NASA’s collaboration with the international satellite-aided search and rescue effort known as Cospas-Sarsat has enabled the development of multiple emergency location beacons for explorers on land, sea, and air.
Of the 407 lives saved in 2024 through search and rescue efforts in the United States, NOAA (National Oceanic and Atmospheric Administration) reports that 52 rescues were the result of activated personal locator beacons, 314 from emergency position-indicating radio beacons, and 41 from emergency locator transmitters. Since 1982, more than 50,000 lives have been saved across the world.
Using GPS satellites, these beacons transmit their location to the Cospas-Sarsat network once activated. The beacons then provide the activation coordinates to the network, allowing first responders to rescue lost or distressed explorers.

URT-11 is the eleventh in a series of Artemis recovery tests, and the first time NASA and its partners put their Artemis II recovery procedures to the test with the astronauts.NASA/Kenny Allen The Search and Rescue Office, part of NASA’s SCaN (Space Communications and Navigation) Program, has assisted in search and rescue services since its formation in 1979 Now, the office is building on their long legacy of Earth-based beacon development to support crewed missions to space.
The beacons also are used for emergency location, if needed, as part of NASA’s crew launches to and from the International Space Station, and will support NASA’s Artemis campaign crew recovery preparations during future missions returning from deep space. Systems being tested, like the ANGEL (Advanced Next-Generation Emergency Locator) beacon, are benefitting life on Earth and missions to the Moon and Mars. Most recently, NASA partnered with the Department of Defense to practice Artemis II recovery procedures – including ANGEL beacon activation – during URT-11 (Underway Recovery Test 11).
Miniaturized Advanced Next-Generation Emergency Locator (ANGEL) beacons will be attached to the astronauts’ life preserver units. When astronauts Reid Wiseman, Victor Glover, Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hanse splash back down to Earth — or in the unlikely event of a launch abort scenario — these beacons will allow them to be found if they need to egress from the Orion capsule.NASA The SCaN program at NASA Headquarters in Washington provides strategic oversight to the Search and Rescue office. NOAA manages the U.S. network region for Cospas-Sarsat, which relies on flight and ground technologies originally developed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. U.S. region rescue efforts are led by the U.S. Coast Guard, U.S. Air Force, and many other local rescue authorities.

NASA’s Ames Research Center in Silicon Valley invites media to learn more about Distributed Spacecraft Autonomy (DSA), a technology that allows individual spacecraft to make independent decisions while collaborating with each other to achieve common goals – without human input. The DSA team achieved multiple firsts during tests of such swarm technology as part of the agency’s project.
DSA develops software tools critical for future autonomous, distributed, and intelligent spacecraft that will need to interact with each other to achieve complex mission objectives. Testing onboard the agency’s Starling mission resulted in accomplishments including the first fully distributed autonomous operation of multiple spacecraft, the first use of space-to-space communications to autonomously share status information between multiple spacecraft, and more.
DSA’s accomplishments mark a significant milestone in advancing autonomous systems that will make new types of science and exploration possible.
Caleb Adams, DSA project manager, is available for interview on Wednesday, Feb. 5 and Thursday, Feb. 6. To request an interview, media can contact the Ames Office of Communications by email at arc-dl-newsroom@nasa.gov or by phone at 650-604-4789.

During the Artemis II mission to the Moon, NASA astronauts Reid Wiseman and Victor Glover will take control and manually fly Orion for the first time, evaluating the handling qualities of the spacecraft during a key test called the proximity operations demonstration. This is how to fly Orion.
On NASA’s Artemis II test flight, the first crewed mission under the agency’s Artemis campaign, astronauts will take the controls of the Orion spacecraft and periodically fly it manually during the flight around the Moon and back. The mission provides the first opportunity to ensure the spacecraft operates as designed with humans aboard, ahead of future Artemis missions to the Moon’s surface.
The first key piloting test, called the proximity operations demonstration, will take place after the four crew members — NASA’s Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen — are safely in space, about three hours into the mission. To evaluate the spacecraft’s manual handling qualities, the crew will pilot Orion to approach and back away from the detached upper stage of the SLS (Space Launch System) rocket.
Crew members participating in the demonstration will use two different controllers, called rotational and translational hand controllers, to steer the spacecraft. Three display screens provide the astronauts with data, and another device, called the cursor control device, allows the crew to interact with the displays.
Astronauts will use the rotational hand controller (RHC), gripped in the right hand, to rotate the spacecraft. It controls Orion’s attitude, or the direction the spacecraft is pointing. If the crew wants to point Orion’s nose left, the RHC is twisted left – for nose right, they will twist the RHC right. Similarly, the RHC can control the nose to pitch up or down or roll right or left. “On Artemis II, most of the time the spacecraft will fly autonomously, but having humans aboard is a chance to help with future mission success,” said Reid Wiseman. “If something goes wrong, a crewmember can jump on the controls and help fix the problem. One of our big goals is to check out this spacecraft and have it completely ready for our friends on Artemis III.”
The commander and pilot seats are each equipped with a rotational hand controller (RHC), gripped in the right hand, to rotate the spacecraft. It controls Orion’s attitude, or the direction the spacecraft is pointing. If the crew wants to point Orion’s nose left, the RHC is twisted left — for nose right, they will twist the RHC right. Similarly, the RHC can control the nose to pitch up or down or roll right or left.
The translational hand controller (THC), located to the right or left of the display screens, will move Orion from one point to another. To move the spacecraft forward, the crew pushes the controller straight in — to back up, they will pull the controller out. And similarly, the controller can be pushed up or down and left or right to move in those directions.
When the crew uses one of the controllers, their command is detected by Orion’s flight software, run by the spacecraft’s guidance, navigation, and control system. The flight software was designed, developed, and tested by Orion’s main contractor, Lockheed Martin.

To move the spacecraft forward, the crew pushes the controller straight in – to back up, they will pull the controller out. And similarly, the controller can be pushed up or down and left or right to move in those directions. “We’re going to perform flight test objectives on Artemis II to get data on the handling qualities of the spacecraft and how well it maneuvers,” said Jeffrey Semrau, Lockheed Martin’s manual controls flight software lead for Artemis missions. “We’ll use that information to upgrade and improve our control systems and facilitate success for future missions.”
Depending on what maneuver the pilot has commanded, Orion’s software determines which of its 24 reaction control system thrusters to fire, and when. These thrusters are located on Orion’s European-built service module. They provide small amounts of thrust in any direction to steer the spacecraft and can provide torque to allow rotation control.
The cursor control device allows the crew to interact with the three display screens that show spacecraft data and information. This device allows the crew to interact with Orion even under the stresses of launch or entry when gravitational forces can prevent them from physically reaching the screens.

This device allows the crew to interact with Orion even under the stresses of launch or entry when gravitational forces can prevent them from physically reaching the screens. Next to Orion’s displays, the spacecraft also has a series of switches, toggles, and dials on the switch interface panel. Along with switches the crew will use during normal mission operations, there is also a backup set of switches they can use to fly Orion if a display or hand controller fails.
“This flight test will simulate the flying that we would do if we were docking to another spacecraft like our lander or to Gateway, our lunar space station,” said Victor Glover. “We’re going to make sure that the vehicle flies the way that our simulators approximate. And we’re going to make sure that it’s ready for the more complicated missions ahead.”
The approximately 10-day Artemis II flight will test NASA’s foundational human deep space exploration capabilities, the SLS rocket, Orion spacecraft, and supporting ground systems, for the first time with astronauts and will pave the way for lunar surface missions.

NASA Two astronauts are seated inside the Gemini spacecraft in this artist’s concept made in January 1965. The Gemini program was an early NASA human spaceflight program designed to bridge the Mercury and Apollo programs. Its main goal was to test equipment and mission procedures in Earth orbit and to train astronauts and ground crew for future Apollo missions. The first two Gemini missions were uncrewed; crew members flew on the 10 following missions.
