Explorers and Heliophysics Projects Division (EHPD)

The Explorers and Heliophysics Projects Division (EHPD) consists of three programs: Explorers, Living With a Star (LWS), and Solar Terrestrial Probes (STP). The Explorers Program is an uncoupled Program which provides frequent flight opportunities for world-class scientific investigations from space within NASA Heliophysics and Astrophysics Space Science goals. Explorers projects are typically implemented in the Principal Investigator (PI) mode. The LWS Program is a loosely coupled Program which provides missions to improve our understanding of how and why the Sun varies, how the Earth and Solar System respond, and how the variability and response affects humanity in Space and on Earth. The STP Program is an uncoupled Program which provides missions to understand the fundamental physics processes from the Sun to Earth, to outer planets, and beyond to the interstellar medium.

AIM spacecraft shows the sky over Antarctica is glowing electric blue due to the start of noctilucent, or night-shining, cloud season in the Southern Hemisphere. Scientists analyzed sunspot images from a trio of observatories - including the Big Bear Solar Observatory, which captured this footage - to make the first-ever observations of a solar wave traveling up into the sun's atmosphere from a sunspot. This footage from Hinode's X-ray Telescope is a composite of nearly two months of images, from Aug. 17, 2013, to Oct. 4, 2013.
