Bob Behnken and Doug Hurley are returning to Earth after two months at the ISS

We will follow the NASA coverage of the SpaceX Dragon capsule undocking and splashdown.

#ICYMI This morning, the crew members of Expedition 63 currently aboard the International Space Station shared a few remarks as they bid farewell to NASA astronauts Bob Behnken and Doug Hurley.

After just over two months of being on the space station, Bob and Doug are scheduled to undock Crew Dragon Endeavour later today, which will commence the last portion of the SpaceX Demo-2 mission, the first crewed orbital spaceflight launched from the United States since the final space shuttle mission, STS-135, in 2011. #LaunchAmerica

Authorities in Florida say a 17 year old was the “mastermind” of the attack that targeted the accounts of Barack Obama, Joe Biden, Kanye West, Bill Gates and others.

NASA astronauts Bob Behnken and Doug Hurley now face the phase of the flight that Elon Musk said is his “biggest concern.”

Oftentimes, many argue that NASA’s Space Launch System is a waste of money because it is being delayed over and over again despite having such a large budget. In this video, I will examine whether this is the case or not.

A team of researchers led by Cunjiang Yu, Bill D. Cook Associate Professor of Mechanical Engineering at the University of Houston, has developed a new form of electronics known as “drawn-on-skin electronics,” allowing multifunctional sensors and circuits to be drawn on the skin with an ink pen.

The advance, the researchers report in Nature Communications, allows for the collection of more precise, motion artifact-free health data, solving the long-standing problem of collecting precise biological data through a wearable device when the subject is in motion.

The imprecision may not be important when your FitBit registers 4,000 steps instead of 4,200, but sensors designed to check heart function, temperature and other physical signals must be accurate if they are to be used for diagnostics and treatment.

Lithium (Li) batteries, or lithium metal batteries, use metallic lithium as an anode. Over the past few decades, rechargeable Li batteries have been used to power a wide variety of electronic devices, including toys, portable consumer devices and electric vehicles.

While these batteries typically achieve reliable performances at room temperature, their energy efficiency, power and cycle life tend to decrease significantly at temperatures below −10 °C. The inability to function well at low temperatures is a crucial drawback, as it greatly limits their use in regions with particularly cold climates. The main reason for this limitation is that at temperatures below −10 °C the solid-electrolyte interphase (SEI) becomes unstable and leads to what is known as the dendritic Li plating of the anode in the batteries.

A team of researchers at Pennsylvania State University and Argonne National Laboratory recently introduced a new design for Li metal batteries that could overcome this well-documented drawback. The resulting batteries, presented in a paper published in Nature Energy, were found to perform remarkably well at low temperatures compared to previously developed Li batteries.
