La NASA da la bienvenida a la Tierra a los exploradores lunares de Artemis II, quienes batieron récords

Elegant Figures | 11 April, 2026
Los primeros astronautas en viajar a la Luna en más de medio siglo han regresado a la Tierra tras una misión que ha establecido nuevos récords a bordo del vuelo de prueba Artemis II de la NASA.Los astronautas de la NASA Reid Wiseman, Victor Glover y Christina Koch, y el astronauta Jeremy Hansen de la CSA (Agencia Espacial Canadiense) amerizaron a las 5:07 p.m. PDT (hora del Pacífico) de este viernes frente a la costa de San Diego, completando un viaje de casi 10 días que los llevó a una distancia máxima de 406.771 kilómetros (252.756 millas) de la Tierra."Reid, Victor, Christina y Jeremy: bienvenidos a casa y felicitaciones por un logro verdaderamente histórico. La NASA agradece al presidente Donald Trump y a sus aliados en el Congreso por proporcionar el mandato y los recursos que hicieron posible esta misión y el futuro de Artemis", dijo el administrador de la NASA, Jared Isaacman. "Artemis II demostró una habilidad, valentía y dedicación extraordinarias a medida que la tripulación llevaba a Orion, al Sistema de Lanzamiento Espacial [SLS, por sus siglas en inglés] y a la exploración humana más lejos que nunca. Al ser los primeros astronautas en volar en este cohete y en esta nave espacial, la tripulación aceptó un riesgo considerable al servicio del conocimiento adquirido y el futuro que estamos decididos a construir. La NASA también reconoce las contribuciones de toda la fuerza laboral de esta agencia, así como la de nuestros socios internacionales, cuya pericia y compromiso fueron esenciales para el éxito de esta misión. Con la misión Artemis II completada, la atención se centra ahora con confianza en el ensamblaje de Artemis III y en los preparativos para regresar a la superficie lunar, establecer una base y no volver a abandonar la Luna jamás".Después de su amerizaje en el océano Pacífico, los astronautas fueron recibidos por un equipo combinado de la NASA y el ejército de Estados Unidos, que los asistió para salir de la nave espacial en mar abierto y los transportó en helicóptero hasta el buque USS John P. Murtha para someterse a exámenes médicos iniciales. Se espera que los miembros de la tripulación regresen al Centro Espacial Johnson de la NASA en Houston el sábado 11 de abril.Durante su misión, Wiseman, Glover, Koch y Hansen recorrieron un total de 1.117.659 kilómetros (694.481 millas). Su sobrevuelo lunar los llevó más lejos de lo que jamás han viajado antes los seres humanos, superando el récord de la distancia anterior establecido por los astronautas del Apolo 13 en 1970.La primera tripulación de Artemis despegó a bordo del cohete SLS de la NASA a las 6:35 p.m. del 1 de abril, desde la plataforma de lanzamiento 39B en el Centro Espacial Kennedy de la agencia en Florida. Con casi cuatro millones de kilogramos (8,8 millones de libras) de empuje en el momento del despegue, el cohete de fabricación estadounidense impulsó hacia el espacio a la tripulación ubicada dentro de la nave espacial Orion, situándola en órbita con una precisión milimétrica después de una cuenta regresiva sin contratiempos, dirigida por el equipo de control de lanzamiento de Artemis de la agencia.Durante el primer día en el espacio, los astronautas y los equipos en tierra inspeccionaron la nave espacial --a la que la tripulación ha dado el nombre de Integrity (Integridad en español)-- para confirmar que todos los sistemas funcionaban correctamente antes de hacer el tránsito hacia la Luna. La NASA también desplegó en la órbita terrestre cuatro pequeños satélites CubeSat de sus socios internacionales.En el segundo día del vuelo de prueba, con todos los sistemas listos ("Go" en el argot astronáutico), el módulo de servicio de Orion encendió su motor principal, situando a los astronautas en una trayectoria que los llevó a 6.545 kilómetros (4.067 millas) por encima de la superficie lunar en su aproximación más cercana."La tripulación de Artemis II ya está en casa. Los sistemas de reentrada, descenso y aterrizaje funcionaron tal como fueron diseñados, y la prueba final se completó según lo previsto. Este momento pertenece a las miles de personas, de catorce países distintos, que construyeron este vehículo, lo sometieron a pruebas y depositaron su confianza en él. Su trabajo protegió cuatro vidas humanas que viajaban a 40.233 kilómetros (25.000 millas) por hora, y las trajo de regreso a la Tierra sanas y salvas", dijo Amit Kshatriya, administrador asociado de la NASA. "Artemis II ha validado el vehículo, los equipos, la arquitectura y la colaboración internacional que llevarán de nuevo a la humanidad a la superficie lunar. Reid, Victor, Christina y Jeremy llevaron las esperanzas de este mundo más lejos de lo que los seres humanos han viajado en más de medio siglo. Hace 53 años, la humanidad dejó la Luna. Esta vez, hemos regresado para quedarnos. El futuro es nuestro para conquistarlo".

Climate Change? L’Addition, s’il vous plaît! Why Damage Calculation Matters in Climate Change Litigation

Climate Law Blog | 10 April, 2026
The number of climate change lawsuits brought before domestic, regional, and international courts is growing at an unprecedented pace, with courts increasingly being asked to hold governments and corporations accountable for the harms associated with our warming planet. Most of the focus in the scholarship so far has been on whether such cases can be brought and how to navigate procedural hurdles like jurisdiction and causation. Far less discussed is a third critical element: how much should be paid for climate damage, i.e. the"quantum" of damages. This post explores the often overlooked issue of calculating damages in climate change lawsuits, drawing on insights from an award-winning research paper (2023 Galli Prize). By comparing approaches in the U.S. and abroad, it shows how economics can help align legal damages with the true costs of climate change and improve the deterrence effect of climate laws.

Synergistic Integration of Flood Inundation Modeling Methods

The Plainspoken Scientist | 10 April, 2026
Flood inundation models are tools that predict where water flows, how deep it gets, how fast it moves and how long it remains during a flood event. But despite recent advances in flood inundation models, some flood modeling paradigms are being used beyond their range of applicability rather than leveraging the strengths of different methods. A new article in Review of Geophysics explores the...

New Perspective of Home

Elegant Figures | 10 April, 2026
Seen during Artemis II's lunar flyby on April 6, 2026, the Moon and Earth align in the same frame, each partially illuminated by the Sun. The Moon's surface appears in sharp detail in the foreground, while Earth sits much farther away, smaller and softly lit in the background. A faint reflection in the spacecraft window is also visible, subtly overlaying the scene. Though their phases differ, both are shaped by the same sunlight, revealing the geometry of the Sun-Earth-Moon system from deep space.

Questions about accessibility at EGU26? Useful resources for parents, disabled attendees and more!

EGU Geolog | 10 April, 2026
The annual EGU General Assembly is a wonderful chance to gather together with friends and colleagues to discuss recent scientific work, plan new projects and develop your career, but a scientific meeting, especially one the size and length of time of the General Assembly is not an equally accessible experience for everyone. With this in mind over the years EGU have developed a range of resources aimed at increasing the accessibility of the meeting to a more diverse group of people, but if you are unsure what those resources are, we have gathered many of them in this blog to help you find them, whether you are a person attending with children, with a disability, with specific religious requirements, travel challenges or any other reason, to help you have the best meeting possible!

Alaska’s Wildfires Heat the Planet, but Canada’s Cool It

When it comes to wildfires, the story may seem straightforward: As forests burn, they release greenhouse gases like carbon dioxide, carbon monoxide, and methane that warm the planet. But in the far northern parts of North America, wildfires don't always follow the same script. In a new study published in Nature Geoscience, researchers found that forest fires in Alaska tend to have a warming...
