We’re getting close to launch day for Dragonfly! Engineers at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, have officially kicked off the integration and testing stage for the car-sized, nuclear-powered helicopter bound for Saturn’s largest moon, Titan. According to a press release for APL, after years of designing, tweaking, and testing individual components in laboratories and on computer simulations, various organizations have started testing actual hardware ahead of the mission’s planned 2028 launch.

Mars Plant Growth from Cyanobacteria-Based Fertilizer

You’re the Lead Botanist on the third human mission to Mars whose primary job involves growing food for the crew throughout the long mission. While you’re very familiar with the infamous “poop potatoes” from the 2025 film The Martian, the greatest minds in science had since devised a more efficient, and less messy, method for growing food on Mars: cyanobacteria.



NASA Lays Out Ambitious Plans for Moon Base and Nuclear Mars Mission

NASA has outlined an ambitious strategy to start working on a moon base and send a nuclear-powered spacecraft to Mars by the end of 2028 — leading some observers to wonder whether the timeline was realistic or wise.



Extragalactic Archaeology: A New Method To Understand Galaxy Growth and Evolution

NGC 1365 is also known as the Great Barred Spiral Example. It's a stunning example of its galaxy type. It's about 56 million light-years away in the Fornax Cluster. Researchers have used chemical fingerprints based on oxygen to map out its history.

Galactic archaeology uses chemical fingerprints in the Milky Way to trace its formation and evolution. Now a team of researchers led by the Center for Astrophysics | Harvard and Smithsonian have employed it for the first time in a distant galaxy. This is the first example of extragalactic archaeology, and it relies on help from the powerful Illustris TNG simulations.

Giant Craters May Reveal if Psyche is a Lost Planetary Core

When we think of asteroids, we almost immediately think of giant rocks bouncing around like the iconic chase scene in Empire Strikes Back, and we often hear how they are remnants from the birth of the solar system. While the asteroids that comprise the Main Asteroid Belt of our solar system are not only spread far apart from each other, they are also not all made of rock. One asteroid approximately the size of the State of Massachusetts called 16 Psyche is made of metal, which planetary scientists hypothesize could be the remnants of a protoplanet’s core that didn’t build into a full-fledged planet. But how did such a unique asteroid form?



Parabolic Flight Experiments Delve into Planetary Formation

Planets are thought to grow from dust grains in a protoplanetary disk to form larger and larger objects, eventually creating planets. This illustration from European Southern Observatory is an artist's concept of a typical disk of gas and dust around a newborn star.

What happens in a protoplanetary disk to create planetesimals around a star? We know the general story -- the material begins to clump together and eventually grows from dust grains to rocky bodies capable of sticking together to make planets. But, how does that dust begin the aggregation journey? That's what a research team from the Switzerland wanted to know. So, they did experiments aboard parabolic micro-gravity flights to find an answer.



Rubin Alert Leads to First Follow-Up Observations and Detection of Four Supernovae

NSF NOIRLab has completed end-to-end runs of its ecosystem for following up on alerts from NSF–DOE Vera C. Rubin Observatory. The runs demonstrated how multiple NOIRLab-developed software tools, plus a network of telescopes around the globe, will enable quick follow-up observations of the countless transient objects that Rubin will uncover during its ten-year survey.
