Following the successful results of the first Deorbit Device Competition (DDC), which was held at the fourth UNISEC-Global Meeting in Bulgaria last October, we are pleased to announce that the second competition, renamed "Debris Mitigation Competition (DMC) will be held in Rome in December 2017.
We had 22 papers from 15 countries and chose 10 finalists for the 1st DDC. At the venue, there were interesting presentations from the finalists and useful exchanges between them and the reviewers. For the 2nd DMC, a target satellite will be changed from CubeSat to Micro Satellite with a weight of up to 50 kg.
UNISEC-Global is a consortium of the local chapters (UNISEC-xx) for facilitating student's practical space projects at university level, such as building and launching satellites and rockets. UNISEC-Global would like to play a useful role in improving awareness of long-term sustainability of space activities. In this respect, we will continue to discuss debris matters for finding better solutions.
The 2nd DMC will continue to identify possible innovate approaches to mitigate debris matters. All interested people, such as space engineers, researchers, students, are welcome to join and to present their ideas for discussion.

Objectives

To facilitate the sharing of innovative solutions for debris mitigation and developing effective post-mission disposal (PMD) and/or active debris removal (ADR) device that can be demonstrated and validated with a micro satellite.

Important Dates

January 27, 2017 : Call for papers
August 31, 2017 : Abstracts submission due
September 20, 2017 : Notification for acceptance

Requirements

Propose a post-mission disposal (PMD) or active debris removal (ADR) device that satisfies the following requirements:

  1. The device must be designed for the removal of a potentially non-cooperative lean satellite of 50 kg mass and maximum dimension of 1 meter. Total mass of a satellite and device can exceed 50 kg.
  2. The device will enable the satellite to re-entry within 11 years (i.e. one solar cycle) after activating. You can use any systems such as thruster, tether, membrane or electric propulsion.
  3. The device will be activated at 00:00:00 UTC, January 1, 2020 with the following orbit element:
    Semi-major axis7128 km
    Orbital inclination98.4 degree
    Eccentricity0.001
    R.A.A.N30 degree
    Argument of Perigee210 degree
    Mean Anomaly190 degree

Evaluation Criteria

The proposed deorbit device is evaluated according to the following criteria:

  1. Originality (20)
  2. Cost (20)
  3. Technical feasibility (20)
  4. Effectiveness (10)
  5. Reliability (10)
  6. Debris risk (10)
  7. Impact on/for satellite (10)
1. Originality
Has the idea not yet been realized or proposed? Is there enough originality in the idea?
2. Cost
Is it affordable for lean space missions?
3. Technical feasibility - Mechanical and electrical design
Can the idea be realized with current or emerging technology?
4. Effectiveness
How effective and how fast can the satellite re-enter?
5. Reliability
Is the idea designed to fail with a low probability?
6. Debris risk
Does the idea generate risks in producing additional debris? Will it function even if the satellite is non-cooperative?
7. Impact on/for satellite
What is the mass, volume, power and operational requirement on/for the satellite to be removed?
