What did Neil Armstrong really say when he took his first step on the moon? Millions on Earth who listened to him on TV or radio heard this: “That’s one small step for man, one giant leap for mankind.”
During training for Armstrong’s second and last spaceflight as commander of Apollo 11, he had to eject from the Lunar Landing Research Vehicle moments before a crash….

US astronaut Neil Armstrong, the first man on the Moon, has died aged 82. A statement from his family says he died from complications from heart surgery he had earlier this month. He set foot on the Moon on 20 July 1969, famously describing the event as “one small step for a man, one giant leap for mankind”.
A total of 18 people have lost their lives either while in space or in preparation for a space mission, in four separate incidents. In 2003 a further seven astronauts died when the shuttle Columbia broke up on re-entry into Earth’s atmosphere. …
As a result NASA’s official policy forbids pregnancy in space. Female astronauts are tested regularly in the 10 days prior to launch. And sex in space is very much frowned upon.
Space Is Dark, But Scientists Have Found Unexplained Light : NPR. Space Is Dark, But Scientists Have Found Unexplained Light Scientists have used a NASA probe way out in space, beyond Pluto, to measure visible light that’s not connected to any known source such as stars or galaxies.
Far and away the brightest object in the sky, the sun is easy to find, but it’s so bright that one can’t look directly at it without vision damage. Unlike most satellites, which orbit the Earth, SOHO orbits around the sun itself, like a planet or comet.
Of course we can see stars in space. We see stars more clearly from space than we do from Earth, which is why space telescopes are so useful. Even in space the stars aren’t overly bright, and our eyes can lose dark adaption pretty quickly. NASA An image from the ISS of stars and glowing layers of Earth’s atmosphere.
The Great Wall of China, frequently billed as the only man-made object visible from space, generally isn’t, at least to the unaided eye in low Earth orbit. It certainly isn’t visible from the Moon. You can, though, see a lot of other results of human activity.
Proxima Centauri
30 billion light-years away
The moon is a difficult target for Hubble because it moves across the sky faster than Hubble can track it and is very dim in ultraviolet light. The observations required steady, precise, as well as long exposures to search for the resources.
Canis Major Dwarf Galaxy
At the rate of 17.3 km/sec (the rate Voyager is traveling away from the Sun), it would take around 000,000 years to reach this distance. At the speed of light, it would take 13 billion years!
So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.
