Set to track sea levels across more than 90% of Earth’s ocean, the mission must first get into orbit. Here’s what to expect. Sentinel-6B, an ocean-tracking satellite jointly developed by NASA and ESA (European Space Agency), is ready to roll out to the launch pad, packed into the payload fairing of a SpaceX Falcon 9 […]

Data from Sentinel-6B will continue a decades-long record of sea surface height, helping to improve coastal planning, protect critical infrastructure, and advance weather forecasts. With launch set for no earlier than 12:21 a.m. EST Monday, Nov. 17, Sentinel-6B is the latest satellite in a series of spacecraft NASA and its partners have used to measure […]

NASA will provide live coverage of prelaunch and launch activities for Sentinel-6B, an international mission delivering critical sea level and ocean data to protect coastal infrastructure, improve weather forecasting, and support commercial activities at sea. Launch is targeted at 12:21 a.m. EST, Monday, Nov. 17 (9:21 p.m. PST, Sunday, Nov. 16) aboard a SpaceX Falcon […]

This image released on June 30, 2025, combines data from NASA’s James Webb Space Telescope and NASA’s Chandra X-ray Observatory to visualize dark matter. Researchers used Webb’s observations to carefully measure the mass of the galaxy clusters shown here as well as the collective light emitted by stars that are no longer bound to individual […]

NASA’s Glenn Research Center in Cleveland has earned 2025 R&D 100 Awards for developing a system that delivers high-speed internet for space and co-inventing technology for a new class of soft magnetic nanocrystalline materials designed to operate at extreme temperatures. This brings NASA Glenn’s total to 130 R&D 100 Awards. High-Rate Delay Tolerant Networking NASA […]

Stars of all ages are on display in this NASA/ESA Hubble Space Telescope image of the sparkling spiral galaxy called NGC 6000, located 102 million light-years away in the constellation Scorpius. NGC 6000 has a glowing yellow center and glittering blue outskirts. These colors reflect differences in the average ages, masses, and temperatures of the […]

A pair of NASA spacecraft ultimately destined for Mars will study how its magnetic environment is impacted by the Sun. The mission also will help the agency prepare for future human exploration of Mars. NASA’s ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) spacecraft launched at 3:55 p.m. EST, Thursday, aboard a Blue Origin New […]

By Susanne P. Schwenzer, Professor of Planetary Mineralogy at The Open University, U.K. Earth planning date: Friday, Oct. 31, 2025 I am writing this blog and it’s still daytime — and I am looking forward to accompanying one of my favorite kids to trick-and-treating afterwards. That’s a new feeling for me because I am usually […]

Written by William Farrand, Senior Research Scientist, Space Science Institute Earth planning date: Friday, Oct. 24, 2025 Curiosity has successfully drilled its 44th hole on Mars, which is a major milestone in our investigation of the enigmatic “boxwork unit,” a region of resistant ridges surrounding pits or “hollows” of less-resistant rock. The drilling took place […]

Written by Catherine O’Connell-Cooper, APXS Payload Uplink/Downlink Lead, University of New Brunswick Earth planning date: Friday, Oct. 17, 2025 Curiosity has been investigating the “boxwork unit” for several months now. Readers might remember we drilled at the edge of the boxwork at “Altadena,” back in June. Since then, we have driven just under a kilometer […]

Written by Diana Hayes, Graduate Student at York University, Toronto Earth planning date: Friday, Oct. 10, 2025 This week was one of seasonal changes and milestones for the mission. As was mentioned several weeks ago, Mars has now moved out of its “cloudy season” and is transitioning into the “dusty season” as the planet moves […]

Written by Michelle Minitti, MAHLI Deputy Principal Investigator at Framework Earth planning date: Friday, Oct. 3, 2025 Before Curiosity landed 13 years ago, the science team eyed all the geologic wonders scattered across the flanks of Mount Sharp and looked forward to the day when we could put the rover to work on them. We […]

NASA astronaut Jonny Kim took this photo on July 23, 2025, as the International Space Station orbited 259 miles above a cloudy Pacific Ocean southwest of Mexico. Visible in the image is the 57.7-foot-long Canadarm2 robotic arm, which extends from a data grapple fixture on the International Space Station’s Harmony module. Attached to its latching […]

Perseverance Encounters a Possible Meteorite Written by Candice Bedford, Research Scientist at Purdue University Oct. 1, 2025 During the rover’s recent investigation of the bedrock at “Vernodden,” Perseverance encountered an unusually shaped rock about 80 centimeters across (about 31 inches) called “Phippsaksla.” This rock was identified as a target of interest based on its sculpted, […]

NASA’s Technology Transfer Office invites entrepreneurs, innovators, and creative thinkers to apply NASA’s patented technologies to practical applications. Participants will select an existing NASA patent and develop a business or product concept that will be evaluated based on value proposition, business model viability, development feasibility, and quality of presentation. Entries should clearly demonstrate creativity, feasibility, […]

Astronomers using the European Space Agency’s XMM-Newton space observatory and the LOFAR telescope have definitively spotted an explosive burst of material thrown out into space by another star – a burst powerful enough to strip away the atmosphere o…
First confirmed sighting of explosive burst on nearby star

by Kat Troche of the Astronomical Society of the Pacific September 2025 marks ten years since the first direct detection of gravitational waves as predicted by Albert Einstein’s 1916 theory of General Relativity. These invisible ripples in space were first directly detected by the Laser Interferometer Gravitational-Wave Observatory (LIGO). Traveling at the speed of light […]

NASA and Blue Origin are reopening media accreditation for the launch of the agency’s ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) mission. The twin ESCAPADE spacecraft will study the solar wind’s interaction with Mars, providing insight into the planet’s real-time response to space weather and how solar activity drives atmospheric escape. This will be […]

NASA, along with leaders from global space agencies and government representatives worldwide, convened on Monday to further the implementation of the Artemis Accords — practical principles designed to guide the responsible exploration of the Moon, Mars, and beyond. The meeting was held during the 76th International Astronautical Congress (IAC) taking place in Sydney. In opening […]
