Video: 00:00:57 The James Webb Space Telescope (Webb) is designed to answer fundamental questions about the Universe. One of Webb’s key science goals is to study the nearby cosmos: uncovering hidden parts of our Solar System, peering inside dust clouds where stars and planetary systems are forming, and revealing the composition of exoplanets in more detail. Exoplanets Thanks to its powerful capabilities at infrared wavelengths, Webb will offer a unique view of the outer planets in our own magnificent Solar System. Looking beyond, Webb will study in detail the atmospheres of a wide diversity of exoplanets. Webb can study exoplanets as they pass in front of their re…

Image: The James Webb Space Telescope was transferred to the final assembly building at Europe’s Spaceport in French Guiana on 7 December 2021, to meet its Ariane 5 launch vehicle. Stowed inside a special 23-tonne transport container, Webb was protected and monitored throughout the transfer. Ariane 5 was already moved to the same building on 29 November. Here, adjustable platforms allow engineers to access the launch vehicle and its payload. The next steps are to hoist Webb to the upper platform which has been prepared so that Webb can be integrated on Ariane 5’s upper stage and then encapsulated inside Ariane 5’s specially adapted fairing. Webb is scheduled for launch…

Image: Mirror, mirror, on the Moon, how far away are you? MoonLIGHT or Moon Laser Instrumentation for General relativity/geophysics High-accuracy Tests is seeking the answer to this and more questions on general relativity, the gravitational dynamics of the Earth-Moon system and the deep lunar interior. MoonLIGHT is a laser retroreflector, imaged here, which allows laser beams sent from Earth to be reflected back from the Moon to receivers on our planet. This allows very precise measurement of the distances between the reflector and the ground station. Known as lunar laser ranging, this technique has been in use since the Apollo missions to investigate Einstein’s th…

Video: 00:04:00 The world’s next generation cosmic observatory, the James Webb Space Telescope, is due for launch on an Ariane 5 from Europe’s Spaceport in French Guiana in late December. Developed and constructed over more than 30 years, Webb is a remarkable feat of engineering and technology – with the largest astronomical mirror ever flown in space, sophisticated new scientific instruments, and a sunshield the size of a tennis court. Webb is a joint project between NASA, ESA, and the Canadian Space Agency and will reveal the Universe in a whole new light. Optimised for infrared wavelengths, its detectors will be able to look back to shortly after the very dawn …

Europe’s largest satellite constellation has grown even bigger, following the launch of two more Galileo navigation satellites by Soyuz launcher from Europe’s Spaceport in French Guiana on 5 December. Galileo satellites 27-28 add to an existing 26-satellite constellation in orbit, providing the world’s most precise satnav positioning to more than 2.3 billion users around the globe.

Video: 00:01:09 The ExoMars rover used in the Earth-based Mars Terrain Simulator makes escaping from a sand trap look easy in this exercise. The rover initially has its front two wheels almost completely buried in sand, but easily escapes using its unique wheel-walking mode. It takes about 20 minutes to complete the 2 m drive – slow and careful being the key to getting out of a difficult situation. Rovers on Mars have previously been caught in sand, and turning the wheels dug them deeper, just like a car stuck in mud or snow. To avoid this, the ExoMars rover Rosalind Franklin – and its replica – has a unique wheel walking locomotion mode. Similar to leg movements,…
