Over the past 60 years, scientists have gotten to know the lunar surface in incredible detail.

But how about what’s underneath the surface? Hidden beneath the moon’s layers of dusty

regolith are lava tubes. These subterranean spaces offer scientists hope that we could

one day use them for building lunar colonies, but they’ve never been explored before….at

least not yet. That’s where Asagumo comes in.

-Asagumo is the first walking rover that will be sent to the moon in the next year.

-Asagumo is the latest rover from Spacebit, a space robotics company based in the United

Kingdom. Its set to launch onboard the UK’s first mission to the moon and will be the

first rover ever sent to explore the lunar lava tubes.

-It's small. It weighs just 1.5 kilos and its main uniqueness is it uses legs instead

of wheels. -We’ve used massive wheeled ‘bots as our

means of exploration for years. So why is it time to move into a design with legs?

-We really believe that legs would provide Asagumo a possibility

Lava tubes will present a much more rugged landscape

-Basically, a lava tube is just a long cave

made by lava a long time ago. On Earth we can find lava tubes as well. We really hope

that lava tubes could be used as a really nice place for a sustainable human lunar base.

This lava cave should protect from temperature, from radiation, from small meteorites, and

other potential things that can harm humans. -Because no one has had a chance to explore

these lava tubes yet, there are still many unknowns. But we think they’re there because

of the steep pits or skylights we’ve spotted on the moon’s surface.

Asagumo will be tasked with identifying whether any of these suspected caves could be a suitable

future home for humans. But as Asagumo prepares to take one giant step for robotkind, you

might be wondering: how will its design help meet this ambitious goal?

And during that walk, we will gather  telemetry and a lot of data.

-But there are so many variables  when tackling a design

that involves so many moving parts. (Literally).

-Legs consume a lot of power. You have to have really fancy algorithms that are responsible for stabilization.

So the legs in Asagumo have three degrees

of freedom, and it means that each leg has three motors. So in general, everything makes

-But one of the ways the Spacebit team has

helped alleviate some of these issues is by having Asagumo walk using a specific static

gait, or walking style, that it can adjust depending on the

-It moves one leg at a time and at any given point in time, the robot

can just stop moving any legs and it will stand still. The main disadvantage of this

type of gait is that it's really slow. And the main benefit is that it's really stable.

Even though it’s tiny, the rover still packs a punch. Asagumo has an onboard computer,

Lidar system, radiation and temperature sensors, multi-spectral camera, memory card, Wi-Fi

Also, in case I forgot to mention,  the team outfitted Asagumo

with some artificial intelligence to  make it semi-autonomous.

-Semi autonomous means that it has some  degree of autonomy but it's

not able to plan the full mission by itself.

So when we are talking  about fully autonomous

we are talking about achieving certain goals.

For example, we can say “Hey, walk there.”

-While all of this sounds—and possibly looks— like science fiction,

-The first mission will be a...technical demo.

And after that, we hope that we will be able  to send up to four Asagumos in one mission.

And we hope that in five or 10 years, the moon will be inhabited by a lot of small Asagumos.

-In addition to being a first for the UK,  this mission could be a game changer

for establishing lunar colonies on the moon.

I’ll be keeping an eye out for all of the big  discoveries made by this little bot.

Did you know that the moon is just about 30 Earths away from us?
