| 研究実績の概要 |
We are continuing to apply machine learning to problems in space research and exploration and establish deep learning computational hardware capabilities at NAOJ.
In FY2023, scientists from NASA Ames initiated bi-weekly collaboration meetings regarding orbital debris remediation, largely based on techniques from our FY2022 paper "Low-thrust rendezvous trajectory generation for multi-target active space debris removal using the RQ-Law".
We also continued to develop the computer vision based methods for lunar rover absolute localization.

2: おおむね順調に進展している
理由
The original research topic of rover localization progressed slower than planned. However, this is due to several new research directions emerging, which have been very fruitful with multiple publications and collaborations.
|
| 今後の研究の推進方策 |
For rover localization, we are exploring the use of vision transformers compared to the previous ResNet baseline. Due high interest in our work on orbital dynamics, we have pursued research collaborations in this direction. We are extending this work by scaling up the number of debris objects that can be targeted for deorbit.
|
| 次年度使用額が生じた理由 |
The original plan for the 4th year funding was to support conference and publication expenses and hardware upgrades to the GPU cluster. This did not occur in FY2023, so the remaining budget is planned to be used for these purposes for FY2024.
