That’s here; that’s home; that’s us—the two bright objects in this picture are Earth and the Moon, imaged by NASA’s OSIRIS-REx spacecraft on January 17, 2018 from a distance of 39.5 million miles (63.5 million km).
This is about the distance between Earth and Mars at their closest points to each other (give or take about 6 million miles) or about 165 times farther away from us than the Moon.
“We came all this way to explore the Moon, and the most important thing is that we discovered the Earth.”
– William Anders, Apollo 8 Commander
On Christmas Eve, December 24, 1968, the Apollo 8 CSM entered orbit around the Moon and, after completing 4 full orbits, provided the three astronauts on board with an amazing sight: a blue Earth rising* beyond the Moon’s cratered limb. Commander Frank Borman spotted the scene first and, after taking a 70mm black-and-white photograph, was able to rotate the Command Module so Earth remained in view through the small windows while CM pilot Jim Lovell captured this famous image on color film. It was the first time any humans saw the Earth from the vicinity of the Moon…and it was also the first Christmas that astronauts spent in space.
“The vast loneliness is awe-inspiring and it makes you realize just what you have back there on Earth,” Jim Lovell said.
Well this is interesting: an article on CNET by Eric Mack, based on a Nov. 27 report from the Russian news agency TASS, discusses findings by Russian cosmonaut Anton Shkaplerov that “living bacteria from outer space” were found within samples collected during spacewalks several years ago (Shkaplerov was a member of Expedition 42 in November 2014.)
The samples were swabbed from outside surfaces of the International Space Station, including areas where engine fuel waste is expelled, and brought back to Earth for study. In addition to some terrestrial bacteria that were accidentally brought to the ISS via contaminated computer tablets, there were also living organisms found that “were absent during the launch of the ISS module.”
“That is, they have come from outer space and settled along the external surface,” Shkaplerov stated. “They are being studied so far and it seems that they pose no danger.”
That’s here; that’s home; that’s us. The image above shows what Earth looked like to NASA’s Cassini spacecraft on April 13, 2017 as it flew past Saturn’s night-shadowed A and F rings. At the time the raw images were captured Saturn and Cassini were about 889.6 million miles (1.43 billion kilometers) from Earth. From that distance our entire world—and everyone on it—is just another tiny light in the dark.
One of the favorite allegations by those who continue to be skeptical of the Apollo moon landings is that there are no stars visible in the photographs taken by the astronauts while they were “supposedly” on the Moon. Now while there’s a rather short but succinct list of why that’s the case (and feel free to review those reasons here) the truth is that there ARE stars visible in photographs taken from the Moon—photographs taken in ultraviolet light during the penultimate Apollo 16 mission in April of 1972.
