Could An 18,000lb Lost Satellite Cause A 'Gravity'-Style Disaster?

Details Published on Saturday, 22 February 2014 10:16

A satellite which the European Space Agency lost contact with in 2012 could create a similar cloud of space debris which hit the International Space Station in the film 'Gravity'A bus-sized satellite that is lost in space could break up and spark a devastating field of debris similar to that which hit Sandra Bullock and George Clooney in the film Gravity.

The threat comes from the nine-metre wide Envisat satellite which lost contact with Earth in 2012 and now orbits under at an altitude of 491 miles (790km).

Scientists believe there is a chance of collision with other satellites and debris during the 150 years it is expected to remain in space. But bringing the satellite back to Earth may prove too costly.

Each year, scientists believe two objects pass the 18,000lb satellite by within about 200m and other spacecraft have had to move out of Envisats path.

It is possible that a collision with Envisat could lead to a chain reaction effect, known as the Kessler Syndrome, which refers to when a cloud of fast-moving debris causes other collisions.

This is the type of a cloud that hit Bullock and Clooney during a spacewalk outside the International Space Station in the film Gravity.

The fact that Envisat is in a near-polar orbit doesnt help, since its path intersects most satellites orbits nearly at right angles, said Professor George Fraser, Director of the Universitys Space Research Centre.

Imagine driving down the motorway and every so often a large truck cuts right across all four lanes right in front of you.

Physics students at Leicester University claim it could make it difficult for future space missions to pass through the region of Envisats altitude, if the region becomes congested with space debris.

Branson says space flight ready this year

AP Sir Richard Branson says the inaugural Virgin Galactic flight into space will take place this year.

UK businessman Sir Richard Branson has reiterated his claim that the first Virgin Galactic flight into space will take place later this year.

The launch date for the much-delayed project has been put back repeatedly from the original 2007 forecast, but the Virgin entrepreneur has confirmed he will fly with his children on the inaugural flight later in 2014.

Celebrities including Hollywood actors Tom Hanks and Angelina Jolie have apparently reserved spaces to become space tourists, with tickets costing six figures and including brief periods of weightlessness during the two-hour trip to 100km above the Earth.

Branson says in an interview with the Guardian that the first unmanned test flight will take place soon.

The inaugural flight - due later this year - will be televised live by American broadcaster NBC.

"Without a doubt, Sir Richard and his children taking the first commercial flight into space will go down in history as one of the most memorable events on television," NBC said in a statement to the newspaper.

Last month Virgin Galactic's SpaceShipTwo made its third rocket-powered supersonic flight in the Mojave Desert, soaring to a record 21,600 metres.

The company says the reusable space vehicle was carried by aeroplane to 14,000 metres the day before, and then released.

The craft used its rocket motor the rest of the way to reach its highest altitude to date. SpaceShipTwo and its two-member crew then glided to a safe landing in the desert north of Los Angeles.

Businessman Richard Branson has reiterated his claim that the first Virgin Galactic flight into space will take place later this year.

The launch date for the much-delayed project has been put back repeatedly from the original 2007 forecast, but the Virgin entrepreneur has confirmed he will fly with his children on the inaugural flight later in 2014.

Celebrities including Hollywood actors Tom Hanks and Angelina Jolie have apparently reserved spaces to become space tourists, with tickets costing six figures and including brief periods of weightlessness during the two-hour trip to 62 miles above the Earth.

In an interview with the Guardians Weekend magazine, Sir Richard said: When I started Virgin Atlantic, I knew nothing about running airlines. I just felt somebody should be able to do it better than British Airways.

Then we got a lot of creative people who werent from the airline world to go and shake up the business. Starting a spaceship company is not that dissimilar.

According to the Guardian, Sir Richard said the first unmanned test flight will take place soon, and the newspaper said the inaugural flight due later this year will be televised live by American broadcaster NBC.

In a statement to the newspaper, it said: Without a doubt, Sir Richard and his children taking the first commercial flight into space will go down in history as one of the most memorable events on television.

Last month Virgin Galactics SpaceShipTwo made its third rocket-powered supersonic flight in the Mojave Desert, soaring to a record 71,000 feet.

The company says the reusable space vehicle was carried by aeroplane to 46,000 feet the day before, and then released.

Green Kiwi tux heads to Oscars red carpet

The wife of an Oscar winner and the daughter of Cambodian refugees met on a Wairarapa farm yesterday over an unlikely object - a tuxedo made partly of recycled bottles, to be worn by a vampire.

When Suzy Amis-Cameron, wife of blockbuster director James Cameron, was told in a Los Angeles meeting that the winner of her eco-fashion competition was from New Zealand she was amazed: "The connection couldn't be more meaningful than having the winner be from our new home."

The new menswear section of Amis-Cameron's ecologically conscious fashion design competition, Red Carpet Green Dress, was won by Hallenstein Brothers' designer Jomnarn Dul, whose parents fled to New Zealand from Cambodia via a Thai refugee camp.

There, her mother sewed clothes for people who had fled with nothing; yesterday, the Aucklander was hosted by Amis-Cameron at her Wairarapa farm to celebrate the success, which will see Dul's design worn on the red carpet at next Sunday's Oscars by actor Kellan Lutz, who played vampire Emmett Cullen in the Twilight movies.

Former model and actress Amis-Cameron, 52, founded the design competition five years ago, inspired by her husband's box office record-breaking film, Avatar, which has a strong conservation message.

"We were in one of our brain-mash pow-wows and someone said, why don't we do a dress-design competition?"

The motivation was fundraising for her conservation-oriented, not-for-profit MUSE School in California, founded with sister Rebecca Amis nine years ago, which provides scholarships to half its students.

Each year since, the winning gown, made of sustainably produced fabrics, has been worn by an actress on the red carpet at the Academy Awards.

Amis-Cameron, a mother of three children with Cameron, as well as one from a previous marriage and one from one of Cameron's previous marriage, tries to dress her family in fabrics which were neither toxic for the planet, nor for their bodies, and made without "destroying lives" in sweat-shops.

"It's a much, much bigger issue for me, it's not just a pretty dress to wear on the red carpet . . . Everybody wears clothes."

Red Sox will lean on Lester, deep rotation

FORT MYERS, Fla. (AP) -- The "no vacancy" sign is up for the Red Sox rotation.

With five veteran starters, the World Series champions have no openings. But if they did, there would be several outstanding young candidates competing for them -- and others not too far away.

Coming off a brilliant postseason, Jon Lester leads the starting staff after pitching a career-high 213 1-3 innings. Clay Buchholz, John Lackey, Jake Peavy and Felix Doubront complete the group that should have little trouble weathering Ryan Dempster's decision not to play in 2014 for physical and personal reasons.

Brandon Workman heads the young group after a year in which he wasn't even in the major league camp yet went 6-3 with the Red Sox. Manager John Farrell showed faith by having him pitch the eighth inning -- he retired St. Louis in order -- of Boston's clinching Game 6 of the World Series.

The more pitching, the better.

"I don't think any of us have any false confidence or an embarrassment of riches because we've seen that pitching is a game of attrition," Farrell said Friday. "We went through 20-something relievers last year so we were fortunate, with the exception of maybe Clay's situation, we were relatively healthy in the rotation. But that can change in a moment's notice."

Like when Dempster surprised management about two weeks ago with his decision not to play the final year of his contract.

So the Red Sox added left-hander Chris Capuano to work in the bullpen and as insurance for the rotation.

Keep up with your favorite teams and athletes with daily updates.

FORT MYERS, Fla. (CBS) -Another day of workouts in the books on this Saturday down here at Red Sox Spring Training in Fort Myers.

Here are some notes and observations:

CHRIS CAPUANO

Chris Capuano was on the field with his new teammates after signing a one year contract and passing his physical.

Capuano was born and raised in West Springfield and graduated from Cathedral High School. He will wear number 55. He says he grew up a Sox fan and was devastated by the 1986 World Series at the age of 8.

Amazingly, the only park that the 31-year-old hasnt pitched in as a big leaguer is Fenway. He said he did pitch there once when he played for Massachusetts in a Mass. vs Connecticut All-Star game when he was in high school. Hes expected to be extended as a starter in the spring, but will be used as a third lefty out of the bullpen, at least initially once the season begins.
