Long March 8A | Unknown Payload

China Aerospace Science and Technology Corporation launches Long March 8A carrying Unknown Payload from Commercial LC-1, Wenchang Space Launch Site, People's Republic of China, China at 2026-09-11 16:00:00Z. The time is fixed to the hour and will sharpen inside T-24. The date is still provisional and can move.

  • LISTING

    Celestron Travel Scope 70 mm Refractor

    70 mm of aperture on a light tripod that packs into its own backpack, which is the whole argument for it: a scope that travels gets used. Shows lunar craters, Jupiter's four bright moons and Saturn's rings as a shape rather than a smudge. The tripod is the weak part of the package — expect to steady it.

    Beginner Dobsonians

    The category most experienced observers point a beginner at: aperture on a simple rocker mount, with no motors to fail. A starting point for browsing rather than a specific pick — compare 130 mm and 150 mm before buying.

    Beginner refractors

    Lighter and quicker to set up than a Dobsonian, weaker on faint deep-sky objects. Worth browsing if the scope has to live in a cupboard and come out on a whim.

LAUNCH CORRIDOR

FROM THIS PAD
Due east
The lowest orbit inclination a direct launch from here can reach — 19.6°, which is this pad’s own latitude. It also collects the most free speed from Earth’s rotation.
Due south
The polar and sun-synchronous corridor: 90° inclination, passing over both poles. It gets no help from Earth’s spin, which is why it costs more payload.

Drag the globe to turn it. The shading is the real terminator, and it moves.

A globe of the Earth centred on Commercial LC-1 at latitude 19.60 degrees north, longitude 110.93 degrees east. Two curved lines leave the pad. The solid gold line runs due east and marks the lowest orbital inclination a direct launch from this site can reach, 19.6 degrees, equal to the pad’s latitude of 19.6 degrees. The dashed cyan line runs due south and marks the polar corridor at 90 degrees inclination. The darkened part of the globe is the night side. Surface wind is blowing from 226°, at 14 km/h, shown as the cyan arrow at the pad.

Minimum direct inclination 20°. From 20° north of the equator, a direct ascent cannot enter an orbit inclined less than 20°, because an orbit of inclination i never passes over latitudes beyond ±i. Reaching an equatorial plane — what a geostationary transfer ultimately needs — therefore costs a plane change of 20° somewhere in the flight, while inclinations of 20° and above are available straight off the pad. The ground here is carried eastward at about 438 m/s (465 m/s at the equator, falling with the cosine of latitude), and a due-east launch keeps that head start.

The observed block is general weather for the coordinates of Commercial LC-1, not launch-commit criteria. Those are written per mission by the operator and the range, cover conditions this forecast does not carry at all (electric fields, cloud layers aloft, winds through the vehicle’s own load limits), and are published only by the operator. Wind is a common reason countdowns stop for weather — that is general context, not a rule about this flight, and no number in this block is a threshold. Nothing here is a go or no-go call, and no operator figure was published for this attempt.
