Introduction:
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.
Objectives:
• The first outcome of this project will be a community-led paper identifying the current status and gaps in the knowledge of space weather phenomena and impacts on Mars (both in orbit and on ground) and their interplay with Martian atmospheric weather (e.g., dust storms), including a comparison with the lunar environment.
Possible outline of the paper:
1. Introduction and ISWAT H4-04 Team Goals
2. Mars Environment [in each subsection we can identify which specific environment is more relevant for which phase mission, for both humans and robots]
a. Sun – Mars Interaction [solar flux, solar wind, pickup ions, energetic particles, meteors (including Jupiter’s effect on asteroids’ orbits)]
b. Magnetosphere and Ionosphere [origin, interactions with solar wind, boundaries]
c. Atmosphere, Dust, and Terrain [includes dust from ground and meteors]
3. Space Weather at Mars
a. Review of Observations and Physical Phenomena [response of Mars system to solar events]
b. Impacts: Communications, Radiation Dose, Electrical Systems [possibly GICs?]
c. Modeling of Environment and Impacts
4. Weather at Mars
a. Review of Observations and Physical Phenomena
b. Impacts: Dust Storms
c. Interplay with Space Weather [seasonal and diurnal variations of atmospheric depth and water content affect energy thresholds for SEPs and GCRs]
d. Modeling of Environment and Impacts
5. Moon – Mars Comparison
a. Moon Environment
b. Space Weather Impacts [main differences: no magnetosphere, albedo and charging at the surface]
c. Modeling of Environment and Impacts
6. Observational and Modeling Gaps for Impact Mitigation
a. Observations
b. Modeling
c. Requirements for Human and Robotic Missions
