Isar Aerospace Brand Guidelines: A Munich River Name, Spectrum & an Orbit From Andøya

Three engineers, a river name and a run of investors.

Isar Aerospace was founded in February 2018 by the space engineers Daniel Metzler, Josef Fleischmann and Markus Brandl, German Wikipedia says. All three had been active in WARR, the student rocketry and spaceflight group at the Technical University of Munich, which had already built its own engines and a suborbital rocket. The name comes from the Isar, the river that runs through Munich, English Wikipedia notes.

Money arrived early and kept coming. German Wikipedia says the first round, in summer 2018, brought in Vito Ventures, the venture arm of the heating maker Viessmann, the investor UVC Partners and Bulent Altan, an early SpaceX executive. Airbus Ventures and Earlybird led a later round, English Wikipedia says, followed by Lakestar, a small stake for Porsche SE in 2021 and, in 2024, the NATO Innovation Fund. The company calls itself the “first fully privately funded European solution” for launch.

It grew from about 20 staff in April 2019 to 220 by the end of 2021, German Wikipedia says, and the company now gives a figure of more than 400 people from nearly 50 nations. In December 2023 the trade paper SpaceNews named it “Startup of the Year,” according to German Wikipedia. In May 2024 it announced a new headquarters in Vaterstetten, east of Munich, with a 40,000-square-metre plant meant to build up to 40 Spectrum rockets a year; its legal notice now gives the headquarters as Vaterstetten-Parsdorf and the company name as Isar Aerospace SE. In September 2026 the company said Fleischmann had stepped down as chief technology officer to found Bavaria Instruments, and that Can Araz had taken the role; Metzler remains chief executive.

Spectrum: two stages, ten engines, liquid oxygen and propane.

The company’s one product is Spectrum, a two-stage launch vehicle for small and medium satellites and constellations. The European Space Agency describes it as 28 metres tall and 2 metres in diameter, with ten engines; Euronews reported in September 2026 that nine power the first stage and one the second. Isar Aerospace names the engine Aquila, says it burns liquid oxygen and propane, and gives a payload of up to 1,000 kilograms to low Earth orbit and 700 kilograms to sun-synchronous orbit.

Manufacturing is central to how the company presents itself. It says Spectrum is “fully designed and manufactured in-house,” that the most complex engine parts are 3D-printed from metal, and that the primary structure is a single-part carbon-composite piece made in an automated process. Those are the company’s own descriptions.

Spectrum flies from Norway. Isar Aerospace signed a 20-year lease for a pad at Andøya Spaceport in April 2021, English Wikipedia says, and Norway’s civil aviation authority granted a launch licence on 14 March 2025, according to German Wikipedia. The first flight, “Going Full Spectrum,” lifted off on 30 March 2025; about 30 seconds later the rocket fell back into the sea, Euronews reported. English Wikipedia says an investigation found that a vent valve had opened unexpectedly, leading to a loss of attitude control.

The second flight, “Onward and Upward,” lifted off from Andøya on 5 September 2026 and reached orbit. The European Space Agency called it the first launch to orbit from continental Europe; it carried six commercial and educational CubeSats and an experiment, with payloads chosen through the German Space Agency’s Microlauncher Competition at DLR, funded through ESA’s Boost! programme. ESA said the flight made Isar Aerospace the first provider to meet the orbital-launch milestone of its European Launcher Challenge, for which the company had been selected in 2025. Euronews reported that ESA’s director general, Josef Aschbacher, described the launch as historic, noting that the company had been founded only eight years earlier.

How launch companies present themselves.

Launch companies sell something few customers ever see up close, so their public image is built almost entirely from pictures and broadcasts. The familiar set is a rocket standing on its pad at dawn or under floodlights, the long-exposure streak of an ascent across a night sky, and the plume photographed from miles down the coast. Engine test stands supply a second genre: a horizontal or downward jet of fire, usually shot from a safe distance, which stands in for years of engineering that is otherwise invisible.

Factories are shown the other way round. Clean white halls, rows of tank sections, workers in coveralls and cleanroom suits suggest order and repetition rather than drama. Many launches are also accompanied by a mission patch, a small embroidered emblem in the tradition of NASA crew patches, which turns a single flight into something that can be collected and worn.

The countdown livestream has become a format in its own right, with hosts, telemetry overlays and replays of the booster or upper stage. Not every company has worked this way: in April 2016 Inverse described one maker that gave a day’s notice of its flights and published an edited highlights video afterwards, with no live webcast. Coverage now often runs alongside posts from executives on social media, which journalists quote in their reports.

The industry also meets in person. The Space Symposium in Colorado Springs and the International Astronautical Congress, which moves to a different host city each year, are where companies unveil models, sign agreements and show their identities on stands and banners. This guide looks at what can be checked about each company: who founded it, who owns it, what it has flown, and what it says about itself.

Andøya now, Nova Scotia and Kourou next.

Beyond Norway, the company is widening its list of sites. In July 2022 the French space agency CNES selected it to launch from the Guiana Space Centre in Kourou, using the pad once used by the Diamant rocket, English Wikipedia says. On 7 July 2026 it signed a 10-year agreement with Maritime Launch Services for a pad and facilities at Spaceport Nova Scotia in Canada, and its September 2026 announcement said a launch complex was under construction there. In January 2022 it won the European Innovation Council’s Horizon Prize for low-cost space launch, English Wikipedia notes.

Customers have followed. English Wikipedia lists a multiple-launch agreement with the French firm Exotrail in November 2022 and two agreements with Astroscale in 2026, the second for its ADRAS-J2 debris-removal mission. After the September flight, the company announced an agreement with the US-based SEOPS for five more launches, and said Spectrum vehicles three to seven were already in production, with the new Vaterstetten plant, which it describes as Europe’s largest integrated production facility for launch vehicles, nearing completion.

For a design guide, Isar Aerospace shows how a young launch company builds its identity around one vehicle, one remote launch site and a factory story told in its own words. Compare Rocket Factory Augsburg, another German launcher maker of 2018, and Arianespace, Europe’s established launch provider. For this guide we use a fjord-night blue, an arctic haze and a burn orange with a sans, an unofficial interpretation; no product or logo is reproduced.
