Espacio NEGOCIO : Construyendo un camión de basura para el espacio

http://www.cromo.com.uy/construyendo-un-camion-basura-el-espacio-n1014779
http://www.cromo.com.uy/japon-lanza-un-recolector-basura-espacial-n1008622



Martin Fackler / New York Times News Service

Mitsunobu Okada aspira a ser más que un recolector de basura común: quiere crear la primera empresa de recolección de basura espacial (a la que llamó Space Sweepers -Barrenderos espaciales-) dedicada a recoger las etapas de cohetes desechadas, los satélites inertes y otros escombros acumulados sobre la Tierra.

La empresa Astroscale nació hace tres años porque Okada creía que el problema podía ser abordado más rápidamente por una compañía privada motivada por las utilidades.

En el último medio siglo, la órbita terrestre baja se llenó de tantos escombros que existe un creciente peligro de colisiones con satélites y las naves espaciales tripuladas.

La Fuerza Aérea de Estados Unidos sigue unas 23,000 piezas de basura espacial lo suficientemente grandes para ser detectarse desde la Tierra. Los científicos dicen que puede haber decenas de millones de partículas más pequeñas que no pueden distinguirse, que se mueven a velocidades lo suficientemente rápidas para que se conviertan en proyectiles.

Cada vez más poblada

En los últimos años se han ideado planes para hacer a la órbita baja aún más concurrida, y más esencial para las comunicaciones en la Tierra, con la creación de enormes redes nuevas de miles de satélites para ofrecer globalmente conectividad de internet y cobertura de telefonía celular.

El crecimiento del tráfico incrementa el riesgo de colisiones que pudieran alterar las comunicaciones, y cada choque crea una nube de esquirlas desencadenando potencialmente una reacción en cadena de colisiones que pueden volver inutilizable la órbita baja. Aquí es donde entra Okada, quien dijo que creó un plan de dos pasos para ganar dinero con la remoción de escombros.

Primero, Astroscale planea lanzar un satélite de 23 kilos el año próximo a bordo de un cohete ruso que compilará los primeros mapas detallados de la densidad de los escombros, los cuales pueden ser entonces vendidos a los operadores de satélites y las agencias espaciales. Añadió que ya ha recaudado US$ 43 millones de inversionistas.

El paso más ambicioso tendrá lugar en 2018, cuando Astroscale lance una nave que rastreará e interceptará los desechos. Esta compañía ha trabajado con una empresa química japonesa para crear un adhesivo que cubra una superficie plana del tamaño de un plato extendido. La nave se toparía con una pieza de basura espacial, que se pegaría a la nave y sería retirada de la órbita. Tanto la nave como los escombros se quemarían al reingresar a la atmósfera.

La clave para reducir un precio de decenas, o incluso cientos de millones de dólares, es reducir el peso. Dijo que el adhesivo pesaría mucho menos que un brazo robótico de 45 kilos, y que los ingenieros de su compañía habían encontrado formas de reducir el peso de la nave a 91 kilos, haciéndola mucho más ligera que otras naves propuestas.

"En Estados Unidos, los ingenieros aeroespaciales están más interesados en trabajar en misiones a Marte, no en gestión de desechos", dijo Okada. "Japón no tiene tantas misiones espaciales interesantes, así que los ingenieros se entusiasmaron con mi idea".



Japón lanza un recolector de basura espacial

Es una soga que desplaza restos de cohetes para que se desintegren en la atmósfera Tierra



Japón envió este viernes al espacio una nave con suministros con destino a la Estación Espacial Internacional (ISS) que también incorpora un nuevo sistema para deshacerse de la basura espacial.
La nave, llamada "Kounotori 6" ("Cigueña 6"), fue lanzada desde la isla de Tanegashima pocos segundos antes de las 22:27 locales por el cohete H-IIB, según imágenes difundidas en director por la agencia espacial japonesa Jaxa.
El lanzamiento fue un éxito y "el satélite se separó del cohete" y se puso en la órbita prevista, dijo a la AFP un portavoz de Jaxa, Nobuyoshi Fujimoto quince minutos después del despegue.
La nave lleva una especie de soga que desplaza la basura espacial creada por el hombre, como restos de satélites o de cohetes, y la lleva hacía órbitas cercanas a la Tierra con el objetivo de que acaben entrando en su atmósfera y desitengrándose.
Desde el lanzamiento en 1957 del satélite soviético Sputnik, la exploración humana del espacio ha dejado un rastro de deshechos que cada año provocan choques con naves espaciales.
El cable, llamado electrodinámico, está hecho con filamentos de acero y de aluminio y fue diseñado con la ayuda de un fabricante de redes de pesca.
Cuando se balancea en el campo magnético terrestre, el cable genera electricidad y frena el movimiento de los deshechos, que luego empezarán a bajar progresivamente hasta entrar en la atmósfera y quemarse sin llegar a la superficie de la Tierra, según las previsiones de los científicos.
La agencia espacial japonesa ha trabajado diez años con la empresa Nitto Seimo para desarrollar este sistema.
"La soga utiliza nuestra técnica de trenzado de redes pero fue muy difícil entrelazar elementos tan delgados", explicó a la AFP Katsuya Suzuki, un ingeniero de la compañía.
"Esta vez la soga tendrá 700 metros de longitud pero al final tendrá que llegara a los 5.000 o 10.000 metros de largo para frenar la basura espacial que queremos destruir", añadió.
La "Kounotori 6" también transporta víveres, pilas y agua para los astronautas de la ISS.

Five weeks after delivering approximately five tons of supplies and experiments to the International Space Station, an unpiloted Japanese cargo ship is scheduled to depart the station Monday, Sept. 28. NASA Television will provide live coverage of the departure beginning at 11 a.m. EDT.

Robotic flight controllers in the Mission Control Center at NASA’s Johnson Space Center in Houston will begin preparing the Japan Aerospace Exploration Agency’s (JAXA) H-II Transport Vehicle-5 (HTV-5) for unberthing from its port on the station’s Harmony module several hours before its release.

Expedition 45 Flight Engineer Kimiya Yui of JAXA, backed up by NASA Flight Engineer Kjell Lindgren, will command the station’s Canadarm2 robotic arm to release HTV-5, loaded with station trash at about 11:20 a.m. A few hours after its release, the cargo ship will fire its engines to begin a controlled deorbit and entry through Earth’s atmosphere, where it will burn up over the Pacific Ocean.

HTV-5 carried a variety of experiments and supplies to the space station, including the NanoRacks External Payload Platform, which can house multiple investigations in the open-space environment of the station, and the CALorimetric Electron Telescope investigation, an astrophysics mission that measures high energy particles to search for dark matter and the origin of cosmic rays.

Also aboard were various nanosatellites used for space research, known as CubeSats, including 14 Planet Labs Dove satellites, which will capture images of Earth for use in humanitarian, environmental and commercial applications. GomSpace GOMX-3 is a small satellite containing three radios. One radio receives beacons from commercial aircraft to improve air traffic monitoring, while the other two test reception and data downlink in the L-band, used by GPS satellites, and the X-band, used by the military and for weather monitoring, air traffic control and other uses.

HTV-5 also delivered materials to support the Twins Study, a compilation of 10 investigations designed to gain broader insights into the subtle effects of and changes that occur in the environment of space as compared to that of Earth by studying two individuals who have the same genetics, but are in different environments. NASA astronaut Scott Kelly is participating from the space station while his identical twin Mark Kelly, a retired astronaut, is participating on Earth. The study includes a suite of integrated human space physiology and cellular-level experiments.

NASA : Hinode Captures Images of Partial Solar Eclipse

Hola amigos: A VUELO DE UN QUINDE EL BLOG., la Agencia Espacial NASA, nos informa sobre una vista captada por The Hinode spacecraft, de un eclipse parcial del Sol--- ....... "Un eclipse solar parcial fue visible desde gran parte de América del Norte antes de la puesta del sol el jueves, Oct.23. Un eclipse parcial ocurre cuando la Luna bloquea una porción del sol a la vista..............La nave espacial Hinode capturó imágenes de Eclipse de ayer, ya que pasó por encima de América del Norte usando su telescopio de rayos X. Durante el eclipse, la luna nueva alivió a través del sol de derecha a izquierda con el Sol brillando brillantemente en el fondo. Y como un golpe de buena suerte, región activa más grande de este ciclo solar, que ha sido la fuente de varios grandes llamaradas durante la semana pasada, tuvo su epicentro en el disco del sol como la luna transitó!.......
 
Hinode está en el octavo año de su misión para observar el sol. Anteriormente, Hinode ha observado numerosos eclipses debido a su gran altitud, órbita sincronizada con el sol. Visto desde el punto de vista de Hinode en el espacio, este eclipse fue anular en vez de parcial, lo que significa que toda la luna se puso delante del sol, pero no lo cubre completamente. En esta situación, un anillo del sol rodea el disco oscuro de la luna................"
 
Hinode Captures Images of Partial Solar Eclipse
A partial solar eclipse was visible from much of North America before sundown on Thursday, Oct.23. A partial eclipse occurs when the moon blocks a portion of the sun from view.
The Hinode spacecraft captured images of yesterday’s eclipse as it passed over North America using its X-ray Telescope.  During the eclipse, the new moon eased across the sun from right to left with the Sun shining brilliantly in the background.  And as a stroke of good luck, this solar cycle’s largest active region, which has been the source of several large flares over the past week, was centered on the sun’s disk as the moon transited!
Hinode is in the eighth year of its mission to observe the sun. Previously, Hinode has observed numerous eclipses due to its high-altitude, sun-synchronous orbit.  As viewed from Hinode’s vantage point in space, this eclipse was annular instead of partial, which means that the entire moon moved in front of the sun but did not cover it completely.  In this situation, a ring of the sun encircles the dark disk of the moon.
Led by the Japan Aerospace Exploration Agency (JAXA), the Hinode mission is a collaboration between the space agencies of Japan, the United States, the United Kingdom and Europe. NASA helped in the development, funding and assembly of the spacecraft's three science instruments.
Hinode is part of the Solar Terrestrial Probes (STP) Program within the Heliophysics Division of NASA's Science Mission Directorate in Washington. NASA's Marshall Space Flight Center in Huntsville, Ala., manages the Hinode science operations. The Smithsonian Astrophysical Observatory is the lead U.S. investigator for the X-ray telescope.

Developing and Testing Planetary Sample Collection Techniques

The Importance of Planetary Sample Returns

Dr. Mary Sue Bell of NASA's Astromaterials Research and Exploration Science Directorate explains why it's important to help astronauts develop sample collection techniques during NASA's analog missions.
 

Why are planetary sample returns so important?

Planetary science has seen a tremendous growth in new knowledge as a result of recent NASA robotic missions that have detected deposits of water-ice at the moon's poles and potential conditions under which life could have flourished on Mars.

While some sophisticated data can be derived from "in situ" measurements taken by rovers and satellites, returned planetary samples allow scientists on Earth to use latest technologies available to maximize the scientific return. The science community has recently seen compelling sample returns, including solar wind particles (NASA's Genesis), comet particles (NASA's Stardust) asteroid particles (JAXA's Hayabusa) and Antarctic meteorites, which scientists collect each Austral summer.

The National Research Council Decadal Study of 2011 recommended that NASA's chief scientific goal should be to return samples from Mars by 2023. Measurements taken by the MER rovers Spirit and Opportunity indicate that Mars had a warmer and wetter climate early in Mars history – conditions in which scientists believe life could have formed on early Mars. But chemical evidence of life in materials like the rocky regolith of Mars can be quite small and difficult for robotic geologists to detect and measure.
 
The Astromaterials Research and Exploration Science (ARES) directorate at NASA's Johnson Space Center curates all of NASA's "extraterrestrial" samples. The ARES directorate mission is to protect, preserve, and distribute samples for study from the Moon, Mars, and interplanetary space in support of solar system exploration. These sample collections include lunar rocks and regolith returned by the Apollo missions.

Samples from Mars will require special handling protocols from the time the sample collection site is chosen through documentation, encapsulation, and transport to Earth and to NASA's curation facility for allocation to scientist for analysis and study. Because scientists don't yet know how to differentiate an Earth-derived sample of life from a Mars-derived sample of life, scientists are eager to develop protocols that will protect Mars samples from Earth contamination. Landers, collection tools and sample containers could all carry trace amounts of Earthly biology, so must be equipped with decontamination materials and procedures to protect the precious samples.

How do NASA's analog missions, like NEEMO, help scientists develop special sample handling techniques for their exploration programs?

Planetary environments are considered extreme for both robotic and human exploration. Apollo astronauts experienced lower gravity on the moon than on Earth and a very thin atmosphere that required them to wear a space suit with life protection and support systems. When they collected moon rocks, the astronauts didn't know if they were exposing themselves to health hazards, so they wore large bulky gloves and used special sample collection tools and containers. These protective materials and special sample devices were developed in laboratories at Johnson Space Center and then tested in the field by geologists. After the sampling tools and techniques were sufficiently refined, Apollo astronauts were trained to use the techniques developed by the scientists.
 
Today, ARES scientists are developing tools and techniques for use on planetary surfaces with the same life support requirements and gravity conditions for human exploration as on the moon or Mars but lower gravity environments like near-Earth asteroids as well. Low gravity environments present special obstacles for collecting and containing geologic materials because loose material can drift away and an astronaut can be propelled away from a planetary surface just by hitting a rock with a hammer. NASA's Extreme Environment Mission Operations (NEEMO) is an undersea research facility that allows humans to experience reduced gravity due to the buoyancy provided by water in an environment requiring life support for breathing air. During NEEMO 16, NASA can refine sample collection techniques in an extreme environment and train astronauts to use tools and procedures developed for those unique conditions.

NASA develops tools and techniques during analog missions to ensure the scientific integrity of samples returned from a variety of planetary surfaces both by robots and by human explorers. NASA's returned samples will help scientists understand the formation and evolution of the solar system and determine if life or the conditions for life existed on other plantary bodies. These returned samples will be curated for future generations and allow them to employ advanced techniques not yet available to scientific researchers.

How does this Analog activity fit with NASA's current mission plans?

NASA is actively planning to expand the horizons of human space exploration, and with the Space Launch System and the Orion crew vehicle, humans will soon have the ability to travel beyond low Earth orbit. That opens up a solar system of possibilities, and NASA's goal is to send humans to explore an asteroid by 2025. Other destinations may include the moon or Mars and its moons.

Regardless of the destination, the work must start now. NASA is developing the technologies and systems to transport explorers to multiple destinations, each with its own unique – and extreme – space environment. Because sample return requirements are mission specific, the handling protocols are designed specifically for the types of questions the scientific community hopes to answer using samples from a particular planetary destination. ARES curation scientists are in collaboration with the mission architecture engineers to develop mission goals that are aligned with the science goals. ARES scientist participate in analog missions for protocol development and science operations development from mission conception to execution and sample return to ensure that the requirements of the scientific community will be met and the scientific return to the public will be maximized.

NASA : Global Precipitation Measurement Core Observatory Aboard H-IIA Rocket


Global Precipitation Measurement Core Observatory Aboard H-IIA Rocket
A Japanese H-IIA rocket carrying the NASA-Japan Aerospace Exploration Agency (JAXA) Global Precipitation Measurement (GPM) Core Observatory rolls out to launch pad 1 at the Tanegashima Space Center, Thursday, Feb. 27, 2014, Tanegashima, Japan. Once launched, the GPM spacecraft will collect information that unifies data from an international network of existing and future satellites to map global rainfall and snowfall every three hours.
The rocket is scheduled to lift off during a launch window that opens at 1:37 p.m. EST on Thursday, Feb. 27 (3:37 a.m., Friday, Feb. 28 Japan time).
GPM is an international satellite mission to provide next-generation observations of rain and snow worldwide every three hours. The GPM Core Observatory satellite carries advanced instruments that will set a new standard for precipitation measurements from space. The data they provide will be used to unify precipitation measurements made by an international network of partner satellites to quantify when, where, and how much it rains or snows around the world.
The GPM mission will help advance our understanding of Earth's water and energy cycles, improve the forecasting of extreme events that cause natural disasters, and extend current capabilities of using satellite precipitation information to directly benefit society.
