Eris-1 | Flight Two

Gilmour Space Technologies is targeting Q1 2027 for Eris Block 1 carrying Flight Two from Eris Pad, Bowen Orbital Spaceport, Australia. Launch Library files only the first quarter, so the date is a placeholder. The date is still provisional and can move.

  • LISTING

    Celestron Travel Scope 70 mm Refractor

    A 70 mm scope on a light tripod that packs into its own backpack, so it's easy to take out. It shows craters on the Moon, Jupiter's four bright moons and the shape of Saturn's rings. The tripod is the weak part, so expect to steady it.

    Beginner refractors

    Lighter and quicker to set up than a Dobsonian, but weaker on faint galaxies and nebulae. Worth a look if the scope has to live in a cupboard.

Second test flight of Gilmour Space's orbital launch vehicle Eris.

LAUNCH CORRIDOR

FROM THIS PAD
Due east
The lowest inclination a direct launch from here can reach is 20.0°. That’s this pad’s own latitude. Flying east also gets the most free speed from Earth’s rotation.
Due south
The polar corridor, at 90° inclination, passes over both poles. It gets no help from Earth’s spin, so the same rocket can carry less.

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

A globe of the Earth centred on Eris Pad at latitude 19.96 degrees south, longitude 148.11 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, 20.0 degrees, equal to the pad’s latitude of 20.0 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. The surface wind is from 66° at 11 km/h. That's the cyan arrow at the pad.

Minimum direct inclination 20°. This pad is 20° south of the equator, so a direct launch can't reach an orbit inclined less than 20°. An orbit of inclination i never passes over latitudes beyond ±i. Getting to an equatorial orbit, which geostationary satellites need, takes a 20° plane change at some point in the flight. Inclinations of 20° and up are reachable straight off the pad. The ground here moves east at about 437 m/s with Earth's spin. That's 465 m/s at the equator, falling with the cosine of latitude. A launch due east keeps that head start.

The observed figures are general weather at the coordinates of Eris Pad. They aren’t the launch rules. The operator and the range write those for each mission, and they cover things this forecast doesn’t carry, like electric fields, cloud layers higher up and winds along the rocket’s path. Only the operator publishes them. Wind often stops a countdown, but no number here is a limit for this flight. Nothing here is a go or no-go call. No operator figure was published for this attempt.
