a quadrupole mass spectrometer with a mass resolution of 0.5 amu and sensitivities to partial pressures on the order of 1.3×10−11 pascals. The probe used aluminium-honeycomb sandwich structure onto which the payloads were mounted. The probe was attached to the orbiter with a ball lock separation system which jettisoned the unit from the Chandrayaan. A solid propellant de-orbit mortar nudged the craft out of lunar orbit, while solid propellant based thrusters were fired to spin-stabilize the orientation enabling the imaging system to capture the descent profile. The probe's external surface had four oval-shaped anodised aluminium plates measuring 120mm X 180mm on which the image of the Indian flag was depicted, complete with the Emblem of India and the words "Satyameva Jayate". These plates were attached to each one of the four vertical sides of the probe. As per ISRO specifications these plates had to endure a temperature range from −50 degrees celsius and as high as more than 150 degrees celsius. Mission chronology India launched the Chandrayaan-1 spacecraft using a modified version of the PSLV C11 on 22 October 2008 from Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh at 06:22 IST (00:52 UTC). The lunar probe separated from Chandrayaaan-1, in a 102 km circular polar orbit around the Moon, at 20:06 IST on 14 November 2008. After separation, it first fired its spin up rockets and then its retro rocket to de-orbit itself into the lunar surface. While descending, the MIP continuously sent information back to the Chandrayaan-1 orbiter which in turn beamed the information back to Earth. After a 25-minute descent, it struck the Moon at 20:31 IST, 14 November 2008 at a speed of 1.69 kilometers per second (approximately 6100 km/h or 3800 miles per hour). It crashed into Shackleton Crater, at the lunar south pole, near , at 20:31 on 14 November 2008. Discovery of water On 25 September 2009, ISRO announced that the MIP had discovered water on the Moon just before impact. This announcement was made after the discovery of water was announced on 24 September 2009 by Science magazine by the NASA payload Moon Mineralogy Mapper carried on board Chandrayaan-1. MIP discovered water on the Moon before NASA's Moon Mineralogy Mapper, the announcement of this discovery was not made until NASA confirmed it. This gave the answer to the millennia-old question whether there is water on or in Earth's moon when it led to
