HESSI is Off!
News story originally written on February 6, 2002
The HESSI spacecraft was supposed to be launched a long time ago. But, several problems
stopped that from happening. The important thing is that HESSI was launched on February 5, 2002, and the mission is going well so far.
HESSI is the name of NASA's newest satellite built to study the Sun. HESSI stands for High Energy Solar Spectroscopic Imager. Those big words mean that HESSI will study solar flares. Solar flares are high energy and they can have big effects on the Earth!
