There are thousands of human remains in Britain's museums to analyse. Each has their own tale to tell. The new discovery will enable scientists to hear their stories and rewrite the history books.

They thought the spacecraft would emerge, but they didn't know whether it would emerge intact. But so far, so good. It sent back a little bleep to say that it was in good health. It won't be sending back any data for a few days. We'll have to wait until the 1st of January.

But a huge sigh of relief because not only has it broken records, it's hopefully gathered new data on how our sun actually works.

That's right. You'd imagine that this thing that's up in the sky every day, we know so much about. Astronomers have been studying it for centuries. There have been so many missions that have gone. But none have got so close. The Parker Solar Probe came within four million miles. Now, that seems like a very, very long way away. But in space terms, that's really close, touching the sun, if you like.

And so it needed a powerful heat shield, an experimental heat shield to protect it. And believe it or not, so close to the sun, somehow the instruments were kept at room temperature. I don't know where this room was, but it must be a pretty hot room. But the long and short of it is that the instruments are intact. We'll have to wait and see the data.

Because sometimes during a solar eclipse, you must have seen pictures of it, you see the sun's atmosphere. Normally... You know, you don't look at the sun, but pictures of it show this kind of featureless disk in the sky. But when the moon passes overhead and covers that disk, you see this beautiful shimmering atmosphere and a few red things emerging from it.

And then you see what the sun is really like, this beautiful but violent processes going on on it. And it's understanding those processes that the Parker Solar Probe is there. There are magnetic fields that twist and turn automatically. the fiery surface, the corona, the sun's atmosphere.

The sun also spits out a solar wind, which comes over and hits the earth, cause those wonderful northern lights that we experience from time to time. So a lot to learn, a lot to look forward to in the coming days, weeks and months.

Butch Wilmore and Sonny Williams blasted off in June on an experimental spacecraft built by Boeing called Starliner. On the way there, there were a few issues with their thrusters. And everyone said it was going to be fine. And NASA just needed to check it out. After those eight days had gone by, they said they still needed to check things out. And then days turned to weeks later.

Weeks turned to a month. And then they said they'd have to wait until February because they couldn't be sure that they could get them back safely. And so much to Boeing's irritation, I suspect, they were told that it would be their arch rival SpaceX that would use their space capsule, the Dragon capsule, to bring them back in their next crew rotation. Alas, SpaceX 2 has had an issue.
