Off-the-Shelf Components Connect NASA Wireless Experiment

Did you know NASA’s XBee network that was deployed 200 miles above Earth was constructed completely out of off-the-shelf components?

As part of a NASA initiative to efficiently experiment with new ideas and technologies, the development team created their entire network out of commercial off-the-shelf components.  Using devices like Arduino and XBee, the engineering team was able to create a network to reliably gather critical data on Exo-Brake technology.

An Arduino Mega processed data and acted as the gateway’s engine, which connected the local XBee network to the long-range Iridium satellite uplink. As seen in the diagram above, the gateway was placed within the payload of the Exo-Brake and gathered sensor data from three XBees-3-axis acceleration, temperature and pressure. Data was then sent back down to mission control for analysis.

XBee Takes Flight at NASA Wallops Flight Facility

Posted on:

You may remember this post from last year sharing the upcoming NASA experiment involving XBee. Well, after a few delays (launching rockets is complicated!), XBee finally took flight. XBee-Launch-Space

Early in the morning on July 7, NASA launched a NASA Black Brant IX suborbital sounding rocket from their Wallops Flight Facility. Onboard the rocket was an experiment testing Exo-Brake technology. XBee was used to collect sensor data including temperature, air pressure, and 3-axis acceleration parameters.

NASA is considering Exo-brakes as a possible solution for returning cargo from the International Space Station (ISS), orbiting platforms or as possible landing mechanisms in low-density atmospheres. This was one of many tests used to analyze its effectiveness, but the first to incorporate an XBee connected sensor network. If you would like to read more about the Exo-brake, check out this article.
