Astronaut and Artemis II pilot, Victor Glover, maneuvers the latch handle on an Orion test side hatch during performance evaluations at the Lockheed Martin Space campus in Littleton, Colorado.Photo credit: Lockheed Martin Artemis II NASA astronauts Victor Glover, Christina Koch, and Reid Wiseman, and CSA (Canadian Space Agency) astronaut Jeremy Hansen recently traveled to Lockheed Martin Space in Littleton, Colorado, where they practiced opening and closing an Orion crew module side hatch model to help demonstrate its reliability and durability during their 10-day mission around the Moon.
During normal mission operations, the crew will not operate the hatches – the ground systems team at NASA’s Kennedy Space Center in Florida will assist the crew into Orion at the launch pad, then close the hatch behind them prior to liftoff. After splashdown in the Pacific Ocean, recovery teams will open the side hatch and help crew to exit.
Back-up crew members Andre Douglas of NASA and Jenni Gibbons of CSA also trained on hatch operations, which help ensure the crew can safely enter and exit the spacecraft in the event of an emergency. The side hatch is normally opened using a manual gearbox system, but in an emergency, the hatch has release mechanisms containing small pyrotechnic (explosive) devices that release the latch pins on the hatch instantaneously, allowing the hatch to open quickly.
Under NASA’s Artemis campaign, the agency will establish the foundation for long-term scientific exploration at the Moon, land the first woman, first person of color, and its first international partner astronaut on the lunar surface, and prepare for human expeditions to Mars for the benefit of all.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA astronaut Yvonne Cagle and former astronaut Kenneth Cockrell pose with Eli Toribio and Rhydian Daniels at the University of California, San Francisco Bakar Cancer Hospital. Patients gathered to meet the astronauts and learn more about human spaceflight and NASA’s cancer research efforts.NASA/Brandon Torres Navarrete NASA astronauts, scientists, and researchers, and leadership from the University of California, San Francisco (UCSF) met with cancer patients and gathered in a discussion about potential research opportunities and collaborations as part of President Biden and First Lady Jill Biden’s Cancer Moonshot initiative on Oct. 4.
Roundtable discussions centered conversation around the five hazards of human spaceflight: space radiation, isolation and confinement, distance from Earth, gravity, and closed or hostile environments. Many of these hazards have direct correlations to a cancer patient’s lived experience, like the isolation of a hospital room and long-term effects of radiation.
During the visit with patients at the UCSF Benioff Children’s Hospital San Francisco, NASA astronaut Yvonne Cagle and former astronaut Kenneth Cockrell answered questions about spaceflight and life in space.
Patients also received a video message from NASA astronauts Suni Williams and Butch Wilmore from the International Space Station, and met with Vanessa Wyche, director of NASA’s Johnson Space Center in Houston, Eugene Tu, director of NASA’s Ames Research Center in California’s Silicon Valley, and other agency leaders.
Leadership from NASA and the University of California, San Francisco gathered for an informal luncheon before a collaborative roundtable discussion of research opportunities. From left to right, Alan Ashworth, president of the UCSF Helen Diller Family Comprehensive Cancer Center, Eugene Tu, director of NASA’s Ames Research Center in California’s Silicon Valley, David Korsmeyer, deputy director of Ames, Sam Hawgood, chancellor of UCSF, and Vanessa Wyche, director of NASA’s Johnson Space Center in Houston. By connecting the dots between human space research and cancer research, NASA and the University of California hope to open doors to innovative new research opportunities. NASA is working with researchers, institutions, and agencies across the federal government to help cut the nation’s cancer death rate by at least 50% in the next 25 years, a goal of the Cancer Moonshot Initiative.

On flight day 13, Orion reached its maximum distance from Earth during the Artemis I mission when it was 268,563 miles away from our home planet. Orion has now traveled farther than any other spacecraft built for humans.Credit: NASA NASA’s Orion spacecraft is designed to keep astronauts safe in deep space, protecting them from the unforgiving environment far from Earth. During the uncrewed Artemis I mission, researchers from NASA, along with several collaborators, flew payloads onboard Orion to measure potential radiation exposure to astronauts.
Radiation measurements were taken inside Orion by 5,600 passive sensors and 34 active radiation detectors during its 25.5-day mission around the Moon and back, which provided important data on exposure within the Earth’s Van Allen radiation belt. These detailed findings were published in a recent scientific article through a collaborative effort by NASA’s Space Radiation Analysis Group, the DLR (German Space Center), and ESA (European Space Agency). The measurements show that while radiation exposure can vary depending on location within Orion, the spacecraft can protect its crew from potentially hazardous radiation levels during lunar missions.
Space radiation could pose major risks to long-duration human space flights, and the findings from the Artemis I mission represent a crucial step toward future human exploration beyond low Earth orbit, to the Moon, and eventually to Mars.
NASA’s HERA (Hybrid Electronic Radiation Assessor) and Crew Active Dosimeter, which were tested previously on the International Space Station, and ESA’s Active Dosimeter, were among the instruments used to measure radiation inside Orion. HERA’s radiation sensor can warn crew members need to take shelter in the case of a radiation event, such as a solar flare. The Crew Active Dosimeter can collect real-time radiation dose data for astronauts and transmit it back to Earth for monitoring. Radiation measurements were conducted in various areas of the spacecraft, each offering different levels of shielding.

These manikins enabled measurements of radiation doses on various body parts, providing valuable insight into how radiation may affect astronauts traveling to deep space.
Two manikins are installed in the passenger seats inside the Artemis I Orion crew module atop the Space Launch System rocket in High Bay 3 of the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Aug. 8, 2022. As part of the Matroshka AstroRad Radiation Experiment (MARE) investigation, the two female manikins – Helga and Zohar – are equipped with radiation detectors, while Zohar also wears a radiation protection vest, to determine the radiation risk on its way to the Moon.

Researchers found that Orion’s design can protect its crew from potentially hazardous radiation levels during lunar missions. Though the spacecraft’s radiation shielding is effective, the range of exposure can greatly vary based on spacecraft orientation in specific environments. When Orion altered its orientation during an engine burn of the Interim Cryogenic Propulsion Stage, radiation levels dropped nearly in half due to the highly directional nature of the radiation in the Van Allen belt.
“These radiation measurements show that we have an effective strategy for managing radiation risks in the Orion spacecraft. However, key challenges remain, especially for long-duration spaceflights and the protection of astronauts on spacewalks,” said Stuart George, NASA’s lead author on the paper.
NASA’s long-term efforts and research in mitigating space radiation risks are ongoing, as radiation measurements on future missions will depend heavily on spacecraft shielding, trajectory, and solar activity. The same radiation measurement hardware flown on Artemis I will support the first crewed Artemis mission around the Moon, Artemis II, to better understand the radiation exposure seen inside Orion and ensure astronaut safety to the Moon and beyond.
