Space probes are flights sent into space to collect information and pictures about the Universe. Space probes are usually sent to planets, moons, comets and asteroids. Some space probes are controlled by humans. However, most of them are unmanned and controlled directly by computers.

Space probes can be either flybys, orbiters, landers, or rovers. Flyby probes fly close to an object in space and collect data as they pass by. Orbiter probes, on the other hand, are designed to enter into orbit around an object in space and study it from a fixed location. Lander probes are designed to land on the surface of an object in space and collect data from a stationary position. Rovers, which are a type of lander, are equipped with wheels or legs to move around on the surface of an object and collect data from multiple locations.

Some examples of space probes include the Voyager 1 and 2 probes, which have explored the outer planets and are now travelling beyond the edge of our solar system, and the Mars Curiosity rover, which is currently exploring the surface of Mars.

Space Probe Journeys

A space probe may orbit a planet or a moon. They may also land on a surface to study it. They may remain there or bring data and information back to earth. Most of them send data from space by radio with the help of a process known as telemetry.

The history of space probes can be traced back to the mid-20th century, during the Cold War between the United States and the Soviet Union, which both sought to explore space and demonstrate their technological capabilities.

In 1957, the Soviet Union launched Sputnik 1, the first artificial satellite to orbit the Earth. This historic achievement inspired the United States to create its own space program, and in 1958, NASA was established.

In 1959, the Soviet Union launched Luna 1, the first spacecraft to reach the Moon and fly by it. This was followed by a series of Luna missions, which successfully achieved the first soft landing on the Moon and sent back images and data from the lunar surface.

Meanwhile, NASA launched a series of Pioneer and Ranger missions, which explored the Moon and other objects in the solar system, such as Venus and Mars.

In the 1960s and 1970s, the United States and the Soviet Union engaged in a race to explore the Moon and other planets in the solar system, known as the Space Race. The Soviet Union launched a series of Venera missions, which sent landers to Venus and returned data on its atmosphere and surface, while the United States launched a series of Mariner and Viking missions, which explored Mars.

In the decades that followed, other countries, such as Japan, China, and India, launched their own space probes to explore the solar system and beyond. Today, space probes continue to explore the universe, with missions to study asteroids, comets, and other objects in our solar system, and to search for signs of life on other planets and moons.

What Is Telemetry? 

Telemetry refers to the process of remotely measuring and transmitting data from a remote source to a monitoring station. In the context of space exploration, telemetry involves collecting data from a spacecraft or other remote device and transmitting it back to Earth for analysis.

Telemetry is used extensively in space missions to monitor the health and status of spacecraft, as well as to collect scientific data about the environments they encounter. The data collected through telemetry includes information about the spacecraft’s position, speed, temperature, power usage, and more.

Telemetry data is typically transmitted back to Earth through a variety of communication channels, such as radio waves, microwave links, or optical links. Once the data is received on Earth, it is processed and analyzed by scientists and engineers to understand the performance of the spacecraft and the scientific data it has collected.

Telemetry plays a crucial role in enabling remote exploration and scientific research in space, allowing scientists and engineers to monitor and control spacecraft from millions of kilometres away.

The First Successful Space Probe: Luna 1

Luna 1 was the first spacecraft to reach the Moon and the first human-made object to achieve escape velocity from Earth’s gravitational pull. It was launched by the Soviet Union on January 2, 1959, during the space race between the Soviet Union and the United States.

Luna 1 was a spherical spacecraft with a diameter of 0.8 meters (2.6 feet) and was equipped with scientific instruments to study the Moon’s magnetic and radiation fields, cosmic rays, and plasma in interplanetary space.

Although Luna 1 missed its intended target of a soft landing on the Moon’s surface, it successfully flew past the Moon at a distance of about 6,000 kilometres (3,700 miles) and provided valuable data about the Moon’s environment, including information about the Moon’s gravitational field and the existence of radiation belts around it.

The success of Luna 1 marked a significant achievement in the space race and paved the way for further exploration of the Moon by both the Soviet Union and the United States.

Mariner 2 was a cylindrical spacecraft, about 1.5 meters ( 5 feet ) in length and 0.5 meters ( 1.5 feet ) in diameter, and was equipped with scientific instruments to study the environment around Venus, including its atmosphere and magnetic field.

On December 14, 1962, Mariner 2 made its closest approach to Venus, flying at a distance of about 34,773 kilometres ( 21,607 miles ) from the planet’s surface. During the flyby, the spacecraft made a series of measurements that provided the first detailed information about Venus’ atmosphere, temperature, and surface.

The data returned by Mariner 2 showed that Venus’ surface was extremely hot, with temperatures around 425 °C (800 °F), and that its atmosphere was primarily composed of carbon dioxide. The spacecraft also found that Venus did not have a significant magnetic field, which was unexpected.

The success of Mariner 2 demonstrated the feasibility of interplanetary space exploration and paved the way for further missions to explore the solar system.
