After a profitable mission with Artemis 1 in November, 2022, and with the items of the Artemis 2 structure coming collectively for a launch focusing on late 2024, NASA continues to concurrently push in the direction of the massive objects which can be key to the longer term missions.
One of many greatest excellent feats is on the brink of truly convey people to the floor of the Moon. Overseeing that facet of the missions, beginning with Artemis 3, is Dr. Lisa Watson-Morgan, the supervisor of the Human Landing System (HLS) program working at NASA’s Marshall House Flight Middle in Huntsville, Alabama.
In a sit-down interview with Spaceflight Now amid the von Braun Space Exploration Symposium, Watson-Morgan mentioned getting these landers prepared for his or her debuts on the Artemis 3 and Artemis 5 mission respectively for SpaceX and Blue Origin present each quite a few challenges in addition to distinctive alternatives.
“I believe we’ve got nice, nice challenges in entrance of us,” Watson-Morgan mentioned. “Proper now, at present, I don’t see something that’s stopping us, however that’s at present.”
She pointed to a number of the leaps ahead in rocket capabilities from SpaceX as a barometer for pulling off the lunar touchdown functionality of its Starship rocket. Watson-Mogran additionally famous that the Blue Origin-led group has Lockheed Martin as a companion, which brings experience from the Orion program with it.
“That’s the great thing about our mannequin. We take one of the best of what our authorities does, our experience, after which we take a leap with the technological innovation that trade says, ‘We have to do that so as to save prices and make a enterprise case out of this and provide the worth and the nice value that we’re,’” Watson-Morgan mentioned.
“That’s the place it’s such an engineering artwork in that we’ve got to stability what they should do to achieve success from a enterprise standpoint and guarantee paramount, tantamount that we’re doing all we are able to for crew security. And the crew is lock-and-step with us on each Blue and on SpaceX.”
“Launch is sign”
As much as bat first for the HLS program is SpaceX with Starship. The automobile is the higher stage of the two-stage rocket at present present process testing at Starbase close to Boca Chica Seashore in south Texas.
SpaceX’s method to its launch applications, whether or not its Starship or Falcon, has been a mix of flying, studying, fixing and attempting once more to get it proper. Throughout a hearth chat moderated by Watson-Mogran on Wednesday, Benji Reed, SpaceX’s Senior Director of Human Spaceflight Applications, phrased it as “launch is sign and every thing else is noise.”
“And actually, once we say ‘launch,’ we’re speaking about launching safely, we’re speaking about launching reliably, however you’ve acquired to launch and also you’ve acquired to do so much,” Reed mentioned. “And the attractive factor concerning the Artemis program, and all the totally different gamers and everybody working collectively underneath Artemis, is that each one of those checks and all of those launches and all of those autos and every thing that’s occurring are all a part of that sign of launch and check and go.”
Watson-Morgan mentioned her previous expertise because the deputy director of the Engineering Directorate at MSFC and greater than 30 years as an engineer and supervisor leads her to “totally help and cherish” SpaceX’s method to getting its lander prepared.
Nevertheless, she added that, “I’d be remiss if I didn’t say we’re involved concerning the SpaceX schedule for HLS and the priority is that our crucial path, even at present, goes via these check flights.”
SpaceX acknowledged in a put up on X on Tuesday, following a moist gown rehearsal, that they’re prepared for the second built-in flight check (IFT-2) “pending regulatory approval.” Thursday morning, the U.S. Fish and Wildlife Service (FWS) launched its personal assertion, noting that it formally reinitiated Endangered Species Act session with the Federal Aviation Administration (FAA).
“We now have as much as 135 days to subject an amended organic opinion, however don’t anticipate to take the total period of time,” the company mentioned. The opinion is regarding the water deluge system added to the Starship launch pad following the IFT in April.

Watson-Morgan and her group are desperate to see SpaceX return to flight, stating that they’d wish to see round 15 to 17 launches of Starship en path to the crewed touchdown throughout the Artemis III mission.
She mentioned as a result of SpaceX ticks off a variety of goals with every flight as a substitute of getting every thing finished earlier than launching as soon as, these check flights are crucial for creating the {hardware} that may ultimately be used to help the HLS program.
“Schedule for us is vital and we’re working very intently with SpaceX on guaranteeing that this subsequent check, ensuring that they’re prepared for it, understanding what they hope to realize from it and understanding the chance. And they’re all excessive danger,” Watson-Morgan mentioned.
Watson-Morgan mentioned along with the extra extremely seen flight check marketing campaign, the HLS program and SpaceX have been stepping via a number of the growth milestones wanted to help the model of Starship for the Artemis program.
“We had a cold-start Raptor Vacuum check that was lately accomplished. They’re additionally engaged on smaller thrusters. We’re working via medical equipment testing, coaching system supply, testing crew shows. We’ve labored via how we’re going to deal with mission authority on day of launch,” Watson-Morgan mentioned. “So, in parallel, whereas the world stage sees all these magnificent checks, we’re working intently with SpaceX on all of the mission distinctive objects and milestones and that’s going alongside very easily. And so they truly haven’t missed any of these.”
This week, they’re conducting a docking check. It’s a crucial characteristic, since Starship will first have to have the ability to dock with the Orion spacecraft on the Artemis 3 mission after which with the Lunar Gateway throughout Artemis 4.
Large checks lie forward
In 2024, Watson-Morgan mentioned seeing the propellant switch demonstration goes to be a key issue. That won’t solely exhibit an important piece of SpaceX’s design for the Moon, Mars and past, however it can additionally name upon new belongings for the launch firm which have but to debut.
“That’s the place we’re going to get to see a number of launches from a number of pads go into orbit and switch some quantity of gas between the 2. And that can be a very key indicator as to their readiness degree,” Watson-Morgan mentioned. “And as soon as they get to that time and as soon as that’s achieved, it’s a lot smaller from there on out.”
Waiting for 2024, they will even proceed engaged on objects inside the crew cabin.
“We’re working via flammability testing, to verify, with our oxygen and strain values that we’ll have for our exploration methods,” Watson-Morgan mentioned. “[Checking] that the clothes, the laptops, they’re bagged correctly and what occurs if one thing will get out? So, we’re going via every kind of testing with SpaceX and internally to NASA after which combining our knowledge.”
From Dragon to Starship
Whereas Starship can be a really totally different automobile from SpaceX’s different human-rated automobile, its Dragon spacecraft, each Reed and Watson-Morgan mentioned there may be some overlap between the 2.
As Reed mentioned a number of the challenges they are going to face concerning lighting each whereas on the Moon and in transit to the lunar floor, there are a selection of classes that may be gleamed from Dragon.
“We’ve been docking plenty of Dragons to House Station. We’ve flown Dragon via a variety of lighting circumstances as we undergo the LEO orbit, whether or not it’s going to House Station or a few of our free-flyer missions,” Reed mentioned. “We’ve had plenty of alternatives to develop that.”
Watson-Morgan mentioned whereas standing up the HLS program, she mentioned it was essential to garner experience from the Business Crew Program (CCP), for which the Dragon transports astronauts to and from the Worldwide House Station.
“I obtained plenty of good recommendation to attempt to hold your program workplace small, to maintain some pointed consultants up there and to be very near the choice making. And I’ve adopted swimsuit with that’s precisely how we’re arrange,” Watson-Morgan mentioned. “We’re rising and it’s arduous and I’ll let you know, a number of the days are simply so lengthy, however I do suppose that that has served us properly up to now.”
She added that as they have been creating the contracts for the HLS program, they borrowed one other merchandise from CCP: having “unfettered entry to the contractors’ and the suppliers’ base knowledge so we are able to go search it. And if we are able to’t discover it, we ask, ‘Hey we have to know the place that is.’”
“And so they’re much more responsive as a result of, within the Business Crew days, all that was sort of new and so, there was plenty of looking out to attempt to get the knowledge,” Watson-Morgan mentioned. “As a result of if we are able to get that knowledge to our civil servants, to our authorities group who has plenty of the experience, then we are able to say, ‘Sure, that is acceptable. Use as is’ or ‘No, we have to materials evaluation board this and we have to decide whether or not or not its continues to be usable.”
Blue Origin is “hustling”
Along with creating Starship for the HLS program, Watson-Morgan and her group are actually additionally intently working with the Blue Origin-led Nationwide Staff, which consists of Lockheed Martin, Draper, Boeing, Astrobotic and Honeybee Robotics. They’re creating the Blue Moon Mark 2 (MK2) lander.
It is going to be able to transporting 20 metric tonnes in a reusable configuration and 30 metric tonnes, if it’s solely going a method, in response to John Couluris, the Senior Vice President of Lunar Transportation at Blue Origin. He mentioned throughout the fireplace chat on Wednesday {that a} lighter functionality MK1 lander can be “introduced shortly.”
Whereas the Nationwide Staff wasn’t formally introduced on board till Could 2022 when it was awarded the touchdown contract on the Artemis 5 mission, they’ve the identical set of mission necessities as SpaceX.
Watson-Morgan mentioned her group is spending roughly equal time between the SpaceX and Blue Origin-led groups, that are engaged on related, however totally different know-how challenges.
“We now have one group that’s not too terribly massive, however actually sufficiently big to go in and do deeper risk-based perception dives on issues like propellant switch, as a result of each Blue Origin and SpaceX have that,” Watson-Morgan mentioned. “Completely different fuels and totally different architectures, however nonetheless, on the finish of the day if you take a look at it, the cryo-fluid administration goes to be key for each of them.”
“The thermal properties of that’s going to be key to that. After which, how lengthy can they retailer the propellant and hold it on orbit? It’s mainly the identical kind of ability required, though we all know SpaceX is with methane and Blue Origin is with hydrogen.”
Couluris mentioned with the ability to crack that nut can be key not just for their lunar lander, but additionally for future photo voltaic system exploration.
“If we are able to make hydrogen a storable propellant, zero boil-off methods, we’re not solely unlocking lunar assets, however the potential to open up issues, corresponding to NTP (nuclear thermal propulsion) or different propulsion applied sciences that transcend,” Couluris mentioned throughout Wednesday’s fireplace chat.
Watson-Morgan mentioned her group holds weekly perception conferences with Blue Origin and extra typically, if wanted, as they start to work via their milestones, of which, it has accomplished two. A kind of was the supply of what Watson-Morgan known as a “low-fidelity mock-up,” which she known as “unbelievable.”
“I’m so excited to see Blue Origin right here as a result of the entire resiliency and competitors half helps to maintain every of the suppliers – it helps to maintain their consideration and their focus, I believe, on what’s key to us and to NASA, which is a superb profit to the American public too,” Watson-Morgan mentioned.
She added that NASA’s HLS of us are touring to see the mockup in addition to a coaching simulator. Developing within the close to future Watson-Morgan mentioned they are going to start a certification baseline evaluation with the Nationwide Staff, which she described as akin to a system necessities evaluation.
“It’s the place we go in and ensure they totally perceive the necessities set that NASA laid out and we do an analytical evaluation and evaluation and evaluation their analytical evaluation of whether or not their necessities can truly meet what we mentioned the wanted to fulfill,” Watson-Morgan mentioned.
She mentioned that’s developing in two or three weeks and that her group is already reviewing the information forward of that.
“After which early subsequent 12 months, they’re going to have a preliminary design evaluation. So, they’re hustling,” Watson-Morgan mentioned.
Can they pull it off?
Each SpaceX and Blue Origin are off to the races with their landers, however the clock is ticking earlier than they’re wanted to be known as up.
Watson-Morgan doesn’t look previous the sensible hurdles that lie forward for each landers, however stays assured that the thorough work being finished for each will carry the day ultimately.
Throughout her panel look on Wednesday, Watson-Morgan emphasised that NASA method with this partnership is totally different from different undertakings relating to serving to commercialize the Moon. She mentioned to achieve success, they should “get very deep down into how they’re doing issues” and to do this work “upfront.”
“We do it upfront so there usually are not questions or considerations or confusion as to how the system must be constructed to ensure that, afterward, for our group to come back in and have the ability to human-rate the system,” Watson-Morgan mentioned. “So it’s tremendous difficult. It’s tremendous thrilling. And on a regular basis I get requested how do you sleep at night time an I’m gonna let you know, I sleep very properly as a result of I take it someday at a time.”
