The Cygnus OA-7 Mission was launched on April 18, 2017 to the International Space Station (ISS) to deliver supplies. The ISS is at a 409 altitude circular orbit. The resupply spacecraft performed the following mission (not exactly but good for this problem):
- launched into a 210 by 298 km altitude elliptical orbit and completed 1 orbit.
- performed a Hohmann transfer from the apoapsis of the insertion orbit to the 409 km altitude ISS orbit
- circularized at the 409 km altitude
- μ of Earth is 398600 km3/sec2 and radius of Earth is 6378.0 km.
Compute the periapsis and apoapsis velocities of the Hohmann transfer orbit.
a. Vp = sqrt(mu*(2/rp -1/a)) 7.631887529 km/sec
Va = sqrt{mu*(2/ra-1/a)} 7.758780805 km/sec
b. Vp = sqrt{mu*(2/rp-1/a)} 7.758780805 km/sec
Va = sqrt(mu*(2/ra -1/a)] 7.631887529 km/sec
c. Vp = sqrt(mu*(2/rp -1/a)) 7.893317539 km/sec
Va = sqrt{mu*(2/ra-1/a)} 7.958780805 km/sec
d. Vp = sqrt(mu*(2/rp -1/a)) 7.331487529 km/sec
Va = sqrt{mu*(2/ra-1/a)} 7.158780805 km/sec

Use the information below to answer parts a–b. The International
Space Station (ISS) orbits the Earth at an altitude (distance above
the surface of the Earth) of 408 km, conducting various experiments
in a “weightless” environment.
a) Recall: the centripetal force is equal to the net inward
force on an object. Consider the other force(s) acting on the ISS
and write an equation relating its force(s). Air resistance is
negligible.
b) Determine the speed that a rocket carrying supplies for...

Two astronauts are on a space station preparing for a mission to
Mars. The space station is powered by the combustion of a mixture
of gases released from the high pressure container in which they
are both contained. When not in use, the high pressure gas canister
is stored in the far corner of the station away from the crew. One
of the two gases possesses a high molecular weight, has a strong
foul odor but is harmless to humans...

An astronaut has left the International Space Station to test a
new space scooter. Her partner measures the following velocity
changes, each taking place in a time interval 10.9 s . What are the
average acceleration in each interval? Assume that the positive
direction is to the right.
Part A
At the beginning of the interval the astronaut is moving toward
the right along the x-axis at 14.1 m/s , and at the end of
the interval she is moving...

An astronaut is floating inside the international space station
at rest--and since there are no other external forces she can rely
on to change her state of motion--she decides to throw her jacket
across the room. If her mass is 66.9kg and she throws the 1.1kg
jacket at 14.7 m/s -- what is her recoil speed?

The International Space Station uses the electrolysis of water
to continuously replenish the oxygen in the station’s atmosphere
(the hydrogen formed is vented). The station’s electricity is
generated by the four arrays of solar modules, which produce a
total of 120 kW. Essential heating/cooling, circulation and
steering equipment requires 75 kW. If one of the four modules fails
completely, this leaves 15 kW for O2 production, which is run at a
2 V potential. How many astronomers can survive on...

On Jan. 28, 1986, the space shuttle Challenger launched
for its tenth and final mission. Seventy-three seconds into launch,
the Challenger exploded with seven astronauts aboard,
including Christa McAuliffe who had been selected to be the first
teacher in space.
After a lengthy investigation, NASA concluded that the shuttle
was destroyed when a primary and secondary O-ring on a solid rocket
booster failed to seal and seat properly. The seal design was
faulty, and the problem was made worse by...

A rocket ship is launched from rest from a space station. Its
destinations 1.0 x 10^11 m away. The ship is programmed to
accelerate at 7.4 m/s^2 for 12 hours. After 12 hours, the ship will
travel at constant velocity until it comes within 1.0 x 10^10 m of
its destination. Then, it will fire its retrorockets to land
safely.
