List of spacecraft called Sputnik facts for kids
Sputnik (Спутник) is a Russian word that means "satellite" or "traveling companion." It's famous because it was the name of the very first spacecraft launched by the Soviet space program. These spacecraft were a big step in space exploration!

The First Official Sputniks
The Soviet Union officially named three main spacecraft "Sputnik." These were groundbreaking missions that changed how we saw space.
Sputnik 1: The First Satellite
Sputnik 1 was launched on October 4, 1957. It was the first artificial satellite ever to orbit Earth! This small, shiny ball sent out radio signals that people all over the world could hear. It showed that humans could send objects into space.
Sputnik 2: Laika's Journey
Just a month later, on November 3, 1957, Sputnik 2 was launched. This spacecraft made history for another reason: it carried the first living animal into orbit, a dog named Laika. Her journey helped scientists learn how living things might survive in space.
Sputnik 3: A Science Lab in Space
Sputnik 3 was launched on May 15, 1958. This satellite was much bigger and carried many scientific tools. It was designed to study Earth's upper atmosphere and the space around our planet. It gathered important information for future space missions.
Other Spacecraft with "Sputnik" in Their Names
Because "Sputnik" simply means "satellite" in Russian, the word appeared in the names of other Soviet spacecraft too. These were not part of the original "Sputnik" series but were still important.
Dnepropetrovsk Sputniks
The Dnepropetrovsk Sputnik series included satellites used for scientific research and to test new technologies. They helped develop better spacecraft for the future.
Istrebitel Sputnikov: Satellite Destroyers
The Istrebitel Sputnikov series translates to "Destroyer of Satellites." These were experimental spacecraft designed to test anti-satellite weapons. They were part of military space programs.
Tyazhely Sputnik: Heavy Satellite
Tyazhely Sputnik means "Heavy Satellite." This was a spacecraft that was supposed to go to Venus, but it didn't make it into space successfully.
Upravlyaemy Sputnik: Controllable Satellites
The Upravlyaemy Sputnik series means "Controllable Satellite." These satellites were used for important tasks like watching the oceans and detecting missiles. Some examples include:
- US-A: These satellites used nuclear power to watch the oceans with radar.
- US-K: These satellites helped detect missiles from a special orbit called a molniya orbit.
- US-KS and US-KMO: These were advanced satellites in a geosynchronous orbit, meaning they stayed over the same spot on Earth, also used for missile detection.
- US-P and US-PM: These satellites were used to watch the oceans using electronic signals.
Spacecraft Called "Sputnik" by Others
Sometimes, people in other countries called certain Soviet spacecraft "Sputnik" even if that wasn't their official name. This often happened when the real Soviet name wasn't known right away. Here are a few examples of what they were officially called:
- Sputnik 4 was actually Korabl-Sputnik 1.
- Sputnik 5 was Korabl-Sputnik 2.
- Sputnik 7 was Tyazhely Sputnik.
- Sputnik 8 was Venera 1, a probe heading for Venus.
- Sputnik 10 was Korabl-Sputnik 5.
- Sputnik 23 was Mars 1, a probe heading for Mars.
Sputniks Named After Sputnik 1
Later, some small satellites were named "Sputnik" to honor the first one. These included Sputnik 40, Sputnik 41, and Sputnik 99.
