HESSI -- High Energy Solar Spectroscopic Imager -- or

High Altitude Observatory (HAO), -- dedicated to the study of the Sun and of the response of the Earth's upper atmosphere to the Sun's output. National Science Foundation sponsored laboratory, a division of the National Center for Atmospheric Research

IMAGE also -- The Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) mission is 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 of both solar and terrestrial origin.

May 09, 2002 - EARTH'S SPACE STORM SHIELD OFFERS PROTECTION AT A PRICE -- New observations from a NASA spacecraft reveal that a layer in the Earth's outer atmosphere acts like a heat shield by absorbing energy from space storms, which reduces their ability to heat the lower atmosphere.

National Solar Observatory at or Big Bear Solar Observatory at for solar images in hydrogen-alpha light, or calcium, and more!

Ozone--The POLARIS mission -- seeking to understand the fundamental chemistry that dominates the naturally occuring seasonal reduction of ozone over the pole in the course of the Arctic summer. Part of NASA's Mission to Planet Earth, a long-term, internationally coordinated research effort to study the Earth as a global environmental system.

POLAR mission -- has "sounds" of the magnetosphere.

Solscape -- -- a "Solar Data Browser" Mac application that grabs real time, up to the minute images of the Sun in multiple light wavelengths. Solscape also monitors current solar flare, geomagnetic, and Aurora activity, providing current Aurora Borealis information and warnings for your location, along with real time Aurora images when available. Solscape gets all of its information via the Internet and compiles it in a single, easy to use application. You can save and archive the data that Solscape collects for later use, and you can tell Solscape to automatically grab the data when you want.

Space Weather


    • Advanced Composition Explorer (ACE) - to measure and compare the composition of several samples of matter, including the solar corona, the solar wind, and other interplanetary particle populations, the local interstellar medium (ISM), and galactic matter.

    • Hinode (Sunrise) is a project to study the Sun, led by the Japanese Aerospace Exploration Agency (JAXA) in collaboration with NASA, the Particle Physics and Astronomy Research Council (PPARC), and the European Space Agency (ESA). Hinode's three year mission is to explore the magnetic fields of the Sun, and improve our understanding of the mechanisms that power the solar atmosphere and drive solar eruptions.

    • RHESSI - to understand the following processes that take place in the magnetized plasmas of the solar atmosphere during a flare: Impulsive energy release, Particle acceleration, Particle and energy transport. High Energy Solar Spectroscopic Imager (HESSI).

    • Solar and Heliospheric Observatory

    • Solar Dynamics Observatory (SDO) is designed to help us understand the Sun's influence on Earth and Near-Earth space by studying the solar atmosphere on small scales of space and time and in many wavelengths simultaneously.

    • STEREO consists of two space-based observatories - one ahead of Earth in its orbit, the other trailing behind. With this new pair of viewpoints, scientist will be able to see the structure and evolution of solar storms as they blast from the Sun and move out through space.
