Restart has now occurred. Chamber pressures rising slightly.

And there's SECO-2. Starting now, a coast phase lasting 47 minutes and 51 seconds will last until the third burn of the second stage.

Dual-payload adaptor has separated. And we're back in a coast phase.

And we have separation of the DPAF.

We'll now take another break before the last phase of powered flight. Stay tuned.

We're about 73 minutes into the flight. Coast phase appears to be nominal thus far.

As for the Iridium-NEXT F4 mission, that's pretty much over as those satellites will have finished their deployment sequence by now.

Again, the next milestone will be the third burn of the LE-5B engine, which will last 68 seconds. That should occur in about a half-hour.

Many thanks to Zach and William for the coverage! Excellent work! I know it's still ongoing, but it's really appreciated not least because myself and Mark were holding the site together as half of LA was hitting the news site due to the Falcon 9 launch looking like a "UFO". Crazy.

Now over an hour and a half into the mission, coming up on the third burn in a little over ten minutes' time

Coverage will be resuming shortly. Five minutes until spacecraft separation - but we've got another burn before that.

Welcome back to the third and final part of tonight's coverage of the 37th H-IIA mission.

We're two minutes away from the second restart of the second stage engine, whose last burn will have a duration of 68 seconds and inject the SLATS satellite into a 450 by 643 kilometer orbit.

We should be in the third burn now, but oddly it doesn't seem to be showing on the graphic. Not sure if it isn't being covered, or if the flightplan has changed.

Second stage should have been restarted again.
