Definition: In this task, five ordered key facts are given. All the given facts are expressed in natural language. Your job is to generate a story 100 to 1000 words long, that includes all the facts given as input in their order of appearance while expanding upon them to produce a broader, yet coherent, narrative.
Input: Fact1: astronauts In ended early late 1960s, Fact2: Russians be sending moon landing mission, Fact3: Americans had secret alternate plan to Apollo program, Fact4: American civilian be first man on moon, Fact5: Lee does not see beacon of shelter

In the late 1960s, astronauts training in an Apollo simulator have their session ended early. They grumble about it, but their commander, Chiz Robert Duvall, knows the reason for the abort: the Pilgrim Program. The Russians will be sending a moon landing mission up in four weeks. The Americans had a secret alternate plan to the Apollo program Pilgrim in case this happened. One man would be sent to the moon in a oneway rocket, a modified Project Gemini craft. He would stay on the moon for a few months in a shelter pod launched and landed before him. Later, a manned Apollo mission would come to retrieve him. The equipment is ready, but the Russians complicate matters by sending up a civilian. Chiz, although trained and qualified, is an Air Force colonel. NASA and the White House insist that an American civilian be their first man on the moon. Lee James Caan, one of Chizs crew, is tapped. Chiz is outraged, but agrees to train Lee in the few days they have. Chiz pushes Lees training hard, half to get him ready, half hoping he will drop out and Chiz can step in. Lee persists, driven by the same astronaut dream. After a press leak about Pilgrim, the Russians launch a week early. Deflated at not being first, everyone carries on. The shelter pod a LEM lander is launched and landed successfully. Lee is launched on schedule. He encounters a power drain malfunction en route which tests his character and hinders radio contact. The Russians have also lost contact with their team. As Lee orbits the moon, he does not see the beacon of the shelter. With only seconds left before he must abort and return to Earth, he lies about seeing it. Mission Control okays his retro burn and he lands. Now all radio contact is lost. Lee gets out of the Gemini lander and walks around with three hours of oxygen in his suit. He finds the crashed Russian lander on its side, the three dead cosmonauts sprawled around it. Everyone on Earth is nervously awaiting news, but none comes. Lee takes the Soviet flag from a dead cosmonaut and lays it on a nearby rock with his own American flag. With little air left and nowhere to go, Lee spins the toy mouse his son gave him. It points right, so he walks in that direction. People on Earth are losing hope as his time has run out. Lee looks at his watch to see that he has just minutes of air left. A red glow on his arm catches his attention. It is the locator beacon atop the shelter. Lee is last seen walking towards the shelter and survives.
