Over the past century, air travel has become more accessible thanks to advancements in airline safety and lower ticket prices. However, as airplanes continue to improve, the laws of physics limit how fast and far we can travel. But what if there was a new way to travel that could drastically cut down flight times?
Companies like Virgin Galactic and SpaceX are working to make this dream a reality by using rocket-powered vehicles for quick travel across the Earth. SpaceX plans to use its Starship rocket, initially designed for missions to Mars, to transport passengers between major cities worldwide. These flights would travel above the Earth’s atmosphere, allowing the rocket to reach much higher speeds than traditional airplanes. This could make it possible to fly to any destination on Earth in under an hour.
Flying on these rockets wouldn’t be entirely smooth. Passengers would experience g-forces during takeoff and landing, similar to a rollercoaster ride. However, for most of the journey, the rocket would coast through space, offering a zero-gravity experience. This unique environment presents challenges for designing in-flight amenities like bathrooms and food services, although the short flight durations might reduce the need for such facilities.
Virgin Galactic is also exploring the potential for Earth-to-Earth travel, but their method is quite different. Instead of a rocket, Virgin is developing a rocket-powered spaceplane that can be carried to high altitudes and launched mid-air. Both approaches could theoretically reduce flight times significantly, but before either company can start passenger flights, they must overcome several challenges.
For SpaceX, one major issue is the noise generated by their rockets, which means launches would need to occur far from urban areas, possibly over the ocean. This would require additional transportation for passengers to reach the launch sites. Virgin Galactic might face fewer regulatory hurdles since their takeoff and landing procedures are more similar to traditional air travel and could use existing airport infrastructure. They plan to build a network of spaceports worldwide, including one in southern England, which is currently under development. This spaceport would enable transatlantic test flights to and from their existing site in New Mexico.
Even if both companies secure regulatory approval, they will still face significant challenges regarding ticket pricing. For a rocket to offer ticket prices similar to those of airliners, it must be as reusable. While Virgin’s approach may seem more familiar to current air travel, it could struggle to offer reasonable ticket prices due to its smaller capacity, accommodating only six passengers and two pilots at a time, which increases the cost per ticket. Despite the higher prices, nearly 700 eager passengers are already on the waiting list for a suborbital flight aboard VSS Unity.
Before these passenger flights can become a reality, both companies must address one of the greatest challenges in spaceflight: safety. In 2017, the aviation industry recorded one death for every 60 million passengers. In contrast, the spaceflight industry has experienced one death for every 32 astronauts, with 18 fatalities among the 570 individuals who have traveled to space. Meeting safety standards remains a critical challenge for commercial spaceflight, especially following the tragic crash of Virgin’s VSS Enterprise in 2014.
While rapid travel could save significant time, it may also have physiological impacts. Traveling around the world at such speeds could disrupt our natural day/night cycles, leading to unusual effects on our bodies. Passengers might wake up to see the sunrise and then travel across the globe to witness a sunset in under an hour, potentially resulting in a more intense form of jet lag than what is typically experienced with regular airline travel.
Whether SpaceX or Virgin Galactic can realize the vision of Earth-to-Earth rocket travel remains uncertain. However, commercial space programs are making substantial progress toward achieving this revolutionary goal.
Research the current advancements in rocket-powered travel by companies like Virgin Galactic and SpaceX. Prepare a presentation that compares their technologies, goals, and challenges. Focus on how these innovations could change the future of travel. Present your findings to the class, highlighting the potential benefits and drawbacks of each approach.
Participate in a class debate on the topic: “Will commercial space travel become as common as air travel in the next 50 years?” Form teams to argue for or against the motion, using evidence from the article and additional research. Consider factors such as safety, cost, environmental impact, and technological feasibility.
Work in groups to design a safety protocol for passengers traveling on rocket-powered vehicles. Consider the physiological impacts, emergency procedures, and in-flight safety measures. Present your protocol to the class, explaining how it addresses the unique challenges of space travel.
Imagine you are part of the marketing team for either Virgin Galactic or SpaceX. Develop a marketing campaign to attract potential passengers for Earth-to-Earth rocket travel. Create promotional materials such as posters, social media posts, or a short video. Focus on the unique experiences and benefits of space tourism.
Conduct a physics experiment or simulation to understand the principles of rocket travel. Explore concepts such as g-forces, velocity, and trajectory. Use online simulations or create a simple model to demonstrate how rockets achieve high speeds and altitudes. Share your findings with the class, explaining the science behind rocket-powered travel.

Over the last century, air travel has become accessible to many due to improvements in airline safety and reduced ticket prices. However, as airplanes continue to evolve, the limitations of physics have hindered our ability to travel faster and further. But what if there was a new method of travel that could significantly reduce flight times?
Space companies like Virgin Galactic and SpaceX are working to make this a reality by utilizing their rocket-powered vehicles for rapid travel on Earth. SpaceX plans to use its Starship rocket, originally designed for Mars missions, to transport passengers to major cities around the globe. These flights would ascend above the Earth’s atmosphere, allowing the rocket to achieve much higher speeds than conventional airliners. This could enable flights to any destination on Earth in under an hour.
The experience of flying would not be entirely smooth, as passengers would encounter g-forces during launch and landing, similar to a rollercoaster ride. However, for most of the journey, the rocket would coast through space, providing a zero-gravity experience. This unique environment presents challenges for designing in-flight amenities like bathrooms and food services, although the short flight durations may lessen the demand for such facilities.
