SpaceX plans a Falcon 9 launch from Vandenberg Space Force Base in California for the classified U.S. Space Force mission USSF-259, with a four-hour window starting at 6 p.m. Pacific Time.

This marks the second secret U.S. Space Force mission from Vandenberg within a week, following USSF-153 launched from Space Launch Complex 4E, which used the same booster on its 27th flight.

USSF-259 is SpaceX’s second classified Space Forcemission within days, continuing a busy period of national-security launches.

Analysts note that ongoing launch activity and an expanding public float could influence stock market reactions, potentially creating volatility around the next catalyst.

At Starbase, Mechazilla hardware activity continues with catch-rehearsal work alongside preparations for later flight hardware.

The topic was discussed during Elon Musk’s surprise appearance at the All-In Summit, where timelines and safety considerations for Starship operations were updated.

Disclosures show no current positions or planned trades in the mentioned stocks within the next 72 hours.

The information source is Xinhua News Agency.

Musk said there will be no attempt to catch the Starship booster on Flight 14 due to high risk and possible debris in populated areas if a catch goes wrong.

SpaceX’s valuation signals include a GF Score of 15/100, with solid financial strength but weaker profitability, growth, value, and momentum metrics.

If Flight 14 launches within the window, it would be Starship’s first public test to place revenue-generating Starlink satellites into real orbit rather than suborbital tests.

September 22 is described as the clearest public date for Starship Flight 14, framed as Starship’s first true orbital and revenue flight using Starlink V3 satellites.
