The james webb space telescope is now manoeuvring its primary mirror into position. at 6.5 metres wide, it's a massive bit of kit — and crucial to the telescope working for years to come. the mirror�*s great size will enable it to gather the faintest signals in the most minute detail. our science editor, rebecca morelle, explains. travelling through space and getting ready for its mission to begin. the james webb space telescope successfully launched nearly two weeks ago. it's a successor to hubble and will revolutionise our view of the universe. webb has the potential to blow people away,...

La launch, from a european space port. a reminder that this is not just a nasa mission, this is a global international partnership with europe and the canadian space agency as well. but despite this tremendously successful launch, this is really only the beginning of the webb space telescope's journey to go into an orbit with the sun about a million miles away from the earth. the next 29 days, that is what nasa calls the 29 days on edge. you've heard about the 7 minutes of terror with the mars rover. webb gets 29 days on edge as this telescope unfolds origami. and during that time, there are m...

To finally see it go up there. at the time we were reporting the launch, i remember scientists describing this business they've just completed is a bit like "origami in space". can you explain, first of all, why can't the mirror have just gone up open? there is one very big problem, which it that the jwst has a 6.5—metre—wide mirror and a rocket is about three metres wide. so, you can't fit something that big inside a tiny rocket. so they had to do some creative origami and fold it up, and put it inside this rocket. it also had this absolutely massive sun shield — so this was five layers...

In space. can you explain, why can't the mirror havejust in space. can you explain, why can't the mirror have just gone up open? there is one very big problem that it has a 6.5 wide metre mirror and a rocket is about three metres wide. we cannot fit something that big inside a tiny rocket. they had to do some creative origami and fold it up and put it inside this rocket. it also had this absolutely massive sun shield. so this was five layers of foil. each layer is the size of a tennis court. there is no way you could fit that in a rocket so they had to full do it all up and send it into space ...

Having successfully completed the unfolding of its sun shield, the james webb space telescope is now manoeuvring its primary mirror into position. at 6.5 metres wide, it's a massive bit of kit and crucial to the telescope working for years to come. our science editor rebecca morelle explains. travelling through space and getting ready for its mission to begin. the james webb space telescope successfully launched nearly two weeks ago. it's a successor to hubble and will revolutionise our view of the universe. webb has the potential to blow people away, even people who are used to hubble. and i ...
