#First nanosatellite functional: Nasa WASHINGTON: A miniature satellite sent in the space aboard an Atlas v rocket from the Vandenberg Air force base in California on October 8 is working fine,
Nasa has announced. The Optical Communications and Sensor Demonstration (OCSD) Cubesat spacecraft is in orbit and operational, said Nasa and The Aerospace Corporation of El Segundo, California on Monday.
Cubesats are going to play a key role in exploration, technology demonstration, scientific research and educational investigations.
They provide a low-cost platform for Nasa missions, including planetary space exploration, Earth observations, fundamental Earth and space science."
Cubesats also allow an inexpensive means to engage students in all phases of satellite development, operation and exploitation through real-world, hands-on research and development experience.
OCSD is the first in a new series of six Nasa-managed technology demonstration missions set to be launched during the coming months using Cubesats.
These will test technologies that can enable new uses for these miniature satellites which measure about four inches per side.
and the orientation of the Cubesat controls the direction of the beam. This makes the laser system more compact than anything previously flown in space.
The Cubesat will evaluate the ability to point a small satellite accurately as it demonstrates data transfer by laser at rates of up to 200 mb per second--a factor of 100 increase over current high-end Cubesat communications systems.
Among other unique features of the Ultrascope include its ability to communicate with satellites to determine its exact location On earth.

The second part of Mr Debney's plan is to place a satellite in geostationary orbit, and lower a cable from it to the ground.

but more modern satellites have relied upon a mix of chemical and electric propulsion. Now Boeing has announced the first all-electric ion propulsion satellite is fully operational.
The satellite in question doesn have a snappy name it a communications satellite called ABS-3a 702sp.
It was launched last March aboard a Spacex Falcon 9 rocket. It has just recently been handed over to its owner
Bermuda-based telecommunications company ABS. Because ABS-3a is a communications satellite, it needs to remain in a geosynchronous orbit.
meaning it can remain operational much longer than a similar satellite with conventional thrusters. ABS expects the satellite to remain active for about 15 years.
Ion thrusters are also considerably lighter than chemical engines making launches cheaper. The drawback is the very low thrust of an ion engine.
That why past satellites have carried conventional thrusters as well. Upon delivery to orbit, ABS-3a used its ion thrusters to reach a geosynchronous orbit at 3 degrees west longitude.
the satellite was turned over to ABS on August 31st. Now that the design has proven itself viable,
Boeing is forging ahead with a second satellite for ABS using the same XIPS engines.
For scientists on the ground, the necessity of bouncing signals through multiple orbiting satellites means that rover missions progress as a series of quick snapshots, with tense waits in between.
For that power commitment, it will purportedly be able to maintain a signal with a satellite around Earth, 225 million kilometers away.

#Electrospray thruster makes small satellites more capable Small satellites are becoming increasingly popular tools for Earth-imaging, communications,
What these satellites lack is a viable propulsion system, says MIT aeronautics and astronautics alumna Natalya Brikner Phd 5,
cofounder and CEO of Accion Systems. ou can make a satellite the size of a softball with a surprising amount of capabilities,

This technology could enable low-cost satellites, such as those known as ubesats, to become more viable for various commercial

But in space, it can push around a Cubesat, or a slightly larger satellite. The module has a plastic tank that stores a nontoxic
nonvolatile, liquid-salt propellant. Above the reservoir are the chips, which each have a porous substrate with about 500 pointed tips and, above that, an extractor grid with small holes.
to stabilize a Cubesat launched from the International space station, and to compensate for atmospheric drag, hich is the force that pulls small satellites into the atmosphere prematurely,

#First pocket rockets take tiny satellites for a spin The next giant leap in space exploration could start with a small spin around the lab. A new propulsion system for shrunk-down satellites called Cubesats just passed a key lab test,
Cubesats, cheap, simple satellites built from off-the-shelf parts, promise a revolution in space exploration but only if only we can steer them.
About 10 of the 1-kilogram satellites can hitch a ride into space with a larger payload.
but Cubesats can become dangerous space junk. f little satellites had the capability to move, we could do a lot of things that currently we cannot,
So Lozano and his colleagues are designing a miniature propulsion system small enough to fit in your pocket that can steer Cubesats around low-Earth orbit
Applying an electric field can send these ions streaming away from the satellite at high speeds
This August, Lozano and his students tested the complete system, Cubesat and all. They put it in a vacuum chamber
and placed the thrusters on opposite sides of the Cubesat to push it in a circle, rather than having it fly around the lab. One thruster emitted positive ions
and the other negative ones, keeping the Cubesat neutrally charged. After 20 minutes of continuous firing, the Cubesat spun at about 2 rotations per minute.
Lozano says this would be enough to take a Cubesat from an altitude of 400 kilometres up to 800 kilometres

The Planetary Society Lightsail satellite is a technology demonstration for using solar propulsion on Cubesats, a class of research spacecraft called nanosatellites.
NASA selected Lightsail as part of the agency Cubesat Launch Initiative, which provides opportunities for small satellites to fly as auxiliary payloads on planned missions.
It was assigned to a launch as part of as the 11th installment of the Educational Launch of Nanosatellite (ELANA) mission.
The upper stage of the Atlas v included the National Reconnaissance Office third auxiliary mission to launch Cubesats.
The Ultra Lightweight Technology and Research Auxiliary Satellite (ULTRASAT) carried 10 Cubesats including Lightsail from five organizations.
It was made possible through agreements between NASA the Air force Space and Missile Systems Center and the National Reconnaissance Office to work together on Cubesat integration and launch opportunities.
The cube-shaped satellites measure about four inches on each side, have a volume of about one quart
and weigh less than three pounds each. Lightsail consists of three Cubesats bundled together. Individual Cubesat research projects may address science, exploration, technology development or education.
During the next month, the Lightsail team will receive data from the satellite in space. As part of its agreement with NASA, the Planetary Society will provide the agency a report on outcomes and scientific findings.
Since its inception in 2010 the Cubesat Launch Initiative has selected 110 Cubesats primarily from educational
