DRACO began life in 2020 with the moniker “Reactor on a Rocket,” or ROAR — a name agency scientists later decided might garner negative attention.

What was Opportunity?
Together, Spirit and Opportunity represented the Mars Exploration Rover Mission (MER)—itself part of NASA’s Mars Exploration Program.
The twin missions’ main scientific objective was to search for a range of rocks and soil types and then look for clues for past water activity on Mars. Each rover, about the size of a golf cart and seven times heavier (408 pounds or 185 kilograms) than the Sojourner rover on Mars, was targeted to opposite sides of the planet in locales that were suspected of having been affected by liquid water in the past.
The plan was for the rovers to move from place to place and to perform on-site geological investigations and take photographs with mast-mounted cameras (about five feet or 1.5 meters off the ground) providing 360-degree stereoscopic views of the terrain.
3D-printed pancreatic islets may offer personalized diabetes therapy
To manufacture the human pancreatic islets, the research team had to fine-tune the settings of the 3D printer.
Scientists capture slow-motion earthquake in action
Scientists for the first time have detected a slow slip earthquake in motion during the act of releasing tectonic pressure on a major fault zone at the bottom of the ocean.
The slow earthquake was recorded spreading along the tsunami-generating portion of the fault off the coast of Japan, behaving like a tectonic shock absorber. Researchers from The University of Texas at Austin described the event as the slow unzipping of the fault line between two of the Earth’s tectonic plates.
Their results were published in Science.

New component reduces cost, supply chain constraints for fast-charging EV batteries
Strengthening the competitiveness of the American transportation industry relies on developing domestically produced electric vehicle batteries that enable rapid charging and long-range performance. The energy density needed to extend driving distance can, however, come at the expense of charging rates and battery life.
By integrating a new type of current collector, which is a key battery component, researchers at the Department of Energy’s Oak Ridge National Laboratory have demonstrated how to manufacture a battery with both superior energy density and a lasting ability to handle extreme fast charging. This enables restoring at least 80% of battery energy in 10 minutes. By using less metal, particularly high-demand copper, the technology also relieves strain on U.S. supply chains.
“This provides a significant savings on near-critical materials, because much less copper and aluminum are needed,” said lead researcher Georgios Polyzos. “At the same time, this will greatly enhance the energy density achievable with a 10-minute charge.”
Scientists achieve teleportation between quantum computers for the first time ever
Until recently, practical attempts rarely pushed beyond proof-of-concept.
Now researchers have used the teleportation trick to forge a working logic gate between two separate quantum chips sitting about six feet apart, hinting at a future where clusters of modest processors act as one mighty computer.
A qubit is valuable because it can be zero and one at the same moment, yet that superposition collapses if the qubit feels a nudge from the outside world.
