The Six Million-Mile View of Earth and Moon

Looking homeward in its long journey to +Jupiter, NASA’s Juno spacecraft offered up this rare view of our home planet with its moon. The spacecraft was some six million miles (nearly 10 million kilometers) from Earth when it took this photo on August 26, 2011. From this distance, oceans, land, clouds, and ice blend into a blur of light, a mere dot against the vastness of space. Even fainter and smaller, the +Moon provides an additional sense of scale. Separated by just over an inch (about 3 centimeters) in this photo, the Earth and Moon are about 250,000 miles or 402,000 kilometers apart.

Juno traveled this distance, from the Earth to the Moon, in less than a day. The spacecraft launched on August 5, and will reach Jupiter, another 1,740 million miles (2,800 million kilometers) away, in about five years. The mission team took the photo as part of the first detailed check of the spacecraft’s instruments and subsystems.

“This is a remarkable sight people get to see all too rarely,” said Scott Bolton, Juno principal investigator from the Southwest Research Institute in San Antonio, in a NASA release. “This view of our planet shows how Earth looks from the outside, illustrating a special perspective of our role and place in the universe. We see a humbling yet beautiful view of ourselves.”

The photo and other checks show that Juno is healthy and on course for Jupiter. Once it reaches Jupiter, Juno will orbit the planet’s pole taking measurements that will provide insight into Jupiter’s origin, structure, atmosphere and magnetosphere. Juno will also help determine if Jupiter, a gas giant, has a solid core.

"Photography is about finding out what can happen in the frame. When you put four edges around some facts, you change those facts."

HEART AND CIRCULATORY SYSTEM
How they work explained in 90 seconds
... oxygen-poor blood = blue blood ...
... oxygen-rich blood = red blood ...
... heart's right side pumps the blue to the lungs ...
... lungs refresh the blue to red with new oxygen ...
... heart's left side pumps the red to body tissues ...
