Space Rocket History

Both men realized what they had discovered. The rock was almost entirely plagioclase. This was surely a chunk of anorthosite, a piece of the primordial crust, the Genesis Rock.

Suddenly, Scott called out that the Rover was beginning to slide down the hill.  As the back wheels came off the ground, Scott quickly got back on to hold the rover down.

The whole stripped-down rover weighed about 455 pounds on Earth but only 76 pounds on the moon and was built to carry 2 1/2 times its weight at a maximum speed of about 10 miles per hour.

After a good nights sleep, Houston woke the astronauts up an hour early the next morning because of a slight oxygen leak.

It was immediately clear that Falcon had landed on uneven ground, right on the rim of a small crater; the LM was tipped backward at a slight angle. It turned out that one of the rear feet had landed in … Continue reading →

Craning to look through the triangular window for a glimpse of the land ahead, Scott saw no sign of Hadley Rille.

The SPS engine was used for all the future burns.   It was the astronauts ticket home.  Any doubt as to whether it could fire raised the question as to whether the mission could continue.

For Scott all feelings were forgotten. All senses except sight were subordinated. All Scott’s concentration was focused on hearing information from Irwin, Worden and Mission Control about the status of the spacecraft and the Saturn V.

The last face they saw was Guenter’s, smiling and waving an enormous crescent wrench. Then the heavy hatch closed with a deep thunk.

As Command Module Pilot for Apollo 9, Scott’s responsibilities were heavy. The Lunar Module was to separate from the Command and Service Module during the mission; if it failed to return, Scott would have to run the entire spacecraft for … Continue rea...

Dave Scott showed incredible presence of mind during the unexpected events of the Gemini 8 mission. Even in the middle of an emergency, out of contact with Mission Control, he had thought to reenable ground control of the Agena before … Continue reading →

The twelve day Apollo 15 mission was scheduled to launch on July 26, 1971.  It would be the fourth United States human exploration of the Moon. As compared with earlier missions, Apollo 15 would double the time and extend by … Continue reading →

It was decided that henceforth, cosmonauts would wear pressure suits for launch and the return to Earth. Also, a system was installed to automatically pump air into the descent module in the event of decompression.  Additionally,

The recovery team quickly opened the hatch and were shocked to find the men motionless, as if asleep or unconscious.

Volkov transmitted to Flight Control: “The hatch is not hermetically sealed! … What can we do? … What can we do?”

Just before the start of another communication session, Volkov noticed a smell of smoke from somewhere at the rear of the station. As soon as communication with the ground was established, he reported:  “Aboard the station is ‘the curtain’!”

Dobrovolsky wrote in his diary, “Some days were a nightmare. There was a general absence of everything: no interesting things, no happiness, the monotonous sound of the ventilators, strong smells, numerous experiments.

Volkov radioed “Zarya, wait! Yantar 3 is in Soyuz. Don’t start until Yantar 3 has returned to the Salyut! There is a strong smell in Salyut! He will put on a mask and go in again!”

“I am proud to have been involved in the Vostok spacecraft which carried Gagarin on the first manned space flight and in its modification for Voskhod.” Volkov

Dobrovolsky was blond, tall, broad-shouldered, and tough. He was kind-hearted and had a contagious belly laugh. At the Air Force school, his friends nicknamed him `Odessa’, and he was proud of it. 

On May 4th, 1971 the prime crew of Soyuz 11 was confirmed to be Leonov, Commander; Kubusov, Flight Engineer; and Kolodin, Research Engineer. Their assignment was to spend between 30 and 45 days on board Salyut 1.

… There was no provision for the possibility of undocking if the entire docking cycle had not been executed …

“They can’t approach at that rate,” fretted Mishin. “Why aren’t you doing anything? Tell the crew what to do!” “We don’t need to do anything; deceleration will begin now,” Rauschenbach reassured Mishin.

The objective of the Soyuz 10 mission was to deliver and return to earth the first crew of Salyut 1.  The Soyuz was to hard dock with Salyut 1 and then the crew was to transfer internally to the station. … Continue reading →

In record time, the OKB-1 rebels led by Yuri Semenov developed the space station designated DOS-7K. The station used the body of a vehicle from the Almaz project, but outfitted it with modified systems from the Soyuz spacecraft.

“For one priceless moment, in the whole history of man, all the people on this earth are truly one. One in their pride in what you have done. And one in our prayers that you will return safely to earth” … Continue reading →

Alan Shepard’s wife Louise was elated after watching on TV as Shepard boarded a Navy ship bound for Houston, where he would be safe behind the glass windows of the post-flight quarantine room.

Gradually, as Mitchell worked and glanced at the bright crescent, he was filled with a quiet euphoria, great tranquillity, and an overpowering sense of understanding. It was as if he had suddenly begun to hear a new language,

Would the docking probe that caused so much difficulty a week ago during the first docking work now or would Shepard and Mitchell be forced into a space walk in Lunar orbit?

141:45:30 Shepard: Okay. The abort stage is set. Ascent Engine is Armed. 6, 5, 4… 141:45:38 Mitchell: Proceed with the ignition program 141:45:38 Shepard: …3, 2, 1, 0… 141:45:42 Mitchell: Ignition. 141:45:43 Shepard: We have ignition… 141:45:44 Mitchel...

“It was terribly, terribly frustrating; coming up over that ridge that we were going up, and thinking, finally, that was it; and it wasn’t – suddenly recognizing that, really, you just don’t know where you are.” Ed Mitchell

Silently and carefully, Armstrong raised his left boot over the lip of the footpad and lowered it to the dust. Immediately he tested his weight, bouncing in the gentle gravity, and when he felt firm ground, he was still, one … Continue reading →

The majority of the second moonwalk was dedicated to reaching the rim of Cone Crater.  The wide, deep geological gold mine, which scientists believed was actually the remains of an ancient volcano.

With the Hycon camera down, Roosa would have to step in and use a Hasselblad with a 500 mm lens, to take detailed photos of the Apollo 16 potential landing site.  If Roosa did nothing else, he had to return … Continue reading →

The mortar package contained a set of grenades which were planned to be fired to distances of 500, 1000, 3000, and 5000 feet to the north of the ALSEP site.

A small plutonium source was used to power the Radioisotope Thermoelectric Generator (RTG) that would provide electric power for the ALSEP experiments.  Ed Mitchell performed the delicate maneuver of inserting the fuel capsule into the RTG.

“Al is on the surface. And it’s been a long way, but we’re here.” Alan Shepard

Suddenly the caution lights went out and the radar signals began to transmit. Within seconds the astronauts could see that its data was good. Seconds later in mission control, a jubilant Will Presley shouted, “Flight, we got radar lockup!”

While checking the lander’s guidance software, during a final practice run for the landing, engineers in mission control detected that the computer was receiving an errant signal from the abort pushbutton.

The first extended use of the Service Propulsion System engine on the Command and Service module was for the Lunar Orbit Insertion (LOI) burn.

Mitchell kept his plan a secret from NASA, knowing that the agency would be completely unreceptive to the idea. He said nothing about it to his crewmates. The test subjects had also agreed to keep quiet.

“Houston, Tranquillity Base here. The Eagle has landed.”

Suddenly, Buzz and Neil heard the high-pitched sound of the Master Alarm. On the computer display the “PROG” light glowed amber. “Program alarm,” Armstrong radioed. Quickly, Aldrin queried the computer for the alarm code,

The machine-like performance of flight crew and ground controllers continued. Each participant was in perfect harmony with the other, moving to a cadence dictated by the laws of physics and the clock.

Docking was a delicate maneuver, since both ships were traveling at nearly five miles per second, but the docking mechanism itself was one of the simplest on the entire spacecraft, and the docking procedure had been perfected on previous Apollo flights...

“The approaching dusk and the damp mistiness left by the now-departed rainstorm only enhanced the spectacular sight and the sound of the launch. Tentacles of flame erupted on either side of the bottom of the Saturn V, which seemed to … Continue reading →

The first launch window for Apollo 14 began at 15:23, Eastern Standard Time, 31 January 1971, and lasted almost four hours.

On November 9, 1970, the Apollo 14/Saturn V assembly, as tall as a 36-story building, rolled out of the Vehicle Assembly Building on the proportionally huge crawler transporter.

Even with all the problems, Shepard piloted the Lunar Module Antares to the most accurate landing of the entire Apollo program. Shepard became the fifth and, at the age of 47, the oldest man to walk on the Moon, and … Continue reading →

After the Mercury-Atlas 10 mission was canceled, Shepard was designated as the Commander of the first crewed Gemini mission, with Thomas P. Stafford chosen as his pilot.
