Preparations for Next Moonwalk Simulations Underway (and Underwater)
Test flights help airplane and drone manufacturers identify which parts of the aircraft are creating the most noise. Using hundreds of wired microphones makes it an expensive and time-consuming process to improve the design to meet noise requirements. Credit: NASA Airplane manufacturers running noise tests on new aircraft now have a much cheaper option than traditional wired microphone arrays. It’s also sensitive enough to help farmers with pest problems. A commercial wireless microphone array recently created with help from NASA can locate crop-threatening insects by listening for the sounds they make in fields.
Since releasing its first commercial product in 2017, a sensor for wind tunnel testing developed with extensive help from NASA (Spinoff 2020), Interdisciplinary Consulting Corporation (IC2) has doubled its staff and moved to a larger lab and office space to produce its new WirelessArray product. Interested in making its own flight tests more affordable, NASA’s Langley Research Center in Hampton, Virginia, supported this project with Small Business Innovation Research contracts and expert consulting.
Airplanes go through noise testing and require certification that they don’t exceed the noise level set for their body type by the Federal Aviation Administration. When an airplane flies directly overhead, the array collects noise data to build a two-dimensional map of the sound pressure and its source. A custom software package translates that information for the end user.
For previous NASA noise testing, multiple semi-trucks hauled all the sensors, wires, power generators, racks of servers, and other equipment required for one flight test. The setup and teardown took six people three days. By contrast, two people can pack the WirelessArray into a minivan and set it up in a day.
IC2 is working with an entomologist to use acoustic data to listen for high-frequency insect sounds in agricultural settings. Discovering where insects feed on crops will make it possible for farmers to intervene before they do too much damage while limiting pesticide use to those areas. Whether it’s helping planes in the sky meet noise requirements or keeping harmful insects away from crops, NASA technology is finding sound-based solutions for the benefit of all.

SpaceX A SpaceX Falcon 9 rocket with the company’s Dragon spacecraft on top is seen during sunrise on the launch pad at NASA’s Kennedy Space Center in Florida on Tuesday, March 11, 2025, ahead of the agency’s SpaceX Crew-10 launch.
NASA astronauts Anne McClain, Nichole Ayers, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov will lift off from Launch Complex 39A at NASA Kennedy. Once aboard the International Space Station, the Crew-10 members will conduct new scientific research to prepare for human exploration beyond low Earth orbit and benefit humanity on Earth. The crew is scheduled to conduct material flammability tests for future spacecraft designs, engage with students via ham radio and use its existing hardware to test a backup lunar navigation solution, and participate in an integrated study to better understand physiological and psychological changes to the human body to provide valuable insights for future deep space missions.
Watch the launch live on NASA+. Coverage begins at 3:45 p.m. EDT on March 12, 2025, with launch scheduled for 7:48 p.m. EDT.

Official portrait of NASA astronaut Jonny Kim, who will serve as a flight engineer during Expedition 73. Credit: NASA NASA will provide interview opportunities with astronaut Jonny Kim beginning at 9 a.m. EDT, Tuesday, March 18, to highlight his upcoming mission to the International Space Station in April.
The virtual interviews from Star City, Russia, will stream live on NASA+. Learn how to watch NASA content through a variety of platforms, including social media.
Media interested in participating must contact the newsroom at NASA’s Johnson Space Center in Houston no later than 5 p.m., Monday, March 17, at 281-483-5111 or jsccommu@mail.nasa.gov. A copy of NASA’s media accreditation policy is online.
Kim will launch on Tuesday, April 8, aboard the Roscosmos Soyuz MS-27 spacecraft, accompanied by Roscosmos cosmonauts Sergey Ryzhikov and Alexey Zubritsky. The trio will spend approximately eight months aboard the orbital laboratory before returning to Earth in the fall 2025. During his time in orbit, Kim will conduct scientific investigations and technology demonstrations to help prepare the crew for future space missions and provide benefits to people on Earth.
Kim is making his first spaceflight after selection as part of the 2017 NASA astronaut class. A native of Los Angeles, he is a U.S. Navy lieutenant commander and dual designated naval aviator and flight surgeon. Kim also served as an enlisted Navy SEAL. He holds a bachelor’s degree in Mathematics from the University of San Diego and a medical degree from Harvard Medical School in Boston. He completed his internship with the Harvard Affiliated Emergency Medicine Residency at Massachusetts General Hospital and Brigham and Women’s Hospital. After completing initial astronaut candidate training, Kim supported mission and crew operations in various roles, including the Expedition 65 lead operations officer, T-38 operations liaison, and space station capcom chief engineer.

For more than two decades, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge, and making research breakthroughs that are not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA is able to focus more of its resources on deep space missions to the Moon and Mars.
