Formas en el cielo europeo: medusas y espirales.
Las formas parecen aparecer de la nada, en La forma espiral ondulada en forma de S en el cielo europeo o Esfera brillante en la costa estadounidense. Estos espectáculos de luces han sido un compañero ordinario de los lanzamientos de cohetes en el pasado, pero a medida que la humanidad aumenta el número de objetos lanzados en el espacio a un ritmo vertiginoso.
Cada vez más personas son testigos del fenómeno por casualidad. Por supuesto, Crecimiento de las redes sociales También abre una amplia gama de testigos interesados.
–No estamos acostumbrados a Ver mucho en el espacio a densidades muy pequeñas (atmosféricas) ”, dice Jonathan McDowell, astrónomo del Centro de Astrofísica de Harvard-Smithsonian, que se refiere a la delgada atmósfera a grandes altitudes.
La semana pasada, un cohete Falcon 9 de SpaceX despegó de Florida, volando hacia el norte para poner un espía militar satelital en la órbita. El fenómeno fue visto por millones de personas del Reino Unido y Europa continental. Las fotos y videos del fenómeno fueron la primera alarmaEntonces más curioso e insensible. La oficina del mapa, el Servicio Meteorológico Nacional del Reino Unido, también compartió imágenes inmediatamente después del lanzamiento y explicó en detalle lo que vemos.
Imágenes lanzadas previamente mencionadas El «fenómeno de Medusa» que acompañó algunas versiones de SpaceX En Florida y California. «Medusa», vista desde la costa norte -estadounidense, es un gran rastro de luz en forma de lágrima, gira y se estira mientras el cohete vuela. Sin embargo, a pesar de las similitudes, los expertos afirman que El metal y la espiral son fenómenos diferentes.
La espiral fantasma Y se formó en forma de murciélagos que siguieron al lanzamiento militar de SpaceX el 24 de marzo se formó después de que el misil terminó y se preparó para caer de la órbita, para regresar a la atmósfera de la tierra y Ingrese la espiral a un baño seguro en el océano, dejando atrás el combustible quemado. Maniobras similares para destruir el cuerpo de un misil son comunes después del lanzamiento.
Falcon 9 fue diseñado para dividirse en dos partes o «etapas». La primera etapa usa nueve motores en la parte inferior del cohete, que se activan despegando y levantando el vehículo de 70 metros (230 metros) del suelo. SpaceX Recyla y reutilizar periódicamente la primera etapa para ahorrar dinero. Sin embargo, la segunda etapa o cohete superior está diseñado para usar su propio motor.
La segunda etapa ofrece la potencia final que lidera la carga de cohetes en línea, ya sea un satélite o una cápsula espacial, con la velocidad necesaria para ingresar a la órbita. Esta velocidad suele ser superior 28.160 km/h. Esto se vio el 24 de marzo al sur de Uppsala (Suecia). Sin embargo, después de la órbita, todavía había combustible en la segunda etapa de Falcon 9, que tuvo que quemarse.
–Quemar combustible a la izquierda es una precaución de seguridad básica Y a menudo una preparación de preparación [romper la órbita] Y regresa al océano «, explica el Dr. Christopher Combs, decano de investigación de la Universidad de Texas. Entonces, la etapa superior del cohete comienza a regresar, empujando el combustible al espacio de la siguiente manera, creando la forma de una espiral que se hincha en el cielo.
Es muy bueno que la gente esté interesada
Tanto las medusas como las espirales necesitan condiciones especiales de iluminación ser visible para el ojo humano. El espectador debe permanecer en la oscuridad mientras el cohete está en el aire, brillando a la luz del sol más allá del horizonte. –Al atardecer o al amanecer es el momento ideal para observarNo en medio de la noche «, dice McDowell sobre los fenómenos que se observan. Los espectáculos de la luz pueden engañar a nuestro cerebro, haciendo que crea que los cohetes están más cerca del suelo de lo que realmente están.
Los observadores pueden creer que El cohete es «Tal vez 10 o 20 millas de altura, cuando en realidad Son 200 millas«El investigador explica.
Combs espera que el público continúe siendo atraído Extraña muestra de luces producidas por Rocket. «Me gusta que la gente esté interesada en el espacio», dice. «Animo a la gente a hacer preguntas, porque hay mucho que ver con mucho que discutir». Los expertos afirman que Es un síntoma positivo cuando los espectadores no son pánico Y piensan en una guerra espacial, pero entiendo el fenómeno y lo disfruto.
«Medusa», as seen from the North American coast, is a large tear-shaped trail of light that spins and stretches as the rocket flies. However, despite the similarities, experts claim that «The metal and the spiral are different phenomena.»
The ghost spiral that formed in the shape of bats following the SpaceX military launch on March 24th formed after the missile ended and prepared to fall from orbit, returning to Earth’s atmosphere and entering the spiral to a safe bath in the ocean, leaving behind the burned fuel. Similar maneuvers to destroy a missile body are common after launch.
Falcon 9 was designed to split into two parts or «stages.» The first stage uses nine engines at the bottom of the rocket, which are activated upon liftoff and lift the 70-meter (230-meter) vehicle off the ground. SpaceX recycles and periodically reuses the first stage to save money. However, the second stage or upper rocket is designed to use its own engine.
The second stage provides the final power that leads the rocket payload into orbit, whether it be a satellite or a spacecraft, with the necessary speed to enter orbit. This speed is usually over 28,160 km/h. This was seen on March 24th south of Uppsala, Sweden. However, after reaching orbit, there was still fuel in Falcon 9’s second stage that needed to be burned.
«Burning fuel is a basic safety precaution and often a preparation step to break orbit and return to the ocean,» explains Dr. Christopher Combs, research dean at the University of Texas. So, the rocket’s upper stage begins to return, pushing the fuel into space in a way that creates the shape of a spiral that expands in the sky.
It is great that people are interested in both jellyfish and spirals, as they require special lighting conditions to be visible to the human eye. The viewer must remain in the dark while the rocket is in the air, shining in the sunlight beyond the horizon. «Sunset or sunrise is the ideal time to observe, not in the middle of the night,» says McDowell about the observed phenomena. Light shows can deceive our brains, making us believe that the rockets are closer to the ground than they actually are.
Observers may think the rocket is «maybe 10 or 20 miles high, when in reality they are 200 miles,» the researcher explains.
Combs hopes that the public will continue to be drawn to the strange display of lights produced by rockets. «I like that people are interested in space,» he says. «I encourage people to ask questions because there is a lot to see and discuss.» Experts claim that it is a positive sign when viewers are not panicking and thinking about space wars, but rather understanding and enjoying the phenomenon.
The shapes seem to appear out of nowhere, such as the spiral wave in the European sky or the bright sphere on the American coast. These light shows have been a common companion to rocket launches in the past, but as humanity increases the number of objects launched into space at a dizzying pace, more and more people are witnessing the phenomenon by chance. Of course, the growth of social networks also opens up a wide range of interested witnesses.
«We are not used to seeing much in space at very low densities (atmospheric),» says Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics, referring to the thin atmosphere at high altitudes.
Last week, a SpaceX Falcon 9 rocket took off from Florida, flying north to put a spy satellite into orbit. The phenomenon was seen by millions of people in the UK and continental Europe. Photos and videos of the phenomenon were the first alarm, then more curious and insensitive. The UK Met Office also shared images immediately after the launch and explained in detail what we see.
Previously mentioned images show the «Medusa phenomenon» that accompanied some SpaceX launches in Florida and California. «Medusa», as seen from the North American coast, is a large tear-shaped trail of light that spins and stretches as the rocket flies. However, despite the similarities, experts claim that «The metal and the spiral are different phenomena.»
