Korean & Spanish Rocket Scientists: A Happy Lot


Last week’s on-target Ariane 5 launch occurred at sunset in French Guiana, providing an excellent view of the vehicle’s ascent – including the separation of its two solid boosters at an altitude of some 67 km., and the payload fairing’s jettisoning at 106 km.    Estimated orbital parameters at the injection of its cryogenic upper stage:
– Perigee: 249.4 km. for a target of 249.4 km.
– Apogee: 35,922 km. for a target of 35,907 km.
– Inclination:  2.99 deg. for a target of 3.00 deg.
