Proud indian on VIKRAM LANDER AND K SIVAN

Update: ISRO K. Svian announced recently that vikram lander has been spotted by lunar orbit in thermal images which tells that vikram lander has landed on moon surface but sad news is that no communication has been made still, its seem there is some kind of technical issue in vikram lander, ISRO is trying to recalibrate system to link with vikram lander, this news gave hope and joy to whole nation. ISRO explains establishing connection is hard as there is no one to repair or do any manual work if something is broken. K. Sivan said that we are trying our best to communicate with Vikram lander,

Communications were lost with the Vikram moon lander within the last few crucial minutes of the controlled descent. ISRO had success in executing most of the soft landing near to the South Pole of the Moon with the Vikram lander, as a part of the Chandrayaan-2 mission, however, the satellite seemed to shift off track simply towards the tip. A period of confusion followed, where ISRO personnel indicated that they weren’t receiving any communications from the satellite. Officially, ISRO chairman K sivan same, “Vikram moon lander descent was as planned, and normal performance was observed up to an altitude of 2.1 km. later on, the communications from the lander to the ground station was lost. Data is being analyzed.” “There also are some indications from the trajectory that there was an attitude correction manoeuvre“.

The landing was the trickiest part of the mission, and also the most technically sophisticated operation handled by ISRO in its history. One of the first objectives of the mission was to demonstrate the potential of having the ability to execute a soft landing. Those of you who are watching the live stream understand that even at this late hour, the country was awake and getting ready for a celebration. PM Narendra Modi was at the ISRO center in Bengaluru, besides 60 college students from across the country who participated in the ‘Space Quiz’ contest to get an opportunity to be a part of this historic moment.

FIFTEEN TERRIFYING MINUTES

The site of the landing was a high plain between the Simpelius N and Manzinus C craters, at a latitude of 70.9° South and a longitude of 22.7° East. another landing site was 67.7 ° South 18.4° West, and maybe things may have played out otherwise if this site were chosen. Vikram lander had a touchdown speed of two meters per second. Considering the speed, there was an opportunity that the lander may have crashed into the Moon, topple over or be unable to communicate, if things didn’t go precisely as planned. The landing site also had to be carefully chosen to eliminate any probability of Vikram ending up in an area of communications shadow, thanks to the local terrain. prior the launch, chairman K Sivan described the difficult operation, “these fifteen minutes are aiming to be the most alarming for all the people who belong to ISRO, most likely for the scientists {and the|and therefore the|and also the} individuals in India also. this is going to be the foremost tough task ever undertaken by ISRO in a mission”. throughout the whole fifteen minutes, the thruster had to be perpendicular to the surface of the Moon. The ISRO scientists also had to match pictures the pictures from the lander to previous images to make sure that the precise landing site did not have an inclination of over 12 degrees. If the inclination was a lot of, then Vikram would have toppled after the landing. The lander went through thorough drop testing at a specially designed test facility in Chitradurga, that simulated the piece of land of the moon.

The descent operations started from an altitude of 30 kilometers. the whole landing sequence was autonomous, without any command and control from the bottom stations. The algorithms that were necessary to execute the soft landing were entirely developed by ISRO. the ultimate trajectories for the lander were loaded four hours before the descent operation commenced. there have been four phases to the descent, the rough braking section, the angle and absolute navigation management part, the fine braking part, and also the terminal descent part. the primary phase brought down the lander from an altitude of 30 kilometers to 7.4 kilometers, the second phase brought down Vikram lander to 5 kilometers, the third to 400 meters, and also the final phase step by step executes the touchdown, wherever the lander only moves vertically. 800 N of thrust was generated by the four engines on board. The steerable engines performed admirably throughout the controlled descent. sadly, within the third phase of the landing, communication was lost with the Vikram lander. There’s still hope although, it’s going to be possible to restore communications. we don’t yet understand if the lander is simply experiencing a communications drawback, or something else has gone wrong. the information will be got to be analyzed to examine if the formula was liable for the lander to turn off beam, or there was another reason. The four extendable legs on the lander were supposed to dampen the impact and shield the sensitive instruments on board, still as the Pragyaan rover. At this point of time, it’s unknown if the landing was with success executed. more details are anticipated. as the PM noted although, it absolutely was no mean feat by ISRO scientists even to get as far as they did.

PROUD TO BE INDIAN ON VIKRAM LANDER AND K SIVAN.
PROUD NATION ON VIKRAM LANDER AND K.SIVAN

K Sivan has helped us achieve something historic, whole nation support ISRO and K Sivan achievement. We Didn’t lose anything we Learned everything. We THRONEOFGADGET Support and congratulate ISRO and its team.
