- 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

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...

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.

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.
