On Jan. 17, 1990, NASA announced the selection of its 13th group of astronaut candidates. The diverse group comprised 23 candidates – seven pilots and 16 mission specialists. The group included one African American, one Asian American, and five women including the first female pilot and the first Hispanic woman. Following one year of astronaut candidate training, all 23 became eligible for technical assignments within the astronaut office and for assignment to space shuttle crews. All members of the group completed at least one spaceflight, making significant contributions to the space shuttle program, the Shuttle Mir program, important science missions, and assembly and maintenance of the International Space Station. Several went on to serve in key NASA management positions.

The newest class of NASA astronaut candidates included pilot candidates Kenneth Cockrell, Eileen Collins, William Gregory, James Halsell, Charles Precourt, Richard Searfoss, and Terrence Wilcutt and mission specialist candidates Daniel Bursch, Leroy Chiao, Rich Clifford, Bernard Harris, Susan Helms, Thomas Jones, William Mc Arthur, James Newman, Ellen Ochoa, Ronald Sega, Nancy Sherlock, Donald Thomas, Janice Voss, Carl Walz, Jeffrey Wisoff, and David Wolf. From the 1,945 qualified applicants, NASA invited 103 candidates for interviews and medical exams at NASA’s Johnson Space Center (JSC) in Houston between September and November 1989. 

The 23 astronaut candidates reported to work at JSC on July 16, 1990, to begin their one-year training period. During the yearlong training, the candidates attended classes in applied sciences, space shuttle systems, space medicine, Earth and planetary sciences, and materials sciences. They visited each of the NASA centers to learn about their functions and received instruction in flying the T-38 Talon training aircraft, high-altitude and ground egress systems, survival skills, parasail flight, and scuba. They experienced short-duration weightlessness aboard NASA’s KC-135 aircraft dubbed the Vomit Comet. After completing the astronaut candidate training, they qualified for various technical assignments within the astronaut office leading to assignments to space shuttle crews. 

Per tradition, most astronaut classes have a nickname, often humorously given to them by the previous class of astronauts. In the case of the class of 1990, they chose their own nickname, The Hairballs. The origin stems from the class adopting a black cat as their mascot, in recognition of their class number 13. The nickname came about as hairballs are often associated with cats. 

Daniel Bursch 

Born in Pennsylvania, Bursch grew up in New York state and graduated from the U.S. Naval Academy. He served as a pilot in the U.S. Navy prior to his selection as an astronaut. He received his first flight assignment as a mission specialist on STS-51, flying with fellow Hairballs Newman and Walz on the 10-day flight aboard Discovery in 1993. On his second mission, the 10-day STS-68 flight aboard Endeavour in 1994, Bursch, accompanied by fellow classmates Jones, Wilcutt, and Wisoff, served as a mission specialist on the Space Radar Laboratory-2 (SRL-2) Earth observation mission. For his third trip into space, Bursch flew as a mission specialist aboard Endeavour for the 10-day STS-77 mission in 1996. For his fourth and final spaceflight, Bursch, along with fellow Hairball Walz, spent 196 days in space as an Expedition 4 flight engineer aboard the space station in 2001 and 2002, conducting two spacewalks totaling 11 hours 46 minutes.

      This photomosaic of the Andromeda galaxy is the largest ever assembled from Hubble observations. Credits:
      NASA, ESA, Benjamin F. Williams (UWashington), Zhuo Chen (UWashington), L. Clifton Johnson (Northwestern); Image Processing: Joseph DePasquale (STScI) In the years following the launch of NASA’s Hubble Space Telescope, astronomers have tallied over 1 trillion galaxies in the universe. But only one galaxy stands out as the most important nearby stellar island to our Milky Way — the magnificent Andromeda galaxy (Messier 31). It can be seen with the naked eye on a very clear autumn night as a faint cigar-shaped object roughly the apparent angular diameter of our Moon.
      A century ago, Edwin Hubble first established that this so-called “spiral nebula” was actually very far outside our own Milky Way galaxy — at a distance of approximately 2.5 million light-years or roughly 25 Milky Way diameters. Prior to that, astronomers had long thought that the Milky way encompassed the entire universe. Overnight, Hubble’s discovery turned cosmology upside down by unveiling an infinitely grander universe.
      Now, a century later, the space telescope named for Hubble has accomplished the most comprehensive survey of this enticing empire of stars. The Hubble telescope is yielding new clues to the evolutionary history of Andromeda, and it looks markedly different from the Milky Way’s history.
      This is largest photomosaic ever assembled from Hubble Space Telescope observations. It is a panoramic view of the neighboring Andromeda galaxy, located 2.5 million light-years away. It took over 10 years to make this vast and colorful portrait of the galaxy, requiring over 600 Hubble overlapping snapshots that were challenging to stitch together. The galaxy is so close to us, that in angular size it is six times the apparent diameter of the full Moon, and can be seen with the unaided eye. For Hubble’s pinpoint view, that’s a lot of celestial real estate to cover. This stunning, colorful mosaic captures the glow of 200 million stars. That’s still a fraction of Andromeda’s population. And the stars are spread across about 2.5 billion pixels. The detailed look at the resolved stars will help astronomers piece together the galaxy’s past history that includes mergers with smaller satellite galaxies. NASA, ESA, Benjamin F.

      Without Andromeda as a proxy for spiral galaxies in the universe at large, astronomers would know much less about the structure and evolution of our own Milky Way. That’s because we are embedded inside the Milky Way. This is like trying to understand the layout of New York City by standing in the middle of Central Park.
      “With Hubble we can get into enormous detail about what’s happening on a holistic scale across the entire disk of the galaxy. You can’t do that with any other large galaxy,” said principal investigator Ben Williams of the University of Washington. Hubble’s sharp imaging capabilities can resolve more than 200 million stars in the Andromeda galaxy, detecting only stars brighter than our Sun. They look like grains of sand across the beach. But that’s just the tip of the iceberg. Andromeda’s total population is estimated to be 1 trillion stars, with many less massive stars falling below Hubble’s sensitivity limit.
      Photographing Andromeda was a herculean task because the galaxy is a much bigger target on the sky than the galaxies Hubble routinely observes, which are often billions of light-years away. The full mosaic was carried out under two Hubble programs. In total, it required over 1,000 Hubble orbits, spanning more than a decade.
      This panorama started with the Panchromatic Hubble Andromeda Treasury (PHAT) program about a decade ago. Images were obtained at near-ultraviolet, visible, and near-infrared wavelengths using the Advanced Camera for Surveys and the Wide Field Camera 3 aboard Hubble to photograph the northern half of Andromeda.
      This is the largest photomosaic ever made by the Hubble Space Telescope. The target is the vast Andromeda galaxy that is only 2.5 million light-years from Earth, making it the nearest galaxy to our own Milky Way. Andromeda is seen almost edge-on, tilted by 77 degrees relative to Earth’s view. The galaxy is so large that the mosaic is assembled from approximately 600 separate overlapping fields of view taken over 10 years of Hubble observing — a challenge to stitch together over such a large area. The mosaic image is made up of at least 2.5 billion pixels. Hubble resolves an estimated 200 million stars that are hotter than our Sun, but still a fraction of the galaxy’s total estimated stellar population. Interesting regions include: (a) Clusters of bright blue stars embedded within the galaxy, background galaxies seen much farther away, and photo-bombing by a couple bright foreground stars that are actually inside our Milky Way; (b) NGC 206 the most conspicuous star cloud in Andromeda; (c) A young cluster of blue newborn stars; (d) The satellite galaxy M32, that may be the residual core of a galaxy that once collided with Andromeda; (e) Dark dust lanes across myriad stars.

      This program was followed up by the Panchromatic Hubble Andromeda Southern Treasury (PHAST), recently published in The Astrophysical Journal and led by Zhuo Chen at the University of Washington, which added images of approximately 100 million stars in the southern half of Andromeda. This region is structurally unique and more sensitive to the galaxy’s merger history than the northern disk mapped by the PHAT survey.
      The combined programs collectively cover the entire disk of Andromeda, which is seen almost edge-on — tilted by 77 degrees relative to Earth’s view. The galaxy is so large that the mosaic is assembled from approximately 600 separate fields of view. The mosaic image is made up of at least 2.5 billion pixels.
      The complementary Hubble survey programs provide information about the age, heavy-element abundance, and stellar masses inside Andromeda. This will allow astronomers to distinguish between competing scenarios where Andromeda merged with one or more galaxies. Hubble’s detailed measurements constrain models of Andromeda’s merger history and disk evolution.
      A Galactic ‘Train Wreck’
      Though the Milky Way and Andromeda formed presumably around the same time many billions of years ago, observational evidence shows that they have very different evolutionary histories, despite growing up in the same cosmological neighborhood. Andromeda seems to be more highly populated with younger stars and unusual features like coherent streams of stars, say researchers. This implies it has a more active recent star-formation and interaction history than the Milky Way.
      “Andromeda’s a train wreck. It looks like it has been through some kind of event that caused it to form a lot of stars and then just shut down,” said Daniel Weisz at the University of California, Berkeley. “This was probably due to a collision with another galaxy in the neighborhood.”
      A possible culprit is the compact satellite galaxy Messier 32, which resembles the stripped-down core of a once-spiral galaxy that may have interacted with Andromeda in the past. Computer simulations suggest that when a close encounter with another galaxy uses up all the available interstellar gas, star formation subsides.
      The Andromeda Galaxy, our closest galactic neighbor, holds over 1 trillion stars and has been a key to unlocking the secrets of the universe. Thanks to NASA’s Hubble Space Telescope, we’re now seeing Andromeda in stunning new detail, revealing its dynamic history and unique structure.

      “Andromeda looks like a transitional type of galaxy that’s between a star-forming spiral and a sort of elliptical galaxy dominated by aging red stars,” said Weisz. “We can tell it’s got this big central bulge of older stars and a star-forming disk that’s not as active as you might expect given the galaxy’s mass.”
      “This detailed look at the resolved stars will help us to piece together the galaxy’s past merger and interaction history,” added Williams.
      Hubble’s new findings will support future observations by NASA’s James Webb Space Telescope and the upcoming Nancy Grace Roman Space Telescope. Essentially a wide-angle version of Hubble (with the same sized mirror), Roman will capture the equivalent of at least 100 high-resolution Hubble images in a single exposure. These observations will complement and extend Hubble’s huge dataset.
      The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

      50 Years Ago: Preparing the Final Saturn Rocket for Flight
      By NASA
      With the historic first international space docking mission only six months away, preparations on the ground for the Apollo-Soyuz Test Project (ASTP) intensified. At NASA’s Kennedy Space Center (KSC) in Florida, workers in the Vehicle Assembly Building (VAB) stacked the rocket for the mission, the final Saturn rocket assembled for flight. In the nearby Manned Spacecraft Operations Building (MSOB), the Apollo prime crew of Commander Thomas Stafford, Command Module Pilot Vance Brand, and Docking Module Pilot Donald “Deke” Slayton, and their backups Alan Bean, Ronald Evans, and Jack Lousma conducted vacuum chamber tests of the Command Module (CM), the final Apollo spacecraft prepared for flight.  

      Inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida, workers attach fins to the Saturn IB’s first stage. In the VAB, workers secure the first stage of the Saturn IB rocket onto the milk stool, perched on Mobile Launcher-1. Workers lift the second stage of the Saturn IB rocket prior to mating with the first stage. Workers lower a boilerplate Apollo spacecraft onto the Saturn IB rocket. The Saturn IB rocket, serial number SA-210, used for ASTP had a lengthy history. Contractors originally built its two stages in 1967, at a time when NASA planned many more Saturn IB flights to test Apollo spacecraft components in Earth orbit in preparation for the Moon landing. By 1968, however, after four uncrewed Saturn IB launches, only one launched a crew, Apollo 7. Four more Saturn IBs remained on reserve to launch crews as part of the Apollo Applications Program, renamed Skylab in 1970. Without an immediate mission, the two stages of SA-210 entered long-term storage in 1967. Workers later modified and refurbished the stages for ASTP before shipping them to KSC. The first stage arrived in April 1974 and the second stage in November 1972. 
      On Jan. 13, 1975, inside the cavernous VAB, workers stacked the Saturn IB rocket’s first stage onto Mobile Launcher-1 (ML-1), modified from its use to launch Saturn V rockets during the Apollo program with the addition of the milk stool pedestal. The milk stool, a 128-foot tall platform, allowed the Saturn IB to use the same Launch Umbilical Tower as the much larger Saturn V rocket at Launch Complex 39. The next day, workers lowered the second stage onto the first, followed by the Instrument Unit two days later. Finally, on Jan. 17 workers topped off the rocket with a boilerplate Apollo spacecraft while engineers continued testing the flight article in the MSOB. 

      The ASTP Apollo Command and Service Modules arrive at NASA’s Kennedy Space Center (KSC) in Florida. The ASTP Command Module arrives in KSC’s Manned Spacecraft Operations Building. The Command and Service Modules – CSM-111 – arrived at KSC from the Rockwell International plant in Downey, California, on Sept. 8, 1974, by C-5A Galaxy cargo plane. Rockwell had finished building the spacecraft in March 1970 and placed it in storage until July 1972. Modifications for ASTP took place between August 1972 and August 1974, following which Rockwell shipped the spacecraft to KSC. The sign on the shipping container bore the legend “From A to Soyuz – Apollo/Soyuz – Last and the Best.” Workers at KSC towed the modules to the MSOB for inspection and checkout, joined the two modules, and placed the combined spacecraft into a vacuum chamber.

The astronauts inside the CM in the altitude chamber. In the MSOB, the prime and backup ASTP crews conducted tests of their spacecraft in an altitude chamber. After both crews completed simulated runs in December 1974, the prime crew of Stafford, Brand, and Slayton suited up, entered the CM inside the chamber, closed the hatch, and conducted an actual test on Jan. 14, with the chamber simulating altitudes of up to 220,000 feet. Two days later, the backup crew of Bean, Evans, and Lousma completed a similar test. 

      he backup Apollo crew of Alan Bean, left, Ronald Evans, and Jack Lousma suit up in preparation for an altitude chamber test in the Command Module (CM). Workers assist backup crewmember Lousma into the CM. To solve the problem of the Apollo and Soyuz spacecraft operating at different atmospheric pressures and compositions and using incompatible docking mechanisms, engineers designed a Docking Module (DM) that acted as both an airlock and a transfer tunnel and a Docking System (DS) that allowed the two nations’ spacecraft to physically join in space. NASA contracted with Rockwell International to build the DM. Engineers equipped one end of the DM with the standard Apollo probe-and-drogue docking mechanism and the other end with the androgynous system that linked up with its opposite half installed on the modified Soyuz spacecraft. During launch, the DM rested inside the Spacecraft Lunar Module (LM) Adaptor (SLA) atop the rocket’s upper stage, much like the LM during Apollo flights. Once in orbit, the astronauts separated the CSM from the upper stage, turned the spacecraft around, docked with the DM and pulled it free. 
      Workers lower the DM into Chamber B in the Space Environment Simulation Laboratory at NASA’s Johnson Space Center in Houston. Workers lower the DM into Chamber B in the Space Environment Simulation Laboratory at NASA’s Johnson Space Center in Houston. After extensive vacuum testing in Chamber B of the Space Environment Simulation Laboratory at NASA’s Johnson Space Center in Houston, the flight DM arrived at KSC on Oct. 29, 1974, and workers prepared it for more testing in a vacuum chamber in the MSOB. The flight DS arrived at KSC on Jan. 3, 1975, and two weeks later workers installed it on the DM. On Jan. 27, engineers lowered the DM onto the CM in the altitude chamber to conduct a mechanical docking test. Engineers conducted 10 days of joint tests of television and audio equipment to ensure systems compatibility.

      55 Years Ago: Apollo 13 Prepares for Third Moon Landing 
      By NASA
      Following the historic year of 1969 that saw two successful Moon landings, 1970 opened on a more sober note. Ever-tightening federal budgets forced NASA to rescope its future lunar landing plans. The need for a Saturn V to launch an experimental space station in 1972 forced the cancellation of the final Moon landing mission and an overall stretching out of the Moon landing flights. Apollo 13 slipped to April, but the crew of James Lovell, Thomas “Ken” Mattingly, and Fred W. Haise and their backups John Young, John “Jack” Swigert, and Charles Duke continued intensive training for the landing at Fra Mauro. Training included practicing their surface excursions and water egress, along with time in spacecraft simulators. The three stages of the Apollo 14 Saturn V arrived at the launch site and workers began the stacking process for that mission now planned for October 1970. Scientists met in Houston to review the preliminary findings from their studies of the lunar samples returned by Apollo 11. 
      Apollo Program Changes 
      Apollo Moon landing plans in early 1970, with blue indicating completed landings, green planned landings at the time, and red canceled landings. Illustration of the Apollo Applications Program, later renamed Skylab, experimental space station then planned for 1972. On Jan. 4, 1970, NASA Deputy Administrator George Low announced the cancellation of Apollo 20, the final planned Apollo Moon landing mission. The agency needed the Saturn V rocket that would have launched Apollo 20 to launch the Apollo Applications Program (AAP) experimental space station, renamed Skylab in February 1970. Since previous NASA Administrator James Webb had precluded the building of any additional Saturn V rockets in 1968, this proved the only viable yet difficult solution.  
      In other program changes, on Jan. 13 NASA Administrator Thomas Paine addressed how NASA planned to deal with ongoing budgetary challenges. Lunar landing missions would now occur every six months instead of every four, and with the slip of Apollo 13 to April, Apollo 14 would now fly in October instead of July. Apollo 15 and 16 would fly in 1971, then AAP would launch in 1972, and three successive crews would spend, 28, 56, and 56 days aboard the station. Lunar landing missions would resume in 1973, with Apollo 17, 18, and 19 closing out the program by the following year.

Wernher von Braun in his office at NASA Headquarters in Washington, D.C. In addition to programmatic changes, several key management changes took place at NASA in January 1970. On Nov. 26, 1969, Christopher Kraft , the director of flight operations at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston, assumed the position of MSC deputy director. On Dec. 28, MSC Director Robert Gilruth named Sigurd “Sig” Sjoberg, deputy director of flight operations since 1963, to succeed Kraft. At NASA Headquarters in Washington, D.C., Associate Administrator for Manned Space Flight George Mueller resigned his position effective Dec. 10, 1969. To replace Mueller, on Jan. 8, NASA Administrator Paine named Dale Myers, vice president and general manager of the space shuttle program at North American Rockwell Corporation. On Jan. 27, Paine announced that Wernher von Braun, designer of the Saturn family of rockets and director of the Marshall Space Flight Center in Huntsville, Alabama, since its establishment in 1960, would move to NASA Headquarters and assume the position of deputy associate administrator for planning.

Between Jan. 5 and 8, 1970, several hundred scientists, including all 142 U.S. and international principal investigators provided with Apollo 11 samples, gathered in downtown Houston’s Albert Thomas Exhibit and Convention Center for the Apollo 11 Lunar Science Conference. During the conference, the scientists discussed the chemistry, mineralogy, and petrology of the lunar samples, the search for carbon compounds and any evidence of organic material, the results of dating of the samples, and the results returned by the Early Apollo Surface Experiments Package (EASEP). Senior NASA managers including Administrator Paine, Deputy Administrator Low, and Apollo Program Director Rocco Petrone attended the conference, and Apollo 11 astronaut Edwin “Buzz” Aldrin gave a keynote speech at a dinner reception. The prestigious journal Science dedicated its Jan. 30, 1970, edition to the papers presented at the conference, dubbing it “The Moon Issue”. The Lunar Science Conference evolved into an annual event, renamed the Lunar and Planetary Science Conference in 1978, and continues to attract scientists from around the world to discuss the latest developments in lunar and planetary exploration.

Actress June Lockhart, an avid space enthusiast, interviewed them during the TV broadcast of the event. As President Richard Nixon had earlier requested, Conrad, Gordon, and Bean and their wives paid a visit to former President Lyndon B. Johnson and First Lady Lady Bird Johnson at their ranch near Fredericksburg, Texas, on Jan. 14, 1970. The astronauts described their mission to the former President and Mrs. Johnson.

A technician examines the Surveyor 3 camera returned by the Apollo 12 astronauts. Managers released the Apollo 12 Command Module (CM) Yankee Clipper from quarantine and shipped it back to its manufacturer, the North American Rockwell plant in Downey, California, on Jan. 12. Engineers there completed a thorough inspection of the spacecraft and eventually prepared it for public display. NASA transferred Yankee Clipper to the Smithsonian Institution in 1973, and today the capsule resides at the Virginia Air & Space Center in Hampton, Virginia. NASA also released from quarantine the lunar samples and the parts of the Surveyor 3 spacecraft returned by the Apollo 12 astronauts. The scientists received their allocated samples in mid-February, while after initial examination in the Lunar Receiving Laboratory (LRL) the Surveyor parts arrived at NASA’s Jet Propulsion Laboratory in Pasadena, California, for detailed analysis. 
      Apollo 13 
      As the first step in the programmatic rescheduling of all Moon landings, on Jan. 7, NASA announced the delay of the Apollo 13 launch from March 12 to April 11. The Saturn V rocket topped with the Apollo spacecraft had rolled out the previous December to Launch Pad 39A where workers began tests on the vehicle. The prime crew of Lovell, Mattingly, and Haise, and their backups Young, Swigert, and Duke, continued to train for the 10-day mission to land in the Fra Mauro region of the Moon.

Apollo 13 prime crew members Lovell, Mattingly, and Haise completed their water egress training in the Gulf of Mexico near the coast of Galveston, Texas, on Jan. 24. With support from the Motorized Vessel Retriever, the three astronauts entered a boilerplate Apollo CM. Sailors lowered the capsule into the water, first in the Stable 2 or apex down position. Three self-inflating balloons righted the spacecraft into the Stable 1 apex up position within a few minutes. With assistance from the recovery team, Lovell, Mattingly, and Haise exited the spacecraft onto a life raft. A helicopter lifted them out of the life rafts using Billy Pugh nets and returned them to Retriever. Later that day, the astronauts returned to the MSC to examine Moon rocks in the LRL that the Apollo 12 astronauts had returned the previous November. 
      During their 33.5 hours on the Moon’s surface, Lovell and Haise planned to conduct two four-hour spacewalks to set up the Apollo Lunar Surface Experiment Package (ALSEP), a suite of five investigations designed to collect data about the lunar environment after the astronauts’ departure, and to conduct geologic explorations of the landing site. Mattingly planned to remain in the Command and Service Module (CSM), conducting geologic observations from lunar orbit including photographing potential future landing sites. Lovell and Haise conducted several simulations of the spacewalk timelines, including setting up the ALSEP equipment, practicing taking core samples, and photographing their activities for documentation purposes. They and their backups conducted practice sessions with the partial gravity simulator, also known as POGO, an arrangement of harnesses and servos that simulated walking in the lunar one-sixth gravity. Lovell and Young completed several flights in the Lunar Landing Training Vehicle (LLTV) that simulated the flying characteristics of the Lunar Module (LM) for the final several hundred feet of the descent to the surface.

In the LRL, technicians prepared the Apollo Lunar Sample Return Containers (ALSRC), or rock boxes, for Apollo 13. Like all missions, Apollo 13 carried two ALSRCs, with each box and lid manufactured from a single block of aluminum. Workers placed sample containers and bags and two 2-cm core sample tubes inside the two ALSRCs. Once loaded, technicians sealed the boxes under vacuum conditions so that they would not contain pressure greater than lunar ambient conditions. Engineers at MSC prepared the American flag that Lovell and Haise planned to plant on the Moon for stowage on the LM’s forward landing strut.

As part of the rescheduling of Moon missions, NASA delayed the launch of the next flight, Apollo 14, from July to October 1970. The CSM and the LM had arrived at NASA’s Kennedy Space Center (KSC) in Florida late in 1969 and technicians conducted tests on the vehicles in the Manned Spacecraft Operations Building (MSOB). On Jan. 12, workers lowered the ascent stage of the LM onto the CSM to perform a docking test – the next time the two vehicles docked they would be on the way to the Moon and the test verified their compatibility. Workers mated the two stages of the LM on Jan. 20.

The three stages of the Apollo 14 Saturn V arrived in KSC’s cavernous Vehicle Assembly Building (VAB) in mid-January and while workers stacked the first stage on its Mobile Launch Platform on Jan. 14, they delayed stacking the remainder of the rocket stages until May 1970. That decision proved fortunate, since engineers needed to modify the second stage engines following the pogo oscillations experienced during the Apollo 13 launch.

A team led by project design engineer William Creasy developed the MET based on recommendations from the first two Moon landing crews on how to improve efficiency on the lunar surface. Creasy and his team demonstrated the MET to Sally LaMere, editor of The Roundup, MSC’s employee newsletter. Three support astronauts, William Pogue, Anthony “Tony” England, and Gordon Fullerton tested the MET prototype in simulated one-sixth lunar gravity during parabolic aircraft flights.

As part of NASA’s Artemis campaign, the agency will send astronauts to the Moon to prepare for future human exploration of Mars; inspiring Artemis Generation explorers and ensuring the United States continues to lead in space exploration and discovery.
