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.

Best Evidence Yet For Coronal Heating Theory Detected by NASA Sounding Rocket

Best Evidence Yet For Coronal Heating Theory Detected by NASA Sounding Rocket

08.01.14 – Scientists have recently gathered some of the strongest evidence to date to explain what makes the sun's outer atmosphere so much hotter than its surface. The new observations of the small-scale extremely hot temperatures are consistent with only one current theory: something called nanoflares - a constant peppering of impulsive bursts of heating, none of which can be individually detected — provide the mysterious extra heat.
