Cook Electric Company submitted a proposal to the McDonnell Aircraft Corporation as a part of a preliminary study and design effort by McDonnell for a manned satellite. McDonnell, prior to being awarded the Mercury prime development contract in February 1959, spent 11 months under a company research budget working on a manned orbital spacecraft concept.

Defense Secretary Robert S. McNamara announced that negotiations with the Communications Satellite Corporation for a defense communications network were terminated, and he directed the Defense Department to proceed with the full development of a military satellite communications system to be built by Philco-Ford. This was the Initial Defense Communications Satellite Program (IDCSP).

North American began redesigning the side hatch mechanism in the CM to satisfy the requirement for extravehicular transfer from Block II spacecraft. Two basic modifications to the Block I mechanism were required: (1) enlarging it to overcome thermal warpage; and (2) adding some hinge retention device to secure the hatch once it was opened.

During launch preparations with the fuelled Proton / L1, there was an explosion, killing three technicians. Their death alone indicates the area around the pad was unsafe at the time. The Block D oxidiser tank of the L1 exploded - the first such failure in 30 uses. The rocket and spacecraft were relatively undamaged. The third stage of the Proton had some external damage due to exposure to the Block D's fuel, but it can be cleaned. The real question is how to remove the L1 spacecraft on the pad. A helicopter could hoist the spacecraft away, but the available Mi-6 or V-10 helos can lift only 8 to 10 tonnes, and the L1 weighs 14 tonnes. A V-10 crew is sent to investigate the possibilities anyway. Some engineers suggest just firing the BPO abort tower and lifting the capsule away from the stack! Emergency political and military meetings are held at the cosmodrome to discuss the impending invasion of Czechoslovakia.

The Lunar Science Institute's summer study on post-Apollo lunar science arrived at a number of conclusions and recommendations. Some conclusions were: Lunar science would evolve through three rather distinct phases. For two years immediately following Apollo 17, high priority would be given to collection, organization, and preliminary analysis of the wealth of information acquired from the exploration of the moon. In the next two years (1975 and 1976), emphasis would shift to a careful first look at all the data. In the next years, investigations would be concentrated on key problems.

Soyuz 19 initial orbital parameters were 220.8 by 185.07 kilometres, at the desired inclination of 51.80°, while the period of the first orbit was 88.6 minutes. On 17 July the two spacecraft docked. The crew members rotated between the two spacecraft and conducted various mainly ceremonial activities. Leonov was on the American side for 5 hours, 43 minutes, while Kubasov spent 4:57 in the command and docking modules.

After being docked for nearly 44 hours, Apollo and Soyuz parted for the first time and were station-keeping at a range of 50 meters. The Apollo crew placed its craft between Soyuz and the sun so that the diameter of the service module formed a disk which blocked out the sun. After this experiment Apollo moved towards Soyuz for the second docking.

Three hours later Apollo and Soyuz undocked for the second and final time. The spacecraft moved to a 40 m station-keeping distance so that an ultraviolet absorption experiment could be performed. With all the joint flight activities completed, the ships went on their separate ways.

This flight marked the culmination of the Apollo-Soyuz Test Project, a post-moon race 'goodwill' flight to test a common docking system for space rescue. 15 July 1975 began with the flawless launch of Soyuz 19. Apollo followed right on schedule. Despite a stowaway - a 'super Florida mosquito' - the crew accomplished a series of rendezvous manoeuvres over the next day resulting in rendezvous with Soyuz 19. At 11:10 on 17 July the two spacecraft docked. The crew members rotated between the two spacecraft and conducted various mainly ceremonial activities. Stafford spent 7 hours, 10 minutes aboard Soyuz, Brand 6:30, and Slayton 1:35. Leonov was on the American side for 5 hours, 43 minutes, while Kubasov spent 4:57 in the command and docking modules.

After being docked for nearly 44 hours, Apollo and Soyuz parted for the first time and were station-keeping at a range of 50 meters. The Apollo crew placed its craft between Soyuz and the sun so that the diameter of the service module formed a disk which blocked out the sun. This artificial solar eclipse, as viewed from Soyuz, permitted photography of the solar corona. After this experiment Apollo moved towards Soyuz for the second docking.

Three hours later Apollo and Soyuz undocked for the second and final time. The spacecraft moved to a 40 m station-keeping distance so that the ultraviolet absorption (UVA MA-059) experiment could be performed. This was an effort to more precisely determine the quantities of atomic oxygen and atomic nitrogen existing at such altitudes. Apollo, flying out of plane around Soyuz, projected monochromatic laser-like beams of light to retro-reflectors mounted on Soyuz. On the 150-meter phase of the experiment, light from a Soyuz port led to a misalignment of the spectrometer, but on the 500-meter pass excellent data were received; on the 1,000-meter pass satisfactory results were also obtained.

With all the joint flight activities completed, the ships went on their separate ways. On 20 July the Apollo crew conducted earth observation, experiments in the multipurpose furnace (MA-010), extreme ultraviolet surveying (MA-083), crystal growth (MA-085), and helium glow (MA-088). On 21 July Soyuz 19 landed safely in Kazakhstan. Apollo continued in orbit on 22-23 July to conduct 23 independent experiments - including a doppler tracking experiment (MA-089) and geodynamics experiment (MA-128) designed to verify which of two techniques would be best suited for studying plate tectonics from earth orbit.

After donning their space suits, the crew vented the command module tunnel and jettisoned the docking module. The docking module would continue on its way until it re-entered the earth's atmosphere and burned up in August 1975.

The first flight of the Advanced Inertial Reference Sphere (AIRS) occurred on STM-11W from Vandenberg AFB. The purpose of the AIRS flight test was to demonstrate the technical feasibility of the floating ball reference sphere. The flight was successful. It was also the first flight of the missile performance measurement system.

Air Force Chief of Staff General Allen directed AFSC to develop and deploy a vertical shelter engineering prototype to obtain data on construction, operations, and cost. Both the vertical shelter and the hybrid in-line trench concepts were to be developed as options for full-scale engineering development, and information on these was to be presented at AFSARC II in preparation for DSARC II.

Defense Meteorological Satellite Program. Although there was a press release immediately after the launch (by the spacecraft SPO) that said the 2nd stage motor exploded, in reality the problem was found to be due to poor design of the electrical connectors between the 2nd and third stages and a separation problem that ripped the wiring out of the spacecraft.

This French scientific mission goes according to plan. Haignere stated that all experiments are going well. The only problem is the fact that they have a lot of work to do. On 14.07.93 due to their work a direct TV-report in which a conversation with President Mitterand had to be cancelled or did not take place due to lack of comm. channels. H. is feeling well. No space sickness, no headache or other pains, he sleeps well and has a good appetite. H. praises the good amicable sphere among the crew members, which guarantees a good co-operation. H., call F6Mir, enjoys the possibilities of radio-amateurism: as soon as France is in range he has long conversations with French radio-amateurs. On 11.07.93 in orb. 42293, 1324 UTC, he also got the opportunity to speak with his parents. He had to ask one of the amateurs to leave the frequency (144.475 mc) for he was not able to hear his mother. On this frequency also a lot of P/R traffic. H.'s presence on board Mir caused a remarkable increase of French amateur-calls on Mir's P/R.

Mir-crew: Manakov is still captain of the Mir-complex and this he shows clearly. During every pass he tightly holds the microphone. Now and then Polishchuk and Serebrov can be heard; Tsybliyev, who has to take over command one of these days, rarely speaks with TsUP.

Progress-M17: During the experiment 'Rodeo' on 3.07.93 this freighter undocked from the Mir station while Soyuz-TM17 was waiting for the docking port freed by Progress-M17. Progress-M17 undocked at 1553 UTC. Soyuz-TM17 docked to Mir at 1624 UTC. The return-capsule of Progress-M17 landed safely in Kazakhstan at 1802 UTC.

Soyuz-TM16: With this ship, now still attached to the Kristall- Module, Manakov, Polishchuk and Haignere will return to earth on 22.07.93. The landing is expected at about 0630 UTC.

The preparations for the internal EVA were still going on successfully (as far as this can be ascertained by monitoring) when Tsibliyev reported that he had hearth rhythm problems. Initially he discussed this with a doctor, first name Irina, who was not able to diagnose the case and so she did not prescribe medicine. Later on Tsibliyev asked for permission to swallow a pill and for an answer on his question whether he would be able to do the difficult IVA or not. The problem emerged yesterday and now it is known that higher 'doctors' are trying to find a solution. During radio conversations in the passes of orb. 65141 and 65142 it was obvious that the complaints of Tsibliyev will effect further plans.

The exercise which was on schedule for today (using Kvant-2 to imitate the IVA into Spektr) had been put back and that this was also the case with the IVA itself. Today Tsibliyev declared that if he could have a week to recover and nothing special would occur he wished to do the IVA himself. From the beginning, for instance during the collision , he was so involved in this all that he considers this as his duty. TsUP obviously had other ideas and asked Foale to take the microphone. Foale stated that he had no objections and that he would be very pleased to accomplish this task. He was sure that Tsibliyev would give him the right instructions. Tsibliyev possibly agreed with the possibility that Foale would replace him.

Foale added that he already knows how to handle the spacesuit Orlan-DMA. Tsibliyev said that the spacesuits were ready for the operation. A few orbits later Mir communicated with TsUP via Altair-2 in phone, but they also exchanged images. For a long time the cosmonauts were in the P.Kh.O (transition section) involved in technical preparations for the IVA. Tsibliyev was the most active crew member during these preparations and did not show signs that he had health- or stress problems. Probably he wants to recapture his place as spacewalker nr. 1. Whether Tsibliyev or Foale will do the IVA is not yet known. The IVA has been put back abt 10 days. Foale did not participate in the discussions from the P.Kh.O. Now and then, but not often, Lazutkin could be heard.

Altair-2:

The crew succeeded in restoring the communications from and to Mir via this geostationary satellite. Initially they had problems with their phone during the transmission of TV-images. On Sunday (13.07) they showed little papers with that what they wanted to tell their relatives and friends. On 14.07 they adjusted the installation in which Foale substantially participated. Today, 15.07, the so called Ku-band was fully in use during some passes. Chris v.d. Berg, NL-9165/A-UK3202.

International Space Station activities continue to focus on the maintenance of on-board batteries to ensure as long a life as possible and the troubleshooting of a balky antenna on the backup communications system. Flight controllers continue to watch over ISS systems as well, despite two instances of power outages at the Russian Mission Control Center late last week and again today.

The Minuteman II flew a suborbital trajectory with an apogee of around 1600 km and reentered near Kwajalein Atoll. The Boeing Minuteman II had an M55E1 first stage, an SR19 second stage and an M57A1 third stage. One large decoy balloon was used, 1.7 meters in diameter, slightly smaller than the balloon used earlier as a decoy. This new decoy still had an IR signature much brighter (approximately three times) than that of the mock warhead.

Successful ABM test, a repeat of IFT-5. The US Army then launched the Lockheed Martin PLV, consisting of SR19 and M57A1 stages, to an intercept it at an altitude of 225 km. The test was part of the Ground-Based Midcourse Defence Segment of the NMD (National Missile Defense) program.The prototype X-Band radar (XBR) used in IFT-6 could not process all the information it was receiving quickly enough, causing it to falsely report that the interceptor had missed its target. But in fact the interceptor functioned correctly, and the kill was confirmed by sensors on a satellite, a 747 jet, and ground stations. Starting in IFT-6, a recurring error was identified in the EKV's target position estimation data. The glitch never interfered with the effectiveness of the EKV, and was attributed to degraded EKV inertial measurement unit output data caused by electromagnetic interference from test-unique cabling.

The astronauts removed thermal covers from the Quest airlock module. Handrails were installed on Quest and the oxygen and nitrogen tanks stored in the Spacelab pallets. The Station SSRMS arm grappled Quest, unberthed it from Atlantis, and docked it to the Unity module. Quest was firmly bolted to Unity's +X CBM at 0740 GMT and the astronauts returned to the airlock just over an hour later.

Crew: Polansky, Hurley, Cassidy, Marshburn, Wolf, Payette. Deliver to the ISS and install the Kibo Japanese Experiment Module Exposed Facility (JEM EF); Kibo Japanese Experiment Logistics Module - Exposed Section (ELM-ES); and Spacelab Pallet - Deployable 2 (SLP-D2).

Ejected from the Endeavour on 30 July at 12:34 GMT. Dragonsat consisted of two 1.5 kg cubesats, BEVO-1 from the University of Texas at Austin and Aggiesat 2 from Texas A&M University. The two satellites were ejected attached to each other, but failed to separate as planned.
