Space Rocket History #74 – Gemini VIII with Neil Armstrong and Dave Scott – Part 3 06.07.2018

Armstrong eased Gemini VIII toward the target at a barely perceptible speed of 8 centimeters per second. Then Armstrong gleefully reported, “Flight, we are docked!” For a brief moment, the flight controllers in Houston did not realize they had really accomplished docking. Then pandemonium broke loose…

Space Rocket History #73 – Gemini VIII with Neil Armstrong and Dave Scott – Part 2 06.07.2018

This was the most complex mission attempted to date. The primary mission objectives were to perform rendezvous and four docking tests with the Gemini Agena Target Vehicle (GATV) and to execute an ExtraVehicular Activity (EVA)…

Space Rocket History #72 – Gemini VIII with Neil Armstrong and Dave Scott – Part 1 06.07.2018

On September 20th 1965, NASA named the crew for Gemini VIII. The command pilot selected was Neil Armstrong, a civilian test pilot with much experience in the X-15 rocket research aircraft program. David Scott was selected as pilot.  Scott was the first of the Group 3 astronauts selected for a mission. The backup crew for Gemini VIII, was  Navy Lieutenant Commanders Pete Conrad and Richard F. Gordo...

Space Rocket History #71 – Agena vs. the Augmented Target Docking Adapter, with Some EVA Equipment on the Side 01.06.2018

Many doubted that Agena could be ready in time to meet Gemini’s tight launch schedules. The end of 1965 saw Agena’s usefulness in manned space flight once again called into question, but this time time a substitute target had already been approved for development…

Space Rocket History #70 – Luna 5-9 – Never Give Up 01.06.2018

During 1965 through January 1966, several significant Soviet unmanned scientific missions were launched. Five of the missions will be covered in this episode. We will begin with the Soviet Luna program.

Space Rocket History #69 – Zond 3, Venera 3, and Asterix 01.06.2018

The Zond program was one of two lunar exploration programs conducted by the Soviet Union to investigate the Moon and its vicinity. The program began in 1964 and ended in 1979. The early Zond’s 1-3 were originally designed for planetary exploration, while the latter Zonds (4-8) were sent on circum lunar flights. Additionally, the latter Zond vehicles were of a totally different in design. They were...

Space Rocket History #68 – Gemini VI & VII with Wally Schirra, Tom Stafford, Frank Borman, and Jim Lovell – Rendezvous – Part 4 01.06.2018

The Gemini Program was conceived after it became evident to NASA officials that an intermediate step was required between Project Mercury and the Apollo Program. The major objectives assigned to Gemini were: 1-To subject two men and supporting equipment to long duration flights — a requirement for projected later trips to the moon or deeper space. 2-To effect rendezvous and docking with other orbi...

Space Rocket History #67 – Gemini VI & VII with Wally Schirra, Tom Stafford, Frank Borman, and Jim Lovell – Rendezvous – Part 3 01.06.2018

From the previous episode, we have Gemini VII waiting in orbit for Gemini VI-A to launch and rendezvous.  Remember, Gemini VII could only remain in orbit for 14 days, the maximum duration of its flight.  The goal was to launch Gemini VI-A on or before day 9 of Gemini VII’s mission.

Space Rocket History #66 – Gemini VI & VII with Wally Schirra, Tom Stafford, Frank Borman, and Jim Lovell – Rendezvous – Part 2 01.06.2018

From the previous episode, it was decided that the name of Gemini VI would be changed to Gemini VI-a to distinguish it from the originally planned mission whose objective was to rendezvous with the Agena target vehicle. Gemini VII would be launched first before Gemini VI-a and it would be considered the target vehicle effectively replacing the Agena. After Gemini VII lifted off, Gemini VI-a would...

Space Rocket History #65 – Gemini VI & VII with Wally Schirra, Tom Stafford, Frank Borman, and Jim Lovell – Rendezvous – Part 1 01.06.2018

“We have had a conversation with the Carnarvon tracking station and their report keeps coming back – No joy – No joy.”  NASA Public Affairs Officer Paul Haney.

Space Rocket History #64 – Gemini V with Gordon Cooper and Pete Conrad – 8 Days or Bust -Part 2 09.05.2018

This was Flight Director Chris Kraft’s first major problem at the new Mission Control Center in Houston.  He knew the spacecraft had enough battery power for reentry even if the fuel cells failed completely, but he needed to know if there would be time enough to reach a good reentry zone, such as the mid-Pacific near Hawaii on the sixth orbit…

Space Rocket History #63 – Gemini V with Gordon Cooper and Pete Conrad – 8 Days or Bust -Part 1 09.05.2018

By this time the Astronauts were thinking about a nickname for their spacecraft, but NASA Headquarters now officially refused to allow nicknames for Gemini spacecraft. However, Gordo Cooper was not so easily put off. Pete Conrad’s father-in-law had whittled a model covered wagon, which inspired Cooper with the idea for a crew patch, that would depict a covered wagon, emblazoned with the legend “Ei...

Space Rocket History #62 – Gemini IV with James McDivitt and Edward White – The Duration – Part 3 09.05.2018

On orbit 48, after 75 hours of flight a problem arose. During a pass over the continental US the flight computer was updated. McDivitt was told to switch off the computer. He flipped the switch but the computer did not turn off. On the ground at mission control, efforts to solve the problem began immediately. For the next few orbits, the crew received instructions for trying different switch posit...

Space Rocket History #61 – Gemini IV with James McDivitt and Edward White – America’s First Spacewalk – Part 2 09.05.2018

For the first time Television coverage of the launch had an international audience, as the scene was broadcast to 12 European nations via Intelsat 1 aka the Early Bird satellite of episode 59. Heightened by the prospect of an EVA and the first use of the new Mission Control Center in Houston, interest in Gemini IV reached levels never again matched in the Gemini program…

Space Rocket History #60 – Gemini IV with James McDivitt and Edward White – Part 1 04.04.2018

The success of Gus Grissom and John Young’s Gemini 3 flight paved the way for long duration space missions. The longest U.S. manned space flight to date was Gordon Cooper’s 34 hour Mercury flight. The Soviets, however, had four long duration flights to their credit, ranging from 70 to 119 hours. It was time for the US to attempt a long duration flight.

Space Rocket History #59 – Ranger 8-9, and Intelsat I 04.04.2018

In total Ranger 9 transmitted 5,814 good contrast photographs during the final 19 minutes of flight. The last image taken before impact had a resolution of 0.3 meters per pixel. The spacecraft encountered the lunar surface after 64.5 hours of flight.  Impact occurred at 14:08:19 UT right on target in the Alphonsus crater. Impact velocity was 2.67 km/s. The spacecraft performance was excellent.

Space Rocket History #58 – Corned Beef Controversy – Gemini 3 with Gus Grissom and John Young – Part 2 04.04.2018

Grissom – What is it? Young: Corned beef sandwich. Grissom: Where did it come from? Young: I brought it with me. Let’s see how it tastes. Smells, doesn’t it. Grissom: Yes, its breaking up. I’m going to stick it in my pocket. Young: Is it? It was a thought, anyway. Grissom: Yep. Young: Not a very good one. Grissom: Pretty good, thought, if it would just hold together. Young: Want some chicken leg?...

Space Rocket History #57 – First Gemini Manned Mission – Gemini 3 with Gus Grissom and John Young 04.04.2018

The precise scope of the Gemini 3 mission remained uncertain until very nearly the eve of flight. In April of 1963, the GT-3 mission directive was “to demonstrate and evaluate the capabilities of the spacecraft and launch vehicle system, and the procedures necessary for the support of future long-duration and rendezvous missions.”  But, that was a broad scope and did not clearly specified how GT-3...

Space Rocket History #56 – First Space Walk – Voskhod 2 with Alexei Leonov and Pavel Belyayev – Part 2 04.04.2018

Leonov opened the airlocks outer hatch He was positioned on his “back” and this orientation revealed the beauty of earth in its entirety.  His heart began to race as he pushed his upper body outside and saw the deep blue vista of the Mediterranean Sea, fringed by the easily recognizable shapes of Greece and Italy and, farther east, the Crimea, the Caucasus Mountains, and the Volga River…

Space Rocket History #55 – First Space Walk – Voskhod 2 with Alexei Leonov and Pavel Belyayev – Part 1 04.04.2018

Voskhod 2 was a high risk mission.  It was the final space race victory for the Soviet Union before NASA claimed the lead and ultimately won with the lunar landing of 1969. Voskhod 2 was the peak of the Soviet Space Program.  It nearly killed its two cosmonauts but it was ultimately a success…

Space Rocket History #54 – Gemini 2 – Part 2 16.03.2018

Gemini Launch Vehicle Two’s misfortunes during August and September 1964 forced NASA to forego its goal of a manned Gemini 3 flight before the end of the year, Gemini-Titan 2 was now scheduled for mid-November 1964, and Gemini 3 for the end of January 1965…

Space Rocket History #53 – Gemini 2 – Part 1 16.03.2018

The bright outlook that was prevalent in April turned dark in the late summer of 1964 when a series of natural disasters struck the Cape. First lightning, then hurricanes, damaged the Gemini 2 launch vehicle to delay its flight long past the scheduled time.  Even if the weather had been perfect, McDonnell’s difficulties in getting Spacecraft 2 ready to fly might have compromised the schedule on it...

Space Rocket History #52 – Gemini 1 – Test Flight – Part 2 16.03.2018

One second after 11 o’clock Wednesday morning, April 8th 1964, the Titan II booster’s first-stage engine ignited. Four seconds later, the 156 ton vehicle lifted from the pad on that curiously lambent flame so distinctive of Titan II’s hypergolic propellants. Within moments, Gemini-Titan 1 vanished into the hot Florida sky, beyond reach of human senses but not electronic sensors. Telemetry data flo...

Space Rocket History #51 – Gemini 1 – Test Flight – Part 1 16.03.2018

“The primary objective of the first Gemini mission, was to prove that the Titan II was capable of launching the Gemini spacecraft into orbit within the tolerances imposed by manned space flight. The secondary objective was for the spacecraft to gather and report data.”

Space Rocket History #50 – Blue Gemini – 1963 16.03.2018

“Blue Gemini” was the tag name for an Air Force manned space flight program to develop rendezvous, docking, and transfer for military purposes, using Gemini-type spacecraft. The concept became firmer in June, when the Air Force Space Systems Division (SSD) began working on plans to use Gemini hardware as the first step in a new Air Force man-in-space program called Mods (Manned Orbital Development...
