Dawn Mission: Scientists Unlock Vesta’s Mysteries

Unlocking Vesta’s mysteries are two of Dawn mission’s participating scientists: Brett Denevi studies Vesta’s regolith, the relatively fluffy surface layer, made of dust and rocky debris leftover by impacts; and Paul Schenk explores Vesta’s craters, especially their weird shapes—often caused by that shifting regolith—and the tales they tell of Vesta’s history! Brett and Paul will show how their investigations of Vesta’s weird and wonderful craters and pits tell the tale of the giant asteroid’s history, as well as share the special role participating scientists have on NASA missions.

Mars Diffracts! X-ray Crystallography and Space Exploration

An epic journey into the role of X-ray diffraction in space!

Astrobiologist and intrepid science communicator Lewis Dartnell reveals the crucial role that x-ray crystallography is playing in understanding the formation and history of our planetary neighbour, Mars.

Explaining the techniques used by the Curiosity Rover to analyse the Martian surface, Lewis reveals what the discovery of clay might mean for the possibility of life on the Red Planet.

Joined by space scientists responsible for designing and operating instruments over 60 million kilometres away, Lewis delves into the mysteries of interplanetary exploration including: How do you design reliable instruments for use on other planets? Should we send humans to Mars? And, what does the next mission to the Red Planet look like?

Featuring instrument scientist Graeme Hansford (University of Leicester) and John Bridges, a participating scientist with the NASA Mars Science Laboratory working on the current Curiosity mission.

This film was supported by the Science and Technologies Facilities Council (STFC).

Journey to Chile’s Wild Islands

In February 2013, National Geographic Explorer-in-Residence Enric Sala led a team of scientists and filmmakers to the Desventuradas Islands off the coast of Chile. What they found there was an abundance of beautiful life and a place in need of protection.

Pristine Seas is a series of expeditions to find, survey, and preserve the last wild places in the ocean. For more information, visit http://www.pristineseas.org.

Will Mars Colonists Go Insane?

Mars One has plans to send human colonists to Mars one day, but if and when those people get to the red planet, will the pressures of being completely cut off from the people they knew on earth drive them insane? Mars One plans to test their candidates likelihood of maintaining sanity in a situation that reads like a Twilight Zone episode. Kim Horcher, Tim Frisch, and Kristen Nedopak (The Geekie Awards) discuss!

Inside the Apollo Lunar Module

Most pictures of the Apollo lunar module show the full, spidery spacecraft from the outside. Some of the best pictures are of it sitting on the surface of the Moon, accidentally but somehow artfully lit by the sunlight reflected off the lunar surface with a space-suited astronaut climbing down the ladder or standing stiffly yet triumphantly by its side. Pictures showing the inside never really give a sense of how big it is. Pictures taken inside simulators using a fisheye lens distort the internal dimensions, pictures of astronauts after surface EVAs focus on the man and not the machine, and pictures of recreated LMs in museums don’t show what it was like filled with gear and manuals.

Exosuit Pushes Limits of Undersea Exploration

With jet thrusters and an aluminum alloy casing, the Exosuit is a submarine you can wear. Later this year, scientists will suit up and plunge 300 meters below the ocean surface to study bioluminescent organisms. Diving safety officer Michael Lombardi of the American Museum of Natural History explains how the Exosuit extends the time a diver can stay submerged at 30 times the surface pressure.
