SpaceX, Blue Origin share new lunar touchdown profiles

With NASA’s first lunar touchdown for the reason that Apollo period only some years away, the house company has but to find out precisely how its astronauts will attain the moon.

On Thursday, a NASA spokesperson told CNBC that each Blue Origin and SpaceX — which has been growing its Starship human touchdown system (HLS) for the mission, Artemis 3, since 2023 — have submitted revised touchdown architectures that would speed up the company’s timeline.

The spokesperson mentioned NASA would lengthen its request for proposals to the broader house trade as soon as the federal authorities reopens. A bunch of material consultants would then weigh in on the revised architectures.

NASA in December 2024 forecast that Artemis 3 would launch in mid-2027. Though it has not formally modified that projection, interim NASA Administrator Sean Duffy final week appeared to put it doubtful, saying that the mission would fly a “couple years after” Artemis 2 in 2026.

Duffy appeared on CNBC’s Squawk Box, throughout which he announced the reopening of the contract awarded to SpaceX and the Starship HLS. The latter was assigned to each Artemis 3 and a subsequent lunar touchdown, Artemis 4. If all HLS contract targets are met, SpaceX stands to realize $4.5 billion.

About $2.7 billion of that cash has already been paid out for hitting 49 milestones tied to the contract, the corporate mentioned in a lengthy update on Thursday. Among them are demonstrations of the HLS life help, thermal management, docking, and touchdown methods. It additionally mentioned it has begun constructing a flight-capable HLS cabin with useful methods that shall be used for testing and crew coaching.

Not so quick…

Duffy final week mentioned that SpaceX is “behind” on HLS improvement, opening the door for a competitor comparable to Blue Origin to step in. Blue has its personal HLS contract to launch its Blue Moon Mark 2 (Mk2) lander on the Artemis V mission. It stands to win $3.4 billion if all milestones are met and has acquired about $835 million to date.

SpaceX’s gargantuan Starship rocket, round which Starship HLS is predicated, has accomplished 11 take a look at flights, some extra profitable than others. It has demonstrated just a few vital capabilities, such because the catch and reuse of a number of Super Heavy boosters. But more work is required for it to be human-rated, comparable to an orbital propellant switch demonstration that was initially deliberate for this yr and is now anticipated in 2026.

Blue Origin, in the meantime, has solely accomplished one take a look at flight of its New Glenn rocket, which is able to combine with Blue Moon. But the corporate may ship an uncrewed Blue Moon Mark 1 (Mk1) lander to the moon as quickly as this yr, Jacqueline Cortese, Blue Origin’s senior director of civil house, said this week.

Current plans name for each landers to be flown to lunar orbit earlier than the Artemis 3 astronauts raise off in NASA’s Orion capsule, strapped to its Space Launch System (SLS) rocket. Orion and SLS would transport the crew to lunar orbit, the place they might board the HLS and trip all the way down to the floor of the lunar south pole. There, the lander would function an outpost for exploration.

Both corporations’ plans depend on the provision of an orbital propellant depot, which might gas up their autos on the way in which to the moon. Stocking that depot itself would require an unknown variety of tanker missions.

Lunar duel

Blue Origin didn’t instantly reply to FLYING’s request for details about its Artemis 3 touchdown structure. SpaceX, although, made its emotions concerning the renewed competitors public.

“We’ve shared and are formally assessing a simplified mission architecture and concept of operations that we believe will result in a faster return to the Moon while simultaneously improving crew safety,” it mentioned in Thursday’s replace.

The firm added that Starship is “singularly capable of carrying unparalleled numbers of explorers and the building blocks they’ll need to establish the first outposts on lunar and other planetary surfaces.” It additionally had the “highest technical and management ratings while being the lowest cost by a wide margin” amongst Artemis 3 HLS proposals, SpaceX mentioned.

Per the corporate, Starship is “unmatched” as an Artemis 3 candidate as a result of its massive measurement and reusability.

Starship HLS is projected to face simply over 50 meters tall, in comparison with Blue Moon Mk2’s top of about 15 meters. SpaceX has additionally demonstrated the reusability of Starship’s Super Heavy booster—a feat it hopes to copy with the ship itself in 2026. New Glenn’s first stage is deliberate to be reusable, although Blue Origin has but to show it.

More work to be achieved

SpaceX mentioned Starship’s improvement is “moving at a historically rapid pace.” It has produced greater than three dozen ships and 600 Raptor engines. But it too has loads left to show.

The largest take a look at would be the orbital propellant switch demonstration. Because Starship is so massive, it might want to cease at an orbital depot to refuel earlier than heading to lunar orbit. An unspecified variety of Starship tanker variants shall be used to inventory it.

On the car’s third take a look at flight, SpaceX internally transferred about 5 metric tons of cryogenic liquid oxygen between tanks. Now, it should achieve this between ships.

An preliminary Starship will launch and spend an “extended time” on orbit to gauge how the car performs and monitor any propellant boil-off. Then, a second ship will meet it on orbit for the switch. The rendezvous will depend on DragonEye sensors which have docked SpaceX’s Dragon capsule to the International Space Station dozens of instances. The sensors have undergone separate testing to judge their integration on Starship.

SpaceX on Thursday mentioned the demonstration is focused for 2026. But its timing will rely upon the rollout of its Version 3 (V3) Starship.

The V3 is bigger and extra highly effective than the rocket’s preliminary configuration and the Version 2 (V2) autos that flew this yr. It will introduce bigger propellant tanks, upgraded Raptor engines, and the flexibility to deal with as much as 150 metric tons of payload. It can also be geared up with ports that can enable V3 ships to dock with each other.

Artemis 3 is just not the one incentive for SpaceX to ramp up actions with the V3. The new variant is predicted to be able to orbital missions, together with the launch of Starlink satellites and small telescopes. The firm mentioned it has invested billions of {dollars} into constructing 5 Starship launch pads throughout Texas and Florida. It additionally owns greater than 5 million sq. ft of producing and integration house.
