5 Min Read 9 Phenomena NASA Astronauts Will Encounter at Moon’s South Pole
An artist’s rendering of an Artemis astronaut working on the Moon’s surface. Credits:
NASA NASA’s Artemis campaign will send the first woman and the first person of color to the Moon’s south polar region, marking humanity’s first return to the lunar surface in more than 50 years.
Here are some out-of-this-world phenomena Artemis astronauts will experience:
1. A Hovering Sun and Giant Shadows
This visualization shows the motions of Earth and the Sun as viewed from the South Pole of the Moon.
NASA’s Goddard Space Flight Center Near the Moon’s South Pole, astronauts will see dramatic shadows that are 25 to 50 times longer than the objects casting them. Why? Because the Sun strikes the surface there at a low angle, hanging just a few degrees above the horizon. As a result, astronauts won’t see the Sun rise and set. Instead, they’ll watch it hover near the horizon as it moves horizontally across the sky.
2. Sticky, Razor-Sharp Dust …
This dust particle came from a lunar regolith sample brought to Earth in 1969 by Apollo 11 astronauts. The particle is about 25 microns across, less than the width of an average human hair. The image was taken with a scanning electron microscope. The lunar dust, called regolith, that coats the Moon’s surface looks fine and soft like baking powder. But looks can be deceiving. Lunar regolith is formed when meteoroids hit the Moon’s surface, melting and shattering rocks into tiny, sharp pieces. The Moon doesn’t have moving water or wind to smooth out the regolith grains, so they stay sharp and scratchy, posing a risk to astronauts and their equipment.
3. … That’s Charged with Static Electricity
Astronaut Eugene Cernan, commander of Apollo 17, inside the lunar module on the Moon after his second moonwalk of the mission in 1972. His spacesuit and face are covered in lunar dust. Because the Moon has no atmosphere to speak of, its surface is exposed to plasma and radiation from the Sun. As a result, static electricity builds up on the surface, as it does when you shuffle your feet against a carpeted floor. When you then touch something, you transfer that charge via a small shock. On the Moon, this transfer can short-circuit electronics. Moon dust also can make its way into astronaut living quarters, as the static electricity causes it to easily stick to spacesuits. NASA has developed methods to keep the dust at bay using resistant textiles, filters, and a shield that employs an electric field to remove dust from surfaces.
4. A New Sense of Lightness
In 1972, Apollo 16 astronaut Charles Duke hammered a core tube into the Moon’s surface until it met a rock and wouldn’t go any farther. Then the hammer flew from his hand. He made four attempts to pick it up by bending down and leaning to reach for it. He gave up and returned to the rover to get tongs to finally pick up the hammer successfully.
NASA’s Johnson Space Center Artemis moonwalkers will have a bounce to their step as they traverse the lunar surface. This is because gravity won’t pull them down as forcefully as it does on Earth. The Moon is only a quarter of Earth’s size, with six times less gravity. Simple activities, like swinging a rock hammer to chip off samples, will feel different. While a hammer will feel lighter to hold, its inertia won’t change, leading to a strange sensation for astronauts. Lower gravity has perks, too. Astronauts won’t be weighed down by their hefty spacesuits as much as they would be on Earth. Plus, bouncing on the Moon is just plain fun.
5. A Waxing Crescent … Earth?
This animated image features a person holding a stick with a sphere on top that represents the Moon. The person is demonstrating an activity that helps people learn about the phases of the Moon by acting them out. NASA’s Jet Propulsion Laboratory When Artemis astronauts look at the sky from the Moon, they’ll see their home planet shining back at them. Just like Earthlings see different phases of the Moon throughout a month, astronauts will see an ever-shifting Earth. Earth phases occur opposite to Moon phases: When Earth experiences a new Moon, a full Earth is visible from the Moon.
6. An Itty-Bitty Horizon
A view from the Apollo 11 spacecraft in July 1969 shows Earth rising above the Moon’s horizon. NASA Because the Moon is smaller than Earth, its horizon will look shorter and closer. To someone standing on a level Earth surface, the horizon is 3 miles away, but to astronauts on the Moon, it’ll be only 1.5 miles away, making their surroundings seem confined.
7. Out-of-This-World Temperatures
This graphic shows maximum summer and winter temperatures near the lunar South Pole. Purple, blue, and green identify cold regions, while yellow to red signify warmer ones. The graphic incorporates 10 years of data from NASA’s LRO (Lunar Reconnaissance Orbiter), which has been orbiting the Moon since 2009.
NASA/LRO Diviner Seasonal Polar Data Because sunlight at the Moon’s South Pole skims the surface horizontally, it brushes crater rims, but doesn’t always reach their floors. Some deep craters haven’t seen the light of day for billions of years, so temperatures there can dip to minus 334 F. That’s nearly three times colder than the lowest temperature recorded in Antarctica. At the other extreme, areas in direct sunlight, such as crater rims, can reach temperatures of 130 F.
8. An Inky-Black Sky

NASA’s Scientific Visualization Studio The Moon, unlike Earth, doesn’t have a thick atmosphere to scatter blue light, so the daytime sky is black. Astronauts will see a stark contrast between the dark sky and the bright ground.
9. A Rugged Terrain

This visual was created using a digital elevation map from NASA LRO’s laser altimeter, LOLA. NASA’s Scientific Visualization Studio Artemis moonwalkers will find a rugged landscape that takes skill to traverse. The Moon has mountains, valleys, and canyons, but its most notable feature for astronauts on the surface may be its millions of craters. Near the South Pole, gaping craters and long shadows will make it difficult for astronauts to navigate. But, with training and special gear, astronauts will be prepared to meet the challenge.

For some people, working for NASA is a lifelong dream. For others, it is an interesting and perhaps unexpected opportunity that comes up at just the right time and place.
Everything from family ties and influential teachers to witnessing human spaceflight history and enjoying sci-fi entertainment has helped bring people of all backgrounds together at NASA’s Johnson Space Center in Houston. Several of them recently shared their inspiration to join the NASA team.
***
“As a kid, I always had my head up looking at the stars. I loved astronomy and seeing videos of humans walking on the Moon fascinated me! I wanted to be the first female to walk on the Moon. When Star Wars came out, I wanted to build my own R2-D2 that could explore the galaxies. I was curious how things worked (so I could build a robot) and a cousin told me about engineering. That was the name for what I wanted to do! So, I went to the High School for Engineering Professions in Houston. The guidance counselor there told me about an opportunity to apply for a summer internship with NASA as a junior. I got in and I’ve worked with NASA as much as I could since I was 16 years old – internships and full-time positions. I may not get the chance to be an astronaut and walk on the Moon, but I know I will play a role in helping achieve that dream for another female and a person of color!”
– Alicia Baker, engineering project manager for Portable Life Support System test support, JSC Engineering, Technology, and Science (JETS) Contract

I went to take your kid to work day and got to stand in front of a booster engine. I’ve wanted to work in the space industry ever since. I almost didn’t enter the field after getting my aerospace degree, but I was fortunate to take an Intro to Human Spaceflight class during my last quarter of college. Without that class and the professor (who had worked at Johnson) I wouldn’t be here today. I’m so glad my path led me here. Johnson is such a great place to be, and I can look back and tell little Margaret that we did it!”

NASA/Josh Valcarcel “I didn’t think I would ever work for NASA. But multiple professors in college encouraged me to challenge myself and do some space research. I realized that it was something that I was very passionate about. Thanks to my research work for the Europa Clipper as an undergraduate student, I got my first internship at NASA and subsequently an offer to join the Pathways Program. Now I am part of a small group of engineers that solve entry, descent, and landing problems for multiple missions on Earth, the Moon, and Mars.”

“Dad would take me to the viewing room of the original Mission Operations Control Room (MOCR) during the Apollo era. He was one of the people supporting MOCR in the Staff Support Room. I have worked at Johnson for 27 years [as a contractor] for Lockheed Martin, Hamilton Sundstrand, and Jacobs Technology.”
– David Fanelli, software engineer, Energy Systems Test Area
“In early 1969, when I was a boy, my uncle visited the Johnson Space Center and brought back astronaut and mission photos of the recently completed Apollo 8 lunar orbiting mission. Those photos, coupled with a Saturn V rocket model I assembled, and the Time Life records and books about the Apollo space program my parents purchased for me, sparked my imagination. I knew I wanted to work for NASA one day. It wasn’t until many years later that that dream became a reality, when I joined NASA’s co-op program for college students during my second attempt to become an aeronautical engineer. After I graduated college, I began working full time as a civil servant engineer at Johnson.”

“I remember watching Star Trek and Star Wars as a kid with my dad. I found some of his college notes in a box one day and thought the small, neat print on graph paper pads was really pretty. He went to the University of Texas at Austin to study astrophysics and engineering, but he never got to finish. Fast forward to 2022 and I find myself in Houston for an unknown amount of time, so I decided to go out and make some friends. I met a woman at a Geeky Game Night, and I learned that she was a food scientist at NASA! After talking some more, she told me to send her my resume. Later that week I received a call to set up an interview. I’m still in awe of how that one chance connection led me to my childhood dream of working at NASA.”
– Kristin Dillon, document/IT specialist, Space Food Systems Laboratory
“I grew up in a small agricultural village in India. My first introduction to spaceflight was reading Russian cosmonauts’ translated accounts of the Apollo-Soyuz Test Project as a young girl. I am still not sure whether my father picked that book for me on a whim or with a grand dream for his daughter, but it certainly had me hooked. However, I found my true calling to make human spaceflight safer and more efficient after witnessing the Columbia mishap. India, at the time, did not have a human spaceflight program. Thus started a 20-year-long grand adventure of seeking opportunities, pursuing them, immigrating to the United States, and finding my path to NASA, which culminated in a Pathways internship at Johnson.”

On Sept. 9, 1994, space shuttle Discovery took to the skies on its 19th trip into space. During their 11-day mission, the STS-64 crew of Commander Richard “Dick” N. Richards, Pilot L. Blaine Hammond, and Mission Specialists Jerry M. Linenger, Susan J. Helms, Carl J. Meade, and Mark C. Lee demonstrated many of the space shuttle’s capabilities. They used a laser instrument to observe the Earth’s atmosphere, deployed and retrieved a science satellite, and used the shuttle’s robotic arm for a variety of tasks, including studying the orbiter itself. During a spacewalk, Lee and Meade tested a new device to rescue astronauts who found themselves detached from the vehicle. Astronauts today use the device routinely for spacewalks from the International Space Station.

In November 1993, NASA announced the five-person all-veteran STS-64 crew. Richards, selected as an astronaut in 1980, had made three previous spaceflights, STS-28, STS-41, and STS-50. Lee, a member of the astronaut class of 1984, had two flights to his credit, STS-30 and STS-47, as did Meade, selected in 1985 and a veteran of STS-38 and STS-50. Each making their second trip into space, Hammond, selected in 1984 had flown on STS-39, and Helms, from the class of 1990 had flown on STS-54. In February 1994, NASA added first time space flyer Linenger to the crew, partly to make him eligible for a flight to Mir. He holds the distinction as the first member of his astronaut class of 1992 to fly in space.

Middle: Space shuttle Discovery arrives at Launch Pad 39B, left, with space shuttle Endeavour still on Launch Pad 39A. Right: The STS-64 crew exits crew quarters at KSC on their way to the launch.
Discovery returned to NASA’s Kennedy Space Center (KSC) in Florida following its previous flight, the STS-60 mission, in February 1994. Workers in KSC’s Orbiter Processing Facility (OPF) removed the previous payload and began to service the orbiter. On May 26, workers moved Discovery into the Vehicle Assembly Building for temporary storage to make room in the OPF for Atlantis, just returned from Palmdale, California, where it underwent modifications to enable extended duration flights and dockings with space stations. Discovery returned to the OPF for payload installation in July, and rolled back to the VAB on Aug. 11 for mating with its external tank and solid rocket boosters. Discovery rolled out to Launch Pad 39B on Aug. 19, with its sister ship Endeavour still on Launch Pad 39A following the previous day’s launch abort. The six-person crew traveled to KSC to participate in the Terminal Countdown Demonstration Test, essentially a dress rehearsal for the launch countdown, on Aug. 24.
Liftoff of Discovery on the STS-64 mission.
On Sept. 9, 1994, after a more than two-hour delay caused by inclement weather, Discovery thundered into the sky to begin the STS-64 mission. Eight and a half minutes later, the orbiter and its crew reached space, and with a firing of the shuttle’s Orbiter Maneuvering System (OMS) engines they entered a 160-mile orbit inclined 57 degrees to the equator, ideal for Earth and atmospheric observations. The crew opened the payload bay doors, deploying the shuttle’s radiators, and removed their bulky launch and entry suits, stowing them for the remainder of the flight. They began to convert their vehicle into a science platform.

One of the primary payloads on STS-64, the LIDAR (light detection and ranging) In-space Technology Experiment (LITE), mounted in Discovery’s forward payload bay, made the first use of a laser to study Earth’s atmosphere, cloud cover, and airborne dust from space. Lee, with help from Richards and Meade, activated LITE, built at NASA’s Langley Research Center in Hampton, Virginia, on the flight’s first day. The experiment operated for 53 hours during the mission, gathering 43 hours of high-rate data shared with 65 groups in 20 countries.

The Shuttle Plume Impingement Flight Experiment (SPIFEX), built at NASA’s Johnson Space Center (JSC) in Houston, consisted of a package of instruments positioned on the end of a 33-foot boom, to characterize the behavior of the shuttle’s Reaction Control System (RCS) thrusters. On the flight’s second day, Helms used the shuttle’s Remote Manipulator System (RMS), or robotic arm, to pick up SPIFEX. Over the course of the mission, she, Lee, and Hammond took turns operating the arm to obtain 100 test points during various thruster firings. A video camera on SPIFEX returned images of Discovery from several unusual angles.

Middle: Discovery approaches SPARTAN during the rendezvous. Right: Astronaut Susan J. Helms operating the Shuttle’s Remote Manipulator System prepares to grapple SPARTAN.
On the mission’s fifth day, Helms used the RMS to lift the Shuttle Pointed Autonomous Research Tool for Astronomy-201 (SPARTAN-201) satellite out of the payload bay and released it. Two and a half minutes later, SPARTAN activated itself, and Richards maneuvered Discovery away from the satellite so it could begin its science mission. On flight day seven, Discovery began its rendezvous with SPARTAN, and Hammond flew the shuttle close enough for Helms to grapple it with the arm and place it back in the payload bay. During its two-day free flight, SPARTAN’s two telescopes studied the acceleration and velocity of the solar wind and measured aspects of the Sun’s corona or outer atmosphere.

On flight day seven, in preparation for the following day’s spacewalk, the astronauts lowered the pressure in the shuttle from 14.7 pounds per square inch (psi) to 10.2 psi to reduce the likelihood of the spacewalkers, Lee and Meade, from developing decompression sickness, also known as the bends. As an added measure, the two spent 15 minutes breathing pure oxygen before donning their spacesuits and exiting the shuttle’s airlock.

Meade tests the SAFER during an untethered spacewalk. Right: Meade, left, tests the ability of the SAFER to stop his spinning as Lee looks on.
The main tasks of the spacewalk involved testing the Simplified Aid for EVA (Extravehicular Activity) Rescue (SAFER), a device designed at JSC that attaches to the spacesuit’s Portable Life Support System backpack. The SAFER contains nitrogen jets that an astronaut can use, should he or she become untethered, to fly back to the vehicle, either the space shuttle or the space station. The two put the SAFER through a series of tests, including a familiarization, a system engineering evaluation, a crew rescue evaluation, and a precision flight evaluation. During the tests, Lee and Meade remained untethered from the shuttle, the first untethered spacewalk since STS-51A in November 1984. Lee and Meade successfully completed all the tests and gave the SAFER high marks. Astronauts conducting spacewalks from the space station use the SAFER as a standard safety device. Following the 6-hour 51-minute spacewalk, the astronauts raised the shuttle’s atmosphere back to 14.7 psi.

Mission managers had extended the original flight duration by one day for additional data collection for the various payloads. On the planned reentry day, Sept. 19, bad weather at KSC forced the crew to spend an additional day in space. The next day, continuing inclement weather caused them to wave off the first two landing attempts at KSC and diverted to Edwards Air Force Base (AFB) in California.
Left: Richard Richards brings Discovery home at California’s Edwards Air Force Base. Middle: Workers at Edwards safe Discovery after its return from STS-64. Right: Discovery takes off from Edwards atop a Shuttle Carrier Aircraft for the ferry flight to NASA’s Kennedy Space Center in Florida.
On Sept. 20, they closed Discovery’s payload bay doors, donned their launch and entry suits, and strapped themselves into their seats for entry and landing. They fired Discover’s OMS engines to drop them out of orbit. Richards piloted Discovery to a smooth landing at Edwards, ending the 10-day 22-hour 50-minute flight. The crew had orbited the Earth 176 times. Workers at Edwards safed the vehicle and placed it atop a Shuttle Carrier Aircraft for the ferry flight back to KSC. The duo left Edwards on Sept. 26, and after an overnight stop at Kelly AFB in San Antonio, arrived at KSC the next day. Workers there began preparing Discovery for its next flight, the STS-63 Mir rendezvous mission, in February 1995.

The four-person crew of the Polaris Dawn mission pictured wearing their SpaceX extravehicular activity suits.Credit: SpaceX NASA researchers will soon benefit from a suite of experiments flying aboard a new fully-commercial human spaceflight mission, strengthening future agency science as we venture to the Moon, Mars and beyond.
The experiments are flying as part of the Polaris Dawn mission which launched aboard a SpaceX Dragon spacecraft and Falcon 9 rocket earlier today.
The four-person Polaris Dawn crew of Jared Isaacman, Scott “Kidd” Poteet, Sarah Gillis, and Anna Menon will conduct science during the mission including essential health and human performance research for NASA’s Human Research Program. The research will help NASA scientists better understand how exposure to space conditions affects the human body. The crew will test new medical approaches and technology on telemedicine capabilities, gather data on space motion sickness, and better characterize flight-associated injury risks.
“Each mission, whether the crew is comprised of commercial or NASA astronauts, provides a key opportunity to expand our knowledge about how spaceflight affects human health,” said Jancy McPhee, associate chief scientist for human research at NASA. “Information gathered from Polaris Dawn will give us critical insights to help NASA plan for deeper space travel to the Moon and Mars.”
The crew will test drive, a commercial device that can collect and integrate measurements of health, including blood pressure, heart rate, respiration rate, and temperature. The technology also provides ultrasound imaging and larynx and throat-focused video camera capabilities, and includes an experimental telemedicine feature that could help diagnose crew members in near-real time.
To test this technology during the mission, crew members will compare vital sign collection from the device with data gathered from standard periodic health status exams. The technology’s telemedicine feature, which relies on SpaceX’s Starlink communications system to connect with doctors and specialists on Earth, will also be tested during a simulation. During the test, the device will attempt to offer an appropriate diagnosis based on crew inputs and available documentation.
“Crew members will need to be more self-reliant during lengthy missions, and we hope that telemedicine can provide crews with assistance,” said McPhee.
Another research project aims to better understand and prevent the motion sickness symptoms that many astronauts experience in space. Participating crew members will describe their motion sickness symptoms, what interventions they tried to alleviate their symptoms, and whether any approaches helped.
A separate NASA-based research project will survey crew members after their mission to see whether they experienced any injuries or discomfort during re-entry to Earth.
“Our team will take the crew’s survey data and combine it with information gathered from sensors on the spacecraft. This will allow us to link crews’ reported experiences and health outcomes with the spacecraft’s dynamics and landing loads,” said Preston Greenhalgh, an injury biomechanist at NASA who is leading this work.
Crew members also will participate in a variety of other health studies on behalf of the NASA-funded TRISH (Translational Research Institute for Health), a consortium with various academic institutions. As part of that work, the Polaris Dawn mission will set a new baseline for collecting standard health data on commercial spaceflights, creating a complement to the datasets routinely collected from NASA astronauts and missions.
Polaris Dawn crew members participating in these TRISH studies will provide data about how spaceflight affects mental and physical health through a rigorous set of medical tests and scans completed before, after, and during the mission. The work will include assessments of behavior, sleep, bone density, eye health, cognitive function, and other factors, as well as analysis of blood, urine, and respiration.
“We’re so grateful to the crew members who volunteer to be part of NASA’s work. The insights that we gain from each study may trigger breakthroughs that will help ensure future mission success,” said McPhee.
____
NASA’s Human Research Program pursues the best methods and technologies to support safe, productive human space travel. Through science conducted in laboratories, ground-based analogs, commercial missions, and the International Space Station, the program scrutinizes how spaceflight affects human bodies and behaviors. Such research continues to drive NASA’s mission to innovate ways that keep astronauts healthy and mission-ready as space exploration expands to the Moon, Mars, and beyond.
