A vintage NASA spacecraft, the International Sun-Earth Explorer 3 launched in 1978, will fly by the moon on Aug. 10, 2014 after 36 years in space. The volunteer ISEE-3 Reboot Project and Google Creative Lab have teamed up to offer a live webcast



A 36-year-old NASA spacecraft will begin a new interplanetary science mission today (Aug. 10) when it makes a close pass by the moon.

The privately controlled International Sun-Earth Explorer 3 spacecraft, also called ISEE-3, will fly by the moon at 2:16 p.m. EDT (1816 GMT). You can follow the lunar flyby live in a Google Hangout beginning at 1:30 p.m. EDT (1730 GMT) on the website SpacecraftforAll.com.

The ISEE-3 spacecraft is under the control of ISEE-3 Reboot Project, a private team of engineers took control of the probe earlier this year under an agreement with NASA. The team initially hoped to move the NASA probe into a stable orbit near the Earth. But attempts failed when the team discovered that the spacecraft, which NASA launched in 1978, was out of the nitrogen pressurant needed to get the job done.

Now, ISEE-3 Reboot Project engineers are focusing their efforts on an interplanetary science mission, since at least some of the probe's 13 instruments are still working. By using a network of individual radio dishes across the world, the team will listen to the ISEE-3 spacecraft for most of its orbit around the sun.

Officials announced this week that they would collaborate with Google to offer live spacecraft data at the site SpacecraftForAll.com. Financial terms were not disclosed. Chris Lintott, of the BBC's "The Sky at Night," will moderate the Google Hangout on ISEE-3 today.

"The main feature of this is a new website developed by Google Creative Lab in collaboration with the ISEE-3 Reboot Project team that features a history of the ISEE-3 mission as well as a presentation of data currently being received from ISEE-3," co-founder Keith Cowing said in a statement.

The spacecraft was originally launched in 1978 to study the sun, and was retasked for other science missions such as looking at comets. NASA put ISEE-3 into hibernation in 1998, where it remained until the private group reactivated it this year under a Space Act Agreement.

Members raised about $160,000 through crowdfunding, most of which is gone due to the need to rent dish time at NASA's Deep Space Network to listen in, and to fly team members to the Arecibo Observatory in Puerto Rico for communications.

A few months ago, the ISEE-3 Reboot Project managed to raise $160,000 to bring the spacecraft back to Earth after 36 years roaming outer space. The team behind the campaign successfully took control of the spacecraft and reactivated some of its scientific instruments, but they found it impossible to reignite its thrusters, so it's sadly never going to make its way back home. That doesn't mean you'll never be able to see the ISEE-3 for yourself, though -- on August 10th, Google will be hosting a Hangout session to livestream the spacecraft's lunar flyby as it passes the dark side of the moon. The tech giant will broadcast from McMoon's, an abandoned McDonald's near the NASA Ames Research Center, and you can tune in through a website built for this occasion called A Spacecraft for All.

If you visit the website now, though, you'll also be able to relive ISEE-3's journey from the time it launched in 1978 through graphics made using Chrome's WebGL technology (thus, it's optimized for the browser -- we weren't even able to load it on Firefox). This website also provides access to the data gathered by the remaining onboard instruments, as well as to the spacecraft's current position and trajectory. ISEE-3, which stands for International Sun/Earth Explorer 3, was originally sent to space to measure particles, waves and plasmas. It was eventually repurposed to study the interaction between solar winds and comets until it was decommissioned. While it won't make it back to Earth, the four instruments that the Reboot Project managed to revive will be sending data through ground radio dishes for a whole year. After that, the ISEE-3 will continue its journey around the solar system and won't be this close to our planet again until 2029.
