The seek for the next-gen buggy for the upcoming Artemis moon missions has begun.
Whereas the earlier lunar automobiles, used in the course of the Seventies Apollo missions, have been designed for the comparatively balmy local weather of the moon’s equatorial area (or barely north of there), NASA’s Artemis missions are deliberate for the lunar south pole, the place situations are anticipated to be a lot harsher.
NASA has begun the contracting process (opens in new tab) to have personal business construct the following moon rover, formally referred to as the Lunar Terrain Automobile (LTV), which Artemis astronauts will use to traverse the world across the moon’s south pole and past. The brand new draft request for proposals, which is step one within the prolonged contracting course of, has been published (opens in new tab) for business companions to evaluation and touch upon earlier than offering a proper proposal to construct the LTV.

“This draft is among the first necessary steps on this thrilling challenge that may enable astronauts to discover farther on the moon than ever earlier than,” Lara Kearney, supervisor of the Extravehicular Exercise (EVA) and Human Floor Mobility (HSM) Program at NASA’s Johnson House Heart in Houston, stated in a NASA statement (opens in new tab). “Gaining business suggestions is essential as we transfer ahead in issuing a remaining request for proposal.”
The unpressurized rover is anticipated to traverse a whole lot of miles per yr to present Artemis astronauts entry to all kinds of places for prospecting, exploration and scientific analysis. It’s going to even be able to distant management if essential and is anticipated to be obtainable for industrial makes use of when not in service of a NASA operation.
In a response to a query about how the brand new Lunar Terrain Automobile might be totally different from the earlier car used in the course of the Apollo missions, NASA public affairs officer Rebecca Wickes at Johnson House Heart in Houston instructed House.com that “not like the single-mission-use Apollo Lunar Roving Automobile (LRV), the Artemis LTV might be developed with trendy expertise that may enable it to span a number of Artemis missions and carry out remotely commanded analysis in between Artemis crewed missions.”
“The brand new LTV will go farther, last more, and in the end accomplish extra by orders of magnitude in comparison with Apollo missions,” Wickes continued. “As an alternative of ‘proudly owning’ the car, NASA will ‘lease’ it as a service from business vendor(s). This technique will enable NASA to be one in every of many shoppers and nurture a wholesome space business for the American economic system.”
This technique ought to in the end hold the price to US taxpayers decrease than have been NASA to contract out the LTV completely, as was the case with the lunar rovers used in the course of the Apollo missions, which have been deserted on the lunar floor as soon as the missions have been accomplished.
Among the many main challenges confronted by the Artemis astronauts is working in what are referred to as permanently shadowed regions of the lunar floor. The moon’s axis of rotation is almost perpendicular to the sun, so there are craters across the lunar south pole which might be deep sufficient that their bottoms have not seen daylight in additional than 2 billion years.
Along with these lighting situations, there may be additionally the problem of conserving an electrical car working within the excessive chilly of the lunar south pole. This would be the main problem for business hoping to win the brand new NASA contract for the LTV, which NASA plans to contract out as a service from personal contractors reasonably than proudly owning it outright.
