Hello, welcome to the program. This is News Hour from the BBC World Service and

we're coming to you live from London. My name's Paul Henley. In a moment

with just hours to go until the US presidential debate

between Kamala Harris and Donald Trump we'll hear from the King's the key

swing state of Pennsylvania that's our main story this evening. Also on the program a

SpaceX rocket has blasted off from Florida. It's crewed by non-professional

astronauts. What are they trying to achieve while they're in space?

There are so many new things that they're doing on this mission.

For instance, they're going three times the altitude of the space station and that hasn't happened since we went to the moon.

They're going to do the very first commercial space walk, which is extremely risky.

They'll be in new spaceuits for the spacewalk.

This is a mission that has a lot of added risk to it.

We also have the second of our reports from inside Afghanistan on how life has changed for millions of women under Taliban rule.

Now the first and potentially the only televised US presidential debate between Kamala Harris and

Donald Trump takes place

those swing states to which both candidates have been making repeated visits.

On this program we're going to be hearing in detail from one of those crucial people,

the undecided voters.

We'll hear too about the role of Generation Z, and will have an overview from a political reporter on the difference

this TV encounter might make to the whole competition.

First, his report from the BBC's Tom Batemaneman who's been meeting voters in Western Pennsylvania.
