NASA's Kepler Mission Rockets to Space in Search of Other Earths
Friday, March 6.2009
CAPE CANAVERAL, Fla. -- NASA's Kepler mission successfully launched into space from Cape Canaveral Air Force Station, Fla., aboard a United Launch Alliance Delta II at 10:49 p.m. EST,Friday. Kepler is designed to find the first Earth-size planets orbiting stars at distances where water could pool on the planet's surface. Liquid water is believed to be essential for the formation of life.
"It was a stunning launch," said Kepler Project Manager James Fanson of NASA's Jet Propulsion Laboratory in Pasadena, Calif. "Our team is thrilled to be a part of something so meaningful to the human race -- Kepler will help us understand if our Earth is unique or if others like it are out there."
Engineers acquired a signal from Kepler at 12:11 a.m. Saturday, after it separated from its spent third-stage rocket and entered its final sun-centered orbit, trailing 950 miles behind Earth. The spacecraft is generating its own power from its solar panels.
"Kepler now has the perfect place to watch more than 100,000 stars for signs of planets," said William Borucki, the mission's science principal investigator at NASA's Ames Research Center at Moffett Field, Calif. Borucki has worked on the mission for 17 years. "Everyone is very excited as our dream becomes a reality. We are on the verge of learning if other Earths are ubiquitous in the galaxy."
Engineers have begun to check Kepler to ensure it is working properly, a process called "commissioning" that will take about 60 days. In about a month or less, NASA will send up commands for Kepler to eject its dust cover and make its first measurements. After another month of calibrating Kepler's single instrument, a wide-field charge-couple device camera, the telescope will begin to search for planets.
The first planets to roll out on the Kepler "assembly line" are expected to be the portly "hot Jupiters" -- gas giants that circle close and fast around their stars. NASA's Hubble and Spitzer space telescopes will be able to follow up with these planets and learn more about their atmospheres. Neptune-size planets will most likely be found next, followed by rocky ones as small as Earth. The true Earth analogs -- Earth-sized planets orbiting stars like our sun at distances where surface water, and possibly life, could exist -- would take at least three years to discover and confirm. Ground-based telescopes also will contribute to the mission by verifying some of the finds.
In the end, Kepler will give us our first look at the frequency of Earth-size planets in our Milky Way galaxy, as well as the frequency of Earth-size planets that could theoretically be habitable.
"Even if we find no planets like Earth, that by itself would be profound. It would indicate that we are probably alone in the galaxy," said Borucki.
As the mission progresses, Kepler will drift farther and farther behind Earth in its orbit around the sun. NASA's Spitzer Space Telescope, which was launched into the same orbit more than five years ago, is now more than 62 million miles behind Earth.
Kepler is a NASA Discovery mission. Ames is the home organization of the science principal investigator and is responsible for the ground system development, mission operations and science data analysis. JPL manages the Kepler mission development. Ball Aerospace & Technologies Corp. of Boulder, Colo., is responsible for developing the Kepler flight system and supporting mission operations. NASA's Launch Services Program at NASA's Kennedy Space Center, Fla., managed the launch service including payload integration and certifying the Delta II launch vehicle for NASA's use.

March is Women's History Month
Theme:
"Get to Know the Women Who’ve Changed Our World."
History of National Women's History Month
The Beginning
As recently as the 1970's, women's history was virtually an unknown topic in the K-12 curriculum or in general public consciousness. To address this situation, the Education Task Force of the Sonoma County (California) Commission on the Status of Women initiated a "Women's History Week" celebration for 1978. We chose the week of March 8 to make International Women's Day the focal point of the observance. The activities that were held met with enthusiastic response, and within a few years dozens of schools planned special programs for Women's History Week, over one-hundred community women participated in the Community Resource Women Project, an annual "Real Woman" Essay Contest drew hundreds of entries, and we were staging a marvelous annual parade and program in downtown Santa Rosa, California.
The Entire Month of March
In 1987, the National Women's History Project petitioned Congress to expand the national celebration to the entire month of March. Since then, the National Women's History Month Resolution has been approved with bipartisan support in both the House and Senate. Each year, programs and activities in schools, workplaces, and communities have become more extensive as information and program ideas have been developed and shared.
Growing Interest in Women's History
The popularity of women's history celebrations has sparked a new interest in uncovering women's forgotten heritage. A President's Commission on the Celebration of Women in History in America recently sponsored hearings in many sections of the country. It took reports about effective activities and institutions that are promoting women's history awareness and heard recommendations for programs still needed. The Women's Progress Commission will soon begin hearings to ascertain appropriate methods for identifying and then preserving sites of importance to American women's history. In many areas, state historical societies, women's organizations, and groups such as the Girl Scout of the USA have worked together to develop joint programs. Under the guidance of the National Women's History Project, educators, workplace program planners, parents and community organizations in thousands of American communities have turned National Women's History Month into a major focal celebration, and a springboard for celebrating women's history all year 'round.
