A spectrometer will analyze the gamma rays and neutrons produced when Psyche is struck by cosmic rays. 光谱仪将会分析灵神星在宇宙射线照射下所产生的伽玛射线和中子。 Each element in the periodic table releases gamma rays of specific wavelengths, 元素周期表内的每个元素都会释放特定波长的伽玛射线, so...
NASA’s interactive Eyes on Earth satellite map shows the location and rendering of NASA satellites orbiting Earth, as well as decades of data that they’ve collected.
Water: While Mars is dry and arid today, evidence suggests that it may have had liquid water in the past. Ancient riverbeds, lake basins, and signs of water erosion indicate that Mars once had a much wetter and possibly warmer environment. ...
National Aeronautics & Space Administration (NASA) has cancelled the space flight to deploy the Alpha Magnetic Spectrometer (AMS), which is designed to detect high-energy charged cosmic rays in space and perhaps discover unknown pulsars and x-ray sources and observe dark matter. The project was ...
"We don't have the solution yet in terms of shielding, in terms of protecting you from cosmic rays and solar flares that you experience during this transit time," Jones said. Aerospace experts have identified several technologies that need rapid development, including spacecraft that can survive...
These early stars, referred to (somewhat confusingly) as Population III (Pop III) stars, were very different from the sun and other stars seen in the cosmos today. That's because the universe wasn't yet filled with "metals," the term astronomers use to describe elements heavier than hydrog...
The Imaging X-ray Polarimetry Explorer, or IXPE, mission is assigned to launch on a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. IXPE is designed to measure the polarization of high-energy cosmic X-rays, collecting data that will allow astronomers to study the unseen...
Jim Green: Well, Knicole, I always like to ask my guest to tell me what was that event or person, place, or thing that happened to them that got them so excited that they became the scientist they are today. I call that event a gravity assist. So, Knicole, what was your gravity...
were originally simple gas molecules. However, under the strong energy released by cosmic rays, ...
RadLab features a visualization portal (https://visualization.osdr.nasa.gov/radlab) and an API (https://visualization.osdr.nasa.gov/radlab/api) that facilitates data queries by craft, sensor type, time range and radiation type (e.g. galactic cosmic rays, solar particle events, the ...
