Reid Reimers explains one of the often-overlooked technologies that humans need to live in, and explore, space: space suits. Learn about the hundred-year history of the pressurized suit, and see what the future of space couture might look like.

Inflatable Heat Shields Could Drop-Ship Bigger Robots

The Hypersonic Inflatable Aerodynamic Decelerator, or HIAD, is rigorously tested in NASA’s Armstrong Flight Research Center. This technology is being developed to deliver larger payloads to planets more efficiently.

NASA Announces Latest Progress, Upcoming Milestones in Hunt for Asteroids

NASA is on the hunt for an asteroid to capture with a robotic spacecraft, redirect to a stable orbit around the moon, and send astronauts to study in the 2020s — all on the agency’s human Path to Mars. Agency officials announced on Thursday recent progress to identify candidate asteroids for its Asteroid Redirect Mission (ARM), increase public participation in the search for asteroids, and advance the mission’s design.

NASA plans to launch the ARM robotic spacecraft in 2019 and will make a final choice of the asteroid for the mission about a year before the spacecraft launches. NASA is working on two concepts for the mission: the first is to fully capture a very small asteroid in open space, and the second is to collect a boulder-sized sample off of a much larger asteroid. The agency will choose between these two concepts in late 2014 and further refine the mission’s design.

NASA’s Spitzer Space Telescope made recent observations of an asteroid, designated 2011 MD, which bears the characteristics of a good candidate for the full capture concept. While NASA will continue to look for other candidate asteroids during the next few years as the mission develops, astronomers are making progress to find suitable candidate asteroids for humanity’s next destination into the solar system.

Exploring Europa - Ocean Worlds of the Outer Solar System

Where is the best place to find living life beyond Earth? It may be a small, ice-covered moon of Jupiter or Saturn that harbors some of the most habitable real estate in our Solar System. Life loves liquid water and these moons have lots of it! Dr.Kevin Hand, Deputy Chief Scientist for Solar System Exploration at NASA’s Jet Propulsion Laboratory explains the science behind how these oceans exist and what we know about the conditions on these worlds. Dr. Hand focuses on Jupiter’s moon Europa, which is a top priority for future NASA missions and shows how the exploration of Earth’s ocean is helping our understanding of the potential habitability of worlds.

Welcome to the most pristine reefs on the planet

What to know what diving was like long before overfishing, pollution and climate change transformed our oceans? Then you need to feast your eyes on cameraman Stewart Whitfield’s spectacular dive in the pristine waters off the Raja Ampat Islands. No bleaching or dying reefs here — only a big bonanza of tropical marine species and a carpet of every imaginable type of coral.

Smarter Every Day - 116 - Witness to Steve Irwin’s Death

via smartereveryday:

Often very public events are used as news stories without regard to the true human costs involved. Steve Irwin was killed while filming in 2006 by a Stingray. Have you ever stopped to think that there were real people involved in that horrific event? What were the emotional costs? Steve Irwin’s approach to science communication was certainly unique. Some people say he took too many risks and was a bit careless with how he handled himself around deadly animals. Have you ever thought about what a professional scientist would think about Steve’s Actions?

I thought Steve Irwin was awesome.  I wanted to be like him.

My daughter and i dressed up as Steve Irwin and a Crocodile

While diving on the Great Barrier Reef we were using special masks that allow a presenter to use a microphone underwater. I’m a SCUBA diver certified for advanced open water activities, but I was unfamiliar with the equipment so I expressed that to my new dive partner, Dr. Seymour. He reluctantly said “We’ve lost one presenter to the water, don’t worry, I don’t plan on losing another one”. There was something not quite right about how he said it so I pried a bit deeper. That’s how I found out Jamie was on Croc-1 which is where Steve was taken after being hit by the Stingray. He participated in CPR on Steve after only meeting him a few days before. His perspective on the event that shook the world is certainly unique on several levels. After we became friends we agreed that an interview could be done in an intelligent respectful manner, so we did just that. This is the first time he’s spoken publicly about the event. Have a look into the mind of a man who works with deadly animals every day, and see what his thoughts on Steve Irwin were before both before meeting him, and after meeting him. Then try to understand how he has dealt with the event emotionally. https://www.youtube.com/watch?v=twyoQ8LWatU

Sally Ride: Life Stories from the Smithsonian’s Air and Space Museum

The Smithsonian’s National Air and Space Museum in Washington presented a program on Thursday called Sally Ride: Life Stories, about the life and historical impact of America’s First Woman in Space and the history of women entering the astronaut corps. On June 18, 1983, Ride became the first U.S. female astronaut in space when she and her four crewmates launched on STS-7.

Ocean Sampling Day: Take a Sample!

We asked a few students some questions about marine microbes…check out there responses!

Why are we asking? On June 21, NOAA will join scientists around the world in Ocean Sampling Day, an international collaboration to collect water samples from the ocean and rivers. Within the water samples, scientists are looking for marine microbes — tiny living things that make up 98 percent of the biomass in the Earth’s ocean.
