What happened to the Soviet spacecraft? 材料
  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 May 1969 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.”

A. It was wrecked during the mission.
B. It was recovered after its return to Earth.
