- It was stated that a satellite with negative total energy is in a bound orbit, whereas one with zero or positive total energy is in an unbounded orbit. Why zero or positive total energy is in an unbounded orbit. Why is this true? What choice for gravitational potential energy was made such that this is true?arrow_forwardSince 1995, hundreds of extrasolar planets have been discovered. There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star. The semimajor axis of an extrasolar planet is inferred from its period. What range in periods corresponds to the habitable zone for an Earth-like Planet orbiting a Sun-like star?arrow_forwardA spacecraft with a mass of 5000kg is in circular orbit 2000km above the surface of mars. How much work must the spacecraft engines perform to move the spacecraft to a circular orbit that is 4000km above the surface? (hint Total Energy = Ep+ Ek)arrow_forward

How much energy is required to accomplish this?

A transfer stage is a rocket specifically designed to move (or transfer) satellites from LEO to GEO. Compare the amount of energy it requires to transfer a 8,000 kg satellite from a 750 km altitude orbit to GEO with the amount of energy required to send a 8,000 kg spacecraft from the same LEO orbit to the Moon so that it can land on the surface of the Moon. Note that the Lunar spacecraft will need the same orbital speed as that of the Moon around the Earth so that the Moon doesn’t move away from the spacecraft before it has a chance to land.arrow_forward
