Hold Me Closer, Tiny Thruster
2012-08-17 13:13:07

Michael Harper for redOrbit.com — Your Universe Online Some MIT engineers have taken the old cliche “Good things come in small packages” to heart, creating a rocket thruster no larger than an American penny or postage stamp. These thrusters, which operate on jets of ion beams, could soon power some of the tiniest satellites in space. These “micro thrusters” were created by Paulo Lozano, an associate professor of aeronautics and astronautics at MIT....

NASA is seeking proposals for small satellite payloads to fly on rockets planned to launch between 2013 and 2016. These miniature spacecraft, known as CubeSats, could be auxiliary payloads on previously planned missions. CubeSats are a class of research spacecraft called nanosatellites. These cube-shaped satellites are approximately four inches long, have a volume of about one quart and weigh less than three pounds. Proposed CubeSat investigations must be consistent with NASA's...

Lee Rannals for redOrbit.com - Your Universe Online NASA announced that it has chosen three teams for small spacecraft technology demonstration missions. The space agency chose the teams to advance the state of the art for small spacecraft in the areas of communications, formation flying and docking systems. It said the space technology flights are expected to start taking place sometime between 2014 and 2015. All of the selected missions will employ nanosatellites conforming to...

CINEMA Nanosatellite Part Of Group Of CubeSats To Go Into Space
2012-08-01 08:33:58

Lawrence LeBlond for redOrbit.com - Your Universe Online University of California, Berkeley students are part of an international team of students that built an 8-pound satellite that will be launched into orbit tomorrow (August 2) along with ten other CubeSats -- a new line of inexpensive, modular nanosatellites. The nanosatellites will accompany a spy satellite aboard an Atlas V rocket being launched from Vandenberg Air Force Base (VAFB) in California. The nanosatellite, called CINEMA...

When you consider the cost of launching a satellite, it´s small wonder that ESA is looking to keep them working as long as possible. For satellites offering communications services that are bought and paid for, this extended life is critical. Now there is a solution. Communication satellites are often placed in the unique ℠geostationary orbit´, almost 36 000 km above the equator where their speed matches Earth´s 24-hour spin. From our viewpoint, they appear to sit...

Iridium Satellite -- The Iridium satellite constellation is also a system of 66 active communication satellites and spares around the earth. Named for the element Iridium, it was originally to have 77 active satellites, but was later redesigned to have its current number, though the name was retained. Iridium allowed worldwide voice and data communications using handheld devices. The Iridium service once failed financially and the earth stations were shut down. Its financial...

Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
