Interview for Stardust Podcast.

Sai Abhishek Peddakotla was born on the 22nd of May, 1995 in a traditional weaver's family in Yadiki, a small village in the state of Andhra Pradesh and raised in the several areas of Andhra Pradesh throughout his schooling in India. He is a firm believer in “the law of attraction” and derives his motivation from the curiosity and boundless possibilities in space flight. His hobbies and interests include listening to classical guitar and piano music, an avid aficionado of Japanese anime, football, pencil sketching and a fountain pen enthusiast.

He obtained a bachelor's degree in Aerospace Engineering (2012-2016) from Amrita Vishwa Vidyapeetham, Coimbatore, India with a distinction. He obtained a master's degree in Aerospace Engineering specialised in aerodynamics (2016-2018) from the IITK, India where he also earned an Academic Excellence Award for his performance. Majority of his time at IITK during master's degree was oriented towards studying and understanding several particle-based simulation techniques like DSMC and MD under the guidance of Prof. Rakesh Kumar at the Non-equilibrium Flow Simulation Laboratory (NFSL). Before joining his current position, he worked as a “Project Engineer” during 2018-2019 at the Indian Institute of Technology Kanpur (IITK), India with Prof. Rakesh Kumar on several phenomena related to rarefied, re-entry physics from a particle-based computational framework.
Sai Abhishek Peddakotla is currently a Marie Skłodowska-Curie Early Stage Researcher in the Stardust-R project and a PhD candidate at the University of Strathclyde, Glasgow, UK. His work focusses on the development and implementation of uncertainty based multi-fidelity approaches for the effective and efficient prediction of the demise of space objects during re-entry. Particular emphasis will be given to understand the relevant fragmentation process under the re-entry aero-thermal environment.

ESR2's Project

This work relates to the development of methods and tools for the design and uncertainty quantification of space objects that are due to completely demise during re-entry. The work associated to this post will investigate both the physics of the re-entry process, including possible fragmentations, and the required computational tools to estimate the footprint of the fragments and the probability of a ground impact.

ESR9 Modelling and simulation of small asteroid populations 
Marco Fenucci (
University of Belgrade)

Marco Fenucci was born in San Miniato, a small village between Pisa and Firenze. He graduated in Mathematics at the University of Pisa in October 2016. In November 2016, he joined the Ph.D in Mathematics in the same university, under the supervision of Prof. Giovanni Federico Gronchi. In October 2018 he visited the University of Barcelona for a period of four months, collaborating with Prof. Ángel Jorba.

In the summer 2019 he was elected as an ESR in the Stardust-R Project at the Faculty of Mathematics of the University of Belgrade. His work will focus on the dynamics and the criticality of small asteroids.

In his spare time he likes running, hiking and reading.

ESR9's Project

Our current knowledge of the orbital and size distribution of a very small asteroids, down to few tens of meters in size may not be fully appropriate. Some available estimations are based only on indirect evidence, such as disruption rate of main belt asteroids. The asteroid belt is also subject to evolutionary processes, but so far, no model has included all the important processes affecting asteroid evolution. Besides, new models still have to be successfully tested against known constraints.

The project will be aiming to better understand the orbital and size distribution of small asteroids, below 100 meters in size. To achieve project's goals the ESR should study dynamical and collisional evolution of asteroids in this size range, combine this in a single self-consistent model, and test the model against all available constraints.

In addition, the ESR will work on characterization of near Earth asteroids and should define a criticality index that provides a measure of how easy the asteroid is to deflect with a given deflection method, and how interesting the asteroid is to explore and to exploit.

ESR12 Advanced Machine Learning and Computational techniques for Space Traffic Management
Emma Stevenson (Universidad Politécnica de Madrid, Spain)

Emma Stevenson is a Stardust-R Early Stage Researcher based in the AI+DA (Applied Intelligence and Data Analytics) department at the Universidad Politécnica de Madrid. She is researching how advanced machine learning and artificial intelligence techniques can be applied to automating the decision processes involved in collision avoidance for space debris.

Emma worked for ESA´s Space Debris Office (SDO) at the European Space Operations Centre (ESOC) in Darmstadt, Germany, as a Young Graduate Trainee for the last two years, and will now be continuing her research into the sustainable use of space. During this time, she worked on orbit determination and catalogue unification, as well as re-entry analysis, space debris environment evolution models and other activities carried out by the SDO. It was her involvement in the development of ESA´s machine learning competition for predicting whether a satellite should perform a collision avoidance manoeuvre, that motivated her to further her research in this area within the Stardust-R programme.

Originally, her background is in Physics, specialising in astrophysics and modelling with a Master´s thesis in gravitational wave detection from supermassive black hole binary systems from the University of Birmingham. During her degree, she carried out an internship at the UK Meteorological Office in software engineering for long-term climate models.

The main objectives of this project are:

● To develop machine learning techniques to predict collisions, sequences of close encounters and plan collision avoidance manoeuvres.

● To develop methodologies to estimate the risk of the execution of collision avoidance manoeuvres by fusing simulated and historical scenarios.

● To develop methods to fuse multiple sources of information, with different levels of fidelity and reliability.

● To apply these methodologies to support ground operators.

● To develop visualisation and simulation environments to assess the performance of these methods.
