NASA/Brandon Torres Navarrete Engineers at NASA’s Ames Research Center in California’s Silicon Valley, Bohdan Wesely, right, and Eli Hiss, left, complete a fit check of the two halves of a space capsule that will study the clouds of Venus for signs of life.
Led by Rocket Lab of Long Beach, California, and their partners at the Massachusetts Institute of Technology in Cambridge, Rocket Lab’s Venus mission will be the first private mission to the planet.
NASA’s role is to help the commercial space endeavor succeed by providing expertise in thermal protection of small spacecraft. Invented at Ames, NASA’s Heatshield for Extreme Entry Environment Technology (HEEET) – the brown, textured material covering the bottom of the capsule in this photo – is a woven heat shield designed to protect spacecraft from temperatures up to 4,500 degrees Fahrenheit. The probe will deploy from Rocket Lab’s Photon spacecraft bus, taking measurements as it descends through the planet’s atmosphere.
Teams at Ames work with private companies, like Rocket Lab, to turn NASA materials into solutions such as the heat shield tailor-made for this spacecraft destined for Venus, supporting growth of the new space economy. NASA’s Small Spacecraft Technology program, part of the agency’s Space Technology Mission Directorate, supported development of the heat shield for Rocket Lab’s Venus mission.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s Lucy spacecraft has its next flyby target, the small main belt asteroid Donaldjohanson, in its sights. By blinking between images captured by Lucy on Feb. 20 and 22, this animation shows the perceived motion of Donaldjohanson relative to the background stars as the spacecraft rapidly approaches the asteroid.
NASA’s Lucy spacecraft’s first views of the asteroid Donaldjohanson. The asteroid is circled on the left to guide the eye.NASA/Goddard/SwRI/Johns Hopkins APL Lucy will pass within 596 miles (960 km) of the 2-mile-wide asteroid on April 20. This second asteroid encounter for the Lucy spacecraft will serve as a dress-rehearsal for the spacecraft’s main targets, the never-before-explored Jupiter Trojan asteroids. Lucy already successfully observed the tiny main belt asteroid Dinkinesh and its contact-binary moon, Selam, in November 2023. Lucy will continue to image Donaldjohanson over the next two months as part of its optical navigation program, which uses the asteroid’s apparent position against the star background to ensure an accurate flyby.
Donaldjohanson will remain an unresolved point of light during the spacecraft’s long approach and won’t start to show surface detail until the day of the encounter.
From a distance of 45 million miles (70 million km), Donaldjohanson is still dim, though it stands out clearly in this field of relatively faint stars in the constellation of Sextans. Celestial north is to the right of the frame, and the 0.11-degree field of view would correspond to 85,500 miles (140,000 km) at the distance of the asteroid. In the first of the two images, another dim asteroid can be seen photobombing in the lower right quadrant of the image. However, just as the headlights of an approaching car often appear relatively stationary, Donaldjohanson’s apparent motion between these two images is much smaller than that of this interloper, which has moved out of the field of view in the second image.
These observations were made by Lucy’s high-resolution camera, the L’LORRI instrument — short for Lucy LOng Range Reconnaissance Imager — provided by the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland.
Asteroid Donaldjohanson is named for anthropologist Donald Johanson, who discovered the fossilized skeleton — called “Lucy” — of a human ancestor. NASA’s Lucy mission is named for the fossil.
Lucy’s principal investigator, Hal Levison, is based out of the Boulder, Colorado, branch of Southwest Research Institute, headquartered in San Antonio. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, provides overall mission management, systems engineering, and safety and mission assurance. Lockheed Martin Space in Littleton, Colorado, built the spacecraft. Lucy is the 13th mission in NASA’s Discovery Program. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the Discovery Program for the Science Mission Directorate at NASA Headquarters in Washington.

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.

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.
