CAPSTONE definition

WASHINGTON: The US space agency NASA has said that a spacecraft sent to research the lunar orbit has reconnected with the agency.

The space agency said on Wednesday that the spacecraft, built at a value of 27 32.7 million, made a successful and partial connection after it left Earth's orbit on Monday, after which the connection was lost.
Launched from New Zealand on June 28, the spacecraft has been orbiting the planet for a few week.
Weighing in at about 25 kilograms, this microwave oven-like satellite are going to be the primary spacecraft to check an elliptical orbit round the moon. this can be the orbit where NASA wants to send its gateway outpost.
The gateway will function an area where astronauts will stop before landing on the moon.
In this orbit, the gravity of the planet and also the moon is balanced, so a small movement is required to stay the satellite or satellite in constant contact with the planet.

This spacecraft called capstone.
