They were unmanned, although Sputnik 2 carried a dog into space.
No.
Unmanned. Explorer I, launched February 1, 1958, was the first US artificial satellite. It was approximately 4 feet long and 8 inches in diameter (1.2 m by .2 m) and weighed 30 lb. (14 kg).
Sputnik was a series of satellites built and launched by the then Soviet union. Sputnik 1 and 2 became the first two man made objects to attain orbit around the Earth.
The unique thing concerning the Sputnik 2 (compared to previous Sputnik 1 satellite) was the fact it carried the first living being into other space - a dog named Laika. "Laika" translates to English as "Barker".
The dog, Laika, died due to temperature increase.
Sputnik 2 has been in space for sixty (60) days.
The Sputnik craft were very small, unmanned satellites. But the Sputnik 2 carried a dog called Laika into space.The first man in space was Yuri Gagarin, aboard Vostok 1.

Unmanned. Explorer I, launched February 1, 1958, was the first US artificial satellite. It was approximately 4 feet long and 8 inches in diameter (1.2 m by .2 m) and weighed 30 lb. (14 kg).
Sputnik was the first artificial Earth satellite, sent into orbit by Russia. The long-retired Sputnik rocket that was used to lift off the Sputnik 1, 2, and 3 payloads was an unmanned orbital carrier rocket (8K71PS) from the R-7 family of rockets, similar to America's (also retired) Vanguard and Juno I rockets.
The Apollo 2 was unmanned. After the fire of Apollo 1, NASA felt safer testing the rocket without any crew aboard first. The next manned mission after the Apollo 1 fire was Apollo 7.
Apollo 2 was an unmanned hardware test flight. If instead you mean Apollo 11 then it was the first manned landing on the moon.
Sputnik 1 and Sputnik 2 were artificial satellites that traveled around the Earth. People thought that Sputnik 1 was spying on them, but all it did was transmit a simple tracking signal for 3 weeks.
Sputnik-2
There were a total of 19 Apollo missions: Apollo-1A : Unmanned suborbital flight Apollo - 2 : Unmanned orbital flight Apollo - 3 : Unmanned suborbital flight Apollo - 1 : Manned orbital mission, cancelled due to fatal accident. Apollo - 4 : Unmanned orbital flight Apollo - 5 : Unmanned orbital flight Apollo - 6 : Unmanned orbital fligth Apollo - 7 : Manned orbital mission Apollo - 8 : Manned lunar orbit mission Apollo - 9 : Manned orbital mission Apollo -10 : Manned lunar orbit mission Apollo- 11 : Lunar Landing mission Apollo- 12 : Lunar Landing mission Apollo- 13 : Lunar Landing mission, aborted due to accident Apollo- 14 : Lunar Landing mission Apollo- 15 : Lunar Landing mission Apollo- 16 : Lunar Landing mission Apollo- 17 : Lunar Landing mission Apollo -18 : Space rendevous mission with Soviet Soyuz spacecraft (Apollo-Soyuz)
The first man-made machine of any kind to enter space was the V-2 rocket in the 1940s. The first to orbit around the Earth was Sputnik 1 in 1957. The first manned spacecraft was Vostok 1 in 1961.
Sputnik 1 only housed some electronics, while Sputnik 2 held a dog called Laika.
The First EVER spacecraft was the unmanned Soviet Union's Luna 2. The Second and first MANNED mission was America's Apollo 11
