My Lords, this is a historic moment for me because this is when I take the Liberal Democrats into space. As noble Lords will realise, particularly the Liberal roots of our party are based on pavement politics—picking up rubbish and keeping the streets clean—and this is my attempt to be a first mover politically on this by making it clear that we are the party that is determined to clean up space as well as go there.
That ambition apart, this is a very serious matter. Again, since I became involved in this, I have taken to watching the various documentaries about what is going on in space. Quite frankly, it is frightening how much rubbish is up there. It is not known who owns it, what the responsibilities are, how we get it down, and so on—at a time when we are told, and I believe, that we are only in the foothills of developing space in an economic way. There is a lot more going up there and the Bill needs to put responsibility on those who send things into space for having a clear idea about how and when they should come down in an environmentally friendly and safe way.
As of 5 July 2016, United States Strategic Command tracked a total of 17,852 artificial objects in orbit above the earth, including 1,419 operational satellites. Furthermore, more than 170 million pieces of debris smaller than 1 centimetre, about 670,000 pieces of debris sized 1 to 10 centimetres, and around 29,000 larger pieces of debris were estimated to be in orbit.
Space debris poses a risk to unmanned spacecraft, manned spacecraft and even the earth itself. We want to make sure that the Bill includes that responsibility, and perhaps create another new industry from this. On one of my viewing nights I saw that work was being done on sending up a kind of—it shows my age if I call it a hoover—Dyson to pick up some of this debris and bring it back safely. It is a very real challenge, which is worthy of consideration in the Bill.
