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.

Talk to your parents about it. Tell them you didn't like your Christmas gift, and don't let your brother boss you around. Your parents can, your brother can't. Your parents gave you life, sorry to tell you but they can do anything they want if it's legal. But your brother can't. Let your parents know that you shouldn't have gotten in trouble for the stuff he doesn't. Tell them he makes you feel really awful and you don't like it. If they're good people they'll understand.

I would stop being friends with her. I mean she should understand that it'd be mean to do that. It's hard to help your friend get through a breakup when you're dating the same person. Plus you don't even know if she was trying to break you guys up so she could be with him.

You want to know if he likes you or not? Just ask him. It's not as bad as people say-I mean, it's a question. It looks like he does, so he probably does. It's not that big of a deal.

Talk to your friend. Tell her that this is the first guy that's ever liked you but you don't want her to get mad at you for stealing him from her. But understand she likes him too so don't get mad if she doesn't want you dating him. Nicely decide which of you should get him instead of the other. Chances are she might be thinking the same thing.
