NASA Prepares for First Interplanetary CubeSats on Agency’s Next Mission to Mars

When NASA launches a subsequent goal on a tour to Mars – a still lander in 2016 – a moody will embody dual CubeSats. This will be a initial time CubeSats have flown in low space.  If this flyby proof is successful, a record will yield NASA a ability to fast broadcast standing information about a categorical upholder after it lands on Mars.

The twin communications-relay CubeSats, being built by NASA’s Jet Propulsion Laboratory (JPL), Pasadena, California, consecrate a record proof called Mars Cube One (MarCO).  CubeSats are a category of upholder formed on a standardised tiny distance and modular use of off-the-shelf technologies. Many have been done by university students, and dozens have been launched into Earth circuit regulating additional cargo mass accessible on launches of incomparable spacecraft.

The simple CubeSat section is a box roughly 4 inches (10 centimeters) square. Larger CubeSats are multiples of that unit. MarCO’s pattern is a six-unit CubeSat – about a distance of a briefcase — with a stowed distance 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 Mar 2016 from Vandenberg Air Force Base, California on a same United Launch Alliance Atlas V rocket as NASA’s Interior Exploration regulating Seismic Investigations, Geodesy and Heat Transport (InSight) lander. Insight is NASA’s initial goal to know a interior structure of a Red Planet. MarCO will fly by Mars while InSight is landing, in Sep 2016.

“MarCO is an initial capability that has been combined to a InSight mission, though is not indispensable for goal success,” pronounced Jim Green, executive of NASA’s heavenly scholarship multiplication during a agency’s domicile in Washington. “MarCO will fly exclusively to Mars.”

During InSight’s entry, skirmish and alighting (EDL) operations on Sept. 28, 2016, a lander will broadcast information in a UHF radio rope to NASA’s Mars Reconnaissance Orbiter (MRO) drifting overhead. MRO will brazen EDL information to Earth regulating a radio magnitude in a X band, though can't concurrently accept information over one rope while transmitting on another. Confirmation of a successful alighting could be perceived by a orbiter some-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 able of immediately relaying information perceived over UHF.

The dual CubeSats will apart from a Atlas V upholder after launch and transport along their possess trajectories to a Red Planet. After recover from a launch vehicle, MarCO’s initial hurdles are to muster dual radio antennas and dual solar panels. The high-gain, X-band receiver is a prosaic row engineered to approach radio waves a approach a parabolic plate receiver does. MarCO will be navigated to Mars exclusively of a InSight spacecraft, with a possess march adjustments on a way.

Ultimately, if a MarCO proof goal succeeds, it could concede for a “bring-your-own” communications send choice for use by destiny Mars missions in a vicious few mins between Martian windy entrance and touchdown.

By verifying CubeSats are a viable record for interplanetary missions, and possibly on a brief growth timeline, this record proof could lead to many other applications to try and investigate the solar system.
