The Explorers program is a NASA exploration program that provides flight opportunities for physics, geophysics, heliophysics, and astrophysics investigations from space. Launched in 1958, Explorer 1 was the first spacecraft of the United States to achieve orbit. Over 90 space missions have been launched since. Starting with Explorer 6, it has been operated by NASA, with regular collaboration with a variety of other institutions, including many international partners.
Solar physics is the branch of astrophysics that specializes in the study of the Sun. It deals with detailed measurements that are possible only for our closest star. It intersects with many disciplines of pure physics, astrophysics, and computer science, including fluid dynamics, plasma physics including magnetohydrodynamics, seismology, particle physics, atomic physics, nuclear physics, stellar evolution, space physics, spectroscopy, radiative transfer, applied optics, signal processing, computer vision, computational physics, stellar physics and solar astronomy.
The International Solar-Terrestrial Physics Science Initiative is an international research collaboration between NASA, the ESA, and ISAS. Its goal is to study physical phenomena related to the Sun, solar wind and its effects on Earth.
Interstellar Boundary Explorer is a NASA satellite in Earth orbit that uses energetic neutral atoms (ENAs) to image the interaction region between the Solar System and interstellar space. The mission is part of NASA's Small Explorer program and was launched with a Pegasus-XL launch vehicle on 19 October 2008.
Time History of Events and Macroscale Interactions during Substorms (THEMIS) mission began in February 2007 as a constellation of five NASA satellites to study energy releases from Earth's magnetosphere known as substorms, magnetic phenomena that intensify auroras near Earth's poles. The name of the mission is an acronym alluding to the Titan Themis.
The NASA Space Science Data Coordinated Archive (NSSDCA) serves as the permanent archive for NASA space science mission data. "Space science" includes astronomy and astrophysics, solar and space plasma physics, and planetary and lunar science. As the permanent archive, NSSDCA teams with NASA's discipline-specific space science "active archives" which provide access to data to researchers and, in some cases, to the general public. NSSDCA also serves as NASA's permanent archive for space physics mission data. It provides access to several geophysical models and to data from some non-NASA mission data. NSSDCA was called the National Space Science Data Center (NSSDC) prior to March 2015.
Heliophysics is the physics of the Sun and its connection with the Solar System. NASA defines heliophysics as "(1) the comprehensive new term for the science of the Sun - Solar System Connection, (2) the exploration, discovery, and understanding of Earth's space environment, and (3) the system science that unites all of the linked phenomena in the region of the cosmos influenced by a star like our Sun."
Living With a Star (LWS) is a NASA scientific program to study those aspects of the connected Sun-Earth system that directly affect life and society. LWS is a crosscutting initiative with goals and objectives relevant to NASA's Exploration Initiative, as well as to NASA's Strategic Enterprises. The program is managed by the Heliophysics Science Division of NASA's Science Mission Directorate.
Madhulika (Lika) Guhathakurta is an American astrophysicist and scientist with NASA's Heliophysics Science Division. She was the lead program scientist for NASA's Living With a Star initiative and serves as program scientist on the Solar Dynamics Observatory (SDO), Van Allen Probes, and Solar TErrestrial Relations Observatory (STEREO) missions. Lika was previously the program scientist on SPARTAN-201, a free-flying science instrument platform designed to study velocity and acceleration of the solar wind and observe the sun's corona. These missions were conducted as part of the larger STS-56, STS-69, STS-77, STS-87, and STS-95 mission objectives. She has worked as an educator, scientist, mission designer, directed and managed science programs, and has built instruments for spacecraft. Dr. Guhathakurta is known for her work in heliophysics where she has authored over 100 publications on the subject. She served as the NASA Lead Scientist for the North American Solar eclipse of August 21, 2017.
The Heliophysics Science Division of the Goddard Space Flight Center (NASA) conducts research on the Sun, its extended Solar System environment, and interactions of Earth, other planets, small bodies, and interstellar gas with the heliosphere. Division research also encompasses geospace—Earth's uppermost atmosphere, the ionosphere, and the magnetosphere—and the changing environmental conditions throughout the coupled heliosphere.
NASA Heliophysics is an aspect of NASA science that enables understanding the Sun, heliosphere, and planetary environments as a single connected system. In addition to solar processes, this domain of study includes the interaction of solar plasma and solar radiation with Earth, the other planets, and the galaxy. By analyzing the connections between the Sun, solar wind, and planetary space environments, the fundamental physical processes that occur throughout the universe are uncovered. Understanding the connections between the Sun and its planets will allow for predicting the impacts of solar interaction on humans, technological systems, and even the presence of life itself. This is also the stated goal of Science Mission Directorate's Heliophysics Research.
Richard R. Fisher is an American astrophysicist who worked in academia and at NASA. He retired in 2012.
The Interstellar Mapping and Acceleration Probe(IMAP) is a heliophysics mission that will simultaneously investigate two important and coupled science topics in the heliosphere: the acceleration of energetic particles and interaction of the solar wind with the local interstellar medium. These science topics are coupled because particles accelerated in the inner heliosphere play crucial roles in the outer heliospheric interaction. In 2018, NASA selected a team led by David J. McComas of Princeton University to implement the mission, which is currently planned to launch in February 2025. IMAP will be a Sun-tracking spin-stabilized satellite in orbit about the Sun–Earth L1 Lagrange point with a science payload of ten instruments. IMAP will also continuously broadcast real-time in-situ data that can be used for space weather prediction.
NASA's Solar Terrestrial Probes program (STP) is a series of missions focused on study the Sun-Earth system. It is part of NASA's Heliophysics Science Division within the Science Mission Directorate.
Nicola J. Fox is the Associate Administrator for NASA's Science Mission Directorate. Appointed to the position in February 2023, she is therefore NASA's head of science. She was previously the Director of NASA's Heliophysics Science Division. Fox was the lead scientist for the Parker Solar Probe, and served as the Science and Operations Coordinator for the International Solar-Terrestrial Physics Science Initiative.
Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) is a planned orbiter mission tasked to study the origins of the solar wind and how it affects Earth. TRACERS was proposed by Craig A. Kletzing at the University of Iowa who served as Principal Investigator until his death in 2023. David M. Miles at the University of Iowa was named as Principal Investigator in his stead. The TRACERS mission received US$115 million in funding from NASA.
Solar Cruiser was a planned NASA spacecraft that would have studied the Sun while propelled by a solar sail. The mission would have supported NASA's Solar Terrestrial Probes program by studying how interplanetary space changes in response to the constant outpouring of energy and particles from the Sun and how it interacts with planetary atmospheres. It was expected to launch as a rideshare payload alongside IMAP in February 2025. However, the spacecraft was not selected for further development and project closeout efforts concluded in 2023.
Science-Enabling Technologies for Heliophysics (SETH) is a proposed space mission by NASA's Goddard Space Flight Center to launch a small satellite that would demonstrate new technologies to detect solar energetic particles, and demonstrate an optical communication system based on laser pulses.
The Equator-S satellite was a spacecraft constructed by the Max Planck Institute for Extraterrestrial Physics for the International Solar-Terrestrial Physics Science Initiative. It was operational between 2 December 1997 and 1 May 1998.
