History of Reusable Rockets
Reusable rockets have revolutionized the space industry by making space travel more accessible and cost-effective. The inception of reusable rockets dates back to the early 1980s when NASA attempted to reduce the cost of space shuttle launches by developing a reusable spacecraft. The Space Shuttle program intended to launch and land a spacecraft like an airplane to enable closer examination and more frequent updates of satellites, among many other objectives.
However, the space shuttle turned out to be far from reusable. Although NASA initially viewed the shuttles as fully reusable, they quickly realized that the costs to refurbish and launch each shuttle outweighed the benefits of creating a system that would take relatively frequent shuttle launches.
Types of Reusable Rockets
- Partial Reusable Rockets
- Fully Reusable Rockets
- Semi Reusable Rockets
- Heat Resistance: One of the biggest challenges in developing reusable rockets is ensuring they can withstand the extreme temperatures and pressures of reentry. The intense heat generated during the descent can easily damage even the most durable materials, which makes it crucial to design structures and materials that can withstand the heat.
- Costs: Developing reusable rockets is extremely expensive, with some experts estimating that a single reusable rocket could cost up to ten times more than a regular rocket. The high costs are largely due to the fact that reusable rockets require more advanced technologies and a more complex design, which considerably increases the manufacturing processes and the quantity of fuel needed.
- Safety: Safety is always a top priority when it comes to rocket launches. Developing reusable rockets means creating a complex system that is both safe to launch and also safe for re-entry. The risks of explosions or crashes during re-entry are very high if the technological features that enhance the safety of reusable rockets are not taken into account and this may result in a catastrophic event.
- Advanced Materials: Engineers are exploring the use of advanced materials, including lightweight and heat-resistant composites to create reusable rockets. These materials are stronger and have a better heat resistance, which can significantly increase the rocket’s durability.
- Advanced Propulsion Systems: Advanced propulsion systems, such as electric propulsion or plasma rocket engines, can reduce or eliminate the need for fuel and enhance the rocket’s maneuverability. These systems could help increase the efficiency of reusable rockets and reduce their overall operating costs.
- Autonomous Landing: One of the major advantages of reusable rockets is that they can land themselves. Engineers have been investing in advanced control systems that enable rockets to safely touchdown with pinpoint accuracy, even in challenging weather conditions, thus reducing the risk of accidents during landing.
- Cost Savings: Launching a single-use rocket means losing millions of dollars in discarded equipment. By making rockets reusable, SpaceX hopes to bring down the costs of launches and make space travel more affordable for everyone.
- Reducing Environmental Impact: By reusing rockets, SpaceX can reduce the amount of debris that is left in space after a launch. This means that the environment will be less impacted by discarded debris from rockets.
- Opening Up New Frontiers: The SpaceX reusable rocket technology will make it possible to launch rockets more frequently and with less expense. This could lead to other space projects and expeditions that were once deemed too expensive or impractical, making space travel more accessible and opening up new frontiers for exploration.
- The Vulcan Centaur will be able to launch up to 29,000 kg of payload into low Earth orbit.
- The reusable first stage will be able to land vertically, similar to SpaceX’s Falcon 9 rocket.
- ULA plans to use the BE-4 engine, which is being developed by Blue Origin, for both the Vulcan Centaur and other rockets.
- Lower Cost of Space Missions: The most obvious economic impact of reusable rockets is the reduction in the cost of space missions. By reusing rockets, the cost of manufacturing, testing, and launching a rocket is spread out over multiple launches, drastically reducing the overall cost. SpaceX, for example, has estimated that reusing a Falcon 9 rocket can save up to 30% of the cost of a new rocket.
- Increased Access to Space: With the lower cost of space missions, smaller companies and organizations can now afford to launch payloads into space. This increased accessibility has led to a surge in innovation, with companies leveraging this technology to create new services and applications that were not possible before.
- Job Creation: The development of reusable rocket technology has also created new jobs in the space industry, particularly in manufacturing, maintenance, and operations. As more companies adopt this technology, there will be increased demand for skilled workers to support these endeavors.
A partial reusable rocket, as the name suggests, only has specific components that can be used more than once. For instance, the first stage of the Falcon 9 rocket can return to Earth, undergo inspection, refurbishment, and refuel for a subsequent launch. In contrast, the second stage only has a single-use engine, making it a fully expendable component.
On the other hand, fully reusable rockets are designed to be used multiple times without always replacing any parts. Such rockets fall into two categories: crewed and uncrewed. Crewed fully reusable rockets, as their name suggests, are capable of carrying astronauts and are considered much safer than one-use rockets. An example is the SpaceX Crew Dragon rocket. Uncrewed rockets do not carry people but can carry satellites and other cargo. One of the most popular examples of fully reusable rockets in the uncrewed category is the Falcon 9 rocket.
Finally, semi-reusable rockets have parts that can be used more than once, but not the entire rocket. One popular example is the Soviet (later Russian) R-7 booster.
Advantages of Reusable Rockets
Reusable rockets offer several advantages over non-reusable ones. Firstly, it reduces the cost of space travel as space agencies no longer need to spend massive amounts of money on creating new rockets for each launch. Additionally, reusable rockets can be launched more frequently, enabling faster and better research outcomes. They also reduce the amount of waste generated by space travel and increase public interest in space exploration due to cheaper costs and frequent launches.
Conclusion
In summary, the history of reusable rockets dates back several decades, with the first initiative by NASA to reduce the cost of space shuttle launches.
