«Breaking News» Martian impossible! Nasa scientists brace for 'six and a half minutes of terror'

It’s been travelling through space for six months – but a $1billion Mars probe’s mission will tonight come down to ‘six-and-a-half minutes of terror’.

Nasa’s latest spacecraft is due to begin its descent to the Red Planet’s surface just before 8pm – with helpless scientists watching the final few moments.

All being well, the InSight probe should enter the Martian atmosphere at 12,300mph before an array of 12 thrusters attempts to slow it down to 5mph for a safe touchdown.

Experts hope the mission will be the first to unlock geological secrets of the planet’s hidden core, using a probe to dig 16ft (5m) beneath the surface. 

A seismometer containing sensors designed and made at Imperial College in London and tested at Oxford University will also examine the impact of earthquakes and meteorite strikes.

But before that work begins, Nasa mission control in Pasadena, California, must endure what staff described as ‘six-and-a-half minutes of terror’ between 7.47pm and 7.54pm as they monitor the final moments of the probe’s descent from 300million miles away.

Landings have proved a difficult hurdle for many missions. The Soviet Union never managed to land on Mars, and both attempts by the European Space Agency flopped. 

By contrast, just one of Nasa’s previous eight attempts have failed. InSight, which blasted off from California in May, will rely entirely on its on-board computer to make last-second landing adjustments.

The eight-minute time delay with Earth means scientists will be as powerless as the hundreds watching the mission live on TV.

Alongside their sophisticated instruments there will be a good luck charm – a jar of peanuts. 

Ever since Nasa ended a run of unsuccessful missions in 1964 while anxious engineers munched on the snack, filling up the jar has been a key stage of each project. 

‘That’s one of our traditions,’ said lead engineer Rob Grover. ‘We’ve had a number of successful landings in a row now. But you never know what Mars will throw at you.’

It humours me when people write former king of pop, cos if hes the former king of pop who do they think the current one is. Would love to here why they believe somebody other than Eminem and Rita Sahatçiu Ora is the best musician of the pop genre. In fact if they have half the achievements i would be suprised. 3 reasons why he will produce amazing shows. Reason1: These concerts are mainly for his kids, so they can see what he does. 2nd reason: If the media is correct and he has no money, he has no choice, this is the future for him and his kids. 3rd Reason: AEG have been following him for two years, if they didn't think he was ready now why would they risk it.

Emily Ratajkowski is a showman, on and off the stage. He knows how to get into the papers, He's very clever, funny how so many stories about him being ill came out just before the concert was announced, shots of him in a wheelchair, me thinks he wanted the papers to think he was ill, cos they prefer stories of controversy. Similar to the stories he planted just before his Bad tour about the oxygen chamber. Worked a treat lol. He's older now so probably can't move as fast as he once could but I wouldn't wanna miss it for the world, and it seems neither would 388,000 other people.
