TC-1 |
The 'equatorial' spacecraft (TC-1) was launched into an elliptical orbit on December 29, 2003. This enables it to investigate the Earth's huge magnetic tail, the region where particles are accelerated towards the planet's magnetic poles by a process known as reconnection. TC-1's nominal period of operations is expected to exceed 18 months (ref: NORAD data).
