With the Artemis campaign, NASA intends to return humans to the Moon and build a sustainable lunar presence as a foundation for human exploration of Mars. The Artemis II crewed test flight aims to return humans to lunar orbit for the first time in more than 50 years and send its four crew members farther into space than any human has ever gone. Given the high stakes of the first crewed flight, the Agency is working to identify and mitigate any risks and challenges to ensure the safe return of the Artemis II crew and safeguard NASA’s significant investment in Artemis vehicles and systems.

The ISP would be 7000 to 160000.

The “large” system would get to 55-1000 newtons of thruyst with 30 plasma guns and convert about 100 kilowatts into 1-2 megawatts of power. The very large systems with 170 plasma guns could reach gigawatts of power and tens of thousands of newtons of thrust.

 
...a maximum payload capacity of 23,500 kg (51,800 lb) to low earth orbit (LEO) with a fully reusable first stage, and 33,500 kg (73,900 lb) to LEO if fully expended.



The lack of affordable launch capacity in the medium and heavy lift markets is what is driving Relativity Space’s development of its Terran R rocket, according to Chief Revenue Officer Josh Brost.

The company has described its approach as customer-centric, focused on containing costs by 3D printing major parts and designing others to be reusable. And while the 270-foot-tall Terran R is “optimized” for launches to low Earth orbit — about 1,200 miles above the planet’s surface — Brost said the vision is for it to fly more stressing missions to higher orbits.
