At TFL, we're making journeys safer for everyone, and that includes improving safety on London's roads.

That's why we and London boroughs are lowering more speed limits to 20 miles per hour,

because 20 miles per hour roads have already reduced collisions resulting in deaths or

serious injuries by 24%. That is how we're making journeys in London safer and brighter for everyone.

Such TFL improvement plan to the Mayor of London and TFL every journey matters.

Voyager 1 and Voyager 2 launched 1977.

Voyager 1 Bob Zimmerman educates me is outside of the solar system, outside the bow wave.

This is 13 years to celebrate behind the black, and a dominant theme in those years has been

the fate of Voyager 1 and 2. Why? Because of the original Star Trek movie that turned on,

I won't ruin it for you, a plot about Vigia himself. Vigia 1, Vigia 2 was never exact.

Now we have up to date news of Vigia 2. Excuse me, Voyager 2. Bob, what's happened?

If this might be bad news, it might actually be the end of the mission, might not. We have to cross

a thing, isn't hope. But in sending out planned commands to Voyager 2, which is kind of outside the

solar system into planetary space, it's along the edge of the heliosphere, and depending on the

solar wind, sometimes it washes back over Voyager 2, and it's back in the solar system, and other

times it's out, it's mostly out. But they sent out planned commands to Voyager 2, and unfortunately

the commands had some error, and it caused the antenna to point two degrees away from Earth,

not directly at the Earth, and we're talking about billions of miles here, so the amount of

margin of error is significant. There's a very small margin of error, you've got to get it right,

and so because it's not lined up with the Earth, they've lost contact with Voyager 2 completely.

Does this mean its mission is ending? Maybe, but maybe not. The spacecraft is programmed that every
