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.

NASA Selects Proposals to Study Neutron Stars, Black Holes and More

07.30.15 – NASA has selected five proposals submitted to its Explorers Program to conduct focused scientific investigations and develop instruments that fill the scientific gaps between the agency's larger missions.

The selected proposals, three Astrophysics Small Explorer missions and two Explorer Missions of Opportunity, will study polarized X-ray emissions from neutron star-black hole binary systems, the exponential expansion of space in the early universe, galaxies in the early universe, and star formation in our Milky Way galaxy.
