Eight startups have established partnership agreements with South Soma City.

South Soma City has partnered with major corporations like Mitsubishi Logistics and research institutions like Tohoku University.

The first test launch of AstroX's mini hybrid rocket in South Soma City took place on August 25, 2024, with approximately 150 spectators attending.

The 'Fukushima Innovation Coast Concept' is being implemented in Fukushima Prefecture, which includes South Soma City, aimed at recovery after the Great East Japan Earthquake.

The area offers subsidies for reconstruction efforts, which is a significant factor for startups choosing to establish themselves in South Soma City.

Several companies, primarily space startups, have set up bases in South Soma City, enhancing its presence as one of Japan's hubs for the space industry.

The South Soma Robotics Industry Council supports the creation of a supply chain for the space industry, having established the South Soma Aerospace Industry Research Association.

CesiumAstro is a supplier to Rocket Lab for its Space Development Agency contract.

This financing represents the largest instance of funding under the Make More in America Initiative.

CesiumAstro develops systems including multi-beam active phased array payloads and components such as software-defined radios.

The financing package includes a $185 million EXIM-authorized debt facility and a $15 million revolving credit facility from J.P. Morgan.

CesiumAstro secured $200 million in financing from the Export-Import Bank of the United States (EXIM) to expand its manufacturing capability in Texas.

CesiumAstro plans to acquire a 270,000-square-foot facility in West Austin for space and defense communications manufacturing.

The financing was approved under EXIM’s Make More in America Initiative (MMIA), aimed at boosting U.S. manufacturing and securing supply chains.

CesiumAstro plans to more than double its Texas workforce by 2030, adding more than 500 high-skill jobs.

The second Spectrum flight will be the first to carry payloads as part of Isar Aerospace's involvement with the DLR Microlauncher Challenge.

On 13 January, Andøya Space published a NOTMAR revealing 15-minute launch windows from 20 to 23 January between 21:05 and 21:20 CET.

The German aerospace agency DLR launched the Microlauncher Challenge in May 2020 to foster the development of sovereign launch capabilities, funded through ESA’s Boost! programme.

Isar Aerospace is working on Spectrum rockets for flights three through seven, indicating plans to rapidly ramp up its launch cadence.

Payloads from the DLR Responsive Space Competence Center and the ZfT – Center for Telematics are no longer listed for Spectrum's debut flight.

Remaining payloads for Spectrum's debut flight include those from the Technical University Berlin, University of Maribor, and the Norwegian University of Science and Technology.

The funding for Isar Aerospace came with the requirement to launch two sets of payloads with a combined mass of no more than 150 kilograms each over its first two flights.

In December 2021, Isar Aerospace announced that seven payloads had been selected to fly aboard Spectrum’s debut flight.

Isar Aerospace opted not to carry the first set of payloads aboard the inaugural flight of Spectrum.

The updated manifest for Spectrum's debut flight includes new payloads from EnduroSat, the TU Wien Space Team, and Dcubed.

The payload manifest for Spectrum's debut flight has been adjusted since its initial selection.

Isar Aerospace launched its first Spectrum rocket in March 2025 from the Andøya Spaceport in Norway, but it failed less than a minute into flight.

In December 2025, Isar Aerospace announced successful hot fire tests of both stages of the Spectrum rocket for its second flight.

Isar Aerospace is preparing for the second flight of its two-stage Spectrum rocket, with launch opportunities from 21 to 23 January.

In May 2021, Isar Aerospace was announced as one of two second-round winners of the challenge, securing €11 million in funding.

Isar Aerospace's second flight of the Spectrum rocket is dubbed 'Onward and Upward' and is scheduled to occur no earlier than 21 January.

On 12 January, Andøya Space published a temporary road closure notice for the flight from 12 to 23 January.

The phenomenon of 'return to RM' refers to a brief variation in RM consistent with a dense, magnetized plasma passing through the line of sight.

The discovery supports a recent unified physical framework proposed by Professor Bing Zhang and his collaborator, suggesting all FRBs originate from magnetars with interactions in binary systems allowing preferred geometries for more frequent explosive events.

The RM increased by over one hundred times and then rapidly decreased over two weeks, returning to the previous level.

A natural explanation for this is that a nearby companion star expelled the plasma.

The discovery indicates that FRBs are part of a binary stellar system rather than isolated stars.

The companion star cannot be directly observed at this distance, but its presence was revealed through continuous radio observations with FAST and the Parkes telescope.

An international team of astronomers, including researchers from the Department of Physics at the University of Hong Kong, discovered that some sources of fast radio bursts (FRBs) reside in binary star systems.

The repeating sources have been monitored by FAST since 2020 through a dedicated FRB scientific program co-led by Professor Bing Zhang.

FRB 220529A is one of the actively repeating FRBs monitored continuously with FAST.

The discovery was published in Science and was based on nearly 20 months of monitoring an active and repeating FRB located about 2.5 billion light-years away.

After a long-term observation lasting 17 months, a significant increase in RM was detected in late 2023.

This discovery was made possible by constant observations with the world’s best telescopes and the hard work of the research team.

The evidence strongly supports the existence of a binary system containing a magnetar and a star similar to our sun.

Long-term continuous monitoring of repeating FRBs could reveal how common binary systems are among these mysterious sources.

Changes in the polarization properties of radio waves can reveal the environment surrounding an FRB source.

The team used the Five-hundred-meter Aperture Spherical Telescope (FAST) in Guizhou, known as 'China Sky Eye', to detect a signal revealing the presence of a nearby companion star orbiting the FRB source.

The required densification of plasma aligns with coronal mass ejections emitted by the Sun and other stars in the Milky Way.

Professor Bing Zhang is a professor of astrophysics at the Department of Physics and the founding director of the Hong Kong Institute for Astronomy and Astrophysics at HKU.
