Video: 00:04:31 The double-satellite Proba-3 is the most ambitious member yet of ESA’s Proba family of experimental missions. Two spacecraft will fly together as one, maintaining precise formation down to a single millimetre. One will block out the fiery disc of the Sun for the other, to enable prolonged observations of the Sun’s surrounding atmosphere, or ‘corona’, the source of the solar wind and space weather. Usually, the corona can only be glimpsed for a few minutes during terrestrial total solar eclipses. Proba-3 aims to reproduce such eclipses for up to six hours at a time, in a highly elliptical orbit taking it more than 60 000 km from Earth. The two spacecraft are being launched together by India’s PSLV-XL launcher from the Satish Dhawan Space Centre. Follow the mission’s deployment and commissioning, up to its first glimpse of the corona, in this overview video.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s X-59 quiet supersonic research aircraft sits in its run stall at Lockheed Martin’s Skunk Works facility in Palmdale, California, firing up its engine for the first time. These engine-run tests start at low power and allow the X-59 team to verify the aircraft’s systems are working together while powered by its own engine. The X-59 is the centerpiece of NASA’s Quesst mission, which seeks to solve one of the major barriers to supersonic flight over land by making sonic booms quieter.NASA/Carla Thomas NASA’s Quesst mission marked a major milestone with the start of tests on the engine that will power the quiet supersonic X-59 experimental aircraft.
These engine-run tests, which began Oct. 30, allow the X-59 team to verify the aircraft’s systems are working together while powered by its own engine. In previous tests, the X-59 used external sources for power. The engine-run tests set the stage for the next phase of the experimental aircraft’s progress toward flight.
The X-59 team is conducting the engine-run tests in phases. In this first phase, the engine rotated at a relatively low speed without ignition to check for leaks and ensure all systems are communicating properly. The team then fueled the aircraft and began testing the engine at low power, with the goal of verifying that it and other aircraft systems operate without anomalies or leaks while on engine power.
Lockheed Martin test pilot Dan Canin sits in the cockpit of NASA’s X-59 quiet supersonic research aircraft in a run stall at Lockheed Martin’s Skunk Works facility in Palmdale, California prior to its first engine run. These engine-run tests featured the X-59 powered by its own engine, whereas in previous tests, the aircraft depended on external sources for power. The X-59 is the centerpiece of NASA’s Quesst mission, which seeks to solve one of the major barriers to supersonic flight over land by making sonic booms quieter.NASA/Carla Thomas “The first phase of the engine tests was really a warmup to make sure that everything looked good prior to running the engine,” said Jay Brandon, NASA’s X-59 chief engineer. “Then we moved to the actual first engine start. That took the engine out of the preservation mode that it had been in since installation on the aircraft. It was the first check to see that it was operating properly and that all the systems it impacted – hydraulics, electrical system, environmental control systems, etc. – seemed to be working.”
The X-59 will generate a quieter thump rather than a loud boom while flying faster than the speed of sound. The aircraft is the centerpiece of NASA’s Quesst mission, which will gather data on how people perceive these thumps, providing regulators with information that could help lift current bans on commercial supersonic flight over land.
The engine, a modified F414-GE-100, packs 22,000 pounds of thrust, which will enable the X-59 to achieve the desired cruising speed of Mach 1.4 (925 miles per hour) at an altitude of approximately 55,000 feet. It sits in a nontraditional spot – atop the aircraft — to aid in making the X-59 quieter.
Engine runs are part of a series of integrated ground tests needed to ensure safe flight and successful achievement of mission goals. Because of the challenges involved with reaching this critical phase of testing, the X-59’s first flight is now expected in early 2025. The team will continue progressing through critical ground tests and address any technical issues discovered with this one-of-a-kind, experimental aircraft. The X-59 team will have a more specific first flight date as these tests are successfully completed.
The testing is taking place at Lockheed Martin’s Skunk Works facility in Palmdale, California. During later phases, the team will test the aircraft at high power with rapid throttle changes, followed by simulating the conditions of an actual flight.

It’s like the first note of a symphony, where years of teamwork behind the scenes are now being put to the test to prove our efforts have been effective, and the notes will continue to play a harmonious song to flight.”
After the engine runs, the X-59 team will move to aluminum bird testing, where data will be fed to the aircraft under both normal and failure conditions. The team will then proceed with a series of taxi tests, where the aircraft will be put in motion on the ground. These tests will be followed by final preparations for first flight.

As NASA continues to innovate for the benefit of humanity, agency inventions that use new structures to harness sunlight for space travel, enable communications with spacecraft at record-breaking distances, and determine the habitability of a moon of Jupiter, were named Wednesday among TIME’s Inventions of 2024.
“The NASA workforce — wizards, as I call them — have been at the forefront of invention and technology for more than 65 years,” said NASA Administrator Bill Nelson. “From developing Europa Clipper, the largest satellite for a planetary mission that NASA has ever launched, to the Advanced Composite Solar Sail System, and communicating with lasers from deep space, NASA is improving our understanding of life on Earth — and the cosmos — for the benefit of all.”
Solar Sailing with Composite Booms

Like a sailboat turning to catch the wind, a solar sail adjusts its trajectory by angling its sail supported by booms deployed from the spacecraft. This demonstration uses a composite boom technology that is stiffer, lighter, and more stable in challenging thermal environments than previous designs. After launching on April 23, aboard Rocket Lab’s Electron rocket, the mission team met its primary objective by deploying the boom and sail system in space in August. Next, they will work to prove performance by using the sail to maneuver in orbit.
Results from this mission could provide an alternative to chemical and electric propulsion systems and inform the design of future larger-scale missions that require unique vantage points, such as space weather early warning satellites.
Communicating with Lasers from Deep Space
The Deep Space Optical Communications (DSOC) technology demonstration’s flight laser transceiver is seen attached to NASA’s Psyche spacecraft inside a clean room at the agency’s Jet Propulsion Laboratory in Southern California. DSOC’s tube-like gray/silver sunshade can be seen protruding from the side of the spacecraft. The bulge to which the sunshade is attached is DSOC’s transceiver, which consists of a near-infrared laser transmitter to send high-rate data to Earth and a sensitive photon-counting camera to receive ground-transmitted low-rate data.Credits: NASA/JPL-Caltech Since launching aboard NASA’s Psyche spacecraft on Oct. 13, 2023, a Deep Space Optical Communications technology demonstration has delivered record-breaking downlink data rates to ground stations as the Psyche spacecraft travels through deep space. To demonstrate the high data rates that are possible with laser communications, photos, telemetry data from the spacecraft, and ultra-high-definition video, including a streamed video of Taters the cat chasing a laser pointer, have been downlinked over hundreds of millions of miles. The mission, which is managed by NASA’s Jet Propulsion Laboratory in Southern California, has also sent and received optical communications out to Mars’ farthest distance from Earth, fulfilling one of the project’s primary goals.
Searching for Life’s Ingredients at Jupiter’s Icy Moon Europa

Credit: SpaceX The largest NASA spacecraft ever built for a mission headed to another planet, Europa Clipper also is the agency’s first mission dedicated to studying an ocean world beyond Earth. Using a suite of nine science instruments and a gravity experiment, the mission seeks to determine whether Jupiter’s moon, Europa, has conditions that could support life. There’s strong evidence that under Europa’s ice lies an enormous, salty ocean. Scientists also have found evidence that Europa may host organic compounds and energy sources under its surface. Managed by NASA’s Jet Propulsion Laboratory, the spacecraft launched on Oct. 14, and will begin orbiting Jupiter in 2030, flying by the icy moon 49 times to learn more about it.
Europa Clipper’s main science objectives are to determine the thickness of the moon’s icy shell and its interactions with the ocean below, to investigate its composition, and to characterize its geology. The detailed exploration will help scientists better understand the astrobiological potential for habitable worlds beyond our planet.
NASA’s Ames Research Center in California’s Silicon Valley manages the Advanced Composite Solar Sail System, and NASA’s Langley Research Center in Hampton, Virginia, designed and built the deployable composite booms and solar sail system. Within NASA’s Space Technology Mission Directorate (STMD), the Small Spacecraft Technology program funds and manages the mission and the Game Changing Development program developed the deployable composite boom technology.
The Deep Space Optical Communications experiment is funded by STMD’s Technology Demonstration Missions Program managed at NASA’s Marshall Space Flight Center in Huntsville, Alabama, and the agency’s Space Communications and Navigation program within the Space Operations Mission Directorate. Some of the technology was developed through NASA’s Small Business Innovation Research program.
Managed by Caltech in Pasadena, California, NASA’s Jet Propulsion Laboratory leads the development of the Europa Clipper mission in partnership with Johns Hopkins Applied Physics Laboratory in Laurel, Maryland for NASA’s Science Mission Directorate. The Applied Physics Laboratory designed the main spacecraft body in collaboration with the Jet Propulsion Laboratory as well as NASA’s Goddard Space Flight Center in Greenbelt, Maryland, NASA Marshall, and NASA Langley.

Unable to render the provided source NASA invites the public to virtually sail along with the Advanced Composite Solar Sail System‘s space journey using NASA’s “Eyes on the Solar System” visualization tool, a digital model of the solar system. This simulation shows the real-time positions of the planets, moons, and spacecraft – including NASA’s Advanced Composite Solar Sail System.
Solar sails use the pressure of sunlight for propulsion, angling toward or away from the Sun so that photons bounce off the reflective sail to push a spacecraft. This eliminates the need for heavy propulsion systems and could enable longer duration and lower cost missions. The results from this technology demonstration – including the test of the sail’s composite boom system – will advance future space exploration to expand our understanding of our Sun and solar system.
The Advanced Composite Solar Sail System, which launched in April 2024, and deployed its reflective sail in August, is currently orbiting approximately 600 miles (1,000 kilometers) above Earth and is frequently visible in the night sky to observers in the Northern Hemisphere. Fans of the spacecraft can look for the sail in the night sky using a new feature in the NASA mobile app. Visibility may be intermittent, and the spacecraft could appear at variable levels of brightness as it moves in orbit.
