NASA “memory metal” tires could give future Mars rovers a wheel upgrade

NASA “memory metal” tires could give future Mars rovers a wheel upgrade

NASA is working on shape memory alloy tires for future missions to Mars, figuring out ways to give rovers and more an airless, shapeshifting wheel. While NASA's Perseverance rover is headed off to Mars later this year with six aluminum wheels, in the future NASA vehicles - and vehicles a lot closer to home - could take advantage of memory metals.

Scientists find the first evidence of Martian rivers in long-term action

Scientists find the first evidence of Martian rivers in long-term action

Scientist have known that Mars, at some point in its life, had water on its surface. Scientists have now found the first evidence of rivers in long-term action preserved in the rock of an exposed cliff-face on the Red Planet. The team says that rivers continuously shifted in their gullies, creating sandbanks similar to the Rhine or rivers found in Northern Italy.

ESO astronomers discover a black hole only 1000 light-years from Earth

ESO astronomers discover a black hole only 1000 light-years from Earth

A group of astronomers from the European Southern Observatory, or ESO, and other institutes has discovered a black hole that's only 1000 light-years from Earth. While the distance is vast, the new black hole is closer to our Solar System than any other black hole found so far. The black hole forms part of a triple system that can be seen with the naked eye.

NASA details precise microbial ‘fingerprints’ astronauts leave in space

NASA has detailed a new study that found precise microbial 'fingerprints' that astronauts left behind on the International Space Station. According to the research, microorganisms transferred from astronauts' bodies to the ISS environment retained a close resemblance to their source and scientists were able to determine which part of the astronaut's body they came from.

Artemis Accords moon mining pact in the works with Trump admin: Report

Artemis Accords moon mining pact in the works with Trump admin: Report

A "legal blueprint for mining on the moon" was tipped to be in the works in the White House under the U.S.-sponsored international agreement called the Artemis Accords. A report this week suggests that a draft pact has not yet been "formally shared" with any U.S. allies as of yet. This agreement would be made in association with NASA and ideally agreed upon by by government officials around the world.

Scientists discover bands of clouds streaking across a brown dwarf

Astronomers have detected something interesting on the surface of a cool star-like body known as a brown dwarf. The team of astronomers has identified what appear to be bands of clouds that are streaking across the surface of the brown dwarf. Those cloud bands are said to resemble clouds that stripe the surface of Jupiter and were discovered using a technique called polarimetry.

Researchers have created a working rotating detonation engine

Researchers have created a working rotating detonation engine

A team of researchers in Florida, working with the United States Air Force, claim to have built and tested an experimental model of a rotating detonation rocket engine. This type of engine uses spinning explosions inside a ring channel to create extremely efficient thrust. The engine is capable of running until the fuel is turned off.

Tom Cruise, SpaceX to shoot a film on the International Space Station

Tom Cruise, SpaceX to shoot a film on the International Space Station

There have been countless movies that have been set in outer space but not all of them can make a claim to be really based on reality. For that to happen, one will have to actually be in space or at least shoot some scenes there. Considering the logistics, not to mention legal and regulatory requirements, of that stunt, it's no surprise that almost no one has even bothered to do so. Tom Cruise and SpaceX, however, want to change that and they have their eyes on the ISS from the get-go.

MIT researchers think life may thrive on hydrogen planets

MIT researchers think life may thrive on hydrogen planets

Sara Seager, the Class of 1941 Professor of Planetary Science, Physics, and Aeronautics and Astronautics at MIT, wants to avoid a situation where humans might encounter alien organisms but fail to recognize it as actual life. Seager wants to cast a wider net when looking for environments beyond our own that might be habitable. Seager and fellow researchers recently published a paper noting observations and laboratory studies that show microbes can survive and thrive in atmospheres that are dominated by hydrogen.

Stanford researchers demonstrate a new method to transmit electricity wirelessly

Engineers at Stanford have demonstrated a new method of transmitting electricity wirelessly to multiple devices. The wireless electricity transmission system they developed could send electricity to electric cars, robots, and drones as they move. The team says that the technology would need to be scaled up to be able to power electric cars as they drive on highways or to power robots on factory floors.

Researcher’s ultrafast camera snaps 70 trillion frames per second

Researcher’s ultrafast camera snaps 70 trillion frames per second

A researcher from Caltech named Lihong Wang has created a new ultrafast camera capable of taking images extremely quickly. The ultrafast camera can snap images at a rate of 70 trillion per second. The team says in the length of time it takes a person to blink their eye; the camera can take trillions of pictures.

These “superhuman eyes” will give NASA’s Perseverance rover its edge on Mars

NASA has detailed the advanced cameras that will give the Perseverance rover its "eyes" on Mars, a huge step up from previous Martian robots, as it readies the lab-on-wheels for its big trip to the red planet. If all goes to plan, NASA intends to launch Perseverance sometime in late July or early August of this year.
