Spectrum | AT-Astra and Others (Spectrum Flight 3)
Isar Aerospace launches Spectrum carrying AT-Astra and Others (Spectrum Flight 3) from Orbital Launch Pad, Andøya Spaceport, Norway on November 26, 2026 at about 20:00 UTC. Launch Library files that time to the hour, so it can be out by up to an hour. 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 Dobsonians
A big mirror on a simple rocker mount, with no motors to go wrong. This is a search, not one pick. Compare 130 mm and 150 mm models before you buy.

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.

MISSION BRIEF
Third test flight of the Isar Spectrum launch vehicle. This launch will carry various satellites including R-Space’s AT-Astra/IOD-01, which will perform in-orbit demonstrations for ENPULSION, SUNBOOSTER GmbH, and Synopsis Planet.

LAUNCH CORRIDOR
- Due east
- The lowest inclination a direct launch from here can reach is 69.1°. 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 Orbital Launch Pad at latitude 69.11 degrees north, longitude 15.59 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, 69.1 degrees, equal to the pad’s latitude of 69.1 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 159° at 8 km/h. That's the cyan arrow at the pad.
LAUNCH SITE
Orbital Launch Pad
Andøya Spaceport, Norway
OBSERVED 2026-11-11 10:00:00Z // OPEN-METEO (CC BY 4.0) // GENERAL CONDITIONS, NOT LAUNCH CRITERIA
Minimum direct inclination 69°. This pad is 69° north of the equator, so a direct launch can't reach an orbit inclined less than 69°. An orbit of inclination i never passes over latitudes beyond ±i. Getting to an equatorial orbit, which geostationary satellites need, takes a 69° plane change at some point in the flight. Inclinations of 69° and up are reachable straight off the pad. The ground here moves east at about 166 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 Orbital Launch 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.
