COBRA is the proposed technique to control the motion of a non-cooperative target by means of the interaction between the thruster exhaust gases from the chaser and the target object. In the original ESA SysNova study, the COBRA concept was investigated as an active debris removal system, using contactless technology to deorbit a space debris objec...

PROBA-3 will demonstrate technologies and techniques for precise Formation Flying of two spacecraft. This paper describes its Formation Flying Navigation system for relative position and velocity determination. A Coronagraph spacecraft carries fine relative position metrology and higher-thrust propulsion, and an Occulter spacecraft carries fine low...

Alexander Cropp ESA, the Netherlands, Alexander.Cropp@esa.int The COBRA IRIDES is a proposed experiment to modify the attitude motion of a non-cooperative satellite by means of the interaction between the thruster exhaust gases and the target satellite. Previously the COBRA concept was studied as an active debris removal system which relies on cont...

This paper reports the phase B mission analysis work performed for the nominal operations of the PROBA-3 formation flying mission. PROBA-3 will perform formation flying in a highly elliptical orbit, and perform Solar coronagraphy and formation maneuvering demonstrations in a 6 h region around apogee. This paper addresses the nominal orbit and the i...

This paper presents the preliminary analysis of an in-orbit demonstration opportunity to test plume impingement as a viable means to change the attitude state of a space debris based on the Prisma and Picard missions. This technique has been proposed as part of the COBRA concept studied by ESA in collaboration with GMV, Politecnico di Milano and Th...

This article describes the formation flying system of PROBA-3 as it has been developed and prototyped during phase B of the project. PROBA-3 will demonstrate the formation flying technology along with on-board autonomy for two spacecrafts in highly elliptical orbit around the Earth. After the presentation of the mission scenario, this article descr...

This paper reports the phase B mission analysis work performed for the safe orbit and the collision avoidance manoeuvres (CAM) of the PROBA-3 formation flying mission, including the recovery to nominal conditions. PROBA-3 will perform formation flying in a highly elliptical orbit, and perform solar coronagraphy and formation manoeuvring demonstrati...

Precise Formation Flying(PFF) will enable the implementation of a new dimension of future large space mission. Prior to its application, PFF needs a thorough and representative demonstration, that can only be performed by in flight application. PROBA-3 is dedicated to demonstrate such PFF. PROBA-3 will fly two small satellites in a highly elliptic...

Manned missions to asteroids are gaining momentum due to scientific, exploration and outreach reasons. Human-related constraints pose stringent requirements on the mission design. A feasibility analysis is presented for missions launching between 2020 and 2050. The system constraints are derived from on-going ESA and NASA developments, leading to t...

This presentation was part of the session : Sample Return Challenges Sixth International Planetary Probe Workshop Marco Polo is a Near-Earth Object (NEO) sample return mission currently studied by the European Space Agency (ESA). The intention is to perform this mission in collaboration with the Japanese Aerospace Exploration Agency (JAXA). It has...
