The Hot Summer of 1971 From the author’s archives. Retired veterans of the Soviet space program, from left to right: A. G. Reshetin, B. Ye. Chertok, V. V. Vorshev, and V. F. Skvortsov at Chertok’s dacha in 2006. problems there. We just need to make sure your planners don’t put on airs, and we’ll always come to terms.” That evening Rauschenbach and Chizhikov interrupted my late-night pursuits. “It’s time to get ready to go home,” said Chizhikov. “We’re here to bum a ride off of you. Today neither of us has a car.” I glanced at my watch. It really was time. After scooping all the classified materials into the file, I telephoned the first department. “Yesterday at Pirogovo we had an incident. I wanted to drop by and see you first thing in the morning, but instead I ended up in the shop and I got all tied up,” said Chizhikov. “What happened?” “An ambulance took Aleksey Isayev straight from his garden plot to the hospital.” “He got a Czech Jawa motorcycle quite recently. Don’t tell me he crashed.” “No, that’s not it at all. It seems he had bad chest pains.” “That’s worse. Wait. Let’s find out what’s going on.” I dialed Isayev’s number on the Kremlin line. His first deputy—Vladislav Nikolayevich Bogomolov—answered. He was also the owner of a garden plot in Pirogovo. Bogomolov confirmed that Isayev had started to have intense pains 385
Rockets and People: The Moon Race near his heart. They called an ambulance from Mytishchi. 36 At the Mytishchi hospital the diagnosis was that he’d had a heart attack. Consequently, they put him on strict bed rest on his back, IV line, and shots. He, Bogomolov, imme- diately informed the ministry of this calamity. There they had a fit: “What do you mean, he’s in Mytishchi? Get him to the kremlevka immediately!” 37 An
ambulance rushed from the kremlevka to Mytishchi with a request to release the patient. The Mytishchi doctors objected. In their opinion it was risky to transport the patient in such a condition. After examining Isayev, the kremlevka medical staff supposedly said that there was absolutely no danger and that it wasn’t a heart attack at all, but pains from intercostal neuralgia. 38 They took Isayev to the kremlevka. For the time being Bogomolov couldn’t say whether Isayev had had a heart attack or neuralgia. And I had been on the verge of inviting Aleksey Isayev to fly with me to Yevpatoriya for the landing of Dobrovolskiy’s crew. I had dreamed of talking him into making a trip with me to Koktebel after the landing and spending the day there reminiscing about our prewar croquet tournaments and strolls to Kara-Dag. I reminded Chizhikov: “Remember what a fantastic time we had with Isayev in Koktebel—it’s been 31 years! Those were the good old days. Koktebel is quite close, but apparently it’s not in the cards any more for us to get there.” What should we do now? We couldn’t possibly drive home. I called Yevgeniy Vorobyev on the Kremlin line. Despite the late hour he was on the job. “I’ll try to find out. But keep in mind that at the kremlevka they don’t like it when we interfere.” Five minutes later Vorobyev telephoned. “I managed to find out that the situation is serious. Of course, they told me that they’re doing everything they can and they don’t need our help….” On 25 June 1971, Aleksey Isayev died. The staff at the Khimmash Design Bureau was stunned. 39 Isayev not only enjoyed the authority of a chief, but also the sincere love of his staff, which rarely comes to a boss from his subor- dinates. Rarely did a spacecraft get along without Isayev’s orbital correction engines. Air-defense, missile-defense, and submarine-launched missiles flew using Isayev’s engines. 36. Mytishchi is a city on the northeastern limits of Moscow. 37. Kremlevka was the nickname of the Kremlin hospital where high-ranking officials were treated. 38. Intercostal neuralgia describes severe pains due to rib muscles contracting during inhalation. 39. In 1967, Isayev’s OKB-2 had been renamed Konstruktorskoye byuro khimicheskogo mashinostroyeniya (Design Bureau of Chemical Machine Building) or KB Khimmash. 386
The Hot Summer of 1971 Isayev didn’t have many people who were jealous of him, and he had no enemies. I had known him for 35 years. All that time it seemed that not only his brain, but also his heart, burned with the flame of engineering creativity. He belonged to a rare breed of creator/manager who could arrive at work in the morning, assemble his colleagues, and say, “Everything that we thought up yesterday needs to be tossed into the trash can and forgotten. We slipped up.” Isayev was not afraid to admit his own mistakes and bravely contested popular opinion. His behavior sometimes caused outrage in the ministries when deadlines were missed because Isayev demanded that a large amount of production stock be “thrown out” like potato peelings. Simplicity, approach- ability, and unselfishness set Isayev apart from his peers. Mishin telephoned me from the firing range. “Tomorrow we have a launch. I won’t be able to fly back for Aleksey’s funeral. As an old comrade and representative of our organization, you go support the Isayevites.” It wasn’t difficult to arrange support at funerals. First Deputy Minister Tyulin headed the Funeral Commission. He explained: “There’s just one day for the funeral. On 27 June there is the N-1 launch. On 30 June there is the landing of the Soyuz-11 crew. A day later all the managers, including those from Isayev’s firm, must fly out to Yevpatoriya. That means the funeral has to take place on 28 June. The Central Committee gave instructions to have the burial at Novodevichye Cemetery. We need to quickly select the site. I’ve been told that his relatives insist on the old section of Novodevichye. It’s very difficult to find a plot there. But all the commands have been given. You in the city prepare the Palace of Culture for him to lie in state. You know the drill. The ministry will absorb all the expenses. Don’t forget about transportation. If we don’t have enough buses, rent municipal ones. Help Bogomolov if problems arise. I will come straight to the Palace first thing in the morning.” The launch of N-1 No. 6L wedged itself into our ritual schedule as a funeral salute. Liftoff took place overnight from 26 to 27 June 1971 at 2:15:52 Moscow time. Beginning in the evening, communication was established with the firing range via the high-frequency line, but we weren’t able to set up real-time transmission of telemetry parameters. We received information about what happened after liftoff in the form of not very distinct oral reports from the bunker, and then from the firing range computer center, where the telemetry systems’ information was processed in real time. All 30 first-stage engines transitioned to mode. The rocket lifted off nor- mally. Five seconds after liftoff the telemetry operators began their running commentary: “Pitch and yaw normal; roll angle is increasing.” 387
Rockets and People: The Moon Race From the first seconds, the rocket began to spin about its longitudinal axis. After 14 seconds of flight, the roll angle exceeded 8°. The gyro platform issued the AVD (emergency engine shutdown) command. The command failed to pass. It was inhibited until 50 seconds into the flight. This inhibit had been introduced after the crash of No. 5L for the safety of the launch facilities. By the 50th second of flight, the rocket had spun 60°. As soon as the inhibit was removed, all 30 engines of the first stage shut down at once. The rocket fell to the ground 20 kilometers away. If it hadn’t been for the safety inhibit of the AVD command, the rocket would have crashed a kilometer from the launch site. The blast wave, equivalent to 500 tons of TNT, would have destroyed the launch facilities for a second time. In 1948, during the testing of R-1 missiles in Kapustin Yar, Pilyugin had dared to assert to the State Commission that failures provide us with experi- ence that we don’t gain during normal launches. Recalling this, addressing Pilyugin and me at one of the accident investigation commission sessions, Barmin said with bitter satisfaction: “You have experimentally confirmed the fulfillment of my requirement for defective rockets to fall a safe distance from the launch site.” What forces spun the rocket? It seemed the answer lay on the surface—a false command from the roll-control system. This scenario has been declared the most likely in similar cases. During that very difficult, sleepless night, even I gave in to the hypnosis of that very simple explanation—that it was a failure in the roll command transmission circuit. But the more likely scenario was that the command polarity was mixed up. “The same thing happened on our first Soyuz. They could also have gotten it mixed up on a rocket,” said those taking part in the all-nighter in Podlipki, having no credible information from the firing range. Proponents of the mixed-up polarity tried to calculate the angular rate of spin. In this case, instead of the stabilization automatic control unit providing negative feedback, the control unit provided positive feedback. Rather than responding to the roll angle error with counteracting torque from the rotation control nozzles, the automatic control unit would add to and intensify the torque. By 10 a.m., according to reports from the firing range, the scenarios pointing to the culpability of the control system and also the likelihood of mixed polarity had been rejected. Georgiy Degtyarenko explained via the high- frequency communication line that the control system had fought honorably for the rocket’s life. From the very first seconds of flight, the engines’ control nozzles attempted to stop the rotation but quickly reached their stops, and the spinning continued. Perturbation torque about the longitudinal axis, which came from who-knows-where, proved to be much greater than the torque of the control nozzles. 388
The Hot Summer of 1971 That day they telephoned us relentlessly from the offices of the Central Committee, VPK, and various ministries and related organizations, convinced that the secret of the N-1 crash had already been discovered, but that we were intentionally keeping them in the dark and hiding something. Khitrik was one of the first that day to come out with a scenario, which was later proved true. “Using the reports of our comrades from the firing range, we have tried to reproduce the process on our models. The control system acts that way only when perturbation torque is five times greater than the value you noted in the baseline data. I have already informed Pilyugin of that, and he informed Mishin. Before they arrive I advise that we call together all the aero- and gas- dynamics specialists and let them try to find where this perturbation is coming from, given that we didn’t have it during the exact same seconds during the first launch.” All that I managed to do on that chaotic and difficult day was to pass on Khitrik’s doubts to the chief of the aerodynamics department, Vladimir Roshchin. “We couldn’t have committed such a large error,” he said. “Perhaps during modifications of the aft end they deformed the structure. Tell Khitrik to look for the problem in his own shop.” Alas, it all turned out to be con- siderably more complicated. This became clear after prolonged studies and labor-intensive experimental work. It wasn’t until late that evening, at home, that I was able to remi- nisce about Isayev. Katya and I sorted through memories of our meetings with him beginning in 1935: in Fili, Khimki, Koktebel, the Urals, Podlipki; strolls together through Leningrad; the commotion of children on the meadows in Pirogovo; the exclamations of “well, blow my brains out” on the occasion of both success and failure. Daniil Khrabrovitskiy—the screenwriter of the film Ukroshcheniye ognya [Taming the Fire]—was shaken when I called to inform him of Isayev’s death. 40 “His stories, his dedication, his real help with the launches of rockets enriched the film much more than I had anticipated,” said Khrabrovitskiy. “Despite your objections, after getting to know Isayev, I sent Bashkirtsev to the construction of Magnitogorsk. 41 I didn’t make up the scene with the black caviar in the cold barracks. Isayev told me about that.” 40. Daniil Yakovlevich Khrabrovitskiy (1923–1980) was a well-known Soviet director who directed Taming the Fire, the first Soviet-era fictionalization about the space program put to film. Chertok has much to say about this film in the final chapter of this volume. 41. Andrey Bashkirtsev was the lead character in Taming the Fire, representing a fictionalized version of Sergey Korolev. 389
Rockets and People: The Moon Race On the day of Isayev’s funeral, according to the established tradition, he lay in state at the Palace of Culture. However, it wasn’t long before such a throng (several thousand people) had gathered at the entrance to the building that it became clear: it would not be possible to allow everyone to pass through the hall. The Commission made an unusual decision—the casket would be car- ried out to the central square of Kaliningrad. The employees of Isayev’s design bureau very efficiently reorganized the previously written protocol. Isayev lay in an open casket in the town’s central square under the hot June sun. Fresh-cut flowers carefully placed by the casket by the hundreds of people who had come to pay their last respects were added to the many dozens of wreaths from organizations. The Hero of Socialist Labor gold medal, four Orders of Lenin, the Lenin and State Prize laureate badges of honor, the Order of the October Revolution, and a multitude of medals sparkled on red pillows. I never saw Isayev decked out in with all of these government awards when he was alive. That day Pravda came out with an obituary and picture of Isayev. After Korolev’s obituary in 1966, this was the second posthumous declassification. Aleksey Mikhaylovich Isayev was among the first creators of rocket engines and the head of a design staff that created a whole series of engines for missile and space technology. The engines created under the leadership of A. M. Isayev were installed on Vostok, Voskhod, and Soyuz piloted spacecraft and on automatic interplanetary stations…. Aleksey Mikhaylovich was one of the designers of an airplane that performed the world’s first flight using a reactive engine on 15 May 1942. In 1944, A. M. Isayev became the head of a leading engine building design organization…. Below the obituary were the signatures of Brezhnev, Podgornyy, Kosygin, other members of the Politburo, ministers, and also Tabakov, Tyulin, Glushko, Grushin, Lyulka, and Kuznetsov. It is inexplicable why the Central Committee dared place the signature of Grushin—a developer of air-defense and missile- defense missiles—under the obituary and drew the line at publishing the surnames of the main consumers of Isayev’s engines—Makeyev and Mishin. 42 42. Petr Dmitriyevich Grushin (1906–1993) was one of the most powerful and famous chief designers in the Soviet defense industry. He headed OKB-2 (later known as MKB Fakel) from 1953 until his death; this organization designed many important air-defense and antiballistic missiles in the Soviet military arsenal. 390
The Hot Summer of 1971 Tyulin opened the funeral ceremony. His speech repeated the text of the obituary printed in Pravda. Before my speech I was handed a note: “Don’t mention anything about projects for Makeyev or missiles.” I couldn’t find the speech that I’d written and so I spoke extemporaneously. Later I was told that my speech was “from the heart.” The only words I remembered were that “Isayev was a real human being and a great engineer.” Makeyev was deprived of the right in his eulogy to mention Isayev’s decisive role in the strategic missiles that Makeyev had developed for submarines. 43 He got out of that difficulty by emphasizing Isayev’s human qualities. According to established tradition, a second funeral ceremony took place at Novodevichye Cemetery. Other orators spoke more briefly. Not everyone got to throw a handful of earth into the grave. In the old section of Novodevichye with thousands in attendance, it was anything but easy. After filling the grave, the gravediggers with their professional knack erected a hill of wreaths and fresh-cut flowers. I had arranged with [my wife] Katya, who had dozens of acquaintances here, that if we were to lose one another in the multitude of people at the cemetery, we would meet up in the parking area. I wanted to walk through to the graves of Boguslavskiy and Voskresenskiy. 44 For me this was a visceral need. That day, two true comrades of mine had been joined by a third, perhaps my closest. While I was standing at Voskresenskiy’s grave an unfamiliar woman approached me. “You don’t recognize me?” I looked at the no-longer-young, somehow imperceptibly familiar face under the mop of frizzy gray hair and confessed that I didn’t recognize her. “It’s me, Mira, have you forgotten?” After embracing, I asked: “But where’s Oleg?” 45 “Oleg has been gone for a long time. He just couldn’t deal with the tranquil life. I have a candidate of sciences degree. It’s interesting work, right near here on Pirogovskaya Street. I have two children. There’s no time to be bored. I saw the obituary in the newspaper and came to say goodbye to Isayev. I remembered him as a gallant knight, although back then he didn’t have a single medal.” “He really was a gallant knight,” I said. “But unlike Don Quixote, he possessed the talent of an engineer and he performed real feats. He didn’t do 43. Isayev’s organization designed engines for several Makeyev rockets, including the R-17, R-27, R-27M, R-27K, R-27U, R-29, R-29M, R-29R, R-29RM, and R-39. 44. Leonid Voskresenskiy and Yevgeniy Boguslavskiy had died in 1965 and 1969, respectively. 45. Author’s note: I wrote about Oleg Bedarev and his wartime girlfriend Mira in Volume I of my memoirs (pp. 314–315). 391
Rockets and People: The Moon Race battle with windmills. But he worked on fantastic designs without losing his common sense.” Mira opened her bag, pulled out an envelope, and handed it to me. “What’s this?” “You’ll see.” “Let’s walk to my car, Katya is waiting there, we’ll drive to the funeral reception.” “No. Soon everyone will be leaving; I want to be here alone for a while.” It wasn’t until I got home that I opened the envelope. It contained a photo- graph from the summer of 1945: Oleg Bedarev and I. We were both in military uniform. Printed on a sheet of onionskin paper were poignant lines of poetry. Oleg had performed them while he played his guitar at our last “fireside” get-together.
The next morning, 29 June 1971, I flew to Yevpatoriya with Kerimov and a group of Isayev’s coworkers who had stayed on for the funeral. There everyone had already prepared for the communication sessions for undocking, subsequent spacecraft orientation, deorbit, and landing. Minister Afanasyev and Mishin were supposed to fly in from the firing range. However, the failure of N-1 No. 6L had not yet been explained, and they did not feel that they could depart for Yevpatoriya. Tregub reported to the State Commission that the crew, having spent around 23 days in space, had set a record. They had conducted experiments with the military’s OD-4 optical sight/range finder, with the Orion ultraviolet- range observation system, and with the secret Svinets (Lead) radar system. They had photographed Earth, performed spectrographic studies of the horizon, and conducted experiments on gamma flux intensity and on a procedure for 392
The Hot Summer of 1971 manual orientation of the station. Tentatively, this very intense program of scientific, military, medical, and technical experiments should be considered fulfilled. The final report would be done after the materials that the cosmonauts delivered to the ground were processed. The crew spent the last two days deactivating the orbital station, packing up materials, and activating and preparing the spacecraft. The undocking com- mand was supposed to be issued on 29 June at 2125 hours. After separation from the station, two orbits were allocated for preparation for descent. The crew would perform manual orientation outside our coverage zone and would transfer control to the gyro instruments. NIP-16 would issue the command to activate the descent cycle; NIP-15 would stand by in reserve. An SKTDU deboost burn would take place at 0147 hours on 30 June. 46 Vorobyev confirmed that, according to the physicians’ findings, the condi- tion of the cosmonauts during the last few days was good. No one expected anything sensational at the traditional nocturnal meeting in the cramped control room of NIP-16. All commands to the vehicle were routed without a glitch. The crew reported the execution of all operations on time, without causing any aggravation on the ground. Everything was proceeding calmly and according to schedule. The ship-based tracking stations received information from the spacecraft as it passed over them and reported in real time that the engine had executed the deboost burn at the calculated time and the integrator had shut it down. The Command and Measurement Complex and GOGU accumulated good experience monitoring the spacecraft during the landing orbit. After engine shutdown, the spacecraft left the coverage zone of the ship-based tracking stations located in the Atlantic. Separation took place over Africa—the Habitation Compartment and Instrument-Systems Compartment were jettisoned from the Descent Module. The Descent Module did not have a radio telemetry system. We had hoped to hear about what had happened after separation in the cosmonauts’ oral report before entry into the atmosphere when the hot plasma would shut down the Zarya system’s slot antenna. A Mir multichannel automatic recording unit had been installed to record the processes in the Descent Module. After the death of Komarov, two Olegs—Sulimov and Komissarov—and their comrades at the Institute of Measurements perfected this stand-alone recorder, increasing its thermal protection and mechanical strength. 47 46. SKTDU—Sblizhayushche-korrektiruyushchaya tormozhnaya dvigatelnaya ustanovka (Approach and Correction Braking Engine Unit). 47. This was the Scientific-Research Institute of Measurement Technology (NII IT), which had spun off from TsNIImash in July 1966. NII IT was responsible for developing data sensors and recording devices for various Soviet spacecraft. 393
Rockets and People: The Moon Race “We asked Dobrovolskiy the whole time to give us a running commentary as soon as the Descent Module enters our coverage zone, but he hasn’t said a word,” complained Yeliseyev. “It’s strange that Volkov is quiet. During the last session he was very talkative.” “When you and Shatalov descended,” I affirmed, “we saw how effective the slot antenna was. Shatalov’s running commentary replaced telemetry for us.” “Before undocking, the ‘hatch closed’ indicator for the hatch between the Descent Module and the Habitation Compartment didn’t light up. Volkov was clearly nervous, but he quickly figured it out and stuck some bandage tape under the limit switch that registers hatch closure. Then they were quite wordy in their running commentary,” said Tregub. “They’re still doing great,” I said, sticking up for them. “They’re the first crew of a Long-Duration Orbital Station. They’ve withstood an unscheduled flight and for one thing, let’s tell it straight, they performed a very intense program.” A report came over the loudspeaker: “The space monitoring service track- ing the Descent Module per prognosis.” Finally, the long-awaited report arrived: “General Kutasin’s service reports that airplanes have spotted the Descent Module. 48 Parachute descent is in prog- ress. Per prognosis the overshoot is around 10 kilometers, no more, relative to the calculated touchdown point. Helicopters are flying out to the landing site.” After about 20 minutes we began to get nervous. No more reports were coming in from the landing area. The officer in contact with the search and rescue service felt guilty. We pelted him with a flurry of rebukes, but he was unable to tell us anything. State Commission Chairman Kerimov had the duty of being the first to report to Moscow—to Smirnov and Ustinov—about the successful completion of the mission. But he found himself cut off from communication with the landing area. “It’s not General Kutasin’s fault! Most likely, Commander-in-Chief of the Air Force Aviation Marshal Kutakhov has taken over communication and has ordered Kutasin not to report without his knowledge,” was the explanation that an experienced communications operator gave. 49 Around 30 minutes after the calculated landing time, Kerimov decided to complain to Ustinov about the behavior of Air Force Commander-in-Chief Kutakhov. It took another 10 minutes to connect with Ustinov. The room fell silent. Finally Kerimov gave the sign: “Quiet!” But this time we heard 48. Major-General Aleksandr Ivanovich Kutasin (1903–1978) headed the Air Force’s search and rescue service for the Soviet human spaceflight program. 49. Marshal Pavel Stepanovich Kutakhov (1914–1984) served as Commander-in-Chief of the Soviet Air Force from 1969 to 1984. 394
The Hot Summer of 1971 no complaints about Kutakhov. Kerimov said nothing. He hung up. With a changed expression on his face, Kerimov began to recount what he had heard from Ustinov. “Two minutes after landing, a rescue crew from a helicopter ran up to the Descent Module. It was lying on its side. Externally there was no damage at all. They knocked on the side. No one answered. They quickly opened the hatch. All three were sitting in their seats in tranquil poses. There were dark blue spots on their faces. Blood was running from the nose and ears. They pulled them out of the Descent Module. Dobrovolskiy was still warm. Doctors continued to perform artificial resuscitation. According to their reports from the landing site, death was the result of asphyxiation. No foreign odors were detected in the Descent Module. Measures were taken to evacuate the bodies to Moscow for examination. Specialists from Podlipki and the Cosmonauts Training Center flew out to the landing site for an investigation.” In the total silence someone said: “It was depressurization.” The horrible news stunned everyone. No one delighted in the clear blue sky or in the vast expanse of the mirror-smooth sea from whence the sweet, fresh morning air wafted through the wide-flung windows. At 11:30, the State Commission and everyone who could fit onto the airplane departed from the Saki airfield for Moscow. A small group stayed on in Yevpatoriya to monitor the flight of DOS No. 1, which went down in the history of cosmonautics as Salyut 1. The orbital corrections prepared and performed for its missions supported the station’s flight until October. But now this no longer mattered. According to the disaster investigation results, so many measures would have to be taken that, in the best-case scenario, the next piloted Soyuz would not be able to fly until early 1972. For the N-1, the break in flight-development testing, regardless of what the other commission found, would also drag on for at least another six months. These were the thoughts running through our heads on the airplane. (In fact, considerably more time was needed for all the modifications. Test flights of unpiloted Soyuzes didn’t start up again until June 1972. 50 )
group of specialists headed by cosmonaut Aleksey Leonov and Descent Module developers Andrey Reshetin and Vladimir Timchenko looked over the module and checked it for leaks. They were not able to detect any off-nominal loss of pressure integrity. They removed the magnetic tape from the Mir recorder and 50. This was the Kosmos-496 mission, flown from 26 June to 2 July 1972. 395
Rockets and People: The Moon Race quickly dispatched it. Everyone was confident that after it was processed the cosmonauts’ cause of death would immediately become apparent. Moscow met us with such a heat wave that the Crimea seemed cool by comparison. Just a week before, I had stood in the honor guard by Isayev’s casket in Kaliningrad. Now they were preparing the Red Banner Hall of the Central Building of the Soviet Army for a funeral ceremony of three cosmonauts at one time. All three were posthumously awarded the title of Hero of the Soviet Union. It was the second time for Volkov. From the Central Building of the Soviet Army, through a vast throng of people, the funeral procession headed to Red Square. The urns containing the cosmonauts’ ashes were immured in the Kremlin Wall.
