Genesis

ResearchCompleted
Jun 30, 2026
Solar orbit | 2001-2004

NASA’s Genesis spacecraft spent more than two years collecting samples of the solar wind. The spacecraft then brought the sample canister back to Earth where it parachuted to the ground. Despite a hard landing in…

GIOTTO

Interplanetary space | 1985-1992

Giotto was ESA’s first deep-space mission. In 1986, it passed closest to the nucleus of a comet, Halley. Its images showed for the first time the shape of a comet nucleus and found the first…

GREECE

Earth polar space | 2014

The purpose of the Ground-to-Rocket Electrodynamics-Electrons Correlative Experiment (GREECE) was to significantly enhance our knowledge of the structure and dynamics of the electron precipitation responsible for the aurora, on both large and small scales, which…

Upper atmosphere | 2026

The Gamma Ray Imager/Polarimeter for Solar flares (GRIPS-2) is a high-altitude balloon payload designed to study particle acceleration and transport in impulsive solar-flares. It flew over Antarctica in January 2016 at a height of 130,000…

ICON

ResearchCompleted
Feb 27, 2026
Low Earth Orbit | 2019-2022

The goal of the Ionospheric Connection Explorer (ICON) mission was to understand the tug-of-war between Earth’s atmosphere and the space environment. In the “no man’s land” of the ionosphere, a continuous struggle between solar forcing…

IMAGE

Completed
Jul 13, 2026
Low-Earth orbit | 2000-2005

The IMAGE spacecraft was launched on 25 March 2000. IMAGE was the first satellite mission dedicated to imaging the Earth’s magnetosphere, the region of space controlled by the Earth’s magnetic field and containing extremely tenuous plasmas…

IMAP

ResearchActive
Jul 27, 2026
Sun–Earth L1 Lagrange Point | 2025-Present

The Interstellar Mapping and Acceleration Probe, or IMAP, explores and maps the very boundaries of our heliosphere — a huge bubble created by the Sun’s wind that encapsulates our entire solar system — and studies…

IMP 1-6

EngineeringResearchCompleted
Jul 20, 2026
Earth orbit | 1963-1971

The Interplanetary Monitoring Platform (IMP) satellites were designed to study the boundary between Earth’s magnetic environment and interplanetary space, along with the radiation – both from the sun and from outside the solar system –…

ISEE-3/ICE

ResearchCompleted
Jul 20, 2026
Magnetotail and lunar space | 1978-1997

NASA’s International Sun-Earth Explorer-3 (ISEE-3) conducted the first deep survey of Earth’s magnetic tail. Then, after a series of complex flybys of the Moon, the spacecraft was renamed the International Cometary Explorer (ICE) and became…

ISI

Research
May 5, 2026
Mount Wilson Observatory

The Infrared Spatial Interferometer (ISI) is a three-telescope interferometric array that uses heterodyne detection at 11 microns wavelength (27 THz). Measurements of the sizes, shapes and changes of red giant stars and their dust envelopes.…
