Man will conquer space soon

Collier's, March 22, 1952Collier’s Magazine publishes an extensive pictorial article with text by space pioneers Wernher von Braun and Willy Ley, and illustrations by Chesley Bonestell, positing a future with plane-like spacecraft making routine trips to orbiting space stations. The article suggests that the station could be a reality in ten years and “twice the cost of the atom bomb” if the public shows its support for space exploration. Though spaceplanes and stations are more than a decade away, the Collier’s article is a seminal moment in the space age.

Project Mercury

MercuryThe newly-formed NASA reveals a bold plan: Project Mercury will be an extensive program to create a vehicle capable of safely sending men into Earth orbit and returning them in one piece. The rigorous selection process to find the country’s first space pilots – astronauts – begins, focusing on combat pilots and especially test pilots with experience in flying unproven experimental aircraft (the Mercury spacecraft will definitely qualify for this description).

Mercury 2: canned Ham

HamThe first living creature to reach space aboard an American rocket is Ham, a chimpanzee wired with electrodes and sensors to determine the effects of space travel on a higher primate whose body might react similarly to that of a human being. NASA sends Ham on the sixteen-minute suborbital Mercury 2 flight, ending in a splashdown in the Atlantic. Both Ham and his vehicle survive the flight despite numerous equipment glitches in both the Redstone rocket and the Mercury capsule itself (which actually blasts away from the Redstone via its launch abort system), which loses cabin pressure (fortunately, Ham has his own spacesuit to protect him) and then puts its primate pilot through a punishing 17G reentry. For his pioneering feat of spaceflight, Ham receives an apple, an orange, and paid retirement to the National Zoo.

Mercury 4: a sinking feeling

Gus GrissomThe second American in space is Virgil “Gus” Grissom, pilot of the Mercury 4 capsule Liberty Bell 7. Like Alan Shepard’s flight, Grissom’s launch reaches an altitute of 118 miles and splashes down 15 minutes later, but mechanical problems with the explosive bolts to release the capsule’s hatch allow water into the vehicle. Grissom has to bail out at sea, wearing a spacesuit that’s rapidly taking on water, while Liberty Bell 7 sinks to the bottom of the Atlantic. Grissom weathers repeated accusations that he manually blew the hatch and caused his vehicle to sink, a claim which is later disproven.

Vostok 2

Vostok 2The Soviet Union launches its second manned spacecraft, Vostok 2, with cosmonaut Gherman Titov aboard. This mission sets a new space endurance record, with Titov spending just over one day in orbit, circling Earth 17 times in the process. Later accounts show that it’s not a pleasant day in orbit: Titov is reportedly the first sufferer of space sickness, vomiting in the cabin of his Vostok capsule.

Saturn I

Saturn IAn unmanned Saturn I rocket is launched, the first practical demonstration of the multiple-engine design which has already been earmarked for future Apollo missions to the moon. Designed by expatriate German rocket engineer Werhner von Braun, the Saturn I is the first iteration of a family of heavy-lift rockets that will include the Saturn IB and the Saturn V; in this configuration, the Saturn I is the first stage of a Saturn V with no second stage.

Mercury 5: first American monkey in orbit

Enos!Prior to putting an astronaut in orbit, NASA launches a chimpanzee named Enos on a two-orbit Mercury flight to validate the survivability of the spacecraft for an extended flight. Enos is recalled to Earth when both his spacesuit and his Mercury capsule begins heating up unexpectedly, and attitude control is lost; after three hours and two orbits, Mercury 5 returns to Earth. While hauling the capsule from the ocean, recovery crews accidentally crack the window. Despite all this, Enos is safely returned home; he dies a year later from an illness not related to his orbital flight.

Apollo unveiled

ApolloWeeks before an American astronaut first makes it to orbit, NASA unveils the design of the two Apollo spacecraft: a command/service module (large compared to the Mercury capsules Americans have already seen) and a completely un-aerodynamic lunar module whose unique shape, designed solely for landing on the moon, will never need to operate inside an atmosphere. Though further refinements in both designs are still to come, NASA has already decided on the basic shape of its crash lunar exploration program whose goal is to land a man on the moon before 1970.

Mercury 6: first American in orbit

John GlennThe third manned Mercury flight, Friendship 7, puts John Glenn in orbit for nearly five hours, the first American astronaut to circle the Earth. The retro-rocket package on Glenn’s vehicle, Friendship 7, becomes an issue when a sensor indicates that the heat shield protecting the capsule’s interior from the intense heat of reentry has slipped. Intended to be cast off before reentry, the retro package is left on at the insistence of ground controllers, resulting in an unusually rough ride home after only three orbits.

Mercury 7

Mercury 7The second American orbital flight is launched, with Scott Carpenter lifting off aboard Mercury 7 (nicknamed Aurora 7). Carpenter’s five-hour, three-orbit mission is almost a carbon copy of John Glenn’s orbital flight, the primary goal being to duplicate the flight and compare the two astronauts’ reports and reactions.

Vostok 4

Vostok 4The Soviet Union launches Vostok 4 with Pavel Popovich aboard, while Andrian Nikolayev orbits overhead in Vostok 3. The two vehicles pass within four miles of one another, but with no precision maneuvering, rendezvous or docking equipment, there’s little practical engineering value in the tandem space flight, other than to prove that ground controllers can handle two simultaneous flights. Popovich returns to Earth after nearly three days.

Mercury 9

Mercury 9The final manned Mercury flight, Mercury 9 (nicknamed Faith 7) puts astronaut Gordon Cooper in orbit for over a day. Over the course of 34 hours, Cooper circles Earth 22 times, performing small-scale experiments and photography tasks. With Mercury astronaut Deke Slayton grounded due to health issues, only six of the Mercury seven have flown. Development of a two-seater descendant of the Mercury design (initially called “Big Mercury” but now known as Gemini) is well underway, along with the development of the Apollo spacecraft that will succeed Gemini and take men to the moon. Cooper is the last solo American space pilot until Mike Melvill flies the experimental SpaceShip One into suborbital space in the 21st century.

Vostok 5

Valery BykovskyThe Soviet Union launches the Vostok 5 mission to orbit Earth, carrying cosmonaut Valery Bykovsky aboard. He remains in orbit for over four days, traveling over 2,000,000 miles in Earth orbit. As he flies over the Soviet Union, a second Vostok capsule is launched in the USSR’s first bid to trump the United States by mounting the first manned space rendezvous.

Vostok 6: first woman in space

Valentina TereshkovaWhile cosmonaut Valery Bykovsky orbits overhead about Vostok 5, Vostok 6 is launched from the Soviet Union, carrying the first female space traveler, cosmonaut Valentina Tereshkova. Spending nearly three days in orbit, Tereshkova’s Vostok capsule serves as a rendezvous target for Vostok 5, though without precision piloting ability, the two vehicles’ closest approach is no closer than within three miles, and neither Vostok is actually equipped for any kind of docking. Tereshkova’s flight is a political point scored for the Soviet Union, but only a brief victory for womankind: it will be two more decades before another woman flies in space. The glass ceiling remains firmly in orbit.

The Vehicle Assembly Building

Vehicle Assembly BuildingConstruction commences on NASA’s massive Vehicle Assembly Building (originally named the Vertical Assembly Building), where the giant Saturn V rockets for Apollo lunar missions will be constructed, tested, and then rolled out to the launch pad atop huge mobile crawlers. Covering eight acres of land on Merritt Island, Florida, the building must withstand Florida’s notorious hurricane seasons (and protect any rockets under construction within) as well as the shockwaves of Saturn V rocket launches taking place only three miles away; special ventilation and humidity control systems have to be built as well, as the interior space is so voluminous that the building has its own internal weather! The VAB will later transition to the assembly of the Space Shuttle launch system elements and the Space Launch System boosters for the 21st century Orion program.

Manned Orbiting Laboratory

MOLThe Air Force announces the Manned Orbiting Laboratory project, a joint venture with NASA to orbit a space station using modified Gemini capsules to launch specially selected Air Force crews for month-long stays in orbit. What isn’t revealed – but isn’t too hard to figure out – is that MOL’s mission is largely military, including orbital reconaissance: the station will essentially be a manned spy satellite. The Soviet Union responds by beginning to draw up plans for its own manned military space station, Almaz.

Voskhod 1: three men in space

Voskhod 1The Soviet Union launches the first of its next-generation manned spacecraft, the roomier Voskhod 1 capsule. Cosmonauts Dr. Boris Yegorov, Dr. Konstantin Feoktistov and Vladimir Komarov become the first three-man crew in space, though they find that the larger vehicle is still cramped for a crew of that size; the tight fit makes no allowances for spacesuits, which also makes the Voskhod 1 crew the first “shirtsleeves” space flight. Voskhod 1 spends just over one day in orbit before reentering the atmosphere; for the first time, the crew lands inside the capsule, rather than ejecting and parachuting down after reentry.

Voskhod 2: the first spacewalk

Voskhod 2Voskhod 2 is launched by the Soviet Union, this time with only a two-man crew for a very specific mission. Cosmonauts Pavel Belyaev and Alexei Leonov orbit Earth for 28 hours, but during one orbit an airlock is extended from the side of their Voskhod capsule and Leonov squeezes through the airlock tunnel in a spacesuit, becoming the first human being to exit his spacecraft in flight. He spends 10 minutes walking in space, but this Soviet space first nearly ends badly; Leonov’s suit “inflates” as a result of pressurization, making it extremely difficult to enter the vehicle again (and nearly overexerting him in the process of getting back inside). A guidance system malfunction forces Belyaev to manually control the vehicle during reentry and descent, but Voskhod 2’s crew capsule lands over 700 miles away from Moscow in a remote wilderness in the dead of winter, and the cosmonauts wait hours for a recovery team to rescue them via helicopter.

Gemini 3

Gemini 3The first two-man American space crew lifts off in the first manned flight of NASA’s Gemini program. With a larger, more maneuverable spacecraft designed for longer stays in space, Gemini is intended to be a stepping stone on the path to the first lunar landing, allowing astronauts to practice rendezvous, docking, and orbital changes. Aboard the Gemini capsule are Mercury veteran Gus Grissom and rookie John Young; the capsule is unofficially nicknamed “Molly Brown” (a reference to Grissom’s sunken Mercury capsule). The flight lasts barely five hours and includes the first-ever orbital attitude changed made by a manned spacecraft.

Vehicle Assembly Building open for business

Vehicle Assembly BuildingNASA’s massive Vehicle Assembly Building is completed at the spaceport rapidly taking shape on Cape Canaveral ahead of the Apollo lunar missions. Topped off at a total cost of $117,000,000, the VAB is where Saturn V rockets are assembled for the Apollo moonshots, and the huge, eight-acre building will later transition to the assembly of the Space Shuttle launch system elements and the Space Launch System boosters for the 21st century Orion program.

Gemini 4

Gemini 4The second manned Gemini flight, Gemini 4, lifts off with Jim McDivitt and Ed White aboard for a four-day mission. Four hours into the flight, White becomes the first American spacewalker, controlling his movement with a handheld device with small jets allowing him to change his own orientation, though he is tethered to the Gemini capsule at all times. This is the first NASA flight overseen from the new Manned Space Center constructed in Houston, Texas, and the first to be broadcast live worldwide.

Gemini 5

Gemini 5Gemini 5 lifts off on the first manned spaceflight to last over a week, breaking the previous record held by the Soviet crew of Vostok 5; the eight-day flight is crucial in proving that humans could function for the minimum amount of time that a flight to the moon and back again would take. Instead of short-lived batteries, Gemini 5 is the first American spacecraft powered by fuel cells, another important step toward longer flights to the moon. The crew consists of Gordon Cooper and Pete Conrad.

Gemini 7

Gemini 7Gemini 7 is launched with Frank Borman and Jim Lovell aboard, on a grueling two-week endurance mission which also sees the first manned space rendezvous. The 14-day flight sets a new space endurance record that stands for five years – none of the lunar landing missions will last that long – and the astronauts function well throughout the flight, though some of Gemini 7’s systems begin to fray at the edges toward the end of the mission. Eleven days into Gemini 7’s flight, Gemini 6 is launched on a one-day mission to act as the rendezvous target, and the two manned vehicles close to within mere feet of each other – a first for human spaceflight.

Gemini 6

Gemini 6Delayed from its original launch date in October, Gemini 6 had been intended to be the first American space docking mission. An unmanned Agena rocket, launched ahead of Gemini 6 to serve as its docking target, had exploded during liftoff, and the October Gemini 6 mission had been scrubbed as a result. Instead, the crew of Gemini 6 – Wally Schirra and Thomas Stafford – are launched on a one-day mission to become the rendezvous target for the already-launched Gemini 7. The two manned vehicles close to within mere feet of each other – a first for human spaceflight.

Gemini 8: spinning out of control

Gemini 8Gemini 8, carrying David Scott and Neil Armstrong, lifts off on a mission to fulfill the Agena booster rendezvous and docking goal originally assigned to Gemini 6. After docking with the Agena vehicle a few hours into the flight, Gemini 8 begins an unplanned, uncontrolled roll, and the crew initially believe it to be an issue with the Agena. But after undocking from the Agena, the Gemini capsule spins even faster out of control until Armstrong, using maneuvering thrusters reserved for reentry, cancels out the roll. Mission rules require an immediate return to Earth, and the astronauts splash down safely, barely 11 hours after liftoff.

Gemini 9

Gemini 9Gemini 9 lifts off on a three-day mission to complete the still unfulfilled docking objectives of the Gemini program. The flight has already seen significant problems, not the least of which is the death of the originally-assigned crew, Elliott See and Charles Bassett, in an accident involving T-38 training jets. The backup crew, Thomas Stafford and Gene Cernan, fly Gemini 9 instead, but find that their rendezvous/docking target is still trapped in the aerodynamic shroud that protected it during launch (the shroud would normally have been jettisoned). Furthermore, a spacewalk has been written into the mission plan, requiring Cernan to leave Gemini and go to the rear of the vehicle to unstow and test a “jetpack” (an early prototype of the Manned Maneuvering Unit that will finally see use in the space shuttle program in the 1980s). The spacewalk becomes a two-hour ordeal which leaves Cernan exhausted, thanks to the lack of handholds on the exterior of the Gemini capsule. The flight ends after three days in space.

Gemini 10

Gemini 10With the docking and EVA goals of the Gemini program still unmet, and with the first Apollo missions looming ahead in the mission schedule, Gemini 10 lifts off with a lot riding on it (in addition to astronauts John Young and Michael Collins). Over the course of nearly three days, the Gemini 10 crew makes up for lost time, successfully docking with an Agena booster and changing the vehicle’s orbital altitude to 188 miles – a new distance-from-Earth record for a manned spacecraft. Collins conducts two spacewalks, but the lack of handgrips on the exterior of the Gemini capsule frustrates his efforts. Gemini 10 returns after three days in space.

Gemini 11

Gemini 11Gemini 11 lifts off on a three-day mission to continue validating rendezvous, docking and spacewalking techniques that will be needed on the upcoming Apollo lunar missions. With Pete Conrad and Dick Gordon aboard, Gemini 11 becomes the furthest manned object from Earth, using an Agena booster to push itself into a higher orbit that takes Gemini 850 miles away from Earth at its furthest point. After three days of docking, spacewalks and orbit-changing exercises, Gemini 11 returns to Earth.

Gemini 12

Gemini 12The final mission of NASA’s Gemini program, Gemini 12 lifts off with Jim Lovell and “Buzz” Aldrin aboard. Over their three-day flight, the last two-man American astronaut crew until the early Space Shuttle flights finally demonstrates improved spacewalk techniques, with handholds having been added to the Gemini capsule’s exterior, and pre-launch training conducted underwater in weighted spacesuits. Aldrin performs a two-hour spacewalk without overexerting himself, a first for the American space program. Gemini 12 splashes down, having accomplished all of the Gemini program goals mere weeks ahead of the first launch window for Apollo 1.

Apollo 1

Crew of Apollo 1During a ground test of the Apollo 1 spacecraft, a fire breaks out in the 100% oxygen atmosphere of the Apollo capsule, leaving the crew – Virgil “Gus” Grissom, Ed White and Roger Chaffee – unable to operate or open the hatch. The searing heat burns through their oxygen hoses, suffocating the three astronauts in short order. Months of investigations and accusations follow, leading to changes of management at both NASA and North American Aviation, the aerospace company contracted to build the Apollo command/service module. Extensive redesign of the Apollo vehicle follows, including a switch to a nitrogen/oxygen atmosphere and a complete rethink of the hatch, and manned flights won’t resume until late 1968.

This event is dramatized in the Apollo One episode of HBO’s 1998 series From The Earth To The Moon.

Soyuz 1

Vladimir KomarovThe first flight of the Soviet Union’s new manned space vehicle, Soyuz 1, lifts off from the Baikonur Cosmodrome. Though designed to accomodate a crew of three – and intended to be the answer to NASA’s Apollo command/service module in the ongoing race to reach the moon – the first Soyuz is flown by test pilot (and close friend of Yuri Gagarin) Vladimir Komarov. Though early plans for the mission involve a rendezvous and docking with a second Soyuz, only one vehicle is available for the mission, and it suffers a series of technical problems. Though aware of the faults in the Soyuz design, engineers have been pressured to put a manned Soyuz in orbit for political reasons.

Soyuz 1: cosmonaut down

Soyuz 1After a day in space aboard a spacecraft crawling with technical glitches, cosmonaut Vladimir Komarov orients the Soyuz 1 capsule for return to Earth. Though the vehicle survives reentry through Earth’s atmosphere, the main parachute fails to open, and the first Soyuz capsule returns to Earth at a speed of well over 100 miles per hour, killing Komarov instantly. The Soviet Union’s space program is stalled – much like the American Apollo program, postponed after the fatal Apollo 1 fire – well into 1968 as a result of the need to redesign Soyuz from the inside out.

Apollo 4: Saturn V’s first flight

Apollo 4As questions over the safety of the Apollo spacecraft continue to rage, NASA performs the first “all-up” test of the Saturn V rocket with an unmanned launch officially designated Apollo 4. Unsure of what to expect, onlookers and press are stunned by the roar of the five huge F-1 engines; the vibrations case CBS news anchor Walter Cronkite’s broadcast booth to partially collapse while he’s on the air – over three miles away. The entire vehicle performs flawlessly, propelling the empty (but active) Apollo command/service module to a distance of 10,000 miles before commanding it to return to Earth, simulating the speed and return angle of a vehicle returning from the moon.

Apollo 7

Apollo 7After a year of redesign and reorganization, NASA resumes manned flights with Apollo 7, the first of the successful Apollo flights. An 11-day Earth-orbit shakedown cruise for the Apollo command/service module, the mission becomes contentious when the three-man crew – Wally Schirra, Walt Cunningham and Donn Eisele – is loaded down with a jam-packed mission plan. Worse, Schirra comes down with a cold which quickly spreads to his crewmates in the enclosed biosphere of the Apollo command module. The flight’s technical goals are met with flying colors, though the crew’s snippy responses to ground controllers keep them off the crew rotation for future Apollo flights.

This mission is dramatized in the We Have Cleared The Tower episode of HBO’s 1998 series From The Earth To The Moon.

Soyuz 3

Soyuz 3The Soviet Union resumes its manned space program with the launch of cosmonaut Georgy Beregovoy aboard the redesigned Soyuz 3 vehicle. The unmanned Soyuz 2 is launched the day before to serve as a docking target for Soyuz 3, but while the two vehicles pass close to each other, no docking is achieved. Beregovoy successfully returns to Earth – the first Soyuz cosmonaut to do so – after four days in orbit.

Apollo 8

Apollo 8Moved ahead in the schedule due to ongoing difficulties with the construction of the lunar module, Apollo 8 lifts off from Cape Canaveral on a mission that represents NASA’s biggest gamble yet in the race for the moon: on only the second manned Apollo flight, astronauts Frank Borman, Jim Lovell and Bill Anders will go to the moon, orbit it in their command/service module, and return to Earth (the lunar module is still in the late stages of development). Mission planners plot out a free return trajectory – ensuring that without engines, Apollo 8 could loop around behind the moon and swing back toward home.

This mission is dramatized in the 1968 episode of HBO’s 1998 series From The Earth To The Moon.
