The proposed method first constructs a time series matrix to preserve temporal information and projects the original input into high-dimensional space using the Bi-directional Gated Recurrent Unit with Multi-Head Attention (BiGRU-MHA) encoder.

The research team led by Dr. Jeong Min Park from the Nano Materials Research Division at the Korea Institute of Materials Science (KIMS) has successfully developed a new high-performance metal 3D-printed alloy tailored for space environments.

Over the span of two projects, researchers at the University of Illinois Urbana-Champaign investigated using a propulsion concept known as multimode propulsion to get spacecraft to the Moon and developed a technique to design optimal multimode transfers. NASA provided the team with four real mission scenarios. The goal was to explore how a multimode propulsion system that integrates both a chemical high-thrust mode and an electric low-thrust mode—while using the same propellant—can succeed. They used a standard 12-unit CubeSat to accomplish four distinct missions.

Researchers at the Advanced Photon Source joined an international effort to study tiny fragments of a nearby asteroid. The specks of asteroid dust were collected from asteroid 162173 Ryugu by a Japanese space mission. The team discovered that Ryugu began its life in the outer solar system as part of a larger asteroid more than 4 billion years ago. Since breaking off from its larger parent, Ryugu slowly made its way to its current orbit within 60,000 miles of Earth.

In a new study published in the Journal of Cosmology and Astroparticle Physics, researchers have strengthened the case that matter becomes dark energy when massive stars collapse and become black holes.

A new study by an international team of researchers, including a Penn State astronomer, used NASA's James Webb Space Telescope to reveal that some of the proplyds originally detected by NASA's Hubble Space Telescope surround brown dwarfs, which are star-like objects that are too small and cool to undergo hydrogen fusion.
