Early subsequent month, a robotic lander will arrive on the Moon’s south pole bearing an eclectic suite of payloads to seek for subsurface water ice. Intuitive Machines’ IM-2 is concentrating on a landing at 84.6° south latitude, simply 100 miles (160 kilometers) from the pole. It is going to deploy an ice-mining drill and mass spectrometer, a miniaturized rover, and a singular “hopper” craft to discover the inside of a completely shadowed crater for the primary time.
The six-legged Nova-C lander will journey atop a SpaceX Falcon 9 rocket from Pad 39A at Florida’s Kennedy House Middle throughout a four-day launch window that opens on Wednesday, Feb. 26. And like earlier missions from this hallowed launch complicated — together with Apollo 8 (the primary crew-carrying Moon voyage) and Apollo 11 (humanity’s first crewed lunar touchdown) — IM-2 will carve its personal area of interest and add its personal raft of historic firsts.
An on-time launch and lunar transit will place IM-2 for a March 6 touchdown at a ridge close to the 13-mile-wide (21 km) diameter Shackleton crater. Whereas the towering peaks round its rim take pleasure in near-continual daylight, its inside is perpetually shadowed and should harbor water-ice. Shackleton was initially picked in 2022 as a possible touchdown web site for Artemis 3, the primary human lunar touchdown since Apollo. Though it’s now not on the listing for touchdown websites, the ridge continues to be close to different potential deployment areas.
Industrial accomplice
Texas-based Intuitive Machines is certainly one of 14 industrial companions chosen by NASA for the Industrial Lunar Payload Companies (CLPS) — a $2.6 billion initiative unveiled in Might 2018 to encourage business to construct robotic landers and fly payloads to the Moon. Intuitive Machines was chosen as a CLPS accomplice in November 2018 and has since gained 4 NASA contracts for a quartet of missions by means of 2027.
The agency’s in-house-built Nova-C lander stands 14.1 toes (4.3 meters) tall and 5.2 toes (1.6 m) extensive throughout its hexagonal body — the scale of a small automobile. It could actually carry as much as 280 kilos (130 kilograms) of payloads to the lunar floor. Its 3D-printed VR-900 motor was the primary methane/oxygen-fueled engine ever fired in deep area when it was lit on the IM-1 mission in February 2024.
Three photo voltaic panels — one on the lander’s high deck, plus two body-mounted arrays — afford 200 watts of electrical energy for a floor lifespan of a full lunar day, or about two weeks on Earth. Battery limitations imply Nova-C can’t survive the frigid two-week lunar night time, when temperatures fall from daytime highs of 250 levels Fahrenheit (120 levels Celsius) to lows of –208 F (–130 C).
For IM-2, Intuitive Machines has given its Nova-C lander the title Athena, honoring the traditional Greek goddess of knowledge. (The IM-2 mission crew has affectionately shortened the title to Addy.)
Middling success
Intuitive Machines’ first mission final 12 months delivered combined outcomes. IM-1, carrying 10 science and know-how payloads for NASA, academia and business, grew to become the primary U.S. spacecraft to land on the Moon since Apollo 17 in December 1972. Named Odysseus after the Greek hero of the Trojan Struggle, IM-1 made the primary ever lunar touchdown by a business car and the closest to the south pole, at 80.13° south latitude.
Nonetheless, a security change on Odysseus’ main laser rangefinder was not activated earlier than launch. A crucial a part of IM-1’s navigation toolkit, it facilitated correct altitude and velocity information throughout descent to the Moon. Floor groups enacted a number of in-flight workarounds to resolve the issue — however Odysseus landed quicker than anticipated, skidding alongside the floor, breaking certainly one of its legs and toppling over at an ungainly 30° angle.

Some scientific information was returned however Odysseus ultimately misplaced energy and shut down at lunar dusk. A post-mission assessment recognized 85 technical points, all of which the corporate thinks it has resolved. However success on IM-2 isn’t assured. “Spaceflight is tough — touchdown on the Moon is extraordinarily troublesome,” Trent Martin, Intuitive Machines’ senior vp for area programs, advised reporters at a media teleconference earlier this month. “You by no means know what might occur.”
By the point IM-1 flew, IM-2 was nearing completion. The mission’s origins date to October 2020, when NASA awarded Intuitive Machines a $47 million contract to ship its 88-pound (40 kg) Polar Sources Ice Mining Experiment (PRIME-1) to the lunar south pole, the place completely shadowed craters might maintain giant portions of water ice — a key useful resource in enabling in humanity’s future exploration of the Moon.
An underground search
PRIME-1’s two devices — the Regolith and Ice Drill for Exploring New Terrain (TRIDENT), constructed by Honeybee Robotics, and NASA’s Mass Spectrometer Observing Lunar Operations (MSolo) — will drill into the floor, looking for water ice and measuring liberated volatiles. A rotary-percussive drill with carbide tooth tougher than metal, TRIDENT will spin and hammer its means as deep as 3 toes (1 m) into the regolith.
“We’re going to go down in roughly 10 centimeter (3.9 inches) “bites” … You’re capturing the regolith on the flutes of the drill,” defined Jacqueline Quinn, PRIME-1’s principal investigator and an environmental engineer at NASA’s Kennedy House Middle. “Then you definitely’re going to deliver that drill again as much as the floor … and through that technique of elevating the drill, it passively pushes previous a brush and the brushing mechanism principally flings the regolith onto the floor.”
The outcome might be a collection of conical piles of excavated lunar materials from more and more larger depths which MSolo will analyze for the presence of volatiles. “Every time we deposit the ten cm (3.9 inches) on the floor, we’re getting numerous key geotechnical information and we’re additionally getting any volatiles information from the method of sublimation of gases,” added Quinn.
Because it drills, PRIME-1 may also furnish insights into the forces wanted to excavate lunar materials, in addition to floor temperatures, power necessities and the effectiveness, reliability and conduct of energy instruments on the Moon. It was constructed as a precursor for NASA’s Volatiles Investigating Polar Exploration Rover (VIPER), a mission to seek for water-ice on the lunar south pole however cancelled final summer season — in a improvement that shocked scientists — on account of price and schedule overruns.
Delivering payloads
Along with the mission’s fundamental payload of PRIME-1, IM-2 is carrying an array of different scientific experiments.
Lunar Outpost’s 22-pound (10 kg) Cell Autonomous Prospecting Platform (MAPP) is a tiny rover that can enterprise 1 mile (1.6 km) over the floor, speaking immediately with Athena and Earth through a high-bandwidth 4G/LTE mobile community supplied by Nokia. MAPP will collect samples for NASA underneath a contract value simply $1 — a symbolic incentive for rising business area industries to entry lunar sources.
Shifting at a high pace of 0.2 mph (0.32 km/hr), MAPP and its hosted payloads will map the native terrain, capturing stereo imagery and thermal information and analyzing samples of regolith in a particular bin connected to its wheels.

Additionally aboard IM-2 is Intuitive Machines’ Micro-Nova Hopper, which can separate from Athena after touchdown and function a standalone drone, exploring difficult-to-reach areas utilizing tiny hydrazine thrusters to propel itself throughout quick distances. Named Grace after U.S. Navy rear-admiral and pc pioneer Grace Hopper (1906–1992), it would carry out 5 quick flights — or “hops” — together with one right into a completely shadowed area inside a crater — a primary for any spacecraft.
The hopper can carry payloads as much as 2 kilos (0.9 kg) throughout distances of 1.5 miles (2.4 km) for high-resolution surveys of the Moon. Like MAPP, it would transmit information and pictures through the Nokia mobile community to Athena.

Its first hop will attain a peak of 65 toes (20 m) with two extra hops aiming to succeed in 165 toes (50 m) then 330 toes (100 m). On its fourth and fifth hops, it would leap out and in of a completely shadowed area inside a 65 feet-deep (20 m) crater. Assuming IM-2 lands on course, the crater — recognized solely as Crater H — must be 1,300 to 1,650 toes (400 to 500 m) from the touchdown web site. Temperatures contained in the crater might dip as little as –370 F (–223 C).
“As soon as within the crater, if we’ve communication, we’ll proceed to speak with Gracie,” stated Martin, referring to the craft by its nickname. “We imagine, primarily based on our discussions with Nokia, that we’d really nonetheless have communications down inside that crater.”
If not, after 45 minutes, Grace will hop again out of the crater utilizing its personal energy. Drone-like units like IM-2’s hopper are anticipated to show helpful for future missions the place deep, steep areas are rendered inaccessible to people or rovers.
Different IM-2 payloads embody Lunar Trailblazer, a NASA probe that can map the distribution of water-ice throughout the Moon; Japan’s 1.1-pound (0.5 kg) Yaoki mini-rover; and the primary flight of Spaceflight, Inc.’s Sherpa EScape (Sherpa-ES) area tug to the Moon.
After launching IM-2 later this month, Intuitive Machines will proceed pushing forward with different missions. In late 2025, IM-3 will land on the equatorial Reiner Gamma web site to research the mysterious floor phenomenon often known as lunar swirls. And in 2027, IM-4 will ship a European floor drill and different payloads to the Moon’s south pole.
