A)
The mass of Mars is about 1/10 the mass of Earth. Its diameter is about 1/2 the diameter of Earth. What is the gravitational acceleration at the surface of Mars?
9.8 m/s2
2.0 m/s2
3.9 m/s2
4.9 m/s2
none of these
B)
A 9.0 x 10 3 kg satellite orbits the Earth at the distance of 2.56 x 10 7 m from Earth’s surface. What is its period?
1.1 x 10 4 s
4.1 x 10 4 s
5.7 x 10 4 s
1.5 x 10 5 s
Delay time for communication between GEO satellites and Earth.
Use the relationship between distance (d), time (t) and speed (v),
d = vt
to repeat the calculation we did in class, but this time using the English units. Use the fact that
GEO satellites orbit at 22,236 miles above Earth's equator, and that the speed of light is
1.86 x 105 mi/s. (Note that both of these values are equivalent to those used in class.) You
may want to write this calculation on paper and insert a photo here.

- Question 1 (Total: 30 points) a. What is a repeat ground-track orbit? b. Explain why repeat ground-track and Sun-synchronous orbits are typically used for Earth observation missions. c. The constraint for a Sun-synchronous and repeat ground-track orbit is given by T = 286, 400, where I is the orbital period in seconds, m the number of days and k the number of revolutions. Explain why this is, in fact, a constraint on the semi-major axis of the orbit.arrow_forwardAs discussed in class, the moon is receding from the Earth due to tides at a rate of ~4 cm/year. Let’s assume that rate has been constant throughout time (it wasn’t, but we can use it to illustrate some key points). Its current semi-major axis is 384,400 km.a) If the moon formed 4.5 billion years ago and has been receding from the Earth ever since, what was its original semi-major axis? What was its original orbital period?b) What would the apparent size of the Moon have been in the sky as viewed from Earth? That is, in Hmwk 2, you were told the diameter of the Moon spans about 0.5o when viewed from Earth today. What would it have been when the Moon first formed?
