Orbit: Heliocentric orbit.
Decayed: n/a
Mission: Pioneer 5 successfully reached heliocentric orbit between Earth and Venus and demonstrate deep space technologies and provide the first map of the interplanetary magnetic field. Developed by Space Technology Laboratories Inc., the 43.2-kg spacecraft was launched for NASA by the Air Force Ballistic Missile Division (AFBMD). The spacecraft had originally been intended for a Venus flyby, but the mission was switched to a solar flyby. Controllers maintained contact with Pioneer 5 until 26 June 1960, to a record distance of 36.2 million kilometers from Earth. The probe confirmed the existence of previously conjectured interplanetary magnetic fields.
     Pioneer V produced first data on the nature of interplanetary space, including solar flare effects in interplanetary space which were compared with Earth-orbiting satellite readings, and sent back telemetry 36.2 million kilometres from Earth on 26 June 1960 (a communications record).

Mission: TIROS I was the world's first weather satellite to test the experimental television techniques leading to a world-wide meteorological satellite information system. It also was the first satellite to test sun angle and horizon sensor systems for spacecraft orientation.  The main objective of the TIROS program was to demonstrate the feasibility and capability of observing the Earth's cloud cover and weather patterns from space. Although the program was experimental, this first space-borne system demonstrated the capability to acquire information which meteorologists could use immediately in an operational setting.  TIROS I was operational for only 78 days and proved that satellites could be a useful tool for surveying global weather conditions from space
     The spacecraft was 107 cm in diameter, 48 cm high and weighed 112,5. kg. The craft was made of aluminum alloy and stainless steel covered by 9200 solar cells. The solar cells served to charge the nickel-cadmium (nicad) batteries. Three pairs of solid-propellant spin rockets were mounted on the base plate. Two television cameras were housed in the craft, one low resolution and one high resolution. A magnetic tape recorder for each camera was supplied for storing photographs while the satellite was out of range of the ground station network. The antennas consisted of four rods from the base plate to serve as transmitters and one vertical rod from the center of the top plate to serve as a receiver. The craft was spin-stabilized and space oriented (not Earth-oriented). Therefore, the cameras were only operated while they were pointing at the Earth when that portion of the Earth was in sunlight. The video systems relayed thousands of pictures containing cloud-cover views of the Earth. Early photographs provided information concerning the structure of large-scale cloud regimes..
     “For the first time, man had a complete look at the weather over a large segment of the Earth’s surface,” said Chief of the U.S. Weather Bureau. He also reports  that getting the same information contained in the cloud structure photographs taken by the Tiros I would have required thousands of weather ships over the Pacific.

Decayed: ?
Mission: After the spectacular success of Luna 3, this Luna was to return more detailed photos of the lunar far side. The Ye-3 class vehicle was essentially a Ye-2A probe using a modified radio-telemetry system, but with the old Yenisey-2 imaging system. During the launch, the probe received insufficient velocity after premature third-stage engine cutoff. It reached an altitude of 200,000 kilometers and then fell back to Earth and burned up in Earth’s atmosphere, much like some of the early American Pioneer probes.

Mission: This last “first-generation” Soviet lunar probe was designed to photograph the far side of the Moon. Unfortunately, it never left Earth’s atmosphere since, 10 seconds after lift-off, the launch vehicle began to fall apart. As each strap-on fell away, parts of the booster landed separately over a large area near the launch site. Thundering explosions broke windows in many nearby buildings.

Ranks: 46th civilian spacecraft (14th Soviet) ; 14th Soviet spacecraft (14th Soviet)

Launch: 15 May 1960 (probably at 0h00 UT), from Baykonur Cosmodrome's LC-1, by an A-1/"Vostok" (8K72 L1-11).
Orbit: Initial : 312 km x 369 km x 65°
Later : 307 km x 690 km x 65° (accidentally boosted) 
Decayed: 15 October 1965
Mission: The first piloted spaceship ever launched: a 4,540-kg craft (including 2.5 tons capsule) containing a "dummy" spaceman. The primary goal of the mission was to test the basic elements of the vessel, in particular the complex Chayka orientation system, which would put the spacecraft in the proper attitude for reentry. This first Vostok 1 spacecraft was a subvariant designated the 1KP (or Vostok 1P), with the "p" denoting that it was a simple ("prostoy") spacecraft not designed to be recovered from orbit. The spacecraft had no thermal shielding for the spherical descent apparatus and no life support system. Instead of the large ejection seat that would carry a pilot, it carried a mock-up of the contraption to simulate the correct loads. Unlike later Vostok spacecraft, two solar panels shaped like semicircles were installed on a boom heading out forward from the descent apparatus. This system, designated Luch ("ray"), would provide power to the spacecraft as an experiment to evaluate the effectiveness of solar power over chemical batteries. Although the vehicle would burn up on reentry, telemetry data would indicate whether the spacecraft had been properly angled. Total spacecraft mass was 4,540 kilograms. As soon as the spacecraft reach orbit, it was simply designated Korabl-Sputnik ("satellite-ship") and there was no indication that the mission had any relevance to a piloted space effort. 
     Planned to last three or four days, the flight proceeded without incident, with successful tests of the electrical and power source systems. Reentry was scheduled for the early morning of May 19. Prior to the scheduled firing of the TDU-1 engine, the control group detected anomalies in the primary system of attitude control, which used the infrared sensor. Although the system as a whole seemed to be functioning fine, the sensor itself was not responding correctly. On the sixty-fourth orbit. the primary system malfunctioned, and the fourteen thrusters inserted the spacecraft into a wrong attitude. The TDU-1 retrorocket automatically fired on time at 2h52 hours Moscow Time, but instead of reentering the atmosphere, the spaceship was boosted into a higher orbit. Its descent capsule decayed more than five years later.

Orbit: None.
Mission: Second test of a Vostok 1 manned spacecraft. While having the old set of orientation systems, this spacecraft was far more advanced than its modest predecessor (Korabl Sputnik 1), since it was equipped with an operational life support system and a means of recovery. Two dogs, Chayka and Lisichka, were trained to fly into orbit on board. The test went awry right from the beginning: just nineteen seconds after launch, the booster began "to fork to one side" as a result of a fire and a breakdown of the combustion chamber in one of the strap-on engines (in Blok G). The inert strap-on broke away from the main vehicle, and the booster eventually exploded into pieces 28,5 seconds after lift-off. Although the descent apparatus separated from the stack, the explosion killed both passengers.

In addition, there were twenty-eight mice and two white rats outside the ejection seat, but within the descent apparatus. Two internal TV cameras provided views of the dogs during the spaceflight. The spacecraft itself was fully equipped with a functioning catapult, a life support system, and parachutes. Its total mass in orbit was about 4,600 kilograms.
     Upon successfully entering orbit, the spacecraft was named the "Second Korabl-Sputnik". Throughout the one-day mission, doctors continuously monitored the medical condition of the dogs while various parameters of the life support system were given a rigorous workout. The biomedical support group was able to observe the reactions of the dogs while in flight. The pictures coming back were not encouraging: initially, the dogs appeared deathly still, and without the incoming data stream on their life signs, it would have been impossible to tell if they were alive or not. Later, they became more animated, but their movements seemed convulsive. Belka squirmed and finally vomited on the fourth orbit. A number of scientific experiments were carried out during the mission, including those for the detection of cosmic rays and the monitoring of high-energy emissions in the ultraviolet and x-ray wave lengths.
     Telemetry showed that the infrared orientation system had failed (as with Korabl-Sputnik 1). Engineers recommended using the backup solar orientation system. The latter performed without any anomalies on the spacecraft's eighteenth orbit, and the descent apparatus successfully entered Earth's atmosphere at the correct angle. The catapult system operated on schedule and ejected the cabin with the dogs in the mock-up of the ejection seat. The cabin landed safely by parachute only ten kilometers from the designated point of touchdown in the Orsk region in Kazakhstan after a one-day, two-hour spaceflight. Belka and Strelka thus became the first living beings recovered from orbit. The spacecraft itself was only the second object retrieved from orbit. the American Discoverer 13 had preempted Korabl-Sputnik 2 by nine days. Doctors found both dogs in good condition despite the concerns during the mission. Extensive physiological tests proved that there had been no fundamental changes in their health. This flight verified almost all the primary elements of the spacecraft design.

Orbit: None
Mission: This Pioner P-30 / Able VA had a slightly different instrument complement from that of its predecessor (Pioneer P-3), but it had similar mission goals. The 175.5-kg probe was to enter lunar orbit about 62.5 hours after launch with parameters of 4,000 x 2,250 kilometers in a period of 10 hours. Although the first stage performed without problems during the launch, the Able second stage ignited abnormally and shut down early because of an oxidizer system failure. The third stage never fired, and the probe burned up in Earth’s atmosphere 17 minutes after launch. Although the mission was a failure, ground controllers fired Able VA’s onboard liquid propellant hydrazine rocket engine – the first time that an onboard motor was fired on a space vehicle. Later, on 15 November 1960, NASA announced that two objects from the Able VA payload had been found in Transvaal, South Africa.

Launch: 10 October 1960 at 14h28 UTC, from Baykonur Cosmodrome's LC-1, by an A-2-e/"Molniya" (8K78 L1-4M).
Orbit: None.
Mission: This was the first attempt by humans to send spacecraft to the vicinity of Mars and was the first of two Soviet Mars spacecraft intended to fly past Mars. (The Mars flyby was planned for 13 May 1961.) The 480-kg spacecraft initially included a TV imaging system and a spectro-reflectometer (to detect organic life on Mars), but mass constraints forced engineers to remove both instruments a week before launch. The mission profile called for the probe to first enter Earth orbit and then use a new fourth stage (called “Blok L”) to gain enough additional velocity to fly to a Mars encounter. During the launch, violent vibrations caused a gyroscope to malfunction. As a result, the booster began to veer from its planned attitude, the guidance system failing at 309 seconds, and the third-stage engine was shut down after the trajectory deviated to a pitch of greater than 7 degrees. The payload eventually burned up in Earth’s atmosphere over eastern Siberia.

Orbit: None.
Mission: The SAMOS 1 payload had a mass of 1860 kg including the Agena. It was probably a Program 101 flight and carried the E-1 camera Component Test Payload and F-1 ferret research and development test payload. an Agena failure meant it did not reach orbit.
Launch: The Atlas guidance system failed but the Atlas flew successfully. However, at launch an Agena umbilical failed to separate cleanly and the nitrogen attitude control gas leaked out, so that Agena could not be stabilized after separation and fired in the wrong direction. 
Notes: The SAMOS satellite system was part of the WS-117L initial military satellite program. It tested visual surveillance (real time radio readout of scanned photographs), film recovery and ferret electronic intelligence. The original SAMOS, Program (or Project) 101, consisted of an Agena A and carried the E-1 0.15-meter focal length strip camera and an F-1 ferret payload. E-1 was a component test payload. Some documents indicate that the F-1 was a separate payload, possibly a subsatellite, but it seems more likely that it remained attached to the Agena. Three Program 101 satellites were built and two were launched.

The Nedelin Catastrophe

      On 24 October 1960, a major disaster happen at the Baykonur Comodrome, killing more than a hundred of personnel, including one of the most important figures of the Soviet missile and space programs. The tragedy was first heard of in the West in the 1970s and since it had happened during a period favorable to launch Mars probes, it was considered a major blow to the Soviet space program. It was only in the 1990s that the full account was revealed (and the fact that it had nothing to do with Mars exploration). Here what had happened.
     Numerous important officials were at Baykonur to witness the first launch of the R-16 ICBM which, when it will become operational, will finally give the Soviet Union an active and large-scale strategic deterrent against the United States. Since the R-16 was fueled by storable hypergolic and highly toxic propellants, there had been much difficulty prior to launch, especially in fueling procedures, which caused great consternation at the site. The first launch was originally set for October 23, but a major propellant leak that evening forced a postponement to the next day. 
     On the orders of the State Commission, all repairs to the missile were carried out in a fully fueled state, creating a remarkably dangerous situation at the pad. The repairs were successfully completed through the night, and all prelaunch operations proceeded as planned, until thirty minutes prior to the set launch time on October 24. At this point, there were still approximately 200 officers, engineers and soldiers near the pad, including Marshal Nedelin, the Strategic Missile Forces Commander-in-Chief, who scoffed at suggestions that he leave the pad area. "What's there to be afraid of? Am I not an officer?," he was reported to have asked. 
      But suddenly, the missile exploded on the pad, releasing an expanding inferno of destruction around the pad area. Within seconds, the rocket broke in half and fell on the pad, crushing any one who might have still been left alive. At that point, the fire and the heat increased in intensity as all the propellants ignited in a crescendo. Some people were simply engulfed in the fire, while others who managed to run in a burning state succumbed to the toxic gases withing minutes. 
     Technicians remained hanging from their harness from special cranes as their bodies burned. As the temperature raged to around 3,000 degrees, people just simply melted in the firestorm, many being reduced to ashes, Nedelin himself was identified only by his Gold Star medal attached to his uniform. All told, 126 individuals died in the blast, including senior military officials, deputy chief designers and numerous soldiers. The entire incident was kept under tight wraps, and Marshal Nedelin was said to have died in an aircraft accident, a piece of fiction that the Soviets officially maintained until early 1989.
     Investigation revealed that the failure had occurred when the second stage of the R-16 had spuriously started firing on the pad because of a control system failure, thus igniting the propellants in the first stage.

(Artwork: Robert Giguère)
Launch: 1st December 1960 at 7h26 UTC, from Baykonur Cosmodrome's LC-1, by an A-1/"Vostok" (8K72 L1-13).
Orbit: 180 km x 249 km x 64.95°
Destroyed: 2 December 1960
Mission: The fourth Vostok 1 spacecraft, called the Third Korabl-Sputnik in the Soviet press, was identical to the ship launched in August, save for the omission of the infrared orientation system that had been the source of so many problems on the previous missions. The spacecraft was launched without incident and placed into an orbit exactly mimicking the one planned at the time for an actual piloted mission. Aboard were two dogs, Pchelka and Mushka. Total mass in orbit was 4,563 kilograms. There was apparently improved biomedical instrumentation on board, as well as a different set of instruments for cosmic and radiation studies.
     The flight went well, and there were twelve successful communications sessions for telemetry reception. After about twenty-four hours in orbit, on the seventeenth orbit, the main TDU-1 engine was to fire to initiate reentry. Unfortunately, there was a malfunction in the stabilization system of the engine; the resulting firing was far shorter than had been planned. Although the spacecraft would still reenter, computations showed that the landing would overshoot Soviet territory. The spacecraft made one and a half more orbits, after which the descent apparatus with the dogs separated from the rest of the vehicle. 
     At this point, a special and unusual system was called into operation, one that was installed to address this precise situation: given the extreme secrecy and xenophobia of the missile and space programs, the only option for designers was to install a self-destruct system aboard the vehicle to destroy the "evidence" before recovery by non-Soviet parties. (Mercifully, such a system was only earmarked for the Vostok precursor missions and not for any actual piloted craft.) In the case of Korabl-Sputnik 3, the system went into operation at the beginning of reentry and destroyed the spacecraft along with its hapless passengers. At the time, the Soviet press merely announced that because of the incorrect attitude, the descent apparatus had burned up on reentry.

Launch: 15 December 1960 at 9h10 UTC, from Cape Canaveral Air Force Station's LC-12, by an Atlas Able (Atlas D 91D / Able-5).
Orbit: None.
Mission: This was third and last attempt by NASA to launch a probe to orbit the Moon in the 1959-60 period. Able VB mission, as with Pioneer 5 and Pioneer P-30, was to enter lunar orbit. Scientific objectives included studying radiation near the Moon, recording the incidence of micrometeoroids and detecting a lunar magnetic field. Planned lunar orbital parameters were 4,300 x 2,400 kilometers with a period of 9 to 10 hours. The spacecraft had a slightly different scientific instrument complement from that of its predecessors. Unfortunately, the Atlas-Able booster exploded 68 seconds after launch at an altitude of about 12.2 kilometers. Later investigation indicated that the cause was premature Able stage ignition while the first stage was still firing.

Launch: 22 December 1960, from Baykonur Cosmodrome's LC-1, by an A-1/"Vostok" (8K72K).
Orbit: None
Recovered: 22+ December 1960
Mission: The fifth Vostok 1 spacecraft was identical to the ship launched three weeks earlier, except for some minor modifications of the TDU-1 braking engine. Also, there was a slightly change in the booster-spacecraft stack: all earlier Korabl-Sputnik missions had used the 8K72 launch vehicle, but this flight would be the first to use a slightly modified variant designated the 8K72K, which substituted the RD-0109 (just over five and a half tons) for the RD-0105 (just over five tons) as the third orbital insertion stage. The nominally increased thrust wouid allow a slightly higher mass planned for the piloted variant. 
     At launch, the first two stages of the 8K72K booster performed without fault, but the new third stage engine prematurely cut off at 425 seconds into the lift off because of the destruction of the gas generator in the engine. The emergency escape system went into operation, and the spacecraft successfully separated as its flight trajectory described an arc across the Soviet Union. The payload reached an altitude of 214 kilometers and landed about 3,500 kilometers downrange from the launch site in one of the most remote and inaccessible areas of Siberia, in the region of the Podkamennaya Tunguska River close to the impact point of the famed Tunguska meteorite. 
     By the late hours of December 22, rescue forces began to detect signals from the descent apparatus and a search party was dispatched to try and locate the capsule. The rescue mission turned out to be one of the most harrowing episodes of the time. Once the rescue group was dropped at the general area of the landing site two days late on December 24, but they found themselves in waist-deep snow. By having aircraft fly in the direction of the object, they managed to reach the capsule. Once the team found the spacecraft, they had to approach it with extreme care because the emergency explosive system was to automatically detonate the vehicle sixty hours after landing. By the time they reached the spacecraft, it had already been sixty hours, but the capsule had still not exploded, forcing them to disengage the explosive in minus-forty-degree Centigrade temperatures. They later discovered that the cabling in the explosive system had burned through, neutralizing the bomb. Although both hatches on the descent apparatus had been discarded, the ejection seat had remained within the spherical capsule instead of ejecting out with the dogs. (Later investigation showed that during ejection, the seat had slammed into the side of the exit porthole and remained within the spacecraft.) The dogs were finally taken out of the capsule, a little cold but alive, and flown to safety, arriving in Moscow on December 26. 
     Bringing the descent apparatus itself back to Moscow proved to be much more difficult as they used a variety of strategies to literally drag the capsule through kilometers of snow. At one point, the recovery team had to terminate all rescue operations and spend the night in the middle of the ice and snow when the temperature dropped to minus sixty-two degrees Centigrade. It was the first week of January 1961 before the vehicle finally arrived in Moscow.
     An analysis of the launch abort showed that there were a number of major anomalies on the mission. Following the booster third-stage failure, the Vostok 1 craft was to separate into its component descent apparatus and instrument section modules. This never happened. The two capsules severed their connections only because of the thermal heating on reentering the atmosphere. Furthermore, the ejection seat was to have shot out of the capsule two and a half seconds after the hatch was jettisoned: on this mission, both events occurred simultaneously, causing the craft to deform from the shock of the failed ejection. Then there was the fortuitous failure in the self-destruct system.
