Description
The COSPAR International Space Weather Action Teams (ISWAT) H4 Planetary Space Weather cluster is concerned with space weather at the planetary bodies other than Earth.With the current NASA’s emphasis on human exploration to Mars the H4 cluster’s focus will be more geared toward space weather at Mars for better scientific understanding of the environment at mars as well we for providing space weather situational awareness for astronaut safety and technology infrastructure protection. This presentation will describe the activities and status of the three new teams who will coordinate closely together:
H4-03 Mars Space Weather Community Modeling Challenge
The Mars Space Weather Community Modeling Challenge team will bring together a community of experts and models covering all Mars space weather domains. The team will work with the community in setting the challenge events and onboard event results to the Community Coordinated Modeling Center. The team will involve the broader Mars modeling community with different modeling approaches across all domains, including: Mars atmosphere and dust, magnetosphere and ionosphere, and radiation. As Mars space weather requirements become more well-defined this team will steer the modeling community to produce simulations relevant to those requirements.
H4-04 Mars Space Weather Requirements
The Mars Space Weather Requirements team will gather requirements for the safety of astronauts and robotic assets necessary for Mars exploration. Requirements are critical to guide the community toward targeted development of space weather instruments and models. The team will explore existing knowledge of hazards and risk conditions for Mars missions, covering all mission phases based on historical data from past and current robotic missions. The team will cover a wide breadth of impacts on various systems (communication, power delivery, electronics) that can occur on spacecraft, landers, and rovers related to all space weather and atmospheric conditions. Working with the modeling challenge team, this group will use simulations of specific scenarios to understand which environmental parameters are more relevant for certain impacts, in order to provide quantitative estimates.
H4-05 Mars Radiation Environment
The Mars Radiation Environment team will focus specifically on radiation dose hazards and requirements throughout all mission phases. Experience from low Earth orbit (LEO) and cis-Lunar missions will help inform hazards, however, during transit astronauts will be exposed to higher radiation doses than in LEO and for longer periods of time than for cis-Lunar missions. The team will use all available radiation data sources and modeling to characterize the radiation environment throughout a mission, and also assess nowcasting and forecasting models.
