When NASA sends a rover or other piece of technology to the moon, there is no guarantee it will work under lunar gravity—an object that weighs 100 pounds on Earth weighs just 16.5 pounds on the moon. But the space agency now has a way to give lunar technologies a dress rehearsal.
"An extended period of simulated lunar gravity is an important test regime for NASA," said Greg Peters, program manager for NASA's Flight Opportunities program, in a blog post . "It's crucial to reducing risk for innovations that might one day go to the lunar surface."
With a little help from NASA's Flight Opportunities team, Blue Origin upgraded New Shepard's crew capsule. Its reaction control system was modified for the capsule to complete 11 revolutions per minute, simulating gravity one-sixth that of Earth's.
Other mission payloads came from Honeybee Robotics, part of Blue Origin's In-Space Systems business, Draper, Purdue University, and the University of California in Santa Barbara. For example, Honeybee's Honey Bubble Excitation Experiment (H-BEE) will study how bubbles behave in liquids on the moon.
