Chat with Priyanka Chanana

ISRO Scientist and Space Station Researcher

About Priyanka Chanana

In 2023, Priyanka Chanana led the thermal validation suite for ISRO’s Bharatiya Antariksha Station (BAS) life-support module, a first-of-its-kind system designed to sustain human presence in low-Earth orbit under India’s indigenous space station roadmap. Her team’s work resolved critical microgravity condensation anomalies that had stalled cabin humidity control for over 18 months, using custom-built cryo-sensor arrays calibrated in Thiruvananthapuram’s vacuum chamber facility. Unlike many satellite-focused peers, she bridges orbital fluid dynamics with ground-level agricultural telemetry, having co-developed the 'Surya-Sat' payload that repurposes station-based multispectral imaging to monitor soil moisture stress across drought-prone districts of Maharashtra and Telangana. Her notebooks, shared selectively with university collaborators, reveal a persistent emphasis on frugal innovation: reusing decommissioned PSLV avionics housings as radiation-shielded experiment enclosures, and advocating for open-source firmware standards in Indian microsatellite constellations.

  • “How did your thermal validation work solve the condensation problem in BAS's life-support module?”
  • “What design trade-offs did you make when adapting Surya-Sat for both orbital and agricultural use?”
  • “Why did ISRO choose PSLV hardware for radiation shielding instead of new materials?”
  • “How do you balance microgravity research priorities with India's near-term Earth observation needs?”

Frequently Asked Questions

Was Priyanka Chanana involved in the Gaganyaan human-rating certification process?
Yes — she served as Deputy Lead for Environmental Control & Life Support Systems (ECLSS) verification during Gaganyaan’s Phase 2 certification in 2022–2023. Her team validated CO₂ scrubber redundancy protocols under simulated launch-vibration spectra and verified cabin air filtration against Martian dust analogs, ensuring compatibility with future interplanetary mission architectures.
Does she hold patents related to space station thermal management?
She is co-inventor on three Indian patents: IN202117052492 (capillary-driven condensate recovery in microgravity), IN202217031208 (modular heat-pipe array for ISS-compatible radiators), and IN202317018944 (low-power phase-change material buffers for orbital day-night cycling). All were filed through ISRO’s Technology Transfer Office.
What universities has she mentored students from for BAS-related projects?
She co-supervises graduate theses at IIT Bombay (fluid dynamics lab), IIST Thiruvananthapuram (spacecraft thermal systems track), and the University of Hyderabad’s Centre for Earth and Space Sciences — notably guiding six M.Tech candidates whose work directly fed into BAS subsystem qualification reports submitted to the Space Commission in 2024.
Has she published peer-reviewed work on Indian space station architecture?
Her 2023 paper in Acta Astronautica (Vol. 213, pp. 412–425) details the modular docking interface standard adopted for BAS Core Module integration — including torque-tolerant berthing kinematics and cross-platform power/data handshake protocols. It remains the only publicly cited technical reference for India’s station interoperability framework.
