As August draws to an end, watchers of the night sky will be in for a treat. In the early morning hours of August 28, sky watchers across much of the world can look on as the Moon crosses in to the shadow of the Earth, becoming completely immersed for one-hour and 30 minutes, a period of time much longer than most typical lunar eclipses. In fact, this eclipse will be the deepest and longest in 7 years.
The event begins 54 minutes past midnight PDT (3:54 a.m. EDT) on August 28. At first, there is little change. The outskirts of Earth's shadow are as pale as the Moon itself; an onlooker might not even realize anything is happening. But as the Moon penetrates deeper in to the Earth’s shadow, a startling metamorphosis occurs. Around 2:52 a.m. PDT (5:52 a.m. EDT) the color of the Moon changes from moondust-gray to sunset-red. This is totality, and it lasts for almost 90 minutes.
With the Sun blocked, you might expect utter darkness, but instead the ground at your feet appears to be aglow. Why? Look back up at Earth. The rim of the planet seems to be on fire. Around the Earth's circumference you will witness every sunrise and sunset in the world—all at once. This incredible, colorful light beams into the heart of Earth’s shadow, transforming the Moon into a landscape of copper moondust and golden hills. The eclipse will be visible from Australia, parts of Asia and most of the Americas, but not from Africa or Europe. The view is different from each location on the planet. Here in the United States, Pacific observers are favored. For them the entire eclipse will unfold high in the post-midnight sky. However, on the East Coast, totality will be cut off early by sunrise.
Reconnaissance Orbiter Project Of the two luminaries that dominate our sky, it is the moon that is of particular interest to the Lunar Reconnaissance Orbiter (LRO) project. The LRO will travel to the moon in late fall 2008, mapping the surface to help pave the way for humans to return. It will help prepare us for extended surface exploration on the moon and for subsequent missions to Mars and other distant destinations. Lunar surface exploration will help us to practice living, working, and gathering science data before we venture into riskier territory.
Lunar Meteorite Found Although last year's inclement weather resulted in fewer Antarctic meteorite recoveries than usual, scientists have recently discovered that one of the specimens is a rare breed -- a type of lunar meteorite seen only once before.
$2.5 million Lunar Lander Challenge NASA’s Deputy Administrator Shana Dale announced during a speech at the National Space Society’s International Space Development Conference today that the first multimillion dollar NASA Centennial Challenge will be managed by the X PRIZE Foundation. X PRIZE Chairman Dr. Peter H. Diamandis presented the final rules and prize purse and officially opened the competition for team registration.
Lunar Exploration Program Returning astronauts to the moon will start with robotic missions between 2008 and 2011 to study, map and learn about the lunar surface. These early missions will help determine lunar landing sites and whether resources, such as oxygen, hydrogen and metals, are available for use in NASA's long-term lunar exploration objectives. The assignment marks a rebirth of robotic space flight work at NASA Ames, which has a history of spearheading unmanned space launches.
After nearly two weeks in space, the seven members of STS-118 returned to the astronaut crew quarters at Kennedy Space Center to unwind from their mission.
The five men and two women added a new segment to the International Space Station, delivered 5,800 pounds of supplies and equipment and teacher-turned-astronaut Barbara Morgan taught lessons from orbit during the mission. Space Shuttle Endeavour, meanwhile, is being prepared at Kennedy to move to the Orbiter Processing Facility.
NASA's two venerable Voyager spacecraft are celebrating three decades of flight as they head toward interstellar space. Their ongoing odysseys mark an unprecedented and historic accomplishment.
Voyager 2 launched on Aug. 20, 1977, and Voyager 1 launched on Sept. 5, 1977. They continue to return information from distances more than three times farther away than Pluto.
The STS-118 and Expedition 15 crews will continue cargo transfers and prepare for Saturday’s spacewalk. The 10 astronauts and cosmonauts will also hold the traditional joint crew news conference.
The Mission Management Team decided Thursday that Saturday’s spacewalk will not include repair of Space Shuttle Endeavour’s heat shield. After hours of reviewing data and imagery collected during the inspections by the STS-118 crew , the managers decided the damage did not pose a safety risk to the crew or Endeavour.
Galaxy Evolution Explorer has spotted an amazingly long comet-like tail behind a star streaking through space at supersonic speeds. The star, named Mira after the Latin word for "wonderful," has been a favorite of astronomers for about 400 years. It is a fast-moving, older star called a red giant that sheds massive amounts of surface material.
