Space Mission Concludes After Nearly Seven Years
A space mission, initially designed for a two-year operational period, concluded after operating for nearly seven years. The mission's end was attributed to the depletion of its spacecrafts' fuel supply, which prevented them from orienting towards the Sun.
Mission Duration and Conclusion
The mission, which surpassed its original operational plan by approximately five years, ceased operations following the complete exhaustion of its onboard fuel reserves. This depletion resulted in the spacecrafts' inability to maintain proper orientation, specifically towards the Sun.
