"The ISEE-3 spacecraft was launched by NASA in 1978 to study the the interaction between the Earth's magnetic field and the solar wind and was operated up to the year 1997. In 2014 it was discovered that the probe wasn't deactivated and was emitting radio signals. A group of Citizen Scientists crowdfunded the ISEE-3 reboot project, earning enough money to buy and build equipment to reestablish contact and take control of the spacecraft."

Communication with the ISEE-3 satellite was successfully re-established with the goal of commanding the satellite to change its trajectory with the goal of putting it into a libration point orbit that would allow it to resume its original mission goals of collecting data for solar physics research. The trajectory change goal unfortunately could not be completed due to the failure of the onboard thrusters. This failure was apparently the result of the loss of nitrogen pressurant in the Hydrazine fuel system.
This inability to change the spacecraft's orbit rules out the original reboot mission goals which would have provided long-term data collection from the satellite instrumentation package using modest antennas. After the orbit change attempt, the ISEE-3 Reboot Team powered on the instrumentation package and began data collection from the instruments to assess their current physical status and usefulness for any ongoing scientific mission. We are now redefining our mission goals to obtain the maximum scientific usefulness of ISEE-3 in its new interplanetary orbit. Figure 1 shows the flyby orbit and the long-term sun centered (heliocentric) orbit.
We're organizing our international citizen science Deep Space Network of dishes and hope to have live science data updates online on a regular basis in the next few weeks. We're mailing out a huge pile of patches and other items to ISEE-3 Reboot Project donors today.
"NASA has selected four ideas from the public for innovative uses of climate projections and Earth-observing satellite data. The agency also has announced a follow-on challenge with awards of $50,000 to build climate applications based on OpenNEX data on the Amazon cloud computing platform. Both challenges use the Open NASA Earth Exchange, or OpenNEX, a data, cloud computing, and knowledge platform where users can share modeling and analysis codes, scientific results, information and expertise to solve big data challenges in the Earth sciences. OpenNEX provides users a large collection of climate and Earth science satellite data sets, including global land surface images, vegetation conditions, climate observations and climate projections."
The Influence of Social Movements on Space Astronomy Policy, Hannah E. Harrisa, Pedro Russo
"Public engagement (PE) initiatives can lead to a long term public support of science. However most of the real impact of PE initiatives within the context of long-term science policy is not completely understood. An examination of the National Aeronautics and Space Administration's (NASA) Hubble Space Telescope, James Webb Space Telescope, and International Sun-Earth Explorer 3 reveal how large grassroots movements led by citizen scientists and space aficionados can have profound effects on public policy. We explore the role and relevance of public grassroots movements in the policy of space astronomy initiatives, present some recent cases which illustrate policy decisions involving broader interest groups, and consider new avenues of PE including crowdfunding and crowdsourcing."
