In a timed exposure, spectators watch from Cocoa Beach as the Kepler satellite launches from Cape Canaveral Air Force Station, Fla. March 6.

NASA’s Kepler spacecraft blasted off from Kennedy Space Center in Florida on Friday on a three-year mission to find Earth’s twin, a Goldilocks planet where it’s neither too hot nor too cold, but just right for life to take hold.

The Delta II rocket, carrying the widest-field telescope ever put in space, lifted off the launch pad at Cape Canaveral at 10:49 p.m. Eastern time.

The $590-million Kepler mission is jointly managed by JPL and NASA’s Ames Research Center in the Bay Area. The spacecraft carries a 15-foot-long telescope with a 55-inch mirror that can scrutinize a wide star field for the telltale dimming of starlight that occurs when a planet crosses in front of it, known as a transit.

Over the last decade, scientists have employed the same technique with ground-based telescopes to discover 340 planets circling other stars. But because the optics of ground-based instruments are compromised by atmospheric interference, most of the planets found so far are Jupiter-like gas giants that orbit so close to their parent stars that any life forms would be incinerated.

The orbiting Hubble Space Telescope, whose optics are not hampered by Earth’s atmosphere, was designed to see deeply but very narrowly.

Kepler’s field of view is 33,000 times wider than Hubble’s, or about the size of a human hand held up to the sky. The Cygnus-Lyra region near the plane of the Milky Way encompasses about 4.5 million stars. But most of those are too big or hot to allow a habitable zone close enough to the star for Kepler to see a transit.

The science team has selected about 150,000 sun-like stars for Kepler to analyze. Over time, Fanson said, the number will be winnowed down to about 100,000 in three classes: G-type stars, which are similar in size and age to the sun; K- and M-type stars, which are slightly smaller and cooler; and A- and F-class stars, which are somewhat bigger.

Earth is in the center of the habitable zone around the sun, but with stars of other classes, that zone would be closer to the star or farther out.

Kepler’s telescope is outfitted with a sophisticated camera that will stare unblinkingly at the star field. The whole area will be imaged every six seconds, then stored in 30-minute chunks.

Once a month, Kepler will do a pirouette in space to download its stored data, Fanson said.

Miep Gies kept Anne Frank’s diary safe before its publication The last surviving member of the small group who helped hide the Dutch Jewish girl Anne Frank and her family from the Nazis has turned 100 years old. Miep Gies will celebrate her birthday on Sunday quietly with relatives and friends, she said this week. She said she was not deserving of the attention, and that others had done far more to protect the Netherlands’ Jews. She paid tribute to “unnamed heroes”, picking out her husband Jan for his courageous defiance of the Nazis. “He was a resistance man who said nothing but did a lot. During the war he refused to say anything about his work, only that he might not come back one night. People like him existed in thousands but were never heard,” Miep Gies said in an email to the Associated Press this week. Accolades Mrs Gies was an employee of Anne Frank’s father, Otto, who kept them and six others supplied during their two years in hiding in an attic in Amsterdam from 1942 to 1944. But the family were found by the authorities, and deported. Gies, bottom left, and Otto Frank, next to her, were reunited after the war Anne Frank died of typhus in the German concentration camp of Bergen-Belsen later. It was Mrs Gies who collected up Anne Frank’s papers, and locked them away, hoping that one day she would be able to give them back to the girl. In the event, she returned them to Otto Frank, and helped him compile them into a diary that was published in 1947. It went on to sell tens of millions of copies in dozens of languages. She became a kind of ambassador for the diary, travelling to talk about Anne Frank and her experiences, campaigning against Holocaust-denial and refuting allegations that the diary was a forgery. For her efforts to protect the Franks and to preserve their memory, Mrs Gies won many accolades. “This is very unfair,” she told the Associated Press. “So many others have done the same or even far more dangerous work.”
