The Excerpt
SPECIAL | Space junk: the impact of global warming on satellites

Well, we've seen recently, certainly in the news, lots of instances of space debris that makes its way all the way to the ground and maybe poses a hazard to people on the surface. That is certainly a concern, and it's something that I think will constrain our space activity. It's important to, one, be able to understand what will these satellites do as they're burning up in the atmosphere.

SPECIAL | Space junk: the impact of global warming on satellites

Will they burn up completely? In a lot of cases, we thought they would, and they're not in practice. So that's a concern, and that's something that the space industry needs to work on. The other component is we need to sort of better coordinate between all of the decision makers and all the people that need to know the information that we have available.

So if we have a satellite that's reentering that may not make it to the ground, we need to do a better job of coordinating with airline pilots, with people in the ground that may be impacted in advance. And that's certainly a concern, I think, for people's safety.

Obviously, it's a pretty low risk just because we don't have satellites reentering all the time and the Earth is very big and it's mostly water. So we haven't seen an issue yet. But as we're launching more things into space and as the atmosphere is removing more of those objects, we're going to start to see more of these reentries happen. So it's important to get a grip on that problem.

The mega constellations are a new trend in the way that we operate satellites. It was initially driven by companies like OneWeb and SpaceX. Today, SpaceX's Starlink constellation is over 60% of all of the active satellites in orbit. And they operate, at this point, many thousands of satellites in a very tight altitude regime.

And they are designed in a very structured way, so they can fit a lot of satellites in a very tight space. The idea with these mega constellations, in particular, these large constellations in low Earth orbit, is mostly to provide broadband internet to people on Earth. And the reason that they are in low Earth orbit, very close to the surface, is because we have pretty low latency.

So for internet, I can communicate with a satellite very quickly, whereas historically, our satellites for internet had to be really far away. And so it took a long time for that signal to propagate. These constellations are an entirely new means of operating in space. And so the rules are fundamentally changing.

SPECIAL | Space junk: the impact of global warming on satellites

We don't have a lot of regulations in the way that we use space, especially in the way that we use frequency spectrum to be able to communicate with our satellites. So there are a lot of constraints on operations that these constellations are now starting to stress because we've never had to think about populations in space this large.

The Excerpt
SPECIAL | Space junk: the impact of global warming on satellites

You know, like I said, space is a shared resource for everyone. Everyone stands to benefit from it. I think in the last few years, we've seen that the cost to access space has gone down dramatically. So that's cost to build a satellite, to launch a satellite and to operate a satellite. I think that that's really good for the players that have never had access to space before, right?

We have this new accessibility to space that didn't exist before. We have these pathways that are well-defined.
