February six, 2018 was a landmark moment not only for space exploration, but also for the automotive industry. Elon Musk It was an unprecedented launch. On this day, a launch vehicle Falcon Heavy She first went on a test flight carrying an unusual cargo. Instead of a traditional concrete block or satellite, the payload was cherry red. Tesla Roadster First generation.
This car, owned by the founder personally Tesla Inc.He was wearing a mannequin in a suit named Starman. The vehicle went on a journey through an elliptical orbit that crosses the orbits of Earth and Mars. This is a non-standard approach to presentation aerospace It caused a wide resonance in the world media.
The launch was a demonstration of the capabilities of private space and the power of engines. Merlin. Observers around the world watched the broadcast, where the background of the globe slowly rotated sports electric car. This event has forever changed the way we think about how to use it. car-brand To draw attention to space achievements.
Many people wondered why they would send a car into space. The answer lies in the need to test missile systems under real, albeit symbolic, load. Tesla Roadster He was the ideal candidate, as his weight and dimensions allowed to test the stability of the flight. Falcon Heavy In near-combat conditions.
This car is now continuing its endless journey through the solar system. It serves as a unique artifact of the beginning of a new era of space exploration by private companies. In this article, we will take a closer look at the technical aspects of flight, the current location of the object, and what happens to the machine in a vacuum.
Technical details of the launch of the Falcon Heavy
Launch of a missile Falcon Heavy off-board Kennedy Space Center It was a triumph of engineering. Two-stage rocket is equipped with 27 engines Merlin It is on the first stage, which makes it one of the most powerful in the world. This is the power that allowed us to Tesla Roadster A trajectory beyond the Earth's gravity.
It is important to note that the car was not just fixed at the top. It was mounted on a special adapter, which is usually used for satellites. Inside the vehicle, a camera was installed that broadcast the image back to Earth during the first few hours of the flight. It has allowed millions of people to see it. planet From an unusual angle.
Mission control system Falcon Heavy It was supposed to provide an accurate hit in the specified corridor of the trajectory. The error in the calculations could lead to the fact that the car would remain in low-Earth orbit or would fly into interplanetary space on a completely different trajectory. Engineers SpaceX They did the job brilliantly, demonstrating high accuracy. navigational systems.
The third stage of the rocket, on which the car was mounted, performed the final acceleration impulse. After separating from the second stage, it independently entered orbit. This confirmed that the rocket is capable of delivering cargo not only to low Earth orbit, but also to higher ones, including flight paths to the Earth. Mars.
Note that it takes significantly more energy to get a cargo into orbit than it does to get into orbit, as this launch demonstrated.
Design and preparation of the Tesla Roadster for flight
The car sent into space was a serial model Tesla Roadster 2008 edition. The vehicle underwent minimal training before launch, as the primary purpose was to demonstrate, not to experiment with science. However, some systems have been modified or removed for safety and risk reduction.
There was a mannequin in the cabin. StarmanWearing a space suit designed for astronauts SpaceX. The mannequin's arms were mounted on the steering wheel, creating an iconic image of a "space trucker." The phrase was displayed on the car display. DON'T PANICIt's called "Hitchhiker's Guide to the Galaxy."
In order for the machine to withstand overload at the start, special calculations were carried out. load-holding. No one expected the car to be in space for years. The focus was on ensuring that it did not collapse or create additional debris as the atmosphere passed through.
- 🚀 The car is equipped with an engine TeslaIt is not functioning in space due to lack of air for cooling and oxidation.
- 🛡️ The body of the machine is covered with a special protective film, although it is not designed for long-term protection from radiation.
- 🎵 The car's audio system was loaded with David Bowie's album Life on Mars?, which was to be broadcast at the time of launch.
- 📡 On board is a camera with a wide-angle lens for shooting panoramas of the Earth and space.
It is worth noting that battery The car was also not designed to operate in deep vacuum and extreme temperatures. During the first hours of the flight, the car’s power system operated by transmitting telemetry and video signals, but the charge was soon exhausted.
What's in the trunk of the Roadster?
In the trunk of the car is a black box with the archive of the Human Library, containing electronic copies of Isaac Asimov’s books “Foundation”, as well as a sign with the names of SpaceX employees who participated in the project.
Current location and orbit of the vehicle
For now. Tesla Roadster It is in a heliocentric orbit, that is, it revolves around the Sun. Its trajectory is an ellipse that crosses the Earth's orbit at perihelion and Mars' orbit at aphelion. This makes the car an artificial object, periodically approaching the Red Planet.
The distance to the car is constantly changing. At the moment of maximum distance from the Earth, the distance can reach hundreds of millions of kilometers. The exact position of the object is tracked by amateur astronomers and professionals who use data on the gravitational influences of the planets.
The car doesn’t have its own propulsion system to correct its orbit, so its path is completely dependent on the gravity of the Sun and planets.
Below is a table with approximate orbit parameters. RoadsterTo help you understand the scale of your journey:
| Parameter | Meaning | Unit of measurement |
|---|---|---|
| Period of treatment | ~1.53 | year-end |
| Perihelion (min). distance | ~0.99 | ae. (Earth orbit) |
| Aphelius (max). distance | ~1.68 | ae. (behind the orbit of Mars) |
| Inclination of the orbit | ~1.04 | degree |
It is important to understand that gravitational disturbance The orbital parameters of the planets can change over time. In millions of years, the car’s trajectory could become chaotic, and it risks colliding with one of the planets or being ejected from the solar system.
Astronomers use special algorithms to predict the position of the machine. However, the error of calculations increases over time. Nevertheless, in the coming decades Tesla Roadster It will remain a predictable object in our system.
The impact of the space environment on the vehicle
Space conditions are extremely aggressive for any materials created by man. Tesla Roadster constantly exposed ultravioletIt is much more intense in orbit than on the surface of the Earth. This leads to the destruction of chemical bonds in the materials.
The first to be degraded were rubber components: tires, seals and suspension elements. Under the influence of vacuum and radiation, rubber loses elasticity, cracks and evaporates. Most likely, by now the tires of the car have completely collapsed or turned into dust.
⚠️ Warning: Plastic elements of the cabin and body paint are also eroded. Micrometeorites moving at hypersonic speeds literally "sand-blow" the surface of the machine, gradually erasing its outer layer.
The temperature in space is changing radically. On the sunny side, the temperature can rise to +120 ° C, and in the shade drop to -150 ° C and below. Such cycles thermal expansion and compressions are caused in metals and compounds, leading to the formation of microcracks.
However, some parts of the car can last much longer. Aluminum frame, glass elements and especially gold coating on some parts have high stability. StarmanA suit protected by multi-layer insulation can also partially retain its shape, although the fabric will thin over time.
- ☀️ Ultraviolet breaks down molecular bonds in polymers and dyes, changing the color and structure of materials.
- 🌡️ Extreme temperature changes cause deformation of metal structures.
- 💥 Collisions with micrometeorites create craters and gradually destroy the outer shell.
- 🛰️ The absence of an atmosphere means no oxidation in the usual sense, but atomic oxygen can be aggressive.
Interestingly, the lack of oxygen prevents the process of rusting iron in the traditional sense. However, if volatile substances remain inside the structure, they will gradually evaporate into a vacuum, changing the properties of the materials.
Legal aspects and space debris
The launch of the car into space has raised many legal questions. I agree. Convention on the registration of facilities, launched into outer space, Tesla Roadster It is registered as an object launched by the United States. The owner of the rocket and cargo is responsible for it.
The question is whether the machine is Space junk remains a controversial issue. Formally, any artificial object in orbit that does not perform useful functions can be considered garbage. However, due to its uniqueness and remoteness from the main orbital paths, Roadster It does not pose a threat to existing satellites.
☑️ Parameters of a space object
There are international standards requiring the deorbitation of spent stages and satellites after the end of a mission. In the case of Falcon Heavy and RoadsterThe object was sent to a “burial orbit” in interplanetary space, which actually solves the problem of pollution of near-Earth space.
⚠️ Warning: If the vehicle remained in low Earth orbit, it would be a source of hazard to the ISS and other satellites, requiring tracking and evasion costs.
In addition, there is the question of ownership of objects in space. Thought Elon Musk Formally owns the machine, the application of earthly laws in deep space has not yet been worked out. In the event that humanity ever decides to retrieve this artifact, a complex legal procedure will arise.
Cultural Importance and Future of Artifact
Tesla Roadster Space has become a symbol of an era when private companies have begun to play a key role in space exploration. This image of a red sports car against a blue planet has been captured in popular culture as strongly as Carl Sagan’s Pale Blue Dot.
For engineers and enthusiasts, this facility serves as a reminder that technology is a powerful tool for the future. electric motor And rocketry can go hand in hand. The car proved that an electric car can be not just a means of transportation on the ground, but also part of space expansion.
In the future, when humanity will begin to actively explore Mars, this car may become a historical landmark. Imagine an expedition that hundreds of years from now will meet this rare thing drifting near the orbit of Mars. It will be a direct link to the beginning. new space race.
Bye. Roadster continues its quiet flight. It doesn’t make sounds, doesn’t require fuel, and doesn’t age in human terms. It is a monument to the ambitions of humanity of the beginning of the XXI century, frozen in time and space.
How long will the car fly by?
According to astronomers, the car could exist in orbit for billions of years until it collides with the planet or is ejected from the solar system by gravitational maneuver.
