Hola amigos: A VUELO DE UN QUINDE EL BLOG., hemos recibido información de la Agencia Espacial NASA, sobre la próxima misión que tiene la Agencia en su Misión a Marte, se utilizará unos módulos que ellos denominan: CubeSats.
Cuando la NASA lanza su próxima misión en el viaje a Marte - un módulo de aterrizaje fijo en 2016 - el vuelo incluirá dos CubeSats. Esta será la primera vez; CubeSats han volado en el espacio profundo. Si esta demostración sobrevuelo tiene éxito, la tecnología de la NASA proporcionará la capacidad de transmitir con rapidez información de estado sobre la nave principal después de que aterrice en Marte.

NASA's two small MarCO CubeSats will be flying past
Mars in 2016 just as NASA's next Mars lander, InSight, is descending
through the Martian atmosphere and landing on the surface. MarCO, for
Mars Cube One, will provide an experimental communications relay to
inform Earth quickly about the landing.

When NASA launches its next mission on the journey to Mars – a
stationary lander in 2016 – the flight will include two CubeSats. This
will be the first time CubeSats have flown in deep space. If this flyby
demonstration is successful, the technology will provide NASA the
ability to quickly transmit status information about the main spacecraft
after it lands on Mars.
The twin communications-relay CubeSats, being built by NASA's Jet
Propulsion Laboratory (JPL), Pasadena, California, constitute a
technology demonstration called Mars Cube One (MarCO). CubeSats are a
class of spacecraft based on a standardized small size and modular use
of off-the-shelf technologies. Many have been made by university
students, and dozens have been launched into Earth orbit using extra
payload mass available on launches of larger spacecraft.
The full-scale mock-up of NASA's MarCO CubeSat held
by Farah Alibay, a systems engineer for the technology demonstration,
is dwarfed by the one-half-scale model of NASA's Mars Reconnaissance
Orbiter behind her.

The basic CubeSat unit is a box roughly 4 inches (10 centimeters)
square. Larger CubeSats are multiples of that unit. MarCO's design is a
six-unit CubeSat – about the size of a briefcase -- with a stowed size
of about 14.4 inches (36.6 centimeters) by 9.5 inches (24.3 centimeters)
by 4.6 inches (11.8 centimeters).
MarCO will launch in March 2016 from Vandenberg Air Force Base,
California on the same United Launch Alliance Atlas V rocket as NASA’s
Interior Exploration using Seismic Investigations, Geodesy and Heat
Transport (InSight) lander. Insight is NASA’s first mission to
understand the interior structure of the Red Planet. MarCO will fly by
Mars while InSight is landing, in September 2016.
“MarCO is an experimental capability that has been added to the
InSight mission, but is not needed for mission success,” said Jim Green,
director of NASA’s planetary science division at the agency’s
headquarters in Washington. “MarCO will fly independently to Mars."
During InSight’s entry, descent and landing (EDL) operations on Sept.
28, 2016, the lander will transmit information in the UHF radio band to
NASA's Mars Reconnaissance Orbiter (MRO) flying overhead. MRO will
forward EDL information to Earth using a radio frequency in the X band,
but cannot simultaneously receive information over one band while
transmitting on another. Confirmation of a successful landing could be
received by the orbiter more than an hour before it’s relayed to Earth.
MarCO’s radio is about softball-size and provides both UHF (receive
only) and X-band (receive and transmit) functions capable of immediately
relaying information received over UHF.
The two CubeSats will separate from the Atlas V booster after launch
and travel along their own trajectories to the Red Planet. After release
from the launch vehicle, MarCO's first challenges are to deploy two
radio antennas and two solar panels. The high-gain, X-band antenna is a
flat panel engineered to direct radio waves the way a parabolic dish
antenna does. MarCO will be navigated to Mars independently of the
InSight spacecraft, with its own course adjustments on the way.
Ultimately, if the MarCO demonstration mission succeeds, it could
allow for a “bring-your-own” communications relay option for use by
future Mars missions in the critical few minutes between Martian
atmospheric entry and touchdown.
By verifying CubeSats are a viable technology for interplanetary
missions, and feasible on a short development timeline, this technology
demonstration could lead to many other applications to explore and study
our solar system.
JPL manages MarCO, InSight and MRO for NASA's Science Mission
Directorate in Washington. Technology suppliers for MarCO include: Blue
Canyon Technologies of Boulder, Colorado, for the attitude-control
system; VACCO Industries of South El Monte, California, for the
propulsion system; AstroDev of Ann Arbor, Michigan, for electronics; MMA
Design LLC, also of Boulder, for solar arrays; and Tyvak Nano-Satellite
Systems Inc., a Terran Orbital Company in San Luis Obispo, California,
for the CubeSat dispenser system.
