To carry out the mission, NASA requested further testing of the lander capable of delivering the payload to the moon's surface, which has now been pushed back to 2024.
Astrobotic has been selected as NASA's commercial partner for the development of the lander for this mission in 2020, under its Commercial Lunar Payload Services initiative (CLPS).
A lander is being provided by Astrobotic, and a rover, VIPER, is being developed inside NASA. As part of its mission, VIPER is supposed to determine whether there is water under the surface of the moon and ice at the South Pole of the moon.
“NASA reports that additional tests will help reduce the risk to VIPER's delivery to the Moon,” it said in a statement on Tuesday.
After NASA officials announced that the additional time would be used for 'upgrades' to the water-hunting rover in 2020, this is the second time the mission has been delayed.
Artemis, NASA's moon-return program, aims to return humans to the moon by the middle of this decade through missions such as this one. There is a possibility that water could provide the basis for humans to live on the lunar surface for a long time, and even serve as an essential element for human space exploration into the solar system's deeper reaches.
The CLPS contract is Astrobotic's second. Astrobotic will be using a smaller, separate lander, called Peregrine, to deliver payloads to the moon potentially this year for the first contract, which was awarded in 2019 for $79.5 million.
The Peregrine is a little over six feet tall and eight feet wide, with a weight capacity of 120 kilograms. In addition to being double the height and nearly 15 feet long, Griffin is capable of delivering 500 kilograms of VIPER to the moon.
With a total weight of 450 kilograms and a size similar to a golf cart, VIPER utilizes nearly every bit of Griffin's payload capacity.
A three-foot drill and three instruments are being used by NASA inside the robot to examine lunar soil for signs of ice. During its mission to the moon, the rover will be able to make its way into the permanently shadowed regions, which are extremely cold.
VIPER's work will allow NASA to map ice concentration and location beneath the surface, something NASA confirmed back in 2009.
Adding $67.8 million to Astrobotic's total contract value of $320.4 million, NASA will be paying the company for the tests. As part of the contract, SpaceX was selected to launch the payload to space using a Falcon Heavy rocket.
