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…

On This Day in 1966 We Got the First Picture from the Moon

On Feb. 3, 1966 the Soviet Luna 9 spacecraft made the first successful robotic soft landing on the Moon. Seven hours later it transmitted its first images of the lunar surface back to Earth. The image above is Luna 9 lander’s first view—the first time humans had ever seen a picture from the surface of another world.

Asteroid 16 Psyche Could Truly Be a Psychedelic Little World—AND Worth Quadrillions

NASA recently announced the go-ahead for a new Discovery-level mission that would send a spacecraft to explore 16 Psyche, a 130-mile-wide asteroid in the Solar System’s main belt between Mars and Jupiter. 16 Psyche is a relatively small world but is made almost entirely of metals—some of them what we’d consider precious on Earth, like nickel, gold, and…

Plutonium is Back on the Menu, Future NASA Missions!

While I highly advise against humans making a meal out of it (despite my headline) the radioactive element plutonium has long been a staple energy source for many of NASA’s space missions, from Apollo’s ALSEPs to the twin Voyagers to the Curiosity rover.* But the particular non-weapons-grade flavor that NASA needs — plutonium dioxide, aka Pu-238 — has not been…

Here’s to 50 Years of American Spacewalks

Today we mark the 50th anniversary of American spacewalks, or EVAs (for extra-vehicular activity), the first of which was performed by NASA astronaut Edward H. White II in Earth orbit on June 3, 1965 during the Gemini IV mission. While the United States had been beaten in the spacewalk race by the Soviet Union by almost three months…

Could Humans Set Up Camp in Martian Lava Tubes?

The concept of off-world habitation has been getting extra attention recently, especially with the announcement of 100 semi-finalists selected for the MarsOne “mission” (quotes because there’s more than a small amount of doubt that it will ever really take off – pun intended) and world-famous astronauts like Buzz Aldrin unabashedly telling us to “get our asses…

This Is the First Color Image from the Surface of Venus

The surface of Venus is definitely no easy place to which to send a spacecraft. Crushing atmospheric pressures, powerful high-altitude winds amid caustic clouds of sulfuric acid, and temperatures that can soar above 880ºF (475ºC) make the next planet in a no-man’s-land for robotic spacecraft. But those challenges didn’t stop the Soviet space program from successfully putting several…
