In what may be the best single representation of the visual feast of images we have enjoyed from Expedition 28 flight engineer Ron Garan during his 5 1/2 month stay aboard the ISS, this amazing image shows him inside the Station’s cupola as he took his last images of Earth before departing. I must say,…

As The World Turns
Today is the autumnal equinox, when the Earth receives sunlight at its most direct angle relative to its equator and poles. As Earth orbits around the Sun over the course of a year, its axial tilt causes the angle of solar illumination to change – a predictable and regular change, but a change nonetheless. This…
Juno Looks Back Home
It’s not the famous “pale blue dot” image, but it sure is close: on August 26 the Juno spacecraft turned its JunoCam to take this image of the Earth and the Moon from a distance of about 6 million miles. From that distance, our world is effectively reduced to a bright fuzzy dot, with a smaller,…
Say Hello To Our Little Friend
On July 27, 2011, scientists announced the discovery of a small asteroid that shares its orbit with Earth: 2010 TK7, a 1,000-foot-wide asteroid, precedes our planet within the same path we take around the Sun. It’s currently located about 50 million miles away in a position known as a Lagrange point (L4, to be exact) where…
One Year of Moon
Can’t see the video below? Click here. This awesome animation by the visualization folks at NASA’s Goddard Space Flight Center shows the phases and position of the Moon throughout 2011 – a full year of the Moon compressed into 2.5 minutes! What’s really interesting is how you can see the wobble of the Moon in…
An Astronaut’s View of Earth
Can’t see the video below? Click here. This really is a must-see… it’s a video by NASA TV showing our planet as it is experienced by the privileged few who have flown in space and spent time aboard the International Space Station. Looking down on the landscapes of our world from orbit, passing 225 miles…
First Orbit: Celebrating 50 Years in Space
On April 12, 1961 – a mere five decades ago – Russian cosmonaut Yuri Gagarin was launched aboard his Vostok-1 spacecraft, becoming the first human in space. Alone, he was the first person ever to look down upon our planet from orbit. He was only 28 years old. Today the world celebrates the 50th anniversary…
Afternoon Delight
I spotted this on the SDO site late this afternoon…it shows an eruption of plasma from the Sun’s photosphere that stretches out many tens of thousands of miles…the Earth could easily fit many times over beneath the looping structure! This image is from about 5pm EDT (21:59 UT), and shows the eastern limb of the Sun,…
There Goes The Sun
The Sun was briefly slashed in half diagonally when Earth’s atmosphere hid it from the view of NASA’s SDO spacecraft on April 1, 2011. (No foolin’!) SDO is currently in an orbit that puts the Earth between it and the Sun momentarily each day. When this happens, SDO’s view is blocked completely for several minutes…
One Earth. One planet. One hour.
Earth Hour. On Saturday, March 26 at 8:30pm – 9:30pm your local time, join millions of people who will show their support for our world’s environmental future by turning off the lights in your home or business for one hour. That’s it. Lights out. It’s a small reduction in power usage, but a big message…
Dock of the Day
At 2:14pm EST today the space shuttle Discovery successfully docked with the International Space Station, 220 miles above Australia. This will be the last time Discovery will visit the space station, indeed the last time it will fly at all in its long and illustrious career. The image above was pulled from live video feed…
From the LITD Archives: Voyager’s Valentine
On February 14, 1990, after nearly 13 years of traveling the outer solar system the Voyager 1 spacecraft passed the orbit of Pluto and turned its camera around to take a series of photos of the planets. The image above shows those photos, isolated from the original series and labeled left to right, top to…
