La NASA enviará una nave espacial muy cerca del Sol
Aunque cada vez son más sorprendentes las imágenes que obtenemos del astro gracias a la precisión de los nuevos telescopios, la NASA quiere ir más allá, y planea enviar una nave espacial no tripulada a la atmósfera exterior de la estrella
Según informa la BBC, el lanzamiento de la nave Solar Probe Plus (SPP) tendría lugar antes de 2018. Es un reto jamás llevado a cabo, nunca una nave se había acercado tanto a la estrella.
Según el proyecto, la nave sería capaz de obtener valiosos datos acerca del Sol antes de morir ‘frita’ a temperaturas superiores a los 1.400 ºC.

Para poder soportar las altas temperaturas y radiaciones el instrumental estará protegido con un enorme escudo térmico. Su misión será captar información sobre la atmósfera exterior del Sol, también llamada corona solar, que desconcierta a los científicos por tener una temperatura mucho mayor a la de la superficie del astro.
Por primera vez vamos a ser capaces de tocar, saborear y oler nuestro Sol
“Por primera vez vamos a ser capaces de tocar, saborear y oler nuestro Sol”, ha declarado a la BBC Lika Guhathakurta, científico del programa SPP de la NASA.
La nave estará equipada con un avanzado instrumental, como un detector de partículas de viento solar, una cámara 3D y dispositivos para medir el campo magnético.
La NASA califica en la página web del proyecto de “extraordinaria e histórica” esta misión de exploración de la última región del sistema solar que queda por recibir la visita de una nave espacial.

Closest-Ever Probe of Sun is New NASA Mission
Solar Probe Plus, a new NASA mission to visit and study the sun closer than ever before, is officially underway. The spacecraft will plunge directly into the sun’s atmosphere at approximately 4 million miles from the surface into a region no
other spacecraft has ever encountered.
HubbleART: Pearl Jam to Final Doom
The latest gem from ESA’s HubbleCast in 1080P. The Hubble Space Telescope has inspired widespread awe in the beauty and complexity of the Universe. But with its stunning gallery of images, Hubble has also become embedded in popular culture.

What’s Up in September 2010
Rocket Motor Fired in Utah Test Stand
NASA’s next-generation, five-segment solid rocket development motor — or DM-2 — was successfully fired in its test stand at ATK in Promontory, Utah. Prior to the firing, which lasted just more than two minutes, the motor’s overall temperature was lowered to 40 degrees Fahrenheit to validate the motor’s ability to perform properly in cold weather.
Station Cameras Provide New View of Hurricane Earl
Cameras mounted on the International Space Station captured new views of Hurricane Earl late in the afternoon of Sept. 2 from an altitude of 218 statute miles as the storm churned due east of South Carolina heading north on a track that would skirt the eastern seaboard of the United States. Earl was packing winds of about 115 miles an hour at the time the video was acquired.
Three Rotations in Three Temperatures
Solar images in three different wavelengths in extreme ultraviolet light are combined together to show solar activity over almost three months (June 2 — Aug. 26, 2010). Each wavelength is shown in a different color. The wavelengths are at 211 (red – 2 million degrees), 193 (green – 1.3 million degrees), and 171 Angstroms (blue – 600,000 degrees). The cadence is basically a frame every 45 minutes. The brightest areas are active regions, which have stronger magnetic field than the surrounding area.
