HESSI is Go for Launch!
News story originally written on January 9, 2002

The HESSI spacecraft was supposed to be launched a long time ago. But, HESSI has had a hard time getting off the ground because of several problems. HESSI will hopefully be launched on January 24, 2002.

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!
