The Apollo 11 astronauts returned from the moon 40 years ago today, but they left behind more than footprints. An experiment they placed on the moon?s surface is still running to this day.Fantastic feat from NASA. Well done.
I have a question - that previous elongated flat rock object that came into our solar system a couple of months ago, why don't they plant a spacecraft like U.T. (see what I did there!) on one of those objects and allow it to ride it around its orbit? Or stick something on the moon to monitor the earth ?
In this animated GIF of Kuiper Belt object Ultima Thule made from two images taken 38 minutes apart, the "Thule" lobe is closest to the New Horizons spacecraft. As Ultima Thule is seen to rotate, hints of the topography can be perceived. The images were taken by the Long-Range Reconnaissance Imager (LORRI) at 4:23 and 5:01 Universal Time on January 1, 2019 from respective ranges of 38,000 miles (61,000 kilometers) and 17,000 miles (28,000 kilometers), with respective original scales of 1017 feet (310 meters) and 459 feet (140 meters) per pixel.
