In the race to the moon ， who came in first ?
You might say the answer is Neil Armstrong， Buzz Aldrin ， and Michael Collins ， the crew of Apollo 11. Or you could represent for the crew of Apollo 10 ， which reached the moon in May1969 and then headed back to Earth without landing.
But there is a much stranger answer to this question ， depending on how much you care about humans and what your definition（定义） of reaching the moon might be. Before any people arrived at the moon ， other animals had got there first. And unlike the dogs and monkeys that were made famous in early space shots and Earth orbits ， the first creatures to reach the moon were a pair of tortoises ，Discovery's Amy Shira Teitel reminded us.
The Soviet spacecraft（航天器） sent the animals around the moon—although not into its orbit—during a mission in the middle of September ，1968. The unmanned（无人驾驶的） craft then returned to Earth and dashed into the Indian Ocean，after which the Russians recovered the craft.
A month later ，Soviet scientists revealed that the spacecraft had been a tiny ship ， carrying the tortoises ， wine flies ， meal worms ， plants ， seeds ， bacteria ， and other living matter.
The tortoises ， as history records ， lost about 10 percent of their body weight ， but had a healthy appetite when they returned to Earth. In the following checkups comparing the animals to stay-at-home turtles used as a test control ， "most things seemed normal ， aside from some vaguely explained minor problems with the liver.
What this all means is that ， as Teitel explained ， "The first living beings to see an Earthrise from the Moon were Russian tortoises. However，as far as I can tell ， the animals were not named.”
