The great PBS science series Nova scores another hit with Mars: Dead or Alive, capturing all the excitement surrounding the Mars rover landings of early 2004.Originally broadcast just as the first of the twin rovers (“Spirit” and “Opportunity”) was experiencing temporary communication problems with Earth-bound mission controllers, this riveting hour-long episode chronicles the risky $820 million
Millions remember the countdowns, launchings, splashdowns, and parades as the U.S. raced the USSR to the moon in the 1960s. But few know that both countries also ran parallel space programs, whose covert goal was to launch military astronauts on spying missions. In this program, NOVA delves into the untold story of this top-secret space race, which might easily have turned into a shooting war in o
Lawrence Krauss gives a talk on our current picture of the universe, how it will end, and how it could have come from nothing.Krauss is the author of many bestselling books on Physics and Cosmology, including “The Physics of Star Trek.”If you’ve ever wanted to answer that annoying question, “how could the Universe have formed from nothing”, then watch this video.Lawrence Krauss is funn
The Phoenix Lights (sometimes referred to as the “lights over Phoenix”) were a series of widely sighted optical phenomena (generally unidentified flying objects) that occurred in the skies over the U.S. states of Arizona and Nevada, and the Mexican state of Sonora on March 13, 1997. A repeat of the lights occurred February 6, 2007, and was filmed by the local Fox News TV station. A similar inciden
Think about this: to date, only three countries have been able to put a man merely in Earth orbit – the United States, Russia, and China. That speaks to how difficult it is just to get into orbit. Next, consider how far away the moon is from the Earth: 240,000 miles. Since the alleged moon landings, no country even claims to have gone more than 400 miles from Earth and that was in the Space Shuttl
The earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that in glory and triumph, they can become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on this scarcely distinguishable inhabitants of some other corner. How frequent their misunder
In the far corner of our solar system, orbiting quietly, lurks one of the biggest threats to the survival of the human species. Somewhere out there, there’s an asteroid with our name on it. The Earth is under constant bombardment. Each year, many fragments of debris hit our planet. Fortunately for us, most are so small that they burn up harmlessly in the atmosphere. However , there are hundreds
With Cosmos, Carl Sagan and his wife and co-writer, Ann Druyan, brilliantly illustrated the underlying science of his same-titled book, placing the human species within a space-and-time context that brought the infinite into stunningly clear view. The series, which originally aired in 1980 on PBS, has been seen by more than 700 million people worldwide and remains a high-water mark in miniseries h
