Group 1
Space laser communications

Moderator: Alberto Carrasco-Casado, Space Communications Laboratory, National Institute of Information and Communications Technology (NICT)
Assistant: Ryo Suzumoto, the University of Tokyo

Introductionintroduction pdf / Final presentationfinal presentation pdf

Space laser communication holds the promise of revolutionizing the amount of data spacecraft can transmit by multiplying the data rate by several orders of magnitude while reducing the size, weight and power of the communication payloads. This technology has been studied for several decades, but its applications in real scenarios in space have started appearing only recently. The goal of this discussion group is to analyze the different scenarios in which space laser communications can be used, the new applications that will be enabled, the role of small satellites, and the impact it can bring to future spacecraft.

Group 2
CubeSat Interface

Moderator: Marloun Sejera, Kyushu Institute of Technology
Assistant: Makiko Kishimoto, Kyushu Institute of Technology

Introductionintroduction pdf / Final presentationfinal presentation pdf

There are various CubeSat component vendors available worldwide. The electrical interfaces from different vendors are often not compatible, even if they follow PC-104 specification. The incompatibility leads to additional time in the satellite development, assembly and integration. It may even require an interface board or harness to absorb the difference, adding extra complexity to the system. Clear definition of electrical interface, such as the connector type and pin assignment help shortening the satellite delivery time.
As CubeSat development and utilization proliferate worldwide, international standards to promote the CubeSat sectors are desired. A new project to standardize the CubeSat electrical interface has been started in summer 2019. The aim of this group discussion is to share the experience of interface compatibility and incompatibility from CubeSat developers' point of view, discuss about the benefits and harms of the standards, share the ideas about improving the interface architecture, discuss the scope of standard and others. Everybody who is interested in CubeSat interface is welcome.

Group 3
Deep Space Exploration Mission with CubeSats

Moderator: Masahiro Fujiwara, The University of Tokyo
Assistant: Yukiya Ozeki, Shizuoka University

Introductionintroduction pdf / Final presentationfinal presentation pdf

Deep space formation flying and constellation are becoming realistic mission architectures because of the advancement of technologies for interplanetary CubeSats. In asteroid explorations, some missions have been already proposed. For example, in ESA's Hera mission for an investigation of a binary asteroid, two 6U CubeSats will be brought as secondary payloads by a mother spacecraft and perform some missions which will be complementary to mother spacecraft's missions. CubeSats as secondary payloads have greater agility and higher risk tolerance than a mother spacecraft. Therefore, such architectures might achieve advanced missions that only conventional monolithic spacecraft cannot do.
In this group, we will discuss how interplanetary CubeSats are utilized to enhance the scientific outcome of the mission and to achieve new advanced missions.

Group 4
Business Development of HEPTA-Sat Program

Moderator: Masahiko Yamazaki, Nihon University and Michael Siddall, the University of South Australia
Assistant: Haruki Momose, Nihon University

The HEPTA-Sat training program has been offering an opportunity to learn satellite technology to more than 400 people worldwide. To meet increasing needs and spread the training program in a sustainable way, business viewpoints should be taken into consideration.

The purpose of this session is to design a sustainable business framework and to work with potential partners and collaborators.

The session will be organized as follows:

  1. Self Introduction 10 minutes
  2. Presentation on HEPTA-Sat business plan 20 minutes
  3. Discussion on how to sustain and develop HETPA-Sat training
    (forming several groups consisting of 3-4 people) 1 hour
  4. Identifying action items for the coming 2 days towards the finalpresentation on December 3rd and making one-year plan. 30 minutes

Keywords: HEPTA-Sat, capacity building, self-learning, satellite, training, sustainability, business plan

Group 5
Global University Space Debris Observation Network (GUSDON)

Moderator: Fabio Santoni, Sapienza University of Rome
Assistant: Hiroto Seki, the University of Tokyo

Introductionintroduction pdf / Final presentationfinal presentation pdf

GUSDON (Global University Space Debris Observation Network) is the proposal for gathering university together and share or gain experience in space debris optical observation.
The risks related to the space debris are very well known, including re-entering objects and in-orbit collisions. It is therefore very important to monitor the space debris environment through appropriate observation systems.
Space Debris can be monitored with several techniques, but optical observations perfectly fit within the schedules, the budget and the degree courses timelines of Universities. Indeed, high quality data can be acquired with low cost hardware. The observatories can be operated by students and untrained personnel without any risks of hurting or disturbing with the operations, in contrast with active systems, such as radars or laser ranging infrastructures.
The discussion will focus mainly on (but not limited to):

  • education, for the chances of having a huge educational return at all levels, from students to professors;
  • science, since the distribution of observatories in all countries will help improving space debris monitoring and related techniques
  • awareness for a larger public, for the potential stimulation of awareness on the space debris problem

Group 6
International collaboration proposal

Moderator: Nicolas Martinod, EPFL
Assistant: Hirotaka Kondo, the University of Tokyo

Introductionintroduction pdf / Final presentationfinal presentation pdf

Nowadays CubeSat missions from Universities are flourishing. The standardization and the numerous suppliers of CubeSat subsystems allow for fast implantation and low-cost space missions. However, the collaboration, between CubeSat teams on an international level, is fairly weak. Yet, we are all working on similar topics facing similar issues in our mission development. Sharing our experience about system engineering, mission design, suppliers, technical studies, launch, and many others, would facilitate the implementation of CubeSat missions and pave the way for the next ones. It will greatly help in making space science and technologies available for every country.
This discussion is about how we could set such collaboration and sharing of information to create a synergy that will beneficiate us all.

Moderator: Mac Kanazawa, Space BD, Inc. and Hilde Stenuit, Space Applications Services
Assistant: Shuhei Matsushita, the University of Tokyo

Introductionintroduction pdf / Final presentationfinal presentation pdf

Explanation: The budget of the ISS operation after 2025 is still unclear among the participating governments. NASA and other national space agencies are considering re-directing their budgets to deep space exploration such as Gateway. In amidst of this transition, there is a high potential for further commercialization of the ISS in order to keep it sustainable. What kind of uses or services can be envisaged making use of the unique space assets one can find on ISS? You can come up with any creative ideas utilizing external and/or internal platforms on ISS, and/or any cost reduction plan.

Format: Case study - the group members do ideation, discuss the business plan and make a presentation about their ideas to commercialize the ISS post-2025

Target: Anyone who have the unique and ambitious mind for private-sector-driven space development, especially in the area of LEO.

Group 9
Global Space Job Fair

Moderator: Bernd Weiss, SpaceJobFair
Assistant: Morito Katsuyama, the University of Tokyo

Introductionintroduction pdf / Final presentationfinal presentation pdf

Background: Remember your feeling when you started dreaming about getting a job in space? Working on missions to Moon, Mars, or build technology enhancing people's lives on Earth? Like yourself, people all over the world search for career opportunities and would like to work in space. But, while the space economy and the demand for talent are growing, gaps do exist; not enough internships, entry-level opportunities are rare, and intransparent search mechanisms make it hard for companies to identify candidates. SpaceJobFair launched in 2015 to tackle them, bridging the gap between hiring companies and highly-skilled candidates. The concept: attract, inspire, support! Attract the best students, graduates, and professionals; inspire them to launch a career in space; support them to learn missing skills or with access to the global space industry. UNISEC-Global took over the lead for Japan and is organising the first SpaceJobFair in Tokyo.

Group Result: The goal of this Group discussion is to look into both organisations and their strengths to derive ideas for future career events and determine their overall value. The goal is to provide leadership with information in support of deciding about expanding a collaboration, potential locations for similar events, and value-added services, eventually leading to a Global Space Job Fair framework.

Audience: If you want to share your passion for space and like the idea of helping others to get job in space, this group can be for you. And you might be organising a SpaceJobFair in your region soon.
