The STEREO mission employs two nearly identical space-based observatories - one ahead of Earth in its orbit, the other trailing behind - to provide the first-ever stereoscopic measurements to study the Sun and the nature of its coronal mass ejections (CMEs).
THEMIS answers longstanding fundamental questions concerning the nature of the substorm instabilities that abruptly and explosively release solar wind energy stored within the Earth’s magnetotail.
CINDI's mission is to understand the dynamics of the Earth's ionosphere.
Fifty miles above the ground, Earth's highest clouds form an icy membrane at the edge of the atmosphere. AIM's mission is to study these mysterious Polar Mesospheric Clouds.
Hinode is exploring the magnetic fields of the Sun and is improving our understanding of the mechanisms that power the solar atmosphere and drive solar eruptions.
07.25.08 - NASA’s Interstellar Boundary Explorer (IBEX) spacecraft, designed to image global interactions at the outer reaches of the solar system, today began its move to Vandenberg Air Force Base (VAFB), California.
04.03.08 - The Solar Dynamics Observatory (SDO) spacecraft bus was lowered onto the propulsion module, and it attached on the first try.
03.03.08 - SDO will discover how the sun builds up and explosively releases magnetic energy, which powers severe space weather.
01.02.08 - The Atmospheric Imaging Assembly was delivered to Goddard in preparation for SDO's scheduled launch in December 2008.
11.16.07 - The Helioseismic and Magnetic Imager will gaze through the Sun at internal processes that will help us understand the origins of solar weather.
09.07.07 - SDO's EVE instrument will measure how much the sun's ultraviolet brightness changes.
04.15.08 - NASA is collaborating with the Air Force on an investigation that will study unique plasma bubbles that have the potential to disrupt critical radio signals.
08.20.07 - NASA's two venerable Voyager spacecraft are celebrating three decades of flight as they head toward interstellar space.
03.14.07 - NASA's Aeronomy of Ice in the Mesosphere (AIM) mission, scheduled for launch in April 2007, is the first detailed exploration of Earth's unique and elusive clouds that are literally on the "edge of space."
