Update: The jump is now taking place on Tuesday lunchtime around 1.30pm
Austrian daredevil Felix Baumgartner's attempt to skydive from an incredible 23 miles up and break the sound barrier on the way down has been delayed by unsuitable weather.
The mission, which is taking place above New Mexico, was expected to launch at around 6am Mountain Daylight Time – that’s 1pm in the UK - on Monday, but has now been put back until Tuesday.

The team explained that the delay was caused by a forecast for wind speeds to be above acceptable levels for a safe launch on Monday morning.
The previous record for the highest freefall was set by US military pilot Joe Kittinger on 16 August 1960.
He leapt from a helium-filled balloon from 19 miles up and reached 600mph on the way down.
To say that jumping from even higher up is a risky undertaking is an understatement.
For starters, Baumgartner, also known as “Fearless Felix”, could go into a spin, haemorrhage his eyes and get a blood clot on his brain – or his blood might “boil” if his suit rips.

The 43-year-old from Austria may also break his neck.
But the jump has been meticulously planned over the past five years.
He’s already made two test jumps from 15 and 18 miles - and he’s using state-of-the-art kit.
For example, if he’s rendered unconscious an emergency parachute will deploy automatically.
His journey down will be one that no skydiver will be familiar with.
He’ll be so high up that he won’t even have a sensation of falling, because there’s hardly any atmosphere.
Kittinger reported that his jump suit didn’t even ripple during the first few minutes of the fall.
Many people will wonder, of course, whether Felix really will be “Fearless” on the big day.
According to Dr Rhonda Cohen, Sport Psychologist at Middlesex University, his moniker isn’t entirely accurate.
She told Huffington Post UK: “People who do extreme things do so because they are able to weigh up the risk and the safety factor. They can calculate the extent of the danger. Will Felix be scared? Of course - the dangers are still there – risk to health and life.
“However, the gamble is that focusing in on the goal of achieving a record will outweigh the possible death. So like a gambler – it’s weighing whether there is a greater chance of success than a risk of death. People in extreme sport examine that balance continuously.”
Dr Cohen believes that what motivates the daredevil is the challenge of redefining the limits - and simply getting a buzz.
She added: “People in extreme enjoy pushing the limits – it’s that sense of being really frightened but being really excited at the same time. It is the sense of challenge in one hand and the sense of the unknown in the other.”
