Click. A robot took a final picture of a planetary moon, with the its home colonial planet in the background. There. Its last photo. Time to send it to the masters, it thought as it used the moon’s gravity to go into the stright into the direction of the moon’s orbiting planet.
“Sent Message: A picture of Echo-3, moon file. This is Wonder, contacting for the last time.” Wonder gave what humans could call a sigh. With its artificial intelligence, it scanned for the correct reaction to this situation.
I will die today, it thought. I will crash into Planet Echo and never come back. First I will burn, then be torn apart by gravity. In approximately 2 Earth hours. What to do until then? I suppose I can simply think. Think about life. About what might be on Echo. About how my creators programmed me to die. And how it'll all be over in 2 hours. Hmm. I remember reading something about this. About a robot sent to die along time ago. I wonder how it felt as it crashed into its planet.
The robot turned to look at its own planet as it orbited Echo for the last time. The rays from Sun-2185 swept over the planet, making the water, yes, water, the life giving substance of the universe, shine and turn a terrific dark blue. There were even specks of green on the equator, and the ice caps glowed sapphires and diamonds. Echo really was a beautiful planet, Wonder decided. It had orbited Echo for 27 Earth years, taking pictures, collecting samples, and sending everything it found to its humans on the nearby planet. Wonder knew they were sending probes towards it in a couple of Earth years, to search for life, and it was confident that they would find it. Ding!
“Message received: “Thank you Wonder. For everything. You will be remembered.” Wonder almost chuckled. The humans would remember it, how sweet. Though it doubted that it was true. They sent that message to every robot before they died, at least, that what other robots told it. One hour remaining. What to do, what to do, it thought. I know, how about I search the archives?
Let's see. First memory. A cold lab with several scientists around it, with sounds of excitement and triumph. Then it's first order, take a picture of the ball. It's last moment on the humans’ planet, with the humans frantically waving in excitement. Launching into space, and feeling weightless. Spending Earth months wandering until it finally reached Echo, its purpose. Feeling unique satisfaction every time it took a picture or tested a sample, and feeling pity that humans would never know how great it felt to complete your purpose. Looking at Echo’s two smallest moons for the first time. Getting to name those moons, Wonderland and Wonderful (despite popular belief, Wonder did enjoy the occasional pun). Humans sending its first message (That picture was out of focus. Adjust your camera). Getting to send the message that Echo could have water. Then receiving the humans’ responding message (Holy shit! Water?! Oh my stars!). It's 20th birthday, and receiving a birthday song. Contact with a neighboring robot (Stop contacting me Wonder. I have work to do). And finally, taking its last picture.
That was everything. Well, it had skipped a couple of messages with the neighboring robot, Grateful, who, in a move of irony, was never happy to receive contact or work of any kind.
Two Earth minutes left. Crashing starts now. Wonder moved full speed into Echo’s atmosphere, rushing and feeling the strong gravity latching on to it. Well, no going back now. It gained more and more speed, and the frame began to heat up. Protocol was activated, and it started to shut down. As the edges of its vision turned black, Wonder had one final thought.
“Goodbye humans,” it creaked out loud, “I have completed my purpose. And Echo, you look even more beautiful up close.”
A tribute to Cassini, who crashed into Saturn after 20 years of service to NASA at 6:25 AM EDT, September 15, 2017. Thank you for your contribution to science. You will be remembered.
