For the first time ever astronomers have studied an asteroid that has entered the Solar System from interstellar space. Observations from ESO's Very Large Telescope in Chile and other observatories around the world show that this unique object was traveling through space for millions of years before its chance encounter with our star system. It appears to be a dark, reddish, highly-elongated rocky or high-metal-content object. The new results appear in the journal Nature on 20 November 2017. ...

Twice as big as Earth, the super-Earth 55 Cancri e was thought to have lava flows on its surface. The planet is so close to its star, the same side of the planet always faces the star, such that the planet has permanent day and night sides. Based on a 2016 study using data from NASA's Spitzer Space Telescope, scientists speculated that lava would flow freely in lakes on the starlit side and become hardened on the face of perpetual darkness. The lava on the dayside would reflect radiation from th...

Landing on Mars is difficult and not always successful. Well-designed advance testing helps. An ambitious NASA Mars rover mission set to launch in 2020 will rely on a special parachute to slow the spacecraft down as it enters the Martian atmosphere at over 12,000 mph (5.4 kilometers per second). Preparations for this mission have provided, for the first time, dramatic video of the parachute opening at supersonic speed. The Mars 2020 mission will seek signs of ancient Martian life by investiga...

A temperate Earth-sized planet has been discovered only 11 light-years from the Solar System by a team using ESO's unique planet-hunting HARPS instrument. The new world has the designation Ross 128 b and is now the second-closest temperate planet to be detected after Proxima b. It is also the closest planet to be discovered orbiting an inactive red dwarf star, which may increase the likelihood that this planet could potentially sustain life. Ross 128 b will be a prime target for ESO's Extremely ...

What seemed at first like a rare instance of a huge, ancient galaxy revealed itself to be an even rarer pair of extremely massive galaxies, seen on the brink of merging when the Universe was only a billion years old. This outstanding source was first identified by ESA's Herschel space observatory, and later exposed in greater detail with the ground-based Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. The earliest galaxies in the 13.8 billion-year history of our cosmos starte...

    Work Experience

    February 2010 -- present: post-doctoral research associate at the Asher Space Research Institute, Faculty of Aerospace Engineering, Technion -- Israel Institute of Technology, under the supervision of Professor Pini Gurfil.

    Mitigating the effects of zonal harmonics on the absolute and relative orbits of artificial satellites by using analytical and numerical techniques. Direct application: accurate initialization for cluster flying in order to achieve close proximity during long periods of time, without any control inputs.

    Developing a new model for numerical integration of the absolute orbits in the presence of perturbations in order to improve the accuracy and the speed of integration. Direct application: inertial orbit initialization and control.

    Developing new analytical models for station-keeping and formation-keeping. Direct application: reduced fuel consumption, lifetime extension.

    February 2004 -- January 2010: Technical University Gheorghe Asachi Iasi, Romania. Lecturer in the Department of Theoretical Mechanics.

    Besides teaching, I was carrying out research in fundamental Astrodynamics, nonlinear problems in Classical Mechanics (the Foucault Pendulum, Kepler problem in rotating reference frames, relative orbital motion), fundamental Rigid Body Kinematics (with the focus on attitude kinematics and mathematical models in robotics) and nonlinear differential equations in Applied Mathematics.

    September 1999 -- February 2004: Emil Racovita National College, Iasi, Romania. Lecturer in mathematics.
