Space News: La movilidad aérea avanzada hace que los viajes sean más accesibles

Image
https://ift.tt/avltwGg 4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) La Movilidad Aérea Avanzada conectará a los habitantes de las ciudades con los residentes de las zonas rurales ofreciendo una nueva forma de viajar en avión. Como se muestra en este arte conceptual, los pasajeros podrían viajar de las zonas rurales a la ciudad más rápidamente que en coche para subir a un avión comercial, recibir atención médica o comprar mercancías. NASA/Kyle Jenkins Read this feature in English here. Imagina pedir un taxi aéreo por app, como haces ahora con Uber o Lyft, para viajar a tu aeropuerto local: podrías elevarte por encima del tráfico de carretera y llegar mucho más rápido que si fueras en coche. Los creativos de la industria aeronáutica ya están diseñando servicios aéreos de viaje compartido entre casa y el aeropuerto. Las nuevas aeronaves autónomas y pilotadas por control remoto harán que los viajes aéreos sean más accesibles al pú...

Space News: New NASA Satellite To Unravel Mysteries About Clouds, Aerosols

Image
https://ift.tt/U1uocea 5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Some of the same properties of light and optics that make the sky blue and cause rainbows can also help scientists unlock mysteries about cloud formation and the effects of tiny particles in our air. NASA’s upcoming PACE mission will offer important insights on airborne particles of sea salt, smoke, human-made pollutants, and dust – collectively called aerosols – by observing how they interact with light. With PACE data, scientists will provide better answers to key questions such as how aerosols affect cloud formation or how ice clouds and liquid clouds differ. Understanding the nature of airborne particles and clouds is crucial to deciphering how climate and air quality are changing. Two instruments on NASA’s upcoming PACE mission will look at aerosols and clouds – the A and C in the name of the Plankton, Aerosol, Cloud, ocean Ecosystem satellite. After launch in early ...

Space News: NASA Selects 11 Space Biology Research Projects to Inform Biological Research During Future Lunar Exploration Missions

Image
https://ift.tt/075dkon 4 min read NASA Selects 11 Space Biology Research Projects to Inform Biological Research During Future Lunar Exploration Missions NASA announces the award of eleven grants or cooperative agreements for exciting new Space Biology research that will advance NASA’s understanding of how exposure to lunar dust/regolith impact both plant and animal systems. As human exploration prepares to go beyond Earth Orbit, Space Biology is advancing its research priorities towards work that will enable organisms to T hrive I n DE ep S pace (TIDES). The ultimate goal of the TIDES initiative is to enable long-duration space missions and improve life on Earth through innovative research. Space Biology supported research will enable the study of the effects of environmental stressors in spaceflight on model organisms, that will both inform future fundamental research, as well as provide valuable information that will better enable human exploration of deep space. ...

APOD: M15: Dense Globular Star Cluster

Image
Messier 15 is an immense swarm of over 100,000 stars. A 13 billion year old relic of the early formative years of our galaxy it's one of about 170 globular star clusters that still roam the halo of the Milky Way. Centered in this sharp reprocessed Hubble image, M15 lies some 35,000 light-years away toward the constellation Pegasus. Its diameter is about 200 light-years, but more than half its stars are packed into the central 10 light-years or so, making one of the densest concentrations of stars known. Hubble-based measurements of the increasing velocities of M15's central stars are evidence that a massive black hole resides at the center of the dense cluster. M15 is also known to harbour a planetary nebula. Called Pease 1 (aka PN Ps 1), it can be seen in this image as a small blue blob below and just right of center. via NASA https://ift.tt/aQoCO61

APOD: Encke and the Tadpoles

Image
History's second known periodic comet is Comet Encke (2P/Encke). As it swings through the inner Solar System, Encke's orbit takes it from an aphelion, its greatest distance from the Sun, inside the orbit of Jupiter to a perihelion just inside the orbit of Mercury. Returning to its perihelion every 3.3 years, Encke has the shortest period of the Solar System's major comets. Comet Encke is also associated with (at least) two annual meteor showers on planet Earth, the North and South Taurids. Both showers are active in late October and early November. Their two separate radiants lie near bright star Aldebaran in the head-strong constellation Taurus. A faint comet, Encke was captured in this telescopic field of view imaged on the morning of August 24. Then, Encke's pretty greenish coma was close on the sky to the young, embedded star cluster and light-years long, tadpole-shaped star-forming clouds in emission nebula IC 410. Now near bright star Spica in Virgo Comet Encke p...

APOD:

What causes this unusual curving structure near the center of our Galaxy? The long parallel rays slanting across the top of the featured radio image are known collectively as the Galactic Center Radio Arc and point out from the Galactic plane. The Radio Arc is connected to the Galactic Center by strange curving filaments known as the Arches. The bright radio structure at the bottom right surrounds a black hole at the Galactic Center and is known as Sagittarius A*. One origin hypothesis holds that the Radio Arc and the Arches have their geometry because they contain hot plasma flowing along lines of a constant magnetic field. Images from NASA's Chandra X-ray Observatory appear to show this plasma colliding with a nearby cloud of cold gas. via NASA https://ift.tt/R1WxbZ7
