Black-and-White Vintage NASA Photographs

May 28th, 2013 | Space

Vintage NASA Photographs

NASA was officially created on October 1st, 1958 to “provide for research into the problems of flight within and outside the Earth’s atmosphere, and for other purposes.” However, space and aeronautics research was being conducted for several decades before NASA’s inception under the guidance of NACA, the National Advisory Committee for Aeronautics.

The images seen here are just a sample of the gorgeous photographs taken during the infancy of the United States Space Program.

The United States had a clear goal — beat the Russians the Moon — and in 1969, we succeeded. However, I can’t help but feel our space program has been a bit lost ever since…

The Saturn Rose

Saturn Rose

The Saturn Rose

Located directly over Saturn’s North Pole is a GIANT hurricane measuring around 1,250 miles  (2,000 kilometers) across with cloud speeds reaching 330 mph (150 m/s).  That is about 20 times bigger than the average hurricane here on Earth!  Another interesting difference is that it doesn’t seem to move around at all.  NASA stated that “the hurricane swirls inside a large, mysterious, six-sided weather pattern known as The Hexagon.”   They went on to say that it has likely been spinning in the same location for years, but no one really knows why…

The image above was shot from the Cassini spacecraft which has been cruising around Saturn taking photos of the planet and its moons since 2004.  The hurricane has apparently been obscured by a long winter in the north pole, but the seasons have shifted, and we have recently gained enough light to see the beast in all its glory.

Here’s how the image was taken:

“The images were taken with the Cassini spacecraft narrow-angle camera on Nov. 27, 2012, using a combination of spectral filters sensitive to wavelengths of near-infrared light.

The images filtered at 890 nanometers are projected as blue.

The images filtered at 728 nanometers are projected as green, and images filtered at 752 nanometers are projected as red. In this scheme, red indicates low clouds and green indicates high ones.”

In other words, they used false colors to show low clouds in red versus high clouds in green.  What an amazing solar system we have…

Wringing out Water (In Space)

Wringing-out-Water-In-Space

International Space Station Commander Chris Hadfield is renowned for his communication of science. He plays guitar from space, throws up incredible images of Earth from the ISS, and he’ll answer all your curiosities about living in a gravity-free world on YouTube.  This recent demonstration was a result of a question from 2 high school students, Kendra Lemke and Meredith Faulkner, who were interested in what might happen when you wring out water from a washcloth in space.

The result is pretty amazing.  I was worried the water would short-circuit the electronics, but thanks to surface tension, all is well.

Ninja Star Supersonic Plane

September 5th, 2012 | Robot, Space

NASA may be most known for its space exploration, but the organization also makes significant contributions to technology back here on Earth.  0,000 was recently awarded to The University of Miami team responsible for the Ninja Star Supersonic plane shown above.

The really interesting thing about the plane is that it can fly in 2 different orientations.  One direction is specifically designed for normal, sub-sonic flight speeds, but with a quick turn of 90 degrees, it can zoom into Supersonic speed without the loud Sonic BOOM.  AND, they say this plane could get you from New York to Tokyo in 4 hours!

You can see the normal, sub-sonic orientation below.

And although the aircraft is officially called the supersonic bi-directional (SBiDir) flying wing (FW), I’ll put my vote in for The Ninja Star when it comes out in about 20 years.

Curiosity’s Descent onto Mars (in HD)

August 23rd, 2012 | Space

In case you missed it, NASA landed a new rover by the name of Curiosity onto the surface of Mars back on August 6th. Daniel Fitch, of YouTube, recently compiled a set of High-definition images taken by the Mars Descent Imager to make the video seen above.

At first, you see the heat shield being ejected toward the surface.  Once the shield is gone, the rover’s radar is revealed to calculate the right speed and direction of descent which can be controlled with its jetpacks.

Now, we just have to sit back and let the rover roam the Red Planet and try to achieve its 4 goals:

Goal 1: Determine whether life ever arose on Mars

Goal 2: Characterize the climate of Mars

Goal 3: Characterize the geology of Mars

Goal 4: Prepare for human exploration

I’m most excited about Goals 1 & 4.  Send Humans!

ISS Star Trails

ISS Star Trails 1

These are some pretty awesome time lapse photos taken from the International Space Station by Flight Engineer, Don Pettit.  Here’s an excerpt from the photographer:

“My star trail images are made by taking a time exposure of about 10 to 15 minutes. However, with modern digital cameras, 30 seconds is about the longest exposure possible, due to electronic detector noise effectively snowing out the image.

To achieve the longer exposures I do what many amateur astronomers do.

I take multiple 30-second exposures, then ‘stack’ them using imaging software, thus producing the longer exposure.

You would think he might be able to get his hands on a long exposure camera, but oh well, these turned out great.
