NASA launched first weather mission into space by the experiment Extreme Ultraviolet Variability Experiment (EVE). The weather mission is called as Solar Dynamics Observatory (SDO). The SDO successfully separated from the booster rocket about one hour and 48 minutes after launch. This weather mission helps to understand the sun and its effects on society. NASA missed this launch three times due to the bad weather conditions.
Solar Dynamics Observatory will send about 1-5 terabytes of data to earth each day and delivers the solar images of sun with ten times better resolution. SDO determines how the sun’s magnetic field is generated, structured, and converted into violent solar events. The violent solar events include turbulent solar wind, solar flares, and coronal mass ejections (CME’s). The solar wind is electrically charged particles and the solar flares are explosions in the sun atmosphere. CME’s are eruptions that launch solar material into space.
The violent solar events can put the astronauts at risk. The SDO provides the awareness regarding dynamics of the sun and also alerts the satellites or airline operations and department of defense system. The major instruments of SDO are helioseismic, magnetic imager and the atmospheric imaging.
