After the launch, Intuitive Machines’ lunar lander, Athena, will spend approximately one week in transit to the Moon before landing on the lunar surface no earlier than Thursday, March 6. The lander will carry NASA science investigations and technology demonstrations to further our understanding of the Moon’s environment and help prepare for future human missions to the lunar surface, as part of the agency’s Moon to Mars exploration approach.
Among the items on Intuitive Machines’ lander, the IM-2 mission will be one of the first on-site demonstrations of resource use on the Moon. A drill and mass spectrometer will measure the potential presence of volatiles or gases from lunar soil in Mons Mouton, a lunar plateau in the Moon’s South Pole. In addition, a passive Laser Retroreflector Array (LRA) on the top deck of the lander will bounce laser light back at any orbiting or incoming spacecraft to give future spacecraft a permanent reference point on the lunar surface. Other technology instruments on this delivery will demonstrate a robust surface communications system and deploy a propulsive drone that can hop across the lunar surface.
Launching as a rideshare with the IM-2 delivery, NASA’s Lunar Trailblazer spacecraft also will begin its journey to lunar orbit, where it will map the distribution of the different forms of water on the Moon.

Before Apollo astronauts set foot upon the Moon, much remained unknown about the lunar surface. While most scientists believed the Moon had a solid surface that would support astronauts and their landing craft, a few believed a deep layer of dust covered it that would swallow any visitors. Until 1964, no closeup photographs of the lunar surface existed, only those obtained by Earth-based telescopes.
NASA’s Jet Propulsion Laboratory in Pasadena, California, managed the Ranger program, a series of spacecraft designed to return closeup images before impacting on the Moon’s surface. Ranger 7 first accomplished that goal in July 1964. On Feb. 17, 1965, its successor Ranger 8 launched toward the Moon, and three days later returned images of the Moon. The mission’s success helped the country meet President John F. Kennedy’s goal of a human Moon landing before the end of the decade.

Ranger 8 lifted off from Cape Kennedy, now Cape Canaveral, Florida, on Feb. 17, 1965. The Atlas-Agena rocket first placed the spacecraft into Earth orbit before sending it on a lunar trajectory. The next day, the spacecraft carried out a mid-course correction, and on Feb. 20, Ranger 8 reached the Moon. The spacecraft’s six cameras turned on as planned, about eight minutes earlier than its predecessor to obtain images comparable in resolution to ground-based photographs for calibration purposes. Ranger 8 took its first photograph at an altitude of 1,560 miles, and during its final 23 minutes of flight, the spacecraft sent back 7,137 images of the lunar surface. The last image, taken at an altitude of 1,600 feet and 0.28 seconds before Ranger 8 impacted at 1.67 miles per second, had a resolution of about five feet. The spacecraft impacted 16 miles from its intended target in the Sea of Tranquility, ending a flight of 248,900 miles. Scientists had an interest in this area of the Moon as a possible landing zone for a future human landing, and indeed Apollo 11 landed 44 miles southeast of the Ranger 8 impact site in July 1969.

Television networks broadcast Ranger 9’s images of the Alphonsus crater and the surrounding area “live” as the spacecraft approached its impact site in the crater – letting millions of Americans see the Moon up-close as it happened. Based on the photographs returned by the last three Rangers, scientists felt confident to move on to the next phase of robotic lunar exploration, the Surveyor series of soft landers. The Ranger photographs provided confidence that the lunar surface could support a soft-landing and that the Sea of Tranquility presented a good site for the first human landing. A little more than four years after the final Ranger images, Apollo 11 landed the first humans on the Moon.

The impacts of the Ranger probes left visible craters on the lunar surface, later photographed by orbiting spacecraft. Lunar Orbiter 2 and Apollo 16 both imaged the Ranger 8 impact site at relatively low resolution in 1966 and 1972, respectively. The Lunar Reconnaissance Orbiter imaged the crash site in greater detail in 2012.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Astronaut Jeanette Epps extracts DNA samples from bacteria colonies for genomic analysis aboard the International Space Station’s Harmony module.NASA In an effort to learn more about astronaut health and the effects of space on the human body, NASA is conducting a new experiment aboard the International Space Station to speed up the detection of antibiotic-resistant bacteria, thus improving the health safety not only of astronauts but patients back on Earth.
Infections caused by antibiotic-resistant bacteria can be difficult or impossible to treat, making antibiotic resistance a leading cause of death worldwide and a global health concern.
Future astronauts visiting the Moon or Mars will need to rely on a pre-determined supply of antibiotics in case of illness. Ensuring those antibiotics remain effective is an important safety measure for future missions.
The Genomic Enumeration of Antibiotic Resistance in Space (GEARS) experiment, which is managed by NASA’s Ames Research Center in California’s Silicon Valley, involves astronauts swabbing interior surfaces across the space station and testing those samples for evidence of antibiotic-resistant bacteria, and in particular Enterococcus faecalis, a type of bacteria commonly found in the human body. The experiment is the first step in a series of work that seeks to better understand how organisms grow in a space environment, and how those similarities and differences might help improve research back on Earth.
“Enterococcus is a type of organism that’s been with us since our ancestors crawled out of the ocean, and is a core member of the human gut,” said Christopher Carr, assistant professor at the Georgia Institute of Technology and co-principal investigator of GEARS. “It’s able to survive inside and outside of its host, which has allowed it to become the second highest leading cause of hospital-acquired infections. We want to understand how this type of organism is adapting to the space environment.”
The GEARS experiment seeks to improve the detection and identification of these bacteria, building on existing efforts to understand what organisms grow on the station’s surfaces.
“We’ve been monitoring the surfaces of the space station since 2000, but this experiment will give us insight beyond the identities of present organisms, which is currently all that is used for risk assessment,” said Sarah Wallace, a microbiologist at NASA’s Johnson Space Center in Houston and co-principal investigator of GEARS. “With the station orbiting close to Earth, it’s a low-risk space to evaluate and learn more about the frequency of this bacteria and how it responds to the space environment so we can apply this understanding to missions to the Moon and Mars, where resupplies are more complex.”
Over the next year, astronauts will swab parts of the station and analyze samples by adding an antibiotic to the medium in which the samples will grow. The results will reveal where this and other resistant bacteria are growing and whether they can persist or spread across the station.
I hope we can shine a light on rapidly analyzing bacteria: if we can do this in space, we can do it on Earth, too.
Sarah WAllace
NASA Microbiologist
The experiment was originally launched to the ISS on the 30th SpaceX commercial resupply services (CRS) mission in March 2024, and the first round of GEARS testing turned up surprising results: very few resistant bacteria colonies, none of which were E. faecalis. This bodes well for the threat of antibiotic resistance in space.
“There was some cleaning done before swabbing the station, which may have removed some bacteria,” said Carr. To better understand how and where risky bacteria may live, the astronauts paused some cleaning before the second round of swabbing.
“We want the astronauts to have a clean environment, but we also want to test those high-touch areas, so they intentionally and briefly avoided cleaning some areas so we can understand how bacteria may grow or spread on the station.”
This experiment is the first study to perform metagenomic sequencing in space, a method that analyzes all the genetic material in a sample to identify and characterize all organisms that are present, an important research and medical diagnostic capability for future deep space missions.
The GEARS team hopes to create a rapid workflow to analyze bacteria samples, reducing the time between swabbing and test results from days to hours. That workflow could be applied in hospitals and make a huge impact when treating hospital-acquired infections from antibiotic-resistant microbes.
The result could save lives – more than 35,000 people die each year as a result of antibiotic-resistant infections. The issue is personal to Wallace, who lost a family member to a hospital-acquired infection.
“It’s not that uncommon: so many people have experienced this kind of loss,” said Wallace. “A method to give an answer in a matter of hours is huge and profound. It’s my job to keep the crew healthy, but we’re also passionate about bringing that work back down to Earth. I hope we can shine a light on rapidly analyzing bacteria: if we can do this in space, we can do it on Earth, too.”
Genomic Enumeration of Antibiotic Resistance in Space (GEARS) was funded by the Biological and Physical Sciences Space Biology Program, with pioneering funding and support from the Mars Campaign office.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
During the Apollo program, when NASA sent humans to the Moon, those missions took several days to reach the Moon. The fastest of these was Apollo 8, which took just under three days to go from Earth orbit to orbit around the Moon.
Now it’s possible to save some fuel by flying different kinds of trajectories to the Moon that are shaped in such a way to save fuel. And those trajectories can take more time, potentially weeks or months, to reach the Moon, depending on how you do it.
Mars is further away, about 50 percent further away from the Sun than Earth is. And reaching Mars generally takes somewhere between seven to ten months, flying a relatively direct route.
NASA’s Mars Reconnaissance Orbiter mission took about seven and a half months to reach Mars. And NASA’s MAVEN mission took about ten months to reach Mars.
Jupiter is about five times further away from the Sun than the Earth is. And so in order to make those missions practical, we have to find ways to reduce the fuel requirements. And the way we do that is by having the spacecraft do some flybys of Earth and or Venus to help shape the spacecraft’s trajectory and change the spacecraft’s speed without using fuel. And using that sort of approach, it takes between about five to six years to reach Jupiter.
So NASA’s Galileo mission, the first mission to Jupiter, took just a little over six years. And then NASA’s second mission to Jupiter, which was called Juno, took just under five years.
So to get to the Moon takes several days. To get to Mars takes seven to ten months. And getting to Jupiter takes between five and six years.
