STEREO (Solar Terrestrial Relations Observatory) was launched last October 2006 to provide revolutionary view of the Sun-Earth System. They will capture 3D structure of coronal mass ejections and violent eruptions from the sun. It will mostly helps in space weather detection for the coming of the Earth-directed solar ejections.

The Solar Dynamics Observatory is a more advanced solar spacecraft launched on February 11, 2010 to observe the sun and study the causes of solar variability and its impacts on Earth. It will take a daily detailed images of the Sun by every 0.75 seconds and will send 1.5 terabytes of data back to Earth (the equivalent of 380 full-length movies). It will help scientists understand more of Sun’s magnetic field and how it is released into space as solar wind, energetic particles, and variations in solar irradiance.
