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.

El Observatorio Abbey Ridge de Dave Lane tomó este video del asteroide (99942) Apophis mientras "pasaba zumbando" por la Tierra.
Aunque la aparición de 2021 no está muy cerca de la Tierra (Aprox. a 44 distancias lunares), el Asteoide Apophis es de particular interés porque en 2029 se acercará a unos ~40.000 km.
Las exposiciones fueron de 20 segundos durante aproximadamente 30 minutos. El asteroide es la "estrella" en movimiento cerca del centro del video.

El 22 de Febrero se publicó esta imagen por la Agencia de Exploración Aeroespacial de Japón (JAXA) donde se muestra la sombra en el centro, de la nave espacial Hayabusa2 después de su aterrizaje exitoso en el asteroide Ryugu. La nave espacial japonesa se está acercando a la Tierra después de un viaje de un año a casa desde un asteroide distante que lleva muestras de suelo y datos que podrían proporcionar pistas sobre los orígenes del sistema solar, dijo un funcionario de la agencia espacial el viernes 27 de noviembre de 2020.

For the first time, astronomers may have detected an exoplanet candidate outside of the Milky Way galaxy. Exoplanets are defined as planets outside of our Solar System. All other known exoplanets and exoplanet candidates have been found in the Milky Way, almost all of them less than about 3,000 light-years from Earth.
This new result is based on transits, events in which the passage of a planet in front of a star blocks some of the star's light and produces a characteristic dip. Researchers used our Chandra X-ray Observatory to search for dips in the brightness of X-rays received from X-ray bright binaries in the spiral galaxy Messier 51, also called the Whirlpool Galaxy (pictured here). These luminous systems typically contain a neutron star or black hole pulling in gas from a closely orbiting companion star. They estimate the exoplanet candidate would be roughly the size of Saturn, and orbit the neutron star or black hole at about twice the distance of Saturn from the Sun.
This composite image of the Whirlpool Galaxy was made with X-ray data from Chandra and optical light from our Hubble Space Telescope.

"La Vía Láctea se precipitó en diagonal a través de los cielos, recordándome mi absoluta insignificancia, y al mismo tiempo mi completa interconexión con todo. Yo era solo una pequeña partícula de conciencia, y sin embargo yo era la conciencia misma", comentarios del autor.
