NASA Associate Administrator Jim Free welcomed the Republic of Cyprus as the latest nation to commit to the responsible use of space for humanity on Wednesday, marking 46 signatories to date.
“We applaud Cyprus’ commitment to the Artemis Accords, which will enhance the country’s engagement with NASA and the international community,” said Free, who participated virtually. “By joining 45 other country signatories in this effort, Cyprus will help play a role in implementing the accords and exploration that is open, responsible, transparent, and peaceful for the benefit of all.”
Nicodemos Damianou, Cyprus’ deputy minister of research, innovation, and digital policy, signed the Artemis Accords during a ceremony in Nicosia, Cyprus. James O’Brian, assistant secretary for European and Eurasian Affairs for the U.S. Department of State, also attended the event.
“Today marks a significant milestone for Cyprus as we officially sign the Artemis Accords,” said Damianou. “As we embark on this exciting journey, we reaffirm our commitment to a safe and responsible space exploration, as well as our strong belief in the importance of international cooperation in ensuring space is utilized to the benefit of all humanity. Cyprus, an European Union member state, is capitalizing on its geostrategic location between three continents, and aspires to play an integral role in the international space community.”
The signing with Cyprus comes on the heels of an Artemis Accords meeting in Milan earlier this month with dozens of signatory countries, including the United States.
In 2020, NASA, in coordination with the U.S. Department of State and seven other initial signatory nations, established the Artemis Accords, which identified an early set of principles promoting the beneficial use of space for humanity. The Artemis 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 days and weeks ahead.

Europa Trek: NASA Offers a New Guided Tour of Jupiter’s Ocean Moon
NASA’s Europa Clipper mission is on its way to explore a moon of Jupiter that researchers believe may be one of the best places in the Solar System to search for life beyond Earth. While the spacecraft makes its more-than-five year journey to Europa, scientists, students, teachers, and the public can tour and explore the landforms of Europa with newly-released enhancements to NASA’s Europa Trek web portal.
One of the largest of Jupiter’s nearly 100 recognized moons, Europa is covered with a global ice cap. But beneath that crust of ice, researchers have found an ocean of liquid water, estimated to have about twice the volume of all of Earth’s oceans combined. This vast amount of liquid water is of particular interest to astrobiologists, scientists studying the origin, evolution, and distribution of life in the Universe. Though Europa’s ocean remains hidden beneath its global crust of ice, we can get important clues about its nature by studying the remarkable landforms of Europa’s icy surface.
To accompany the launch of Europa Clipper, NASA’s Solar System Treks Project released exciting new enhancements to its online Europa Trek portal on September 30, 2024. The new additions to Europa Trek allow users to interactively fly over and explore high-resolution imagery of Europa’s surface from the Voyager, Galileo, and Juno missions. Users can also take a new guided tour of Europa’s amazing landforms, with commentary developed by a collaboration between NASA’s Astrobiology Science Communication Guild and NASA’s Solar System Exploration Research Virtual Institute. The tour and its commentary introduce virtual explorers to the geology and possible biological significance of the diverse features of Europa’s surface.
“This is really fun. It’s cool how you can zoom into the high resolution data. I’ll spread the word about using this!” – Bob Pappalardo, Europa Clipper Project Scientist
The new tour and capabilities of Europa Trek were featured at the Europa Clipper public launch program at the Kennedy Space Center Visitor Center on October 6,2024, in advance of the October 14 launch of the mission. As part of the public program conducted by NASA’s Planetary Mission Program Office, the Europa Trek exhibit allowed hundreds of visitors to try their hands at flying over Europa and visualizing its exotic terrain.
NASA’s Solar System Treks is an infrastructure project within NASA’s Science Activation Team. Their online portals are used for mission planning, planetary science research, and Science, Technology, Engineering, & Mathematics (STEM) education. NASA’s Astrobiology Science Communication Guild is an international, community-based network of astrobiologists who engage in science communication with diverse audiences and learners. Watch for future collaborations between Solar System Treks and the Astrobiology Science Communication Guild at more locations across the Solar System!

A test image of Earth taken by NASA’s Pathfinder Technology Demonstrator-4’s onboard camera. The camera will capture images of the Lightweight Integrated Solar Array and anTenna upon deployment.NASA NASA recently evaluated initial flight data and imagery from Pathfinder Technology Demonstrator-4 (PTD-4), confirming proper checkout of the spacecraft’s systems including its on-board electronics as well as the payload’s support systems such as the small onboard camera. Shown above is a test image of Earth taken by the payload camera, shortly after PTD-4 reached orbit. This camera will continue photographing the technology demonstration during the mission.
Payload operations are now underway for the primary objective of the PTD-4 mission – the demonstration of a new power and communications technology for future spacecraft. The payload, a deployable solar array with an integrated antenna called the Lightweight Integrated Solar Array and anTenna, or LISA-T, has initiated deployment of its central boom structure. The boom supports four solar power and communication arrays, also called petals. Releasing the central boom pushes the still-stowed petals nearly three feet (one meter) away from the spacecraft bus. The mission team currently is working through an initial challenge to get LISA-T’s central boom to fully extend before unfolding the petals and beginning its power generation and communication operations.
Small spacecraft on deep space missions require more electrical power than what is currently offered by existing technology. The four-petal solar array of LISA-T is a thin-film solar array that offers lower mass, lower stowed volume, and three times more power per mass and volume allocation than current solar arrays. The in-orbit technology demonstration includes deployment, operation, and environmental survivability of the thin-film solar array.
“The LISA-T experiment is an opportunity for NASA and the small spacecraft community to advance the packaging, deployment, and operation of thin-film, fully flexible solar and antenna arrays in space. The thin-film arrays will vastly improve power generation and communication capabilities throughout many different mission applications,” said Dr. John Carr, deputy center chief technologist at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “These capabilities are critical for achieving higher value science alongside the exploration of deep space with small spacecraft.”
The Pathfinder Technology Demonstration series of missions leverages a commercial platform which serves to test innovative technologies to increase the capability of small spacecraft. Deploying LISA-T’s thin solar array in the harsh environment of space presents inherent challenges such as deploying large highly flexible non-metallic structures with high area to mass ratios. Performing experiments such as LISA-T on a smaller, lower-cost spacecraft allows NASA the opportunity to take manageable risk with high probability of great return. The LISA-T experiment aims to enable future deep space missions with the ability to acquire and communicate data through improved power generation and communication capabilities on the same integrated array.
The PTD-4 small spacecraft is hosting the in-orbit technology demonstration called LISA-T. The PTD-4 spacecraft deployed into low Earth orbit from SpaceX’s Transporter-11 rocket which launched from Space Launch Complex 4E at Vandenberg Space Force Base in California on Aug. 16. NASA’s Marshall Space Flight Center in Huntsville, Alabama designed and built the LISA-T technology as well as LISA-T’s supporting avionics system. NASA’s Small Spacecraft Technology program, based at NASA’s Ames Research Center in California’s Silicon Valley and led by the agency’s Space Technology Mission Directorate, funds and manages the PTD-4 mission as well as the overall Pathfinder Technology Demonstration mission series. Terran Orbital Corporation of Irvine, California, developed and built the PTD-4 spacecraft bus, named Triumph.
Learn more about NASA’s LISA-T technology:
NASA teams are testing a key technology demonstration known as LISA-T, short for the Lightweight Integrated Solar Array and anTenna. It’s a super compact, stowable, thin-film solar array that when fully deployed in space, offers both a power generation and communication capability for small spacecraft. LISA-T’s orbital flight test is part of the Pathfinder Technology Demonstrator series of missions. To travel farther into deep space, small spacecraft require more electrical power than what is currently available through existing technology. LISA-T aims to answer that demand and would offer small spacecraft access to power without compromising mass or volume. Watch this video to learn more about the spacecraft, its deployment, and the possibilities from John Carr, deputy center chief technologist at NASA’s Marshall Space Flight Center in Huntsville, Alabama.
