Final answer:
The specific speed of the Aura spacecraft is not provided, but conversion methods between different speed units are explained using the example of Earth's escape velocity.
Step-by-step explanation:
The speed of the Aura spacecraft is not explicitly given in the provided references. However, information on how to convert speeds between different units is provided. For example, the escape velocity from Earth is 11.2 kilometers per second (km/s), which can be converted to meters per second (m/s) by multiplying the velocity in km/s by 1000, as there are 1000 meters in a kilometer. Similarly, to convert km/s to kilometers per hour (km/h), it is necessary to multiply by the number of seconds in an hour (3,600). Without specific information on the Aura spacecraft's velocity, it is impossible to ascertain its speed in any of the given units.
