Artemis II
contained personal spaceship, and
another worn inside the spacecraft during
high-risk parts of a mission such as
inside Orion during launch and reentry
through Earth's atmosphere. NASA is
building both for Artemis missions.
NASA has re-engineered elements of
the crew survival suit worn on the space
shuttle to enhance range of motion and
improve safety for the astronauts who
will wear it to get to the Moon and back
to Earth.
The Orion suit, sometimes called a
flight suit or a launch and entry suit, has
been enhanced from head to toe with
improvements to the suit astronauts
wore on shuttle missions.
Features on the helmet, for example,
allow for improved comfort and function.
The helmet is lighter, stronger,
comes in more than one size, helps
reduce noise, and is easier to connect to
the communications system needed to
talk to other crewmembers and Mission
Control.

orange to make crewmembers easily

ever need to exit Orion without the
assistance of recovery personnel -
includes shoulder enhancements for
better reach and is fire-resistant. The
suit is a pressure garment that includes
a restraint layer to control the shape
and ease astronauts' movements. A reengineered
zipper also allows astronauts
to quickly put the suit on and has
increased strength.
New adaptable interfaces supply air
and remove exhaled carbon dioxide.
The suit has improved thermal management
that will help keep astronauts cool
and dry. A liquid cooling garment worn
underneath the suit - a bit like thermal
underwear with embedded cooling
tubes - was revamped to be more
breathable and easier to build.
While shuttle-era spacesuits came in
off-the-shelf sizes like small, medium,
and large, the Orion suits will be custom
fit for each crewmember and ac -
commodate astronauts of all sizes. The
suits' gloves, the part of a spacesuit that
receives the most wear and tear, are
more durable and touchscreen compatible,
and im provements to the boots
provide protection in the case of fire,
fit better, and help an astronaut move
more nimbly.
Even though it's primarily designed
for launch and reentry, the Orion suit
can keep astronauts alive if Orion were
to lose cabin pressure during the journey
out to the Moon or on the way
back home. Astronauts could survive
inside the suit for up to six days as they
make their way back to Earth.
The suits are also equipped with a
suite of survival gear in the event they
must exit Orion after splashdown
before recovery personnel arrive. Each
suit will carry its own life preserver
that contains a personal locator beacon,
a rescue knife, and a signaling kit
with a mirror, strobe light, flashlight,
whistle, and light sticks.
