Space Education and Research Foundation organized its
21st webinar. The topic of this webinar was “Remote Sensing
of Planets”. It had four talks by Dr. Megha U. Bhatt
(Planetary Science Division, Physical Research Laboratory, Ahmedabad, INDIA).
These talks were made live one each on 8th, 9th, 10th
and 13th January 2020.
About the speaker (Dr. Megha Bhatt)
Dr. Megha Bhatt is presently
a faculty at Planetary Sciences Division of Physical Research Laboratory,
Ahmedabad. She obtained her B. Sc. and M. Sc. degree from Rani Durgavati Vishwavidyala,
Jabalpur. She completed her PhD in 2012 from Max Plank Institute for Solar
System Research, Germany. She developed a new iron estimation algorithm using
the multispectral dataset acquired by the InfraRed Spectrometer-2 (SIR-2)
onboard Chandrayaan-1 mission as a part of her PhD work. Her research is
focused on understanding the evolution of our solar system by studying the
surface composition of airless bodies. In particular, her interest lies in
mapping the major lunar elements and mineral exposures at the top-most layer of
the Moon surface which provides insights on the mechanisms that governed the
formation of the Moon and its subsequent internal differentiation. Her major interest is in the spectrometric
observations in the Visible-Near infrared (VIS-NIR) wavelength range.
Summary
of the talks of the webinar on “Remote Sensing of Planets”
Talk 1: Comparative Planetology
Understanding of Earth and its
relationship to the other planets of solar system have been significantly
improved during last fifty years. All planetary bodies of our solar system have
been visited by spacecraft for a better understanding of each individual
planet. This talk discusses the diverse worlds of our solar system with main
emphasis on understanding crustal evolution in terrestrial planets.
Talk 2: Reflectance spectroscopy
Reflectance spectroscopy is the
study of light that has been reflected or emitted by materials. The reflectance
spectrum carries the information about the mineralogical composition of the
surface area. However, many other factors, like the grain size distribution, the
viewing geometry, and space weathering affect the reflectance spectrum
resulting increasing complexities in mineral detection. After describing
laboratory based reflectance spectra, challenges and limitations of reflectance
spectroscopy will be discussed in detail.
Talk 3: Remote sensing of Moon
The integrated approach of
exploring the Moon through analysis of the returned samples, Earth-based
telescope and orbital data sets has provided in-depth knowledge not only about
the Moon origin and evolution but also about the solar system evolution. This
talk focuses on the important results obtained through previous and ongoing
missions to the Moon.
Talk 4: Advances in Planetary
Sciences
New planetary missions equipped
with latest instrumentations pouring new information about individual bodies of
our planetary system. Important results from recent missions; Messenger, Mars
Reconnaissance Orbiter, Mars Orbiter Mission, Venus Express, Hayabusa, Rosetta,
New Horizons, and New Horizons will be discussed. The discussion will be
focused on the outstanding open questions in the field that can be further
studied in detail using upcoming planetary missions.
