Serie De Imágenes Tomadas En El Transcurso Del Año 2020 Para Mostrar El Aumento De Tamaño Aparente

Increíble fotografía de la conjuncion de Jupiter y Saturno que nos acaban de compartir. Este tipo de fenómeno ocurre entre 4 y 5 veces en 100 años, pero es inusual ver los planetas tan cercas como en esta ocasión. La última vez que se vieron así de cerca fue hace más de 400 años.

Tránsito de la Estación Espacial Tiangong

Se utilizo un refractor de 8 ′′ a lo largo del Mar Mediterráneo, para este tránsito solar de 1/2 segundo de la nueva Estación Espacial Tiangong de China, que incluye los 3 módulos con sus paneles solares y sin duda el brazo robótico.

Laying the Groundwork for a New Generation of Commercial Supersonic Aircraft

Cabin crew, prepare for takeoff. Engines roar; speed increases. You sip a cold beverage as the aircraft accelerates quietly past Mach 1 or around 600 mph. There’s no indication you’re flying over land faster than the speed of sound except when you glance at your watch upon arrival and see you’ve reached your destination in half the time. You leisurely walk off the plane with ample time to explore, finish a final report or visit a familiar face. This reality is closer than you think.

We’re on a mission to help you get to where you want to go in half the time. Using our single-pilot X-59 Quiet SuperSonic Technology (QueSST) research aircraft, we will provide rule-makers the data needed to lift current bans on faster-than-sound air travel over land and help enable a new generation of commercial supersonic aircraft.

The X-59 QueSST is unique in shape. Each element of the aircraft’s design will help reduce a loud sonic boom, typically produced by conventional supersonic aircraft, to a gentle sonic thump, making it quieter for people on the ground. To prove the quiet technology works, we will fly the X-59 over select U.S. communities to gauge the public’s response to the sound.

We are working with Lockheed Martin in Palmdale, California, to manufacture the X-59 and are making significant progress, despite the pandemic.

We finished the majority of work on the wing and closed its interior, marking the halfway point on construction of the aircraft. 

The X-59 team at Lockheed Martin completed the final touches by fastening skins to the wing. A special sealant is applied so that fuel can be carried in the wings of the aircraft.

Moving at a steady pace, technicians continue to work on many parts of the aircraft simultaneously. The forebody section of the aircraft will carry the pilot and all the avionics needed to fly the aircraft.

Because of the X-59’s long nose, the pilot will rely on an eXternal Vision System (XVS), rather than a window, for forward-facing visibility. The XVS will display fused images from an advanced computing system and cameras mounted on the upper and lower part of the aircraft’s nose.

The aft part of the aircraft will hold an F414 GE engine and other critical systems. Unlike typical aircraft, the engine inlet will be located on the upper surface of the X-59 and is one of many features that will help reduce the noise heard on the ground.

Over the next several months, the team will merge all three sections together. After final assembly in 2021, the X-59 will undergo numerous tests to ensure structural integrity of the aircraft and that ¬its components work properly. First flight of the aircraft will be in 2022 and community testing will start in 2024, making way for a new market of quiet commercial supersonic aircraft.

Vía Láctea desde Stintino, la cual es una localidad italiana de la provincia de Sassari en la región de Cerdeña.

El autor nos comenta que en uno de sus viajes visitando a un amigo, encontró esta granja de molinos de viento en la posición perfecta para hacer un arco de la Vía Láctea en ella.

La composición fue complicada porque por un lado quería hacer visibles los molinos de viento,

pero por otro lado para mostrarlos todos había que alejarse un poco de ellos. Por esta razón decidí usar la carretera principal como línea principal y poner a su amigo en el medio, usándolo como primer plano.

Asteroid Bennu, the Storyteller

Asteroids are the storytellers of our solar system’s youth. They are the closest we can get to the original material that makes up the sun, planets, and moons.

This week, our OSIRIS-REx spacecraft made history when it touched a pristine, ancient asteroid named Bennu to collect a sample from the surface. The intrepid spacecraft will now bring the asteroid sample – and its stories – back home to Earth.

Why is it that asteroid Bennu holds the history of our origins? Let’s go back to the beginning…

About 4.5 billion years ago, our solar system began as a spinning, swirling cloud made up of tiny bits of gaseous and rocky material. Most of that material – more than 99% of it – gathered in the center and went on to become the Sun.

The leftovers began to spin around the Sun, colliding into one another and forming larger and larger objects, eventually becoming planets, dwarf planets, and moons.

But asteroids didn’t become part of planets or moons. So, while the material in planets and moons were superheated and altered during the formation of the solar system and weathered by geologic processes over time, asteroids remained pristine.

Each asteroid holds knowledge from that special time in our solar system’s history. Each one contains information about the chemicals, minerals, and molecules that were present when the solar system was just starting to form.

With missions like OSIRIS-REx, we are going on a journey to these ancient worlds, seeking to learn what they remember, seeking to expand our knowledge, and deepen our understanding of our origins.
