The International Space Station is seen passing across the face of the Moon in this beautiful image, taken on April 5 by Fernando Echeverria about 15 minutes before the launch of Discovery. In photography timing really is everything! The Station’s altitude ranges from 173 to 286 miles above the Earth, traveling at a speed of…
Rings of Light
Viewed from its night side sunlight illuminates Saturn’s atmosphere and rings, creating brilliant arcs of light in this image from Cassini, taken on February 13. Saturn’s shadow darkens the near side of the rings while their distant Sun-facing portion casts its own shadow into the atmosphere, in the bottom half of the image. The Cassini…
This Week in Space
The Discovery crew outlines the upcoming STS-131 mission (scheduled to launch at 6:21am EST tomorrow), new ISS team members blast off to work from Kazakhstan, Toyota teams up with NASA to investigate some out-of-this-world causes to their products’ malfunctions, Spirit settles down for a long [Martian] winter’s nap, Saturn’s moon Mimas shows off its retro…
Flying Pan
Making a complete orbit in just under 14 hours, the 17-mile-wide shepherd moon Pan cruises around Saturn within the Encke gap in the A ring. In the image above, taken by Cassini on January 8, we can see Pan casting a sliver of a shadow onto the outer edge of the gap as it causes…
Little Sister
111-mile-wide Janus passes in front of the face of her much larger sister Titan in this image from Cassini, taken on March 27. At 3,200 miles wide, Titan is one of the largest moons in the solar system, even larger than the planet Mercury. A thick atmosphere keeps its frigid and gloomy surface permanently hidden…
Now That’s a Moon!
Just released today, this portrait of Saturn’s moon Mimas showcases its striking similarity to the Death Star (pre-proton torpedoes of course). The Cassini imaging team has been hard at work processing the images from last month’s flyby and the results sure don’t disappoint! On February 13 Cassini passed Mimas at a distance of 5,900 miles…
A Grand View
Cutting over a mile into the surrounding landscape, the Grand Canyon in Arizona is one of the most amazing places I have ever visited…and it’s no less beautiful from 200 nautical miles up! This photo was taken today by Japanese astronaut Soichi Noguchi aboard the International Space Station and immediately sent to his TwitPic page…
Rhea and the Rings
This is one of those sublime photos from Cassini that just make me smile. Taken on March 24, this raw image shows Rhea, Saturn’s second-largest moon, suspended in orbit in front of the twilight side of Saturn, its rings reduced to a thin ribbon of bands at this viewing angle. The width of the rings…
Darken the Lights
This Saturday, from 8:30 to 9:30pm your local time, join millions of people around the world in celebration of the 4th annual Earth Hour by turning off the lights in your home or office. It’s a message of support for our planet! It’s about individual empowerment and generating an interest and a global voice on…
Lady’s Choice
Scientists prove it: a girl knows how to make up her mind. The image above shows the first target object – that football-sized layered rock – autonomously chosen by the Mars rover Opportunity on March 4. Opportunity selected the rock after taking a series of wide-angle panoramic images of the area and using her new…
You say potato, I say Prometheus.
Here’s a nicely processed-and-polished photo of Saturn’s moon Prometheus, fresh from the Cassini imaging center at the Space Science Institute in Boulder, CO. Taken during the spacecraft’s flyby of the F-ring’s shepherd moon earlier this year, this image shows Prometheus’ potato-like shape and heavily cratered surface on its trailing side, dimly illuminated by reflected light…
This Week in Space
The space shuttle Discovery prepares for launch and new discoveries from NASA’s Wide-Field Infrared Survey Explorer…kamikaze comets, another exoplanet spotted, a closer look at the moons Rhea, Pallene and Phobos, lost spacecraft, an interview with retired astronaut Bernard Harris and lots more in this edition of This Week in Space with Miles O’Brien. Enjoy! Provided…
