Rocket Lab Corp (RKLB) shares kept climbing in extended trading Monday after the aerospace company announced its next Electron launch schedule, continuing what's been a strong run for the stock.

What's Happening: Rocket Lab revealed the launch window for its upcoming "Raise And Shine" mission—the first of two dedicated launches contracted with the Japan Aerospace Exploration Agency (JAXA). It'll be the company's 19th launch this year, which is a pretty solid cadence.

The mission is set to kick off from Rocket Lab Launch Complex 1 with a launch window opening December 5. The payload? JAXA's RApid Innovative payload demonstration SatellitE-4 (RAISE-4) spacecraft, because apparently space agencies love creative acronyms.

The second dedicated Electron launch for JAXA is scheduled for the first quarter of 2026. These missions represent Rocket Lab's first dedicated Electron launches contracted directly with Japan's space agency, marking a notable expansion of their partnership.
