Bruce McCandless II (1937-2017) is immortalized in this iconic photograph of an astronaut flying solo high above Earth. He was the first human being to do a spacewalk without a safety tether linked to a spacecraft.
One of my biggest joys of the winter season is receiving holiday cards from my friends and family. On the other hand, I am terrible about sending cards myself. Imagine being Dick Konter, who had promised over 800 people that he would write to them while on a polar expedition to Antarctica!
Apollo artifacts have begun to receive increased scrutiny in light of recent discussions about returning humans to the Moon and the upcoming 50th anniversary of the historic Apollo missions. What did astronauts of the 1960s and 1970s bring back from the Moon? What was left behind? And how can we verify the authenticity of any of those objects if they have been or will be recovered?
Planetary science is one of those fields of research where you can always count on being surprised. The remarkable terrain of Pluto and Charon in images being sent back by the New Horizons spacecraft certainly qualifies. One of my all-time big surprises is from a recent discovery on an object much closer to home—the Moon.
As we await the exciting results of New Horizons’ flyby of Pluto on July 14, it is all too easy to think that this mission was inevitable: the capstone to NASA’s spectacular exploration of all the planets (and ex-planets) of the solar system since the 1960s. Yet, it proved extraordinarily difficult to sustain a Pluto project.
The first spacewalk by an American, which took place 50 years ago today, marked a new chapter in human exploration of space. Images of Edward White II floating in space with the backdrop of a beautiful blue and white Earth spread a sense of wonder around the world – humans could actually go to this place and it was amazing. While the spacewalk (or EVA, which stands for extra-vehicular activity) lasted less than 20 minutes, its significance for the future of human spaceflight in the American context cannot be underestimated.
