Final Rocket Components Arrive in Florida for Parker Solar ProbePosted on September 1, 2017 at 3:06 pm by Anna Heiney.All components of the United Launch Alliance Delta IV Heavy rocket that will launch NASA’s Parker Solar Probe have arrived for prelaunch processing at Florida’s Cape Canaveral Air Force Station.The Port Common Booster Core of the Delta IV Heavy for the Parker Solar Probe (PSP) Mission is offloaded from the Mariner and transported to the Horizontal Integration Facility. The rocket’s second stage arrived Saturday, Aug. 26, along with the third and final common booster core, which will complete the first stage. The hardware was delivered by ship to Port Canaveral, then transported by truck to the Horizontal Integration Facility at Space Launch Complex 37.The Parker Solar Probe will perform the closest-ever observations of a star when it travels through the Sun’s atmosphere, called the corona. The probe will rely on measurements and imaging to revolutionize our understanding of the corona and the Sun-Earth connection.This entry was posted in Parker Solar Probe on September 1, 2017.

Parker Solar Probe Successfully Completes Pre-Environmental Testing ReviewPosted on 10/13/2017 10:50:13NASA’s Parker Solar Probe, the first mission to fly into the Sun’s corona, has successfully completed a review that approves the beginning of the spacecraft’s environmental testing.A review panel of engineers from NASA and the Johns Hopkins Applied Physics Laboratory, where the spacecraft was designed and is being built, declared on September 29 that Parker Solar Probe has passed required performance tests and can move into environmental testing.For Parker Solar Probe, this means the probe will be subjected to a series of challenging simulations of launch and space operations that will ensure the spacecraft is up to the difficult task of exploring the extreme environment of the Sun’s atmosphere – the corona. The spacecraft will first be bolted to a vibration table at APL, which will simulate the violent physical forces of launch; Parker Solar Probe will be lifted skyward on a Delta IV-Heavy launch vehicle, the largest in the world currently in operation. The spacecraft has already completed mass properties testing, which is important for mating to the launch vehicle and for maneuvering and attitude control.In early November, the spacecraft will travel a short distance to the NASA Goddard Space Flight Center in Greenbelt, Maryland, where it will be subjected to acoustic, thermal cycling, and vacuum testing that will make sure the probe can withstand the sound generated at launch and the dramatic swings of hot and cold that it will be subjected to following launch from Cape Canaveral Air Force Station, Florida, in summer 2018.“It’s a testament to the hard work and diligence of the Parker Solar Probe team that we successfully completed our review, and we’re excited to move forward into environmental testing,” said Andy Driesman of APL, the Parker Solar Probe project manager. “We’re looking forward to completing these tests, and then heading to Florida to begin the preparations for next year’s launch.”NASA’s Parker Solar Probe spacecraft will explore the Sun’s outer atmosphere and make critical observations that will answer decades-old questions about the physics of stars. The resulting data will also improve forecasts of major eruptions on the sun and subsequent space weather events that impact life on Earth, as well as satellites and astronauts in space. The mission is named for Eugene N. Parker, whose profound insights into solar physics and processes have guided the discipline.

#TFW you get photo bombed by the #DeltaIV Heavy that will launch @ParkerSunProbe. Thanks to the @SEDSSpaceVision attendees who toured ULA's Cape Canaveral facilities in November.
Here’s a little orbital mechanics InfoG on the Parker Solar Probe’s ride to the Sun. Majestic Delta Heavy. #PSP
As those preparations continue, officials are studying problems with devices known as platinum resistance thermometers that are part of the spacecraft’s thermal control system. Those devices have suffered a higher-than-expected failure rate, according to a presentation at an April 5 meeting of NASA’s Heliophysics Advisory Committee.The thermometers are lightweight, highly sensitive temperature sensors used to help provide feedback to the spacecraft’s cooling system and solar arrays, NASA spokesman Dwayne Brown said April 9. “We put all spacecraft through a rigorous test program to make sure all systems are working as designed and it is normal for a test program to uncover issues.”“The team is looking very carefully at whether any change is needed,” Peg Luce, acting director of NASA’s heliophysics division, said at the meeting. The issue, she said, was debated “quite significantly” at a review last week to approve the shipment of the spacecraft to Florida, including whether to delay that shipment to study the problem.“There are certain, possible fixes if we need to fix something that could be done at the Cape, so the decision was to go ahead and ship,” she said.
Here's the Delta 4 Heavy just before its rollout onto the pad yesterday. This is @ParkerSunProbe's ride to space! #space @ulalaunch @torybruno
@Delta_IV_Heavy What a beautiful beast you are. Cant wait for #solarprobe! She looks great @ulalaunch @torybruno! @NASA @NASASun @NASASocial #ULA #Space #RocketScience
