NASA awards major Artemis contract for at least six Orion spacecraft

NASA anticipates a long line of Artemis missions -- as many as 12, the space agency said today -- which is why it has awareded a new contract to Lockheed Martin for as many as six Orion spacecraft. Called the Orion Production and Operations Contract (OPOC), this deal taps Lockheed for between six and 12 Orion spacecraft through the year 2030.

Venus may have had liquid water until 700 million years ago

Venus may have had liquid water until 700 million years ago

When we talk about planets that had water in the distant past, Mars is usually the planet we are talking about. Scientists have now stated that it is possible that Venus was a temperate planet with liquid water on its surface for 2-3 billion years. Some sort of dramatic transformation began to happen about 700 million years ago causing the planet to become the Venus we know now.

Researchers create a battery that bends and flexes

Researchers create a battery that bends and flexes

If smartphone makers ever get folding devices ready for the mainstream market in a significant way, one thing that the devices will need is flexible batteries. As it is today, batteries are rigid devices that can overheat when bent or broken. Scientists from ETH Zurich have created a new type of battery that is flexible.

Researchers disprove prevailing theory on what holds DNA together

Researchers disprove prevailing theory on what holds DNA together

Scientists at Chalmers University of Technology in Sweden have disproven a prevailing theory of what holds DNA together. The prevailing theory has been that hydrogen bonds the two sides of the DNA structure together. The researchers for Chalmers have disproven that theory and say that water is key to holding DNA together.

NASA says Australia will help support its Artemis and Moon to Mars efforts

NASA says Australia will help support its Artemis and Moon to Mars efforts

During a ceremony held on Saturday, NASA and the Australian Space Agency announced a new commitment between the two that will result in Australia helping support NASA's efforts to return humans to the Moon. The two space agencies signed a joint statement of intent at a ceremony in Washington, D.C., on Saturday. Under the arrangement, Australia will support US efforts in cases of 'mutual interest.'

ESA’s new Mars image shows the Red Planet bathed in blue

ESA’s new Mars image shows the Red Planet bathed in blue

The European Space Agency has published a new image showing a 'slice' of Mars, one that ranges from the planet's white cloud-covered north pole down through a band of pocked orange landscape to dark blue southern terrain. The image results from observations made by the ESA's Mars Express spacecraft, offering a unique, colorful, and highly detailed look at the barren planet.

Nanochains could increase battery runtime and speed charging

Nanochains could increase battery runtime and speed charging

Researchers at Purdue University have announced a breakthrough that could have a significant impact on batteries of the future. The team says that the runtime for the battery in a phone or computer depends on how many lithium-ions can be stored in the negative electrode material inside the battery. When those ions are depleted, the battery is unable to deliver an electrical current.

NASA is testing ARADS rover with a fancy drill for deep

NASA has announced that it is testing a new tool that may one day head to Mars to help with the search for life on the Red Planet. The tool is attached to a rover being tested in the Atacama Desert in Chile called ARADS. The tool being tested is a drill that is meant to dig deep under the surface of Mars.

NASA’s new Mars image shows sandy ‘steps’ in a big impact crater

NASA’s new Mars image shows sandy ‘steps’ in a big impact crater

Southwest of Mars' Arabia Terra region lies a landmark called Danielson Crater, an impact crater that has existed on the planet for 'millions or billions' of years, according to NASA. At some point after the crater formed, sediment began to settle into the large hole in layers, slowly becoming cemented into place. Eons of formation and erosion have resulted in a striking landscape, one recently shared by NASA in a new image.

Researchers build a robot using smaller robots called “smarticles”

The building of a robot typically involves the same sort of components no matter what the purpose of the bot is. Robots need things like motors, actuators, body segments, legs, and wheels. Researchers from the Georgia Institute of Technology have created a larger robot using smaller robots known as "smarticles." Smarticles is short for smart active particles.

NASA image shows off volcanic moon Io casting a shadow on Jupiter

NASA is always sharing cool images of something going on in the solar system, and this shot of Jupiter is no exception. The image shows a round solar eclipse on the surface of Jupiter cast by the shadow of Io as it orbits the giant planet. Io is an interesting satellite and was the first volcanically active object discovered outside of the Earth.

UCLA OsciBot is powered and steered by light

UCLA OsciBot is powered and steered by light

Researchers at UCLA have created a new design for a swimming robot that is powered and steered by constant light. The robot the team devised is called the OsciBot and it moves by oscillating its tail. Researchers hope that the design might eventually lead to designs for ocean-going robots and autonomous ships.
