Battlestar Galactica meets FTL in this just-announced "story-rich tactical roguelite" from the makers of Crying Suns.

Russia launched its Bion-M No. 2 biosatellite today (Aug. 20), sending 75 mice, 1,000 fruit flies and other organisms to orbit to learn more about the health effects of spaceflight.

A fireball exploded into life in the skies above Japan on Aug. 19, briefly turning night to day before fragmenting close to the horizon.

Viking 1 was launched by a Titan-Centaur rocket from Complex 41 at Cape Canaveral Air Force Station at 5:22 p.m. EDT on Aug. 20, 1975, to begin a half-billion mile, 11-month journey through space to explore Mars. The 4-ton spacecraft went into orbit around the red planet in mid-1976 and landed on Mars on July 20, 1976.

A Titan-Centaur rocket carrying the Viking 1 spacecraft launches from Complex 41 at Cape Canaveral Air Force Station on Aug. 20, 1975. Viking 1 touched down on the red planet on July 20, 1976, becoming the first truly successful landing on Mars. Viking 1 was the first of a pair of complex deep space probes that were designed to reach Mars and to collect evidence on the possibility on life on Mars.

NASA’s exploration of Mars continues, with rovers exploring the planet’s surface and spacecraft studying from orbit. The agency’s Artemis missions will also lay the groundwork for the first crewed missions to Mars.

A 1989 experiment offered the promise of nuclear fusion without the need for high temperatures, but this "cold fusion" was quickly debunked. Now, some of the techniques involved have been resurrected in a new experiment that could actually improve efforts to achieve practical fusion power

Acting NASA Administrator Sean Duffy says it's time for the agency to focus on the moon and Mars, not the "smorgasbord of priorities," like climate science, the agency has been directing its resources.

After five years, Pragmata could have been unambitious, but instead, it's a fascinating and innovative sci-fi game with heaps of potential.

An AI model trained on years of data from NASA’s Solar Dynamics Observatory can predict the sun’s future appearance and potentially flag dangerous solar flares

Bring NASA Science into Your Library!

Calling all librarians! NASA sponsors dozens of research projects that need help from you and the people in your community. These projects invite everyone who’s interested to collaborate with scientists, investigating mysteries from how star systems form to how our planet sustains life. You can help by making observations with your cell phone or by studying fresh data on your laptop from spacecraft like the James Webb Space Telescope. You might discover a near-Earth asteroid or a new food option for astronauts.  Participants learn new skills and meet scientists and other people around the world with similar interests. 

Interested in sharing these opportunities with your patrons? Join us on August 26, 2025 at 1 p.m. EST for a 1-hour online information session.  A librarian and a participatory science professional will provide you with a NASA Citizen Science Librarian Starter Kit and answer all your questions. The kit includes everything you need to host a NASA Science Program for patrons of all ages. 

• Editable poster to advertise event
• Event prep guide (for the host and for the space)
• Community connection ideas 
• Editable event agenda
• Handout for participants

Scan the QR code above or go to https://shorturl.at/tKfTt to register for the session.
