Free Software on the final frontier: GNU Radio controls the ISEE-3 Spacecraft

Equipped with free GNU Radio software, a group of citizen scientists has contacted, controlled, and is attempting to recapture a 1970s-era satellite and bring it back into an orbit close to Earth.























The ISEE-3 spacecraft
An original drawing of the ISEE-3 spacecraft from the 1970s.



The International Sun-Earth Explorer-3, or ISEE-3, was launched in 1978 by NASA to monitor activity on the sun. After three years of observation, NASA repurposed the satellite, which soon became the first spacecraft to visit a comet. The mission ended in 1999, when NASA abandoned ISEE-3 to orbit the Sun, despite the fact that twelve of the satellite's thirteen instruments were still working.


In 2008, when it was discovered that the satellite was still transmitting a signal and would fly close to Earth, NASA realized that they no longer had the funding or equipment to reinitiate contact. So a volunteer group of scientists, programmers, and engineers organized the ISEE-3 Reboot Project, which was crowd-funded with over $150,000 in donations, and set out to contact the spacecraft, fire its engine, and bring it closer to Earth to resume its original mission.


To do this, the group turned to GNU Radio, a free software toolkit for implementing software-defined radios and signal processing systems. Modifying the software to communicate in the 1970s satellite protocol, members of the reboot project were able to gain access to the spacecraft and fire its thrusters in early July, and will soon attempt to move the satellite into an orbit close to Earth.


You can support GNU Radio by making a donation through the FSF's Working Together for Free Software Fund. To get more involved, attend the annual GNU Radio Conference, to be held this year between September 15th and 19th in Washington, D.C.


The successes of the ISEE-3 Reboot project demonstrate the importance of developing, maintaining, and promoting free software. With dozens of contributors and thousands of users, GNU Radio is written to be shared, learned, and improved by anyone, anywhere -- unlike the lost proprietary communications equipment used by NASA.


This is the second time we've lauded the use of free software for space exploration in the last two years. Read our 2013 blog post about the choice of GNU/Linux as the operating of the International Space Station.


"This openness to inquiry, collaboration, and 'standing on the shoulders of giants' is at the heart of all science," wrote John Gilmore, a founding member of the GNU Radio project, in an email to the FSF. "The GNU Project has institutionalized those principles in a vast community of software authors and users. And GNU's legalized freedom and sharing [...] enable many people to use it and contribute to it -- such as these volunteers."

GNU/Linux chosen as operating system of the International Space Station

This is a wise choice for the space station, and a high-profile victory for software freedom. It brings good publicity for free software, demonstrating its respected position in the world of science and technology.


















The International Space Station, now using GNU/Linux

While "use it on a space station" wasn't listed as one of RMS's "Measures Governments Can Use to Promote Free Software", the announcement that the International Space Station is switching its laptops from Windows XP to GNU/Linux is exciting news. It's especially important for governments to use free software, because everything they do is paid for by the citizens of their countries. To ask citizens to pay for software that they cannot use, study and modify is especially unjust.



Along with increased reliability, NASA said they chose GNU/Linux because they could modify it to fit their needs. This is one of the core ideas behind free software, and we're glad the space agency values it.



Unfortunately, both NASA and the media writing about the decision have been calling the operating system "Linux" instead of "GNU/Linux." The kernel Linux is an important part of the operating system known as GNU/Linux, but the vision of the system and the framework on which the system is made were developed by the GNU Project, a community of developers that care deeply about free software ideas. Because of this, it is inaccurate to refer to the OS as "Linux," and doing so covers up the fact that this space-worthy operating system is the result of a decades-long commitment to ethical values.



That's why we ask that, when you talk or write about the operating system (in space or otherwise), you help us by referring to it as "GNU/Linux," and encourage your friends to do the same. There are gnus up there in space, along with the penguins.



Ironically, even though NASA calls the operating system by a misleading name, the distribution they chose, Debian, gets this right -- its official name is Debian GNU/Linux.



To learn more about this naming problem, see "Linux and GNU", the GNU/Linux FAQ or the history of the GNU Project on GNU.org.
