NASA’s Space Cubes: Small Satellites Provide Big Payoffs

Good things unequivocally do come in tiny packages.

When we consider of space satellites that support with communications, continue monitoring and GPS here on Earth, we expected design them as being utterly large—many are as large as a propagandize train and import several tons. Yet there’s a category of smaller satellites that’s flourishing in popularity. These miniaturized satellites, famous as nanosatellites or CubeSats, can fit in a palm of your palm and are providing new opportunities for space science.

“CubeSats are partial of a flourishing record that’s transforming space exploration,” pronounced David Pierce, comparison module executive for suborbital examine during NASA Headquarters in Washington. “CubeSats are tiny platforms that capacitate a subsequent era of scientists and engineers to finish all phases of a finish space idea during their propagandize career. While CubeSats have historically been used as training collection and record demonstrations, today’s CubeSats have a intensity to control vicious space scholarship investigations as well.”

CubeSats are built to customary specifications of 1 section (U), that is equal to 10x10x10 centimeters (about 4x4x4 inches). CubeSats can be 1U, 2U, 3U or 6U in size, weighing about 3 pounds per U. They mostly are launched into circuit as auxiliary payloads aboard rockets, significantly shortening costs.

Because of a smaller cargo and reduce cost tag, CubeSat record allows for experimentation. “There’s an event to welcome some risk,” pronounced Janice Buckner, module executive of NASA’s Small Innovative Missions for Planetary Exploration (SIMPLEx) program. “These mini experiments element NASA’s incomparable assets.”

Another advantage of a “smaller is bigger” judgment is it’s some-more inclusive. The low cost and comparatively brief smoothness time from judgment to launch – typically 2-3 years – allows students and a flourishing village of citizen scientists and engineers to minister to NASA’s space scrutiny goals, partial of a White House’s Maker Initiative. By providing hands-on opportunities for students and teachers, NASA helps attract and keep students in science, technology, engineering and math disciplines, strengthening NASA’s and a nation’s destiny workforce.

This inclusiveness also relates to geography. In 2014 NASA announced a enlargement of a CubeSat Launch Initiative, with a idea of rising 50 tiny satellites from 50 states within 5 years. To date NASA has comparison CubeSats from 30 states, 17 of that have already been launched. Two some-more — Alaska and Maryland — are slated to go to space after this year, including a initial ever CubeSat launched by an facile school.

In Apr 2015 a SIMPLEx module requested proposals for interplanetary CubeSat investigations, with a row of NASA and other scientists and engineers reviewing 22 submissions. Two were chosen—one led by a postdoctoral examine scientist and a other a university professor. NASA Headquarters, Planetary Science Division, also comparison 3 record developments for probable destiny heavenly missions: one to   expand NASA’s ability to examine Mars’ atmosphere, one to examine a hydrogen cycle during a moon and one to perspective a tiny near-Earth asteroid. Each comparison group will accept one year of appropriation to move their particular technologies to a aloft turn of readiness. To be deliberate for flight, teams contingency denote swell in a destiny idea offer competition.

The CubeSat investigations comparison for a heavenly scholarship idea event are:

  •  Lunar Polar Hydrogen Mapper (LunaH-Map), a 6U-class CubeSat that will enter a frigid circuit around a moon with a low altitude (3-7 miles) centered on a lunar south pole. LunaH-Map carries dual proton spectrometers that will furnish maps of near-surface hydrogen. LunaH-Map will map hydrogen within craters and other henceforth shadowed regions via a south pole. Postdoc Craig Hardgrove from Arizona State University (ASU), Tempe, Arizona, is a principal investigator. ASU will conduct a project.
  •  CubeSat Particle Aggregation and Collision Experiment (Q-PACE) is a 2U-class, thermos-sized, CubeSat that will try a elemental properties of low-velocity molecule collision in a microgravity environment, in an bid to improved know a mechanics of early world development. Josh Colwell from a University of Central Florida (UCF), Orlando, Florida, is a principal investigator, and UCF will conduct a project.

The proposals comparison for serve record growth are:

  • The Mars Micro Orbiter (MMO) mission, that uses a 6U-class Cubesat to magnitude a Martian atmosphere in manifest and infrared wavelengths from Mars orbit. Michael Malin of Malin Space Science Systems, San Diego, California, is a principal investigator.
  • Hydrogen Albedo Lunar Orbiter (HALO) is a propulsion-driven 6U-class CubeSat that will answer vicious questions about a lunar hydrogen cycle and a start of H2O on a lunar aspect by examining a reflected hydrogen in a moon’s solar wind. The principal questioner is Michael Collier of NASA’s Goddard Space Flight Center, Greenbelt, Maryland.
  • Diminutive Asteroid Visitor regulating Ion Drive (DAVID) is a 6U-class CubeSat idea that will examine an asteroid most smaller than any complicated by prior booster missions and will be a initial NASA idea to examine an Earth-crossing asteroid. Geoffrey Landis of NASA’s Glenn Research Center, Cleveland, Ohio, is a principal investigator.

“These selections will capacitate a subsequent era of heavenly scientists and engineers to use insubordinate new idea concepts that have a intensity to lapse unusual science,” pronounced Buckner. “CubeSats are going to impact a destiny of heavenly exploration.”
