Lexington, Massachusetts high school student, Judith Miles, discusses her proposed Skylab experiment with Keith Demorest (right) and Henry Floyd, both of Marshall Space Flight Center (MSFC). In her experiment, called the “Web Formation in Zero Gravity”, called for spiders to be released into a box and their actions recorded to determine how well they adapt to the absence of gravity. Spiders are known to adapt quickly to other changes in the environment but nothing was known of their ability to adapt to weightlessness. At the same time spiders were weaving webs in Earth orbit, similar spiders were spinning webs in identical boxes on Earth under full gravity conditions. Miles was among the 25 winners of a contest in which some 3,500 high school students proposed experiments for the following year’s Skylab Mission. Of the 25 students, 6 did not see their experiments conducted on Skylab because the experiments were not compatible with Skylab hardware and timelines. Of the 19 remaining, 11 experiments required the manufacture of equipment.

Dr. von Braun inside the KC-135 in flight. The KC-135 provide NASA's Reduced-Gravity Program the unique weightlessness or zero-g environment of space flight for testing and training of human and hardware reactions. The recent version, KC-135A, is a specially modified turbojet transport which flies parabolic arcs to produce weightlessness periods of 20 to 25 seconds and its cargo bay test area is approximately 60 feet long, 10 feet wide, and 7 feet high.

A technician prepares a test sample in the Zero Gravity Research Facility clean room at the National Aeronautics and Space Administration (NASA) Lewis Research Center. The Zero Gravity Research Facility contained a drop tower which provided five seconds of microgravity during freefall in its 450-foot deep vacuum chamber. The facility has been used for a variety of studies relating to the behavior of fluids and flames in microgravity. During normal operations, a cylindrical 3-foot diameter and 11-foot long vehicle was used to house the experiments, instrumentation, and high speed cameras. The 4.5-foot long and 1.5-foot wide rectangular vehicle, seen in this photograph, was used less frequently. A 3-foot diameter orb was used for the special ten-second drops in which the package was pneumatically shot to the top of the tower then dropped. The facility also contained a control room, shop offices, tool and equipment rooms, and this clean room. The 242.5-foot long and 19.5-foot wide clean room was equipped with specialized cleaning equipment. In the 1960s the room was rated as a class 10,000 clean room, but I was capable of meeting the class 100 requirements. The room included a fume hood, ultrasonic cleaner, and a laminar flow station which operated as a class 100 environment. The environment in the clean room was maintained at 71° F and a relative humidity of 45- percent.

AS17-162-24053 (7-19 Dec. 1972) --- Scientist-astronaut Harrison H. "Jack" Schmitt, lunar module pilot, took this photograph of his two fellow crew men under zero-gravity conditions aboard the Apollo 17 spacecraft during the final lunar landing mission in NASA's Apollo program. That is astronaut Eugene A. Cernan, commander, who is seemingly "right side up." Astronaut Ronald E. Evans, command module pilot, appears to be "upside down." While astronauts Cernan and Schmitt descended in the Lunar Module (LM) "Challenger" to explore the Taurus-Littrow region of the moon, astronaut Evans remained with the Command and Service Modules (CSM) "America" in lunar orbit.

S69-39269 (10 July 1969) --- Astronaut Edwin E. Aldrin Jr., lunar module pilot of the Apollo 11 lunar landing mission, undergoes zero-gravity training aboard a U.S. Air Force KC-135 jet aircraft from nearby Patrick Air Force Base, Florida. Aldrin is wearing an Extravehicular Mobility Unit (EMU), the type of equipment which he will wear on the lunar surface.

Rockford, Illinois high school student, Vincent Converse, discussed his proposed Skylab experiment with Dr. Robert Head (right) and Gene Greshman of Marshall Space Flight Center (MSFC). His experiment, “Zero Gravity Mass Measurement” used a simple leaf spring with the mass to be weighed attached to the end. The electronic package oscillated the spring at a specific rate and the results were recorded electronically. Converse was among 25 winners of a contest in which some 3,500 high school students proposed experiments for the following year’s Skylab mission. Of the 25 students, 6 did not see their experiments conducted on Skylab because the experiments were not compatible with Skylab hardware and timelines. Of the 19 remaining, 11 experiments required the manufacture of equipment, such as that of Converse’s experiment.

Aldrin Jr., Apollo 11 lunar module pilot, performs for his Earth-bound television audience, in this color reproduction taken from a TV transmission, from the Apollo 11 spacecraft during its trans-Earth journey home from the moon. Aldrin illustrates how to make a sandwich under zero-gravity conditions. When this picture was made, Apollo 11 was approximately 137,000 nautical miles from Earth, traveling at a speed of about 4,300 feet per second. Also, aboard the spacecraft were astronauts Neil A. Armstrong, commander; and Michael Collins, command module pilot.

S79-30347 (31 March 1979) --- Taking advantage of a brief period of zero-gravity afforded aboard a KC-135 flying a parabolic curve, the flight crew of the first space shuttle orbital flight test (STS-1) goes through a spacesuit donning exercise. Astronaut John W. Young has just entered the hard-material torso of the shuttle spacesuit by approaching it from below. He is assisted by astronaut Robert L. Crippen. The torso is held in place by a special stand here, simulating the function provided by the airlock wall aboard the actual shuttle craft. The life support system is mated to the torso on Earth and remains so during the flight, requiring this type of donning and doffing exercise. Note Crippen?s suit is the type to be used for intravehicular activity in the shirt sleeve environment to be afforded aboard shuttle. The suit worn by Young is for extravehicular activity (EVA). Young will be STS-1 commander and Crippen, pilot. They will man the space shuttle orbiter 102 Columbia. Photo credit: NASA

Miss Cheryl Peltz, high school student from Littleton, Colorado, discusses her “Cytoplasmic Streaming in Zero Gravity” experiment with Ed Armstrong (left) of the NASA Manned Spacecraft Center, and her advisor Charles Cothran (right) of the NASA Marshall Space Flight Center (MSFC). She was one of the 25 winners of a contest in which some 3,500 high school students proposed experiments for the following year’s Skylab Mission. Of the 25 students, 6 did not see their experiments conducted on Skylab because the experiments were not compatible with Skylab hardware and timelines. Of the 19 remaining, 11 experiments required the manufacture of equipment, of which Miss Peltz’s was one.

S86-25196 (January 1986) --- Sharon Christa McAuliffe, STS-51L citizen observer/payload specialist, gets a preview of microgravity during a special flight aboard NASA?s KC-135 ?zero gravity? aircraft.

National Aeronautics and Space Administration (NASA) Lewis Research Center. Lewis researchers had been studying the behavior of liquid in microgravity for several years using ballistic rocket flights, aircraft flying series of parabolas, and in the 2.2-Second Drop Tower. It was easier to control experiments and repeat tests based on almost instantaneous test results in the Zero Gravity Research Facility than missiles or aircraft. It also more than doubled the microgravity time of the original drop tower. The experiments were enclosed in a large experiment package that was suspended inside the chamber. A vacuum was introduced to the chamber before the package was released. The test equipment allowed researchers to film and take measurements of the experiment as it was falling. The 2500‐pound package was slowed by special Styrofoam‐like pellets in a decelerator cart. An experiment, traveling 176 feet per second, was stopped in about 15 feet of deceleration material. The facility’s designers struggled to determine the correct type of deceleration pellets to use. For several years Lewis engineers tested various samples from manufacturers. The final selection was not made until the facility’s completion in May 1966, just before the facility made its public debut at the 1966 Inspection of the Center.

A rectangular drop test vehicle perched above 450-foot shaft at the Zero Gravity Research Facility at NASA Lewis Research Center. The drop tower was designed to provide five seconds of microgravity during a normal drop, but had a pneumatic gun that could quickly propel the vehicle to the top of the shaft prior to its drop, thus providing ten seconds of microgravity. The shaft contained a steel-lined vacuum chamber 20 feet in diameter and 469 feet deep. The package was stopped at the bottom of the pit by a 15-foot deep deceleration cart filled with polystyrene pellets. During normal operations, a cylindrical 3-foot diameter and 11-foot long vehicle was used to house the experiments, instrumentation, and high speed cameras. The 4.5-foot long and 1.5-foot wide rectangular vehicle, seen in this photograph, was used less frequently. A 3-foot diameter orb was used for the ten second drops. After the test vehicle was prepared it was suspended above the shaft from the top of the chamber. A lid was used to seal the top of the chamber. The vacuum system reduced the pressure levels inside the chamber. The bolt holding the vehicle was then sheared and the vehicle plummeted into the deceleration cart.

SL3-108-1307 (July-September 1973) --- A close-up view of Arabella, one of the two Skylab 3 common cross spiders "Araneus diadematus," and the web it had spun in the zero-gravity of space aboard the Skylab space station cluster in Earth orbit. This picture was taken with a hand-held 35mm Nikon camera. During the 59-day Skylab 3 mission the two spiders, Arabella and Anita, were housed in an enclosure onto which a motion picture and a still camera were attempts to build a web in the weightless environment. The spider experiment (ED52) was one of 25 experiments selected for Skylab by NASA from more than 3,400 experiment proposals submitted by high school students throughout the nation. ED52 was submitted by 17-year-old Judith S. Miles of Lexington, Massachusetts. Anita died during the last week of the mission. Photo credit: NASA

KENNEDY SPACE CENTER, FLA. -- At the Kennedy Space Center Shuttle Landing Facility, noted physicist Stephen Hawking, in the wheelchair, arrives at the runway for his first zero-gravity flight. The flight will be aboard a modified Boeing 727 aircraft owned by Zero Gravity Corp., a commercial company licensed to provide the public with weightless flight experiences. At left is Peter Diamandis, founder of the Zero Gravity Corp. Behind Hawking is Nicola O'Brien, a nurse practitioner who is Hawking's aide. Hawking developed amyotrophic lateral sclerosis disease in the 1960s, a type of motor neuron disease which would cost him the loss of almost all neuromuscular control.
