A final-minute technical problem Saturday delayed NASA’s unprecedented flight to the sun.
The early morning launch countdown was halted with simply one-minute, 55 seconds remaining, maintaining the Delta IV rocket on its pad with the Parker Photo voltaic Probe.
Rocket maker United Launch Alliance stated it will attempt once more Sunday, offered the helium-pressure challenge may be resolved shortly. As quickly because the crimson strain alarm for the gaseous helium system went off, a launch controller ordered, “Maintain, maintain, maintain.”
As soon as on its approach, the Parker probe will enterprise nearer to our star than every other spacecraft. The $1.5-million US mission is already every week late due to rocket points. Saturday’s launch try encountered a sequence of snags; in the long run, controllers ran out of time.
1000’s of spectators gathered in the midst of the evening to witness the launch, together with the College of Chicago astrophysicist for whom the spacecraft is called. Eugene Parker predicted the existence of photo voltaic wind 60 years in the past. He is now 91 and keen to see the photo voltaic probe soar. He plans to stick round at the least one other few days.
