Nerdy Engineer: Neil Armstrong on Being a Nerd

An Engineering Manifesto by the first man on the moon. “Science is about what is. Engineering is about what CAN be.”

From “The Engineering Century”, delivered at the National Press Club on February 22, 2000. Audio used with kind permission from the NPC and C-SPAN.

What Space Smells Like

According to many astronauts, space smells like metal and fuel. Other say they’ve picked up notes of grilled meats. When wondering about the smell of space, who better to consult than an astronaut?

Not that they’ve experienced it first hand, either — space is a vacuum, so they would be dead — but they have taken more than a whiff or two of the residue on their space suits.

It’s generally agreed that the aroma is slightly acrid, but not unpleasant. One space traveler even said the scent took him back to the summers of his youth when he worked as an arc welder.

The smell is mostly attributed to dying stars, traces of which are reportedly everywhere — comets, meteors, space dust — you name it. Not only does the aromatic byproduct of the explosions spread, it tends to linger.

The hydrocarbons responsible for the intensity and breadth of space’s olfactory signature are also found in terrestrial products like oil, coal, and some foods.

NASA has commissioned the replication of the smell, so someday we may all get a chance to breathe in some space splendor.

NASA/IBEX Provides First View of the Solar System’s Tail

NASA’s Interstellar Boundary Explorer, or IBEX, recently mapped the boundaries of the solar system’s tail, called the heliotail.

By combining observations from the first three years of IBEX imagery, scientists have mapped out a tail that shows a combination of fast and slow moving particles.

The entire structure twisted, because it experiences the pushing and pulling of magnetic fields outside the solar system.

A Day in the Life of a Fake Astronaut

The Beauty of Space Photography [Off Book - PBS Digital Studios]

Space presents a fantastic mystery to human life. Unfathomably large, with characteristics that defy our experience and understanding, the stars have perplexed and amazed humanity for our entire recorded history, and likely before.

In the present, astrophysicists and astronomers are aggressively studying the universe in an attempt to solve critical scientific and philosophical questions.

One of the primary tools for measurement and observation is imaging using cameras connected to powerful telescopes on Earth and in space. And although it’s not the primary motivation for photographing space, beauty is one of the most intriguing byproducts.

Images of space communicate the grandeur of the universe, and spark essential curiosities about what may be out there waiting for us once we make our way into the stars.

Wringing out Water on the ISS - for Science!

CSA Astronaut Chris Hadfield performed a simple science experiment designed by grade 10 Lockview High School students Kendra Lemke and Meredith Faulkner.

CSA Presents: The Hadfield Shake - Exercise on the ISS

To maintain their bone and muscle mass, astronauts need to work out two hours every day. CSA Astronaut and ISS Commander Chris Hadfield shares his workout routine with us, from cardio on the T2 treadmill, to muscle and bone mass maintenance on the ARED (Advanced Resistive Exercise Device).
