The promise of a picture-perfect rocket launch across Hawke Bay at the end of this week is literally up in the clouds if it's unable to get underway at first shot.
Rocket Lab has a two-week 4.43pm to 6.32pm daily window available for a southern trajectory which agents say will be a good one for viewing along the East Coast.
National weather forecasters MetService agree, if a possible nor'westerly doesn't stop a Day 1 launch taking place.

If it does intervene it could be several days before both a launch and good viewing are possible, due to a southerly front expected from the South Island.
