|This is not a pipe. (It is a picture of a pipe)|
|Is this a picture of a spacecraft?|
- It has structure.
- It has command/data handling.
- It has a science payload with multiple instruments.
- It has independent power - it is charged from the rocket payload, but carries its own battery and is capable of operating for the whole mission from launch through recovery. In fact, it did operate on its own power during entry and descent. From the point of view of the Rocketometer, the external power system is ground support equipment.
- It is capable of operating in the vacuum and freefall of space. If it were magically transported into orbit, it would operate for at least a little while (it lacks thermal control).
- It lacks propulsion and recover, but so do many spacecraft.
The biggest strike against it is that it was bolted inside another spacecraft. How many other systems in the rocket would I count as a spacecraft under this same definition?
