Launched in November 2013, three Swarm satellites will provide new insights into many natural processes related to Earth’s magnetic field: from those occurring deep inside the planet to the near-Earth electromagnetic environment and the influences of the solar wind. Each of the Swarm satellites provides high-precision and high-resolution measurements of the strength, direction and variation of the magnetic field, complemented by precise navigation, accelerometer, plasma and electric field measurements.
There could be at least 320,000 viruses awaiting discovery that are circulating in animals, a study suggests.
Instruments aboard satellites make global measurements daily. But processing can take up to 40 hours. Agencies and others require these Earth Observing System products in near-real-time for everything from weather forecasting to national security. This article describes a NASA project called LANCE that processes data in three hours.
