NASA’s Artemis I Mission Sees Successful Completion

Reading time ( words)

NASA’s Artemis I mission came to a successful conclusion with the splashdown and recovery of the Orion spacecraft. This mission was an uncrewed, integrated flight test of the hardware and technology that will take humans back to the Moon for the first time in more than five decades.

The Space Launch System (SLS) rocket, Orion spacecraft and Exploration Ground Systems (EGS) at NASA’s Kennedy Space Center in Florida performed flawlessly during the Artemis I launch on Nov. 16. During a nearly 26-day mission, Orion traveled more than 1.4 million miles on a path that took it around and beyond the Moon before returning to Earth. The flight testing and data from the mission inform future Artemis missions.

As the foundational elements of NASA’s deep space exploration architecture, Orion is the safest human spacecraft ever developed, and the launch and ground systems were designed to deliver greater mass and volume with more Earth-orbit departure energy than any existing system. With planned upgrades, the architectures will be able to support future missions to destinations beyond the Moon, including Mars.

The next step in NASA’s Artemis program is launching the first crewed flight to the Moon and back on the Artemis II mission. All elements for that mission are deep into assembly. Work on Artemis III, which aims to put the first woman and person of color on the Moon, is well under way with many of the systems, such as the propulsion for SLS and Orion, nearly complete.

The Artemis program constitutes an important national capability that leverages more than 3,800 suppliers and 60,000 workers across all 50 states. The program sustains an essential industrial base of large, mid-size and small companies that provide high-tech, professional jobs across the country.

Industry partners – Aerojet Rocketdyne, Boeing, Jacobs, Lockheed Martin and Northrop Grumman – applaud NASA and their suppliers across the nation for the successful once-in-a-generation accomplishment of launching SLS and Orion as humanity looks toward exploring deep space as humans never have before.

  • Aerojet Rocketdyne provided the 39 propulsive elements to the mission, including the RS-25 and RL10 engines affixed to the core and upper stage that carried the SLS and Orion into orbit, as well as the jettison motor for the Orion spacecraft’s Launch Abort System (LAS).
  • Boeing is the prime contractor for the design, development, test and production of the launch vehicle core stage and upper stages as well as the development of the flight avionics suite.
  • Jacobs was responsible for the rocket’s final assembly, integration, testing, launch and recovery operations support, including development of the Artemis ground and launch control software used in the NASA Launch Control Center at Kennedy Space Center.
  • Lockheed Martin is the prime contractor for the Orion spacecraft, including the LAS, crew module and crew module adaptor.
  • Northrop Grumman contributed the twin solid rocket boosters that supplied more than 75% of the thrust at launch, as well as the abort motor and attitude control motor for the LAS.

DARPA has selected three industry corporations for the Underexplored Systems for Utility-Scale Quantum Computing (US2QC) program. US2QC seeks to determine whether an underexplored approach to quantum computing is capable of achieving utility-scale operation – meaning its computational value exceeds its cost – much faster than conventional predictions.

Solder Joint Reliability With IMS Materials

Pete Starkey had the opportunity to attend a technical webinar on thermal management hosted by American Standard Circuits and featuring Ventec International Group’s range of insulated metal substrate materials. The webinar was moderated by Anaya Vardya, president and CEO of American Standard Circuits, and the speakers were Ventec’s Global Head of IMS Technology Chris Hanson and Technical Manager Denis McCarthy. The group identified factors that influence thermo-mechanical robustness and provided a logical solution.
