On October 16, In an event at NASA HQ in Washington DC, NASA unveiled its new spacesuits. A red, white and blue suit. theses new spacesuit is called the Exploration Extravehicular Mobility Unit (xEMU).
What this new space is big on is mobility. The suit is designed to give more mobility to the wearer.
for instance, it is now possible to move your arms in a circular motion, perform squats and bend down to pick up objects. as Ms. Kristine Davis, a spacecraft engineer who was wearing the suit.
A larger range of motion is vital for the astronauts. The suit has a large piece of metal at the waste called a bearing which aid in providing this greater range of motion. there are 3 more bearings on the legs with a flexion-extension joint at the waist.
Seals in the bearings help protect the suit from the abrasive lunar dust that managed to stick to surfaces and work its way into every nook and cranny during the Apollo missions
This new suit is also designed to fit all astronauts which surprisingly, the former suits which were huge by the way, could not.
The environment in the suit is 100% oxygen and would mean the astronauts no longer have to spend time “pre-breathing” to remove nitrogen from their bodies. The suit can provide accounts with air for about 8 hours and an extra hour in case of incasities.
An orange suit was also showed called The Orion Crew Survival System by Dustin Gohmert, a project manager at JSC. Orion is the replacement for the space shuttle, but, unlike the space shuttle, it’s designed to carry astronauts to the Moon and other targets in deep space.
The main goal of the suit is to protect the astronauts against accidental depressurization.
Mr. Gohmert said: “We can take safe haven in this suit, we’ll seek refuge in here, we’ll keep the body at 8 psi (pound-force per square inch) for a certain period of time, then we’ll drop down to 4.3 psi and we can remain there for six days.”
“That’s no small feat to be able to live in a volume that’s only a couple of inches bigger than your body for six whole days.”
