If you design a new tool for use on Earth, it is easy to test and practice using that tool in its intended environment. But what if that tool is destined for lunar orbit or will be used by astronauts on the surface of the Moon?
NASA’s Simulation and Graphics Branch can help with that. Based at Johnson Space Center in Houston, the branch’s high-fidelity, real-time graphical simulations support in-depth engineering analyses and crew training, ensuring the safety, efficiency, and success of complex space endeavors before execution. The team manages multiple facilities that provide these simulations, including the Prototype Immersive Technologies (PIT) Lab, Virtual Reality Training Lab, and the Systems Engineering Simulator (SES).
Lee Bingham is an aerospace engineer on the simulation and graphics team. His work includes developing simulations and visualizations for the NASA Exploration Systems Simulations team and providing technical guidance on simulation and graphics integration for branch-managed facilities. He also leads the branch’s human-in-the-loop Test Sim and Graphics Team, the Digital Lunar Exploration Sites Unreal Simulation Tool (DUST), and the Lunar Surface Mixed-Reality with the Active Response Gravity Offload System (ARGOS) projects.

DUST has supported several human-in-the-loop studies for NASA. It has also been shared with external collaborators and made available to the public through the NASA Software Catalog.
Bingham has kept busy during his nearly nine years at Johnson and said learning to manage and balance support for multiple projects and customers was very challenging at first. “I would say ‘yes’ to pretty much anything anyone asked me to do and would end up burning myself out by working extra-long hours to meet milestones and deliverables,” he said. “It has been important to maintain a good work-life balance and avoid overcommitting myself while meeting demanding expectations.”

Image courtesy of Lee Bingham Bingham has also learned the importance of teamwork and collaboration. “You can’t be an expert at everything or do everything yourself,” he said. “Develop your skills, practice them regularly, and master them over time but be willing to ask for help and advice. And be sure to recognize and acknowledge your coworkers and teammates when they go above and beyond or achieve something remarkable.”

On March 23, 1965, the United States launched the Gemini III spacecraft with astronauts Virgil “Gus” Grissom and John Young aboard, America’s first two-person spaceflight. Grissom earned the honor as the first person to enter space twice and Young as the first member of the second group of astronauts to fly in space. During their three-orbit flight they carried out the first orbital maneuvers of a crewed spacecraft, a critical step toward demonstrating rendezvous and docking. Grissom and Young brought Gemini 3 to a safe splashdown in the Atlantic Ocean. Their ground-breaking mission led the way to nine more successful Gemini missions in less than two years to demonstrate the techniques required for a Moon landing. Gemini 3 marked the last spaceflight controlled from Cape Kennedy, that function shifting permanently to a new facility in Houston.
In one of the first uses of the auditorium at the Manned Spacecraft Center, now NASA’s Johnson Space Center in Houston, managers announce the prime and backup Gemini III crews. NASA NASA astronauts Virgil “Gus” Grissom and John Young, the Gemini III prime crew. NASA Grissom, foreground, and Young in their capsule prior to launch.NASA On April 13, 1964, just five days after the uncrewed Gemini I mission, in the newly open auditorium at the Manned Spacecraft Center, now NASA’s Johnson Space Center in Houston, Director Robert Gilruth introduced the Gemini III crew to the press. NASA assigned Mercury 4 veteran Grissom and Group 2 astronaut Young as the prime crew, with Mercury 8 veteran Walter Schirra and Group 2 astronaut Thomas Stafford serving as their backups. The primary goals of Project Gemini included proving the techniques required for the Apollo Program to fulfil President John F. Kennedy’s goal of landing a man on the Moon and returning him safely to Earth before the end of the 1960s. Demonstrating rendezvous and docking between two spacecraft ranked as a high priority for Project Gemini.
Liftoff of Gemini III.NASA The uncrewed Gemini I and II missions validated the spacecraft’s design, reliability, and heat shield, clearing the way to launch Gemini III with a crew. On March 23, 1965, after donning their new Gemini spacesuits, Grissom and Young rode the transfer van to Launch Pad 19 at Cape Kennedy in Florida. They rode the elevator to their Gemini spacecraft atop its Titan II rocket where technicians assisted them in climbing into the capsule. At 9:24 a.m. EST, the Titan’s first stage engines ignited, and Gemini III rose from the launch pad.

Grissom became the first human to enter space a second time. While engineers monitored the countdown from the Launch Pad 19 blockhouse, once in orbit flight controllers in the Mission Control Center at the Cape took over. Controllers in the new Mission Control Center at the Manned Spacecraft Center, now the Johnson Space Center in Houston, staffed consoles and monitored the mission in a backup capacity. Beginning with Gemini IV, control of all American human spaceflights shifted permanently to the Houston facility.
Gemini III entered an orbit of 100 miles by 139 miles above the Earth. Near the end of the first orbit, while passing over Texas, Grissom and Young fired their spacecraft’s thrusters for one minute, 14 seconds. “They appear to be firing good,” said Young, confirming the success of the maneuver. The change in velocity adjusted their orbit to 97 miles by 105 miles. A second burn 45 minutes later altered the orbital inclination by 0.02 degrees. Another task for the crew involved testing new food and packaging developed for Gemini. As an off-the-menu item, Young had stowed a corned beef on rye sandwich in his suit pocket before flight, and both he and Grissom took a bite before stowing it away, concerned about crumbs from the sandwich floating free in the cabin.
Shortly after splashdown, Gemini III astronaut Virgil “Gus” Grissom exits the spacecraft as crewmate John Young waits in the life raft. NASA Sailors hoist the Gemini III spacecraft aboard the prime recovery ship U.S.S. Intrepid.NASA Young, left, and Grissom stand with their spacecraft aboard Intrepid. NASA Near the end of their third revolution, Grissom and Young prepared for the retrofire burn to bring them out of orbit. They oriented Gemini III with its blunt end facing forward and completed a final orbital maneuver to lower the low point of their orbit to 45 miles, ensuring reentry even if the retrorockets failed to fire. They jettisoned the rearmost adapter section, exposing the retrorockets that fired successfully, bringing the spacecraft out of orbit. They jettisoned the retrograde section, exposing Gemini’s heat shield. Minutes later, they encountered the upper layers of Earth’s atmosphere at 400,000 feet, and he buildup of ionized gases caused a temporary loss of communication between the spacecraft and Mission Control. At 50,000 feet, Grissom deployed the drogue parachute to stabilize and slow the spacecraft, followed by the main parachute at 10,600 feet. Splashdown occurred in the Atlantic Ocean near Grand Turk Island, about 52 miles short of the planned point, after a flight of 4 hours, 52 minutes, 31 seconds.

Intrepid, arriving there one hour and 12 minutes after splashdown. On board the carrier, the astronauts received a medical checkup and a telephone call from President Lyndon B. Johnson. The ship sailed to pick up the spacecraft and sailors hoisted it aboard less than three hours after landing. The day after splashdown, Grissom and Young flew to Cape Kennedy for debriefings, a continuation of the medical examinations begun on the carrier, and a press conference. Following visits to the White House, New York, and Chicago, the astronauts returned home to Houston on March 31. The next day, Gilruth welcomed them back to the Manned Spacecraft Center, where in front of the main administration building, workers raised an American flag that Grissom and Young had carried on their mission. That flag flew during every subsequent Gemini mission.

7 Min Read Fallout from the Unauthorized Gemini III Space Sandwich
Astronaut John W. Young, the pilot for Gemini III, checks over his helmet prior to flight. Credits: NASA “I hid a sandwich in my spacesuit,” Astronaut John W. Young confessed in the April 2, 1965, issue of Life Magazine. The conversation about and the consumption of the sandwich, which lasted only about 30 seconds during the Gemini III flight, became a serious matter that drew the ire of Congress and NASA’s administrator after the crew returned home. Congress was particularly upset and brought the matter to leadership’s attention at hearings about NASA’s 1966 budget. Representative George E. Shipley was especially disgusted, knowing how much money and time NASA had spent to prepare the Gemini III spacecraft for launch. The fact that a crewmember brought something into the crew cabin, which Shipley likened to a “surgeon’s operating room,” put the techniques used to prevent a spaceflight mission from failing at risk; crumbs could have made their way behind instrument panels interfering with the operation of flight equipment and the loss of the mission and its crew. Shipley called Young’s antics “foolish” and asked NASA leaders to share their thoughts.
A Beef with Corned Beef
George Mueller, associate administrator for Manned Space Flight, stated unequivocally that the agency did not “approve [of] unauthorized objects such as sandwiches going on board the spacecraft.” And he promised Shipley that NASA has “taken steps, obviously, to prevent recurrence of corned beef sandwiches in future flights. There was no detriment to the experimental program that was carried on, nor was there any detriment to the actual carrying out of the mission because of the ingestion of the sandwich.” Manned Spacecraft Center Director Robert R. Gilruth was more forgiving of Young’s decision. These sort of antics, he told the committee, helped the crews to “break up the strain” of spaceflight, and he hesitated “to be too strict in the future by laying down a lot of rules for men who have this responsibility and who, in all the flights so far, have done such good jobs.” Webb disagreed and said, “this is the United States of America’s space program and, as a matter of policy, we are not going to permit individuals to superimpose their judgment as to what is going to be taken on these flights. I think it is fine for Dr. Gilruth to take a very strong position with respect to the individuality of these men, but from those of us who have to look at the totality of the matter, this was not an adequate performance by an astronaut.”
The loss of a Gemini mission, especially one so early in the program, would have been particularly challenging for an agency attempting to land humans on the Moon where each mission built on the previous flight. The United States was in a race with the Soviet Union, and for Congress at least, the purpose of Gemini and the cost of the space program was far too serious for these sorts of fun and games. For NASA Administrator James Webb, it was a sign that Gilruth was too lax when it came to managing his astronauts. Gemini III was just one example of the lack of control he noticed, and he pressed Gilruth for a report on the sandwich incident to determine if Young should be disciplined or at the very least reprimanded.
The In-Flight Meal
Young hatched the idea during training, when his commander, Virgil I. “Gus” Grissom grew “bored” with the food they practiced with for the mission. Grissom regularly complained about the dehydrated “delicacies” food scientists concocted. Bringing a sandwich onboard, an item that was freshly made and did not have to be rehydrated, “seemed like a fun idea at the time” to Young.
Astronauts Gus Grissom (foreground), command pilot; and John Young, pilot, are shown inside their Gemini III spacecraft as they prepared for their launch from Cape Kennedy, Florida, on March 23, 1965.NASA One of the goals of their flight was to evaluate NASA’s flight food packaging and whether the containers leaked when foods were reconstituted, as well as the procedures for disposing of the meal and its packaging after eating. Foods included rehydratable items such as chicken bites, applesauce, or drinks, and compressed foods such as brownie bites. The Gemini food system was not haute cuisine, however, and crews complained about its taste. Young described the chicken bites as “barely edible” in his post-flight debriefing. Don L. Lind, a scientist-astronaut selected in 1967, described the early Gemini food as “strange.” Their class took some to jungle survival training in Panama, and while no one wanted to eat it on the first two days, by the third day they were so hungry that they were willing to give it a try. Another problem was that all rehydrated meals for Gemini were mixed with cold water, which made them less appetizing than a hot meal.
Food packets planned for the Gemini III flight, including dehydrated beef pot roast, bacon and egg bites, toasted bread cubes, orange juice and a wet wipe. The astronaut’s method for rehydrating a pouch of dehydrated food with water is shown in the top left.NASA A freshly made corned beef sandwich made at a local restaurant sounded like a better option, so Young had fellow astronaut and backup command pilot Walter M. “Wally” Schirra pick one up. Schirra purchased the sandwich for Young, and as he headed out to the launchpad, Young put it in the pocket of his pressure suit.
Nearly two hours into the flight, as Young started his food and waste evaluation, he pulled out the sandwich from his suit and offered it to his commander. As captured on the air-to-ground recordings, Grissom asked what it was and where it came from. “I brought it with me,” Young responded, “Let’s see how it tastes.” He didn’t expect the sandwich to be so pungent, “Smells, doesn’t it?” Grissom took a bite but found the rye crumbled so he placed the sandwich in his suit pocket to prevent the crumbs from floating about the cabin.
Where did that come from?

Gemini III Commander
Two days later, nearly a thousand members of the media from the United States and around the world gathered to hear from the crew and NASA management at the postflight press conference at the Carriage House Motel in Cocoa Beach, Florida. Space reporter Bill Hines asked Young about the sandwich, erroneously referring to it as a “baloney sandwich,” and what happened when Gus was offered a taste. “And,” he asked, “what became of the sandwich?” Young seemed surprised, “How did you find out about that?” and then laughed adding Grissom “ate the sandwich.”

Debus, director of Kennedy Space Center, Christopher C. Kraft, Jr., MSC assistant director for Flight Operations, astronauts John Young and Gus Grissom, Dr. Robert R. Gilruth, MSC director, Dr. Robert C. Seamans, NASA associate administrator, and Julian Scheer, assistant administrator for NASA’s Office of Public Affairs.NASA Carry-on Restrictions for Spaceflights
Ironically the Gemini Program offered astronauts more control over their flights than during Project Mercury, including the ability to maneuver their spacecraft and to be more independent from Mission Control; but the uproar over this event led NASA to draft rules about what astronauts could and could not take onboard a spacecraft. Starting with Gemini IV, flight crews had to present a list of items they planned to take on their missions. Prohibited items naturally included sandwiches as well as bulky or heavy items or metal that could negatively impact the operation of spacecraft equipment. (NASA still allowed astronauts to take personal items such as wedding bands or coins for families and friends in their personal preference kit.)
Young never received a formal reprimand for the incident but was made aware of Congress’s frustration. Others in the corps were advised to avoid similar stunts and to focus on the mission. The decision to bring a sandwich onboard did not have a negative impact on Young’s career. He was the first astronaut to fly to space six times —two Gemini missions; two Apollo missions, including the dress rehearsal for the first lunar landing; and two space shuttle missions including STS-1, known as the bravest test flight in history. He also served as chief of the Astronaut Office for 13 years.
