TAMPA, Fla. — The satellite behind Europe’s next flagship space mission is ready to be sent to French Guiana for an April launch to explore three of Jupiter’s largest icy moons, manufacturer Airbus announced Jan. 20. The Jupiter Icy Moons Explorer (JUICE) has been undergoing final assembly and testing for nearly a year and a

WASHINGTON — NASA is suspending efforts, at least until late next year, to try to fully deploy a solar array on its Lucy spacecraft, citing diminishing returns as the spacecraft heads away from the sun. In a statement quietly posted on NASA’s website Jan. 19, the agency said the latest effort to latch one of

The company developed a satellite-based augmentation system that leverages both GPS and Europe’s Galileo WASHINGTON — The availability of a new GPS navigation signal for civilian users is creating market opportunities in so-called satellite-based augmentation systems — known as SBAS — that countries around the world are developing or upgrading to support transportation and other

WASHINGTON — The United States and Israel are finalizing an agreement that would see NASA contribute to an upcoming Israeli astrophysics mission. The focus of the agreement, which could be signed as soon as later this month, involves a mission called Ultrasat under development by Israel’s Weizmann Institute of Science with support from the Israel

A Partner in the True North On the global stage of mature space powers, Canada has earned its place, though it does not always receive the public acclaim it is due. For those in the space community, however, Canada is not only an important stakeholder but also a vital partner. As Canadian astronaut Chris Hadfield

Scaling back facilities, canceling travel and keeping staff lean helps startups stretch every dollar raised Credit: SpaceNews Midjourney illustration If it was easier to raise money, Plasmos might have a dedicated facility for testing rocket engines. Instead, the propulsion startup rented a speedboat restoration shop east of Los Angeles. There, “we managed to test something,

WASHINGTON — The European Space Agency is grappling with multiple issues that could leave Europe temporarily without its own access to space by this summer. In a Jan. 23 press briefing, ESA Director General Josef Aschbacher said that space transportation issues, including the December failure of a Vega C and the delayed introduction of the

SDA said the rebranding does not reflect any change to the mission WASHINGTON — The Space Development Agency is renaming its planned network of military satellites “Proliferated Warfighter Space Architecture,” the agency announced Jan. 23. SDA, a former Defense Department agency that is now part of the U.S. Space Force, previously used the name “National

Upright radiotherapy Leo Cancer Care’s Eve patient positioning system is installed at the Centre Léon Bérard in Lyon, France. The system uses standard immobilization devices to ensure patient stability and comfort. (Courtesy: Leo Cancer Care) Cancer patients typically lie in a supine position (on their back) during radiotherapy. But for some malignancies, including thoracic, pelvic

Join the audience for a live webinar at 6 p.m. GMT/1 p.m. EST on 22 February 2023 exploring the emerging concept of electrochemical carbon capture Want to take part in this webinar? Carbon capture is considered a critical means for climate-change mitigation. Unfortunately, conventional thermochemical methods suffer from high energy consumption, motivating the search for

[embedded content] The 2021 Nobel Prize for Physics was shared by Syukuro Manabe, Klaus Hasselmann and Giorgio Parisi “for groundbreaking contributions to our understanding of complex physical systems”. Now the Journal of Physics: Complexity has put together a special collection of open-access papers to celebrate this milestone in the history of this fascinating field. The

Corridor of light: a laser is sent down a hallway at the University of Maryland. (Courtesy: Intense Laser-Matter Interactions Lab/UMD) An optical fibre is ideal for transmitting information over long distances because its optical properties ensure that light pulses remain inside the fibre, even if the fibre curves around a corner. However, it would sometimes

Amy Smith argues that we need to rethink how we mark achievements in physics Shared passion When we talk about physics “genius”, we often see only the individual and ignore the collective efforts that have helped them.

Wind action This image of the Martian surface was taken by HiRISE on the Mars Reconnaissance Orbiter and shows yardangs. These are bedrock structures that are carved by the wind. This has created sand in the regions between the yardangs, which has been rippled by the wind. The very dark regions are shadows cast by

Light-based logic: The optical chirality logic gate is made of a nonlinear optical material that generates an output signal that’s dependent on the chirality of the two input beams. (Courtesy: Yi Zhang/Aalto University) Light-based optical logic gates operate much faster than their electronic counterparts and could be crucial for meeting the ever-growing demand for more
