El cohete de pruebas de vehículos de reentrada; el “Caballero Negro-The Black Knight” haría su primer vuelo desde el campo de pruebas Woomera en el sur de Australia, un sitio despejado para las pruebas de los misiles de los Británicos. En su primer vuelo el Caballero Negro-The Black Knight alcanzó una altura de 300 millas (482.8 Km.) y una distancia horizontal de 60 millas (965,61Km).
El primero de dos Caballeros Negros –The Black Knight era lanzado el 24 de mayo de 1960; llevando como segunda etapa un Cuckoo de propulsante sólido, un motor impulsor para el cohete de sondeo Skylark.
Mas tarde la propulsión de la primera etapa de cuatro cámaras mas poderosa era suministrada por el empuje de un motor Gamma 301 de 21000 lb. http://www.spaceuk.org/htp/htp.htm
Ocho vuelos fueron hechos con este motor. El Caballero Negro-The Black Knight de dos etapas podría levantar un vehículo de reentrada instrumentado de 250 lb. a una altura de 2000 millas (3218,62 Km.). Cuando llegaba a su altura máxima, una cabeza de 100 lb. sería expulsada a través de la atmósfera a una velocidad de 17000 pies / s (5,18 Km. / s) simulando la reentrada de una cabeza nuclear balística. El último de los 22 vuelos de los Caballeros Negros – The Black Knight tomaba lugar el 25 de noviembre de 1965, pero la tecnología sería aplicada al lanzador de satélites Black Narrow (Flecha Negra) el cual adoptaría una versión mejorada del motor Gamma

Free Spirit Exploring Options
John Callas, Project Manager, Mars Exploration Rovers: This is John Callas of the Jet Propulsion Laboratory with your Free Spirit Update.
Since we last updated you, we've begun the extraction testing here in our sandbox at JPL of our engineering rover in preparation for doing the actual driving on Mars with Spirit.
What the team is preparing to do right now is situate the rover for the next set of testing.
What we want to do is embed the rover.
So to do that, we are spinning each of the wheels individually.
You can see the left middle wheel spinning now.
That allows the wheel to sink in without moving the whole rover.
And so they'll do the five driving wheels to sink the rover down in,
just as Spirit is positioned on Mars, where all five of these driving wheels are embedded deeply in this soft, loose material.
We previously tested driving the rover forward, which we think is probably our most likely way of getting Spirit out.
But we want to look at all the options, so the next thing they'll do is driving the rover backwards to see if we can actually drive through this bad section on Mars. So they'll set it up here and then proceed to drive this rover backwards to see what kind of progress the rover makes and whether the rover has any problems like with sinkage because that's one of the things that could spell real trouble for Spirit on Mars.
Text: Meanwhile on Mars.
Although we've been busy moving this rover down here on Earth,
Spirit, up on Mars, hasn't moved in over two months.
But that doesn't mean the rover hasn't been busy.
When Spirit drove and got stuck in this particular location it churned up the soil and the science team are very interested in this particular soil.
They've been using all the instruments on the rover to investigate it.
This is John Callas of the Jet Propulsion Laboratory with your Free Spirit Update.

NASA Tests Alternate Launch Abort System For Astronaut Escape WALLOPS ISLAND, Va. -- NASA has successfully demonstrated an alternate system for future astronauts to escape their launch vehicle. A simulated launch of the Max Launch Abort System, or MLAS, took place Wednesday morning at 6:26 a.m. at NASA's Wallops Flight Facility, Wallops Island, Va.
The unpiloted launch tested an alternate concept for safely propelling a future spacecraft and its crew away from a problem on the launch pad or during ascent. The MLAS consists of four solid rocket abort motors inside a bullet-shaped composite fairing attached to a full-scale mockup of the crew module.
The 33-foot-high MLAS vehicle was launched to an altitude of approximately one mile to simulate an emergency on the launch pad. The flight demonstration began after the four solid rocket motors burned out. The crew module mockup separated from the launch vehicle at approximately seven seconds into the flight and parachuted into the Atlantic Ocean.
The test demonstrated a number of things: the unpowered flight of the MLAS along a stable trajectory; reorientation and stabilization of the MLAS; separation of the crew module simulator from the abort motors; and stabilization and parachute recovery of the crew module simulator. An important objective of the test was to provide the workforce of NASA's Engineering and Safety Center, or NESC, with experience in flight testing a spacecraft concept. NESC leads the project at NASA's Langley Research Center in Hampton, Va.
NASA has chosen another launch abort system, known as the LAS, for the Orion spacecraft. The system has a single solid launch abort motor in a tower mounted at the top of the launch vehicle stack of the Orion and Ares I rocket. The LAS will be capable of automatically separating the spacecraft from the rocket at a moment's notice to make possible a safe landing. Orion, part of a new spacecraft system NASA's Constellation Program is developing, is undergoing design reviews in preparation for flying astronauts to the International Space Station in 2015 and, later, to the moon.
Data from today's MLAS pad abort test could help NASA in several ways. MLAS is the first demonstration of a passively-stabilized launch abort system on a vehicle in this size and weight class. It is the first attempt to acquire full-scale aero-acoustic data -- the measurement of high loads on a vehicle moving through the atmosphere at high velocity -- from a faired capsule in flight. The test is also the first to demonstrate full scale fairing and crew module separation and collect associated aerodynamic and orientation data. In addition, data from the parachute element will help validate simulation tools and techniques for Orion's parachute system development.
The NESC is an independently funded NASA program that draws on technical experts from across all NASA centers to provide objective engineering and safety assessments of critical, high risk projects.
The MLAS is named after Maxime (Max) Faget, a Mercury-era pioneer. Faget was the designer of the Project Mercury capsule and holder of the patent for the "Aerial Capsule Emergency Separation Device," which is commonly known as the escape tower.
NESC partners in the MLAS effort include Northrop Grumman Corporation.

El Planetario de Medellín conmemorando los cuarenta años de la llegada del hombre a la luna se complace en invitar a la conferencia “Regreso a la luna: el viaje ha comenzado” del profesor Cesar Ocampo de la Universidad de Texas.
Resumen
Esta presentación está orientada a una audiencia general interesada en temas espaciales. El enfoque será el regreso a la luna vía misiones robóticas y misiones tripuladas. Se presentarán temas relacionados con la historia de la luna, mecánica celeste, la historia de las misiones Apollo y sus precursoras. Se revisará adicionalmente el proyecto Constellatoin/Orion que nos llevará de nuevo a la luna en el futuro.
Esta imagen compuesta muestra la accidentada región polar sur y es el mapa topográfico de más alta resolución hasta la fecha del polo sur de la Luna. Fué generado por científicos del Laboratorio de Propulsión a Chorro de la NASA(NASA's Jet Propulsion Laboratory), utilizando los datos recolectados a través del Radar del Sistema Solar Goldstone de la Red de Espacio Profundo (the Deep Space Network's Goldstone Solar System Radar) situado en el desierto de Mojave en California. Este nuevo mapa proporciona detalles topográficos sobre una región de aproximadamente 311 millas por 249 millas (500 kilómetros por 400 kilómetros).
Como Saturno ha avanzado en su órbita hacia equinoccio y el sol poco a poco se ha movido hacia el norte del planeta, el movimiento de las sombras del anillo de Saturno y los colores cambiantes de su atmósfera continuaron para transformar la cara de Saturno visto por Cassini en esta imagen del cuarto año de la misión .
Cassini ha estado orbitando Saturno durante cinco años Terrestres desde el 30 de junio de 2009. Esto es aproximadamente una sexta parte de un año Saturniano, tiempo suficiente para que la nave espacial haya observado los cambios estacionales en el planeta, sus lunas y del ángulo de la luz solar sobre los dramáticos anillos.
Este cautivadora imagen de color natural, fue creada a partir de imágenes recogidas poco después que comenzó su Misión Equinoxio en julio de 2008. El mosaico combina 30 imágenes - 10 de cada una en luz roja, verde y azul a lo largo del curso de aproximadamente dos horas tan pronto el Cassini desplegó su cámara de campo amplio a través de todo el planeta y el sistema de anillos el 23 de julio de 2008, desde una elevación hacia el sur de 6 grados.
Seis lunas completan esta imagen (véase la imagen en tamaño completo): Titan (3200 millas o 5150 kilómetros, de distancia), Janus (111 millas o 179 kilómetros, de distancia), Mimas (396 kilómetros o 246 millas, de distancia) Pandora (81 kilómetros o 50 millas, de distancia), Epimetheus (70 millas o 113 kilómetros, de distancia) y Enceladus (504 kilómetros o 313 millas, de distancia).
Cassini capturó estas imágenes a una distancia de aproximadamente 690000 millas (1.1 millones de kilómetros) de Saturno y con un ángulo o fase entre el Sol-Saturno y la Nave Espacial de 20 grados.
The moon, our nearest celestial neighbor, has intrigued and inspired us since the dawn of humanity.
During the Apollo Program, 12 astronauts landed on its cold and cratered surface. But they couldn't stay.
Now, NASA's Constellation Program begins a new journey: to live and work on the moon, setting the stage for future, long-duration human exploration.
Today, two spacecraft scouts are poised to lift off together aboard a powerful Atlas V rocket on the first launch of this new era.
They are the Lunar Reconnaissance Orbiter and the Lunar Crater Observation and Sensing Satellite, or LRO and LCROSS.
One rocket. One destination. Two critical missions.
Together, they're helping us pave the way back to the moon.

Welcome to the show. I'm your host, George Diller.
I'm here at NASA's Kennedy Space Center in Florida, inside the Apollo Saturn V Center. Behind me is an actual, massive, 363-foot-long Saturn V rocket just like those that boosted the Apollo astronauts on America's first human missions to the moon.
Today, NASA is preparing to return to the moon, beginning with the Lunar Reconnaissance Orbiter and the Lunar Crater Observation and Sensing Satellite. This upcoming launch aboard an Atlas V rocket is the critical first step in the new Constellation Program.
On today's show, we're going to take you inside both of these exciting missions, and find out what it takes to launch two spacecraft at once.
Our first guest is Cathy Peddie, deputy project manager for the Lunar Reconnaissance Orbiter. She stopped by the NASA Direct studio to give us the inside story on this moon-mapping mission.
Cathy Peddie/LRO Deputy Project Manager: The Lunar Reconnaissance Orbiter project, or LRO's main goal, is we're really the first mission, the first step that NASA is taking back to exploring our universe. And so what we really need to do is have a reconnaissance mission, you know, get more data. Now one of the things that we want to do is go back to the moon.
You know, we've been there before. We have really awesome data sets from our previous missions, from the Apollo era to the other spacecraft that have gone. So we want to build upon those data sets that we already have. And most of those data sets really focused on the equatorial region of the moon. So now we want to go back and say, 'Hey, let's map the entire moon.' So have more of a global perspective, or a comprehensive atlas of the moon. And help whoever wants to join us in exploring our universe, or taking that next step back they need to have a more comprehensive atlas of the moon so that they know where to go, what to do, what to expect, that kind of thing. Help them out. We're like a scout mission for the exploration.
Roughly a couple days after we launch, we will begin what we call the lunar orbit insertion burn. And that burn will help us, or help the moon and us, get captured by the moon. And so, what happens during that burn is LRO starts to get closer to the moon and the moon will capture LRO. And once we have that confirmation that the moon has captured us, we call that lunar acquisition. And after we have lunar acquisition for, and we’re sure that we have a stable orbit, then we will begin a series of burns that are roughly a day apart from each other. A series of four or five burns that begin to lower LRO into her final orbit, which is roughly 50 kilometers above the moon, or 31 miles. And that's LRO's polar orbiting orbit where we lower the spacecraft low enough so that the instruments can focus on the surface of the moon and begin the data collection that is what our mission is all about to create that comprehensive atlas of the moon.
Now, an interesting offshoot to our data is that our data will also be made available to Google Moon so that anyone that has access to the Web or Google will be able to punch in, I don’t know, like Shackleton crater, and be able to see all the cool data from LRO pop up right on their own personal computers at home.
At NASA we're all about exploring and pushing our knowledge across the boundaries. And LRO, even though taking us back to the moon where we've been before there's a lot about our moon that we don’t know, and a lot about our moon that we want to use as we begin to look out into the universe and decide, you know, where we want to go next. So having a reconnaissance, or a scout mission, that begins to take us out is a perfect fit into what NASA's all about. And what people like me, who've dreamed about working for NASA have always wanted to do. You know, explore, look out beyond who and what we are today. And LRO is the perfect fit for that type of vision for all of us.
George Diller/NASA Public Affairs Officer: Now that we know what to expect from the Lunar Reconnaissance Orbiter, we turn our attention to its sister payload the Lunar Crater Observation and Sensing Satellite. Its goal is to hunt for evidence of water ice using a hard-hitting method. Dr. Kimberly Ennico, LCROSS payload specialist, explains.
Dr. Kimberly Ennico/LCROSS Payload Specialist: LCROSS mission has two impact events. The first is the upper stage of the launch vehicle that we take with us on our four-month mission into space. And we separate from it, and its traveling to hit the moon at 5,600 mph.It's going to impact one of these lunar, permanently-shadowed basins of a crater on the lunar poles. And it's going to hit a particular place. It's going to hit a place on the moon where we think there's water. Scientists who believe that there is water on the moon don't know if it's smooth or chunky-peanut butter type. So where you hit is important. The secondary impact is the LCROSS payload, which will impact somewhere between 3 to 5 kilometers away from the first impact. So we're going to hit another part of that crater. We've targeted this crater because it's got a strong hydrogen concentration. We're going to sample two parts of this crater. And so the two impact events will tell us something about the distribution of this hydrogen concentration or perhaps the distribution of water, if the hydrogen is in water.
The live images of our, what we're taking with our science payload as we're going into the surface during the last four minutes of the mission, which is 600 kilometers down to the surface, will be streamed live on a public channel.
LCROSS is important because it provides us a way to confirm the presence or absence of water ice at a particular location on the lunar pole. If there's water ice there, or water in some form, it means that for future missions to the moon and perhaps beyond, there's an in situ, a resource that's there. Resources on the surface of that planet, you don't need to bring it with you. So for the human species, in terms of exploring the rest of the solar system, so getting out of low Earth orbit and we need water with us if we can find a resource of water on the moon, that will be an amazing step forward and a great resource to take advantage of in a very resource-limited place.
George Diller/NASA Public Affairs Officer: Both LRO and LCROSS need a successful launch in order to begin their missions. Our next guest is an integral part in getting these spacecraft and many others off the ground. Chuck Tatro is a mission manager in NASA's Launch Services Program at Kennedy Space Center. He's going to tell us about the unique challenges of this two-for-one launch.
Chuck Tatro/Launch Services Program Mission Manager: Hello, my name is Chuck Tatro and I'm a mission manager for NASA's Launch Services Program at Kennedy Space Center.
We're at the Vertical Integration Facility on Cape Canaveral Air Force Station. This is where we will assemble the Atlas V rocket that will send the LRO and LCROSS spacecraft on their journey to the moon.
As a mission manager, my job is to lead the effort to bring a new spacecraft and launch vehicle together to where they're ready to launch. About three months before launch, the spacecraft and launch vehicle components arrive at the launch site for final testing. About two months before launch, the rocket components are erected on the launch platform and filled with cryogenic fluids for a wet dress rehearsal. About two weeks before launch, the spacecraft is brought out here to the Vertical Integration Facility and stacked on the rocket. At about one week before launch we do a launch countdown rehearsal, so the team can practice for countdown.
In a dual payload flow, both spacecraft have their own intricate and intimate requirements that are separate, and may not play together nicely with the other spacecraft. For example, contamination, orbital requirements. Because LCROSS is going to impact the moon and LRO is going to go in orbit around the moon, we need to make sure that one doesn't adversely impact the other.
The first challenge on this mission is the fact that the Centaur second stage will remain attached to the LCROSS spacecraft after it does its normal job of delivering LRO and LCROSS on their journey to the moon. LCROSS then will command the Centaur stage for an impact into the lunar surface. The second challenge is that the orbit requirements for each spacecraft are complex. This narrows the daily launch window that we have to launch this mission. The third challenge is that this is NASA's first step in our return to the moon, so there's a lot of public awareness and increased interest in this mission. We want to make sure that this mission is launched safely and successfully.
George Diller/NASA Public Affairs Officer: That's our show. To our guests Cathy Peddie, Kim Ennico and Chuck Tatro thanks for giving us an insider's view of these two missions.
We also thank all of you for joining us for today's webcast.
Be sure to join us on launch day for the liftoff of the Atlas V rocket carrying the Lunar Reconnaissance Orbiter and the Lunar Crater Observation and Sensing Satellite. You can follow the countdown on NASA TV and on each mission's Web site, at www.nasa.gov/lro and www.nasa.gov/lcross.

El aparato de mas 20000 libras (9072 kg), llamado el Equipo de Prueba del Sistemas de Atenuación de Impacto de la Tripulación-(Crew Impact Attenuation System Test Article), representan los asientos del módulo de la tripulación del Orión que acomodará de 4 a 6 astronautas.
El equipo de prueba se dejó caer desde una altura de 18-pies (5,5 m) dentro de un material en forma de nido de abeja aplastable , el cual está escala para representar las diversas condiciones de aterrizaje que el Orion podría enfrentar. Las riostras de absorción de energía reducirán las cargas percibidas por la tripulación durante el aterrizaje.
El Planetario de Medellín se complace en invitarlos a la conferencia "Inteligencia artificial en el mundo real" , a ser ofrecido por el Ingeniero y candidato a MSc. Juan Sebastian Botero, miembro del centro de investigaciones del ITM
Resumen
La Inteligencia Artificial (IA) es una rama de las ciencias de la información que busca el desarrollo de agentes inteligentes para intervenir un proceso y maximizar una medida de rendimiento; La ciencia ficción a profundizado en la distorsión de esta realidad práctica, y es necesario llevar al público una nueva visión en la que la IA aparece para mejorar nuestra calidad de vida. En la conferencia se trataran las bases de la IA, su vinculación a la cotidianidad, el impacto en los sistemas de producción y la relación con los fundamentos de inteligencia Humana.
