Rocket Lab’s Virginia launch pad opens for business, with Air Force as first customer

Rocket Lab today celebrated the opening of a launch complex on the Virginia coast, half a world away from its first launch pad in New Zealand. The California-based company's New Zealand-born CEO, Peter Beck, announced that the first liftoff from Launch Complex 2 at Virginia's Mid-Atlantic Regional Spaceport on Wallops Island would put an experimental satellite into orbit for the U.S. Air Force early next year. The Air Force's Monolith nanosatellite will test a miniaturized system tha...

It’s all systems go from NASA for uncrewed flight of Boeing’s Starliner to space station

After conducting a flight readiness review today, NASA gave its go-ahead for launching Boeing's CST-100 Starliner space taxi on an uncrewed demonstration flight to the International Space Station on Dec. 20. Starliner is due for liftoff atop a United Launch Alliance Atlas 5 rocket at 6:36 a.m. ET (3:36 a.m. PT) Dec. 20 from Cape Canaveral Air Force Station in Florida. The capsule will deliver cargo to the station, including "presents for the crew," said John Mulholland, vice president and pr...

Interstellar comet 2I -- Borisov swings past sun

Comet 2I/Borisov is a mysterious visitor from the depths of space -- the first identified comet to arrive here from another star. Hubble images capture the comet streaking though our solar system and on its way back to interstellar space. It's only the second interstellar object known to have passed through the solar system.

Demonstration of ultrafast and energy-efficient all-optical switching with graphene and plasmonic waveguides

Nippon Telegraph and Telephone Corporation and Tokyo Institute of Technology have demonstrated an ultrafast all-optical switching operation with the lowest energy consumption ever reported for all-optical switching at less than one picosecond (one trillionth of a second). The current achievement combines an ultrasmall optical waveguide with a height and width of a few dozen nanometers, called a plasmonic waveguide1, with graphene2, a material that shows great promise for nonlinear optics.

Researchers identify novel biomarkers to accurately measure dietary intake of key bioactives

Recent studies published in Nature Scientific Reports:Identify new biomarkers for measuring the intake of flavanols and procyanidins, key bioactives in apples, blueberries, grapes, pears and cocoa. Validate -- based on rigorously established criteria - the utility of these new biomarkers. Provide researchers with a path forward to accurately assess bioactive nutrient intake in large populations.

New NASA image provides more details about first observed interstellar comet

A new image from NASA's Hubble Space Telescope provides important new details about the first interstellar comet astronomers have seen in our solar system. 'Data from the Hubble Space Telescope give us the best measure of the size of comet 2I/Borisov's nucleus, which is the really important part of the comet,' said David Jewitt, a UCLA professor of planetary science and astronomy who analyzed and interpreted the data from the new image.
