SPACEX and Blue Origin launch: Falcon 9 rocket launch delayed and new shepard forced to cancel

A second attempt to launch the SpaceX Falcon 9 rocket will take place in Florida today, as Elon Musk’s private space firm aims to deliver a spy satellite into orbit for the US Air Force.

It is the first time SpaceX is launching a satellite for the US military, following an $83 million contract with the Air Force.

The satellite launch is scheduled for 9.07am EST (2.07pm GMT) from Cape Canaveral Air Force Station.

It will be the first of three major rocket launches today, with Jeff Bezos’s Blue Origin set to send its New Shepard capsule into the skies above West Texas just 19 minutes later.

A third launch is then planned from multinational satellite firm Arianespace and the US-based United Launch Alliance.

Weather in Florida suggests a high chance the SpaceX launch will go ahead as planned today, according to Kennedy Space Center.

In attendance at the Cape Canaveral launch site is US Vice President Mike Pence, who calls the SpaceX mission "an important day for American leadership in space."

Speaking to the Associate Press earlier, two officials say the VP may also be making an announcement later today about Donald Trump's proposed Space Force programme.

Here's what Pence has previously said about the space initiative: "Trump is committed to preparing for the next battlefield where America’s best and bravest will be called to deter and defeat a new generation of threats to our people and our nation…The time has come to establish the United States."

Blue Origin also seems on track for the second launch of the day, with the New Shepard rocket on the pad beneath blue skies in West Texas.

So with less than an hour to go until the SpaceX launch, what can we expect from the landmark launch?

Firstly, there will be a 26-minute launch window beginning at 9.11am EST (2.11pm GMT).

Mission requirements will mean there will not be an attempt to land Falcon 9’s first stage rocket after launch.

The payload is a GPS III satellite, which the US Air Force says “will augment the current constellation of 31 operational GPS satellites.”

SpaceX has just announced a new launch time of 9.34am EST (2.34pm GMT), owing to wind levels. 

This puts it at the end of the scheduled launch window and pushed it behind the Blue Origin launch.

Should it be cancelled, there is a backup window scheduled for Wednesday, 19 December at 9.07am EST (2.07pm GMT).
