NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute/Alex Parker This image, taken by NASA’s New Horizons spacecraft on July 14, 2015, is the most accurate natural color image of Pluto. This natural-color image results from refined calibration of data gathered by New Horizons’ color Multispectral Visible Imaging Camera (MVIC). The processing creates images that would approximate the colors that the human eye would perceive, bringing them closer to “true color” than the images released near the encounter. This single color MVIC scan includes no data from other New Horizons imagers or instruments added. The striking features on Pluto are clearly visible, including the bright expanse of Pluto’s icy, nitrogen-and-methane rich “heart,” Sputnik Planitia.

NASA’s coverage ends approximately 30 minutes after undocking when space station joint operations with Axiom Space and SpaceX conclude. Axiom Space will resume coverage of Dragon’s re-entry and splashdown on the company’s website.
A collaboration between NASA and ISRO allowed Axiom Mission 4 to deliver on a commitment highlighted by President Trump and Indian Prime Minister Narendra Modi to send the first ISRO astronaut to the station. The space agencies participated in five joint science investigations and two in-orbit science, technology, engineering, and mathematics demonstrations. NASA and ISRO have a long-standing relationship built on a shared vision to advance scientific knowledge and expand space collaboration.
The private mission also carried the first astronauts from Poland and Hungary to stay aboard the space station.
The International Space Station is a springboard for developing a low Earth orbit economy. NASA’s goal is to achieve a strong economy off the Earth where the agency can purchase services as one of many customers to meet its science and research objectives in microgravity. NASA’s commercial strategy for low Earth orbit provides the government with reliable and safe services at a lower cost, enabling the agency to focus on Artemis missions to the Moon in preparation for Mars while also continuing to use low Earth orbit as a training and proving ground for those deep space missions.

The crew of NASA’s SpaceX Crew-11 mission sit inside a Dragon training spacecraft at SpaceX in Hawthorne, California. Pictured from left: Roscosmos cosmonaut Oleg Platonov, NASA astronauts Mike Fincke and Zena Cardman, and JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui (Credit: SpaceX). NASA’s SpaceX Crew-11 mission is set to launch a four-person crew to the International Space Station later this summer. Some of the crew have volunteered to participate in a series of experiments to address health challenges astronauts may face on deep space missions during NASA’s Artemis campaign and future human expeditions to Mars.
The research during Crew-11 includes simulated lunar landings, tactics to safeguard vision, and other human physiology studies led by NASA’s Human Research Program.
Select crew members will participate in a series of simulated Moon landings, before, during, and after their flight. Using a handheld controller and multiple screens, the astronauts will fly through simulated scenarios created to resemble the lunar South Pole region that Artemis crews plan to visit. This experiment allows researchers to evaluate how different gravitational forces may disorient astronauts and affect their ability to pilot a spacecraft, like a lunar lander.
“Even though many landing tasks are automated, astronauts must still know how to monitor the controls and know when to take over to ensure a safe landing,” said Scott Wood, a neuroscientist at NASA’s Johnson Space Center in Houston coordinating the scientific investigation. “Our study assesses exactly how changes in gravity affect spatial awareness and piloting skills that are important for navigating these scenarios.”
A ground control group completing the same tasks over a similar timeframe will help scientists better understand gravitational effects on human performance. The experiment’s results could inform the pilot training needed for future Artemis crews.
“Experiencing weightlessness for months and then feeling greater levels of gravity on a planet like Mars, for example, may increase the risk of disorientation,” said Wood. “Our goal is to help astronauts adapt to any gravitational change, whether it’s to the Moon, a new planet, or landing back on Earth.”
Other studies during the mission will explore possible ways to treat or prevent a group of eye and brain changes that can occur during long-duration space travel, called spaceflight associated neuro-ocular syndrome (SANS).
Some researchers suspect the redistribution of bodily fluids in constant weightlessness may increase pressure in the head and contribute to SANS. One study will investigate fluid pressure on the brain while another will examine how the body processes B vitamins and whether supplements can affect how astronauts respond to bodily fluid shifts. Participating crew members will test whether a daily B vitamin supplement can eliminate or ease symptoms of SANS. Specific crew members also will wear thigh cuffs to keep bodily fluids from traveling headward.
Crew members also will complete another set of experiments, called CIPHER (Complement of Integrated Protocols for Human Exploration Research), which measures how multiple systems within the human body change in space. The study includes vision assessments, MRI scans, and other medical exams to provide a complete overview of the whole body’s response to long-duration spaceflight.
Several other studies involving human health and performance are also a part of Crew-11’s science portfolio. Crew members will contribute to a core set of measurements called Spaceflight Standard Measures, which collects physical data and biological samples from astronauts and stores them for other comparative studies. Participants will supply biological samples, such as blood and urine, for a study characterizing how spaceflight alters astronauts’ genetic makeup. In addition, volunteers will test different exercise regimens to help scientists explore what activities remain essential for long-duration journeys.
After landing, participating crew members will complete surveys to track any discomfort, such as scrapes or bruises, acquired from re-entry. The data will help clarify whether mission length increases injury risks and could help NASA design landing systems on future spacecraft as NASA prepares to travel to the Moon, Mars, and beyond.
NASA’s Human Research Program pursues methods and technologies to support safe, productive human space travel. Through science conducted in laboratories, ground-based analogs, and aboard the International Space Station, the program investigates how spaceflight affects human bodies and behaviors. Such research drives NASA’s quest to innovate ways that keep astronauts healthy and mission-ready.

An Update From the 2025 Mars 2020 Science Team Meeting
A behind-the-scenes look at the annual Mars 2020 Science Team Meeting
Members of the Mars 2020 Science Team examine post-impact sediments within the Gardnos impact structure, northwest of Oslo, Norway, as part of the June 2025 Science Team Meeting. NASA/Katie Stack Morgan Written by Katie Stack Morgan, Mars 2020 Acting Project Scientist
The Mars 2020 Science Team gathered for a week in June to discuss recent science results, synthesize earlier mission observations, and discuss future plans for continued exploration of Jezero’s crater rim. It was also an opportunity to celebrate what makes this mission so special: one of the most capable and sophisticated science missions ever sent to Mars, an experienced and expert Science Team, and the rover’s many science accomplishments this past year.
We kicked off the meeting, which was hosted by our colleagues on the RIMFAX team at the University of Oslo, with a focus on our most recent discoveries on the Jezero crater rim. A highlight was the team’s in-depth discussion of spherules observed at Witch Hazel Hill, features which likely provide us the best chance of determining the origin of the crater rim rock sequence.
On the second day, we heard status updates from each of the science instrument teams. We then transitioned to a session devoted to “traverse-scale” syntheses. After 4.5 years of Perseverance on Mars and more than 37 kilometers of driving (more than 23 miles), we’re now able to analyze and integrate science datasets across the entire surface mission, looking for trends through space and time within the Jezero rock record. Our team also held a poster session, which was a great opportunity for in-person and informal scientific discussion.
The team’s modern atmospheric and environmental investigations were front and center on Day 3. We then rewound the clock, hearing new and updated analyses of data acquired during Perseverance’s earlier campaigns in Jezero’s Margin unit, crater floor, and western fan. The last day of the meeting was focused entirely on future plans for the Perseverance rover, including a discussion of our exploration and sampling strategy during the Crater Rim Campaign. We also looked further afield, considering where the rover might explore over the next few years.
Following the meeting, the Science Team took a one-day field trip to visit Gardnos crater, a heavily eroded impact crater with excellent examples of impact melt breccia and post-impact sediment fill. The team’s visit to Gardnos offered a unique opportunity to see and study impact-generated rock units like those expected on the Jezero crater rim and to discuss the challenges we have recognizing similar units with the rover on Mars. Recapping our Perseverance team meetings has been one of my favorite yearly traditions (see summaries from our 2022, 2023, and 2024 meetings) and I look forward to reporting back a year from now. As the Perseverance team tackles challenges in the year to come, we can seek inspiration from one of Norway’s greatest polar explorers, Fridtjof Nansen, who said while delivering his Nobel lecture, “The difficult is that which can be done at once; the impossible is that which takes a little longer.”
