The Panama Canal from Space – A collection of satellite images before and after the Expansion Project

In commemoration of completion of the Panama Canal Expansion Project, and in tribute to the upcoming official opening on June 26, we present a series of before and after satellite photos highlighting the Expansion Project and showcasing this engineering marvel.

Work on the Panama Canal Expansion took nearly 9 years to complete, starting in September 2007, at a cost of US$5.2 billion. By adding a third set of locks on both the Pacific and Caribbean sides of the canal, dredging the existing navigation channel, adding a new approach channel on the Caribbean side and a new 6.1 km access channel on the Pacific side, and raising the Gatun Lake maximum operating level, the Expansion doubles the capacity of the Canal and significantly increases the size of vessels that can transit the Canal.

Below we present before and after satellite images of the newly expanded Canal, provide an overview of the Expansion Project, show a rare nearly-cloudless image from Landsat-5, and even include one of the earliest Landsat images of the Panama Canal acquired by Landsat-1 on March 18, 1973.

Note the addition of the third set of locks, the three sets of water reutilization basins immediately adjacent to the new locks, and the new access channel that now bypasses Miraflores Lake.

For the remote sensing history aficionados, this is the earliest Landsat image of the Panama Canal listed in the USGS archives, from Landsat-1 on March 18, 1973, over 40 years ago.

Astronaut Photography – Your access to stunning views from space

Astronauts have busy schedules in space – system operations, maintenance, repairs, science experiments – but did you know they also acquire hundreds of photos during each mission?

Reid Wiseman , Astronaut Photography

From stunning views of Earth’s natural features to glimpses of your favorite city at night, and from pure artistry to applied science, these photos offer a remarkable perspective of our planet’s surface as well as a valuable historical record of how and where our planet is changing.

There are now two great resources available for viewing this photography:

Both websites provide access to thousands of photos, are free to use, allow users to search photos or browse by category, and even provide options to download images for your own use (but be sure to read through the conditions of use on both websites).

We’ve spent countless hours browsing through these stunning image collections, and encourage you to take a look for yourself.

We hope you enjoy!

Gateway to Astronaut Photography of Earth

“The Gateway to Astronaut Photography of Earth hosts the best and most complete online collection of astronaut photographs of the Earth from 1961 through the present. This service is provided by the International Space Station program and the JSC Earth Science & Remote Sensing Unit, ARES Division, Exploration Integration Science Directorate.” – http://eol.jsc.nasa.gov/

Windows on Earth

“Windows on Earth is an educational project that features photographs taken by astronauts on the International Space Station.  Astronauts take hundreds of photos each day, for science research, education and public outreach.  The photos are often dramatic, and help us all appreciate home planet Earth. The site is operated by TERC, an educational non-profit, in collaboration with the Association of Space Explorers (the professional association of flown astronauts and cosmonauts), the Virtual High School, and CASIS (Center for Advancement of Science in Space).” – http://www.windowsonearth.org/

The “White Stork” Makes a CubeSat Delivery – ISS receives four new micro-satellites

ISS HTV-4

Earlier this month on August 3, 2013 the Japanese H-II Transfer Vehicle-4 (HTV-4) was launched from the Tanegashima Space Center in southern Japan. The HTV, nicknamed “Kounotori” (White Stork), is an unpiloted spacecraft used to resupply the International Space Station.

In addition to supplies and other research cargo, the recent HTV-4 mission included four new CubeSats:

  • Pico Dragon. This is a 1U CubeSat developed by the Vietnam National Satellite Center. Its mission is to acquire images of the Earth, collect space environment data, and test satellite communication systems.
  • Ardusat-1 and Ardusat-X. These are 1U CubeSats created by NanoSatisfi, with development partially funded through a crowdfunding campaign on KickStarter. The ArduSat satellites provide open-source Arduino platforms for users to control onboard instruments and perform their own space-based experiments.
  • TechEdSat-3. This is a 3U CubeSat collaboratively built by San Jose State University and the University of Idaho with guidance from NASA Ames Research Center. This satellite is being used to test exo-brake technology for passive de-orbiting of satellites and other payloads.

CubeSats offer a low-cost option for deploying and testing new space technologies and for encouraging research in space science. Given their small size – a 1U CubeSat is a 10cm cube – the satellites can be readily deployed as opportunistic payloads on larger missions. They can also be easily designed to burn up upon re-entry to the Earth’s atmosphere, thus not contributing to the growing problem of space junk.

Using a procedure first tested last year, the CubeSats delivered by HTV-4 are first uploaded inside the ISS and later released from the Japanese Experiment Module via an airlock and robotic arm using the Small Satellite Orbital Deployer. This allows the CubeSats to be deployed directly from the ISS instead of using traditional launch vehicles, i.e., rockets.

As the deployment of micro-satellites becomes more and more cost-efficient and versatile, it’s no wonder we’re seeing an increasing prevalence of CubeSats. So think small and dream big.
