MONTREAL, CANADA — My moonwalk was lacking an important factor.
I, untrained as a spacewalking astronaut, felt actually misplaced in house as I fumbled round NASA’s Gateway station circling the moon. I may see the Earth. Canadarm3 was doing its robotic arm factor proper in entrance of me. I may even peek contained in the empty crew modules.
Then I lastly appeared down. There it was. Craters. Lumpy shadows. Goosebumps. The moon within the closeness I had wished to see since I used to be a toddler. Although simulated, the feeling of wanting and exploring round it felt so actual.
Flying jetpack-style round Gateway for about half-hour took nothing greater than joysticks hooked up to an ordinary Meta Quest digital actuality (VR) headset. Dropping into house on the again of this tech solely took moments throughout a media day on the Canadian Area Company (CSA) to promote Artemis 2, a round-the-moon mission with astronaut Jeremy Hansen slated for 2025.
The VR is so highly effective and correct that astronauts might at some point prepare on it, the CSA instructed me. For now, although, the size mannequin on Gateway helps make Canadarm3 the precise dimension, form and match for conserving the house station going with robotic energy.

Canadarm know-how is so well-known in Canada that it graces our $5 invoice. We have had two house robotic arm generations to date for the reason that Nineteen Seventies; Canadarm3 maker MDA says the third will fly to Gateway as soon as 2028 if the orbiting advanced is prepared. Robots not solely preserve house packages going, but additionally fund Canada’s missions — astronauts and house station science alike. So it is a virtuous circle.
After many years of serving to to berth ships, transfer round astronauts and tools and even do the odd photo voltaic array restore, Canadarm’s work will depart low Earth orbit to assist NASA construct out its Artemis program for moon astronauts. The mighty robotic sequence has been known as the “potato salad” of the house program: The unforgettable aspect dish that, just like the rug in “The Large Lebowski,” ties the room collectively.
Canadarm3 can be outfitted with synthetic intelligence and, correctly talking, it isn’t only a single arm. There’s the primary arm tasked with the massive salad gadgets: An eight-jointed spider-like being that may stroll hand over hand on Gateway for repairs. A removable small arm like CSA’s Dextre “helpful robotic” can do finer work, like organising experiments. The set even comes with a backpack, the CSA’s Ken Podwalski instructed me as we sat beside the simulator.
Podwalski, a self-described “dinosaur” who has made Canadarm work his profession for many years, is now govt director for the Lunar Gateway program on the CSA. He makes use of the prehistoric time period with affection and awe, by the way in which.
Not like Podwalski, the 20-something Gen Z engineers exhibiting us across the VR surroundings did not have to make use of paper drawings — or gown up in protecting “bunny fits” in clear rooms whereas strolling round house modules — simply to verify the robotic arm would not brush in opposition to a crucial bit throughout its crawl.
That is particularly essential when the large arm on Canadarm3 is carrying issues, like its backpack or “toolkit.” Like a software caddy, it has slots permitting astronauts or the small arm to mount experiments — or to tote alongside wrenches and such for spacewalks.
“It additionally permits us to have the ability to configure payloads,” Podwalski instructed me. “So if we have now a automobile that arrives at Gateway and brings up a brand new experiment platform, the place we are able to decide that up as a substitute of doing a number of journeys, we are able to truly stack issues into our backpack and cargo up our backpack with these payloads.”

Say a heliophysics or solar science experiment arrives on a cargo ship like SpaceX’s. Scheduling astronaut time is “ridiculous” on ISS missions which have a roomy six months or extra for crew time, Podwalski mentioned. Gateway is even worse, as you would possibly get 30 days should you’re fortunate.
To avoid wasting on bugging the astronauts, the little arm may mount the experiment on the backpack. The massive arm may “do the required choreography” of transferring the solar sentinel to its assigned house station spot. Then as the large arm backs away to do one thing else, the little arm would once more spring into motion so as to add the experiment in simply the precise spot.
Whereas the VR surroundings reveals the present Gateway configuration, together with exhibiting all of the perches for Canadarm3 of their proper spots, Podwalski emphasised it is necessary to herald coaching and real-world expertise as nicely when firming up the arm’s design. Fortunately, Canadarm2 and Dextre have been pairing up on advanced duties for a few years, however the subsequent technology of robots can and may attain farther.
“Once we have been taking a look at Canadarm3, lots of my questions have been straight from the hip: How are we truly going to have the ability to handle that form of vary of movement, whenever you’ve obtained this sort of interference, or whenever you’ve obtained all this crowded stuff across the exterior of the Gateway? Questioning the size of the (massive) arm, questioning the topology of the small arm and all this sort of stuff.”
Questions from folks like Podwalski and long-time Canadarm provider MDA can be essential to maintain issues working far past Earth, on robotics billed on their reliability nearer to dwelling. Even higher, Podwalski pointed to an “instinct” among the many workforce members (who’ve identified one another for many years as nicely) that can be essential in making Canadarm3 prepared for challenges we won’t even predict.
“It is truly one of many issues that we take a look at, after we deliver crew and mission planners and flight controllers and human flight administrators and whatnot” to the CSA, carving worthwhile weeks out of a schedule to get them snug coaching with an arm simulator on Earth. “We deliver them right here to make it possible for (flexibility) will get constructed into their pondering, as a result of that’s how the operations occur. That must be there, proper?”
VR, he added, can be “one of many many instruments” that can be used to get engineers or crew prepared for Canadarm3 operations, in some instances permitting them to coach collectively with out the necessity of flying to Montreal. “The thought is to essentially arrange a coaching surroundings the place we are able to develop our personal sources, to develop whoever we have to give a hit, and try this in probably the most environment friendly manner doable.”
