31. However, the third stage solid motor ruptured, de-orbiting the satellite almost immediately after orbital insertion while achieving orbital velocity . 32. If the orbital velocity and the tether rotation rate are synchronized, the tether tip moves in a cycloid curve. 33. After shutting the inlet cone off at Skylon to reach orbital velocity after leaving the atmosphere on a steep climb. 34. Maximum efficiency of inclination change is achieved at apoapsis, ( or apogee ), where orbital velocity v \, is the lowest. 35. :: : : Well orbital velocity depends on the relevant masses of the bodies as well as the distance between them. 36. MY Cam is a contact binary and eclipsing binary, with an orbital period of 1.2 days, and an orbital velocity of. 37. The solar wind must push the planets out a bit further than their natural orbits ( based on their orbital velocities ). 38. The circular orbit of minimum radius " r " s } } corresponds to an orbital velocity approaching the speed of light. 39. This is easily achieved on the Moon due to lower orbital velocity , lower lunar gravity and the absence of any significant atmosphere. 40. It only needs to lose about 1 % of its orbital velocity in a typical reentry burn; the atmosphere does the rest.
