Lift Off!

The first Space Transport System or Space Shuttle Orbiter was completed in 1981. A total of 5 orbiters were built. They have not been changed substantially since. Now stop and think of the technology at the time. Computers were not nearly as advanced as they are now. Consequently, operating the orbiters is a very hands-on process. In this lab, you will get a sense of just how difficult the job is by taking the role of Commander during launch.

Each orbiter has two people responsible for "flying" it: the pilot and commander. Launch is the most critical time. The number of switches and settings which must be set is enormous and they all must be done in the correct order and on schedule. Be sure to pay attention to your Mission Elapsed Time or MET clock. This will let you know when to do the next step. Additionally, you will hear your pilot tell you what to do. In a real shuttle mission you would do the same for her. The other voice you may hear is from Mission Control. They may give you instructions and be the people who will help you solve anomalies.

Your job:

Train for the launch sequence and any anomalies. Select each of the smaller steps from the drop down menu and practice until you feel you have mastered it. If you fail to stay on schedule or make repeated mistakes, you will be automatically stopped and asked to try again. Once you have the pieces mastered, attempt a nominal flight. This links all the steps together and may throw you an emergency or two. Train well now, the safety and success of the mission may rely on your skills.

During this lab you will not be working with your partner directly, but you should check with her first if you are having questions or problems. Now find a computer station. We have two setup for LiftOff: one of the PCs on the mobile table and a special iBook dedicated to this station. Ask MM if you are unsure.

When you are ready, click the LiftOff icon and make sure you have headphones.

Good luck, Commander!

Homework:

• Research the names of all 5 orbiters. Which are still in service? Why are they named they way they are?
• Take the attached list of events and put them in chronological order for the launch sequence. If you can't remember from your simulation, you may need to do a little research, but first try applying your critical thinking skills and see if you can figure it out.
• Take the practice quiz for the NASA acronyms that you should be studying.
