A Lockheed-Martin built Atlas V launch vehicle, successfully launched from Cape Canaveral, Florida at 21:42 UTC (4:42 p.m. EST). It placed the Inmarsat 4 F-1 communications satellite into orbit. This was Lockheed-Martin’s second try to launch the satellite. Yesterday’s attempt ended in a scrub when the flight control computer passed a red-line with less than three minutes remaining in the countdown.

This was the fifth launch of the Atlas V vehicle, and the first launch where the rocket used three of the first stage, Aerojet built, solid rocket motors. It also had the narrower 4 meter payload fairing.

For the first part of the flight, the rocket was powered by a common booster core with two RD-180 rocket engines plus three solid rocket motors. When their fuel was expended the solid rocket motors burned out and were jettisoned.

The common booster core then continued pushing the payload and upper stage, with its two RD-180 engines producing 806,000lbf of thrust. The common booster core expended its fuel around four and a half minutes into the flight. At this point the first stage common booster core separated from the upper stage and payload.

After the stage separation, the Centaur upper stage started its engine and burned for nearly ten minutes. During this burn, the payload fairing separated from the spacecraft, leaving the satellite exposed on the nose of the rocket in the vacuum of space. When the ten minute burn was up, the Centaur coasted with the satellite for another ten minutes waiting to get to the optimal point for the final burn. At around 24 minutes into the flight, the final burn of the Centaur stage occurred, placing the spacecraft in a super-synchronous transfer orbit. After this burn was complete, the Centaur separated, leaving the spacecraft on its own.

Now the spacecraft must attempt to open its solar arrays and place itself in the final geostationary orbit. Because of this special type of orbit, where the spacecraft goes around once every 24 hours, the satellite will appear to sit in one place over the equator. From this location, Inmarsat will use it to provide BGAN (Broadband Global Area Network) which is a 3G compatible, 432kbit/s data service, to much of the world.

The Atlas vehicle was rolled out of its vertical integration facility 1800 feet from the launch pad early yesterday morning (before the first launch attempt). The reason for this launch day move is because of the clean pad concept.

Past American rockets (with the exception of the Saturns and Space Shuttles) have always been assembled on the launch pad. In the case of a delay in launching, this would cause delays in all the rockets that needed to be launched after the one that experienced the delay. With the new clean pad concept, rockets can be assembled and checked out before being moved to the pad, saving delays in the schedule.

The launch tower and rocket move out to the pad along a set of railroad tracks, making the 1800 foot journey in approximately half an hour, topping out around two miles per hour.

Because of the clean pad concept, none of the launch control electronics or spacecraft environmental systems are on the pad. Instead, they are run along the railroad tracks with the rocket as it moves to the pad on launch day. When they get there, they slide into concrete enclosures so that they are not destroyed during the rocket launch.

Australia –The whole of the east coast of Australia has been lashed by severe storms in the last 24 hours, with at least one reported death. Wind gusts in some areas reached 110 kilometers per hour, and flash flooding and power cuts were reported from Far North Queensland to Tasmania in the South.

State Emergency Services (SES) crews are stretched to the limit, working into the night to cope with the effects of the freak weather.

Muslim groups from across the world are criticising the organisers of the 2012 Olympics in London after it was revealed that the games will take place over Ramadan. The most holy month in the Muslim calendar, which will take place from the 21 July to 20 August in 2012, involves fasting during daylight hours and will affect an estimated 3,000 athletes.

Joanna Manning Cooper, spokesman for the games said: “We did know about it when we submitted our bid and we have always believed that we could find ways to accommodate it.”Nevertheless, this will come as a huge embarrassment for the organisers who have tried to ensure the event involve all of Britain’s ethnic communities.A quarter of the athletes who took part in the 2004 Athens Olympics were from predominantly Muslim countries and the fast will put any athletes involved at a clear disadvantage.

The chairman of the Islamic Human Rights Commission, Massoud Shadjared said: “This is going to disadvantage the athletes and alienate the Asian communities by saying they don’t matter. It’s not only going to affect the participants, it’s going to affect all the people who want to watch the games.”

The president of the National Olympic Committee of Turkey, Togay Bayalti, said: “This will be difficult for Muslim athletes. They don’t have to observe Ramadan if they are doing sport and travelling but they will have to decide whether it is important to them. “It would be nice for the friendship of the Games if they had chosen a different date.”

The games will run from the 27 July to 12 August to coincide with the British Summer holidays. The summer holidays are a six week period running from mid July to early September. During this time, public transportation is generally less crowded and it will be easier to find the 70,000 volunteers needed to keep the games running. The International Olympics Committee has specified that the games must take place between July 15 to August 31. Giselle Davies, IOC spokesperson said, “We give a window to the five bid cities. The host city selects the dates within that window.”

The organisers are working with the Muslim Council of Great Britain to find ways around the problem.

The London Planetarium, famous for its distinctive green dome and for being next to Madame Tussauds, will close this week to make way for a new celebrity-themed show opening in July. The Planetarium used to be an attraction in its own right, but in recent years has become simply a feature tacked onto the end of the waxworks tour, the original 45 minute show cut down to just over 10 minutes. The planetarium will be renamed ‘The Auditorium’ and will feature a show that “gets to the heart of celebrity”, being produced in collaboration with animation house Aardman Productions.

Famous astronomer Sir Patrick Moore has called the decision “most regrettable”, and many have commented that the change from space to celebrity is an unfortunate sign of our times.

To say ‘farewell’ to the planetarium, Tussauds have allowed free entry in its penultimate week, from 24th – 30th April. Visitors could enter through the group admissions entrance to see the show, running every twenty minutes. Unlike the queues for Madame Tussauds, which typically run right up the street, few people waited to see the planetarium show, even on the Saturday. The show, titled Journey to Infinity, was projected onto the inside of the dome using Digistar 3 digital projectors. It told the story of space, starting from Earth and zooming out to reveal the other planets in the Solar System, the Milky Way, the other galaxies and the rest of the universe. It ended with an optimistic message suggesting that humans would continue to explore space, going further than ever before.

The London Planetarium opened in 1958 on the site of an old cinema that was destroyed in the second world war. Evening laser performances called ‘Laserium’ were held between 1977 and 1990. A £4.5 million redevelopment saw it relaunch in 1995 with a new ‘Digistar II‘ monochromatic 3D projection system. This was upgraded to the full-colour ‘Digistar 3‘ system in 2004 which is currently in use.

The planetarium at the also famous Royal Observatory in Greenwich has also been closed since September 2004, however this is due to re-open in 2007 having received a £15 million redevelopment programme. It will be three times the size of the old planetarium, and has received backing from Astronomer Royal Sir Martin Rees, and the Astronomer Royal for Scotland, Professor John Brown.

The Kennedy Center announced that its 30th presentation of the Kennedy Center Honors would go to pianist Leon Fleisher, comedian Steve Martin, singer Diana Ross, director Martin Scorsese and musician Brian Wilson. The Center was opened to the public in 1971 and was envisioned as part of the National Cultural Center Act, which mandated that the independent, privately-funded institution would present a wide variety of both classical and contemporary performances, commission the creation of new artistic works, and undertake a variety of educational missions to increase awareness of the arts.

In a statement, Kennedy Center Chairman Stephen A. Schwarzman said that “with their extraordinary talent, creativity and perseverance, the five 2007 honorees have transformed the way we, as Americans, see, hear and feel the performing arts.”

Fleisher, 79, a member of the Peabody Institute‘s music faculty, is a pianist who lost use of his right hand in 1965 due to a neurological condition. He became an accomplished musician and conductor through the use of his left hand. At 67, he regained the use of his right hand. With the advent of Botox therapy, he was once more able to undertake two-hand performances in 2004, his first in four decades. “I’m very gratified by the fact that it’s an apolitical honor,” Fleisher said. “It is given by colleagues and professional people who are aware of what [an artist] has done, so it really is apolitical — and that much more of an honor.”

Martin, 62, a comedian who has written books and essays in addition to his acting and stand-up comedy career, rose to fame during his work on the American television program Saturday Night Live in the 1970’s. Schwarzman praised his work as that of a “renaissance comic whose talents wipe out the boundaries between artistic disciplines.” Martin responded to the honor saying, “I am grateful to the Kennedy Center for finally alleviating in me years of covetousness and trophy envy.”

Ross, 63, was a product of Detroit‘s Brewster-Douglass Projects when as a teeager she and friends Mary Wilson and Florence Ballardis formed The Supremes, a ground-breaking Motown act. She portrayed singer Billie Holiday in the 1972 film Lady Sings the Blues, which earned her an Oscar nomination and a Golden Globe award. “Diana Ross’ singular, instantly recognizable voice has spread romance and joy throughout the world,” said Schwarzman. Ross said she was “taken aback. It is a huge, huge honor and I am excited to be in this class of people.”

Scorsese, 64, is one of the most accomplished directors the United States ever produced, whose work includes Mean Streets, Taxi Driver, GoodFellas, Cape Fear, The Last Temptation of Christ and The Departed, for which he won a 2006 Academy Award for Best Director after being nominated eight times. Scorsese said, “I’m very honored to be receiving this recognition from the Kennedy Center and proud to be joining the company of the very distinguished individuals who have received this honor in years past.”

Wilson, 65, along with his brothers Dennis and Carl, formed the Beach Boys in 1961. They had a series of hits that included “Surfin’ U.S.A.” and “Wouldn’t It Be Nice.” Their 1966 album Pet Sounds is considered one of the most influential recordings in American music. “This is something so unexpected and I feel extremely fortunate to be in the company of such great artists,” said Wilson, who is currently on tour.

The Kennedy Center’s board of trustees is responsible for selecting honorees for “lifetime contributions to American culture through the performing arts.” Previous honorees, including Elton John and Steven Spielberg, also submitted recommendations. A wide variety of people were under consideration, including Emanuel Ax, Evgeny Kissin, Renee Fleming, Laurence Fishburne, Francis Ford Coppola, Melissa Etheridge and Kenny Chesney.

President Bush and first lady Laura Bush will attend the center’s presentation at its opera house on December 2, 2007, which will broadcast on December 26 on CBS.
