Wind-Sculpted Landscapes: Investigating the Martian Megaripple ‘Hazyview’

Written by Noah Martin, Ph.D. student and Candice Bedford, Research Scientist at Purdue University While much of Perseverance’s work focuses on ancient rocks that record Mars’ long-lost rivers and lakes, megaripples offer a rare opportunity to examine processes that are still shaping the surface today. Megaripples are sand ripples up to 2 meters (about 6.5 feet) tall that are mainly…

NASA Johnson’s 2025 Milestones

NASA’s Johnson Space Center in Houston closed 2025 with major progress across human spaceflight, research, and exploration. From Artemis II mission preparations to science aboard the International Space Station, teams at Johnson helped prepare for future missions to the Moon and, ultimately, Mars. Orion Stacked for Artemis II, Orion Mission Evaluation Room Unveiled  NASA’s Artemis II Orion spacecraft with its…

NASA Shares SpaceX Crew-12 Assignments for Space Station Mission

As part of NASA’s SpaceX Crew-12 mission, four crew members from three space agencies will launch no earlier than Sunday, Feb. 15, 2026, to the International Space Station for a long-duration science expedition. NASA astronauts Jessica Meir and Jack Hathaway will serve as spacecraft commander and pilot, respectively, and will be accompanied by ESA (European Space Agency) astronaut Sophie Adenot and Roscosmos cosmonaut Andrey…

Water Droplet Science

NASA astronaut Don Pettit demonstrates electrostatic forces using charged water droplets and a knitting needle made of Teflon. This series of overlapping frames from Feb. 19, 2025, displays the unique attraction-repulsion properties of Teflon and charged droplets, similar to how charged particles from the Sun behave when they come in contact with Earth’s magnetic field. Highly energetic particles from space that collide…

Apollo 8: Christmas on the Moon

NASA’s Wideband Technology Demo Proves Space Missions are Free to Roam

Just like your cellphone stays connected by roaming between networks, NASA’s Polylingual Experimental Terminal, or PExT, technology demonstration is proving space missions can do the same by switching seamlessly between government and commercial communications networks. NASA missions rely on critical data to navigate, monitor spacecraft health, and transmit scientific information back to Earth, and this game-changing technology could provide multiple benefits…

Betelgeuse and the Crab Nebula: Stellar Death and Rebirth

What happens when a star dies? In 2019, Betelgeuse dimmed in brightness, sparking speculation that it may soon explode as a supernova. While it likely won’t explode quite yet, we can preview its fate by observing the nearby Crab Nebula. A view of the constellations Orion and Taurus, along with notable features: Betelgeuse in Orion, and Aldebaran and the Crab Nebula in Taurus.…

Hubble Glimpses Galactic Gas Making a Getaway

A sideways spiral galaxy shines in this NASA/ESA Hubble Space Telescope image. Located about 60 million light-years away in the constellation Virgo (the Maiden), NGC 4388 is a resident of the Virgo galaxy cluster. This enormous cluster of galaxies contains more than a thousand members and is the nearest large galaxy cluster to the Milky Way. NGC 4388 appears to tilt at…

Curiosity Blog, Sols 4743-4749:  Polygons in the Hollow

Written by Lucy Lim, Planetary Scientist at NASA’s Goddard Space Flight Center Earth Planning Date: Friday, Dec. 12, 2025 The weekend drive starting from the “Nevado Sajama” drill site brought Curiosity back into the “Monte Grande” boxwork hollow. We’ve been in this hollow before for the “Valle de la Luna” drill campaign, but now that the team has seen the results…

Moon Mascot: NASA Artemis II ZGI Design Challenge

Whose Moon Mascot design will join the Artemis II astronauts on their historic voyage around the Moon in early 2026? Between March 7 and Jun. 16, 2025, NASA worked with crowdsourcing company Freelancer to seek design ideas from global creators for a zero gravity indicator that will fly aboard the agency’s Artemis II test flight. Zero gravity indicators are small, plush items…
