A robotic lander named Athena is poised to make its remaining descent to the moon’s floor, doubtlessly marking the second lunar landing for a U.S. firm this week.
Houston-based Intuitive Machines, which final yr grew to become the primary private-sector firm to soft-land a automobile on the moon, mentioned that its Athena spacecraft is on observe to the touch down round 11:30 a.m. CT (12:30 p.m. ET) Thursday, in accordance with a latest social media publish from the corporate.
A reside stream of the occasion, cohosted by NASA and Intuitive Machines, is ready to start about an hour earlier than touchdown.
If profitable, the 15-foot-tall (4.6-meter-tall) Athena will be part of a lunar lander developed by one other Texas-based firm – Firefly Aerospace of Austin suburb Cedar Park – on the floor of the moon. Firefly’s Blue Ghost automobile made a secure, upright landing early Sunday morning.
Each Athena and Blue Ghost are anticipated to function on the moon’s close to facet, however the two spacecraft can be perched roughly 2,000 miles (3,200 kilometers) aside, with Blue Ghost close to the lunar equator and Athena located near the south pole – nearer than any astronaut or automobile has ventured earlier than.
Lunar landings are exceedingly tough feats. About half of all makes an attempt, together with these by authorities house companies and industrial firms, have led to failure.
Early Thursday morning, Athena accomplished an engine burn that set it on a trajectory out of lunar orbit and towards the floor, Intutive Machines mentioned. The lander then started coasting for about an hour. It should head into remaining descent later this morning and start relying sensors and cameras to navigate the crater-riddled terrain.

A non-public lunar lander carrying a drill, vacuum and different experiments for NASA touched down on the moon Sunday.
Throughout its remaining descent, the automobile should quickly shed pace, decreasing its velocity by about 4,000 miles per hour (1,800 meters per second) earlier than hitting the bottom.
The moon’s south pole is taken into account essential to the fashionable house race as a result of scientists imagine it’s residence to huge shops of water ice. The ice may very well be transformed to consuming water, breathable air and even rocket gas for missions that journey deeper into the cosmos.
Athena is slated to land at a 60-mile-wide (100-kilometer-wide) plateau known as Mons Mouton – which lies about 100 miles (160 kilometers) from the lunar south pole. Then, the lander will get to work.
Athena is on a scouting mission of types. The automobile will use an array of robotic tools – together with a drill, hopper and rover – to scour the close by space for affirmation that water ice is saved throughout the area.
The lander is anticipated to function for 10 days earlier than lunar dusk plunges it into darkness, rendering the spacecraft inoperable.
A shot at redemption
Earlier than Intuitive Machines made historical past final yr when its first lander, Odysseus – or “Odie,” because the startup’s workers known as it – made a gentle landing on the moon, solely a handful of presidency house packages had pulled off that feat. The USA, China, India, Japan and the previous Soviet Union have been in that unique membership.
However Odie’s journey, which additionally ventured close to the south pole area, wasn’t excellent. Earlier than touchdown, mission groups discovered that the laser rangefinder designed to assist navigate the lunar terrain and exactly measure altitude was not appropriately hardwired.
That misstep pressured the corporate to depend on an experimental NASA payload, which occurred to be on board, for navigational help to achieve the lunar floor.
In the end, Odie tripped onto its facet, leaving helpful communications antennae and photo voltaic panels pointed in inopportune instructions. In consequence, Odie powered down days sooner than deliberate.
Firefly briefly alluded to Odie’s wayward orientation throughout reside protection of its moon touchdown this week, declaring that its Blue Ghost lander was the “first absolutely profitable” industrial automobile to the touch down on the moon.
Nonetheless, the businesses have expressed help for one another.
“I will let you know one thing that’s extra thrilling now than another time in historical past is what number of missions are flying to the moon,” Intuitive Machines CEO Steve Altemus advised CNN in February. “Two Texas firms flying landers to the moon that theoretically can be on the floor on the similar time working totally different missions on the moon – that is simply unimaginable for the USA.”
Firefly and Intuitive Machines are each contractors beneath NASA’s Business Lunar Payload Companies program. The CLPS program goals to spur personal trade to develop comparatively low-cost robotic spacecraft that may discover the lunar floor earlier than NASA sends its astronauts there later this decade.
NASA’s Artemis III mission goals to land people on the moon for the primary time in additional than 5 a long time by mid-2027.
Athena’s mission on the moon
Hours after touching down Thursday, the Athena lander is anticipated to deploy a rover it is carrying that is known as Cell Autonomous Prospecting Platform, or MAPP, and constructed by Colorado-based firm Lunar Outpost. The four-wheel, 22-pound (10-kilogram) automobile will check new mobile communications tools, work to create a 3D map of the moon’s floor, and take photos.
The automobile can be designed to gather a small soil pattern. And although the pattern – in addition to the MAPP rover – will keep on the moon indefinitely, NASA has agreed to pay $1 to take possession of the pattern. It is a symbolic transfer meant to mark the first-ever industrial sale of house assets.
Lunar Outpost CEO Justin Cyrus advised CNN that the $1 from NASA is the one authorities funding the corporate will obtain for this mission.

Texas-based Firefly Aerospace made the second personal moon touchdown and the primary absolutely profitable personal moon touchdown in historical past.
“That is our first shot, and the truth that this can be a commercially funded rover with actually $1 from NASA … that is already like a fairly darn good place to be,” Cyrus mentioned.
After MAPP units off, the Athena lander will deploy a miniature hopper – or a spacecraft designed to leap away from the touchdown web site and discover a lunar crater to hunt for water. Intuitive Machines developed that automobile with funding from NASA.
However the major payload on board Athena is NASA’s PRIME-1 drill, which is designed to bear down into the moon’s floor, scour for water ice and analyze the soil because it goes.
If PRIME-1 can find water just under the moon’s floor, it might be “extraordinarily thrilling,” Siegfried Eggl, an assistant professor of aerospace engineering on the College of Illinois Urbana-Champaign, advised CNN this week.
“If the drill would discover just a little little bit of water-rich materials proper (close to) the floor, that would be the best-case state of affairs,” Eggl mentioned, “as a result of it means wherever you go on the south pole, you do not have to dive into craters, you may most likely extract water actually, actually shortly.”
