Elon Musk's company SpaceX and NASA are set to make a second attempt to launch astronauts into space later today - and you may be able to catch sight of the rocket.
Brits were left disappointed on Wednesday after the rocket launch in Florida was aborted just 16 minutes before the scheduled take-off due to stormy weather.
While the sun is shining in Greater Manchester, have your fingers crossed for the manned mission, dubbed Demo-2, because the forecast in the US is looking uncertain.
The mission will see the Falcon 9 rocket carrying the Crew Dragon capsule set off from launchpad 39A at the Kennedy Space Centre and head for the International Space Station.
Strapped inside will be experienced NASA astronauts Robert Behnken, 48, and Douglas Hurley, 43 who will be making history as this is the first time astronauts will be launched into orbit from US soil in nine years, and it's also a first for a private firm.
For Saturday's launch, mission managers have this time chosen to lift-off an hour earlier at around 3.22pm EDT - which is 8.22pm UK time.
If it all goes to plan, skywatchers in the UK could see the rocket flying over the UK 15 minutes after lift-off at around 8.37pm.
However, because of the earlier schedule, it will likely be too light to see the capsule coming overhead at that time.
There is hope as it passes the UK for a second time at around 10.15pm, which will make for a better viewing with darker sky conditions, however the vehicle will be very low on the horizon in the southwest.
Shortly after lift-off, the rocket will separate into what is called a first stage and a second stage. The first will return to a SpaceX landing ship sationed in the Atlantic Ocean off the coast of Florida, while the second part of the rocket continues the journey with the Crew Dragon.
Once in orbit, the Crew Dragon will then separate from the second stage and dock with the space station 24 hours later.
The pair of astronauts will test the Crew Dragon’s environmental control system, the displays and controls, and the manoeuvring thrusters.
Demo-2 is a demonstration for SpaceX to show their ability to ferry astronauts to the space station and back safely. It’s the final major step for the firm’s astronaut carrier to get certified by Nasa’s Commercial Crew Programme for more long-term manned missions to space.
