In September 1969, celebrations continued to mark the successful first human Moon landing two months earlier, and NASA prepared for the next visit to the Moon. The hometowns of the Apollo 11 astronauts held parades in their honor, the postal service recognized their accomplishment with a stamp, and the Smithsonian put a Moon rock on display. They addressed Congress and embarked on a 38-day presidential round the world goodwill tour. Eager scientists received the first samples of lunar material to study in their laboratories. Meanwhile, NASA prepared Apollo 12 for November launch as the astronauts trained for the mission with an increased emphasis on lunar science. Plans called for additional Moon landings in 1970, with spacecraft under construction and astronauts in training.

Apollo 11

For Apollo 11 astronauts Neil A. Armstrong, Michael Collins, and Edwin E. “Buzz” Aldrin, their busy August 1969 postflight schedule continued into September with events throughout the United States and beyond. These included attending hometown parades, dedicating a stamp to commemorate their historic mission, unveiling a display of a Moon rock they collected, addressing a Joint Meeting of Congress, and visiting contractor facilities that built parts of their rocket and spacecraft. They capped off the hectic month with their departure, accompanied by their wives, on a presidential round-the-world goodwill tour that lasted into early November.

On Sep. 6, each astronaut appeared at hometown events held in their honor. Apollo 11 Commander Armstrong’s hometown of Wapakoneta, Ohio, welcomed him with a parade and other events.  Montclair, New Jersey, held a parade to honor hometown hero Lunar Module Pilot (LMP) Aldrin. And New Orleans, Louisiana, the adopted hometown of Command Module Pilot (CMP) Michael Collins, honored him with a parade.

Three days later, the astronauts reunited in Washington, D.C., where they appeared at the dedication ceremony of a new postage stamp that honored their mission. The U.S. Postal Service had commissioned artist Paul Calle in 1968 to design the stamp. The Apollo 11 astronauts had carried the stamp’s master die to the Moon aboard the Lunar Module (LM) Eagle and after its return to Earth the Postal Service used it to make the printing pages for the 10¢ postage stamp. At the National Postal Forum, Armstrong, Collins, and Aldrin unveiled the stamp together with Postmaster General Winton M. Blount, and each astronaut received an album with 30 of the “First Man on the Moon” stamps. On Sep. 15, the crew returned to Washington to present a two-pound rock they collected in the Sea of Tranquility during their historic Moon walk to Frank A. Taylor, the Director General of Museums at the Smithsonian Institution in Washington, D.C. The rock went on public display two days later at the Smithsonian’s Arts and Industries Building, the first time the public could view a Moon rock.

Right: The Apollo 11 astronauts and their wives cut at a cake at a reception at the Capitol.

With their wives observing from the Visitors Gallery of the House of Representatives, on Sep. 16 Armstrong, Aldrin, and Collins addressed a Joint Meeting of Congress. In this same chamber in May 1961, President John F. Kennedy committed the nation to land a man on the Moon and return him safely to the Earth before the end of decade. In a sense, the astronauts reported on the safe and successful completion of that challenge. Speaker of the House John W. McCormack introduced the astronauts to the gathering, as Vice President Spiro T. Agnew looked on. Each astronaut reflected on the significance of the historic mission.

Armstrong noted that their journey truly began in the halls of Congress when the Space Act of 1958 established NASA. Aldrin commented that “the Apollo lesson is that national goals can be met when there is a strong enough will to do so.” Collins shared a favorite quotation of his father’s to describe the value of the Apollo 11 mission: “He who would bring back the wealth of the Indies must take the wealth of the Indies with him.” Armstrong closed with, “We thank you, on behalf of all the men of Apollo, for giving us the privilege of joining you in serving – for all mankind.” After their speeches, the astronauts presented one American flag each to Vice President Agnew in his role as President of the Senate and to Speaker McCormack. The flags, that had flown over the Senate and House of Representatives, had traveled to the Moon and back with the astronauts. Speaker McCormack recognized the astronauts’ wives Jan Armstrong, Joan Aldrin, and Pat Collins for their contributions to the success of the Apollo 11 mission.

On Sep. 26, Armstrong and Collins visited two facilities in California of North American Rockwell (NAR) Space Division, the company that built parts of the Saturn V rocket and Apollo 11 spacecraft. First, they stopped at the Seal Beach plant that built the S-II second stage of the rocket, where 3,000 employees turned out to welcome them. Armstrong commented to the assembled crowd that during the July 16, 1969, liftoff, “the S-II gave us the smoothest ride ever.” Collins added that despite earlier misgivings about using liquid hydrogen as a rocket fuel, “after the ride you people gave us, I sure don’t have doubts any longer.” About 7,000 employees greeted the two astronauts and showered them with confetti at their next stop, the facility in Downey that built the Apollo Command and Service Modules. Both Armstrong and Collins thanked the team for building an outstanding spacecraft that took them to the Moon and returned them safely to Earth. The astronauts inspected the Command Module (CM) for Apollo 14, then under construction at the plant.

On the morning of Sep. 29, a blue and white Boeing VC-137B presidential jet touched down at Ellington Air Force Base in Houston. Neil and Jan Armstrong, Buzz and Joan Aldrin, and Mike and Pat Collins boarded the plane and joined their entourage of State Department and NASA support personnel. They departed Houston for Mexico City, the first stop on the Apollo 11 Giantstep goodwill world tour. They didn’t return to the United States until Nov. 5, having visited 29 cities in 24 countries, just nine days before Apollo 12 took off on humanity’s second journey to land on the Moon.

Back in Houston, distribution to scientists of samples of the lunar material returned by the Apollo 11 astronauts began on Sep. 17 at the Lunar Receiving Laboratory (LRL) at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston. Daniel H. Anderson, curator of lunar samples at the LRL, supervised the distribution of approximately 18 pounds – about one-third of the total Apollo 11 lunar material – to 142 principal investigators from the United States and eight other countries according to prior agreements. The scientists examined the samples at their home institutions and reported their results at a conference in Houston in January 1970. They returned to the LRL any of the samples not destroyed during the examination process.

Apollo 12

In September 1969, NASA continued preparations for the second Moon landing mission, Apollo 12, scheduled for launch on Nov. 14. The Apollo 12 mission called for a pinpoint landing in Oceanus Procellarum (Ocean of Storms) near where the robotic spacecraft Surveyor 3 had touched down in April 1967. They planned to stay on the lunar surface for about 32 hours, compared to Apollo 11’s 21 hours, and conduct two surface spacewalks totaling more than 5 hours. During the first of their two excursions, the astronauts planned to deploy the Apollo Lunar Surface Experiments Package (ALSEP) and collect lunar samples. During the second spacewalk, they planned to visit Surveyor 3 and remove some of its equipment for return to Earth and collect additional lunar samples. The Apollo 12 prime crew of Commander Charles “Pete” Conrad, CMP Richard F. Gordon, and LMP Alan L. Bean and their backups David R. Scott, Alfred M. Worden, and James B. Irwin continued intensive training for the mission.

Right: Apollo 12 astronauts Alan L. Bean, left, Richard F. Gordon, and Charles “Pete” Conrad pose in front of their Saturn V during the rollout to the pad.

On Sep. 8, the Saturn V rocket with the Apollo 12 spacecraft on top rolled out from Kennedy Space Center’s (KSC) Vehicle Assembly Building to Launch Pad 39A. The rocket made the 3.5-mile trip to the pad in about 6 hours, with Conrad, Gordon, and Bean on hand to observe the rollout. Workers at the pad spent the next two months thoroughly checking out the rocket and spacecraft to prepare it for its mission to the Moon. The two-day Flight Readiness Test at the end of September ensured that the launch vehicle and spacecraft systems were in a state of flight readiness. In addition to spending many hours in the spacecraft simulators, Conrad and Bean as well as their backups Scott and Irwin rehearsed their lunar surface spacewalks including the visit to Surveyor 3. Workers at NASA’s Jet Propulsion Laboratory in Pasadena, California, shipped an engineering model of the robotic spacecraft to KSC, and for added realism, engineers there mounted the model on a slope to match its relative position on the interior of the crater in which it stood on the Moon. Conrad and Scott used the Lunar Landing Training Vehicle (LLTV) at Ellington Air Force Base (AFB) near MSC to train for the final 200 feet of the descent to the lunar surface.

With regard to lunar geology training, the Apollo 12 astronauts had one advantage over their predecessors – they could inspect actual Moon rocks and soil returned by the Apollo 11 crew. On Sep. 19, Conrad and Bean arrived at the LRL, where Lunar Sample Curator Anderson met them. Anderson brought out a few lunar rocks and some lunar soil that scientists had already tested and didn’t require to be stored under vacuum or other special conditions, allowing Conrad and Bean to examine them closely and compare them with terrestrial rocks and soil they had seen during geology training field trips. This first-hand exposure to actual lunar samples significantly augmented Conrad and Bean’s geology training. To highlight the greater emphasis placed on lunar surface science, the Apollo 12 crews (prime and backup) went on six geology field trips compared to just one for the Apollo 11 crews.

Although the Apollo 11 astronauts returned from the Moon in excellent health and scientists found no evidence of any harmful lunar microorganisms, NASA managers still planned to continue the postflight quarantine program for the Apollo 12 crew members, their spacecraft, and the lunar samples they brought back. The first of these measures involved the astronauts donning Biological Isolation Garments (BIG) prior to exiting the spacecraft after splashdown. Since they didn’t carry the BIGs with them to the Moon and back, one of the recovery personnel, also clad in a BIG, opened the hatch to the capsule after splashdown and handed the suits to the astronauts inside, who donned them before exiting onto a life raft.

On Sep. 20, the Apollo 12 astronauts rehearsed these procedures, identical to the ones used after the first Moon landing mission, in the Gulf of Mexico near Galveston, Texas, using a boilerplate Apollo CM and supported by the Motorized Vessel (MV) Retriever. As it turned out, NASA later removed the requirement for the crew to wear BIGs, and after their splashdown the Apollo 12 crew wore overalls and respirators.

Preparations for Apollo 13 continued in parallel. In KSC’s Manned Spacecraft Operations Building (MSOB), Apollo 13 astronauts completed altitude chamber tests of their mission’s CM and LM. Prime crew members Commander James A. Lovell, CMP Thomas K. “Ken” Mattingly, and LMP Fred W. Haise completed the CM altitude test on Sep. 10, followed by their backups John W. Young, Jack L. Swigert, and Charles M. Duke on Sep. 17. The next day, Lovell and Haise completed the altitude test of the LM, followed by Young and Duke on Sep. 22. At the time of these tests, Apollo 13 planned to launch on March 12, 1970, on a 10-day mission to visit the Fra Mauro highlands region of the Moon. To prepare for their lunar surface excursions, Lovell, Haise, Young, and Duke, accompanied by geologist-astronaut Harrison H. “Jack” Schmitt and Caltech geologist Leon T. “Lee” Silver, spent the last week of September in Southern California’s Orocopia Mountains immersed in a geology boot camp.

Looking beyond Apollo 13, the Apollo 14 crew of Commander Alan B. Shepard, CMP Stuart A. Roosa, and LMP Edgar D. Mitchell and their backups Eugene A. Cernan, Ronald E. Evans, and Joe H. Engle had started training for their mission planned for mid-year 1970. At the NAR facility in Downey, engineers prepared the CM and SM and shipped them to KSC in November 1969. Also at Downey, workers continued assembling the CM and SM planned for the Apollo 15 mission in late 1970. As events transpired throughout 1970, plans for those two missions changed significantly.

On Sept. 25, NASA appointed veteran astronaut James A. McDivitt as the Manager of the Apollo Spacecraft Program Office at MSC. McDivitt, selected as an astronaut in 1962, commanded two spaceflights, Gemini IV in June 1965 that included the first American spacewalk and Apollo 9 in March 1969, the first test of the LM in Earth orbit. He succeeded George M. Low who, in that position since April 1967, led the agency’s efforts to recover from the Apollo 1 fire and originated the idea to send Apollo 8 on a lunar orbital mission. Under his tenure, NASA successfully completed five crewed Apollo missions including the first human Moon landing. MSC Director Robert R. Gilruth initially assigned Low to plan future programs until Nov. 13, when President Richard M. Nixon nominated him as NASA deputy administrator. The Senate confirmed Low’s nomination on Nov. 25, and NASA Administrator Thomas O. Paine swore him in on Dec. 3. Low filled the position vacant since March 20, 1969.

      On Jan. 9, 1990, space shuttle Columbia took off on its ninth flight, STS-32, from NASA’s Kennedy Space Center (KSC) in Florida. Its five-person crew of Commander Daniel Brandenstein, Pilot James Wetherbee, and Mission Specialists Bonnie Dunbar, Marsha Ivins, and David Low flew a then record-breaking 11-day mission to deploy the Syncom IV-F5 communications satellite for the U.S. Navy and retrieve the Long-Duration Exposure Facility (LDEF). Astronauts aboard a shuttle mission in 1984 deployed the LDEF and scientists eagerly awaited the return of their 57 experiments to study the effects of nearly six years exposure to the low Earth orbit environment. The crew also conducted several middeck experiments in biotechnology and materials processing and used an echocardiograph to study changes in their hearts.

The Long Duration Exposure Facility during its deployment on the STS-41C mission in 1984.  In November 1988, NASA announced Brandenstein, Wetherbee, Dunbar, Ivins, and Low as the STS-32 crew for the flight then planned for November 1989. Brandenstein, from the Class of 1978, had flown twice before, as pilot on STS-8 in August-September 1983 and commander of STS-51G in June 1985. Dunbar, selected in 1980, had flown once before on STS-61A in October-November 1985. For Wetherbee, Ivins, and Low, all selected in 1984, STS-32 marked their first spaceflight. During the second day of their planned 10-day mission, the astronauts would deploy the Syncom IV-F5, also known as Leasat-5, communications satellite for the U.S. Navy. The main focus of the flight involved the retrieval of LDEF, deployed by the STS-41C crew in April 1984. The original plan had LDEF, containing 57 science and technology experiments, retrieved by the STS-51D crew in February 1985. Delays in the shuttle program first pushed the retrieval to STS-61I in September 1986, and then the Challenger accident delayed it to STS-32. The facility ended up staying in orbit nearly six years instead of the originally intended 10 months. The crew rounded out the mission by conducting a series of middeck science and medical experiments.

NASA scientist John Charles, at rear, trains astronauts David Low, left, and Bonnie Dunbar, supine, in the operation of a cardiovascular experiment. The STS-32 crew exits crew quarters for the ride to Launch Pad 39A. Columbia returned to KSC on Aug. 21, 1989, following STS-28’s landing at Edwards Air Force Base (AFB) in California, and workers towed it to the Orbiter Processing Facility (OPF) the next day. They made 26 modifications to the orbiter, including the installation of the Remote Manipulator System (RMS), or robotic arm, and a fifth set of liquid hydrogen and liquid oxygen tanks to extend the vehicle’s duration in space. Rollover to the nearby Vehicle Assembly Building took place on Nov. 16, where Columbia joined its External Tank and twin Solid Rocket Boosters (SRB) on refurbished Mobile Launch Platform 3, last used in 1975. Rollout took place on Nov. 28 to Launch Pad 39A, newly refurbished since its previous launch in 1986.  
      On Dec. 1, engineers and the astronaut crew completed the Terminal Countdown Demonstration Test, a dress rehearsal for the planned Dec. 18 launch. Based on that date and the mission’s planned 10-day duration, the STS-32 crew would have spent Christmas in space, only the third American crew and the first space shuttle crew to do so. However, unfinished work on Pad 39A delayed the launch into January 1990. Trajectory specialists had estimated that due to orbital decay, LDEF would reenter the Earth’s atmosphere by March 1990, so a timely launch remained crucial for mission success. The countdown began on Jan. 4 for an expected Jan. 8 launch, with the crew arriving at KSC on Jan. 5.

Liftoff took place the next day at 7:35 a.m. EST from Launch Pad 39A, with LDEF 1,500 miles ahead of Columbia. The powered ride to space took 8.5 minutes, placing Columbia into a 215-by-38-mile orbit. A burn of the two Orbiter Maneuvering System (OMS) engines 40 minutes later changed the orbit to the desired 222-by-180-mile altitude. The crew opened the shuttle’s payload bay doors and deployed its radiators. The major activities for the first day in space involved the checkout of the RMS and the first rendezvous maneuver in preparation for the LDEF grapple three days later. The astronauts also activated four of the middeck experiments. On the mission’s second day, Low deployed the 15,000-pound Syncom satellite, releasing it in a frisbee motion out of the payload bay. The satellite extended its antenna, stabilized itself, and 40 minutes after deployment, fired its engine for the first burn to send it to its geostationary orbit.

Following the Syncom deploy, the crew turned its attention to the rendezvous with LDEF while also continuing the middeck experiments. On Flight Day 3, they completed three rendezvous burns as they steadily continued their approach to LDEF. Soon after awakening on Flight Day 4, the astronauts spotted LDEF appearing as a bright star. After the first of four rendezvous burns, Columbia’s radar locked onto the satellite. As they continued the approach, with three more burns carried out successfully, Dunbar activated the RMS in preparation for the upcoming grapple. Brandenstein took over manual control of Columbia for the final approach and parked the shuttle close enough to LDEF for Dunbar to reach out with the 50-foot arm and grapple the satellite. Brandenstein reported, “We have LDEF.”  
      For the next four hours, with Wetherbee flying the orbiter and Dunbar operating the arm, Ivins performed a comprehensive photo survey of LDEF, documenting the effects of nearly six years of space exposure on the various experiments. The survey completed, Dunbar slowly and carefully lowered LDEF into the payload bay, and five latches secured it in place for the ride back to Earth. With the two major goals of their mission completed, the astronauts settled down for the remainder of their 10-day mission conducting science experiments. 

      With astronaut David Low acting as an operator, astronaut Bonnie Dunbar serves as a subject for a cardiovascular experiment. Astronaut Marsha Ivins with several cameras testing the effects of spaceflight on different types of film. During the mission, the STS-32 crew conducted several middeck experiments. The Protein Crystal Growth experiment used vapor diffusion to grow 120 crystals of 24 different proteins, for study by scientists following their return to Earth. The Characterization of Neurospora Circadian Rhythm experiment studied whether spaceflight affected the daily cycles of pink bread mold. The Fluid Experiment Apparatus performed materials processing research in the microgravity environment. The astronauts used the American Flight Echocardiograph (AFE) to study changes in their hearts as a result of weightlessness. The crew used the large format IMAX camera to film scenes inside the cabin as well as through the windows, such as the capture of LDEF. 

      Astronaut Daniel Brandenstein holds an inflatable plastic cake given to him by his crew mates in honor of his birthday. The STS-32 crew poses in Columbia’s middeck. On Jan. 17, Brandenstein celebrated his 47th birthday, the fifth American astronaut to do so in space. His crew presented him with an inflatable plastic cake including candles while controllers in Mission Control passed on their birthday wishes as did his wife and teenage daughter. On the same day, NASA announced the selection of its 13th group of astronauts. Among them, engineer Ronald Sega, Dunbar’s husband, as well as the first female shuttle pilot, Eileen Collins, and the first Hispanic woman astronaut, Ellen Ochoa. 

      Columbia touches down at Edwards Air Force Base in California. At the welcome home ceremony at Ellington Field in Houston, director of NASA’s Johnson Space Center Aaron Cohen addresses the crowd as the STS-32 astronauts and their families listen. On Jan. 19, the astronauts awakened for their planned final day in space. However, due to fog at their landing site, Edwards AFB in California, Mission Control first informed them that they would have to spend an extra orbit in space, and finally decided to delay the landing by an entire day. With their experiments already packed, the crew spent a quiet day, looking at the Earth and using up what film still remained. As they slept that night, they passed the record for the longest space shuttle mission, set by STS-9 in 1983.  
      In preparation for reentry, the astronauts donned their orange spacesuits and closed the payload bay doors. A last-minute computer problem delayed reentry by one orbit, then Brandenstein and Wetherbee oriented Columbia into the deorbit attitude, with the OMS engines facing in the direction of travel. Over the Indian Ocean, they fired the two engines for 2 minutes 48 seconds to bring the spacecraft out of orbit. They reoriented the orbiter to fly with its heat shield exposed to the direction of flight as it encountered Earth’s atmosphere at 419,000 feet. The buildup of ionized gases caused by the heat of reentry prevented communications for about 15 minutes but provided the astronauts a great light show. After completing the Heading Alignment Circle turn, Brandenstein aligned Columbia with the runway, and Wetherbee lowered the landing gear. Columbia touched down and rolled to a stop, making the third night landing of the shuttle program and ending a 10-day 21-hour 1-minute flight, the longest shuttle flight up to that time, having completed 172 orbits of the Earth.  
      Other records set by the astronauts on this mission included Brandenstein as the new record holder for most time spent in space by a shuttle crew member – 24 days – and Dunbar accumulating the most time in space by a woman – 18 days – up to that time. Following eight hours of postflight medical testing, the astronauts boarded a jet bound for Houston’s Ellington Field, where they reunited with their families and took part in a welcome home ceremony led by Aaron Cohen, director of NASA’s Johnson Space Center. 

      Columbia returns to NASA’s Kennedy Space Center in Florida atop the Shuttle Carrier Aircraft. Workers lift the Long Duration Exposure Facility from Columbia’s payload bay. Following postlanding inspections, workers placed Columbia, with LDEF still cradled in its payload bay, atop a Shuttle Carrier Aircraft, a modified Boeing-747, and the combination left Edwards on Jan. 25. Following a refueling stop at Monthan Davis AFB in Tucson, an overnight stay at Kelly AFB in San Antonio, and another refueling stop at Eglin AFB in Fort Walton Beach, Florida, Columbia and LDEF arrived back at KSC on Jan. 26. The next day, workers towed Columbia to the OPF and on Jan. 30 lifted LDEF out of its payload bay, in preparation for the detailed study of the effects of nearly six years in space on the 57 experiments it carried. Meanwhile, workers began to prepare Columbia for its next flight, STS-35 in December 1990.

      Inside of the Electrostatics and Surface Physics Laboratory at NASA’s Kennedy Space Center in Florida, an electrodynamic dust shield (EDS) is in view on Jan. 18, 2023. The dust shield is one of the payloads that will fly aboard Firefly Aerospace’s Blue Ghost lunar lander as part of NASA’s Commercial Lunar Payload Services (CLPS) initiative. NASA/Cory Huston Defeating dust may be a small concern for most people on Earth, but for astronauts and spacecraft destined for the Moon or Mars, it is a significant hazard that must be mitigated. That’s why researchers at NASA’s Kennedy Space Center in Florida are seeking innovative ways to use the Electrodynamic Dust Shield (EDS) technology.  
      The EDS technology is headed to the Moon as part of the agency’s Artemis campaign. This innovative technology will be demonstrated on the lunar surface, where it will use electrical forces to lift and remove lunar regolith, or dirt, from various surfaces.
      This dust-mitigating technology is one of 10 payloads aboard the next lunar delivery through NASA’s CLPS (Commercial Lunar Payload Services) initiative, set to launch from the agency’s Kennedy Space Center in Florida Wednesday, Jan. 15, with Firefly Aerospace’s Blue Ghost Lander.
      Using transparent electrodes and electric fields, EDS technology can lift and remove dust from a variety of surfaces for space applications ranging from thermal radiators, solar panels, and camera lenses to spacesuits, boots, and helmet visors. Controlling and removing the charged dust will be critical to the success of Moon missions under the agency’s CLPS initiative and Artemis campaign.  
      “For these CLPS and Artemis missions, dust exposure is a concern because the lunar surface is far different than what we’re used to here,” said Dr. Charles Buhler, lead research scientist at the Electrostatics and Surface Physics Laboratory at Kennedy. “Lunar regolith dust can get into gaskets and seals, into hatches, and even into habitats, which can pose a lot of issues for spacecraft and astronauts.”  
      Unlike dust particles on Earth, dust on the Moon’s surface is sharp and abrasive – like tiny shards of glass – because it hasn’t been exposed to weathering and elements like water and oxygen.  
      “Simply brushing lunar regolith across surfaces can make the problem worse because it’s also very electrostatically charged and highly insulating,” Buhler said.  
      Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA aims to be one of many customers on future flights. EDS was funded by the Space Technology Mission Directorate (STMD) Game Changing Development Program (GCD).

      On Jan. 7, 1610, Italian astronomer Galileo Galilei peered through his newly improved 20-power homemade telescope at the planet Jupiter. He noticed three other points of light near the planet, at first believing them to be distant stars. Observing them over several nights, he noted that they appeared to move in the wrong direction with regard to the background stars and they remained in Jupiter’s proximity but changed their positions relative to one another. Four days later, he observed a fourth point of light near the planet with the same unusual behavior. By Jan. 15, Galileo correctly concluded that he had discovered four moons orbiting around Jupiter, providing strong evidence for the Copernican theory that most celestial objects did not revolve around the Earth.

Painting by Giuseppe Bertini (1858) of Galileo demonstrating his telescope to the Doge of Venice.gabrielevanin.it Page from Galileo’s notebook about his observations of Jupiter’s satellites.University of Michigan Special Collections Library. In March 1610, Galileo published his discoveries of Jupiter’s satellites and other celestial observations in a book titled Siderius Nuncius (The Starry Messenger). As their discoverer, Galileo had naming rights to Jupiter’s satellites. He proposed to name them after his patrons the Medicis and astronomers called them the Medicean Stars through much of the seventeenth century, although in his own notes Galileo referred to them by the Roman numerals I, II, III, and IV, in order of their distance from Jupiter. Astronomers still refer to the four moons as the Galilean satellites in honor of their discoverer.  

      In 1614, the German astronomer Johannes Kepler suggested naming the satellites after mythological figures associated with Jupiter, namely Io, Europa, Ganymede, and Callisto, but his idea didn’t catch on for more than 200 years. Scientists didn’t discover any more satellites around Jupiter until 1892 when American astronomer E.E. Barnard found Jupiter’s fifth moon Amalthea, much smaller than the Galilean moons and orbiting closer to the planet than Io. It was the last satellite in the solar system found by visual observation – all subsequent discoveries occurred via photography or digital imaging. As of today, astronomers have identified 95 moons orbiting Jupiter.

Hubble Space Telescope image of Jupiter and three of its four Galilean satellites during a rare triple transit. Although each of the Galilean satellites has unique features, such as the volcanoes of Io, the heavily cratered surface of Callisto, and the magnetic field of Ganymede, scientists have focused more attention on Europa due to the tantalizing possibility that it might be hospitable to life. In the 1970s, NASA’s Pioneer 10 and 11 and Voyager 1 and 2 spacecraft took ever increasingly detailed images of the large satellites including Europa during their flybys of Jupiter. The photographs revealed Europa to have the smoothest surface of any object in the solar system, indicating a relatively young crust, and also one of the brightest of any satellite indicating a highly reflective surface. These features led scientists to hypothesize that Europa is covered by an icy crust floating on a subsurface salty ocean. They further postulated that tidal heating caused by Jupiter’s gravity reforms the surface ice layer in cycles of melting and freezing.

Image of Europa taken by Voyager 2 during its 1979 flyby of Jupiter. More detailed observations from NASA’s Galileo spacecraft that orbited Jupiter between 1995 and 2003 and completed 11 close encounters with Europa revealed that long linear features on its surface may indicate tidal or tectonic activity. Reddish-brown material along the fissures and in splotches elsewhere on the surface may contain salts and sulfur compounds transported from below the crust and modified by radiation. Observations from the Hubble Space Telescope and re-analysis of images from Galileo revealed possible plumes emanating from beneath Europa’s crust, lending credence to that hypothesis. While the exact composition of this material is not known, it likely holds clues to whether Europa may be hospitable to life.

Cutaway illustration of Europa’s icy crust, subsurface ocean and possible vents that transport material to the surface. Future robotic explorers of Europa may answer some of the outstanding questions about this unique satellite of Jupiter. NASA’s Europa Clipper set off in October 2024 on a 5.5-year journey to Jupiter. After its arrival in 2030, the spacecraft will enter orbit around the giant planet and conduct 49 flybys of Europa during its four-year mission. Managed by the Jet Propulsion Laboratory in Pasadena, California, and the Applied Physics Laboratory at Johns Hopkins University in Baltimore, Maryland, Europa Clipper will carry nine instruments including imaging systems and a radar to better understand the structure of the icy crust. Data from Europa Clipper will complement information returned by the European Space Agency’s JUICE (Jupiter Icy Moon Explorer) spacecraft. Launched in April 2023, JUICE will first enter orbit around Jupiter in 2031 and then enter orbit around Ganymede in 2034. The spacecraft also plans to conduct studies of Europa complementary with Europa Clipper’s. The two spacecraft should greatly increase our understanding of Europa and perhaps uncover new mysteries.
