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.

Blount display an enlargement of the stamp commemorating the first Moon landing. Right: Aldrin, left, Collins, and Armstrong examine a Moon rock with Smithsonian Institution Director General of Museums Frank A. Taylor.
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.
Distribution of Apollo 11 lunar samples to scientists at the Lunar Receiving Laboratory at the Manned Spacecraft Center, now NASA’s Johnson Space Center in Houston.
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.

Middle: Conrad trains in the use of the Hasselblad camera he and Bean will use on the Moon. Right: Bean, left, and Conrad train with an engineering model of a Surveyor spacecraft.
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.
Apollo 13

Haise is out of the picture at right – at NASA’s Kennedy Space Center in Florida. Middle: Apollo 13 backup astronaut John L. “Jack” Swigert prepares to enter the CM for an altitude chamber test. Right: Apollo 13 backup crew members John W. Young, left, and Swigert in the CM for an altitude chamber test – Charles M. Duke is out of the picture at right.
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.
Apollo 14 and 15

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.
NASA management changes

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.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
While astronaut Gene Cernan was on the lunar surface during the Apollo 17 mission, his spacesuit collected loads of lunar dust. The gray, powdery substance stuck to the fabric and entered the capsule causing eye, nose, and throat irritation dubbed “lunar hay fever.” Credit: NASACredit: NASA Moon dust, or regolith, isn’t like the particles on Earth that collect on bookshelves or tabletops – it’s abrasive and it clings to everything. Throughout NASA’s Apollo missions to the Moon, regolith posed a challenge to astronauts and valuable space hardware.
During the Apollo 17 mission, astronaut Harrison Schmitt described his reaction to breathing in the dust as “lunar hay fever,” experiencing sneezing, watery eyes, and a sore throat. The symptoms went away, but concern for human health is a driving force behind NASA’s extensive research into all forms of lunar soil.
The need to manage the dust to protect astronaut health and critical technology is already beneficial on Earth in the fight against air pollution.
Working as a contributor on a habitat for NASA’s Next Space Technologies for Exploration Partnerships (NextSTEP) program, Lunar Outpost Inc. developed an air-quality sensor system to detect and measure the amount of lunar soil in the air that also detects pollutants on Earth.
Originally based in Denver, the Golden, Colorado-based company developed an air-quality sensor called the Space Canary and offered the sensor to Lockheed Martin Space for its NextSTEP lunar orbit habitat prototype. After the device was integrated into the habitat’s environmental control system, it provided distinct advantages over traditional equipment.
Rebranded as Canary-S (Solar), the sensor is now meeting a need for low-cost, wireless air-quality and meteorological monitoring on Earth. The self-contained unit, powered by solar energy and a battery, transmits data using cellular technology. It can measure a variety of pollutants, including particulate matter, carbon monoxide, methane, sulfur dioxide, and volatile organic compounds, among others. The device sends a message up to a secure cloud every minute, where it’s routed to either Lunar Outpost’s web-based dashboard or a customer’s database for viewing and analysis.
The oil and gas industry uses the Canary-S sensors to provide continuous, real-time monitoring of fugitive gas emissions, and the U.S. Forest Service uses them to monitor forest-fire emissions.
“Firefighters have been exhibiting symptoms of carbon monoxide poisoning for decades. They thought it was just part of the job,” explained Julian Cyrus, chief operating officer of Lunar Outpost. “But the sensors revealed where and when carbon monoxide levels were sky high, making it possible to issue warnings for firefighters to take precautions.”
The Canary-S sensors exemplify the life-saving technologies that can come from the collaboration of NASA and industry innovations.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
This artist’s concept depicts NASA’s Europa Clipper spacecraft in orbit around Jupiter. The mission is targeting an Oct. 10, 2024, launch.NASA/JPL-Caltech The first NASA spacecraft dedicated to studying an ocean world beyond Earth, Europa Clipper aims to find out if the ice-encased moon Europa could be habitable.
NASA’s Europa Clipper spacecraft, the largest the agency has ever built for a planetary mission, will travel 1.8 billion miles (2.9 billion kilometers) from the agency’s Kennedy Space Center in Florida to Europa, an intriguing icy moon of Jupiter. The spacecraft’s launch period opens Thursday, Oct. 10.
Learn more about how NASA’s Europa Clipper came together – and how it will explore an ocean moon of Jupiter. Credit: NASA/JPL-Caltech Data from previous NASA missions has provided scientists with strong evidence that an enormous salty ocean lies underneath the frozen surface of the moon. Europa Clipper will orbit Jupiter and conduct 49 close flybys of the moon to gather data needed to determine whether there are places below its thick frozen crust that could support life.
Here are eight things to know about the mission:
1. Europa is one of the most promising places to look for currently habitable conditions beyond Earth.
There’s scientific evidence that the ingredients for life — water, the right chemistry, and energy — may exist at Europa right now. This mission will gather the information scientists need to find out for sure. The moon may hold an internal ocean with twice the water of Earth’s oceans combined, and it may also host organic compounds and energy sources under its surface. If the mission determines that Europa is habitable, it would mean there may be more habitable worlds in our solar system and beyond than we have imagined.
2. The spacecraft will fly through one of the most punishing radiation environments in our solar system — second only to the Sun’s.
Jupiter is surrounded by a gigantic magnetic field 20,000 times stronger than Earth’s. As the field spins, it captures and accelerates charged particles, creating radiation that can damage spacecraft. Mission engineers designed a spacecraft vault to shield sensitive electronics from radiation, and they plotted orbits that will limit the time Europa Clipper spends in most radiation-heavy areas around Jupiter.
3. Europa Clipper will orbit Jupiter, studying Europa while flying by the moon dozens of times.
The spacecraft will make looping orbits around Jupiter that bring it close to Europa for 49 science-dedicated flybys. On each orbit, the spacecraft will spend less than a day in Jupiter’s dangerous radiation zone near Europa before zipping back out. Two to three weeks later, it will repeat the process, making another flyby.
4. Europa Clipper features NASA’s most sophisticated suite of science instruments yet.
To determine if Europa is habitable, Europa Clipper must assess the moon’s interior, composition, and geology. The spacecraft carries nine science instruments and a gravity experiment that uses the telecommunications system. In order to obtain the best science during each flyby, all the science instruments will operate simultaneously on every pass. Scientists will then layer the data together to paint a full picture of the moon.
5. With antennas and solar arrays fully deployed, Europa Clipper is the largest spacecraft NASA has ever developed for a planetary mission.
The spacecraft extends 100 feet (30.5 meters) from one end to the other and about 58 feet (17.6 meters) across. That’s bigger than a basketball court, thanks in large part to the solar arrays, which need to be huge so they can collect enough sunlight while near Jupiter to power the instruments, electronics, and other subsystems.
6. It’s a long journey to Jupiter.
Jupiter is on average some 480 million miles (about 770 million kilometers) from Earth; both planets are in motion, and a spacecraft can carry only a limited amount of fuel. Mission planners are sending Europa Clipper past Mars and then Earth, using the planets’ gravity as a slingshot to add speed to the spacecraft’s trek. After journeying about 1.8 billion miles (2.9 billion kilometers) over 5½ years, the spacecraft will fire its engines to enter orbit around Jupiter in 2030.
7. Institutions across the U.S. and Europe have contributed to Europa Clipper.
Currently, about a thousand people work on the mission, including more than 220 scientists from both the U.S. and Europe. Since the mission was officially approved in 2015, more than 4,000 people have contributed to Europa Clipper, including teams who work for contractors and subcontractors.
8. More than 2.6 million of us are riding along with the spacecraft, bringing greetings from one water world to another.
As part of a mission campaign called “Message in a Bottle,” the spacecraft is carrying a poem by U.S. Poet Laureate Ada Limón, cosigned by millions of people from nearly every country in the world. Their names have been stenciled onto a microchip attached to a tantalum metal plate that seals the spacecraft’s electronics vault. The plate also features waveforms of people saying the word “water” in over 100 spoken languages.
More About Europa Clipper
Europa Clipper’s three main science objectives are to determine the thickness of the moon’s icy shell and its interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission’s detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet.
Managed by Caltech in Pasadena, California, NASA’s Jet Propulsion Laboratory leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, for NASA’s Science Mission Directorate in Washington. The main spacecraft body was designed by APL in collaboration with JPL and NASA’s Goddard Space Flight Center in Greenbelt, Maryland, NASA’s Marshall Space Flight Center in Huntsville, Alabama, and NASA’s Langley Research Center in Hampton, Virginia. The Planetary Missions Program Office at Marshall executes program management of the Europa Clipper mission.
NASA’s Launch Services Program, based at Kennedy, manages the launch service for the Europa Clipper spacecraft, which will launch on a SpaceX Falcon Heavy rocket from Launch Complex 39A at Kennedy.

Sols 4304-4006: 12 Years, 42 Drill Holes, and Now… 1 Million ChemCam Shots!
In celebration of ChemCam’s milestone, here is a stunning image from its remote micro imager, showing details in the landscape far away. This image was taken by Chemistry & Camera (ChemCam) onboard NASA’s Mars rover Curiosity on Sol 4302 — Martian day 4,302 of the Mars Science Laboratory mission — on Sept. 12, 2024, at 09:20:51 UTC. NASA/JPL-Caltech Earth planning date: Friday, Sept. 13, 2024
Today, I need to talk about ChemCam, our laser and imaging instrument on the top of Curiosity’s mast. It one of the instruments in the “head” that gives Curiosity that cute look as if it were looking around tilting its head down to the rocks at the rover’s wheels. On Monday, 19th August the ChemCam team at CNES in France planned the 1 millionth shot and Curiosity executed it on the target Royce Lake on sol 4281 on Mars. Even as an Earth scientist used to really big numbers, this is a huge number that took me a while to fully comprehend. 1 000 000 shots! Congratulations, ChemCam, our champion for getting chemistry from a distance – and high-resolution images, too. If you are now curious how Curiosity’s ChemCam instrument works, here is the NASA fact sheet. And, of course, the team is celebrating, which is expressed by those two press releases, one from CNES in France and one from Los Alamos National Laboratory, the two institutions who collaborated to develop and build ChemCam and are now running the instrument for over 12 years! And the PI, Dr Nina Lanza from Los Alamos informs me that the first milestone – 10000 shots was reached as early as Sol 42, which was the sol the DAN instrument used its active mode for the first time. But before I am getting melancholic, let’s talk about today’s plan!
The drive ended fairly high up in the terrain, and that means we see a lot of the interesting features in the channel and generally around us. So, we are on a spot a human hiker would probably put the backpack down, take the water bottle out and sit down with a snack to enjoy the view from a nice high point in the landscape. Well, no such pleasures for Curiosity – and I am pretty sure sugar, which we humans love so much, wouldn’t be appreciated by rover gears anyway. So, let’s just take in the views! And that keeps Mastcam busy taking full advantage of our current vantage point. We have a terrain with lots of variety in front of us, blocks, boulders, flatter areas and the walls are layered, beautiful geology. Overall there are 11 Mastcam observations in the plan adding up to just about 100 individual frames, not counting those taken in the context of atmospheric observations, which are of course also in the plan. The biggest mosaics are on the targets “Western Deposit,” “Balloon Dome,” and “Coral Meadow.” Some smaller documentation images are on the targets “Wales Lake,” “Gnat Meadow,” and “Pig Chute.”
ChemCam didn’t have long to dwell on its milestone, as it’s busy again today. Of course, it will join Mastcam in taking advantage of our vantage point, taking three remote micro imager images on the landscape around us. LIBS chemistry investigations are targeting “Wales Lake,” “Gnat Meadow,” and “Pig Chute.” APXS is investigating two targets, “College Rock” and “Wales Lake,” which will also come with MAHLI documentation. With all those investigations together, we’ll be able to document the chemistry of many targets around us. There is such a rich variety of dark and light toned rocks, and with so much variety everywhere, it’s hard to choose and the team is excited about the three targeted sols … and planning over 4 hours of science over the weekend!
The next drive is planned to go to an area where there is a step in the landscape. Geologists love those steps as they give insights into the layers below the immediate surface. If you have read the word ‘outcrop’ here, then that’s what that means: access to below the surface. But there are also other interesting features in the area, hence we will certainly have an interesting workspace to look at! But getting there will not be easy as the terrain is very complex, so we cannot do it in just one drive. I think there is a rule of thumb here: the more excited the geo-team gets, the more skills our drivers need. Geologists just love rocks, but of course, no one likes driving offroad in a really rocky terrain – no roads on Mars. And right now, our excellent engineers have an extra complication to think about: they need to take extra care where and how to park so Curiosity can actually communicate with Earth. Why? Well, we are in a canyon, and those of you liking to hike, know what canyons mean for cell phone signals… yes, there isn’t much coverage, and that’s the same for Curiosity’s antenna. This new NASA video has more information and insights into the planning room, too! So, we’ll drive halfway to where we want to be but I am sure there will be interesting targets in the new workspace, the area is just so, so complex, fascinating and rich!
And that’s after Mars for you, after 12 years, 42 drill holes, and now 1 Million ChemCam shots. Go Curiosity go!!!

NASA, ESA/Matthias Maurer An astronaut aboard the International Space Station snapped this picture of the Moon as the station orbited 265 miles above the U.S. state of Minnesota on Dec. 17, 2021.
Astronauts aboard the orbital lab take images using handheld digital cameras, usually through windows in the station’s cupola, for Crew Earth Observations. Crew members have produced hundreds of thousands of images of the Moon and Earth’s land, oceans, and atmosphere.
On Saturday, Sept. 14, 2024, International Observe the Moon Night, everyone on Earth is invited to learn about lunar science, participate in celestial observations, and honor cultural and personal connection to the Moon. Find an event to join in the celebration.
