Chandrayaan-1 has been found: NASA finds ISRO’s missing spacecraft with new, Earth-based tracking system

Chandrayaan-1 was India’s first lunar mission also it was a victorious one. The mission consisted of an orbiting spacecraft plus a lunar impactor. The mission was intended to previous two years, except the Indian Space Research Organization (ISRO) lost contact with the orbiter for almost a year in the process.

It’s now been found.

The Chandrayaan-1 mission shipment was launched as of the Satish Dhawan Space Centre on 22 October 2008 on the ship the PSLV-XL C11 rocket. The orbiter was inserted into lunar orbit on 8 November 2008 and was predictable to remain operational until at least 2010.

Sadly, the orbiter in progress experience technical issues by the star sensors, thermal caring and more. On 29 August 2009, ISRO lost contact with the spacecraft.

While the mission strength comes into view to be an incomplete failure, it must be remembered that this was the mission that established the attendance of water on the surface of the moon.

ISRO lost touch with the spacecraft, but that didn’t mean that the spacecraft had disintegrated or crashed into the surface of the moon. The National Aeronautics and Space Administration (NASA) decided to “find” the Chandrayaan-1 orbiter to examination some new tracking hardware that was being developed.

The tracking hardware involves an Earth-based radar arrangement that NASA has been using to track asteroids. They used this radar to locate the location of NASA’s own Lunar Reconnaissance Orbiter (LRO), but this was easy as they had exact orbital data for the LRO.

ISRO’s Chandrayaan-1 orbiter, though, was incommunicado since 2009 and its orbital decay or drift was unidentified. NASA points out that the orbiter was also very little.

The moon is 380,000 km away from us, not a tiny distance, and the radar had to be very authoritative. NASA used a 70-meter antenna to beam microwaves to the moon and then analyzed the frequent radar echoes as they were conventional on a 100-meter telescope.

NASA scientists predicted the orbit of Chandrayaan-1 and targeted the microwave beam in the area where they predictable to see the spacecraft. They found it. NASA tracked the spacecraft at usual intervals over the way of three months and now has precise data on its velocity and trajectory.

Of course, the spacecraft itself can’t be well again, it’s in lunar orbit after all, but NASA’s result proves that they have the ability to track even tiny spacecraft at huge distances from the Earth.
