Can a plane go in the space?

Can a Plane Go in Space? Exploring the Possibilities

The Physics of Space Travel

Space travel has always fascinated humankind, and the question of whether a plane can go in space often arises. While planes are not built to withstand the extreme conditions of outer space, they do share some similarities with spacecraft in terms of aerodynamics and propulsion.

In order for a plane to reach and navigate in space, it would need to overcome several challenges. Firstly, it would require a propulsion system capable of providing enough thrust to overcome Earth’s gravitational pull. Additionally, the plane would need to be equipped with a life support system to sustain the crew in the airless and harsh environment of space. Lastly, it would need to have the necessary structural integrity to withstand the extreme temperatures and radiation found in space.

The Role of Propulsion

Propulsion is a key factor in space travel, whether it be by a traditional rocket or a plane. In order to escape Earth’s gravity and reach space, a vehicle must achieve a certain velocity, known as escape velocity. For Earth, this velocity is approximately 11.2 kilometers per second (6.95 miles per second). Traditional planes, with their jet engines, are not capable of generating the immense thrust required to achieve this velocity.

However, there have been conceptual designs, such as the scramjet engine, that show promise in overcoming this challenge. A scramjet engine is an air-breathing engine that relies on supersonic combustion, allowing it to reach speeds up to Mach 15. While this engine is currently being tested for atmospheric flights, it could potentially be modified for space travel.

Another possibility is the use of ion propulsion, which has been utilized in spacecraft such as NASA’s Dawn mission. Ion propulsion works by ionizing atoms of a propellant and then accelerating them using an electric field. While this method provides a low-thrust force, it is highly efficient and can be sustained for long periods of time. However, it is not yet proven if this type of propulsion can be scaled up for larger vehicles like planes.

Life Support Systems and Structural Integrity

Space is a vacuum, devoid of air and oxygen, which poses numerous challenges for human survival. In order for a plane to navigate in space, it would need to be equipped with a life support system capable of providing breathable air and removing carbon dioxide. The plane would also need to be pressurized to prevent the crew from experiencing the detrimental effects of vacuum exposure.

Additionally, the extreme temperatures and radiation in space can cause damage to the structure of a vehicle. Spacecraft are designed with special materials and shielding to protect against these hazards. A plane intended for space travel would need to have similar structural integrity to withstand the rigors of the space environment.

While it may seem unlikely for a traditional plane to go into space, advancements in technology and engineering could potentially make it a reality in the future. Scientists and engineers continue to explore new methods of propulsion, life support systems, and materials that could enable planes to venture beyond Earth’s atmosphere.

The Challenges of Atmospheric Entry and Reentry

Even if a plane were able to reach the depths of space, it would face significant challenges when reentering Earth’s atmosphere. Atmospheric entry is a critical phase of space travel that requires a vehicle to withstand extreme heat, decelerate rapidly, and maintain stability.

During reentry, a vehicle reaches speeds up to 25 times the speed of sound, resulting in intense friction with the atmosphere and extreme heating. Traditional planes, with their aerodynamic design, are not equipped to handle the high temperatures generated during this process.

Thermal Protection Systems

Spacecraft designed for atmospheric entry, such as the Space Shuttle, have unique thermal protection systems (TPS) to mitigate the effects of heat. These systems often consist of materials such as ceramic tiles or heat-resistant carbon composites. These materials are specifically engineered to withstand the extreme temperatures experienced during reentry.

In order for a plane to successfully navigate the atmospheric entry and reentry process, it would need to be equipped with a TPS capable of dissipating heat and protecting the aircraft from structural damage. The TPS would need to be lightweight yet durable, allowing the plane to maintain stability and control while experiencing intense aerodynamic forces.

Aerodynamic Challenges

During reentry, a vehicle must also contend with aerodynamic forces that can cause instability and loss of control. The shape and design of the aircraft play a crucial role in mitigating these forces and ensuring a safe descent.

Spacecraft designed for reentry often have unique shapes, such as a blunt body or a lifting body, which help to maintain stability and control during descent. These designs distribute heat evenly across the vehicle’s surface and provide the necessary lift to slow down the descent.

A plane intended for space travel would need to be aerodynamically optimized for both spaceflight and atmospheric entry. It would need to be capable of transitioning between the vacuum of space and the dense atmosphere without compromising stability and control.


While a traditional plane may not be suitable for space travel as it is, the concept of a plane going into space is not entirely far-fetched. With advancements in propulsion systems, life support technology, and structural materials, it is possible that a plane could one day venture beyond Earth’s atmosphere. However, the challenges of atmospheric entry and reentry would need to be overcome, requiring innovative solutions such as specialized thermal protection systems and aerodynamic designs. As scientists and engineers continue to push the boundaries of space exploration, the possibility of a plane in space may become a reality.
