Galileo R&D tests new uplink antenna

Panel of newly developed phased array antenna

Galileo relies on ground-based uplink stations (ULS) to maintain accurate positioning for users worldwide. These stations transmit essential data to the satellites, including the information required to compute the satellites' orbits and clock corrections. Traditionally, such messages are sent using dish antennas. However, a new type of ground uplink antenna – a phased array antenna – was recently tested at the European Space Agency’s (ESA) site in Redu, Belgium. Developed under ESA's Horizon 2020 programme for R&D, which aims to keep Galileo up to date with the latest innovations, this innovative antenna could benefit

Fly over Xanthe Terra with Mars Express

Video: 00:03:16

ESA’s Mars Express takes us on another mesmerising flight over curving channels carved by water, islands that have resisted erosion, and a maze of hilly terrain.

Central to the tour is a 1300 km-long outflow channel called Shalbatana Vallis. It cascades down from the highland region of Xanthe Terra to the smoother lowlands of Chryse Planitia.

Billions of years ago, water surged through this channel, creating many of the features we see today.

The tour culminates in a spectacular view of a 100 km-wide impact crater, smashed out of Mars’s surface when it collided with a space rock.

Enjoy the flight, and be

Momentus Inc. has signed a contract to launch a demonstration mission for Pulsar Fusion's next-generation Hall Effect Thruster (HET) propulsion system. The U.S.-based satellite services provider will integrate Pulsar's technology aboard its Vigoride orbital service vehicle, with launch scheduled for late 2026. The mission is designed to provide Pulsar with an in-orbit platform to validate

ESA has signed a contract with Avio to develop a demonstration mission for a reusable rocket upper stage, marking a step toward fully reusable European launch systems. The program will define system requirements, explore disruptive solutions, and deliver preliminary designs for both flight and ground infrastructure. The initiative builds on previous industrial work and aims to reduce risks

In the 17th century, astronomers Christiaan Huygens and Giovanni Cassini trained their telescopes on Saturn and uncovered a startling truth: the planet's luminous bands were not solid appendages, but vast, separate rings composed of countless nested arcs. Centuries later, NASA's Cassini-Huygens (Cassini) probe carried the exploration of Saturn even further. Beginning in 2005, it sent back

Growing evidence suggests that a subsurface ocean lurks beneath the icy surface of Uranus' moon Ariel, but new research, published in Icarus, characterizes the possible evolution of this ocean, and found that it may have once been over 100 miles (170 kilometers) deep. For perspective, the Pacific Ocean averages 2.5 miles (4 kilometers) deep. "Ariel is pretty unique in terms of icy moons,"

Honda Motor Co. and Astrobotic Technology have entered a joint development agreement to investigate scalable lunar power solutions that combine Honda's regenerative fuel cell (RFC) system with Astrobotic's Vertical Solar Array Technology (VSAT) and LunaGrid service. The collaboration aims to deliver continuous and reliable power for extended lunar surface operations, particularly during the two-
