Last night, Blue Origin's new Glenn rocket exploded on the launch pad during a test in Cape Canaveral, Florida.

The company, owned by Jeff Bezos, said no one was injured and all personnel were accounted for.

But the rocket has a crucial role in NASA's Artemis program to return American astronauts to the surface of the moon.

Here to walk us through what happened and its significance is our science correspondent,

Miles O'Brien.

Miles is always good to see you.

This was a massive explosion, though.

The company said there was an anomaly during a test.

What happened?

You might call that a euphemism, Omna, anomaly?

Yes, that was a major malfunction for sure and quite an impressive

sight. First of all, let's be clear, nobody got hurt. Everybody was a long way away from this

rocket as they were conducting what they call a hot fire test, which is light up the engines,

but don't release the rocket, see how everything goes.

Obviously, things did not go well.

They will investigate it.

They'll figure out what it is.

Was it one of the engines?

Was it something else?

A lot of plumbing has to work well on a rocket in order for it to fly safely.

But crucially here, Omna, the issue is the destruction of the launch pad.

That is a big deal because they are complicated structures. It takes time to build them and to
