Most people know that satellites in orbit do useful things such as collect images of the Earth's surface. At the National Air and Space Museum I use satellite images in my job to understand changes in the Earth's land surface.
On the morning of March 2, I got an excited text message from fellow astronomy educator Shelley Witte, telling me that the International Space Station (ISS) and Space Shuttle Discovery would be coming very close to transiting the Sun from our position at the National Air and Space Museum’s Public Observatory at exactly 3:08 pm.
On Saturday, March 19, I was thrilled to participate in the first ever Sun-Earth Day Tweetup organized by the NASA Goddard Spaceflight Center. It was also the first time the Smithsonian officially participated in a Tweetup. The event was a great opportunity to give twitter fans (aka “tweeps”) some face-to-face interaction with our research scientists, curators and educators, and provide some fun hands-on learning that illustrated the Sun-Earth connection.
The 2011 Major League Baseball season starts today at 1:05pm, when the National Air and Space Museum’s hometown Washington Nationals host the Atlanta Braves at Nationals Park. This afternoon the red and white uniforms of the Nationals will stand out against the bright green of the field. In the late 1950s, players took to the field of the U.S. Naval Air Material Center in Philadelphia wearing a different uniform—B.F. Goodrich Mark IV spacesuits.
The first decade of the twenty-first century has offered both serious challenges and enormous potential for the development of new human launch vehicles that could finally achieve the long-held dream of reliable, affordable access to space. But at the end of the decade, the policy questions posed by the 2003 loss of Columbia about the future U.S. human spaceflight still loom large.
Today at 8:45 pm EDT (March 18, 2011, 12:45 am UTC), MESSENGER will become the first spacecraft ever to enter Mercury's orbit. With MESSENGER on the last leg of its journey, I’m reminded how long it has taken to get there. I watched the spacecraft launch in the early morning hours of August 3, 2004, almost six and a half years ago. Now after one flyby of Earth, two flybys of Venus, and three flybys of Mercury, the spacecraft will catch up with Mercury again, but this time it will be captured by the planet. You might think as one of our closest neighbors in the Solar System it would take a lot less time to get into Mercury orbit – but because Mercury is the closest planet to the Sun, at a distance where the influence of the Sun’s gravity is much greater, it is a challenge to reach and orbit.
As we begin to take occupancy of our new home in the Steven F. Udvar-Hazy Center’s new wing, and begin the process of outfitting the Mary Baker Engen Restoration Hangar, we are faced with the daunting task of moving all of our equipment into the new spaces and setting up an environment which will be favorable to the preservation and restoration of our priceless artifacts for decades to come. This is likely to be a lengthy process but we have begun to deliver selected artifacts so that when the viewing area becomes accessible, visitors will be able to see examples of our gems in the rough. Each of these aircraft has been in storage at the Paul E. Garber Facility in Suitland, Maryland for years, where the Museum's restoration work had taken place for decades. These aircraft are seldom seen by the public, and are all in need of preservation or restoration treatments.
For a number of years now, the United States has set aside February and March to celebrate Black History Month and National Women’s History Month, respectively. While these commemorations are praiseworthy, they should not disguise the fact that they have been rather contentious culturally. Some would argue that it is insulting to African Americans to celebrate their history for only one month every year. In the case of women, National Women’s History Month has become a call to arms in an ongoing struggle for women’s rights, to ensure educational and economic opportunities for all women, and for ending violence against them.
On December 7, 1941, a US Navy squadron consisting of ten Sikorsky JRS-1 amphibious seaplanes was on station in the Hawaiian Islands. Shortly after the Japanese attack that Sunday morning, the planes were launched in an effort to locate enemy submarines and ships near Oahu.
