Would they build two rovers at same time?. Means they have spare for 2nd mission if there are problems with this one. Even if mission is success may want second mission to collect additional data.
Probably a lot of flight spares which would help build a second one later. Going to more than one place would be useful in the long run.
This was a vigorous selection process and I want to thank everyone for their hard work. We reviewed 7 proposals from our robust Commercial Lunar Payload Services (CLPS) pool. Stay updated on future commercial @NASAMoon announcements: https://www.nasa.gov/content/commercial-lunar-payload-services
Surprising that the Griffin used M20 as fuel but the smaller Peregrine lander uses MMH.

Now Tony Colaprete on VIPER.
Colaprete -- PDR scheduled for Aug 26-27. Launch in November 2023.
Colaprete -- VIPER required measurements
Colaprete -- VIPER dimensions. It is solar powered. MER-sized, about 450 kg.
Colaprete -- we have a ride! New paradigm. Astrobotic will deliver us on Griffin lander. Going very well.
Tony Colaprete VIPER An overview of the mission conducts exploration science, the model itself after some applied science applications. About a week 1st major design review Launch set for Nov. 2023
#NASA #PAC - Tony Colaprete #VIPER Viper timeline
A NASA rover mission to look for ice at the south pole of the moon has passed a key review, but now costs significantly more than previously advertised.[...]NASA didn’t disclose the reason for the cost increase, but NASA officials said in June 2020 that they were postponing VIPER’s launch by about a year to late 2023 to change the rover’s design so it can meet the goal of operating for 100 days on the lunar surface. At the time, the agency declined to comment on VIPER’s cost.
We're going to the Moon again - this time with @SpaceX! Falcon Heavy will carry our Griffin lunar lander to the Moon in late 2023 along with NASA’s water-hunting Volatiles Investigating Polar Exploration Rover (VIPER).
Our VIPER Moon rover will roam the Moon's surface in search of water ice. The mission, launching in late 2023, will bring us a step closer to our goal of a sustainable human presence on the Moon under our #Artemis program:
VIPER progress continues moving full speed ahead. NASA’s investment in the mid-size rover for mission development costs and operations is $433.5 million. The current delivery contract value for Astrobotic to deliver VIPER to the Moon through CLPS is approximately $226.5 million.
What happend with PDR? We are waiting for this for the last several years.
I’m very proud to share that the VIPER team held a successful preliminary design review, or PDR, and the recent, successful confirmation review, known formally as key decision point C, shows the VIPER project team successfully demonstrated to NASA leadership that it can meet all the requirements with an acceptable level of risk within cost and schedule restraints. This confirmation clears the way to officially implement the final design of the rover, putting the mission an important step closer to launching to the Moon’s South Pole in late 2023.The VIPER team now continues to detail our design baselined at the PDR, as it looks towards the next major milestone, critical design review, in the fall of 2021.- Dan Andrews, VIPER project manager
