Still cruising toward its operating orbit nearly a million miles from Earth, the $10 billion James Webb Space Telescope completed a transformation into its final dimension Saturday with the last of some 50 post-launch deployments, the unfolding of the observatory’s 21.3-foot (6.5-meter) primary mirror.
A reboot of Alien vs. Predator, one of the most profitable transmedia sci-fi crossovers ever, might just be the next big film that Disney is looking for.

NASA's 10 new astronaut candidates are reporting to work to begin two years of basic training. The four women and six men are embarking on new careers to be space station and Artemis crew members.
ESA’s exoplanet mission Cheops has revealed that an exoplanet orbiting its host star within a day has a deformed shape more like that of a rugby ball than a sphere. This is the first time that the deformation of an exoplanet has been detected, offering new insights into the internal structure of these star-hugging planets.
70% of astronauts who spend time on the International Space Station (ISS) experience swelling at the back of their eyes, causing blurriness and impaired eyesight both in space and when they return to Earth. Sometimes, it’s permanent. Understanding the way microgravity affects the eyes, and the human body as a whole is an essential part of preparations for future long-duration spaceflights to the Moon and Mars. In an effort to understand the cause of these eye problems, researchers at the Medical University of South Carolina used MRI scans of twelve ISS astronauts to measure the intracranial venous system (veins that circulate blood to the brain) before and after flight. They’ve determined that there is a strong connection between the swelling of these veins and the onset of eye trouble.

Join ESA astronaut Matthias Maurer inside Kibo, the Japanese laboratory module of the International Space Station in 360°, setting up Astrobee robotic free-flyers for the ReSWARM experiment, short for RElative Satellite sWArming and Robotic Maneuvering. The robotics demonstration tests autonomous microgravity motion planning and control for on-orbit assembly and coordinated motion.
The robotic arm on China’s space station has moved a cargo spacecraft in a crucial test for new module additions.

Let’s not sugarcoat it. Exploring the Moon is not for the faint of heart! It’s an airless body, which means there is no atmosphere, the surface temperatures are extreme, and there’s lots of radiation. The low gravity also means you can never really walk on the surface and have to bounce around in a bulky spacesuit until you fall over. And you can bet your bottom dollar people will make a supercut of the footage someday (see below). Then there’s that awful moondust (aka. lunar regolith), which is electrostatically charged and sticks to EVERYTHING!
From a Christmas launch to a tricky deployment, NASA's James Webb Space Telescope is now successfully deployed and scientists are thrilled.
