megapixel space capsule

Practice run: NASA rescues its Orion space capsule When NASA sends the first humans to Mars, they will be travelling in the Orion space capsule, which offers 50% more space than did the Apollo lunar landing capsule, and can carry four astronauts. Next year, an unmanned version of the capsule will be launched using NASA’s new SLS rocket, but before that time the US Navy will be practising rescues of the 5-metre-diameter capsule for when it returns to Earth. In the photo, a copy of the capsule is being rescued by a specialised vessel that allows water to enter its lowest deck. A new light: The Blue Mountains in infrared This false-colour infrared photo shows Jamison Valley in the Blue Mountains, west of Sydney, in February 2019 during a summer of record-breaking heat.…

Patients get chemotherapy without side effects In the future, a small filter will cleanse cancer patients’ blood of chemo drugs, so they can avoid nausea and fatigue. MEDICINE Fatigue, nausea, diarrhoea and heart attacks are all side effects of chemotherapy. Although the treatment can save severely-ill cancer patients, its side effects are a major problem, as the cell toxin doesn't only attack cancer cells but also the healthy cells of the body. Scientists from the US University of California have found a solution to the problem. Some of the side effects can be avoided by injecting chemo drugs directly into a blood vessel right beside the cancer tumour, meaning that the medication is not sent through the entire body, but rather travels directly into the tumour. This doesn't solve the entire problem, however,…

A CAR WITH LEGS The carmaker Hyundai has developed a brand new car concept: vehicles that will be able to walk, as well as driving on wheels. The wheels are mounted on four legs that have five joints, allowing the car to leave the road and enter other environments, even climbing through difficult terrain. In cities, it can be used to carry disabled people with their wheelchairs right to their doorsteps. AND TALKING OF CARS… CARAVANS BECOME TRANSPARENT The truckmaker GMC has invented a system that allows you to see through your trailer or caravan. The system collects information from cameras on the back of the car and trailer to produce an image that shows the outline of the trailer (so you don't forget it's there), but also the road behind it. CONTROL YOUR CAR…

satellite to produce artificial shooting stars

AEROSPACE If fireworks are not enough to celebrate a major event, you might try something new: a shower of shooting stars. The Japanese company ALE has launched a satellite which is designed to supply shooting stars on demand. The satellite is equipped with 400 small balls that will fire towards Earth so that they burn up as shooting stars in the atmosphere. One show is to consist of 20 burning balls, so the satellite has enough ammunition to create 20 meteor showers. The precise makeup of the small balls is a trade secret, but according to ALE they are made of the same material as the small meteors that cause natural shooting stars, i.e. metals such as iron and nickel, and rock. Moreover, the company guarantees that with a ball size…

bone robot shows the first steps on dry land

EVOLUTION Modern robot technology can now show us how one of our very early ancestors moved about on Earth. Palaeontologists have long wondered which gait the first amniotes used. Amniotes originated some 350 million years ago, and they are the ancestors of reptiles, birds and mammals. Amniotes differ from amphibians by not needing to live the first part of their lives in water (as do frogs, say, as tadpoles). Scientists from the Humboldt University in Germany have made CT scans of a remarkably well-preserved fossil of the Orobates pabsti amniote, which lived some 285 million years ago. Subsequently, they recreated its skeleton, so they could see into which angles the bone joints could be turned, before they built motors to fit into the joints. The scientists also had a series of…

What makes up a massive star? The universe includes heavy stars that are much bigger than the Sun. What materials make up these stars? COSMOLOGYA star is born when a large cloud of gas and dust collapses under its own gravity. Pressure and temperature increase so much that hydrogen cores fuse into helium, liberating major quantities of energy. This is the process that makes the star bright. When a star has a mass of more than eight times that of the Sun, it is known as a 'massive' star. Massive stars have higher temperatures and pressure in their cores, making the hydrogen fuse even faster. When the hydrogen of the core is about to reach depletion, helium fuses into carbon and oxygen in the core, whereas hydrogen nuclei merge in a surrounding shell.…
