NASA’s $2 billion flight to sun delayed by last-minute technical problem

A last-minute technical problem yesterday has delayed NASA’s unprecedented flight to the sun.

The early morning launch countdown was halted with just one minute, 55 seconds remaining, keeping the Delta IV rocket on its pad with the Parker Solar Probe.

NASA says a red pressure alarm for the gaseous helium system went off, prompting the launch controller to order, “Hold, hold, hold”.

Rocket maker United Launch Alliance said it would attempt the launch again today, provided the helium-pressure issue can be resolved quickly.

Once on its way, the Parker probe will venture closer to our star than any other spacecraft. The US$1.5 billion mission is already a week late because of rocket issues.

Yesterday’s launch attempt encountered a series of snags, with controllers ultimately running out of time.

Thousands of spectators gathered in the middle of the night to witness the launch, including the University of Chicago astrophysicist for whom the spacecraft is named.

Eugene Parker predicted the existence of solar wind 60 years ago. He’s now 91 and eager to see the solar probe soar. He plans to stick around at least another few days.
