‍Here are details on the feasibility study with SpaceX to boost Hubble into a higher orbit. The non-exclusive study is designed to help the agency understand the commercial possibilities of servicing missions. Article @EverythingScience

NASA and SpaceX have signed a space act agreement for a commercial mission to boost the Hubble Space Telescope. This will extend the lifetime of the telescope, and preclude emerging concerns about the need for costly end-of-life disposal. Source: @SciGuySpace

Tiny Robots Have Successfully Cleared Pneumonia From The Lungs of Mice The microbots are made from algae cells and covered with a layer of antibiotic nanoparticles. The algae provide movement through the lungs, which is key to the treatment being targeted and effective. In experiments, the infections in the mice treated with the algae bots all cleared up, whereas the mice that weren't treated all died within three days. The technology is still at a proof-of-concept stage, but the early signs are very promising. Article @EverythingScience

NASA is going to impact their DART small satellite into Diomorphos asteroid, as a method of planetary defense test NASA’s Double Asteroid Redirection Test (DART) is set to make history next Monday (3rd Oct) as the world’s first planetary defense test, and the spacecraft’s own “mini-photographer” LICIACube (short for Light Italian CubeSat for Imaging Asteroids) is warming up to capture the event.

Designing a way to make oxygen injectable What if emergency medical personnel could treat a desperately ill patient in need of oxygen with a simple injection instead of having to rely on mechanical ventilation or rush to get them onto a heart-lung bypass machine? A new approach to transporting gases using a class of materials called porous liquids represents a big step toward artificial oxygen carriers and demonstrates the immense biomedical potential of these unusual fluids.

Webb’s NIRCam instrument draws attention to bright, hot features, such as the massive young stars in blue. As seen here, its MIRI instrument sees in longer wavelengths of light, uncovering cooler gas and dust deeper within the clouds. #Webb Read more @EverythingScience

This Webb caught a giant space tarantula! Take a moment to stare into thousands of never-before-seen young stars in the Tarantula Nebula. Webb reveals details of the structure and composition of the nebula, as well as background galaxies The Tarantula Nebula gets its name from its dusty filaments. The largest and brightest star-forming region near our galaxy, it's home to the hottest, most massive stars known! This nebula lets us see what star formation might have looked like at its peak in our cosmic history. Read more @EverythingScience

Finally! There's Now a Way to Send Text Messages on Your Phone Underwater You may not have given much thought to being able to text underwater, but for millions of scuba diving and snorkeling enthusiasts, communication in the ocean is pretty essential to staying safe. "Other than downloading an app to their phone, the only thing people will need is a waterproof phone case rated for the depth of their dive," says Chen. That app is AquaApp, and it can work with speakers and microphones on ordinary smartphones – or even smartwatches. It gives users 240 preset messages to pick from, split into eight categories for easier access. In tests in a variety of scenarios, the team found the app was effective at communicating messages across a distance of 30 meters (98 feet). For shorter-length messages – emergency SOS messages, for example – the app can go up to 100 meters (nearly 330 feet). This is all managed without a huge drain on battery life.

Cannabis users no more likely to lack motivation than non-users: Study breaks 'stoner' stereotype Adult and adolescent cannabis users are no more likely than non-users to lack motivation or be unable to enjoy life's pleasure, new research has shown, suggesting there is no scientific basis for the stereotype often portrayed in the media. Cannabis users also show no difference in motivation for rewards, pleasure taken from rewards, or the brain's response when seeking rewards, compared to non-users. Article @EverythingScience

NASA unsure next Moon rocket launch attempt possible this month After scrapping a second attempt to get its new 30-story lunar rocket off the ground due to a fuel leak, NASA officials said Saturday it may not be possible to try again this month. The current launch window for NASA's Artemis 1 mission to the Moon ends Tuesday and is "definitely off the table," said Jim Free, associate administrator for Exploration Systems Development, at a press conference Saturday. The next possible launch window is September 19 to October 4, and failing that, October 17 to 31, NASA said. The ability to take off during those windows "will really depend on the options that the team comes back with likely on Monday or early Tuesday morning," said Free. Article @EverythingScience
