Geared toward improving spacecraft navigation, the technology demonstration operated far longer than planned and broke the stability record for atomic clocks in space.
PASADENA, Calif. (NASA PR) — For more than two years, NASA’s Deep Space Atomic Clock has been pushing the timekeeping frontiers in space. On Sept. 18, 2021, its mission came to a successful end.
The instrument is hosted on General Atomics’ Orbital Test Bed spacecraft that was launched aboard the Department of Defense Space Test Program 2 mission June 25, 2019. Its goal: to test the feasibility of using an onboard atomic clock to improve spacecraft navigation in deep space.
Designed to improve navigation for robotic explorers and the operation of GPS satellites, the technology demonstration reports a significant milestone.
PASADENA, Calif. (NASA PR) — Spacecraft that venture beyond our Moon rely on communication with ground stations on Earth to figure out where they are and where they’re going. NASA’s Deep Space Atomic Clock is working toward giving those far-flung explorers more autonomy when navigating. In a new paper published today in the journal Nature, the mission reports progress in their work to improve the ability of space-based atomic clocks to measure time consistently over long periods.
WASHINGTON (NASA PR) — In 2020, NASA made significant progress on America’s Moon to Mars exploration strategy, met mission objectives for the Artemis program, achieved significant scientific advancements to benefit humanity, and returned human spaceflight capabilities to the United States, all while agency teams acted quickly to assist the national COVID-19 response.
SAN DIEGO, CA, (Oct. 6, 2020) — General Atomics Electromagnetic Systems (GA-EMS) announced today that it has received a contract extension for a second year of operations of their Orbital Test Bed (OTB) spacecraft supporting the National Aeronautics and Space Administration (NASA) Jet Propulsion Laboratory (JPL) Deep Space Atomic Clock (DSAC) mission. GA-EMS will continue to provide operations support services from GA-EMS’ spacecraft development and mission operations facilities in Colorado through August 2021.
SAN DIEGO, CA, 26 August 2019 – General Atomics Electromagnetic Systems (GA-EMS) announced today that commissioning of NASA’s Deep Space Atomic Clock (DSAC), the primary hosted payload on-board the Orbital Test Bed (OTB) satellite, is now underway. GA-EMS’ OTB was successfully launched at 2:30 a.m. EDT on June 25, 2019 on board the SpaceX Falcon Heavy rocket.
PASADENA, Calif. (NASA PR) — An atomic clock that could pave the way for autonomous deep space travel was successfully activated last week and is ready to begin its year-long tech demo, the mission team confirmed on Friday, Aug. 23, 2019. Launched in June, NASA’s Deep Space Atomic Clock is a critical step toward enabling spacecraft to safely navigate themselves in deep space rather than rely on the time-consuming process of receiving directions from Earth.
SAN DIEGO, CA (General Atomics PR) – General Atomics Electromagnetic Systems (GA-EMS) announced today that its Orbital Test Bed (OTB) satellite was successfully launched on-board the SpaceX Falcon Heavy rocket from Cape Canaveral. OTB was then successfully deployed into orbit after launch, and communication was established between the spacecraft and ground operations to begin satellite commissioning and operations.
KENNEDY SPACE CENTER, Fla. (NASA PR) — NASA technology demonstrations, which one day could help the agency get astronauts to Mars, and science missions, which will look at the space environment around Earth and how it affects us, have launched into space on a Falcon Heavy rocket.
The NASA missions lifted off at 2:30 a.m. EDT Tuesday from NASA’s Kennedy Space Center in Florida, as part of the Department of Defense’s Space Test Program-2 (STP-2) launch.
HAWTHORNE, Calif. (SpaceX PR) — The Department of Defense (DoD) Space Test Program-2 (STP-2) mission, managed by the U.S. Air Force Space and Missile Systems Center (SMC), is targeting launch on June 24, 2019, with the launch window opening at 11:30 p.m. ET. Lifting off from Launch Complex 39A at the Kennedy Space Center in Florida, this mission will deliver 24 satellites to space on the DoD’s first ever SpaceX Falcon Heavy launch vehicle.
The STP-2 mission will be among the most challenging launches in SpaceX history with four separate upper-stage engine burns, three separate deployment orbits, a final propulsive passivation maneuver and a total mission duration of over six hours. In addition, the U.S. Air Force plans to reuse side boosters from the Arabsat-6A Falcon Heavy launch, recovered after a return to launch site landing, making it the first reused Falcon Heavy ever flown for the U.S. Air Force.

PASADENA, Calif. (NASA/JPL-Caltech PR) — NASA is sending a new technology to space in late June that will change the way we navigate our spacecraft — even how we send astronauts to Mars and beyond. Built by NASA’s Jet Propulsion Laboratory in Pasadena, California, the Deep Space Atomic Clock is a technology demonstration that will help spacecraft navigate autonomously through deep space. No larger than a toaster oven, the instrument will be tested in Earth orbit for one year, with the goal of being ready for future missions to other worlds.
WASHINGTON (NASA PR) — A new kind of atomic clock, non-toxic propellant system and missions to characterize how space weather interferes with satellites and communication transmissions are one step closer to liftoff. With the second-ever SpaceX Falcon Heavy launch complete, these NASA technologies await the powerful rocket’s next flight.
PASADENA, Calif. (NASA PR) — In deep space, accurate timekeeping is vital to navigation, but not all spacecraft have precise timepieces aboard. For 20 years, NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, has been perfecting a clock. It’s not a wristwatch; not something available in a store. It’s the Deep Space Atomic Clock (DSAC), an instrument being built for deep space exploration.
ENGLEWOOD, Colo. (NASA PR) — No one keeps time quite like NASA.
Last month, the space agency’s next-generation atomic clock was joined to the spacecraft that will take it into orbit in late 2017.
That instrument, the Deep Space Atomic Clock was developed by NASA’s Jet Propulsion Laboratory in Pasadena, California. On Feb. 17, JPL engineers monitored integration of the clock on to the Surrey Orbital Test Bed spacecraft at Surrey Satellite Technology in Englewood, Colorado.
WASHINGTON (NASA PR) — NASA’s Space Technology Mission Directorate (STMD) is dedicated to pushing the technological envelope, taking on challenges not only to further space agency missions near Earth, but also to sustain future deep space exploration activities.
“In 2016, we completed several major program milestones,” explains Steve Jurczyk, NASA associate administrator for STMD.
WASHINGTON (NASA PR) — NASA’s Space Technology Mission Directorate (STMD) checked off a number of key accomplishments in 2015. These advancements pushed the technological envelope, not only for use near Earth, but also to support future deep-space exploration missions.
“In 2015 we have made significant progress with several of our larger technology demonstration initiatives,” explains Steve Jurczyk, NASA associate administrator for STMD.
