NASA/Steven Seipel On Sept. 2, 2022, NASA astronauts Anil Menon (left), Deniz Burnham (center), and Marcos Berrios (right) posed for a photograph in front of NASA’s Artemis I SLS (Space Launch System) and Orion spacecraft at the agency’s Kennedy Space Center in Florida.
Burnham began her career as an intern at NASA’s Ames Research Center. She earned a bachelor’s degree in chemical engineering from the University of California, San Diego, and a master’s degree in mechanical engineering from the University of Southern California in Los Angeles.
Burnham reported for duty in January 2022 to complete two years of initial astronaut training as a NASA astronaut candidate. Burnham, Menon, and Berrios astronaut candidates graduated in a ceremony on March 5, 2024. The graduates may be assigned to missions destined for the International Space Station, future commercial space stations, and Artemis campaign missions to the Moon in preparation for Mars.
Applications to become a NASA intern are currently open. Apply for Spring 2025 internships by Aug. 23, 2024.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The LZR Racer reduces skin friction drag by covering more skin than traditional swimsuits. Multiple pieces of the water-resistant and extremely lightweight LZR Pulse fabric connect at ultrasonically welded seams and incorporate extremely low-profile zippers to keep viscous drag to a minimum.Credit: SpeedoUSA A supersonic airplane and a competitive swimmer have much more in common than people might realize; both have to contend with the slowing influence of drag. NASA’s Aeronautics Research Mission Directorate focuses primarily on improving flight efficiency and fluid dynamics, especially the forces of pressure and drag, which are the same for bodies moving through air as for bodies moving through water. Shortly after the 2004 Olympics, Los Angeles-based SpeedoUSA, also known as Speedo, asked NASA’s Langley Research Center to help design a swimsuit with reduced surface drag. The manufacturer sought a partnership with NASA because of the agency’s expertise in fluid dynamics.
In competitive swimming, where every hundredth of a second counts, achieving the best possible drag reduction is crucially important. Researchers at NASA began flat plate testing of fabrics, using a small wind tunnel developed for earlier research on low-speed viscous drag reduction and collaborated over the next few years with Speedo to design the LZR Racer swimsuit.

Wind tunnel testing at Langley enabled Speedo’s LZR Racer to achieve its excellent underwater performance.NASA/David C. Bowman. NASA and Speedo performed tests on traditionally sewn seams, ultrasonically welded seams, and the fabric alone, which gave Speedo a baseline for reducing drag caused by seams and helped identify problem areas. NASA wind tunnel results helped Speedo create a bonding system that eliminates seams and reduces drag. The results also showed that a low-profile zipper ultrasonically bonded into the fabric inside the suit generated eight percent less drag in wind tunnel tests than a standard zipper. Low-profile seams and zippers were a crucial component in the LZR Racer, because the suit consists of multiple connecting fabric pieces—instead of just a few sewn pieces such as found in traditional suits—that provide extra compression for maximum efficiency.
In March 2008, the LZR Racer made its mark on the world of competitive swimming. Athletes donning this innovative swimsuit shattered 13 world records, a testament to the power of collaboration between NASA and Speedo. While the original LZR Racer is no longer used in competition because of the advantage it gave wearers, its legacy lives on in today’s swimsuits approved by World Aquatics, the governing body for international competitive swimming.

NASA Astronaut Eileen Collins, STS-93 commander, looks through a checklist on the space shuttle Columbia’s middeck in this July 1999 image. Collins was the first female shuttle commander.
Collins graduated in 1979 from Air Force Undergraduate Pilot Training at Vance AFB, Oklahoma, where she was a T-38 instructor pilot until 1982. She continued her career as an instructor pilot of different aircraft until 1989. She was selected for the astronaut program while attending the Air Force Test Pilot School at Edwards AFB, California, which she graduated from in 1990. Collins became an astronaut in 1991 and over the course of four spaceflights, logged over 872 hours in space. She retired from NASA in May 2006.
