Original analysis of NASA Voyager 1 spacecraft data, including magnetometer readings, plasma wave spectrograms, electron density extraction, and 3D trajectory visualization. All data sourced from NASA JPL and SPDF archives.
Curated facts about Voyager 1 — from the 1 light-day milestone to the Golden Record, engineering marvels, and scientific firsts.
3D visualization of Voyager 1's complete outbound trajectory from 1977 launch through planetary encounters (Jupiter 1979, Saturn 1980) to current interstellar position beyond 160 AU.
Advanced spectrograms of Voyager 1's Plasma Wave Subsystem (PWS) data, revealing properties of the interstellar medium through frequency analysis and wave classification.
NASA-style electron density extraction from plasma frequency ridges, providing measurements of the interstellar medium density surrounding Voyager 1.
Interactive dashboard showcasing Voyager 1 magnetic field data from NASA SPDF archives. Features dynamic plotting, statistical analysis, and time-series visualizations.
Research on 3I/ATLAS, a confirmed interstellar object entering our solar system. Analysis covers orbital mechanics, JWST volatile detection signatures, and brightness/trajectory modeling.
Orbital elements, ephemeris data, MAST catalog cross-references, and observational analysis of the third confirmed interstellar object.
A scientific hypothesis exploring whether our universe could exist within a black hole, grounded in General Relativity and foundational black hole physics. Covers Pathria (1972) to Gaztañaga (2025).
Topics: spin-torsion cosmology, quantum degeneracy pressure, Schwarzschild radius calculations, bouncing cosmology models, and observational predictions.
A school paper written by Prabhu Sadasivam in 1993 exploring a hypothetical mission to Mars, including robotic exploration concepts. Represents an early expression of scientific curiosity that connects to the current deep space research program.
Original scanned document with edited transcript, author reflections on exploration, time horizons, and leadership.
