SDO will study how solar activity is created and how Space Weather comes from that activity. Measurements of the interior of the Sun, the Sun's magnetic field, the hot plasma of the solar corona, and the irradiance that creates the ionospheres of the planets are our primary data products.
The Magnetospheric Multiscale (MMS) Mission will use four identical spacecraft, variably spaced in Earth orbit, to make three-dimensional measurements of magnetospheric boundary regions and examine the process of magnetic reconnection. Scheduled to launch in 2014.
Interstellar Boundary Explorer (IBEX) mission's science objective is to discover the nature of the interactions between the solar wind and the interstellar medium at the edge of our solar system.
High Energy Solar Spectroscopic Imager (RHESSI)'s primary mission is to explore the basic physics of particle acceleration and explosive energy release in solar flares.
Solar Terrestrial Relations Observatory (STEREO) consists of two space-based observatories - one ahead of Earth in its orbit, the other trailing behind. With this new pair of viewpoints, scientists will be able to see the structure and evolution of solar storms as they blast from the Sun and move out through space.
The Solar & Heliospheric Observatory, SOHO-is a project of international collaboration between ESA and NASA to study the Sun from its deep core to the outer corona and the solar wind.
Hinode is an international mission to study our nearest star, the sun. To accomplish this, the Hinode mission includes a suite of three science instruments.
Radiation Belt Storm Probes (RBSP) is being designed to help us understand the Sun's influence on Earth and Near-Earth space by studying the Earth's radiation belts on various scales of space and time. Will launch in September 2012.
NASA mission to discover planets around other stars by the transit method. Education section has a wealth of activities, models, online interactives, resources, and a planetarium show.
Resources on the history of the telescope.
Carrying six high-resolution sensors and three monitoring instruments samples low-energy particles of solar origin and high-energy galactic particles with a collecting power 10 to 1000 times greater than past experiments.
The primary objective of LRO is to conduct investigations that prepare for future lunar exploration.
The Interstellar Mission- The mission objective of the Voyager Interstellar Mission (VIM) is to extend the NASA exploration of the solar system beyond the neighborhood of the outer planets to the outer limits of the Sun's sphere of influence.
CINDI seeks to discover how the neutral gas motions and the charged particle motions are related.
Solar flares can sometimes heat the solar surface to temperatures of 80 million °F - far hotter that the sun's core!
