Preparations for Next Moonwalk Simulations Underway (and Underwater)
Students celebrate after a successful performance in the 2024 Student Launch competition at Bragg Farms in Toney, Alabama.NASA NASA has selected 71 teams from across the U.S. to participate in its 25th annual Student Launch Challenge, one of the agency’s Artemis Student Challenges. The competition is aimed at inspiring Artemis Generation students to explore science, technology, engineering, and math (STEM) for the benefit of humanity.
As part of the challenge, teams will design, build, and fly a high-powered amateur rocket and scientific payload. They also must meet documentation milestones and undergo detailed reviews throughout the school year.
The nine-month-long challenge will culminate with on-site events starting on April 30, 2025. Final launches are scheduled for May 3, at Bragg Farms in Toney, Alabama, just minutes north of NASA’s Marshall Space Flight Center in Huntsville, Alabama. Teams are not required to travel for their final launch, having the option to launch from a qualified site. Details are outlined in the Student Launch Handbook.
Each year, NASA updates the university payload challenge to reflect current scientific and exploration missions. For the 2025 season, the payload challenge will again take inspiration from the Artemis missions, which seek to land the first woman and first person of color on the Moon, and pave the way for future human exploration of Mars.
As Student Launch celebrates its 25th anniversary, the payload challenge will include reports from STEMnauts, non-living objects representing astronauts. The STEMnaut crew must relay real-time data to the student team’s mission control via radio frequency, simulating the communication that will be required when the Artemis crew achieves its lunar landing.
University and college teams are required to meet the 2025 payload requirements set by NASA, but middle and high school teams have the option to tackle the same challenge or design their own payload experiment.
Student teams will undergo detailed reviews by NASA personnel to ensure the safety and feasibility of their rocket and payload designs. The team closest to their target will win the Altitude Award, one of multiple awards presented to teams at the end of the competition. Other awards include overall winner, vehicle design, experiment design, and social media presence.
In addition to the engineering and science objectives of the challenge, students must also participate in outreach efforts such as engaging with local schools and maintaining active social media accounts. Student Launch is an all-encompassing challenge and aims to prepare the next generation for the professional world of space exploration.
The Student Launch Challenge is managed by Marshall’s Office of STEM Engagement (OSTEM). Additional funding and support are provided by NASA’s OSTEM via the Next Gen STEM project, NASA’s Space Operations Mission Directorate, Northrup Grumman, National Space Club Huntsville, American Institute of Aeronautics and Astronautics, National Association of Rocketry, Relativity Space, and Bastion Technologies.

Artists Concept of the WASP-77 A b system. A planet swings in front of its star, dimming the starlight we see. Events like these, called transits, provide us with bounties of information about exoplanets–planets around stars other than the Sun. But predicting when these special events occur can be challenging…unless you have help from volunteers.
Luckily, a collaboration of multiple teams of amateur planet-chasers, led by researcher Federico R. Noguer from Arizona State University and researchers from NASA’s Jet Propulsion Laboratory (JPL) and Goddard Space Flight Center (GSFC), has taken up the challenge. This collaboration has published the most precise physical and orbital parameters to date for an important exoplanet called WASP-77 A b. These precise parameters help us predict future transit events and are crucial for planning spacecraft observations and accurate atmospheric modeling.
“As a retired dentist and now citizen scientist for Exoplanet Watch, research opportunities like this give me a way to learn and contribute to this amazingly exciting field of astrophysics,” said Anthony Norris, a citizen scientist working on the NASA-funded Exoplanet Watch project.
The study combined amateur astronomy/citizen science data from the Exoplanet Watch and ExoClock projects, as well as the Exoplanet Transit Database. It also incorporated data from NASA’s Spitzer Space Telescope, the Hubble Space Telescope (HST), the James Webb Space Telescope (JWST), and La Silla Observatory. Exoplanet Watch invites volunteers to participate in groundbreaking exoplanet research, using their own telescopes to observe exoplanets or by analyzing data others have gathered. You may have read another recent article about how the Exoplanet Watch team helped validate a new exoplanet candidate.
WASP-77 A b is a gas giant exoplanet that orbits a Sun-like star. It’s only about 20% larger than Jupiter. But that’s where the similarities to our solar system end. This blazing hot gas ball orbits right next to its star–more than 200 times closer to its star than our Jupiter!
Want a piece of the action? Join the Exoplanet Watch project and help contribute to cutting-edge exoplanet science! Anyone can participate–participation does not require citizenship in any particular country.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
This bar graph shows GISTEMP summer global temperature anomalies for 2023 (shown in yellow) and 2024 (shown in red). June through August is considered meteorological summer in the Northern Hemisphere. The white lines indicate the range of estimated temperatures. The warmer-than-usual summers continue a long-term trend of warming, driven primarily by human-caused greenhouse gas emissions. NASA/Peter Jacobs The agency also shared new state-of-the-art datasets that allow scientists to track Earth’s temperature for any month and region going back to 1880 with greater certainty.
August 2024 set a new monthly temperature record, capping Earth’s hottest summer since global records began in 1880, according to scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York. The announcement comes as a new analysis upholds confidence in the agency’s nearly 145-year-old temperature record.
June, July, and August 2024 combined were about 0.2 degrees Fahrenheit (about 0.1 degrees Celsius) warmer globally than any other summer in NASA’s record — narrowly topping the record just set in 2023. Summer of 2024 was 2.25 F (1.25 C) warmer than the average summer between 1951 and 1980, and August alone was 2.34 F (1.3 C) warmer than average. June through August is considered meteorological summer in the Northern Hemisphere.
“Data from multiple record-keepers show that the warming of the past two years may be neck and neck, but it is well above anything seen in years prior, including strong El Niño years,” said Gavin Schmidt, director of GISS. “This is a clear indication of the ongoing human-driven warming of the climate.”
NASA assembles its temperature record, known as the GISS Surface Temperature Analysis (GISTEMP), from surface air temperature data acquired by tens of thousands of meteorological stations, as well as sea surface temperatures from ship- and buoy-based instruments. It also includes measurements from Antarctica. Analytical methods consider the varied spacing of temperature stations around the globe and urban heating effects that could skew the calculations.
The GISTEMP analysis calculates temperature anomalies rather than absolute temperature. A temperature anomaly shows how far the temperature has departed from the 1951 to 1980 base average.
New assessment of temperature record
The summer record comes as new research from scientists at the Colorado School of Mines, National Science Foundation, the National Atmospheric and Oceanic Administration (NOAA), and NASA further increases confidence in the agency’s global and regional temperature data.
“Our goal was to actually quantify how good of a temperature estimate we’re making for any given time or place,” said lead author Nathan Lenssen, a professor at the Colorado School of Mines and project scientist at the National Center for Atmospheric Research (NCAR).
This visualization of GISTEMP monthly temperatures with the seasonal cycle derived from the Global Modeling and Assimilation Office’s MERRA-2 model compares 2023 (in red) and 2024 (in purple), with a transparent ribbon around each indicating the confidence intervals from the new GISTEMP uncertainty calculation. The white lines show monthly temperatures from the years 1961 to 2022. June, July, and August 2024 combined were about 0.2 degrees Fahrenheit (about 0.1 degrees Celsius) warmer globally than any other summer in NASA’s record — narrowly topping the record set in 2023.NASA/Peter Jacobs/Katy Mersmann The researchers affirmed that GISTEMP is correctly capturing rising surface temperatures on our planet and that Earth’s global temperature increase since the late 19th century — summer 2024 was about 2.7 F (1.51 C) warmer than the late 1800s — cannot be explained by any uncertainty or error in the data.
The authors built on previous work showing that NASA’s estimate of global mean temperature rise is likely accurate to within a tenth of a degree Fahrenheit in recent decades. For their latest analysis, Lenssen and colleagues examined the data for individual regions and for every month going back to 1880.
Estimating the unknown
Lenssen and colleagues provided a rigorous accounting of statistical uncertainty within the GISTEMP record. Uncertainty in science is important to understand because we cannot take measurements everywhere. Knowing the strengths and limitations of observations helps scientists assess if they’re really seeing a shift or change in the world.
The study confirmed that one of the most significant sources of uncertainty in the GISTEMP record is localized changes around meteorological stations. For example, a previously rural station may report higher temperatures as asphalt and other heat-trapping urban surfaces develop around it. Spatial gaps between stations also contribute some uncertainty in the record. GISTEMP accounts for these gaps using estimates from the closest stations.
Previously, scientists using GISTEMP estimated historical temperatures using what’s known in statistics as a confidence interval — a range of values around a measurement, often read as a specific temperature plus or minus a few fractions of degrees. The new approach uses a method known as a statistical ensemble: a spread of the 200 most probable values. While a confidence interval represents a level of certainty around a single data point, an ensemble tries to capture the whole range of possibilities.
The distinction between the two methods is meaningful to scientists tracking how temperatures have changed, especially where there are spatial gaps. For example: Say GISTEMP contains thermometer readings from Denver in July 1900, and a researcher needs to estimate what conditions were 100 miles away. Instead of reporting the Denver temperature plus or minus a few degrees, the researcher can analyze scores of equally probable values for southern Colorado and communicate the uncertainty in their results.
What does this mean for recent heat rankings?
Every year, NASA scientists use GISTEMP to provide an annual global temperature update, with 2023 ranking as the hottest year to date.
Other researchers affirmed this finding, including NOAA and the European Union’s Copernicus Climate Change Service. These institutions employ different, independent methods to assess Earth’s temperature. Copernicus, for instance, uses an advanced computer-generated approach known as reanalysis.
The records remain in broad agreement but can differ in some specific findings. Copernicus determined that July 2023 was Earth’s hottest month on record, for example, while NASA found July 2024 had a narrow edge. The new ensemble analysis has now shown that the difference between the two months is smaller than the uncertainties in the data. In other words, they are effectively tied for hottest. Within the larger historical record the new ensemble estimates for summer 2024 were likely 2.52-2.86 degrees F (1.40-1.59 degrees C) warmer than the late 19th century, while 2023 was likely 2.34-2.68 degrees F (1.30-1.49 degrees C) warmer.
