It’s Been 32 Years Since We Last Explored Uranus

Voyager 2 may have been the second of NASA’s famous twin exploration spacecraft but it actually launched first, on August 20, 1977. Eight and a half years later it became the first (and, to date, last) spacecraft to visit Uranus, at 31,500 miles across the third largest planet in the Solar System. Voyager 2 made its closest…

Flying Free: Iconic NASA Astronaut McCandless Has Died

On Feb. 7, 1984, astronaut Bruce McCandless II became the first “human satellite” when he performed the first test flight of NASA’s Manned Maneuvering Unit during STS-41B. Propelled by 24 small nitrogen-powered thrusters, the chair-like MMU allowed McCandless (who helped engineer the Unit at Lockheed Martin) to travel freely through space without any tethers or cords connecting…

Are Alien Bugs Crawling On The Outside Of The ISS?

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…

Watch Ed White Perform the First American Spacewalk, 52 Years Ago Today

Today is the the 52nd anniversary of America’s first spacewalk, performed by NASA astronaut Edward H. White II on the afternoon of June 3, 1965 during the four-day Gemini IV mission. In NASA terminology spacewalks are also referred to as extravehicular activities, or EVAs—basically anything done outside the protection of a spacecraft. The video above shows footage…

What Would Happen to You if You Were Exposed to Space?

We’ve all seen it in some form or another in science fiction movies: a character suddenly finds themself exposed, sans protective suit, to the vacuum of space. Maybe it was a crack in their suit or helmet, or they were caught in an open airlock, or they were sucked out of a hole in a spacecraft…

Take a Ride with Alan Shepard Aboard Freedom 7

On this day in 1961, May the 5th at 9:34 a.m. Eastern time, NASA astronaut Alan B. Shepard, Jr. became the first American to travel into space with the launch of his Freedom 7 vehicle atop a Mercury-Redstone rocket. Shepard reached an altitude of 116.5 miles during his 15-minute suborbital flight before splashing down in…

Voyager 1’s Famous Long-Distance Valentine

If you’re in love with space then you’ll fall head over heels for this: it’s a picture of Earth taken from the Voyager 1 spacecraft after it passed the orbit of Pluto back in 1990—on Valentine’s Day, no less. That image of our planet from almost 4 billion miles away inspired Carl Sagan to write his famous…

Seeds From Space: The Moon Trees of Apollo 14

On Feb. 9, 1971, Apollo 14 astronauts Alan Shepard, Jr., Stuart Roosa, and Edgar Mitchell returned to Earth, their command module Kitty Hawk splashing down in the Pacific Ocean at 21:05 UT (4:05 p.m. EST). They were recovered by the USS New Orleans (LPH-11) and returned to the U.S. by way of American Samoa. But the…

A Heck of a Leap: When Bruce McCandless Became the First Human Satellite

On Feb. 7, 1984, NASA astronaut Bruce McCandless II became the first “human satellite” when he tested the Manned Maneuvering Unit during STS-41B. Propelled via 24 small nitrogen-powered thrusters, the MMU allowed McCandless (who was instrumental in developing the Unit at Lockheed Martin) to travel freely through space. In the iconic photo above McCandless is seen floating against…
