Nasa is less than 24 hours away from launching the James Webb Space Telescope, which the US space agency hopes will unlock the secrets of the early universe.
The launch is scheduled for 12.20pm GMT (7.20am EST) on Christmas Day, with a live stream available on Nasa’s website shortly before lift-off.
All sorts of last-minute issues could hamper the launch of the $10 billion observatory, which was previously pushed back from 24 December due to poor weather conditions at the launch site in French Guinea.
Nasa administrator Bill Nelson warned ahead of the launch that “over 300 things” could go wrong and scupper the launch, with officials saying during a news conference this week that there was an intermittent communication delay between the rocket and telescope.
Once in space, the James Webb telescope will attempt to look back in time 13.7 billion years towards stars and galaxies formed during the early stages of the universe’s creation.
