NASA has delayed the launch of its new James Webb Space Telescope following an “incident” that happened affecting its connection to the rocket.
The $10bn (£7.5bn) telescope is an orbiting infrared observatory that will will provide next-generation discoveries based on the work of the Hubble Space Telescope.
But its launch from the Guiana Space Centre in French Guiana – the base of operations for the European Space Agency – has now been pushed back until 22 December at the earliest.
NASA said: “The incident occurred during operations at the satellite preparation facility in Kourou, French Guiana, performed under Arianespace overall responsibility.
“Technicians were preparing to attach Webb to the launch vehicle adapter, which is used to integrate the observatory with the upper stage of the Ariane 5 rocket.

“A sudden, unplanned release of a clamp band – which secures Webb to the launch vehicle adapter – caused a vibration throughout the observatory,” the space agency added.
An anomaly review board led by NASA has been investigating what happened ever since, and a further update is expected when testing finishes at the end of this week.

It follows further delays and additional expenses caused by the COVID-19 pandemic, according to NASA.
The aim is for the orbiting telescope to succeed both the Hubble Space Telescope which was launched in 1990 – and is expected to be in service until 2040 – and the Spitzer Telescope which was launched in 2003.
When the launch does take place it will herald a new era in space science, and offers NASA the opportunity to publish new images such as those captured by Hubble which have inspired so many people’s imaginations.
The James Webb Space Telescope (JWST) is intended to “examine every phase of cosmic history: from the first luminous glows after the Big Bang, to the formation of galaxies, stars, and planets to the evolution of our solar system”.
By examining infrared light the JWST will directly observe a part of space and time (which are not distinct qualities according to special relativity) that humanity has never been able to see before.
It will gaze deep into the past, back when the very first stars were forming over 13.5 billion years ago – because it is able to see the light emitted back then which has been stretched or “redshifted” by the continual expansion of the universe.
The JWST is the largest and most powerful space science telescope ever constructed by NASA, and after being launched it will travel to an orbit about a million miles away from Earth before undergoing six months of commissioning in space.
During this period its mirrors and sunshield will unfold, and its smaller systems will need to be brought online too – it will need to be cooled, aligned, and calibrated.
Once all this is done, astronomers around the world will be able to use the telescope to conduct scientific observations and broaden humanity’s understanding of the universe.
The swimmer who was the first victim in the 1975 blockbuster Jaws has died.
Susan Backlinie died in her home in California at the age of 77, according to her agent. Her death was first reported by The Daily Jaws website.
The opening scene of Steven Spielberg‘s classic features Ms Backlinie running along the beach and before diving into the water and skinny dipping.
Her character Chrissie Watkins is then suddenly pulled under the water and she screams as she is violently attacked by an unseen great white shark.
Ms Backlinie had been a champion swimmer when cast in the film. She told The Palm Beach Post in 2015 that Spielberg told her: “When your scene is done, I want everyone under the seats with the popcorn and bubblegum.
“I think we did that,” she said.
In the documentary, Jaws: The Inside Story, Spielberg called Ms Backlinie’s sequence “one of the most dangerous” stunts he’s ever directed.

“She was actually being tugged left and right by 10 men on one rope and 10 men on the other back to the shore, and that’s what caused her to move like that.”

It marked the first time a genetically modified pig kidney was transplanted into a living patient. Surgeons said they believed the organ would last for at least two years.
Slayman’s family announced his death yesterday, thanking the doctors who carried out the world-first surgery for their “enormous efforts”.
They said the animal-to-human transplant – known as a xenotransplant – gave them “seven more weeks with Rick, and our memories made during that time will remain in our minds and hearts”.
The transplant team at Massachusetts General Hospital (MGH) said they did not have any indication he died as a result of the transplant.
Slayman, from Weymouth, Massachusetts, previously had a kidney transplant at MGH in 2018, but had to go back on dialysis last year after it showed signs of failure.

As he needed frequent procedures as a result of dialysis complications, his doctors suggested a pig kidney transplant.
His family said Slayman wanted to undergo the procedure to give hope to those on waiting lists for transplants, adding: “Rick accomplished that goal and his hope and optimism will endure forever.”
Pig kidneys had previously been transplanted into brain-dead donors, but only temporarily. Two men have also received hearts from pigs, with both dying within months of their prodecures.
More than 100,000 people are on the transplant waiting list in the US – most need a kidney, but thousands die waiting.
In the UK, the NHS said that in the year to March last year, there were 6,959 patients waiting for an organ transplant.
It said 439 patients died while on the active list waiting for it and a further 732 were removed from the transplant list, “mostly as a result of deteriorating health and ineligibility for transplant”.
Oprah Winfrey has admitted playing a role in perpetuating diet culture during her career and said a dieting item from a 1980s show was one of her “biggest regrets”.
The 70-year-old star – who has been ranked among the most influential women in the world – has been open about her struggles to maintain a healthy weight and attempts to lose weight.
In March she said “making fun of my weight was a national sport” for more than two decades.
In comments reported by NBC, Sky’s US partner, the talk show host told a livestream and live audience: “I want to acknowledge that I have been a steadfast participant in this diet culture through my platforms, through the magazine, through the talk show for 25 years.
“I’ve been a major contributor to it. I cannot tell you how many weight loss shows and makeovers I have done and they have been a staple since I’ve been working in television.”
But she admitted an item on a 1988 edition of The Oprah Winfrey Show was one of her “biggest regrets” when she rolled a wagon of fat on to the stage to represent the weight she had recently lost thanks to a liquid diet and exercise.
She had starved herself for months, she said, admitting that it “sent a message that starving yourself with a liquid diet and set a standard for people watching that I, nor anybody else, could uphold. The very next day, I began to gain the weight back.

“I own what I’ve done, and now I want to do better.”
Winfrey was speaking on Thursday at an event organised by WeightWatchers, whose board of directors she joined in 2015, before saying in February she was leaving.

In 2016, she used an interview in the magazine O to reveal she had lost 12kg, sharing the cover with nine other woman to celebrate their “best body”.
In the issue, Winfrey said, “It was my idea to share the cover with other women who are on the same journey that I am. My own struggles with the scale are well known. I’ve never believed in hiding them.”
In December, she told People she had started taking a weight loss drug, saying she used it “as I feel I need it, as a tool to manage not yo-yoing.
“The fact that there’s a medically approved prescription for managing weight and staying healthier, in my lifetime, feels like relief, like redemption, like a gift, and not something to hide behind and once again be ridiculed for.”
