The Southern Patagonian Icefield is the largest expanse of ice in the Southern Hemisphere outside of Antarctica. The mass of glacial ice extends hundreds of kilometers along the spine of the Andes, feeding dozens of dynamic outlet glaciers that grind their way down from higher elevations. Many of these rivers of ice terminate in the sea or in proglacial lakes.

Read this release in English here.La NASA dio el martes otro paso hacia una de las misiones tripuladas más complejas de la historia reciente al ofrecer nuevos detalles sobre Artemis III y anunciar a los cuatro miembros principales de la tripulación y a un suplente para este vuelo de prueba. En 2027, la misión llevará a cabo una serie de exigentes pruebas cerca de la Tierra que son esenciales para Artemis IV, la primera misión tripulada al Polo Sur lunar, prevista para 2028.En la misión Artemis III, el cohete SLS (por las siglas en inglés de Sistema de Lanzamiento Espacial) de la agencia lanzará la nave espacial Orion y a su tripulación desde el Centro Espacial Kennedy de la NASA, en Florida, a la órbita terrestre baja. Tras las verificaciones de los sistemas de Orion, la nave espacial demostrará por primera vez sus capacidades de encuentro y acoplamiento con versiones de prueba de uno o ambos sistemas comerciales estadounidenses de aterrizaje humano, que están siendo desarrollados por Blue Origin y SpaceX. Esta misión, cuidadosamente coreografiada, incluye una espectacular campaña de múltiples lanzamientos de los cohetes más potentes del mundo y pondrá a prueba el equipamiento integrado entre Orion y los módulos de aterrizaje, así como las interfaces de los sistemas, el software, la propulsión y las comunicaciones.Los astronautas asignados a la tripulación son los siguientes:

A period of unsettled weather brought scattered showers and thunderstorms to California's Bay Area on May 27, 2026. That afternoon, a break in the clouds left downtown San Francisco and nearby communities beneath mostly cloud-free skies, allowing an astronaut aboard the International Space Station to take this photograph.

Of all the rock quarries in our hills since Oakland was founded, I'll focus today on what may be the most striking one. It's had several different names, but I call it the Davie quarry because for nearly a century it's been a memorial to one of Oakland's most colorful mayors, John L. Davie, and is home to the Davie Tennis Stadium.

About an hour's drive east of Dubai's gleaming towers and artificial islands, a quieter, more natural landscape takes shape. At the far northern edge of the Rub' al Khali, a saffron-colored sand sea laps against the Al-Hajar Mountains. A series of pale ridges rises finlike from the desert plain, with the largest--Jabal al F?yah--standing 412 meters (1,352 feet) above sea level.

As Earth's oceans warm, microscopic marine organisms are experiencing increasing stress due to a lack of vital nutrients. A new study combining NASA satellite observations, ocean surveys, and genetic testing on marine microorganisms suggests that warming ocean waters are limiting nutrient availability across much of the global ocean, with the potential to reshape marine ecosystems.

In May and June of most years, NASA satellites typically begin to detect large numbers of wildland fires throughout the Top End and Arnhem Land regions of Australia's Northern Territory. On some days, especially in the afternoon, the blazes can resemble sizable wildfires in satellite imagery, spreading widely and producing expansive smoke plumes.

One of the first images transmitted back to Earth from the Artemis II mission was a stunner. In a single image, Earth's full disk appears amid celestial phenomena that illustrate its place in the solar system. And although the visible hemisphere appears to be awash in sunlight, it is actually lit by moonlight. The astronauts' vantage point provided a rare opportunity to capture nighttime features--most notably lights from human habitation--from a new perspective.
