What are the scientific goals of Chandrayaan mission?
The Chandrayaan-1 mission performed high-resolution remote sensing of the moon in visible, near infrared (NIR), low energy X-rays and high-energy X-ray regions. One of the objectives was to prepare a three-dimensional atlas (with high spatial and altitude resolution) of both near and far side of the moon.
What is the main achievement of Chandrayaan-1?
CHANDRAYAAN-1 achievements, the discovery of the presence of Water / Hydroxyl molecules in lunar soil detected by the Moon Minerology Measuring Instrument (M3) of NASA as well as the mass spectrometer in MIP is a major breakthrough that would change the face of lunar exploration.
What is Chandrayaan mission?
Chandrayaan-1 (chandrayaan is Hindi for “moon craft”) was the first lunar space probe of the Indian Space Research Organisation (ISRO) and found water on the Moon. It mapped the Moon in infrared, visible, and X-ray light from lunar orbit and used reflected radiation to prospect for various elements, minerals, and ice.
Is Chandrayaan-1 success or failure?
The spacecraft operated for less than two years: 312 days as opposed to two years. However, the Chandrayaan-1 was successful in achieving at least 95 per cent of its objectives.
What was the scientific objective of Chandrayaan Mission?
Carry out high resolution mapping of topographic features in 3D, distribution of various minerals and elemental chemical species including radioactive nuclides covering the entire lunar surface using a set of remote sensing payloads.
When did Chandrayaan 1 go into a higher orbit?
Chandrayaan-1 experienced abnormally high temperatures beginning late November 2008 and for a time, it could only run one scientific instrument at a time. In May 2009, the spacecraft was delivered to a higher 120-mile (200-kilometer) orbit, apparently in an attempt to keep the temperatures aboard the satellite to tolerable levels.
What kind of propulsion system does Chandrayaan 1 use?
A bipropellant propulsion system is used to transfer Chandrayaan-1 into lunar orbit and maintain attitude. The spacecraft is 3-axis stabilized using attitude control thrusters and reaction wheels. Knowledge is provided by star sensors, accelerometers, and an inertial reference unit.
What was the cause of Chandrayaan 1’s failure?
Chandrayaan-1 also suffered a star sensor failure after nine months of operation in lunar orbit. A backup sensor also failed soon after, rendering inoperable the spacecraft’s primary attitude control system. Instead, controllers used a mechanical gyroscope system to maintain proper attitude.
