By Maggie McKee. news (June 27, 2005). "A voice-operated computer assistant is set to be used in space for the first time on Monday its operators hope it proves more reliable than 'HAL', the treacherous speaking computer in the movie 2001. Called Clarissa, the program will initially talk astronauts on the International Space Station through tests of onboard water supplies. But its developers hope it will eventually be used for all computer-related work on the station. ... Clarissa queries astronauts about the details of what they need to accomplish in a particular procedure, then reads through step-by-step instructions. Astronauts control the program using simple commands like 'next' or more complicated phrases, such as 'set challenge verify mode on steps three through fourteen'."

Space Systems
Trends, Threats and Opportunities
It is expected that advances in technologies such as microstructural materials and nanotechnologies, will lead to new components for space that will have a higher performance to cost ratio. For example, the use of these components could improve the sensitivity of sensors, improve the efficiency of power systems or reduce the weight of space structures. Use of these components, such as Transmit Receive (T/R) modules, in Space Systems should reduce the cost of many space missions or may lead to new capabilities in ISR. It is also expected that improvements in algorithms and processing of space data will lead to better exploitation of the resource and new applications. Since it is unlikely that Canada will develop an independent military space capability, our space technology investment strategy will feature collaboration with the Canadian Space Agency and with allies such as the United States and the United Kingdom.
Strategic Objectives
(A) Development of processing and exploitation techniques and applications for space-derived intelligence, surveillance and reconnaissance data: Develop new processing and exploitation tools to assist in obtaining relevant information from space-based sources, and develop applications for this information.

An artist’s impression of a Mars rover – one of the spacecraft that the Parkes telescope will be tracking (NASA) As numerous spacecraft converge on Mars over the coming months to search for signs of life, the Australian telescope which relayed our first steps on the moon is helping Earth cope with the deluge of radio signals that will be beamed back.
The U.S. Ambassador, Tom Schieffer, today launches a Mars tracking program to be carried out by CSIRO's Parkes Observatory , west of Canberra, ACT, on behalf of NASA.
Between 3 November 2003 and February 2004, the Parkes Radio Telescope will track and receive radio signals from the Mars Odyssey and Mars Global Surveyor, both already in orbit around Mars. The European Mars Express is due to arrive in the vicinity of Mars on Christmas Day, and the Mars Exploration Rover is due there in January. In addition Parkes will also track Voyager 2, another NASA spacecraft that is not near Mars but in the same part of the sky.
In return for Parkes' involvment, an upgrade of the Parkes Telescope as part of a $3m deal with NASA will quadruple the sensitivity of the instrument in the high frequency range.

It was NASA's Pioneer 10 spacecraft, struggling to communicate with ground controllers, its message riding on a radio signal that registered just a billionth of a trillionth of a watt. How do you listen to a transmission that couldn't make a lightbulb glow in a billion years? It's all in a day's work for NASA's extraordinary Deep Space Network (DSN). Right : A 70-meter antenna at the Deep Space Network Goldstone complex in California. The DSN is a global system for communicating with interplanetary spacecraft. The largest and most sensitive scientific telecommunications system in the world, it also performs radio and radar astronomy observations for the exploration of the solar system and the universe. "Communicating with missions in deep space is difficult," said Joseph Statman, Manager of the Deep Space Mission System Engineering Office at NASA's Jet Propulsion Laboratory (JPL). "It requires extremely large antennas, huge transmitters and very sensitive receivers."

    The Tracking and Data Relay Satellite (TDRS) system represents a new era in tracking Earth-orbiting spacecraft, including the Space Shuttle, and transmitting their data back to Earth. The TDRS concept was conceived following early 1970s studies which showed that a system of orbiting telecommunications satellites, operated from a single ground terminal link, could more effectively support Space Shuttle, scientific and other NASA mission requirements than the nearly 25-year-old tracking and communications network of ground stations located worldwide. The TDRS network provides almost full-time coverage not only for the Shuttle, but also for typically up to 24 other orbiting spacecraft simultaneously. Services provided include communications, tracking, telemetry and data acquisition. The TDRS satellites orbit geosynchronously at 22,300 statute miles (35,888 kilometers) above the Earth and look down on an orbiting Shuttle or spacecraft. This means that for most of their orbits around the Earth, these spacecraft will remain in sight of one or more TDRS satellites.

    The Mariner IV spacecraft, having achieved its mission objectives and now in its 300th day of flight, will receive a command from Earth next week, concludingbut possibly only temporarilythe National Aeronautics and Space Administration's longest and most complex deep space mission.
    Since launch November 28, 1964, Mariner IV has transmitted to Earth nearly 50 million engineering and scientific measurements on the environment of interplanetary space and in the vicinity of Mars. It flew past Mars last July 14 at an altitude of 6118 miles, recording the first close-up pictures of the planet's surface.
    After October 1, when the ground command switches the spacecraft transmitter from Mariner's high-gain directional antenna to an omnidirectional antenna, telemetry from Mariner IV will cease.
    Although next week will mark the end of useful telemetry between Mariner IV and Earth during 1965, project officials at the Jet Propulsion Laboratory said the spacecraft will continue transmitting and may renew its radio link with Earth in 1967.

    Belinda Arroyo is in charge of the team that negotiates tracking time with the Deep Space Network for 12 NASA missions. May 10, 2002 - So many spacecraft - so little time - tracking time, that is. It's something of a luxury these days because of the dozens of space missions sprinkled around the solar system routinely competing for the undivided attention of the few antennas capable of communicating with their spacecraft. Negotiating tracking time is what Belinda Arroyo's team does for a living. She is the team chief of the Mission Management Office Multi-Mission DSN Allocation and Planning Team, an organization that makes sure that the 12 NASA missions for which they are responsible have adequate time allotted with the Deep Space Network. Managed by NASA's Jet Propulsion Laboratory, the Deep Space Network has three sites disseminated in key areas of the world Spain, Australia and California. To communicate with spacecraft, each site has a 70-meter (230-foot) in diameter antenna and a variety of smaller ones. Arroyo is so good at what she does that she is even attributed special powers by those JPL team members who depend on her skills to communicate with their spacecraft roaming the solar system.

    A Lockheed Martin Atlas 2A rocket soared into the Central Florida morning sky Friday on a $395 million mission to fortify NASA's communications relay link between Earth and space. The rocket scored its 51st straight success by delivering the Tracking and Data Relay Satellite-H, or TDRS-H for short, in the planned geosynchronous transfer orbit around the planet. Liftoff from Cape Canaveral Air Force Station's pad 36A occurred at 8:56 a.m. EDT (1256 GMT), some 18 minutes late due to a boat that had to be chased from the restricted launch danger zone in the Atlantic Ocean. Read our Mission Status Center for a play-by-play description of the countdown launch. Ground controllers quickly established contact with the new TDRS satellite, confirming its health following the launch. Efforts then began to unfurl the two 15-foot antenna reflectors on the satellite. At about 1:51 p.m. EDT, the mesh structures, which were folded like a taco for launch, sprung into shape after straps holding them in place were cut. Over the coming two weeks the onboard kick engine will fire several times to boost the satellite's orbit to geostationary altitude at 22,300 miles above the equator. The craft will be parked initially at 150 degrees West longitude to undergo several months of testing and checkout. It will also receive a new designation: TDRS-8.
