- 3755 - ORION SPACESHIP - ready for a trip to Mars. Orion is the only human-rated spacecraft designed for travel to deep space. Not only will it return humans to the Moon, but it may even get them to Mars. Here are 11 little known facts about the spacecraft that's about to make history.
--------------------- 3755 - ORION SPACESHIP - ready for a trip to Mars.
- There’s an exercise machine inside Orion and it’s similar to a rowing machine. The compact flywheel exercise machine is used for aerobic and strength workouts, and works similar to a rowing machine. All four astronauts have to exercise every day to keep from losing bone mass. In order to exercise comfortably and efficiently, the machine will be placed on a 45 degree angle.
-
- The energy dispersed by Orion’s heat shield during re-entry is about the same amount of energy of an Category 3 tornado. The energy exuded by Orion’s heat shield as it comes back into Earth’s atmosphere is approximately 640 giga-joules. This amount of energy dispersed is about two times the amount of energy created by a spacecraft returning from the International Space Station.
-
- Orion’s heat shield will get up to 5,000°F during re-entry, yet the inside will stay comfortable in the 70s. The primary way Orion puts on its breaks before it splashes down is with its heatshield.
-
- As it screams through Earth’s atmosphere, friction and air resistance causes extreme temperatures on the heat shield reaching about 5,000°F during re-entry. These high temperatures are about 2.5 times the temperature of Hawaiian lava and 66% hotter than spacecraft coming back from the International Space Station.
-
- Returning from the Moon, Orion will go 24 times faster than a speeding bullet. Orion will return to Earth from the Moon at a speed of about 24,600 mph or about 7,600 mph faster than a spacecraft coming back from the International Space Station. At this speed, Orion could travel from Los Angeles to New York City in 6 minutes, while a normal flight on commercial airlines takes 5.5 hours.
-
- Orion will travel 1,000 times farther into space than the International Space Station (ISS). The International Space Station orbits 240 miles above the Earth and the Moon is 240,000 miles away, so Orion will takes astronauts 1,000 times farther into deep space than the ISS. And once there Orion will travel an additional 40,000 miles past the Moon during the unscrewed “Artemis I unscrewed” mission.
-
- There are 11 parachutes to slow down Orion in the Earth’s atmosphere and safely land on the ocean. After Orion’s heat shield scrubs off most of the Orion’s speed, the parachute system with its 11 parachutes will slow the crew module during the last part of re-entry from 324 mph to 17 mph for a soft ocean splashdown.
-
- Orion uses is three main parachutes to land, though it can land safely using only two. All three main parachutes combined would cover a football field from 10 yard line to 10 yard line.
-
- The crew systems in Orion are designed to accommodate 99% of the human population. The spacecraft can accommodate astronauts as small as a 4’10” and as tall as a 6’5”.
-
- During the Artemis I mission, Orion will go about 40,000 miles past the Moon. As Orion orbits around the Moon, it will go out beyond 15 times the distance from Maine to San Diego and about 30,000 miles farther than Apollo traveled. At its closes point, Orion will only be about 62 miles above the surface of the Moon.
-
- The computers on Orion are 20,000 times faster than Apollo’s. Orion’s main computers provides significantly faster computing speed over other human spaceflight vehicles. The computing speed of each computer is about 25 times faster than the International Space Station’s computers, 400 times faster than the space shuttle’s and have four independent computers running in parallel for redundancy.
-
- Orion’s crew module is roomy, sleeps four comfortably and has a private toilet. At 315 cubic feet, Orion’s crew module provides 30 percent more cubic volume of space than the Apollo capsule. The seats inside of the crew module fold down and create a lot of room for the four astronauts to live in for up to three weeks. It even has a private toilet, or “hygiene bay,” about the size of one on a small passenger airplane.
-
- Orion can operate in deep space for a long time. Orion has room for supplies and consumables to safely sustain a crew of four for up to 21 days. It can function unattended for six months in orbit when docked to the Gateway at the Moon.
-
- Orion has been evaluated to support a 1,000 day mission to Mars when equipped with additional propulsion, habitats and supplies as part of a larger Mars transport system. Can not wait to try this out. Hope I am around to see it.
