0631 UTC (2:31 a.m. EDT) -- Third stage power up

We are entering the final 60 minutes of our countdown to launch of the Delta IV Heavy rocket and NASA's Parker Solar Probe, a mission decades in the making to fly through the sun's outer atmosphere to obtain in-situ measurements of how the corona is heated and how the solar wind is accelerated.

The launch team has begun to power up the Northrop Grumman Star 48BV third stage. The stage provides a significant kick of additional velocity for the Parker Solar Probe on its journey into the inner solar system.

No significant issues are being addressed by the launch team, the current weather conditions are favorable and all activities are progressing smoothly for a liftoff at 3:31 a.m. EDT (0731 UTC).

The Star 48BV kick stage has been powered up, and controllers are now configuring its inertial measurement unit navigation system for flight.

This is Delta Launch Control at T-minus 21 minutes and counting. We remain on schedule, headed to the final hold at T-minus 4 minutes, for a launch this morning at 3:31 a.m. EDT (0731 UTC).

Propellant conditioning has been achieved on all 8 liquid hydrogen and liquid oxygen tanks of the Delta IV Heavy vehicle.

0657 UTC (2:57 a.m. EDT) -- Countdown holding

This is Delta Launch Control at T-minus 4 minutes and holding. The countdown has entered the planned 30-minute built-in hold designed to give a bit of margin to deal with any problems. Also during this time, the final readiness polls of the launch team and management members will be performed.

We remain on schedule for a liftoff at 3:31 a.m. EDT (0731 UTC) from Space Launch Complex 37 at Cape Canaveral. Today's launch opportunity is available for 65 minutes, extending to 4:36 a.m. EDT (0836 UTC).

0702 UTC (3:02 a.m. EDT)

Weather is observed and forecast "go" for liftoff of the Delta IV Heavy rocket from Cape Canaveral at the opening of today's launch window, the Air Force launch weather officer just reported in the countdown's final scheduled briefing.

To avoid another breach of the red line limits on the gaseous helium bottles, they have raised the limit, per NASA LSP.

The new limits are on the port and starboard booster cores. Also required some minor repairs on the TPS (that's about to get toasted by the RS-68s)

We are now in the planned 30 minute hold, T-4 minutes and holding, as our L- time continues to count down. #DeltaIVHeavy #ParkerSolarProbe

Странно, что то тема совсем не популярная среди форумчан, никого Солнце не интересует, если бы не tnt22, тема наверное потерялась уже бы уже пару лет назад.

Пуск через 20 минут, по NASA TV уже идет прямая трансляция
