In this article, we will delve into the challenges of managing space debris, providing a reading practice text, related questions, detailed answers, common mistakes, and useful vocabulary and grammar tips.

Challenges of Managing Space Debris

Reading Passage: Medium Text

Space Debris: An Escalating Threat to Space Activities

Space debris, also known as space junk, refers to non-functional, human-made objects in Earth’s orbit. This ever-increasing collection of defunct satellites, spent rocket stages, and fragments from collisions poses significant challenges for space missions.

Firstly, the sheer volume and speed of space debris present a formidable risk. With objects traveling at speeds exceeding 25,000 km/h, even tiny fragments can cause catastrophic damage to operational spacecraft. The biggest challenge lies in tracking and predicting the paths of these debris. Despite advancements in radar and ground-based optical telescopes, the Space Surveillance Network (SSN) can only track objects larger than 10 centimeters. Smaller debris, which are equally hazardous, remain largely untracked.

Secondly, the economic implications of managing space debris are substantial. Developing and deploying technologies to mitigate debris, such as debris removal satellites or lasers to nudge objects out of orbit, require immense financial and technological resources. The cost of shielding satellites against debris impact also drives up the expenses for space missions.

Thirdly, regulatory and international collaboration is crucial yet difficult. Space is a global commons, meaning that debris created by one nation can affect the satellites and spacecraft of another. However, establishing and enforcing international regulations on space debris mitigation has proven to be a challenge due to differing national interests and the lack of a comprehensive legal framework.

Furthermore, the phenomenon known as the Kessler Syndrome poses an escalating threat. This scenario describes a cascade effect where collisions between objects generate more debris, leading to further collisions and exponentially increasing the amount of debris in orbit. If unchecked, the Kessler Syndrome could render certain orbits unusable for decades, if not centuries.

Addressing space debris requires coordinated efforts encompassing improved tracking, innovative technologies, international regulations, and preventive measures. Collaboration among spacefaring nations and private enterprises is paramount to ensure the sustainability of space activities for future generations.

   • Explanation: The passage emphasizes that debris travels at speeds exceeding 25,000 km/h, making tracking a significant challenge.

2. b) To establish and enforce global regulations

   • Explanation: Effective management of space debris requires global cooperation to establish and enforce international regulations.

Identifying Information (True/False/Not Given)

3. False

   • Explanation: The passage explicitly states that the Space Surveillance Network can only track objects larger than 10 centimeters, leaving smaller debris largely untracked.

4. Not Given

   • Explanation: The passage mentions differing national interests and lacks a comprehensive legal framework but does not provide details about countries’ agreement levels.

5. True

   • Explanation: The passage describes the Kessler Syndrome leading to exponentially increasing debris and the potential to render certain orbits unusable for a long time.

Matching Headings

6. • Paragraph 1: i. The volume and speed of space debris

Vocabulary Highlights

1. Debris (noun)

   • Pronunciation: /dəˈbriː/
   • Definition: Scattered pieces of waste or remains.

2. Defunct (adjective)

   • Pronunciation: /dɪˈfʌŋkt/
   • Definition: No longer existing or functioning.

3. Mitigate (verb)
