Mars Rover ‘Opportunity’ Seen From Orbit

March 10, 2011 Leave a comment

I thought this was pretty cool.

The Mars Exploration Rover ‘Opportunity’ was captured in this image from the Mars Reconnasaince Orbiter while it was studying a crater.

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter acquired this color image on March 9, 2011, of "Santa Maria" crater, showing NASA's Mars Exploration Rover Opportunity perched on the southeast rim. - Image Credit: NASA/JPL-Caltech/Univ. of Arizona

Opportunity has been working on Mars since 2004, even though its initial mission length was only supposed to be 3 months.

Pretty damn impressive if you ask me.

Minnesota Blizzard From Spaaaaaaace!

On Saturday December 11, 2010 over 40 cm of snow fell in the Minnesota area. NASA’s Terra satellite captured this awesome image of the snow.

This is the same storm that caused the Metrodome, home of the Minnesota Vikings to collapse.

This forced the Vikings to play their game in Detroit. It didn’t work out so well for them…

The Hungary ‘Sludge’ Spill From Space

October 12, 2010 Leave a comment

About 8 days ago, a waste-retaining pond at an alumina oxide (aluminium ‘rust’) plant in Hungary broke and released about 700 000 cubic meters of toxic sludge into the nearby towns of Kolontar and Devecser.

On October 9, the Advanced Land Imager on NASA’s Earth Observing-1 satellite captured this natural-color image of the area.

Pretty remarkable. The sludge itself is obviously visible as the dark brown colour. You can also easily make out the two nearby towns being contaminated.

It must have incredibly terrifying when it happened. This is what a resident of Kolontar said:

The sludge took our car, lifted it up and took it along… We found it the next day about a mile and a half away.

The worst hit areas had a pH of 13.5, roughly the same as bleach. The pH level has fallen to around 8 in the past few days, but the area remains extremely toxic.

Colorado Wildfires in Pictures

On Monday (Sept. 6) a wildfire erupted in Colorado, near the city of Boulder.

3500 people have been evacuated from their home, and more evacuations are possible. 92 structures, including residential homes, have also been destroyed.

We hear about wildfires almost every year, and those of us who live far away from large forested areas don’t really get a sense of the magnitude of these fires.

To help, here are a couple of photos. The first two are from NASA’s AQUA satellite

The other photo hits a bit closer to home. Pretty amazing sight. Hopefully some wet weather will hit soon.

Hurricane Earl and My House in the Same Photo!

September 2, 2010 Leave a comment

I know I’ve done a post about hurricane Earl already, but this is just too cool not to mention.

This visible light photo was taken by the Atmospheric Infrared Sounder (AIRS) satellite yesterday, and boy is it cool.

You can see the hurricane (obviously) but what makes it so cool to me is that you can see all of southern Ontario and the great lakes. Right where I grew up!

Never thought I’d seem my hometown and a hurricane in the same picture before. Awesome!

NASA Flies Plane Into Hurricane Earl

NASA, in its ongoing effort to study just about, well, everything, has outdone themselves this time.

They flew a DC-8 into Hurricane Earl in an effort to study how hurricanes and tropical storms form. SWEEEET!

They also got this really cool satellite image of Hurricane Danielle (northern one) and Hurricane Earl (southern one) in the same image.

Hurricane Katrina As Seen From Space: 5 Years Later

August 26, 2010 Leave a comment

Its been almost 5 years since the disaster of Hurricane Katrina.

The city of New Orleans has not yet fully recovered from the devasting effect of the hurricane, which made landfall in the United States on August 29, 2005, and the failure of the levees which were supposed to protect the historic city.

As a way of reminding us all of the terrible impact the hurricane had, NASA has released this retrospective video. It contains images and analyses from a wide variety of satellites which imaged the hurricane as it developed, travelled through the Gulf of Mexico, hit the city of New Orleans, and finally it shows the amount of flooding which occured after the hurricane hit.

From a scientific standpoint, it is very interesting to see how the hurricane progressed in its development. Unfortunetly, the images of those trapped on rooftops are still burned into my memory, so the knowledge gained from studying this hurricane is somewhat bittersweet.

Our Glorious Planet: As Seen From Mercury

I never ceases to amaze me just how massive the universe is.

Take for example, this photo of the Earth and our moon, taken from roughly 114 million miles away.

Click on the image to wonderfully aggrandize (thank you

The image was taken from a NASA mission called MESSENGER (MErcury Surface, Space ENvironment, GEochemistry and Ranging). MESSENGER was launched in 2004 and has done 3 flybys of Mercury, on its way to be in a permanent orbit to study the planet in 2011.

It is truly humbling to see our planet as a tiny speck in the vastness of space.

As Carl Sagan would say: “One voice in the cosmic fugue.”
