Chandrayaan-1 was India's first mission to the Moon, launched in 2008. Its objectives were to orbit a spacecraft around the Moon using an Indian launch vehicle, conduct scientific experiments to create high-resolution 3D maps of the lunar surface and map its chemical composition, and have a sub-satellite impact the Moon's surface. The spacecraft was 1.5 meters in size, powered by solar arrays, and carried instruments to examine the Moon's mineral and chemical composition at different altitudes and locations.

1. Chandrayaan -1
Chandrayaan-1 is India's first mission to the Moon launched by India's
national space agency the Indian Space Research Organisation (ISRO).

2. Objectives
• To design, develop, launch and orbit a spacecraft around the Moon
using an Indian-made launch vehicle.
• Conduct scientific experiments using instruments on-board the
spacecraft which will yield the following results:
– Preparation of a three-dimensional atlas (with high spatial and altitude
resolution of 5-10 m) of both the near and far side of the Moon.
– Chemical and mineralogical mapping of the entire lunar surface at
high spatial resolution, mapping particularly the chemical elements
Magnesium, Aluminium, Silicon, Calcium, Iron, Titanium, Radon,
Uranium, & Thorium.
– The impact of a sub-satellite (Moon Impact Probe — MIP) on the
surface on the Moon as a fore-runner to future soft-landing missions.

3. Specification
• Launch date
22 October 2008 from Sriharikota Andhra Pradesh, India
• Mass
