India's Mangalyaan Mars Orbiter Mission (MOM), launched in November 2013 and operational until September 2022, generated substantial public discourse across social media platforms including YouTube, Twitter/X and Reddit making it one of the most socially engaged interplanetary missions in history. Systematic extraction and analysis of this discourse offer valuable insights into public perception of low-cost space exploration, national scientific pride and science communication effectiveness. This paper presents a systematic literature review of 31 peer-reviewed publications to construct a unified 32-parameter multimodal framework for analyzing public sentiment expressed on social media in the context of the Mangalyaan mission. The 32 parameters span seven analytical categories: Text Analysis (speech-to-text extraction, subtitle sentiment, keyword polarity, emotion classification, negation and sarcasm detection, comment sentiment and emoji/hashtag sentiment), Audio Analysis (tone positivity/negativity, pitch and speech rate, emotional prosody and crowd reaction), Visual Analysis (facial expression recognition, body language, mission control reactions, event detection and scene color sentiment), Metadata Analysis (title/description sentiment, engagement metrics, upload timing and trending indicators), Mission-Specific Context (orbit insertion confirmation, telemetry loss references, official statement extraction and media sentiment comparison), Temporal Analysis (pre/during/post mission sentiment, trend over time and viral velocity) and Output parameters (overall classification, multimodal score, confidence score and visualization). Findings confirm that transformer-based models achieve F1 scores above 0.90 and multimodal fusion outperforms single-modality approaches by 8–15%. Critical gaps include the absence of Mangalyaan-specific annotated datasets, limited code-mixed Hinglish sentiment capability and underdeveloped cross-platform sentiment fusion for space mission discourse.
