Mike Libecki & Cory Richards: Antarctic Mountain Climbing
Accomplished climber Mike Libecki and photographer Cory Richards battle extreme cold and furious katabatic winds in an epic, ten-day climb to the summit of the untouched Bertha’s Tower at the bottom of the world.
Life On Mars Sim: Extracting Fuel Making Hydrogen From ‘Mars’ Soil
MarsCrew134’s crew scientist Vibha Srivastava describes extracting hydrogen fuel from soil sampled outside a simulated Mars habitat in Utah, a process called “in-situ resource utilization.”

Human Eyes in Orbit Swell & Change Shape: Space-Sightedness
NASA studies of microgravity effects on vision have found that tissue at the back of the eyes swells and distorts in shape. This causes both nearsightedness and farsightedness for astronauts.

Life On Mars Sim: ‘Terraforming’ Utah To Grow On Mars
MarsCrew134 is simulating the exploration of Mars in high altitude Utah. Crew scientist Michaela Musilova is adding organisms from Earth’s extreme environments to the Utah soil samples to create organics, and important step in terraforming Mars.

Forget Mars, the place we really want to go looking for life is Jupiter’s moon Europa. Dr. Mike Brown, a professor of planetary science at Caltech, explains what he finds so fascinating about this icy moon, and the potential we might find life swimming in its vast oceans.

Opportunity: 10 Years on Mars - Science
Two Mars Exploration Rovers, Spirit and Opportunity, landed on the Red Planet in January, 2004, on a 90-day mission. Spirit’s mission lasted 2,269 days (over 6 years) and ended in 2010. Ten years after landing, the Opportunity rover continues to explore. The rover’s science team explains how Opportunity traversed the Red Planet, examined the diverse environment and sent back data that transformed our understanding of Mars.
Opportunity: 10 Years on Mars - Operating A Rover
There are no vehicle repair stations on Mars. The Opportunity rover landed on the Red Planet in January 2004 for a 90-day mission. Ten years later it’s still going strong despite not being serviced by human hands in over a decade. The engineering team discusses the demands of driving a rover millions of miles away, keeping it alive in the extreme Martian elements and doing long-distance repairs.
Cloudy With A Chance Of Aliens: How We Look for Extraterrestrial Life
What do astronomers look for when they study exoplanets for signs of alien life? Hank explains how space telescopes are already yielding tantalizing clues of what other worlds might hold — including water! — and how the next generation of technology will be able to reveal to us.
It Happened In Space №14 - Apollo and the Saturn IB Rocket
The Saturn IB rocket was vital to the Apollo era, launching the first manned mission of the lunar landing program, all three Skylab missions, and the Apollo half of the Apollo-Soyuz mission.

Chasing comets in space
Space missions have been chasing comets since the launch of the Giotto spacecraft in 1985. NASA’s Stardust mission flew through a comet’s tail in 2006 and brought a sample of dust back to Earth. Glycene was found in this sample, one of the four basic amino acids in our DNA. We can make a fake comet on Earth using a recipe of water ice, liquid nitrogen and fine carbon particles. By testing the fake comet and simulating the conditions of space, this will help scientists interpret data from ESA’s latest comet chaser - Rosetta. With ESA’s comet chaser Rosetta expectations are great : for the first time a probe will be flying alongside a comet and even placing a lander on its surface.
The Countdown №41 - 5 Everyday Products Developed from NASA Technology
NASA is known for hi-tech wizardry when it comes to spacecraft, but some of its technology has floated back down to earth and made it into objects we use everyday. Here are five that surprised us!

Dynamic Mars from Long Term Observations
There has been a continual spacecraft presence at Mars since 1997. The longevity of spacecraft missions examining the Red Planet has enabled detection and examination of changes on multiple time scales. Active processes include planet-encircling dust storms about every three to four Mars years, evolution of the polar caps, fresh impacts, migrating sand, and a suite of processes on slopes, some of which may involve liquid water. The distribution of shallow ice is much better known, with implications for recent climate change. The longer the observations continue, the deeper the understanding grows about active processes on Mars.
Death in Space
How accurate was the depiction of death in space in the movie, “Gravity”? Does NASA have protocols if an astronaut dies in space? Is it a case of “no body left behind” or do they launch the body into space like Spock in “Star Trek II: The Wrath of Khan”? The answers might surprise you in this morbid, but informative Cosmic Query featuring guest host NASA astronaut Astro Mike Massimino and co-host Chuck Nice.
