Air-Launch Systems: A New Perspective on Reaching Orbit
Virgin Orbit's LauncherOne system offers a unique approach to reaching orbit, one that provides several advantages over traditional ground-based launches:
Flexibility in launch locations: By using a modified Boeing 747 as a mobile launch platform, Virgin Orbit can theoretically launch from any airport with a long enough runway. This opens up new possibilities for launching from locations closer to the equator or optimized for specific orbital inclinations.
Reduced weather dependencies: Air-launch systems can fly above much of the lower atmosphere, reducing the impact of weather on launch windows.
Lower infrastructure costs: Without the need for expensive ground-based launch facilities, air-launch systems can potentially offer more cost-effective access to space.
Improved payload efficiency: Launching from high altitude means the rocket doesn't need to fight through the densest part of the atmosphere, potentially allowing for more efficient use of fuel.
The LauncherOne system works by carrying a two-stage rocket to an altitude of about 35,000 feet. The rocket is then released, ignites its engine mid-air, and continues its journey to orbit. This method has been successfully demonstrated, with Virgin Orbit achieving its first commercial payload delivery in January 2021.
While air-launch systems offer unique advantages, they also come with their own set of challenges. The size of payloads is limited by the carrying capacity of the aircraft, and the complexity of mid-air launches introduces new potential points of failure. Despite these challenges, the flexibility and potential cost savings of air-launch systems make them an attractive option for certain types of missions, particularly in the small satellite market.
Reusability: Not Just for the Big Players
SpaceX may have popularized the concept of reusable rockets with their Falcon 9 boosters, but small companies are adapting this approach to their scale:
Rocket Lab's Electron rocket: Rocket Lab has announced plans to recover and reuse the first stage of their Electron rocket. Their approach involves using parachutes to slow the booster's descent, followed by mid-air capture by helicopter. This method is particularly suited to smaller rockets, where the fuel required for a propulsive landing (as used by SpaceX) would significantly reduce payload capacity.
Partial reusability: Some companies are exploring partial reusability, focusing on recovering the most expensive components of the rocket rather than the entire first stage. This approach can offer some of the cost benefits of reusability without the full complexity of landing an entire rocket stage.
Rapid refurbishment: Even when full reusability isn't feasible, companies are focusing on designing rockets that can be quickly refurbished and relaunched. This approach can significantly increase launch frequency and reduce costs.
The push for reusability in the small rocket sector faces unique challenges. The smaller size of these rockets means there's less margin for the additional systems required for recovery and reuse. However, the potential cost savings and increased launch frequency make it an attractive goal.
These advancements in reusability are making space more accessible than ever before, potentially opening up new markets and use cases for space technology.
