Key Dates Launch: Oct. Scientific goals included the study of the chemical, mineralogical and photogeologic mapping of the Moon. In addition to the five Indian instruments, the spacecraft carried scientific equipment from the United States, the United Kingdom, Germany, Sweden, and Bulgaria.
Finally, the probe successfully entered lunar orbit after a burn that began at UT Nov. Between lunar orbit insertion Nov. The probe fired a small deorbit motor and then went into freefall, sending back readings from its three instruments until it crashed onto the lunar surface at UT near the Shackleton Crater at the lunar south pole.
Chandrayaan-1 experienced abnormally high temperatures beginning late November and for a time, it could only run one scientific instrument at a time. In May , the spacecraft was delivered to a higher mile kilometer orbit, apparently in an attempt to keep the temperatures aboard the satellite to tolerable levels. Chandrayaan-1 also suffered a star sensor failure after nine months of operation in lunar orbit. Instead, controllers used a mechanical gyroscope system to maintain proper attitude. Last contact with Chandrayaan-1 was at UT Aug.
The most likely cause of the end of the mission was the failure of the power supply due to overheating. Magmatic water had been found in samples returned by Apollo astronauts but not from lunar orbit until the operation of the M3 instrument. Featured Resources.
Here’s what happened to Chandrayaan-1
The orbital period was estimated to be around 11 hours. With the successful completion of this operation, India became the fifth nation to put a vehicle in lunar orbit. In this elliptical orbit, Chandrayaan-1 took about ten and a half hours to circle the Moon once. The altimeter then also began recording measurements to prepare for a rover to land on the lunar surface during a second Moon mission. Madhavan Nair.
It operated for almost a year between October and August The lunar orbiter is best known for helping to discover evidence of water molecules on the moon. The Chandrayaan-1 spacecraft was based on an Indian meteorological satellite called Kalpansat. It was about the size of a refrigerator, with a dry weight weight without fuel of about kilograms 1, lbs. Chandrayaan-1 launched on Oct. It reached the moon on Nov.
Chandrayaan Changes made after July 15 launch abort Chandrayaan-1 was carried a range of scientific equipments, both Indian and international, to the lunar orbit. The probe collected a lot of significant data over its mission. During Chandrayaan-1, the Mini-Synthetic Aperture Radar Mini-SAR found water-ice deposits in craters on the far side of the moon which was considered as a significant finding. The Chandrayaan-2 orbiter will circle the moon and provide information about its surface.
