NASA JPL Testing Readies Voyager Technologies Lander for Moon Mission - NASA

4 min read NASA JPL Testing Readies Voyager Technologies Lander for Moon Mission Jet Propulsion Laboratory Oct 13, 2026 Article Engineers and technicians use a crane to position Voyager Technologies’ Griffin-1 lunar lander within the 25-Foot Space Simulator at NASA’s Jet Propulsion Laboratory on Aug. 31. The spacecraft recently completed a series of rigorous environmental tests at JPL ahead of launch to the Moon later this year. NASA/JPL-Caltech The testing team moves Voyager Technologies’ Griffin-1 through a hallway to the 25-Foot Space Simulator at JPL. The corridor features photos of the historic spacecraft that have been tested in the facility since the 1960s, from the Ranger program to NASA’s Europa Clipper. NASA/JPL-Caltech A commercial lander that will be at the forefront of NASA’s efforts to establish a Moon Base, humanity’s first lunar outpost, has passed a series of critical tests at the agency’s Jet Propulsion Laboratory in Southern California. The tests simulated the extreme temperatures and vacuum of space, as well as the intense shaking and ear-splitting roar of launch. Results show that Voyager Technologies’ Griffin Mission One (Griffin-1) spacecraft is ready to survive the rigors of space exploration. As part of NASA’s CLPS (Commercial Lunar Payload Services) initiative within the Moon Base Program, Griffin-1 is expected to launch later this year aboard a SpaceX Falcon Heavy rocket. It will deliver more than 1,100 pounds (455 kilograms) of cargo to Nobile Crater near the lunar South Pole, which categorizes it as an infrastructure-class lander. Griffin-1 will carry 10 science and technology demonstrations from six countries, including the largest commercial payload ever delivered to the Moon, Astrolab’s FLIP (FLEX Lunar Innovation Platform) rover. “NASA JPL’s Environmental Test Laboratory has been putting robotic explorers to the test since the Ranger program gave us NASA’s first up-close views of the Moon’s surface in the mid-1960s. We’re proud to provide our expertise and facilities to support this new phase of commercial lunar exploration,” said Charles Whetsel, manager, Exploration Systems Development Office at JPL. Long foam spikes that absorb sound waves and electromagnetic waves cover the walls of a specialized anechoic chamber at JPL where Voyager Technologies’ Griffin-1 underwent electromagnetic interference and electromagnetic compatibility testing. NASA/JPL-Caltech Griffin-1’s testing journey Testing began in July after the 2,789-pound (1,265-kilogram) spacecraft took a cross-country road trip from Voyager Lunar Systems’ manufacturing facilities in Pittsburgh to JPL in the San Gabriel Mountain foothills. Engineers spun the spacecraft on a special table to measure its mass properties, a test that enables them to look for any unexpected wobbles as they assess how the lander will move through space. Data gathered in mass properties testing is key to understanding the spacecraft’s readiness for navigation in flight and landing on the lunar surface. To make sure signals from the spacecraft’s electronic components don’t interfere with one another, Griffin-1 underwent electromagnetic interference and electromagnetic compatibility testing inside what’s called an anechoic chamber, in which long foam spikes line the walls to absorb sound and electromagnetic waves. During vibration testing, hundreds of sensors monitored Griffin-1 as a “shaker table” rattled it in three directions, with increasingly intense force, to simulate the ride out of Earth’s atmosphere on a massive rocket. To mimic the roar of launch, giant horns, powered by compressed nitrogen gas, blasted the spacecraft with up to 153 decibels inside a sealed acoustic chamber. Environmental testing took place in several clean-room facilities at JPL, culminating in the 25-Foot Space Simulator , a thermal vacuum chamber listed on the National Register of Historic Places for its role in supporting historic missions like those of the Ranger , Surveyor , Mariner , and Voyager programs. Dozens of other missions (along with plenty of upgrades to the testing facility) have followed over the decades, including the Perseverance Mars rover and Europa Clipper . Voyager Technologies’ Griffin-1 lunar lander spins on a special table in a test to measure its mass properties, which enables engineers to look for any unexpected wobbles as they assess how the vehicle will move through space. The test took place in JPL’s Environmental Test Laboratory on July 20. NASA/JPL-Caltech Microphones are arrayed around Griffin-1 on Aug. 12 during acoustic testing that mimics the intense roar of launch. Giant horns powered by compressed gaseous nitrogen blast the spacecraft with up to 153 decibels inside a sealed acoustic chamber at JPL. NASA/JPL-Caltech Beneath the thermal vacuum chamber’s soaring 85-foot (26-meter) ceiling, for about two weeks, Griffin-1 alternately baked at up to 167 degrees Fahrenheit (75 degrees Celsius) and froze at temperatures as low as minus 148 F (minus 100 C). This testing simulates the temperature extremes the lander will experience during its journey through the vacuum of space and its operations on the lunar surface. “Griffin-1 is being built for a historic purpose: to deliver the infrastructure and capabilities to the Moon. Seeing the spacecraft complete this demanding environmental testing is a major milestone because it demonstrates that Griffin-1 is ready for the extreme journey ahead: launch, through deep space, to the lunar South Pole,” said John Thornton, executive vice president, Voyager. “This spacecraft represents a new era of commercial lunar exploration, where missions like Griffin-1 are laying the groundwork for the Moon Base and helping turn sustained lunar exploration from a vision into a reality.” After proving its mettle at JPL, Griffin-1 has returned to Voyager Lunar Systems’ facility for final assembly.
