Last refreshed: Jul 17, 2026, 12:40 PM GMT+8. 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.
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.

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.

The Long March 3B / E (G2) (CZ-3B / E) is one of the most successful medium-range launchers and the strongest variant of the CZ-3 series. It was specially developed for the transport of heavy communications satellites into a geostationary transfer orbit. The additional designation "E" stands for a higher payload fairing, stretched boosters and extended fuel tanks at the first stage, over the CZ-3B.
The China Aerospace Science and Technology Corporation (CASC) is the main contractor for the Chinese space program. It is state-owned and has a number of subordinate entities which design, develop and manufacture a range of spacecraft, launch vehicles, strategic and tactical missile systems, and ground equipment. It was officially established in July 1999 as part of a Chinese government reform drive, having previously been one part of the former China Aerospace Corporation. Various incarnations of the program date back to 1956.
Payload and object details are usually published 1–2 days after launch.

A launch-area reference planning index. Use your location for a viewpoint-specific result.
A broad, sunlit jellyfish-style plume is unlikely at the launch area under the current model. The rocket may still be visible as a point.
This is a planning index, not a percent chance. Higher means the modeled viewing setup is stronger.
If needed, your browser asks permission only after you choose this. The launch-area result is not a forecast for your viewpoint.
This score uses a modeled ascent corridor rather than an exact mission path. The overall viewing setup remains useful; direction and timing are approximate.
The setup is weak right now because multiple parts of the visibility chain are underperforming.
This outlook evaluates whether a broad, sunlit ascent plume could stand out. It does not yet predict whether a specific vehicle will produce one, and an unfavorable plume outlook does not mean the rocket itself will be invisible.
