A Space Traffic Management system

  • does not actually exist at present.

Problems in developing effective Space Traffic Management

  • Satellites are now quite

Space Traffic Management
In today's astronomy lecture, I'm going to talk about the need for a system to manage the movement of satellites and other objects in orbit around the Earth. In other words, a Space Traffic Management system. We already have effective Air Traffic Control systems that are used internationally to ensure that planes navigate our skies safely. Well, Space Traffic Management is a similar concept, but focusing on the control of satellites.
The aim of such a system would be to prevent the danger of collisions in space between the objects in orbit around the Earth. In order to do this, we'd need to have a set of legal measures, and we'd also have to develop the technical systems to enable us to prevent such accidents.
But unfortunately, at present we don't actually have a Space Traffic Management system that works. So why not? What are the problems in developing such a system?
Well, for one thing, satellites are relatively cheap these days, compared with how they were in the past, meaning that more people can afford to put them into space. So there's a lot more of them out there, and people aren't just launching single satellites but whole constellations, consisting of thousands of them designed to work together. So space is getting more crowded every day.
But in spite of this, one thing you may be surprised to learn is that you can launch a satellite into space and, once it's out there, it doesn't have to send back any information to Earth to allow its identification. So while we have international systems for ensuring we know where the planes in our skies are, and to prevent them from colliding with one another, when it comes to the safety of satellites, at present we don't have anything like enough proper ways of tracking them.
And it isn't just entire satellites that we need to consider. A greater threat is the huge amount of space debris in orbit around the Earth – broken bits of satellite and junk from space stations and so on. And some of these are so small that they can be very hard to identify, but they can still be very dangerous.
In addition, some operators may be unwilling to share information about the satellites they've launched. For example, a satellite may be designed for military purposes, or it may have been launched for commercial reasons, and the operators don't want competitors to have information about it.
And even if the operators are willing to provide it, the information isn't easy to collect. Details are needed about the object itself, as well as about its location at a particular time – and remember that a satellite isn't very big, and it's likely to be moving at thousands of kilometres an hour. We don't have any sensors that can constantly follow something moving so fast, so all that the scientists can do is to put forward a prediction concerning where the satellite is heading next.
So those are some of the problems that we're facing. Let's consider now some of the solutions that have been suggested. One key issue is the way in which information is dealt with. We need more information, but it also needs to be accessible at a global level, so we need to establish shared standards that we can all agree on for the way in which this information is presented. We already do this in other areas of science, so although this is a challenge, it's not an impossible task. Then, as all this information's collected, it needs to be put together so it can be used, and that will involve creating a single database on which it can be entered.
As we continue to push forward new developments, congestion of the space environment is only going to increase. To cope with this, we need to develop a system like the one I've described to coordinate the work of the numerous spacecraft operators, but it's also essential that this system is one that establishes trust in the people that use it, both nationally and at a global level.
One interesting development ...

Mình có: prevent the danger of collisions in space between the objects in orbit around the Earth >> ngăn chặn nguy cơ va chạm trong không gian giữa các vật thể trên quỹ đạo quanh Trái Đất = improving safety.

have a set of legal measures develop the technical systems to enable us to prevent such accidents >> có một loạt các biện pháp pháp lý + phát triển các hệ thống kỹ thuật để cho phép ngăn chặn những tai nạn như vậy = would aim to set up legal and (1) ___ ways of improving safety.
