The unmanned lunar landing module in India successfully detached from orbit on Monday at the planned landing of the South Polar Moon this weekend, the country's space agency reported.
The orbit and landing gear are "healthy," according to a statement from the Indian Space Research Organization.
The maneuver on Monday removed the lander from the top of the orbit where it was sitting after the mission took off from southern India on July 22nd.  The module has reached a distance of about 100 km from the lunar surface, the space agency said.
He will attempt India's first moon landing on a relatively flat surface on Saturday to study previously discovered water deposits.

Chandrayaan-1 orbits the moon's orbit in 2008 and helps confirm the presence of water.
Space Agency chairman K Sivan said landing a hat on the moon's surface involves a lot of technical complexity – an event he described as "15 horrifying minutes."
If India manages the landing, it will be only the fourth country to do so after the US, Russia and China.
India plans to send humans into space by 2022.
