Nasa is flying Kicksat for free as part of its Educational Launch of Nanosatellites programme. Once in orbit, the Falcon 9 will release the Dragon towards the ISS and,
and launched its first small satellite in 2003. The satellites it put into the space provide everything from high-resolution imagery to monitor the country's shrinking farmland, to cheaper wireless and internet coverage.
and now Richard Branson and Virgin galactic are pursuing microsatellite clusters. Earlier this week the 64-year-old billionaire announced a partnership with satellite-system designers Oneweb to use Virgin galactic's Launcherone rocket to create a massive satellite constellation in space.
The project would deploy a fleet of 648 microsatellites capable of providing low-latency high-speed Internet access directly to small user-based terminals all around the world.
which slightly turns the microsatellites to avoid interference. The cluster which would be the world's largest satellite network will then talk to receivers on the ground measuring a tiny 36 centimeters by 16 centimeters
#How to cash in on cheap Earth-watching satellites THERE ARE some big plans brewing for small satellites. With hordes of cheap orbiters filling the skies researchers
The satellite's design is an iteration of the diminutive 10-centimetre Cubesats that have been used for scientific research since 2003.
But it could later switch to satellites like the 28 imaging cubesats that the firm Planet Labs of San francisco already has in orbit.
#Boxy Cubesats get a propulsion boost in new space race Tiny liquid volcanoes that spray beams of charged particles could make space history next year.
They are one of two technologies vying to be the first to let cheap, miniature satellites called Cubesats fly in formation,
Paulo Lozano leads a team working on Cubesat propulsion at the Massachusetts institute of technology. He has been given the go-ahead to launch two propelled Cubesats in 2014 one funded by the US Department of defense
the other by private donors. Meanwhile, Benjamin Longmier at the University of Michigan in Ann arbor, who leads a rival project, announced that his team also has private funding
and a slot to launch their Cubesat on a NASA rocket next year. The race is on.
Cubesats are made from off-the-shelf components. The initial aim was to make access to space easier and more affordable.
Although they have made space accessible to groups who wouldn't otherwise have been able to afford it most recently a team of high-school students Cubesats haven't done much cutting-edge science."
Some Cubesats have basic steering, but getting them to change orbits, let alone visit other planetary bodies,
That's because even today's most efficient propulsion method, the ion engine, doesn't scale down to Cubesat size.
The result is an array of between 500 and 5000 focussed ion beams that stream from each of the eight chips on the Cubesat when the electric field the strength

Their Cubesat Ambipolar Thruster, or CAT, uses xenon, like traditional ion engines. The difference is that the CAT adds an intense
They hope their propelled Cubesats will one day fly to Saturn's moon Enceladus and Jupiter's moon Europa, both
A fleet of Cubesats with propulsion in orbit around a planet or moon can do a lot of things that big expensive satellites cannot, such as monitoring several locations in the atmosphere at once.
Propelled Cubesats could even be useful back here On earth. Creating a universal"satellite Wi-fi""like existing satellite phone coverage,
But you could dump a thousand Cubesats in one place then spread them out to the right points, for a fraction of the price.
and propel the Cubesat next year.""We might have a little space race on our hands,
Known as Cubesats each mini satellite packs an array of devices including cameras spectrometers and a Geiger counter into a cube just 10 centimetres to a side.
The cargo ship carrying the Cubesats should arrive at the ISS on 9 august and the satellites will then be deployed using a robotic-arm technique tested last year.
The method can put several small satellites into orbit around Earth eliminating the need for dedicated launch vehicles and making citizen-science missions like Ardusat more affordable.
and build Cubesats for planetary science. This definitely is helping open up space both to all people
if companies make their equipment small enough to fit in Cubesats small, lightweight satellites that can piggyback on the launches of other vehicles."
"That way every rocket that goes up is kicking off Cubesats, "he says, with each small orbiter perhaps holding only a fraction of a functional communications rig."

The Cygnus cargo vehicle destroyed on this accident was carrying a lot of small satellites owned by schools universities and startups.
For example Planet labs an earth imaging startup lost 26 small satellites that were on board. Orbital stated that the payload is insured
Already this year, wee seen a $50m investment into drone maker 3d Robotics and a $95m investment into microsatellite company Planet Labs, both of which count agriculture as key early market opportunities.
#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,
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.
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.
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.
and back on a tank of fuel but its first application may be shunting networks of small satellites around in Earth orbit.
#Electrospray thruster makes small satellites more capable Small satellites are becoming increasingly popular tools for Earth-imaging, communications,
Now Accion has developed a commercial electrospray propulsion system their first is about the size of a pack of gum made of tiny chips that provide thrust for small satellites.
and resources a small satellite already has, says Accion technical advisor Paulo Lozano, an associate professor of aeronautics and astronautics who invented the underlying technology.
But in space, it can push around a Cubesat, or a slightly larger satellite. The module has a plastic tank that stores a nontoxic
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,
where they burn up, Brikner says. However, with dozens of small satellites being launched annually, Lozano adds, the system could also help control how long they stay in space,
so they don become floating space junk. ou can climb to an orbit where drag is less,
which are allowed not to piggyback on the larger rockets that carry small satellites into space. o theye easy to produce,
a startup that aimed to make chemical-based launchers for small satellites. It closed soon after it started. never thought I have another chance to do a space-propulsion company,
In the future, Lozano says Accion system could enable small satellites to perform tasks now possible only for much larger satellites such as exploring the moon.
Small satellites aren yet able to reach the appropriate orbit for such missions. ut if youe stuck in an orbit you don want,
#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.
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
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
or to de-orbit it at the end of its life. t produces the force it should be producing given the amount it was told emitting,
and basic science at Virginia Tech Carilion Medical school, analyzed an often ignored part of the human genome repetitive DNA sequences referred to as microsatellites.
More than 1 million microsatellites exist in the human genome including in neural crest tissues, a thin layer of cells within an embryo that contains genetic instructions to build hundreds of cell types, from neurons to adrenal cells.
or predicted from specific markers within these repetitive sequences, known as cancer-associated microsatellite loci, or CAML.
microsatellites are known for their role in certain diseases such as Fragile X and Huntington disease. Garner group has shown that these regions can be informative about diseases ranging from cancer to autism spectrum disorder.
microsatellites. Arx Pax is partnering up with NASA to explore how its technology could be used to move around tiny satellites in space using the MFA technology.
Cubesats can be as little as 10cm square, and the hover engine also isn't meant to work over large distances either."
#NASA Cubesat initiative aids in testing of technology for solar sails in space With help from NASA, a small research satellite to test technology for in-space solar propulsion launched into space May 20 aboard an Atlas v
as part of the agency Cubesat Launch Initiative. The Atlas v sent the U s. Air force X-37b space plane on its fourth mission,
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
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.
the Cubesat Launch Initiative has selected 110 Cubesats primarily from educational and government institutions around the United states. NASA will announce the next call for proposals in August 2015
Planetiq's microsatellite constellation, with an initial set of 12 satellites launching in 2016 and 2017, will deliver over 8 million observations per day of temperature, pressure and water vapor,
