NASA’s Lunar Space Station Is a Great/Terrible Idea

NASA’s orbiting Lunar Gateway is either essential for a moon landing or a boondoggle in the making

When astronauts first landed on the moon a half century ago, they went there in a single shot: A Saturn V rocket launched the Apollo command and service module and the lunar lander, which entered into a low orbit around the moon. The lander then detached and descended to the surface. After 22 hours in the moondust, the Apollo 11 astronauts climbed into the lander’s ascent stage and returned to the command module for the trip back to Earth.

NASA’s current plan for sending astronauts back to the moon, which may happen as soon as 2024, goes a little differently. A series of commercial rockets will first launch the components of a small space station, which will self-assemble in high lunar orbit. Then another rocket will send up an unoccupied lunar lander. Finally, a giant Space Launch System (SLS) rocket will launch an Orion spacecraft (which looks a lot like an Apollo command module), with astronauts inside. Orion will dock with the space station, and some of the astronauts will transfer to the waiting lander. Finally, the astronauts will descend to the lunar surface. After their sortie on the moon, they’ll return to the orbital station, where the crew will board Orion for the trip home.

Fine-Tuning the Factory: Simulation App Helps Optimize Additive Manufacturing Facility

An example of a part produced through the metal powder bed fusion process.

This sponsored article is brought to you by COMSOL.

History teaches that the Industrial Revolution began in England in the mid-18th century. While that era of sooty foundries and mills is long past, manufacturing remains essential — and challenging. One promising way to meet modern industrial challenges is by using additive manufacturing (AM) processes, such as powder bed fusion and other emerging techniques. To fulfill its promise of rapid, precise, and customizable production, AM demands more than just a retooling of factory equipment; it also calls for new approaches to factory operation and management.
