The annihilation of the antinucleus and decay of the exotic atom emit characteristic signals that can help scientists accurately identify the type of antiparticle observed.

The CSBF operates in Antarctica at approximately 78° latitude South, utilizing polar circular winds to keep balloons aloft for extended periods.

Data analysis from the GAPS experiment, optimized for detecting this antimatter component, may provide evidence of their presence, advancing the understanding of dark matter and cosmic ray properties.

Current astrophysical models predict the presence of antideutons in cosmic radiation, but they have not yet been measured due to their low intensity.

GAPS collected over half a billion events during its data acquisition period.

The GAPS mission resulted from a collaborative effort involving research institutions from the United States, Japan, Italy, and China.

The stratospheric balloon flight that hosted the GAPS experiment began above the Antarctic ice on December 19, 2025 and officially ended on January 9, 2026, at 19:42 Italian time.

Space BD's main business includes launch services supporting satellite launches and ISS utilization services for conducting space experiments.

Under the contract, ICEYE will provide data from its SAR satellite constellation to AXA DCP for near-real-time monitoring of natural disasters such as floods and hurricanes.

ICEYE signed a contract with AXA DCP on January 21, 2026, for high-precision risk monitoring using SAR satellite data.

ICEYE can also provide high-precision flood analysis by combining SAR satellite data with other information.

Blue Origin, led by Jeff Bezos, will launch AST SpaceMobile's BlueBird satellite using its New Glenn rocket in late February 2026.

Starfish Space received a contract from the U.S. Space Development Agency on January 21, 2026, for providing deorbit services to a defense-related satellite constellation in low Earth orbit.

The funding was obtained through a third-party allocation of new shares involving existing shareholder Mizuho Capital and new shareholders including Spiral Innovation Partners and Kiyo Capital Management.

Starfish Space will use its Otter spacecraft to deorbit operational satellites from the PWSA and plans to launch it in 2027.

The funds raised will be used to enhance organizational strength through hiring and training, expand launch services, and improve planning, design, and quality control functions.

The contract amount for Starfish Space is $52.5 million, making it the first dedicated mission for deorbiting LEO satellite constellations.

Space BD raised 2.4 billion yen in a Series C funding round led by Mitsubishi HC Capital on January 23, 2026.

Tomorrow.io announced a new satellite constellation called DeepSky to track activity across Earth’s atmosphere and oceans.

DeepSky is designed to provide global atmospheric monitoring in real time.

The DeepSky constellation will utilize lessons learned from the Gen1 satellite constellation for improved observations of weather and ocean patterns.

Gen1 achieved a 60-minute revisit rate with the addition of the 10th and 11th satellites in the constellation.

DeepSky represents a meaningful step toward a new category of operational intelligence as agentic AI becomes critical for planning.

BNSF Railway's CTO Matt Garland stated that modern supply chains need to continuously sense operating conditions and translate that intelligence into network-wide decisions.

Tomorrow.io's initial satellite constellation, named Gen1, has been collecting weather and ocean data from low Earth orbit since May 2023.

The DiskSat platforms demonstrated an innovative design for small spacecraft, offering greater power and capability for Very Low Earth Orbit (VLEO).

The DiskSat concept can host over 80 units in the same space where only 24 CubeSats of 6U can traditionally fit.

Each DiskSat was individually released into orbit after separating from the rocket's initial stage and clearing the payload fairing.

DiskSats are an innovative concept proposed by Aerospace Corporation that aims to maximize the usable volume within launch rockets by changing the traditional shape of satellites.

DiskSats are designed for cost-effective large constellations, with potential applications in communications and Earth observation.

Potential applications of DiskSats include global IoT networks and high-frequency monitoring for climate, agriculture, and disaster observation.

DiskSats have a thin and flat disk geometry, differing from traditional box-shaped CubeSats.

The first four DiskSats were successfully launched on December 18, 2025, aboard Rocket Lab's Electron rocket from Wallops Island, Virginia, as part of the United States Space Force's STP-S30 mission.

DiskSats orient themselves upright, rotating on their axis like a vinyl record, and are equipped with a built-in ion propulsion system for stability and maneuverability.

The ion thrusters of the DiskSats are powered by solar panels covering both sides of the disk, allowing for orbital changes and position maintenance.

The volume of each DiskSat is equivalent to 20 liters, comparable to a CubeSat 20U, with a weight of less than 3 kilograms.

The deployment sequence of the DiskSats operated as designed, and successful contact was established with all four satellites.

DiskSats can be stacked in tens within a rocket's payload volume, eliminating empty space that conventional satellites leave behind.

Each DiskSat has a cylindrical and ultra-thin structure, with a diameter of approximately 1 meter and a thickness of only 2.5 centimeters.

2025 marks the second-highest annual total of global M&A on record, with average valuations around 11.6x EV/EBITDA.

Kirk Konert, Managing Partner of AE Industrial Partners, stated that strong space companies survived and got stronger during the M&A activity peak.

The share of middle-market deals in the ALSS sector climbed from around 64 percent to about 75 percent of total transaction volume.

Average deal size in the ALSS sector dropped from just under 1 billion dollars in 2024 to roughly 375 million dollars in 2025.

In 2025, global M&A deal value is projected at about 4.8 trillion dollars, a 36 percent increase from 2024.

Air, land, sea, and space (ALSS) systems contributed significantly to the M&A rebound in 2025.

The M&A market in 2025 includes broader sectors beyond technology, such as aerospace, defense, and space.

ALSS deals in 2025 increased about 35 percent year-over-year to roughly 73 announced or completed transactions.

The proposal is considered a significant contribution to constructing a lunar base by expanding the scale of a small modular base through their connection in the early stages of lunar base development.

This proposal aims to establish space connectivity technology adapted to the space environment, building on flexible and highly constructible design techniques cultivated through research and development on the ground in Japan and Antarctica since its selection in the 3rd research proposal recruitment initiated by the exploration hub in 2017.

Specific research items necessary for establishing space connectivity technology for space use will be formulated by March 2026.
