Isar begins static fire tests of its Spectrum rocket

Isar Aerospace, one of three German rocket startups vying to the be first to complete an orbital launch, has now revealed that it has begun static fire tests of its Spectrum rocket at its launch facility at the Andoya spaceport in Norway.

In response to questioning from European Spaceflight, Isar confirmed that all components of the Spectrum rocket that will be utilized for its inaugural flight had arrived in Andøya and that testing of the first and second stages had begun.

“All components of our launch vehicle Spectrum have arrived in Andøya and the final preparations for the first test flight of Spectrum are in full swing,” an Isar Aerospace spokesperson said. “We are currently performing hot fire tests of the first and second stages. These tests will determine whether the systems meet all the necessary requirements for the first test flight.”

The company has a 20-year lease at Andoya, and though it has not announced a launch date, these ground tests suggest that launch could occur quite soon. If so, Isar will have beaten Rocket Factory Augsburg and Hyimpulse to space. Rocket Factory had apparently been in the lead until a fire during a full static fire test of its RFA-1 rocket’s first stage in August destroyed the rocket.

This race is also between the spaceports surrounding the Norwegian Sea. Rocket Factory is launching from Saxavord in the Shetland Islands, a spaceport that has been under development the longest, since before 2020, and has been plagued with the red tape problems that appear systemic in the United Kingdom. Andoya however is a latecomer in this race. Though it has been used for suborbital tests for decades, it only started its effort to become a commercial spaceport for orbital flights in November 2023, less than eleven months ago.

During an interview at a conference this week, Daniel Metzler, the CEO of the German rocket statup Isar Aerospace, imitated the kind of comments issued routinely by Elon Musk prior to one of SpaceX’s daring test launches, stating that the first launch of Isar’s Spectrum rocket will be a success “if we don’t blow up the launch site.”

“For me, the first flight will be a success if we don’t blow up the launch site,” explained Metzler. “That would probably be the thing that would set us back the most in terms of technology and time.” He went on to explain that the company’s “test early and improve iteratively” development approach was inherently risky.

Though no launch date has been set, there are indications based on the activity at the Andoya spaceport in Norway, where Isar has a 20-year lease on the only launchpad, that this launch could occur within the next month or so. Andoya received its spaceport license late last month, and it also appears that Norway’s bureaucracy is not acting to delay this activity, as has the Civil Aviation Authority in the United Kingdom.

Norway approves spaceport license for Andoya

The Norwegian government announced yesterday that the Andoya spaceport that has been used for decades for suborbital test launches, has been given a spaceport license to conduct orbital launches from the site.

According to a statement from the Norwegian ministry, the license allows the spaceport to conduct up to 30 launches a year, including four during overnight hours. Those launches, to be overseen by the Civil Aviation Authority of Norway, can take place on azimuths between 280 and 360 degrees, supporting missions primarily to polar and sun-synchronous orbits.

The German rocket startup Isar Aerospace already has a 20-year lease to conduct orbital launches from Andoya, and hopes to do the first orbital test launch of its Spectrum rocket there. According to the Norway government, the first launch is planned for this year, but that likely will only be a suborbital test, not a full orbital launch. Of the three rocket startups from Germany, Isar is the only one that has not yet done any engine tests (as far as we know) or suborbital test launches of its rocket engine or design. Hyimpulse has done a suborbital test launch from an Australian spaceport, and Rocket Factory Augsburg have done numerous tests both in Germany and at the Saxaford spaceport. This license to Andoya will likely signal the start of those public tests by Isar.

A fourth European rocket startup, PLD from Spain, is presently prepping its own launchpad in French Guiana, and hopes to conduct its own first orbital test launch next year.

Until this week it appeared that Rocket Factory was in the lead to be the first European rocket startup to attempt an orbital launch. That changed when the rocket’s first stage was destroyed during a static fire launchpad engine test earlier this week. Right now it is not clear who is in the lead.

German rocket startup signs deal with Norwegian spaceport

The German rocket startup Isar Aerospace has signed a deal to provide the Andoya spaceport in the north of Norway with a new flight tracking and safety system, to be used by all launches including Isar’s own Spectrum rocket.

The purpose of the autonomous flight tracking system is to precisely and reliably keeping track of the Spectrum launch vehicle’s position, speed and direction of travel as it ascends to orbit, which is important to guarantee Andøya Spaceport’s flight safety requirements. The objective is to further evaluate the use of the system in enabling automated flight termination functionality for launches by Andøya Spaceport’s ground system, autonomously triggering an abort of the mission if ever operational parameters of the launch vehicle are out of bounds.

This announcement today illustrates the rising competition between German rocket startups and European spaceports. Yesterday the Saxavord spaceport in Scotland and another German rocket startup, HyImpulse, announced their own launch deal. Today’s announcement is the response from Andoya and Isar.

Today’s announcement also increases the pressure in the UK’s Civil Aviation Authority (CAA) to get its regulatory act together. Andoya is positioning itself as a good alternative to the two new British spaceports in Scotland, as shown by the red dots on the map above, should red tape in the UK slow launches there.

Norway inaugurates its Andoya spaceport

Norway yesterday announced the opening its new Andoya spaceport in the far north of the country, where it hopes will become a hub for the emerging new commercial launch industry.

The location is indicated by the map to the right, in the Arctic and farther north than any other planned spaceport, making it excellent for satellites going into polar orbit.

The launch base, which eventually will have several launch pads, was built by Norwegian public company Andoya Space, on a site which until now has only been used for firing suborbital scientific experiment rockets.

Spectrum, a two-stage craft capable of carrying up to one tonne and developed by the German start-up Isar Aerospace, is scheduled to be the first rocket to be launched from island which is located near the idyllic Lofoten archipelago.

If Norway’s government works better than Great Britain’s in issuing launch permits, this spaceport will steal all business from the UK’s own two spaceports being built in Scotland.
