ground stations early in September 7. During its final descent, just 2.1 km above the lunar surface. Minutes before the planned moon landing. to re-establish the link have been in progress ever since.

Latest update about Vikram

The country and the ISRO are making every effort not to give up hope of establishing a relationship with Vikram Lander in Chandrayaan-2. But the days ahead are crucial. After three days, things on the Moon’s South Pole will change. Attempts to contact Vikram Lander may fail when the South Pole turns dark after 14 days. 3 hours on the Moon is about three days on Earth.

The moon is now at the South Pole. After three days it will be dark. With this, Isro’s hopes of contacting Vikram Lander will also be in the dark. Because hours later, Vikram Lander is lost in the dark. It may not even be possible to take a picture of Vikram Lander at a later date. Not only ISRO, but no other space agency in the world, including US space agency NASA, can take a picture of Vikram Lander. Not only this, but it will be very difficult for Vikram Lander to be safe on a 14-day dangerous night.

There will be no sunlight on the part of the moon where Vikram Lander is now. The temperature can go up to minus 183 degrees Celsius. At this temperature, the electronic parts of the Vikram lander cannot sustain themselves. If the radio isotope heater unit was installed on Vikram Lander, it could save itself. Because with this system, Lander can be protected from severe cold. That is, all hope of contacting Vikram Lander now seems to be over.

On September 8. ISRO said the landing module was seen on the lunar surface by the camera aboard the Chandrayaan-2 orbital. Vikram made a hard landing. The lander, designed to perform a soft landing. And the rover have a lunar day missionary life, equivalent to 14 earth days.

The space agency, after losing touch with the landing module, had so far said that 90% to 95% of the Chandrayaan-2 mission objectives had been achieved, and would continue to contribute to lunar science despite the loss of communication. with the landing module. He also noted that the need for mission launch and management has ensured a long life of almost seven years rather than planned for the year.

Chandrayaan-2 is India’s second planned lunar mission to be launched in 2019. It is a Chandrayaan-1 follow-up mission that helped confirm the presence of water / hydroxyl on the moon in 2009. Chandrayaan -2 will be launched from the Satish Dhawan Space Center in Sriharikota. India aboard a geosynchronous satellite launch vehicle (GSLV) rocket.

According to the Space Research Organization of India (ISRO), the new mission will consist of an orbiter, a landing module and an explorer vehicle. The orbiter will make a map at an altitude of 100 kilometers (62 miles), while the landing module will make a soft landing on the surface and send the spacecraft.

Initially, ISRO planned to partner with Russia to execute Chandrayaan-2. The two agencies signed an agreement in 2007 to launch the orbiter and the landing module in 2013. However, Russia has abandoned the agreement, according to a report by The Hindu. The construction of the Russian landing module was delayed after the failure of the Phoo-Grunt Rosobosmos mission in December 2011 on the Martian moon of Phobos, according to the report.

Subsequently, Russia withdrew Chandrayaan-2, citing financial problems. Some reports indicated that NASA and the European Space Agency were interested in participating, but ISRO continued the mission on its own.

Chandrayaan-2 will surround the moon and provide information about its surface, said ISRO. “The charges will gather scientific information on lunar topography, mineralogy, elementary abundance, lunar exosphere and hydroxyl and ice water signatures,” said ISRO on its website. The mission will also send a small 20 kg (44 lb) spacecraft to the surface; The spacecraft will move semi-autonomously, examining the composition of the lunar regolith.
