Stats

  • This will be the 3rd launch for Rocket Lab this year.
  • This will be the 45th overall launch for Rocket Lab.

Payload info:

Rocket Lab mission page

NextSpaceflight:

This is the third of a bulk buy of three Electron launches by Synspective to deliver their StriX satellites to low Earth orbit. StriX satellites can collect data with a ground resolution of 1-3m and a swath width of more than 10-30km. Each Electron launch will deliver 1 StriX satellite into orbit.

Previous mission (On Closer Inspection) | Next mission (Live and Let Fly (NROL-123))

Watched it this morning. Are NZ launches for sun synchronous orbit always done in the middle of the night? Or is it also about the exact position as well?

And I see the next launch is from Virginia and I think will be evening in NZ! https://www.rocketlaunch.live/launch/live-and-let-fly-nro

It depends on what specific sun synchronous orbit is desired (e.g. noon/midnight orbit vs. dawn/dusk orbit), ~~and what time of year the launch occurs~~.

~~The launch time will drift by ~4 minutes earlier per day over the course of the year. If you want to launch into the same SSO 3 months later, you have to launch ~6 hours earlier in the day.~~

Edit: I was mistaken.

The sidereal day you linked to says it's about being synced with the celestial sphere (position of the stars). Not the sun?

I would have thought if you want to be in the sun, you'd need to launch to get to the same position at the same time relative to sunrise. I don't really understand how the 4 minute drift happens for solar synchronous orbits?

Upon reflection, I believe you are correct and I was mistaken. For SSO, launch time would be relative to solar time (sunrise) NOT sidereal time (stars). Whoops :)
