Artemis 2 y Artemis 1

·55 min·4 clips

Four astronauts are now flying around the moon on Artemis 2, the first human deep-space mission in over half a century.

1. 'Flash Diario de El Siglo 21 es Hoy' covers the April 2026 launch of Artemis 2, the first crewed journey beyond low Earth orbit since the Apollo program ended in 1972. 2. Host Félix Riaño is the sole presenter; he is identified on social media as @locutorco and produces the show on technology, science, and digital culture. 3. The episode's core mission is to explain Artemis 2 in real time while contextualizing it with a republished 2022 episode on Artemis 1. 4. The Artemis 2 crew is named as Reid Wiseman, Victor Glover, Christina Koch — noted as the first woman on a lunar-distance mission — and Jeremy Hansen, the first Canadian to travel beyond low Earth orbit. 5. The SLS rocket is described as 98 meters tall, consuming more than 2.6 million liters of fuel, reaching supersonic speeds within minutes of launch. 6. The mission profile involves three phases: Earth orbital checkout of all systems, a translunar injection engine burn, and a free-return trajectory that uses lunar gravity to slingshot the capsule back without requiring engine propulsion. 7. Félix explains that the free-return trajectory type was last used during the Apollo program and provides a safety margin if any system fails during the lunar pass. 8. During the flight, a temporary communications loss occurred where Earth-based mission control could not hear the astronauts for several minutes. 9. The toilet system aboard Orion reported errors — the first time this specific system was tested in deep space — and Félix notes that on a 10-day mission, this is a significant problem. 10. Astronauts practiced manual navigation, approaching within 10 meters of a rocket section using only visual judgment without distance sensors, a precision maneuver with no margin for error. 11. The crew will reach a distance of more than 406,000 km from Earth — farther than any previous crewed mission. 12. Astronauts will observe a solar eclipse from space and photograph the dark side of the Moon, capturing an updated version of the famous Earthrise photograph. 13. Artemis 2 was originally scheduled for 2024, with the crewed lunar landing (Artemis 3) planned for 2025; both have slipped at least two years. 14. China has announced a crewed lunar landing target of 2030, creating geopolitical pressure on the US Artemis timeline. 15. Félix draws a direct parallel between Artemis 2 and Apollo 8 (1968), noting both were crewed lunar flybys without landing, but argues the goals differ: Apollo 8 sought Cold War victory, Artemis 2 targets permanent lunar presence. 16. The republished Artemis 1 segment covers the November 16, 2022 launch of the uncrewed Orion capsule after four prior attempts — scrubbed for engine malfunction, fuel leak, Hurricane Ian, and Tropical Storm Nicole. 17. Artemis 1 flew 400,000 km from Earth — a record for any capsule certified for crewed spaceflight — and returned at 40,000 km/h (32 times the speed of sound). 18. The Orion heat shield withstood approximately 2,800 degrees Celsius during atmospheric reentry, described as roughly half the surface temperature of the Sun. 19. Félix explains the historical context of why humans did not return to the Moon after 1972: the fall of the Soviet Union removed the geopolitical incentive, and NASA pivoted attention and resources toward Mars and the International Space Station. 20. Listeners interested in space exploration, NASA history, geopolitics of the space race with China, and accessible science communication in Spanish will find the episode comprehensive; those seeking breaking news or technical engineering depth may find it introductory.
