Mission Description	IMAP (Interstellar Mapping and Acceleration Probe) is a NASA mission to study interactions between solar wind and the local interstellar medium. Carrying a suite of 10 scientific instruments, IMAP is able to investigate how particles are accelerated, determine their composition, as well as help to advance space weather forecasting models. The IMAP launch also includes the space weather satellite SWFO-L1 (Space Weather Follow-On – L1) for NOAA and the GLIDE (Global Lyman-alpha Imagers of the Dynamic Exosphere/Carruthers Geocorona Observatory) mission to study far ultraviolet emission in the Earth’s exosphere.

As of 6:44 PM Tuesday September 23, 2025. Launch times are subject to change or cancellation at any time. Consult SpaceX.com for more information.

Next Space Flight an app for iOS and Android phones, has a real-time countdown clock that is accurate to a second, give or take. The app is free. Search the App Store or Google Play. They are also on the web: nextspaceflight.com.

Launch Viewing: In Person

The best free options are available for spectators: Northern Titusville parks on Washington Avenue / US-1, For example, Space View Park, Sands Park, Rotary Riverfront Park.

Playalinda Beach will be open, but call ahead and go early. Playalinda Beach generally opens at 6 AM ET this time of year, and that is only 90 minutes before liftoff. Call ahead if you are planning to go: 386-428-3384.

Remember that there is a delay between a launch stream and the actual countdown clock. That is simply because of physics: it takes time for the signal to travel from the launch site, through the Internet, and back down to your phone, resulting in a five to fifteen-second delay.
