Preparations for Next Moonwalk Simulations Underway (and Underwater)
On Christmas Day in 1968, the three-man Apollo 8 crew of Frank Borman, Jim Lovell, and Bill Anders found a surprise in their food locker: a specially packed Christmas dinner wrapped in foil and decorated with red and green ribbons. Something as simple as a “home-cooked meal,” or as close as NASA could get for a spaceflight at the time, greatly improved the crew’s morale and appetite. More importantly, the meal marked a turning point in space food history.

Lovell Jr., command module pilot; William A. Anders, lunar module pilot; and Frank Borman, commander.NASA On their way to the Moon, the Apollo 8 crew was not very hungry. Food scientist Malcolm Smith later documented just how little the crew ate. Borman ate the least of the three, eating only 881 calories on day two, which concerned flight surgeon Chuck Berry. Most of the food, Borman later explained, was “unappetizing.” The crew ate few of the compressed, bite-sized items, and when they rehydrated their meals, the food took on the flavor of their wrappings instead of the actual food in the container. “If that doesn’t sound like a rousing endorsement, it isn’t,” he told viewers watching the Apollo 8 crew in space ahead of their surprise meal. As Anders demonstrated to the television audience how the astronauts prepared a meal and ate in space, Borman announced his wish, that folks back on Earth would “have better Christmas dinners” than the one the flight crew would be consuming that day.1
If that doesn’t sound like a rousing endorsement, it isn’t.

Apollo 8 Astronaut
Over the 1960s, there were many complaints about the food from astronauts and others working at the Manned Spacecraft Center (now NASA’s Johnson Space Center). After evaluating the food that the Apollo 8 crew would be consuming onboard their upcoming flight, Apollo 9 astronaut Jim McDivitt penciled a note to the food lab about his in-flight preferences. Using the back of the Apollo 8 crew menu, he directed them to decrease the number of compressed bite-sized items “to a bare minimum” and to include more meat and potato items. “I get awfully hungry,” he wrote, “and I’m afraid I’m going to starve to death on that menu.”2
In 1969, Rita Rapp, a physiologist who led the Apollo Food System team, asked Donald Arabian, head of the Mission Evaluation Room, to evaluate a four-day food supply used for the Apollo missions. Arabian identified himself as someone who “would eat almost anything. … you might say [I am] somewhat of a human garbage can.” But even he found the food lacked the flavor, aroma, appearance, texture, and taste he was accustomed to. At the end of his four-day assessment he concluded that “the pleasures of eating were lost to the point where interest in eating was essentially curtailed.”3
Food used on the Gemini-Titan IV flight. Packages include beef sandwich cubes, strawberry cereal cubes, dehydrated peaches, and dehydrated beef and gravy. A water gun on the Gemini spacecraft is used to reconstitute the dehydrated food and scissors are used to open the packaging.NASA Apollo 8 commander Frank Borman concurred with Arabian’s assessment of the Apollo food. The one item Borman enjoyed? It was the contents of the Christmas meal wrapped in ribbons: turkey and gravy. The Christmas dinner was so delicious that the crew contacted Houston to inform them of their good fortune. “It appears that we did a great injustice to the food people,” Lovell told capsule communicator (CAPCOM) Mike Collins. “Just after our TV show, Santa Claus brought us a TV dinner each; it was delicious. Turkey and gravy, cranberry sauce, grape punch; [it was] outstanding.” In response, Collins expressed delight in hearing the good news but shared that the flight control team was not as lucky. Instead, they were “eating cold coffee and baloney sandwiches.”4
The Apollo 8 Christmas menu included dehydrated grape drink, cranberry-applesauce, and coffee, as well as a wetpack containing turkey and gravy.U.S. Natick Soldier Systems Center Photographic Collection The Apollo 8 meal was a “breakthrough.” Until that mission, the food choices for Apollo crews were limited to freeze dried foods that required water to be added before they could be consumed, and ready-to-eat compressed foods formed into cubes. Most space food was highly processed. On this mission NASA introduced the “wetpack”: a thermostabilized package of turkey and gravy that retained its normal water content and could be eaten with a spoon. Astronauts had consumed thermostabilized pureed food on the Project Mercury missions in the early 1960s, but never chunks of meat like turkey. For the Project Gemini and Apollo 7 spaceflights, astronauts used their fingers to pop bite-sized cubes of food into their mouths and zero-G feeder tubes to consume rehydrated food. The inclusion of the wetpack for the Apollo 8 crew was years in the making. The U.S. Army Natick Labs in Massachusetts developed the packaging, and the U.S. Air Force conducted numerous parabolic flights to test eating from the package with a spoon.5
Smith called the meal a real “morale booster.” He noted several reasons for its appeal: the new packaging allowed the astronauts to see and smell the turkey and gravy; the meat’s texture and flavor were not altered by adding water from the spacecraft or the rehydration process; and finally, the crew did not have to go through the process of adding water, kneading the package, and then waiting to consume their meal. Smith concluded that the Christmas dinner demonstrated “the importance of the methods of presentation and serving of food.” Eating from a spoon instead of the zero-G feeder improved the inflight feeding experience, mimicking the way people eat on Earth: using utensils, not squirting pureed food out of a pouch into their mouths. Using a spoon also simplified eating and meal preparation. NASA added more wetpacks onboard Apollo 9, and the crew experimented eating other foods, including a rehydrated meal item, with the spoon.6
Malcolm Smith demonstrates eating space food.NASA Food was one of the few creature comforts the crew had on the Apollo 8 flight, and this meal demonstrated the psychological importance of being able to smell, taste, and see the turkey prior to consuming their meal, something that was lacking in the first four days of the flight. Seeing appetizing food triggers hunger and encourages eating. In other words, if food looks and smells good, then it must taste good. Little things like this improvement to the Apollo Food System made a huge difference to the crews who simply wanted some of the same eating experiences in orbit and on the Moon that they enjoyed on Earth.

Rector (NRAO/AUI/NSF and NOIRLab/NSF/AURA) and B.A. Wolpa (NOIRLab/NSF/AURA); Infrared: NASA/NSF/IPAC/CalTech/Univ. of Massachusetts; Image Processing: NASA/CXC/SAO/L. Frattare & J.Major This new image of NGC 2264, also known as the “Christmas Tree Cluster,” shows the shape of a cosmic tree with the glow of stellar lights. NGC 2264 is, in fact, a cluster of young stars — with ages between about one and five million years old — in our Milky Way about 2,500 light-years away from Earth. The stars in NGC 2264 are both smaller and larger than the Sun, ranging from some with less than a tenth the mass of the Sun to others containing about seven solar masses.
This new composite image enhances the resemblance to a Christmas tree through choices of color and rotation. The blue and white lights (which blink in the animated version of this image) are young stars that give off X-rays detected by NASA’s Chandra X-ray Observatory. Optical data from the National Science Foundation’s WIYN 0.9-meter telescope on Kitt Peak shows gas in the nebula in green, corresponding to the “pine needles” of the tree, and infrared data from the Two Micron All Sky Survey shows foreground and background stars in white. This image has been rotated clockwise by about 160 degrees from the astronomer’s standard of North pointing upward, so that it appears like the top of the tree is toward the top of the image.

This composite image shows the Christmas Tree Cluster. The blue and white lights (which blink in the animated version of this image) are young stars that give off X-rays detected by NASA’s Chandra X-ray Observatory. Optical data from the National Science Foundation’s WIYN 0.9-meter telescope on Kitt Peak shows gas in the nebula in green, corresponding to the “pine needles” of the tree, and infrared data from the Two Micron All Sky Survey shows foreground and background stars in white. This image has been rotated clockwise by about 160 degrees from the astronomer’s standard of North pointing upward, so that it appears like the top of the tree is toward the top of the image. Young stars, like those in NGC 2264, are volatile and undergo strong flares in X-rays and other types of variations seen in different types of light. The coordinated, blinking variations shown in this animation, however, are artificial, to emphasize the locations of the stars seen in X-rays and highlight the similarity of this object to a Christmas tree. In reality the variations of the stars are not synchronized.
The variations observed by Chandra and other telescopes are caused by several different processes. Some of these are related to activity involving magnetic fields, including flares like those undergone by the Sun — but much more powerful — and hot spots and dark regions on the surfaces of the stars that go in and out of view as the stars rotate. There can also be changes in the thickness of gas obscuring the stars, and changes in the amount of material still falling onto the stars from disks of surrounding gas.

Visual Description:
This release features a composite image of a cluster of young stars looking decidedly like a cosmic Christmas tree! The cluster, known as NGC 2264, is in our Milky Way Galaxy, about 2,500 light-years from Earth. Some of the stars in the cluster are relatively small, and some are relatively large, ranging from one tenth to seven times the mass of our Sun.
In this composite image, the cluster’s resemblance to a Christmas tree has been enhanced through image rotation and color choices. Optical data is represented by wispy green lines and shapes, which creates the boughs and needles of the tree shape. X-rays detected by Chandra are presented as blue and white lights, and resemble glowing dots of light on the tree. Infrared data show foreground and background stars as gleaming specks of white against the blackness of space. The image has been rotated by about 150 degrees from the astronomer’s standard of North pointing upwards. This puts the peak of the roughly conical tree shape near the top of the image, though it doesn’t address the slight bare patch in the tree’s branches, at our lower right, which should probably be turned to the corner.
In this release, the festive cluster is presented as both a static image, and as a short animation. In the animation, blue and white X-ray dots from Chandra flicker and twinkle on the tree, like the lights on a Christmas tree.
