Problem 1: Consider a spacecraft in an elliptical orbit. In its perigee at 2,000 km altitude above sea level, it has a speed of 9 km/s. If its speed at apogee is reduced to 6 km/s, what is the corresponding altitude above sea level? Note: altitude above sea level ‡ orbital radius! Problem 2: What is the orbital period of the spacecraft in the aforementioned orbit?

Show that for eccentricity equal to one in Equation 13.10 for conic sections, the path is a parabola. Do this by substituting Cartersian coordinates, x and y, for the polar coordinates, r and , and showing that it has the general form for a parabola, x=ay2+by+c .
Let's assume that the Earth is orbiting around something with the 1/100th mass of our Sun (the mass of Earth is still relatively negligible for our purposes). If the orbital distance of the Earth were to remain constant at 1 AU, what must the new orbital period of the Earth be in years?
AVHRR/3 is a multispectral sensor onboard NOAA-15, a sun- synchronous platform that has an orbital period of 102.12 min. It has a swath width of 2900 km. How many AVHRR/3 orbits are produced per day? Do 2 consecutive orbits overlap at the equator? Explain your answer. (Hint: Assume Earth’s circumference at the equator = 40000 km)
A satellite orbits the Earth in an elliptic orbit with eccentricity 0,3. Itspericentric height is 150 km. What is its velocity at a height of 300 km?If its speed at perigee is decreased by 10%, still perpendicular to theradius, determine if if it will stay in an orbit or hit the Earth.
A satellite in orbit around the earth is at an altitude of 107 percent of the earth's radius. Rounding off our old friend "g" to ten meters per second squared, what is the acceleration due to earth's gravity at the satellite? Your answer should be in meters per second squared, but do not put the unit, just the number.
As you pilot your spacecraft in a circular orbit about the Earth, you notice the space station you want to dock with severalmiles ahead in the same orbit. To catch up with the space station, should you fire your accelerating rockets or fire your decelerating rockets?
Please don't provide handwritten solution ..... Given an elliptical orbit with a perigee of 6500 km and a 60,000 km apogee, find the true anomaly of the spacecraft position when it enters the Van Allen belt at an altitude of 500 km (consider only gravitational forces).
Show that the areal velocity for a circular orbit of radius r about a mass M is ΔA/Δt =1/2 √GMr . Does your expression give the correct value for Earth’s areal velocity about the Sun?
Engineers and science fiction writers have proposed designing space stations in the shape of a rotating wheel or ring, which would allow astronauts to experience a sort of artificial gravity when walking along the inner wall of the station's outer rim. Imagine one such station with a diameter of 126 m, where the apparent gravity is 3.90 m/s2 at the outer rim. How fast is the station rotating in revolutions per minute? What If? How fast would the space station have to rotate, in revolutions per minute, for the artificial gravity that is produced to equal that at the surface of the Earth, 9.80 m/s2?
Haley’s Comet closest approach to the Sun is within 0.570 A.U., and its orbital period is75.6 years.Problem 4.1. What is the semi-major axis of the comet’s orbit?Problem 4.2. How far from the sun will Haley’s comet travel before it starts its returnjourney?
While standing on the surface of a spherical asteriod of mass M and radius R., and astronaut thows a small rock straight upward away from the center. What is the minimum speed she must give to the rock to reach a height h above the surface. Assume that h is not small compared to R. The asteriod has no atmosphere and take the rock's mass to be small compared to M.
When a falling meteoroid is at a distance above the Earth's surface of 3.30 times the Earth's radius, what is its acceleration (m/s2 towards earth) due to the Earth's gravitation?
