 Arsenal medical director Dr Gary O'Driscoll has opened up on the devastating Achilles injury that Laurent Koscielny suffered in last season's Europa League semi-final

 Heading to Atletico Madrid following a 1-1 draw at the Emirates, the Gunners needed to pull off an incredible result in the Spanish capital if they were to make it to the final in Lyon at the end of May

 However, tragedy struck inside the opening few minutes with the French defender going to ground under no challenge, with Diego Costa the closest player to him

 In agony on the ground at the Wanda Metropolitano, it was obvious that something was seriously wrong with the long-serving centre-back as O'Driscoll rushed onto the pitch

  Speaking in the Laurent Koscielny: Stronger documentary, the medical director said: "Laurent was in significant pain and he said to me: 'He kicked me! He kicked me!'  "Diego Costa came to us and tapped me on the shoulder and said: 'I did not kick him, I heard a snap

'  "The fact that there was an audible snap on the pitch and there was no-one near him just indicated that this was a serious injury and one that hadn't been caused by a foul

"  Lying on the bed in the changing room as the team came in at the interval, O'Driscoll revealed that Antoine Griezmann, Koscielny's international teammate, came to see his fellow countryman

 "There were three or four of us in the dressing room and Laurent was lying on the bed, close to tears," he said

"It was an extremely emotional moment.  "The half time whistle went and suddenly all the players came in

 "The level of endearment, respect and love for Laurent was apparent straight away

 "All the players came over, there were lots of hugs and then the team went off for the team talk

 "I stayed with Laurent and then there was a very emotional moment when one of the players from the opposition came in, it was Antoine Griezmann

 "He walked in, went over, put his arm around him and the two of them had a fond embrace and a cuddle, and it was a prolonged one

 "Griezmann didn't say to me, 'how bad is this?'  "They looked at each other and they almost knew what the implications were

 "I think that made a big impression on Laurent. I think he knew that not only was he cared for and loved in the dressing room, but also that people outside were all thinking of him and were all caring about what was going to happen next, while also being aware that this is probably the end of his World Cup

What Science Was Actually Done on the Moon? | Apollo - Duration: 5:50.

After Apollo 13's near disaster, the fate of the lunar program was back on rocky ground.

Apollo 14 was scheduled to launch before the end of the year and it would provide the most

extensive scientific exploration yet,

but if it was ever going to take off,

investigators needed to determine what exactly went wrong on Apollo 13.

And NASA had to make sure that it wouldn't happen again.

The investigation found that the near-disaster was a combination of

human and design error.

The source of the explosion was an oxygen tank inside the Service Module.

Before it made it onto Apollo 13, the tank went through a series of problems.

In 1968, it was scheduled to fly on Apollo 10

but was accidentally dropped on the ground before the mission.

After it passed a series of tests, it was cleared to fly on Apollo 13.

But then, in 1970, during pre-flight testing, the tank wasn't emptying as it should.

So, to gasify the liquid oxygen, technicians turned on the tank's heater using 65 volts

which should have been fine since the spacecraft components were all modified

to handle increased power in 1965.

But unfortunately, the thermostatic switch within the oxygen tank

was still geared for just 28 volts.

It was later found that the excess power caused the switch to weld shut, and the temperature

inside the tank rose to over 500 degrees Celsius and damaged insulation on the wires inside

the tank, leaving a high risk for a short circuit.

From the outside, though, everything appeared to be... good enough to fly.

So on April 11, 1970 Apollo 13 essentially lifted off with a time bomb inside the service module.

After the near disaster, NASA had to make major structural changes

to the Command-Service Module and the Lunar Module.

Improvements were also made to the astronauts airtight spacesuits

and the lunar surface experiment equipment.

Apollo 14 would be the first crewed mission to put these upgrades to the test.

NASA selected Astronaut Alan Shepard as the mission's commander.

Almost ten years prior, Shepard became the first American in space during Project Mercury.

Apollo 14 would mark his triumphant return after a rare disease

kept him grounded for many years.

Joining Shepard, were rookies Edgar Mitchell and Stuart Roosa.

About nine months after Apollo 13, NASA was headed back to the moon.

Apollo 14 was en route to the Fra Mauro formation - a ridged region that was believed to be

made up of an ejecta blanket from a collision between a huge mass and the Moon.

This made it an ideal landing location for science.

But getting there wasn't as smooth as NASA hoped.

Once in lunar orbit, it took six attempts before the crew could dock the Command and Lunar Modules.

And then during the descent to the Moon, the lunar module signaled an abort.

Mission control and the astronauts worked through the problems though, and the crew eventually

pulled off a high precision landing within target range.

On the surface, Shepard and Mitchell attempted a trek to the rim of the Cone Crater, collecting

lunar rocks in their space wagon along the way.

They also measured the strength of the Moon's magnetic field, collected samples of the solar

wind and studied the properties of lunar soil.

Additional experiments were deployed that enabled scientists to monitor activity from Earth.

Some of these experiments would go on to detect lunar "moonquakes", providing information

about the internal structure of the Moon.

And others would study the lunar ionosphere and measure the precise distance

between Earth and the Moon.

Back on the CSM, Roosa conducted orbital science activities that measured regional variations

in the Moon's gravitational acceleration and the scattering of radar waves from the lunar surface.

Apollo 14 packed in more science than any mission before it,

pushing the astronauts to new extremes.

They collected over 40 kilograms of rocks and soil from the lunar surface including

this one nicknamed "Big Bertha."

And Shepard, the oldest man to get to the moon, set a new distance-traveled record on

the lunar surface equivalent to about 55 laps in an Olympic-sized pool.

But aside from the extensive experiments and massive terrain covered, Apollo 14 is best

remembered for this moment when Alan Shepard broke out a modified six iron and hit two

golf balls into the cosmic distance.

The astronauts then headed back to the CSM to begin their return to Earth.

Apollo 14 has a longstanding legacy linked to discovery.

The lunar samples returned have been studied for decades, helping scientists better estimate

the age and physical nature of the moon.

Photos from the mission verified the role of volcanism in the formation and modification

of lunar highlands and documented deep-space phenomena known as Zodiacal light and Gegenschein.

Seeds that were aboard the mission were planted around the world and have since grown into

living monuments of the third trip to the Moon.

Apollo 14 also validated the changes NASA made after the Apollo 13 disaster and demonstrated

that spaceflight challenges are solvable.

The next missions would build off this momentum, taking exploration capabilities

even further with the introduction of a new way for astronauts to explore the lunar surface.

If you want to learn more Apollo 13 and how NASA got the astronauts home safely,

 "Do you like it? I hope so," Pillsbury bake-off winner, Anna Ginsberg says to Winfrey as she takes her first bite

Instead of immediately answering, Winfrey smiles awkwardly at the audience.  "Just say yes," Ginsberg says nervously

After chewing for a bit longer, Winfrey finally responds.  "I do like it," Winfrey replies apprehensively

"I like it very much."  However, there was just a little something wrong with the recipe

"Did we add salt and pepper? I think we need salt and pepper," Oprah asks.  "No, there's no salt and pepper in it, but you can add it yourself," Ginsberg says back as the audience erupts in laughter

 "I often think about the time Oprah did a cooking segment with a woman whose chicken recipe won $1 million, and Oprah's jaw dropped when she tasted it and realized the lady didn't even add seasoning," Althouse captioned the tweet

 Within minutes, the moment went viral with many fans pondering the same question

 The tweet, of course, caught the eye of Winfrey herself, who then offered up an explanation

 "Okay, Spencer, I don't know whatever made you pull that tape out of a vault, but, made me laugh," Winfrey said in a video shared on social media Thursday

 "This is what I was thinking. I always wanted anybody who came on the show, no matter what they did, to have a good experience

And I also wanted to stay in my own truth while allowing them to have that good experience

"  "I was having a moment of trying to decide 'Do I want her to have a great time?… What is my moment of truth?'" Winfrey continued

 "Because the truth for me is that I'm used to having salt and pepper on my chicken

That's the truth. That's what I was thinking. This chicken needs some salt and pepper

"  Winfrey's hilarious confession comes after her best friend Gayle King spilled a sweet secret about their friendship

 On Thursday, Gayle, 63, appeared on Watch What Happens Live with Andy Cohen, where she revealed that she and Winfrey don't exchange Christmas presents

 "She has a rule, we don't exchange gifts because both of us feel we don't really need anything," King said

"We just like hanging out together."  King will be spending a lot of time with Winfrey this January

 As announced in June, the duo is planning on setting sail with more than 2,600 of their closest pals for a three-day "Girls' Getaway" cruise aboard Holland America's Nieuw Statendam ship

 The influential centre-back suffered a serious Achilles injury against Atletico Madrid in the Europa League last season

 He was stretchered off and subsequently missed out on playing for France at the World Cup in Russia

 O'Driscoll says the atmosphere behind the scenes was sombre at the Wanda Metropolitano Stadium

 "There were three or four of us in the dressing room and Laurent was lying on the bed, close to tears," he told Arsenal Player

 "It was an extremely emotional moment. "The half-time whistle went and suddenly all the players came in

 "The level of endearment, respect and love for Laurent was apparent straight away

 "All the players came over, there were lots of hugs and then the team went off for the team talk

 "I stayed with Laurent and then there was a very emotional moment when one of the players from the opposition came in, it was Antoine Griezmann

 "He walked in, went over, put his arm around him and the two of them had a fond embrace and a cuddle - and it was a prolonged one

 "Griezmann didn't say to me, 'How bad is this?' "They looked at each other and they almost knew what the implications were

I think that made a big impression on Laurent. "I think he knew that not only was he cared for and loved in the dressing room, but also that people outside were all thinking of him and were all caring about what was going to happen next, while also being aware that this is probably the end of his World Cup

" Koscielny made his long-awaited comeback for Arsenal against Qarabag FK in the Europa League on Thursday night

 "Yes, it was an important day for me," Koscielny told Arsenal's website. "It was the end of my rehab, so I am very happy to play today with my team, for this club, and to enjoy it with them on the pitch

 "I'm proud of myself. "You know in rehab it's difficult to be injured, because when you start rehab you have to re-learn how to walk, how to go step by step on the stairs

 "It's difficult at the beginning, because you look like you can't be back on the pitch

 "It was very emotional because you remember the first day when I was injured, the 3rd of May, and now we are on the 13th of December, and you have some flashbacks in your head about different periods you had during your rehab

 "I met a lot of people who helped me a lot, and so I'm very proud to know them now

 "There were some difficult moments, during this period. "But now I think I'm more calm and focused on what I want, and physically I'm OK

'Free Solo' Directors Reveal What It Was Like Filming 'The Greatest Athletic Feat Ever' - Daily News - Duration: 5:42.

When the directors of 'Free Solo' set out to document Alex Honnold's mission to make the 'impossible, possible,' they knew they were taking on the challenge of their lives

   Imagine trying to climb the infamous 2,900 ft sheer rock face of the Yosemite rock formation, with just your bare hands, shoes and some chalk? In other words, without being roped in by any standard rock climbing equipment

None. Nada. If you think that's absolutely crazy and a sure way to plummet to your death, well so did most of the elite rock climbing world, who were very familiar with who Alex Honnold was, and were astounded by his quest to climb El Capitan, which had never been "free soloed

" In fact, no one had even talked about daring to try it.    But that was Honnold's dream after he began free solo climbing as a shy California teenager, and went on to successfully complete over 1,000 free solo climbs

Documentary filmmakers Elizabeth Chai Vasarhelyi and Jimmy Chin, an accomplished mountain climber himself, were fascinated by the challenge of following Honnold's quest, but were also torn about whether they could affect the outcome, they told Hollywoodlife

com in an EXCLUSIVE podcast interview. "We never had to convince him to do the film," Elizabeth said

"Everyone involved was very committed… but the existential question at the heart of the film was, 'if we're filming, is he more likely to fall?'… Ultimately, it would come down to whether we believed in Alex

And whether we trusted his judgement and whether he trusted us to do our jobs the right way

"  That meant that as Honnold spent months preparing by climbing El Capitan, roped in, in the traditional way, with expert climber Tommy Caldwell, who had climbed the face for 20 years, the film crew was also meticulously preparing

Chin, who has climbed Mt. Everest, and Vasarhelyi, who are married and have two little girls, assembled a very unique crew

Every member of the video team had to be elite, professional climbers and also world class cinematographers

 "Meaning, there's only a few people in the world who could film Free Solo," explained Chin

"We spent well over 30 days just on El Cap, not to mention all these other formations

We went to work every morning and were rappelling over the edge on a 3,000 foot wall

"  Filming was therefore, not for the faint hearted as the Free Solo film team followed Alex's months of practice, plus his growing relationship with his first ever serious girlfriend, Sanni McCandless, plus Chin and Vasarhelyi, got Honnold to open up about his relentless drive and yes, his fears

"Any sort of mistake is fatal, " said Chin. And Alex climbed it in three hours and 56 minutes without any kind of safety equipment

Really, it's considered the greatest athletic feat of all time. Because climbing at that level without a rope takes total commitment and is truly, even for seasoned climbers, unthinkable

"  Honnold feels compelled to explain in the film that he loves life and has no death wish

He believes that his meticulous preparation lowers his risk of making a deathly move

"I try to expand my comfort zones by practicing the moves over and over again. Move through the moves so they aren't scary anymore," he said, not that you as a viewer will find what he does any less terrifying

   What's driving Honnold we learn, is his quest for perfection. "If you are seeking perfection, free soloing is as close as you can get and it does feel good to feel perfect… for a moment," he shares

 Vasarhelyi and Chin, did their own part to mitigate the risks of capturing his climb on film

Chin had safety systems plus two or three backups  in place for his cinematographers

"Plus, we had to be really careful… if you dropped a lens cap it could fly several hundred feet and hit Alex," explains Chin

The crew had to carry 50lb packs with all their camera equipment, ropes and food and water for the day, plus they had to be able to move very quickly since Alex was such a fast climber

 Ultimately, the project took two and a half years and yes, SPOILER ALERT, Honnold astoundingly accomplished this miraculous feat, and the documentary is breathtaking

On the day that Alex actually climbed, it was "a terrifying, terrifying experience… we had to always remind ourselves of why we believed in Alex and how we trusted him and trusted his judgement," admits Vasarhelyi

"On the day of, it was this weight that you can't shake off, so when he made it through the hardest parts there was a certain moment where it was just understood that you were witnessing one of the greatest athletic achievements of all time

"  Yes, and now you can too.  Listen to our Holllywoodlife podcast interview on itunes and I highly recommend seeing, Free Solo
