Final answer:
The instruments that could be included on a spacecraft to match course with a comet and gather data are a compass, altimeter, airspeed indicator, and IMU equipment.
Step-by-step explanation:
When designing a spacecraft to match course with a comet, there are several instruments that could be included to gather data. Some of these instruments include:
- Compass: This instrument can provide information about the direction and orientation of the spacecraft relative to the comet.
- Altimeter: An altimeter can measure the altitude of the spacecraft above the comet's surface.
- Airspeed indicator: This instrument can be used to measure the velocity of the spacecraft with respect to the comet and determine its airspeed.
- IMU (Inertial Measurement Unit) equipment: An IMU can provide information about the spacecraft's acceleration and orientation in space.
By using these instruments, valuable data about the comet's environment, such as its magnetic field, atmospheric conditions, and gravitational forces, can be collected.
