Gratitude towards things that serve us well

Sometime in 2004, the twin exploration rovers named “Spirit” and “Opportunity” were sent to Mars to search for evidence of water and life on Mars. Both rovers lived well beyond their planned 90-day missions. “Spirit” lasted 20 times longer than its original design. “Opportunity” worked nearly 15 years on Mars. They faithfully sent images that gave scientists the story of that planet’s watery past. So it’s not surprising that those vehicles were considered as “family” by their NASA operators and played “wake-up” songs to the two rovers as they went on with their tasks. Even the public got invested in their success and developed an affection for them. Sad to learn that they are no longer roaming around Mars.
