Astronauts practise tasks in simulated moon environment and underwater. Astronauts have been practising walking on the Moon as their next-generation spacesuit passes milestone testing. NASA astronauts and spacesuit engineers recently simulated lunar surface operations and tasks underwater wearing the new suits, built by Axiom Space, to demonstrate safety and mobility. The space agency reported Thursday (Feb 12) that the spacesuit has passed a contractor-led technical review and is hoped to be used for the Artemis III mission as NASA prepares to send humans to the Moon???s South Pole for the first time.

Janette Kerr PPRWA Hon. RSA, Twenty Solargraphs from the Solargraphic Project 2020-24 Formless 2024-25 (exposure time 18 months) Solargraph on paper Kerr collaborated with communities in Iceland, Greenland, Shetland and Somerset, to record the slow passage of time in different landscapes. The solargraphic process is a form of long-exposure photography. Kerr captures the arc of the Sun, as it moves across the sky from dawn to dusk, on photographic paper sealed in DIY pinhole cameras made from drinks cans. Her approach combines science and art, chemistry and the digital processing of the final image. Slow Time. The Sun rises and falls each day, its gradual trek discreetly recorded by small tin cans whose uninterrupted gaze captures every photon of sunlight travelling across the sky. Solargraphy (from the Latin solar, of the sun, and graphia, writing) is a form of long-exposure photography that captures the Sun moving across the sky. It combines science and art, chemistry and [today] digital elements. Being able to capture an extended period of time in a single frame, far beyond the capacity of the human eye, is incredible enough, but even more amazing is how simple it is. A low-tech process, solargraphy typically uses pinhole cameras made from used drinks cans. Sheets of black-and-white photographic paper can be sealed inside the cans, and then the cameras are fixed outdoors, facing south [in the Northern Hemisphere]. We usually think of photography as an instant process, images captured digitally in a fraction of a second. Solargraphs by Kerr have been recorded over a period of 1?18 months, mapping landscape in slow time. Light waves are captured as they travel through the air, passing through a pinhole in the side of the can and slowly etching an image on photographic paper curved around the inside. The resulting images are shaped by landscape and the Sun?s daily elevation. Actions of the environment ? rain and other elemental detritus, or the can?s unexpected movement ? also leave traces on the final pictures, yet moving objects leave no trace. Solargraphy is a ?printing-out? process: this is where an image forms on photographic paper solely through the action of light, without using chemicals to develop the image. Light provides the energy required for silver halides (salts) in the photographic paper to change to a visible state. When silver halides are exposed to light, free metallic silver atoms are ?liberated?, forming a latent image. Over a prolonged exposure of several months the silver halide particles clump together, increasing in size. The photographic paper slowly becomes coloured, transitioning from yellow to sepia and then pink, even slate grey. (In traditional photography, the latent image would be chemically developed in a darkroom.) For contemporary solargraphy, the image captured on the paper can be scanned and manipulated, using a photo-editing program on a laptop, to form a digital record. A solargraphic project was initiated by Kerr during various residencies, and in collaboration with communities in Iceland, Greenland, Shetland and Somerset. The final images that she produces show the Sun?s progress as an accumulation of arcing and streaking lines, leaving ghostly exposures of landscape seen in slow time, out of phase with human activity. w3w: ///reporters.survived.formless (Coleford, Somerset) 2024?5 Solargraph on paper (exposure time: 18 months) 21 x 30cm COURTESY OF THE ARTIST

TUNSTALL, ENGLAND - JANUARY 24: In this aerial view people view a decommissioned cold war nuclear observation post has fallen on to the beach after clinging perilously to the cliff face for the last month on January 24, 2026 in Tunstall, England. The decommissioned bunker, known as Tunstall ROC (Royal Observer Corps), is believed to have been built in 1959 as a nuclear monitoring post during the Cold War. Rapid erosion along the East Yorkshire coastline left it exposed and caused it to collapse. (Photo by Christopher Furlong/Getty Images)
