Credit: NASA While in Milan for international meetings, NASA Administrator Bill Nelson was among the witnesses as Estonia signed the Artemis Accords and became the 45th nation to join the United States and other signatories agreeing to the safe, transparent, and responsible exploration of the Moon, Mars, and beyond.
The signing ceremony took place ahead of Italy hosting the 75th International Astronautical Congress beginning Monday, Oct. 14, where government and space officials from signatory countries will discuss advancing implementation of the Artemis Accords, among other topics.
“We welcome Estonia’s signing of the Artemis Accords, which will open the door for more international collaboration,” said Nelson. “This decision also strengthens our family of nations, united by a common cause, and builds on our commitment to explore space for the benefit of humanity under the sound principles of the accords.”
Erkki Keldo, Estonia’s minister of economy and industry, signed the Artemis Accords. Rahima Kandahari, deputy assistant secretary for the U.S. State Department and Lisa Campbell, CSA (Canadian Space Agency) president, also participated in the event.
“Estonia is well known as the leading country in e-governance, and it is a great honor for us to enter a next level in space exploration, said Keldo. “We are more than interested to share our knowledge with the global space community to make future collaboration in space exploration a success for humankind. I am sure that joining the Artemis Accords will open attractive opportunities to Estonian enterprises too, to share their valuable knowledge and competences.”
In 2020, the United States and seven other nations were the first to sign the Artemis Accords, which identified an early set of principles promoting the beneficial use of space for humanity. The accords are grounded in the Outer Space Treaty and other agreements including the Registration Convention, the Rescue and Return Agreement, as well as best practices and norms of responsible behavior that NASA and its partners have supported, including the public release of scientific data.
The commitments of the Artemis Accords and efforts by the signatories to advance implementation of these principles support the safe and sustainable exploration of space. More countries are expected to sign in the coming weeks and months.

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.

Illustration of logistics elements on the lunar surface. NASA NASA is asking U.S. industry to submit innovative architecture solutions that could help the agency land and move cargo on the lunar surfaced during future Artemis missions. Released in September, the agency’s request for proposal also supports NASA’s broader Moon to Mars Objectives.
Previously, NASA published two white papers outlining lunar logistics and mobility gaps as part of its Moon to Mars architecture development effort that augmented an earlier white paper on logistics considerations. The current ask, Lunar Logistics and Mobility Studies, expects proposing companies to consider these publications, which describe NASA’s future needs for logistics and mobility.
“NASA relies on collaborations from diverse partners to develop its exploration architecture,” said Nujoud Merancy, deputy associate administrator, strategy and architecture in the Exploration Systems Development Mission Directorate at NASA Headquarters in Washington. “Studies like this allow the agency to leverage the incredible expertise in the commercial aerospace community.”
Lunar Logistics Drivers, Needs
Logistics items, including food, water, air, and spare parts, comprise a relatively large portion of the cargo NASA expects to need to move around on the Moon, including at the lunar South Pole where the agency plans to send crew in the future.
The Lunar Logistics Drivers and Needs white paper outlines the importance of accurately predicting logistics resupply needs, as they can heavily influence the overall architecture and design of exploration missions.
As the agency progresses into more complex lunar missions, NASA will require more and more lunar logistics as the agency increases mission frequency and duration. This current proposal seeks industry studies that could help inform NASA’s approach to this growing need.
Lunar Mobility Drivers, Needs
The white paper discusses the transportation of landed cargo and exploration assets from where they are delivered to where they are used, such as to locations with ideal lighting, away from ascent vehicle landing sites, or near other assets. These distances can range from yards to miles away from landing locations, and the ability to move around landing sites easily and quickly are key to exploring the lunar surface efficiently.
NASA’s current planned lunar mobility elements, such as the Lunar Terrain Vehicle and Pressurized Rover, have a capability limit of about 1,760 pounds (800 kilograms) and will primarily be used to transport astronauts around the lunar surface. However, future missions could include a need to move cargo totaling around 4,400 to 13,000 pounds (2,000 to 6,000 kg). To meet this demand, NASA must develop new mobility capabilities with its partners.
Lunar Surface Cargo
The Lunar Surface Cargo white paper characterizes lunar surface cargo delivery needs, compares those needs with current cargo lander capabilities, and outlines considerations for fulfilling this capability gap. While cargo delivery capabilities currently included in the Moon to Mars architecture — like CLPS (Commercial Lunar Payload Services) and human-class delivery landers — can meet near-term needs, there are substantial gaps for future needs.
Access to a diverse fleet of cargo landers would empower a larger lunar exploration footprint. A combination of international partnerships and U.S. industry-provided landers could supply the concepts and capabilities to meet this need. The request for proposals doesn’t explicitly seek new lander concepts but does ask for integrated assessments of logistics that can include transportation elements.
“We’re looking for industry to offer creative insights that can inform our logistics and mobility strategy,” said Brooke Thornton, industry engagement lead for NASA’s Strategy and Architecture Office. “Ultimately, we’re hoping to grow our awareness of the unique capabilities that are or could become a part of the commercial lunar marketplace.”
This is the latest appendix to NASA’s Next Space Technologies for Exploration Partnerships (NextSTEP-2). Solicitations under NextSTEP seek commercial development of capabilities that empower crewed exploration in deep space. NASA published the latest NextSTEP omnibus, NextSTEP-3, on Sept. 27.
