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.

So yesterday, my dad checked my search history. Harmless, right? Well... you haven't seen it. Because they gave me a LONG lecture yesterday about what I read. I feel like they don't trust me on the internet anymore. But I also understand. Because you know what the history was? Phan  ѕмυт. LOTS of phan ѕмυт. How do I gain their trust? My mom won't let me use headphones and threatened to not let me go to VidCon. I'm not just angry and betrayed at my dad for snooping in my phone, but also embarrassed and ashamed. I'm only 10, for God's sake! They should be worried about my access to the internet. How do I gain their trust again?!

Funny, open-minded, a good secrets keeper, always by my side, serious when things get serious, energetic and I guess there would be more. But I don't need perfection in my friends, cause I'm not perfect either.
