Launch history and upcoming schedule for Atlas LV-3 Agena B.
This is the canonical vehicle page for Atlas LV-3 Agena B, with launch history, upcoming missions, cadence, outcome signals, vehicle metadata, and links into the provider and exact launch records that use this rocket.
Vehicle facts are reconciled from cached public launch records and catalog metadata. External links are shown only when the upstream rocket record publishes them.
This page combines launch-feed records, launcher configuration metadata, manufacturer catalog records, and recent mission history. When upstream catalog fields are missing, the page falls back to observed launch records instead of inventing specs.
Recent launch records are grouped by orbit, mission type, payload type, crewed status, and launch site so the vehicle page answers what this rocket is actually being used for.
This vehicle page is assembled from public launch-feed rows, Launch Library 2 launcher configuration metadata, manufacturer catalog records, and recent mission history cached by T-Minus Zero.
Use this page for vehicle-level cadence, upcoming schedule, history, payload mix, and anomaly context. Exact launch records own mission timing, status, weather, pad details, streams, and source-specific updates.
The rocket page owns vehicle-level context. Provider pages own organization-level schedules, catalog pages own static vehicle metadata, and launch pages own exact launch records.


The Atlas LV-3A was a largely unsuccessful configuration until it was given an Agena B upper stage. It was responsible for the launch of Mariner II to Venus and had one of the first engines that could be restarted in orbit.

Tracks timing/status changes for up to the next 20 launches based on the last 120 days of updates.
No upcoming Atlas LV-3 Agena B launches scheduled.
