Space has a hostile radiation environment that increases the risk of cancers in humans and malfunctions in spacecraft electronics. The types of space radiation of primary concern are: Galactic Cosmic Rays from outside our solar system generated by supernovae and other phenomena; Solar Energetic Particles produced by the Sun during intense and sporadic bursts of activity; and Trapped Radiation: energet

Our atmosphere protects us from a hostile space radiation environment comprising high energy particles of solar and intergalactic origin. Solar radiation is significant during unpredictable and short lived solar flares and coronal mass ejections (CMEs); however, galactic cosmic radiation (GCR) is omnipresent. The GCR intensity varies with latitude, longitude, and time due to effects of solar activity on the interplanetary magnetic field, as well as the Earth's magnetic field. Space radiation collides with gases in the atmosphere, leading to a complex shower of high energy radiation, the intensity and composition of which varies spatially and temporally. Excessive exposure to radiation can damage DNA and lead to long-term health effects such as an increased risk of cancer. Resulting radiation levels at commercial aircraft altitudes are greater than at sea level. Aircrew are classified as radiation workers in some countries; however, planning to limit their exposure, and monito
The World Magnetic Model calculates the intensity and direction of the Earth's magnetic field on a specific date-time, geodetic altitude, latitude, and longitude. It is relied upon throughout the world for navigation, mineral exploration, atmospheric and space science, and is installed on billions of devices. A comprehensive description of the World Magnetic Model, including its limitations, can be found here. We provide a RESTful API to access the out-of-cycle World Magnetic Model (WMM2015v2) valid for years 2015.0 - 2020.0 and WMM2020 valid for years 2020.0 - 2025.0 API requests must contain a key "API-Key" in the header (see code samples).

The gravitational field of the earth is non-uniform. The geoid is the shape the ocean surface would take if only gravity and the rotation of the Earth were considered. The geoid is the surface that defines zero elevation. The geoid height is the difference between an ideal reference ellipsoid and the geoid. The gravity anomaly is the difference between the acceleration due to gravity on the Earth's surface and the value calculated assuming the reference ellipsoid. The official Earth Gravitational Model EGM2008 was developed and released to the public by the National Geospatial-Intelligence Agency (NGA). Our EGM2008 API provides on-demand access to the EGM2008 model, as implemented by the open-source GeographicLib Gravity library. API requests must
Space has a hostile radiation environment that increases the risk of cancers in humans and malfunctions in spacecraft electronics. The types of space radiation of primary concern are: Galactic Cosmic Rays from outside our solar system generated by supernovae and other phenomena; Solar Energetic Particles produced by the Sun during intense and sporadic bursts of activity; and Trapped Radiation: energetic particles confined by Earth's magnetic field, usually comprising an inner belt of mostly high energy protons and an outer belt dominated by lower energy electrons and plasma. Understanding the space radiation environment for a particular mission profile is becoming increasingly important. Commercial off-the-shelf electronic components that aren't resilient to space radiation are now prevalent. Longer duration missions to cislunar space, Mars, and beyond
