Delta IV Heavy | Demosat and 3CS-1 & 2 is a Partial Failure launch record for Boeing using Delta IV Heavy from Space Launch Complex 37B, Cape Canaveral SFS, FL, USA.
Last refreshed: Jun 14, 2023, 1:43 PM EDT. T-Minus Zero keeps this as the canonical launch record and reconciles schedule, mission, payload, media, and provider signals when those records are available.
Alternate mission URLs consolidate to this canonical launch record so exact mission timing, status, media, and source context stay on one page.
Stream links and embedded coverage.
Premium keeps the launch-by-launch change log visible so you can review slips, window edits, and status changes without waiting for an error-driven upgrade prompt.

Enhanced forecast insights (select launches).
Premium adds the higher-signal weather shell for select Eastern Range launches, including the extra launch criteria and fast-read risk rows.
Use these internal paths to move from this exact launch record into the provider, vehicle, launch-site, schedule, and mission-family pages that own broader context.
This launch currently has no dedicated mission-family hub, so provider, vehicle, site, and canonical record links are the primary internal paths.
Key structured fields for this launch record are grouped here so the page answers mission, payload, orbit, provider, source, and timing questions before the deeper tracking and media sections.
This record is preserved as historical launch context. The page emphasizes what was launched, the vehicle and pad involved, published outcome/status fields, linked programs, and source records instead of treating the mission like an upcoming countdown.

The Delta IV Heavy (Delta 9250H) is an expendable heavy-lift launch vehicle, the largest type of the Delta IV family, and is the world's second highest-capacity rocket in operation. It is manufactured by United Launch Alliance and was first launched in 2004.
Boeing as a space agency has recently provided NASA with assistance on sending humans to the ISS from American with both their construction of the CST-100 Starliner crew capsule and their work on the SLS Avionics to return to the moon and beyond. Their ventures in GPS satellite systems and Tracking and Data Relay Satellites provide information about earth-orbiting craft to stations on the ground. They also enable research on the ISS and will be helping with the construction of the Lunar Gateway.
