Becoming an Astronaut (pg. 2)

Astronauts - The Payload Commander

A Payload Commander is responsible for the coordination of any experiments that are carried out during a space mission. For example, over 80 experiments were performed during the 16-day, STS-107 Columbia mission. One study involved the growth of prostate cancer tissue, while another showed that carpenter ants don't seem to notice weightlessness. A Payload Commander is always a NASA astronaut.

Astronauts - The Payload Specialist

A Payload Specialist is someone other than a NASA astronaut, who is assigned to a space mission by either a corporation or another country to oversee and help with a certain mission experiment. Payload Specialists can come from universities, research centers, government agencies, businesses or other nations that use the space shuttle. Usually a Payload Specialist will work on one specific experiment, but if it looks like a crew has too much work to handle on their own, the Payload Specialist will often lend a hand.

Astronauts - The Mission Specialist

There are usually three Mission Specialists aboard a space shuttle. They must have knowledge of all the experiments taking place on board, unless a Payload Specialist is in charge of the experiment and will not require help with it. A Mission Specialist also must know about safety procedures, shuttle operations, crew activity planning and the usage of consumables (food) on board the shuttle. In order to become a Mission Specialist astronaut, you have to pass a NASA Class II space physical to make sure you are in top physical condition.

Would You Like to Travel to Outer Space?

  • Yes, that would be totally wicked.
  • No way! I'm staying right here on earth.
  • Maybe if I could pass all the tests.
  • I would love to go to space... but math's not my strongest subject.

Dear Dish-It In The Forums

Hello! I'm in need of urgent advice. The guy I have a crush on and I were best friends around two years ago. Somebody told him that I like him, and now he avoids me like the plague... I really just want to be friends with him again even if he doesn't like me back. What should I do? I'm quite an awkward girl, and I can't make conversation for the life of me. We're going into seventh grade, and I haven't talked to him nor seen him all summer. Please help!

I totally feel the same way. The one guy I thought was interested friend-zoned me, so I've been kind of closed to relationships. One thing I've learned is not to jump into a relationship just because everyone else is. Just think, in 20 years they'll have all these bad memories of their many relationships, and you'll learn from their mistakes. Wanting to be in a relationship doesn't make you desperate either. You just feel a little left out. Trust me, I've been there. Don't feel alone. Being single, well, sucks, but don't worry, we've got your back, and I just know there's someone out there waiting to meet you.
