Hello, stargazers! In your wildest dreams, do you think it’s alright to throw things into outer space? Every single object that is sent into space remains there, including your old shoes, eaten food, and space shuttles. You must know how important it is to keep the space clean. Another alarming threat that is also familiar to many people is that of space debris.
With every other physics novel that has swamped in recent years, the article about how devas attach to bright satellites to destroy them is often present. In an exciting development, a new type of Kevlar material has been planned to be sent to the ISS in the upcoming October to conduct important research on defensive strategies for space debris. But what is this material that has never been heard before, why is it necessary and how will it protect people working in space?
Let’s dive in!
New Kevlar Material Headed to ISS in October for Space Debris Protection Tests
The Growing Threat of Space Debris
Before discussing the new Kevlar in detail, let’s consider the background of the threat of space debris. Space debris includes old satellites, used rocket stages, and debris from explosions or collisions of spacecraft. With the deployment of more satellites in orbit, the problem of space debris has only grown, endangering the very process of space exploration, crewed or uncrewed.
The European Space Agency (ESA) estimates that over 34,000 objects (larger than 10 cm in size) have remained in low Earth orbit (LEO), and millions more are smaller and pose a threat. Even a speck of dust or a pebble can prove to be extremely dangerous for a spacecraft or the astronauts on board the ISS, especially when those pieces of debris travel at a speed of 28,000 km/h (17,500 miles per hour).
The Importance of Protection Against Space Debris
Considering the current risks of space debris, the availability of appropriate protective materials has become an utmost necessity. The threats of space debris impact are perennial, as the ISS is also at risk of collision. Worse, the unfortunate event may result in the loss of the station and the crew housed inside.
In a bid to contain these threats, engineers and scientists are investigating advanced materials capable of resisting shock from oncoming projectiles. One such advancement is the new Kevlar material, which is scheduled for trials on the ISS.
Introducing the New Kevlar Material
This new type of Kevlar is an advanced engineering lightweight, high-performance fabric designed to improve its protective qualities. Most commonly associated with bulletproof vests and other forms of personal protection, Kevlar is extremely strong for its weight, which makes it an excellent candidate for space devices.
Nevertheless, this latest iteration of the Kevlar brand has been modified to enhance the fabric’s resistance to high-velocity impacts. The material is intended to absorb and dissipate energy from debris impacts more effectively, offering better shields for space vehicles and the astronauts onboard
Objectives of the ISS Tests
The purpose of the next tests on the ISS will be to investigate the behavioral characteristics of the new Kevlar in a practical environment of outer Space. The parameters of the conducted tests include:
- Impact Resistance Assessment The primary goal remains, however, to evaluate the performance of the new Kevlar material against various kinds and sizes of space debris impacts. For that scope, the engineers will research how the material behaves in terms of energy absorption and energy dissipation, given a certain impact scenario.
- Durability Testing The tests will also emphasize the evaluation of the properties of Kevlar material over time in space and aircraft structures and with respect to its exposure to space conditions such as radiation, extreme temperatures, and microgravity.
- Performance Comparison The performance of the new Kevlar material will be assessed and contrasted with the performance of the current protective materials being used in the ISS. This will show any advancement in protection and efficiency.
- Real-World Applications The results of the experiments will also suggest possibilities for developing space vehicles that integrate this new Kevlar for increased benefits on upcoming missions.
The Role of the International Space Station
Due to its extraordinary conditions, the space station serves as the best place to test new materials and technologies. The International Space Station (ISS) is also a great resource as it orbits the planet at about 400 km above sea level (248 miles) and hence experiences the same conditions that a spacecraft would. This makes it ideal for research and development.
In microgravity experiments, scientists can study mechanisms that cannot be performed on Earth. Long durations in the ISS also offer opportunities for research that significantly improves space safety and technology.
Previous Efforts in Space Debris Mitigation
The creation of shielding systems is only one science’s weapon in the fight against space debris. Many years, even decades of research and technology developments have been aimed at the problem of space debris remoteness:
- Tracking and Monitoring In order to prevent collisions with satellites and spacecraft, which can cause damage to these objects or space itself, within the space, NASA and ESA are keeping an eye on the objects and their predicted movements.
- Designing for Deorbiting A new style of satellites will enhance the chances of successful end-of-life disposal of the satellites retired from services, so users’ satellites will no longer remain stranded in high orbits.
- Active Debris Removal Different concepts are being advanced, and some of them involve active clearance of the orbital environment. These concepts involve selective capture and retrieval of non-usable satellites or space debris using nets, harpoons, or even robotic manipulators.
The Future of Space Exploration and Safety
More satellites and space actions lead to a growing necessity for a well-grounded answer to the issue of orbital debris. New materials, such as the new Kevlar, are essential for protecting space crews and ensuring the longevity of spacecraft.
Besides enhancing protective suits, such advancements may affect the structure of spacecraft to come, allowing for better survivability of the vehicles in their intended environment. Materials science will be a key contributing factor towards more ambitious outer space activities in the years to come, including missions to Mars, asteroids, and more.

Conclusion
Conducting tests of the new Kevlar fabric on board the ISS is an important milestone in the domain of advanced systems for protection from orbital debris. While we are on the verge of entering new realms of space, the security of the crew and the vessels has to be of utmost concern.
Through applied science and technological advancements in the materials used, we shall be better prepared for the adventure that is in space. The results from these tests will help to improve the safety of ongoing missions and provide a basis for future activities outside the Earth. As we await the outcome of these tests, only one question lingers: what more advanced materials and innovative technologies do we have to create to protect people as they continue into space?
