Everyday w should try and learn something new. It can be a word, phrase, trade, just whatever you learned about on a day, that you had never seen or heard of before. So here is the word I learned today ; Tardigrades also known as water bears. But why send tardigrades to the moon? Tardigrades, also known as moss piglets, are microscopic creatures measuring between 0.002 and 0.05 inches (0.05 to 1.2 millimeters) long. They have endearingly tubby bodies and eight legs tipped with tiny "hands"; but tardigrades are just as well-known for their near-indestructibility as they are for their unbearable cuteness. Tardigrades can survive conditions that would be deadly to any other form of life, weathering temperature extremes of minus 328 degrees Fahrenheit (minus 200 degrees Celsius) to more than 300 F (149 C). They also handily survive exposure to the radiation and vacuum of space.
