Invention Challenge Brings Student Engineers to NASA JPL

Now in its 26th year, the event brings teams of middle and high school students to the lab to compete with home-built contraptions.

Teenagers wielding power tools and plywood demonstrated their engineering prowess at the annual Invention Challenge at NASA’s Jet Propulsion Laboratory in Southern California on Friday. Also in evidence: lots of small motors, 3D-printed gears, PVC pipe, and duct tape.

First held at JPL in 1998, the event pits middle and high school teams against each other as they try to get handmade devices to accomplish a task that changes annually. For this year’s challenge, dubbed the “Bucket Brigade Contest,” teams needed to create devices capable of moving about 2 gallons (8 liters) of water from a holding reservoir into a bucket about 16 feet (5 meters) away in 60 seconds while satisfying a long list of rules.

In all, 18 teams of students from middle and high schools across Los Angeles and Orange counties competed. First place went to Arcadia High School’s Team Still Water, which completed the task in just 6.45 seconds. Mission Viejo High’s Team Senior Citizens was close behind, finishing in 6.71 seconds. The Samo Seals of Santa Monica High came in third, at 9.18 seconds.

Five teams from outside the area — four from schools in Colorado and Massachusetts and one involving professional engineers — were invited to compete as well. Of those, the team led by retired JPL engineer Alan DeVault’s Team “Trial and Error Engineering” came in first (a repeat from last year). And “Team 6” from Pioneer Charter School of Science in the Boston area took second place (also a repeat performance from 2024). No team qualified for third place.

Judges named Team Clankers from Mission Viejo High most artistic, Team 6 from Pioneer Charter School of Science most unusual, and Team Winning Engineering Team (WET) from Temple City High most creative.

The event was supported by dozens of volunteers from JPL staff. JPL Fire Chief Dave Dollarhide, familiar with a bucket brigade, was a guest judge.

NASA Wins Second Emmy Award for 2024 Total Solar Eclipse Broadcast

NASA’s broadcast of the April 8, 2024, total solar eclipse has won an Emmy Award for Excellence in Production Technology.

At the 76th Technology & Engineering Emmy Awards on Dec. 4, in New York City, the Academy of Television Arts & Sciences announced the win. Walt Lindblom and Sami Aziz accepted the award on behalf of the agency. For the broadcast, Lindblom served as the coordinating producer and Aziz served as the executive producer.

“By broadcasting the total solar eclipse, this team brought joy and wonder for our Sun, Moon, and Earth to viewers across America and the world,” said Will Boyington, associate administrator for the Office of Communications at NASA Headquarters in Washington. “Congratulations to the production team, whose efforts demonstrate the hard work and dedication to the sharing the marvel that makes our solar system something we strive to understand.” 

NASA’s live broadcast coverage of the 2024 total solar eclipse was the most complex live project ever produced by the agency. In total, NASA’s eclipse broadcasts garnered almost 40 million live and replay views across its own distribution channels, including on NASA+, the agency’s free streaming service. Externally, the agency’s main broadcast was picked up in 2,208 hits on 568 channels in 25 countries.

“Our unique place in the solar system allows us on Earth to witness one of the most spectacular science shows nature has to offer. NASA’s production team captured the action every step of the way across the path of totality, including the rare glimpse of the Sun’s corona,” said Nicky Fox, associate administrator for science at NASA Headquarters. “Congratulations to the NASA team for successfully showing the 2024 total solar eclipse through the eyes of NASA for the whole world to experience together.”

The broadcast spanned three hours, showcasing the eclipse across seven American states and two countries. From cities, parks, and stadiums, 11 hosts and correspondents provided on air commentary, interviews, and live coverage. Viewers tuned in from all over the world, including at watch parties in nine locations, from the Austin Public Library to New York’s Times Square. An interactive “Eclipse Board” provided real time data analysis as the Moon’s shadow crossed North America.

Live feeds from astronauts aboard the International Space Station and NASA’s WB-57 high-altitude research aircraft were brought in to provide rare and unique perspectives of the solar event. To make this possible, NASA deployed and enabled 67 cameras, 6 NASA Wide Area Network control rooms, 38 encoders, and 35 decoders. The team coordinated 20 live telescope feeds which represented 12 locations across the path of totality.

NASA’s eclipse broadcast won another Emmy award earlier this year at the 46th Annual News & Documentary Emmy Awards for Outstanding Live News Special. Additionally, the show received an Emmy nomination for Outstanding Show Open or Title Sequence – News. NASA’s eclipse communication and broadcast efforts also won two Webby Awards and two Webby People’s Voice Awards.

Testing Drones for Mars in the Mojave Desert

Researchers from NASA’s Jet Propulsion Laboratory monitor a research drone in this September 2025 photo. This flight occurred in Dumont Dunes, an area of the Mojave Desert, as part of a larger test campaign to develop navigation software that would guide future rotorcraft on Mars. The work was among 25 projects funded by NASA’s Mars Exploration Program this past year to push the limits of future technologies.

Whether it’s new navigation software, slope-scaling robotic scouts, or long-distance gliders, the technology being developed by the Mars Exploration Program envisions a future where robots can explore all on their own — or even help astronauts do their work.

Hubble Spots a Storm of New Stars

This NASA/ESA Hubble Space Telescope image features a stormy and highly active spiral galaxy named NGC 1792. Located over 50 million light-years from Earth in the constellation Columba (the Dove), the bright glow of the galaxy’s center is offset by the flocculent and sparkling spiral arms swirling around it.

NGC 1792 is just as fascinating to astronomers as its chaotic look might imply. Classified as a starburst galaxy, it is a powerhouse of star formation, with spiral arms rich in star-forming regions. In fact, it is surprisingly luminous for its mass. The galaxy is close to a larger neighbor, NGC 1808, and astronomers think the strong gravitational interaction between the two stirred up the reserves of gas in this galaxy. The result is a torrent of star formation, concentrated on the side closest to its neighbor, where gravity has a stronger effect. NGC 1792 is a perfect target for astronomers seeking to understand the complex interactions between gas, star clusters, and supernovae in galaxies.

Hubble studied this galaxy before. This new image includes additional data collected throughout 2025, providing a deeper view of the tumultuous activity taking place in the galaxy. Blossoming red lights in the galaxy’s arms mark Hydrogen-alpha (H-alpha) emission from dense clouds of hydrogen molecules. The newly forming stars within these clouds shine powerfully with ultraviolet radiation. This intense radiation ionizes the hydrogen gas, stripping away electrons which causes the gas to emit H-alpha light. H-alpha is a very particular red wavelength of light and a tell-tale sign of new stars.
