On the day earlier than Christmas final 12 months, a Falcon 9 rocket launched from California and put two spy satellites into low-Earth orbit for the armed forces of Germany, that are collectively known as the Bundeswehr.
Initially, the mission appeared profitable. The German satellite tv for pc producer, OHB, declared that the 2 satellites had been “safely in orbit.” The addition of the 2 SARah satellites accomplished a next-generation constellation of three reconnaissance satellites, the corporate mentioned.
Nevertheless, six months later, the 2 satellites have but to turn out to be operational. In response to the German publication Der Spiegel, the antennas on the satellites can’t be unfolded. Engineers with OHB have tried to resolve the difficulty by resetting the flight software program, performing maneuvers to vibrate or shake the antennas unfastened, and extra to no avail.
Because of this, final week, German lawmakers had been knowledgeable that the 2 new satellites will most likely not go into operation as deliberate.
Saving SARah
The three-satellite constellation referred to as SARah—the SAR is a reference to the artificial aperture radar functionality of the satellites—was ordered in 2013 at a value of $800 million. The primary of the three satellites, SARah 1, launched in June 2022 on a Falcon 9 rocket. This satellite tv for pc was constructed by Airbus in southern Germany, and it has since gone into operation with none issues.
The 2 smaller satellites constructed by OHB, flying with passive artificial aperture radar reflectors, had been meant to enhance the SARah 1 satellite tv for pc, which carries an energetic phased-array radar antenna.
“The brand new SARah satellites be certain that the Bundeswehr has the potential for worldwide imaging reconnaissance unbiased of the time of day or the climate,” the German army mentioned on the time of the SARah 1 satellite tv for pc launch. “On the similar time, they supply help within the early detection and administration of crises.”
This new constellation was meant to exchange an getting older fleet of comparable, although much less succesful satellites, referred to as SAR-Lupe. This five-satellite constellation launched almost twenty years in the past.
OHB mentioned to be at fault
In response to the Der Spiegel report, the Bundeswehr says the 2 SARah satellites constructed by OHB stay the property of the German firm and would solely be turned over to the army as soon as they had been operational. Because of this, the army says OHB can be answerable for constructing two substitute satellites.
Shockingly, the German publication says that its sources indicated OHB didn’t absolutely take a look at the performance and deployment of the satellite tv for pc antennas on the bottom. This might not be confirmed.
This setback comes as OHB is making an attempt to finish a deal to go non-public—the funding agency KKR is planning to accumulate the German area firm. OHB officers mentioned they initiated the trouble to go non-public late final 12 months as a result of public markets had “structurally undervalued” the corporate.
OHB has its palms in many alternative area companies in Europe. The small launch agency Rocket Manufacturing facility Augsburg was spun out of OHB in 2018 and is working towards its debut launch later this 12 months or in 2025. The corporate can also be a provider for the bigger Ariane 6 rocket and certainly one of a number of non-public firms that’s a part of a coalition bidding to construct a Starlink-like satellite tv for pc constellation for the European Union referred to as IRIS2.
