  1. NIST 'Noise Thermometry' Yields Accurate New Measurements Of Boltzmann ConstantRead the original story

    Friday Jun 30 | ECNmag

    By measuring the random jiggling motion of electrons in a resistor, researchers at the National Institute of Standards and Technology have contributed to accurate new measurements of the Boltzmann constant, a fundamental scientific value that relates the energy of a system to its temperature. NIST made one measurement in its Boulder, Colorado, laboratory and collaborated on another in China.

  2. Novel Use Of Satnav Saves Precious WaterRead the original story

    May 15, 2017 | ECNmag

    Water conservation is a growing concern globally, and particularly for farmers in the USA, where decades of irrigating huge fields has depleted vital resources of fresh surface water and groundwater. An ESA spin-off that can help to preserve water supplies while guaranteeing crop irrigation is now undergoing final testing.

  3. Sounding Rocket Will Take 1,500 Images Of Sun In Five MinutesRead the original story

    May 4, 2017 | ECNmag

    On May 5, 2017, scientists will launch a sounding rocket 200 miles up into the atmosphere, where in just five minutes, it will take 1,500 images of the sun. The NASA-funded RAISE mission is designed to scrutinize split-second changes occurring near the sun's active regions-areas of intense, complex magnetic activity that can give rise to solar flares, which eject energy and solar material out into space.

  4. NASA's Webb Telescope Completes Goddard Testing, Heading To Texas For MoreRead the original story

    May 3, 2017 | ECNmag

    NASA's James Webb Space Telescope has successfully passed the center of curvature test, an important optical measurement of Webb's fully assembled primary mirror prior to cryogenic testing, and the last test held at NASA's Goddard Space Flight Center in Greenbelt, Maryland, before the spacecraft is shipped to NASA's Johnson Space Center in Houston for more testing. After undergoing rigorous environmental tests simulating the stresses of its rocket launch, the Webb telescope team at Goddard analyzed the results from this critical optical test and compared it to the pre-test measurements.

  6. New Horizons Halfway from Pluto to Next Flyby TargetRead the original story

    Apr 4, 2017 | ECNmag

    How time and our spacecraft fly - especially when you're making history at 32,000 miles per hour. Continuing on its path through the outer regions of the solar system, NASA's New Horizons spacecraft has now traveled half the distance from Pluto - its storied first target - to 2014 MU69, the Kuiper Belt object it will fly past on Jan. 1, 2019.

  7. New Engineered Material Can Cool Roofs, Structures with Zero Energy ConsumptionRead the original story

    Feb 9, 2017 | ECNmag

    A team of University of Colorado Boulder engineers has developed a scalable manufactured metamaterial -- an engineered material with extraordinary properties not found in nature -- to act as a kind of air conditioning system for structures. It has the ability to cool objects even under direct sunlight with zero energy and water consumption.

  8. NOAA's GOES-16 EXIS Instrument Observes Solar FlaresRead the original story

    Feb 3, 2017 | ECNmag

    Solar flares are huge eruptions of energy on the sun and often produce clouds of plasma traveling more than a million miles an hour. When these clouds reach Earth they can cause radio communications blackouts, disruptions to electric power grids, errors in GPS navigation, and hazards to satellites and astronauts.

  9. New Horizons Refines Course for Next FlybyRead the original story

    Feb 2, 2017 | ECNmag

    NASA's New Horizons spacecraft completed a short propulsive maneuver Wednesday to refine its track toward a New Year's Day 2019 flyby past 2014 MU69, a Kuiper Belt object some 4 billion miles from Earth. Telemetry confirming that the engine burn went as planned reached the New Horizons mission operations center at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, via NASA's Deep Space Network stations in Goldstone, California and Canberra, Australia, shortly after 1:15 p.m. EST.

  10. Similar-Looking Ridges on Mars Have Diverse OriginsRead the original story

    Jan 26, 2017 | ECNmag

    Thin, blade-like walls, some as tall as a 16-story building, dominate a previously undocumented network of intersecting ridges on Mars, found in images from NASA's Mars Reconnaissance Orbiter. The simplest explanation for these impressive ridges is that lava flowed into pre-existing fractures in the ground and later resisted erosion better than material around them.

  11. NASA Selects Two Missions to Explore the Early Solar SystemRead the original story

    Jan 5, 2017 | ECNmag

    NASA has selected two missions that have the potential to open new windows on one of the earliest eras in the history of our solar system - a time less than 10 million years after the birth of our sun. The missions, known as Lucy and Psyche , were chosen from five finalists and will proceed to mission formulation, with the goal of launching in 2021 and 2023, respectively.

  12. NASA Completes Webb Telescope Center of Curvature Pre-testRead the original story

    Nov 2, 2016 | ECNmag

    Engineers and technicians working on the James Webb Space Telescope successfully completed the first important optical measurement of Webb's fully assembled primary mirror, called a Center of Curvature test. Taking a "before" optical measurement of the telescope's deployed mirror is crucial before the telescope goes into several stages of rigorous mechanical testing.
