NASA's Parker Solar Probe has cleared the final procedures in the clean room before its move to the launch pad, where it will be integrated onto its launch vehicle, a United Launch Alliance Delta IV Heavy.
NASA and its mission partners are targeting Aug. 11 for the launch of the Parker Solar Probe mission to the Sun. The 45-minute launch window will open at 3:48 a.m. EDT. During final inspections following the encapsulation of the spacecraft, a small strip of foam was found inside the fairing and additional time is needed for inspection.
NASA now is targeting launch of the Parker Solar Probe no earlier than Aug. 6, 2018. Additional time was needed to evaluate the configuration of a cable clamp on the payload fairing. Teams have modified the configuration and encapsulation operations have continued. Teams also have successfully repaired a leak in the purge ground support tubing on the third stage rocket motor, which was discovered during final spacecraft processing late last week. The satellite will launch on a United Launch Alliance Delta IV Heavy rocket from Space Launch Complex 37 on Cape Canaveral Air Force Station in Florida.
Teams require additional time for processing NASA's Parker Solar Probe spacecraft after discovering a minor tubing leak in the ground support equipment during final processing. The tubing is being repaired, and the spacecraft is healthy. As always, operations take precedence during launch and we needed to cancel media day activities on July 13, 2018. NASA will make every effort to provide updated imagery of the spacecraft prior to encapsulation.
NASA and the Johns Hopkins University Applied Physics Laboratory are now targeting launch of the agency's Parker Solar Probe spacecraft no earlier than Aug. 4, 2018. Originally scheduled to launch on July 31, additional time is needed to accommodate further software testing of spacecraft systems. The Parker Solar Probe will launch on a United Launch Alliance Delta IV Heavy rocket from Space Launch Complex 37 on Cape Canaveral Air Force Station in Florida.
NASA's Parker Solar Probe depends on the Sun, not just as an object of scientific investigation, but also for the power that drives its instruments and systems. On Thursday, May 31, 2018, the spacecraft's solar arrays were installed and tested. These arrays will power all of the spacecraft's systems, including the suites of scientific instruments …
Throughout its seven-year mission, NASA’s Parker Solar Probe will swoop through the Sun’s atmosphere 24 times, getting closer to our star than any spacecraft has gone before. The spacecraft will carry more than scientific instruments on this historic journey — it will also hold more than 1.1 million names submitted by the public to go to the Sun.
NASA's Parker Solar Probe gets its power from the Sun, so the solar arrays that collect energy from our star need to be in perfect working order. This month, members of the mission team tested the arrays at Astrotech Space Operations in Titusville, Florida, to ensure the system performs as designed and provides power to the spacecraft during its historic mission to the Sun.
You don't get to swim in the Sun's atmosphere unless you can prove you belong there. And Parker Solar Probe's Faraday cup, a key sensor on the spacecraft, earned its stripes on April 19 by enduring testing in a homemade contraption designed to simulate the Sun.
NASA's Parker Solar Probe will carry 1,137,202 submitted and confirmed names on its journey to the Sun. Submissions opened on March 6, 2018, and closed on April 27 at 11:59 p.m. EDT. A chip containing the names will be installed onto the spacecraft before launch.
