Sols 4295-4296: A Martian Moon and Planet Earth
Using an onboard focusing process, the Mars Hand Lens Imager (MAHLI) aboard NASA’s Mars rover Curiosity created this product by merging two to eight images previously taken by the MAHLI, which is located on the turret at the end of the rover’s robotic arm. Curiosity performed the merge on Sept. 4, 2024, at 06:30:48 UTC — sol 4294, or Martian day 4,294 of the Mars Science Laboratory mission. The onboard focus merge is sometimes performed on images acquired the same sol as the merge, and sometimes using pictures obtained earlier. Focus merging is a method to make a composite of images of the same target acquired at different focus positions to bring as many features as possible into focus in a single image. The MAHLI focus merge also serves as a means to reduce the number of images sent back to Earth. Each focus merge produces two images: a color, best-focus product and a black-and-white image that scientists can use to estimate focus position for each element of the best-focus product. So up to eight images can be merged, but the number of images returned to Earth is two. NASA/JPL-Caltech/MSSS Earth planning date: Wednesday, Sept. 4, 2024
Today’s two-sol plan contains the usual science blocks filled with contact science and remote science to observe and assess the geology surrounding us. However, the Mastcam team is hoping to capture a special celestial event above the Martian skyline as one of Mars’ moons, Phobos, will be in conjunction with Earth on the evening of the first sol of this plan. So everyone look up, and smile for the camera!
Coming back to our beautiful workspace, in this plan there is a focus on targeting the different colors and tones we can see in the bedrock with our suite of instruments. In the image above we can see some of these varying tones — including gray areas, lighter-toned areas, and areas of tan-colored bedrock — with an image from the MAHLI instrument, Curiosity’s onboard hand lens.
APXS is targeting “Campfire Lake,” a lighter-toned area, and “Gemini,” a more gray-toned area situated in front of the rover. MAHLI is taking a suite of close-up images of these targets too. ChemCam is then taking two LIBS measurements of “Crazy Lake” and “Foolish Lake,” both of which appear to have lighter tones. Mastcam is documenting this whole area with a workspace mosaic and an 8×2 mosaic of “Picture Puzzle,” named after the rock in the image above that was taken during the previous plan. Mastcam will also be capturing a 6×3 mosaic of an outcrop named “Outguard Spire” that has an interesting gray rim. Looking further afield, ChemCam has planned a long-distance RMI image of the yardang unit and Navcam is taking a suprahorizon movie and dust-devil survey for our continued observations of the atmosphere to round out this plan.

On the left, the Canopee transport carrier containing the European Service Module for NASA’s Artemis III mission arrives at Port Canaveral in Florida, on Tuesday, Sept. 3, 2024, before completing the last leg of its journey to the agency’s Kennedy Space Center’s Neil A. Armstrong Operations and Checkout via truck. On the right, NASA’s Pegasus barge, carrying several pieces of hardware for Artemis II, III, and IV arrives at NASA Kennedy’s Launch Complex 39 turn basin wharf on Thursday, Sept. 5, 2024. Credit: NASA From across the Atlantic Ocean and through the Gulf of Mexico, two ships converged, delivering key spacecraft and rocket components of NASA’s Artemis campaign to the agency’s Kennedy Space Center in Florida.
On Sept. 3, ESA (European Space Agency) marked a milestone in the Artemis III mission as its European-built service module for NASA’s Orion spacecraft completed a transatlantic journey from Bremen, Germany, to Port Canaveral, Florida, where technicians moved it to nearby NASA Kennedy. Transported aboard the Canopée cargo ship, the European Service Module—assembled by Airbus with components from 10 European countries and the U.S.—provides propulsion, thermal control, electrical power, and water and oxygen for its crews.
“Seeing multi-mission hardware arrive at the same time demonstrates the progress we are making on our Artemis missions,” said Amit Kshatriya, deputy associate administrator, Moon to Mars Program, at NASA Headquarters in Washington. “We are going to the Moon together with our industry and international partners and we are manufacturing, assembling, building, and integrating elements for Artemis flights.”
NASA’s Pegasus barge, the agency’s waterway workhorse for transporting large hardware by sea, ferried multi-mission hardware for the agency’s SLS (Space Launch System) rocket, the Artemis II launch vehicle stage adapter, the “boat-tail” of the core stage for Artemis III, the core stage engine section for Artemis IV, along with ground support equipment needed to move and assemble the large components. The barge pulled into NASA Kennedy’s Launch Complex 39B Turn Basin Thursday.
The spacecraft factory inside NASA Kennedy’s Neil Armstrong Operations and Checkout Building is set to buzz with additional activity in the coming months. With the Artemis II Orion crew and service modules stacked together and undergoing testing, and engineers outfitting the Artemis III and IV crew modules, engineers soon will connect the newly arrived European Service Module to the crew module adapter, which houses electronic equipment for communications, power, and control, and includes an umbilical connector that bridges the electrical, data, and fluid systems between the crew and service modules.
The SLS rocket’s cone-shaped launch vehicle stage adapter connects the core stage to the upper stage and protects the rocket’s flight computers, avionics, and electrical devices in the upper stage system during launch and ascent. The adapter will be taken to Kennedy’s Vehicle Assembly Building in preparation for Artemis II rocket stacking operations.
The boat-tail, which will be used during the assembly of the SLS core stage for Artemis III, is a fairing-like structure that protects the bottom end of the core stage and RS-25 engines. This hardware, picked up at NASA’s Michoud Assembly Facility in New Orleans, will join the Artemis III core stage engine section housed in the spaceport’s Space Systems Processing Facility.
The Artemis IV SLS core stage engine section arrived from NASA Michoud and also will transfer to the center’s processing facility ahead of final assembly.
Under the Artemis campaign, NASA will land the first woman, first person of color, and its first international partner astronaut on the lunar surface, establishing long-term exploration for scientific discovery and preparing for human missions to Mars. The agency’s SLS rocket and Orion spacecraft, and supporting ground systems, along with the human landing system, next-generation spacesuits and rovers, and Gateway, serve as NASA’s foundation for deep space exploration.

Technicians test a set of massive solar arrays measuring about 46.5 feet (14.2 meters) long and about 13.5 feet (4.1 meters) high for NASA’s Europa Clipper spacecraft inside the agency’s Payload Hazardous Servicing Facility at Kennedy Space Center in Florida on Aug. 7.Credits: NASA/Kim Shiflett NASA and SpaceX are targeting a launch period opening Thursday, Oct. 10, for the agency’s Europa Clipper mission, which will help scientists determine if one of Jupiter’s icy moons could support life. The mission will launch on a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.
Europa Clipper will carry nine instruments and a gravity science experiment aboard to gather detailed measurements as it orbits Jupiter and conducts multiple close flybys of its moon, Europa. Research suggests an ocean twice the volume of all of Earth’s oceans exists under Europa’s icy crust.
Media interested in covering the Europa Clipper launch must apply for media accreditation. Deadlines for accreditation are as follows:
U.S. citizens representing domestic or international media must apply for accreditation by 11:59 p.m. EDT, Friday, Sept. 27. International media without U.S. citizenship must apply by 11:59 p.m., Friday, Sept. 20. Media requiring special logistical arrangements, such as space for satellite trucks, tents, or electrical connections, should email ksc-media-accreditat@mail.nasa.gov by Tuesday, Oct. 1.
A copy of NASA’s media accreditation policy is available online. For questions about accreditation, please email: ksc-media-accreditat@mail.nasa.gov. For other mission questions, please contact NASA Kennedy’s newsroom at 321-867-2468.
Para obtener información sobre cobertura en español en el Centro Espacial Kennedy o si desea solicitar entrevistas en español, comuníquese con Antonia Jaramillo: 321-501-8425, o Messod Bendayan: 256-930-1371.
Accredited media will have the opportunity to participate in a series of prelaunch briefings and interviews with key mission personnel, including a briefing the week of Sept. 9. NASA will communicate additional details regarding the media event schedule as the launch date approaches.
NASA also will post updates on spacecraft launch preparations on NASA’s Europa Clipper blog.
Clipper’s primary science goal is to determine whether there are places below the surface of Europa that could support life. The mission’s three main science objectives are to understand the nature of the ice shell and the ocean beneath it, along with the moon’s composition and 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 in Southern California leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, for NASA Headquarters in Washington. The main spacecraft body was designed by APL in collaboration with JPL and NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The Planetary Missions Program Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama, 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.

Lunar geologist Zachary Morse scrabbles over Earth’s rocky landscapes to test equipment for future missions to the Moon and Mars.
Name: Zachary Morse
Title: Assistant Research Scientist in Planetary Geology
Organization: The Planetary Geology, Geophysics and Geochemistry Laboratory, Science Directorate (Code 698)
Zachary Morse is an assistant research scientist in planetary geology at NASA’s Goddard Space Flight Center in Greenbelt, Md. Photo courtesy of Zachary Morse What do you do and what is most interesting about your role here at Goddard? How do you help support Goddard’s mission?
I work with teams that integrate field instrumentation into future lunar and Mars exploration missions. We go to analog field sites, places on Earth that are geologically similar to the Moon or Mars, to test field instruments. I also support the development of science operations for crewed exploration of the lunar surface.
Why did you become a geologist? What is your educational background?
I always knew that I wanted to study space. In college I started in engineering, but switched to geology because much of the science NASA does on the Moon or Mars involves studying the rocks.
In 2013, I got a B.S. in geology from West Virginia University. In 2018, I got a Ph.D. in planetary science from Western University in London, Ontario.
“I work with teams that integrate field instrumentation into future lunar and Mars exploration missions,” said Zachary. “We go to analog field sites, places on Earth that are geologically similar to the Moon or Mars, to test field instruments.”Photo courtesy of Zachary Morse What brought you to Goddard?
In January 2020, I came to Goddard to do a post-doctoral fellowship because I wanted to work on the Remote, In Situ, and Synchrotron Studies for Science and Exploration 2 (Rise2) project. We go into the field to test handheld geologic instruments that could later be incorporated into missions.
What have been some of your favorite trips into the field?
Iceland, Hawaii, and the New Mexico desert, which is our primary field site for Rise2. These were organized as part of the Goddard Instrument Field Team, a group that hosts trips each year to different analog field sites.
The Iceland trip was my favorite because the place we got to explore looked almost exactly like pictures of the Moon’s surface. It was beautiful and the right setting to learn about the Earth and the Moon. Our team was about 40 people. We were there for two weeks. We mostly camped.
It was definitely a unique experience, one hard to put in words. On Earth, you would normally go camping in a lush forest. But there were no trees, just rock and dust. It was absolutely beautiful in its own way.
The Hawaii trip was also unique. Our team of about 30 people spent almost the entire 10 days in the lava tubes. Not many people get to go into lava tubes. It was very exciting. The biggest part of the lava tube was about 20 feet high and about 10 feet wide. The smallest was so small we had to crawl through.
How do you document field work?
In addition to scientific data, we always take pictures of the rocks and outcrops. It is important to document what a site is like before people interact with it. Sometimes we collect rock samples to bring back to the lab, but we leave the place as we found it.
“I always knew that I wanted to study space,” said Zachary. “In college I started in engineering, but switched to geology because much of the science NASA does on the Moon or Mars involves studying the rocks.”Photo courtesy of Zachary Morse Where do you see yourself in five years?
I hope to remain at Goddard; I love it. The team is great and the science is fascinating and important. I want to keep pursuing opportunities for field work. My main goal is to get involved in a lunar mission and support Artemis lunar exploration.
What do you do for fun?
I love the outdoors. I love kayaking on lakes, rivers, and streams. My favorite place is in the Adirondacks. I also love hiking, which I do all over, especially in West Virginia.
Who is your mentor and what did your mentor teach you?
Kelsey Young is my supervisor and mentor. She has taught me so many things including how missions will function and how we can best test equipment in the field for future missions. She taught me how to be organized and focused.
Kelsey Young Dives Into Fieldwork With Aplomb Who inspires you?
Jack Schmitt is an Apollo 17 astronaut who inspired me because he is a geologist. He was the first and only professional geologist who walked on the surface of the Moon during the Apollo missions. I have heard him speak many times and have personally met him.
I would jump at the chance to be the next geologist-astronaut!
What rock formations in the world would you like to explore?
Top of my list would be to explore Acadia National Park in Maine. There is a ton of diverse geology in a small area and the pictures all look stunning. I would also love to visit Glacier National Park to experience the glacier before it melts.

NASA, ESA Missions Help Scientists Uncover How Solar Wind Gets Energy
Since the 1960s, astronomers have wondered how the Sun’s supersonic “solar wind,” a stream of energetic particles that flows out into the solar system, continues to receive energy once it leaves the Sun. Now, thanks to a lucky lineup of a NASA and an ESA (European Space Agency)/NASA spacecraft both currently studying the Sun, they may have discovered the answer — knowledge that is a crucial piece of the puzzle to help scientists better forecast solar activity between the Sun and Earth.
A paper published in the Aug. 30, 2024, issue of the journal Science provides persuasive evidence that the fastest solar winds are powered by magnetic “switchbacks,” or large kinks in the magnetic field, near the Sun.
“Our study addresses a huge open question about how the solar wind is energized and helps us understand how the Sun affects its environment and, ultimately, the Earth,” said Yeimy Rivera, co-leader of the study and a postdoctoral fellow at the Smithsonian Astrophysical Observatory, part of Center for Astrophysics | Harvard & Smithsonian. “If this process happens in our local star, it’s highly likely that this powers winds from other stars across the Milky Way galaxy and beyond and could have implications for the habitability of exoplanets.”
This artist’s concept shows switchbacks, or large kinks in the Sun’s magnetic field. NASA’s Goddard Space Flight Center/Conceptual Image Lab/Adriana Manrique Gutierrez Previously, NASA’s Parker Solar Probe found that these switchbacks were common throughout the solar wind. Parker, which became the first craft to enter the Sun’s magnetic atmosphere in 2021, allowed scientists to determine that switchbacks become more distinct and more powerful close to the Sun. Up to now, however, scientists lacked experimental evidence that this interesting phenomenon actually deposits enough energy to be important in the solar wind.
“About three years ago, I was giving a talk about how fascinating these waves are,” said co-author Mike Stevens, astrophysicist at the Center for Astrophysics. “At the end, an astronomy professor stood up and said, ‘that’s neat, but do they actually matter?’”
To answer this, the team of scientists had to use two different spacecraft. Parker is built to fly through the Sun’s atmosphere, or “corona.” ESA’s and NASA’s Solar Orbiter mission is also on an orbit that takes it relatively close to the Sun, and it measures solar wind at larger distances.
The discovery was made possible because of a coincidental alignment in February 2022 that allowed both Parker Solar Probe and Solar Orbiter to measure the same solar wind stream within two days of each other. Solar Orbiter was almost halfway to the Sun while Parker was skirting the edge of the Sun’s magnetic atmosphere.

“We didn’t initially realize that Parker and Solar Orbiter were measuring the same thing at all. Parker saw this slower plasma near the Sun that was full of switchback waves, and then Solar Orbiter recorded a fast stream which had received heat and with very little wave activity,” said Samuel Badman, astrophysicist at the Center for Astrophysics and the other co-lead of the study. “When we connected the two, that was a real eureka moment.”
Scientists have long known that energy is moved throughout the Sun‘s corona and the solar wind, at least in part, through what are known as “Alfvén waves.” These waves transport energy through a plasma, the superheated state of matter that makes up the solar wind.
However, how much the Alfvén waves evolve and interact with the solar wind between the Sun and Earth couldn’t be measured — until these two missions were sent closer to the Sun than ever before, at the same time. Now, scientists can directly determine how much energy is stored in the magnetic and velocity fluctuations of these waves near the corona, and how much less energy is carried by the waves farther from the Sun.
The new research shows that the Alfvén waves in the form of switchbacks provide enough energy to account for the heating and acceleration documented in the faster stream of the solar wind as it flows away from the Sun.
“It took over half a century to confirm that Alfvenic wave acceleration and heating are important processes, and they happen in approximately the way we think they do,” said John Belcher, emeritus professor from the Massachusetts Institute of Technology who co-discovered Alfvén waves in the solar wind but was not involved in this study.
In addition to helping scientists better forecast solar activity and space weather, such information helps us understand mysteries of the universe elsewhere and how Sun-like stars and stellar winds operate everywhere.
“This discovery is one of the key puzzle pieces to answer the 50-year-old question of how the solar wind is accelerated and heated in the innermost portions of the heliosphere, bringing us closer to closure to one of the main science objectives of the Parker Solar Probe mission,” said Adam Szabo, Parker Solar Probe mission science lead at NASA.
