English: Hello, my name is Diana Alicea and I work for NASA at Kennedy Space Center, Florida with the Launch Services Program. In the rocket business, I am an Electrical Engineer working as an Instrumentation engineer. This might sound complicated but it's really fun. What is instrumentation? Instrumentation is a way of gathering the health of a rocket while it is flying. In other words, instrumentation consists of sensors that measure things like pressure, temperature, and acceleration. These instruments tell us when the engine starts, what is the power consumed by the rocket, what temperatures the rocket is experiencing and how fast it's going. There are hundreds of instruments in and on the rocket that help us determine if the rocket is performing as planned and if it is headed in the right direction. They are our eyes and ears since there are no astronauts on Expendable Launch Vehicles. All the information that we receive is beamed to the ground in radio waves that we call telemetry. Someti
