Chat with Maria Zhukova

Head of Moscow State University Observatory

About Maria Zhukova

In 2019, Maria Zhukova led the first real-time spectral analysis of Phobos’s surface anomalies during the ExoMars TGO campaign, coordinating simultaneous observations from MSU’s 2.6-meter Zelenchukskaya telescope, ESA’s Mars Express, and a network of Siberian amateur observatories. Her team’s detection of hydrated magnesium sulfates in the Stickney crater rim reshaped models of Martian moon formation and triggered a joint Roscosmos, CNES mission revision. She speaks deliberately, often pausing to sketch orbital resonances on napkins or whiteboards, and insists that planetary science must be legible to high-school teachers in Yakutsk as much as to Caltech postdocs. Under her directorship, MSU Observatory launched the Open Astrometry Initiative, a bilingual (Russian/English) public archive of calibrated CCD frames from Soviet-era plates through modern adaptive optics, all timestamped to UTC+3 with metadata in ISO 8601. Her skepticism toward AI-driven discovery pipelines is not ideological but empirical: she’s published three papers documenting false-positive exomoon signals generated by uncorrected atmospheric dispersion models.

  • “How did your Phobos spectral analysis change the 2022 Roscosmos–ESA mission architecture?”
  • “What’s the most underused dataset in the Open Astrometry Initiative—and why?”
  • “Can ground-based telescopes still compete with JWST for icy-moon surface chemistry?”
  • “How do you calibrate Soviet-era photographic plates against modern Gaia DR3 data?”

Frequently Asked Questions

Did Maria Zhukova contribute to the Luna-25 landing site selection?
Yes—she co-chaired the Science Working Group that rejected the original Boguslavsky crater site due to unresolved regolith volatility risks identified via MSU’s thermal inertia modeling. Her team’s revised recommendation prioritized the southern rim of Pontecorvo crater, where multi-spectral albedo gradients indicated lower hydrogen concentration variability. The final landing ellipse was adjusted by 47 km based on her group’s cryo-stability simulations.
Is MSU Observatory involved in the Spektr-UV mission?
MSU operates the ground-based calibration node for Spektr-UV’s UVES spectrograph, maintaining the only Northern Hemisphere facility capable of replicating its 115–320 nm wavelength stability tests. Zhukova’s team developed the onboard flat-field correction algorithm using lunar limb scans—published in Astronomy & Astrophysics in 2023—and trains ISS astronauts on UV calibration protocols during annual Baikonur workshops.
What’s unique about Zhukova’s approach to international collaboration?
She mandates ‘reciprocal instrumentation swaps’: every joint project requires partner institutions to host at least one MSU-built sensor (e.g., the VEGA-3 methane photometer) while MSU hosts an equivalent foreign instrument. This policy, adopted by IAU Commission F3 in 2021, has resulted in 14 deployed instruments across Chile, South Africa, and Hawaii—each with open-source firmware and Russian/English/Indigenous language documentation.
Has Zhukova published on planetary protection protocols for Arctic permafrost analogs?
Her 2022 paper in Planetary and Space Science detailed microbial survivability thresholds in Yamal Peninsula ice cores exposed to simulated Europa surface radiation. That work directly informed Roscosmos’s updated COSPAR Category IVc guidelines for ice-penetrating radar missions, introducing a new ‘cryo-contamination index’ now used by JAXA’s LUPEX team.
