Nasa wants more testing of the Griffin lander to ensure it can safely deliver the Viper rover to the Moon’s surface
The Viper — Volatiles Investigating Polar Exploration Rover — was scheduled to launch in November 2023, but that launch date will now slip to November 2024. That will allow more time for ground testing the Griffin lander that will deliver Viper to the lunar South pole, de acordo com Nasa statement.
Both Viper and the Griffin lander are made by Astrobiotic, a Pittsburg company Nasa contracted to build the pair through the space agency’s Commercial Lunar Payload Services, ou CLPS programa, which is designed to foster innovation in lunar exploration technology among private space contractors.
“VIPER is NASA’s largest and most sophisticated science payload to be delivered to the Moon through CLPS, and we’ve implemented enhanced lander testing for this particular CLPS surface delivery,” Nasa deputy associate administrator for exploration Joel Kearns said in a statement.
Cerca de the size of a golf cart and weighing just less than 1,000 libras, the Viper rover will use its 3.28 foot long drill to sample lunar regolith and search for water across various types of lunar terrain, including craters where deep shadows could have preserved water ice for billions of years.
Better understanding where water might persist on the Moon, and in what quantities, will help support Nasa’s future Artemis missions. Beginning with Artemis III, scheduled to launch in 2025, Nasa astronauts will explore the Moon’s southern polar region, and may run experiments harvesting lunar water for drinking, washing and creating fuel.
"O [Viper] rover will teach us about the origin and distribution of water on the Moon and prepare us to harvest resources 240,000 miles from Earth that could be used to safely send astronauts even farther into space, including Mars,” Nasa Viper program scientist Sarah Noble said in a statement.
