El Siglo 21 es Hoy

Por NASA Podcast #Recomendado La idea de viajar a Marte ha estado presente durante mucho tiempo, pero no ha sido hasta hace poco que se han hecho los primeros pasos reales hacia lograr esto. Ahora, con la ayuda de los expertos de la NASA, estamos más cerca de ver un diseño de nave espacial que llevaría a los humanos entre la Tierra y Marte. Pero, ¿cómo lograríamos esto? Hoy en día tenemos la ventaja de contar con la experiencia de los ingenieros de la NASA, quienes han pasado años desarrollando y diseñando naves espaciales. En una entrevista con un ingeniero de la NASA, nos explicó cómo se está preparando para la misión. El ingeniero explicó que están a punto de diseñar una nave espacial con la suficiente potencia para lograr la velocidad y la resistencia necesaria para transportar a los seres humanos a través del espacio. La nave espacial tendría que tener la capacidad de resistir los efectos de una inmersión prolongada en el espacio y también necesitaría ser lo suficientemente re...

The puffs and pings of the rover’s Gaseous Dust Removal Tool (gDRT) were collected using a microphone on the rover’s chassis. The gRDT has a tank of nitrogen gas and is used during sample collection to blow the dust away and reveal the fresh rock surface underneath.

Since he was 7 years old, Ken knew he wanted to become an astronaut. In his astronaut career, he participated in many exciting missions, including an extended stay on the International Space Station. What did he eat? How did he feel when he came home? Now a leader in NASA’s Human Exploration and Operations Mission Directorate, Ken currently works on plans for sending astronauts to the Moon through the Artemis program, with an eventual goal of Mars.

Por NASA Podcast #Recomendado Tweet Listen to NASA’s Ingenuity Mars Helicopter in Flight For the first time, a spacecraft on another planet has recorded the sounds of a separate spacecraft. NASA’s Perseverance Mars rover used its SuperCam microphone to listen to the Ingenuity helicopter on April 30, 2021 as it flew on Mars for the fourth time. With Perseverance parked 262 feet (80 meters) from the helicopter’s takeoff and landing spot, the mission wasn’t sure if the microphone would pick up any sound of the flight. Even during flight when the helicopter’s blades are spinning at 2,537 rpm, the sound is greatly muffled by the thin Martian atmosphere. It is further obscured by Martian wind gusts during the initial moments of the flight. Listen closely, though, and the helicopter’s hum can be heard faintly above the sound of those winds. Scientists made the audio, which is recorded in mono, easier to hear by isolating the 84 hertz helicopter blade sound, reducing the frequencies bel...
