Launch of Nasa's Capstone  Delayed to June 13

Cubesat Moon Mission

The launch of NASA's 

CAPSTONE moon mission has been pushed back another week, to no earlier than June 13.

The 55-pound (25 kilograms)

 CAPSTONE spacecraft will lift off atop a Rocket Lab Electron booster equipped with a Lunar Photon upper stage

That liftoff had been

 targeted for June 6. But CAPSTONE  will now get off the ground no earlier than June 13,

CAPSTONE's main goal is

 to test out the stability of a near rectilinear halo orbit round the moon, making sure it's a safe place for NASA's forthcoming Gateway space station

That highly elliptical

 orbit will take CAPSTONE, and Gateway, as close as 1,000 miles (1,600 kilometers) to the lunar south pole

CAPSTONE will also 

conduct some ests with NASA's Lunar Reconnaissance Orbiter, which has been circling Earth's nearest neighbor since 2009.
