With about two-and-a-half years to traipse till a deliberate crewed-mission to the moon, NASA is quiet deciding which company will receive a greenlight to make the Artemis program’s lunar terrain vehicle (LTV). On the moment, they’re also looking out for a genuine role of tires. Closing week, the agency opened submissions for its “Rock and Roll with NASA Difficulty,” a competitors to take into sage who can design the upcoming LTV’s four wheels.
A lunar rover doesn’t merely sport a role of broad-sturdy rubber tires. Engineers must take into consideration a out of the ordinary role of challenges in characterize to include definite that the protection of astronauts as they navigate the merciless, dusty lunar terrain at one-sixth Earth’s gravity. Whereas heaps of prototypes exist, the relaxation rover tires to in actuality touch down on the moon arrived on the Apollo 17 mission in 1972. The LTV integrated on NASA’s lengthy-awaited lunar return will need to sage for an identical prerequisites experienced on old visits, whereas also factoring in unique concerns.
“NASA is returning crews to the Moon to establish a lasting, science-driven presence that will abet because the springboard to Mars,” the plight planners defined of their open name announcement. “Central to that ecosystem is mobility, and innovation in mobility will seemingly be key to maximizing exploration returns.”

NASA noted that Apollo’s rovers tripled the differ that astronauts may perhaps well well reach in entirely their suits. After over 50 years of additional learn, discoveries, and technological breakthroughs, the idea is now to traipse where no lunar rover has long past prior to. Artemis cargo landers will speak equipment to web sites along the moon’s polar highlands, whereas crew contributors will total daily sample retrieval runs. Astronauts will even require hasty transit between lunar locales.
“The plight is a constant exchange among traction, mass, provides, and sturdiness,” NASA mentioned.
Artemis’ LTV wheels will need to address off-boulevard lunar expanses coated in plumes of intelligent, electrostatically charged regolith, together with temperatures that step by step swing between -427 and 250 levels Fahrenheit. Whereas the Apollo mission’s moon buggy’s rigid spoke wheels helped max it out at 11.2 mph, NASA’s 14.9 mph chase purpose for the LTV would require a totally diversified design that’s lighter and more versatile.
Innovators possess till 5PM EST on November 4, 2025 to post their entries for Segment 1 of the competitors. Judging will launch up the next day, with a role of 10 finalists to be announced on December 18. A 2nd phase and third phase for additional making an are attempting out will originate on January 2 and Could perchance perchance perhaps 1, 2026, with a stay demonstration from the winner scheduled for sometime that July. If all goes as deliberate (and that’s a huge “if”) the wheels will seemingly be establish in on the LTV accompanying Artemis V in 2030.
“For solvers, the mandate is evident: re-imagine the wheel for the lunar ambiance, that moves faster and works longer than something else created to-date,” NASA mentioned.
