"Geoffrey A. Landis - Mars Crossing" - читать интересную книгу автора (Landis Geoffrey A)Mars tugs at the human imagination like no other planet. With a force mightier than gravity, it attracts the eye to its shimmering red presence in the clear night sky. It is like a glowing ember in a field of ethereal lights, projecting energy and promise.

At one end of the spacecraft was the habitat, a squat, rounded cylinder sitting on a heat shield. It was separated from the main rocket engine and now-empty fuel tanks by two kilometers of tightly stretched rope, a super-fiber tether so thin as to be nearly invisible. The spacecraft and the fuel tanks slowly rotated around the center of the tether. "Arm tether separation." "Tether separation armed." "Navigation?" "System status?" "Systems are go."

"PD preheat on." "Fire pyros for tether sep on my mark. Three, two, one, now." The spacecraft jerked, and the tether, suddenly cut free, recoiled away from the spacecraft, writhing and twisting like an angry snake. The engines, solar arrays, and fuel tanks sailed slowly off into the distance. They would miss Mars and sail outbound on an endless trajectory into interplanetary space. "Tether separation confirmed. We're committed." "How's the trajectory?" "We're on the numbers. Looking good." "Instrument check." "Instruments green." "Everything green. We're sliding right down the groove." "Then buckle up, everybody. We're going in." The spacecraft burned through the Martian atmosphere, leaving a trail of fire across a pink sky.
