The new year of 1969 dawned with optimism that NASA would meet President John F. Kennedy’s goal of landing a man on the Moon and returning him safely to the Earth. The previous year saw four Apollo missions, two uncrewed and two carrying three astronauts each, test different components of the lunar landing architecture, culminating with Apollo 8’s December flight around the Moon. Challenges remaining for the new year included testing the Lunar Module (LM) with a crew, first in Earth orbit, and then in lunar orbit, a flight that served as a dress rehearsal for the Moon landing that could take place on the following mission. With flights occurring every two months, engineers at NASA’s Kennedy Space Center (KSC) in Florida processed three spacecraft and launch vehicles in parallel.

Recovering from the fire

The years 1967 and 1968 proved turbulent for the world. For NASA, the focus remained on recovering from the tragic Apollo 1 fire in time to meet President Kennedy’s fast approaching end of the decade deadline. The fire resulted in a thorough redesign of the Command Module (CM) to reduce flammability risks and to include an easy to open hatch. Engineers also removed flammable materials from the Lunar Module (LM). In November 1967, the first flight of the Saturn V carried Apollo 4 on a nine-hour uncrewed mission to test the CM’s heat shield. Apollo 5 in January 1968 completed an uncrewed test of the LM so successful that NASA decided to cancel a second test. Although fraught with problems, the April 1968 flight of Apollo 6 tested the CM heat shield once again. Managers believed that engineers could solve the problems encountered during this mission and declared that the next Saturn V would carry a crew.

Apollo 7 and 8

By October 1968, thorough ground testing of the Apollo spacecraft enabled the first crewed mission since the fire. Apollo 7 astronauts Walter M. Schirra, Donn F. Eisele, and R. Walter Cunningham successfully completed the 11-day test flight, achieving all mission objectives. In August, with LM development running behind schedule, senior NASA managers began discussions of sending Apollo 8 on a circumlunar flight, pending the outcome of Apollo 7. With that hurdle successfully cleared, astronauts Frank Borman, James A. Lovell, and William A. Anders orbited the Moon 10 times during Christmas 1968, taking a giant leap toward achieving the Moon landing.

With their space missions completed, the Apollo 7 and 8 crews remained busy with events celebrating their successes. On Jan. 3, 1969, TIME magazine named Apollo 8 astronauts Borman, Lovell, and Anders their Men of the Year for 1968. Kicking off a whirlwind of events, on Jan. 9, outgoing President Lyndon B. Johnson welcomed them to the White House, where he presented them with NASA Distinguished Service Medals. They in turn presented him with a copy of the famous Earthrise photograph. Accompanied by Vice President Hubert H. Humphrey, Borman, Lovell, and Anders rode in a motorcade down Pennsylvania Avenue to the Capitol where the astronauts addressed a joint meeting of Congress. From there, they proceeded to the State Department for a press conference, their day ending with a dinner in their honor at the Smithsonian Institution.

On Jan. 10, New York City held a tickertape parade for Borman, Lovell, and Anders. Mayor John V. Lindsay presented them with Medals of the City of New York, after which they attended a luncheon at Lincoln Center, a reception at the United Nations, and dinner at the Waldorf-Astoria Hotel. The next day, in 15-degree weather, they spoke to a crowd of about 1,500 people at Newark Airport before boarding a plane for much warmer Miami, where on Jan. 12 they attended Super Bowl III, and led the Orange Bowl crowd in reciting the Pledge of Allegiance.

A crowd estimated at about 250,000 welcomed Borman, Lovell, and Anders home to Houston on Jan. 13. In a ceremony outside the Albert Thomas Convention Center, Mayor Louie Welch presented them with bronze medals for heroism, and the astronauts presented Welch and Texas Governor John B. Connally with plaques bearing Texas flags they had flown to the Moon as well as a framed copy of the Earthrise photograph. The astronauts took part in the largest parade in the city’s history. The next day, the city of Chicago welcomed Borman, Lovell, and Anders. An estimated 1.5 million people cheered them on their parade route to a reception where they received honors from city council.

On Jan. 20, Apollo 7 astronauts Schirra, Eisele, and Cunningham rode in President Richard M. Nixon’s inauguration parade in Washington, D.C. Their spacecraft and a LM mockup rode on a float behind them. Ten days later, the new President invited Apollo 8 astronauts Borman, Lovell, and Anders to the White House where he announced that Borman and his family would embark on an 18-day goodwill tour of eight European nations, starting on Feb. 2.

Apollo 9

The LM remained the one component of the lunar landing architecture not yet tested by astronauts in space. That task fell to James A. McDivitt, David R. Scott, and Russell L. Schweickart, the crew of Apollo 9. They and their backups Charles “Pete” Conrad, Richard F. Gordon, and Alan L. Bean spent many hours in the LM simulators and training for the spacewalk component of the mission.

In preparation for the Apollo 9 spacewalk, astronaut Russell L.

Bean train for the spacewalk in the KC-135 zero-gravity aircraft.

Apollo 9’s 10-day mission would take place in the relative safety of low Earth orbit. After docking with the LM, the crew’s first major task involved the first spacewalk of the Apollo program and the only in-space test of the new A7L spacesuit before the Moon landing. McDivitt and Schweickart planned to enter the LM, leaving Scott in the CM. Schweickart and Scott would each perform a spacewalk from their respective spacecraft. Scott would only stand in the open CM hatch while Schweickart would exit via the LM’s front hatch onto its porch, translate over to the CM using handrails, retrieve materials samples mounted on the spacecraft’s exterior and return back to the LM, spending two hours outside. This spacewalk tested the ability of crews to transfer through open space, in case a malfunction with the tunnel or hatches between the two spacecraft prevented an internal transfer. The day after the spacewalk, McDivitt and Schweickart planned to undock the LM, leaving Scott in the CM, fly it up to 100 miles away, testing its descent and ascent stages before returning to Scott in the CM who would perform the rendezvous and docking.

The first of the three vehicles in processing flow at KSC, Apollo 9 rolled out from High Bay 3 of the Vehicle Assembly Building (VAB) to Launch Pad 39A on Jan. 3, just 13 days after Apollo 8 launched from the same facility, causing relatively minor damage. Stages of the Apollo 9 Saturn V had arrived at KSC during the spring and summer of 1968, the LM arrived in June and the Command and Service Modules (CSM) in October. Workers completed stacking of the Saturn V in October, adding the Apollo spacecraft in early December. On Jan. 8, NASA announced Feb. 28, 1969, as the planned launch date for Apollo 9.

Workers at the pad immediately began to prepare the vehicle for flight, including software integration tests with the Mission Control Center at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston. On Jan. 15, the prime and backup crews conducted emergency egress training from their spacecraft at Launch Pad 39A. Launch controllers at KSC successfully completed the Flight Readiness Test, the final major overall test of the vehicle’s systems, between Jan. 19 and 22. During a Jan. 25 press conference at the Grumman Aircraft and Engineering Corporation in Bethpage, New York, manufacturer of the LM, the Apollo 9 astronauts provided reporters with an overview of their mission.

Apollo 10

Assuming Apollo 9 met its objectives and the LM proved space worthy in Earth orbit, in May Apollo 10 would repeat many of those tests in lunar orbit, including flying to within nine miles of the Moon’s surface.

In November 1968, just six months before the planned launch date, NASA officially named the Apollo 10 crew. The prime crew consisted of Thomas P. Stafford, John W. Young, and Eugene A. Cernan. All had flown Gemini missions and had recently served as the Apollo 7 backup crew. L. Gordon Cooper, Donn F. Eisele, and Edgar D. Mitchell served as their backups.

In the VAB’s High Bay 2, workers had completed stacking the Apollo 10 Saturn V’s three stages by the final days of 1968, while their colleagues prepared to roll Apollo 9’s rocket to the pad a few days later. In the nearby Manned Spacecraft Operations Building (MSOB), prime and backup crews completed altitude tests of the LM in December and workers conducted a docking test between the LM and the CM. On Jan. 16, Stafford, Young, and Cernan completed their altitude test of the CM, followed by Cooper, Eisele, and Mitchell the next day. Workers removed the spacecraft from the altitude chamber in preparation for its rollover to the VAB in early February for stacking onto the rocket.

Apollo 11

Assuming Apollo 9 and 10 accomplished their objectives, Apollo 11 would attempt the first Moon landing in July. Should Apollo 11 not succeed, NASA would try again with Apollo 12 in September and even Apollo 13 in November or December. Spacecraft and rocket manufacturers continued building components to meet that aggressive schedule.

On Jan. 9, a mere six months before the planned launch date, NASA formally announced the Apollo 11 crew, the second all-veteran three-person crew after Apollo 10 – and the last all-veteran crew until STS-26 in 1988. The next day, NASA introduced the Apollo 11 crew during a press conference at MSC. The prime crew consisted of Neil A. Armstrong, Michael Collins, and Edwin E. “Buzz” Aldrin. Each astronaut had flown one Gemini mission. Armstrong and Aldrin had served on the backup crew for Apollo 8 while Collins was initially a member of the prime Apollo 8 crew until a bone spur in his neck requiring surgery sidelined him. He fully recovered from the operation, and NASA included him in the Apollo 11 crew. The Apollo 11 backup crew consisted of James A. Lovell, William A. Anders, and Fred W. Haise. Lovell and Anders had just completed the Apollo 8 lunar orbit mission with Haise a backup crew member on that flight. When Anders announced that he would retire from NASA in August 1969 to join the National Space Council, Thomas K. “Ken” Mattingly began training in parallel with Anders in case the mission slipped past that date.

Hardware began to arrive at KSC for Apollo 11. With the Apollo 10 CSM still undergoing testing in the MSOB, the Apollo 11 LM’s ascent and descent stages arrived Jan. 8 and 12, respectively, followed by the CM and SM on Jan. 23. Workers in the MSOB prepared the spacecraft for vacuum chamber testing. The Saturn V’s S-IVB third stage arrived on Jan. 19. Workers trucked it to the VAB where it awaited the arrival of the first two stages, scheduled for February.

With the Moon landing possibly just six months away, NASA continued to prepare key facilities designed to receive astronauts returning from the Moon. The 83,000-square-foot Lunar Receiving Laboratory (LRL), residing in MSC’s Building 37, was specially designed and built to isolate the astronauts, their spacecraft, and lunar samples to prevent back-contamination of the Earth by any possible lunar micro-organisms, and to maintain the lunar samples in as pristine a condition as possible. The building was completed in 1967, and over the next year, workers outfitted its laboratories and other facilities. A 10-day simulation in the facility in November 1968 found some deficiencies that NASA addressed promptly. On Jan. 23, 1969, workers brought a mockup Apollo CM into the LRL’s spacecraft storage area for fit checks.

Right: Workers in Norfolk load the MQF onto a C-141 cargo plane for the return flight to Ellington Air Force Base in Houston.

An integral component of the back-contamination prevention process was the Mobile Quarantine Facility (MQF). Following lunar landing missions, the MQF housed astronauts and support personnel from their arrival onboard the prime recovery ship shortly after splashdown through transport to the LRL. Under contract to NASA, Melpar, Inc., of Falls Church, Virginia, converted four 35-foot Airstream trailers into MQFs, delivering the first unit in March 1968 and the last three in the spring of 1969. The first unit was used extensively for testing, with lessons learned incorporated into the later models. On Jan. 21, 1969, workers loaded the MQF aboard a U.S. Air Force C-141 cargo plane at Ellington Air Force Base near MSC to transport it to the Norfolk Naval Air Station in Virginia. Six recovery specialists from MSC spent 10 days inside the MQF, first aboard the helicopter landing-platform USS Guadalcanal (LPH-7), including attaching a flexible tunnel to a boilerplate Apollo CM, and then aboard the destroyer USS Fox (DLG-33). The overall exercise, successfully completed on Feb. 3, tested all MQF systems aboard ships and aircraft to simulate recovery operations after a lunar landing mission.

To be continued …

      NASA Artemis II Moon Rocket Ready to Fly Crew
      By NASA
      NASA’s Artemis II SLS (Space Launch System) rocket poised to send four astronauts from Earth on a journey around the Moon next year may appear identical to the Artemis I SLS rocket. On closer inspection, though, engineers have upgraded the agency’s Moon rocket inside and out to improve performance, reliability, and safety.
      SLS flew a picture perfect first mission on the Artemis I test flight, meeting or exceeding parameters for performance, attitude control, and structural stability to an accuracy of tenths or hundredths of a percent as it sent an uncrewed Orion thousands of miles beyond the Moon. It also returned volumes of invaluable flight data for SLS engineers to analyze to drive improvements.
      Teams with NASA’s Exploration Ground Systems integrate the SLS (Space Launch System) Moon rocket with the solid rocket boosters onto mobile launcher 1 inside High Bay 3 of the Vehicle Assembly Building at NASA’s Kennedy Space Center in March 2025. Artemis II is the first crewed test flight under NASA’s Artemis campaign and is another step toward missions on the lunar surface and helping the agency prepare for future human missions to Mars.NASA/Frank Michaux For Artemis II, the major sections of SLS remain unchanged – a central core stage, four RS-25 main engines, two five-segment solid rocket boosters, the ICPS (interim cryogenic propulsion stage), a launch vehicle stage adapter to hold the ICPS, and an Orion stage adapter connecting SLS to the Orion spacecraft. The difference is in the details.
      “While we’re proud of our Artemis I performance, which validated our overall design, we’ve looked at how SLS can give our crews a better ride,” said John Honeycutt, NASA’s SLS Program manager. “Some of our changes respond to specific Artemis II mission requirements while others reflect ongoing analysis and testing, as well as lessons learned from Artemis I.”
      Engineers have outfitted the ICPS with optical targets that will serve as visual cues to the astronauts aboard Orion as they manually pilot Orion around the upper stage and practice maneuvers to inform docking operations for Artemis III.
      The Artemis II rocket includes an improved navigation system compared to Artemis I.  Its communications capability also has been improved by repositioning antennas on the rocket to ensure continuous communications with NASA ground stations and the U.S. Space Force’s Space Launch Delta 45 which controls launches along the Eastern Range.
      An emergency detection system on the ICPS allows the rocket to sense and respond to problems and notify the crew. The flight safety system adds a time delay to the self-destruct system to allow time for Orion’s escape system to pull the capsule to safety in event of an abort.
      The separation motors that push the solid rocket booster away after the elements are no longer needed were angled an additional 15 degrees to increase separation clearance as the rest of the rocket speeds by.
      Additionally, SLS will jettison the spent boosters four seconds earlier during Artemis II ascent than occurred during Artemis I. Dropping the boosters several seconds closer to the end of their burn will give engineers flight data to correlate with projections that shedding the boosters several seconds sooner will yield approximately 1,600 pounds of payload to Earth orbit for future SLS flights.
      Engineers have incorporated additional improvements based on lessons learned from Artemis I. During the Artemis I test flight the SLS rocket experienced higher-than-expected vibrations near the solid rocket booster attachment points that was caused by unsteady airflow.
      To steady the airflow, a pair of six-foot-long strakes flanking each booster’s forward connection points on the SLS intertank will smooth vibrations induced by airflow during ascent, and the rocket’s electronics system was requalified to endure higher levels of vibrations.
      Engineers updated the core stage power distribution control unit, mounted in the intertank, which controls power to the rocket’s other electronics and protects against electrical hazards.
      These improvements have led to an enhanced rocket to support crew as part of NASA’s Golden Age of innovation and exploration.
      The approximately 10-day Artemis II test flight is the first crewed flight under NASA’s Artemis campaign. It is another step toward new U.S.-crewed missions on the Moon’s surface that will help the agency prepare to send the first astronauts – Americans – to Mars.

      Weird Ways to Observe the Moon

      Weird Ways to Observe the Moon
      Sun Funnels in action! Starting clockwise from the bottom left, a standalone Sun Funnel; attached to a small refractor to observe the transit of Mercury in 2019; attached to a large telescope in preparation for evening lunar observing; projection of the Moon on a funnel from a medium-size scope (5 inches). Night Sky Network International Observe the Moon Night is on October 4, 2025, this year– but you can observe the Moon whenever it’s up, day or night! While binoculars and telescopes certainly reveal incredible details of our neighbor’s surface, bringing out dark seas, bright craters, and numerous odd fissures and cracks, these tools are not the only way to observe details about our Moon. There are more ways to observe the Moon than you might expect, just using common household materials.
      Put on a pair of sunglasses, especially polarized sunglasses! You may think this is a joke, but the point of polarized sunglasses is to dramatically reduce glare, and so they allow your eyes to pick out some lunar details! Surprisingly, wearing sunglasses even helps during daytime observations of the Moon.
      One unlikely tool is the humble plastic bottle cap! John Goss from the Roanoke Valley Astronomical Society shared these directions on how to make your own bottle cap lunar viewer, which was suggested to him by Fred Schaaf many years ago as a way to also view the thin crescent of Venus when close to the Sun:
      “The full Moon is very bright, so much that details are overwhelmed by the glare. Here is an easy way to see more! Start by drilling a 1/16-inch (1.5 mm) diameter hole in a plastic soft drink bottle cap. Make sure it is an unobstructed, round hole.  Now look through the hole at the bright Moon. The image brightness will be much dimmer than normal – over 90% dimmer – reducing or eliminating any lunar glare. The image should also be much sharper because the bottle cap blocks light from entering the outer portion of your pupil, where imperfections of the eye’s curving optical path likely lie.” Many report seeing a startling amount of lunar detail!
      You can project the Moon! Have you heard of a “Sun Funnel”? It’s a way to safely view the Sun by projecting the image from an eyepiece to fabric stretched across a funnel mounted on top. It’s easy to make at home, too – directions are here: bit.ly/sunfunnel. Depending on your equipment, a Sun Funnel can view the Moon as well as the Sun– a full Moon gives off more than enough light to project from even relatively small telescopes. Large telescopes will project the full Moon and its phases with varying levels of detail; while not as crisp as direct eyepiece viewing, it’s still an impressive sight! You can also mount your smartphone or tablet to your eyepiece for a similar Moon-viewing experience, but the funnel doesn’t need batteries.
      Of course, you can join folks in person or online to celebrate our Moon on October 4, 2025, with International Observe the Moon Night – find details at moon.nasa.gov/observe.
