Abstract
The Heliophysics Environmental and Radiation Measurement Experiment Suite (HERMES) is a multi-instrument science payload that will attach to the HALO module of the Artemis Program’s Gateway lunar outpost. HERMES instrumentation includes an electron electrostatic analyzer, an ion mass spectrometer, a proton and electron telescope for energetic particles, and a set of magnetometers. After Gateway arrives in its polar lunar orbit, HERMES will conduct a science campaign that addresses objectives in heliospheric and magnetospheric physics. Analysis of the in-situ measurements from HERMES will leverage observations from other space missions. Of note are the 2 THEMIS/ARTEMIS probes already in lunar orbit. They provide measurements of particles and fields that can be compared directly with those from HERMES. With this small constellation of spacecraft it will be possible to analyze structures in the solar wind, such as CMEs and SIRs, on scales ~11 Earth radii (70,000 km). HERMES also serves as a pathfinder for future space-weather payloads as may be carried on deep-space missions of exploration for which local measurements of space-weather can contribute to accuracy of predictions and thereby contribute to crew safety. The HERMES science teams will share data and work closely with scientists from ESA’s European Radiation Sensors Array (ERSA) and with those of the joint ESA/JAXA Internal Dosimeter Array (IDA). HERMES data at all levels will be fully open and accessible through NASA's Space Physics Data Facility to enable independent analyses. In this presentation we provide an overview of science plans, including expectations for collaboration with international partners and with other science missions.

  • Pretraining has recently greatly promoted the development of natural language processing (NLP)
  • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
  • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
  • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
  • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
