NASA’s Curiosity Mars rover captured this sand-capped butte, nicknamed “Miraflores,” estimated to be about 20 feet (6 meters) tall, with its Mast Camera, or Mastcam, on June 11, 2026, the 4,923rd Martian day, or sol, of the mission. The butte was left behind as surrounding rock eroded away over time, deepening the broad valley Curiosity

Since their discovery by NASA’s James Webb Space Telescope in 2022, little red dots (LRDs) have been the subject of great interest to astronomers. Understanding the nature of these extremely distant, compact red sources has been a puzzling scientific endeavor. One popular theory is that little red dots are supermassive black holes known as active

Sargassum, a type of brown floating algae, has shifted its range in recent decades, thinning out in the North Atlantic’s Sargasso Sea while proliferating in the tropical Atlantic. That trend, underway since 2011, continued in 2026 as the algae, commonly known as a type of seaweed, reached its annual peak in June across a stretch

The seven-member Expedition 75 crew worked throughout Tuesday on spacesuit checks, eye exams, and exercise research aboard the International Space Station. Earth imagery and lab inventory duties rounded out the day for the orbital residents. NASA has scheduled three spacewalks in August to continue upgrading solar arrays, replace a communications antenna, and connect power and

A.13 Accelerating Earth Solutions (AES) seeks to accelerate the use of Earth-observing satellite measurements in decision-making. Proposals are sought in three general areas: Needs and Opportunities: Identifying critical issues and potential solutions; Solutions Development: Developing solutions for deployment; and Scaling Impact: Scaling the reach and utilization of existing solutions. On or about July 28, 2026,

Over the weekend, Katalyst’s LINK servicing spacecraft experienced issues with attitude control, causing the spacecraft to spin and resulting in sporadic communications. Preliminary investigation shows that two of LINK’s three reaction wheels currently are not operable, and there is some loss of functionality in its cold gas thruster system. LINK is designed to approach, capture, and boost

The IXPE General Observer (GO) Program solicits proposals for investigations in any area of astrophysics related to the Imaging X-ray Polarimetry Explorer (IXPE) (not constrained to IXPE’s prime science areas). Individuals may submit proposals for observations that will advance the IXPE mission science return. Observing proposals may be for “standard,” “Target-of-Opportunity (ToO)”, “Large Program (LP)”
