June 13, 2019 Hyperspectral image analysis for Earth observations

Prof. Dan G. Blumberg
Vice President for Regional and Industrial Development, at Ben-Gurion University of the Negev
Hyper spectral data provide  spectral information in dozens to even hundreds of continuous narrow spectral bands. This information enables, anomaly detection, object recognition, classification and with multiple images, change detection.
Prof Dan G. Blumberg has been studying Remote Sensing for the past two and a half decades stemming from the use of synthetic aperture radar (SAR) imaging to multi-dimensional image processing for the extraction of geomorphologic information, land use, and bio-geo physical information extraction.  This presentation will provide an overview of some of the image analysis progress made.

April 25, 2019 Concurrent and Data Driven Engineering in the NewSpace Industry

Louise Lindblad
co-founder and COO of Valispace
In this talk, we will touch upon the differences between the ways of working in the traditional “Old Space” industry and the more agile methods of the NewSpace industry, a movement which is constantly lowering the barriers to entry for private companies. We’ll answer questions such as “Why are we seeing this shift in the way of working?” and “How can smaller companies stay competitive with limited budgets?”. We’ll go on to look closer at the engineering teams and how they work and collaborate. Looking at the tools we use today to build complex products, it seems like the way of working in big teams hasn’t evolved much since the 60’s. We’ll look at how, in the future, concurrent and data-driven engineering can revolutionize the way we build hardware.  

April 11, 2019 Fluid physics experiments in microgravity

Dr. Valentina Shevtsova
Head of research group and Sr. scientist at the Microgravity Research Centre of the Université Libre de Bruxelles (ULB), Belgium.
Under the weightless conditions, the programme of fluid physics experiments deals with capillary flows, diffusion, dynamics in complex fluids, heat transfer processes with phase change, physico-chemistry near or beyond the critical point, etc. Understanding how fluids work really matters, and so does measuring their properties accurately.
Three types of experiments, at which I was PI,  on-board the ISS and on parabolic flights will be discussed:  behaviour of miscible liquids under vibrations, transport properties of liquids mixtures (diffusion and Soret effect) and convection driven by capillary forces.   

March 21, 2019 Summary and Perspectives of Formation Flying for Various Space Applications

Alexander Kharlan, Skoltech PhD student
This talk is mainly about implementing various formation flying strategies in spacecraft constellations. A project currently under development by the Space Center will be discussed that suggests a formation of CubeSats with solar reflectors used to project sunlight to the ground and employing thrusters and differential drag techniques in order to control the formation. The results of a feasibility study for the project will be discussed in terms of control techniques and formation flying strategies.
Finally, some takeaways from the 2019 International Symposium on Space Flight Dynamics will be presented discussing existing and future missions featuring satellite constellations with elements of formation flying.

March 14, 2019  Preliminary Investigation Results of Scrum Methodology for Agile Development of New Space Hardware

Nicola Garzanity, Skoltech PhD student
This talk presents the preliminary results of our investigation on the effectiveness of the Scrum methodology for Agile development of New Space hardware.
The objective is to understand whether and by how much the same Scrum principles that proved successful in software can be adopted in hardware projects. We also point out the fundamental challenges of this approach for space missions.
Finally, we identify opportunities of future work for the fine tuning of Agile development methodologies in space projects and illustrate key statistics that have been collected so far.
We will also present a summary of the main takeaways of IEEE Aerospace Conference from the talks we attended and found most interesting.

February 14, 2019 Space Mission Feasibility Studies and Technology Roadmapping Using Concurrent Conceptual Design

Dominik Knoll, Skoltech PhD student
Complex engineering projects can greatly benefit from thorough design methodologies to mitigate risk and meet budget constraints.
Concurrent design is such a method used to estimate feasibility and costs in a collaborative manner at the concept stage.
This talk will present our work on concurrent design. First we will present a Concurrent Design overview and show the results of a survey among subject matter experts on how it is adopted in space agencies and industry. Then we will describe in more detail the guideline for concurrent design process and collaboration tools we developed. Finally, we will discuss the translation of this approach to the field of technology roadmapping in a corporate setting.

December 13, 2018 Tactile interaction of human with swarm of nano-quadrotors

Evgeny Tsykunov, Skoltech PhD student
We propose a novel interaction strategy for a human-swarm communication when a human operator guides a formation of quadrotors with impedance control and receives vibrotactile feedback. The presented approach takes into account the human hand velocity and changes the formation shape and dynamics accordingly using impedance interlinks simulated between quadrotors, which helps to achieve a life-like swarm behavior.
Experimental results with Crazyflie 2.0 quadrotor platform validate the proposed control algorithm. The tactile patterns representing dynamics of the swarm (extension or contraction) are proposed.
The user feels the state of the swarm at his fingertips and receives valuable information to improve the controllability of the complex life-like formation.
The user study revealed the patterns with high recognition rates. Flight experiment demonstrated the possibility to accurately navigate the formation in a cluttered environment using only tactile feedback. The proposed technology can potentially have a strong impact on the human-swarm interaction, providing a new level of intuitiveness and immersion into the swarm navigation.

November 29, 2018 Model-based conceptual design in concurrent engineering design environment for suborbital human spaceflight missions

Yaroslav Menshenin, Skoltech PhD student
Model-based conceptual design (MBCD) is the “application of Model-Based Systems Engineering (MBSE) to the exploratory research and concept stages of the generic lifecycle” (INCOSE). One of the motivations of my work is to develop and present a model-based concept framework that would enable the representation of conceptual design information for the commercial space systems. Such a framework is based on the system architecture principles (Crawley et al., 2015) and uses such conceptual modelling languages as OPM and SysML. Another motivation of the work is to demonstrate how this framework can be applied to the concept development of suborbital human spaceflight systems – such as Virgin Galactic and Blue Origin (Menshenin and Crawley, 2018).
The proposed approach enables the concurrent engineering design in early stages of the design process. In this work we will also demonstrate the utility of the Design Structure Matrix (DSM) and its applicability to solving the system architecture problems.

November 22, 2018 Iterative Closest Point with Anderson Acceleration

Artyom Pavlov, Skoltech PhD student
Iterative Closest Point (ICP) is a classical algorithm extensively used in robotics and image processing. It is a fundamental part of many Simultaneous Localization and Mapping (SLAM) setups. In this talk in addition to covering classical ICP variants, a novel modification will be presented, which utilizes modified Anderson Acceleration to improve algorithm convergence rate.

I will talk about control theory and applied mathematics problems that arise in controlling agricultural robots. Trajectories planning,  control laws synthesis, attraction domains estimation, and precise GNSS navigation will be described as well as mathematical methods involved in solution of these problems.

November 8, 2018 Satellite formation flying control approaches and algorithms

Danil Ivanov, Keldysh Applied Mathematics Institute
One of the challenges in satellite formation flying is control of the satellites’ relative motion. Of special interest are control approaches that do not require fuel consumption. Electromagnetic and aerodynamic forces, momentum exchange techniques etc. can be utilized in formations deployment and maintenance.
The talk will cover the basic principles of the well-known as well as newly-developed control algorithms. We shall discuss the implementation problems of different control strategies and consider a mission with a satellite swarm decentralized control.

October 18, 2018 Satellite attitude control systems: problems and solutions

Stepan Tkachev, Keldysh Applied Mathematics Institute
Rotational motion control and pointing capabilities are required by most satellites. Payload, antennas, solar panels usually need specific orientation is space and it the task of attitude control system to provide it.
The problem of the control laws synthesis and the approaches for the satellite dynamics study will be discussed.
There are different hardware solutions which are used nowadays. The talk will cover attitude control systems based on magnetic and gyroscopic actuators. These two types of control systems require specific algorithmic solutions because of the nature and working principles of actuators, and we will see how the mathematics that we employ makes use of or covers up the actuator-specific properties of the systems.
