B. TRANSCRIPT

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. Q31

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 daysQ32 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. Q33

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 identificationQ34 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 themQ35

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. Q36

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. Q37 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 nextQ38

—–

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. Q39

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. Q40

One interesting development …

 

PART 4

Questions 31-40 dạng Gap-fill

Cách làm: 

  • B1: Đọc lướt các chỗ trống cần điền đáp án. Khoanh tròn giới hạn từ cần điền
  • B2: Đoán nhanh xem liệu loại từ cần điền vào chỗ trống là loại từ gì (danh từ, động từ, tính từ hay trạng từ) và xác định dạng từ (tên quốc gia, tên người, con số ….)
  • B3: Xác định những từ khóa trong câu chứa chỗ trống cần điền.
  • B4: Nghe và lựa chọn đáp án

A Space Traffic Management system

  • would aim to set up legal and 31 _____ ways of improving safety.

Chỗ trống cần điền là một tính từ vì nó đứng trước danh từ ways, dùng để mô tả về hệ thống giúp cải thiện sự an toàn/ngăn chặn tai nạn. Chỗ trống này không phải là từ legal do đã xuất hiện trong câu hỏi.  


=> Đáp án là technical 

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. […]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.

Problems in developing effective Space Traffic Management

  • Satellites are now quite 32 _____ and therefore more widespread

Chỗ trống cần điền là một tính từ dùng để mô tả về satellites ở hiện tại.


=> Đáp án là cheap

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. 

Problems in developing effective Space Traffic Management

  • (e.g. there are constellations made up of 33 _____ of satellites).

Chỗ trống cần điền là lượng từ , cụ thể là số lượng satellites cho các constellations, hoặc là một danh từ


=> Đáp án là thousands

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.

Problems in developing effective Space Traffic Management

  • At present, satellites are not required to transmit information to help with their 34 _____ . 

Chỗ trống cần điền là danh từ, vì đứng trước có tính từ sở hữu their. Danh từ này để nói về việc satellites không cần phải gửi lại thông tin liên quan tới cái gì.


=> Đáp án là identification 

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.

Problems in developing effective Space Traffic Management

  • There are few systems for 35 _____ satellites.

Chỗ trống cần điền là danh từ hoặc danh động từ, vì đứng sau for và đứng trước danh từ satellites. Câu hỏi nói về quá ít/thiếu hệ thống cho việc gì đối với satellites. Trong trường hợp này là theo dõi chúng.   


=> Đáp án là tracking

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.

Problems in developing effective Space Traffic Management

  • Operators may be unwilling to share details of satellites used for 36 _____ or commercial reasons.

Chỗ trống cần điền là một tính từ, được liệt kê ngang hàng với commercial, theo sau là danh từ reasons. Tính từ này dùng để mô tả mục đích của chiếc satellites, cái mà không được chia sẻ thông tin. Bên cạnh mục đích thương mại (commercial) thì chỉ có mục đích quân đội được đề cập trong bài nghe.


=> Đáp án là military

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.

Problems in developing effective Space Traffic Management

  • It may be hard to collect details of the object’s 37 _____at a given time.

Chỗ trống cần điền là một danh từ, vì đứng sau sở hữu cách the object’s, nói về một thứ khó có thể thu thập được tại một thời điểm nào đó.


=> Đáp án là location

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.

Problems in developing effective Space Traffic Management

  • Scientists can only make a 38 _____ about where the satellite will go.

Chỗ trống cần điền là một danh từ số ít vì đứng trước là mạo từ a. Danh từ này thể hiện cái mà các nhà khoa học có đưa ra liên quan tới việc satellites sẽ đi về đâu.


=> Đáp án là prediction

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.

Solutions

  • The information should be combined in one 39 _____

Chỗ trống cần điền là một danh từ số ít vì đứng trước có lượng từ one. Thông tin nên được tổng hợp trong một cái gì.  


=> Đáp án là database

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.

 

Solutions

  • A coordinated system must be designed to create 40 _____ in its users.

Chỗ trống cần điền là một danh từ, nói về việc một hệ thống phối hợp cần được thiết kế để tạo ra cái gì giữa những người dùng của hệ thống đó. 


=> Đáp án là trust

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.
