Sending humans into space, even on the moon, is not as easy as launching a spaceship and waiting for a call in Houston. You need to find a way to keep the spaceship afloat and to say that humans are alive.
The NASA Orion spacecraft will take off on the SLS satellite from the space agency to send us to the Moon for the first time since the Apollo era at future Artemis missions (will that be the # 1 39; Artemis era?). The moon is not Orion's final destination, as it will go beyond the moon until NASA claims to be 1,000 times farther away from Earth than the International Space Station. Do this further than any spaceship carrying humans, period. This means that he needs a technology as advanced as his science fiction scouting missions.
Humans need to breathe. Moreover, we must breathe air without anything that could potentially destroy our lungs. Have you ever tried to catch your breath during a disgusting day of moisture and feel the relief of an air-conditioned building? Moisture is only one of the factors to be taken into account when developing a new system that will eliminate moisture and CO2 from the air , which will also facilitate embedded equipment, as water can corrode hypersensitive equipment. And it takes a lot less volume. Missions far from the home planet need maximum space for food and water, for space suits and to allow the crew to stretch their legs.
Propulsion is essential for a vehicle that will continue boldly where … you get it. Orion will have to take 2,000 gallons of propellant for its 33 engines. The main engine will maneuver the spacecraft to the lunar orbit and come out, and has a backup in case it would malfunction en route to the Moon or Mars. The remaining 32 engines will drive and control. Future spacecraft will abandon the propeller and turn water into fuel by breaking it down into oxygen and high-potency hydrogen.
Killer radiation is another thing to take seriously if you venture beyond our atmosphere and the protective layer of ozone that accompanies it. There is no amount of sunscreen (and no specific type of screen that still exists) that can prevent an astronaut from being bombarded with radiation by solar storms and other cosmic phenomena that can cause chronic health problems. disturbances of the computer. The disruption of all that is involved in communication is a big problem. Orion is ready to block intense radiation with radiation sensors, self-checked computers and a back-up plan allowing astronauts to hide in an improvised storm shelter that will be stored under the main deck until needed .
One more thing: GPS does not work outside the Earth. It is for this reason that it is called Global Positioning System. This means that astronauts need a reliable form of navigation to avoid getting lost in space. As Orion will be well outside the realm of GPS and communications satellites orbiting our planet, it will have to switch to use NASA's three communication networks as well as backup communications. It will move from the near-Earth network to the space network, supported by NASA's tracking and data relay satellites, as it moves farther and farther away from Earth, and eventually to the network of satellites. deep space when it is far enough away.
Orion may have been considered science fiction in the Apollo era, but decades later, this state-of-the-art technology became a tangible reality. Too bad that NASA does not reveal the secrets of its dehumidifying magic.
