Project Icarus (interstellar)

Project Icarus is a theoretical engineering design study aimed at designing a credible, mainly Icarus Interstellar. It was motivated by the British Interplanetary Society's Project Daedalus, a similar study that was conducted between 1973 and 1978 by the BIS.[2]

The project is planned to take around five years and began formally on September 30, 2009.[3] An international team of dozens of scientists and engineers has been assembled. The Icarus Interstallar project web site reveals the evolving team.

The Project Team, a world wide group made up of volunteers who are members of Icarus Interstellar and the British Interplanetary Society, has some notable members such as:

In September 2011 Project Icarus received a mention in the BBC's Sky at Night Programme.[9]

Members of the Project Icarus study group went on to form a Icarus Interstellar, which then launched various other projects other than just Project Icarus. Icarus Interstellar has the mission of seeing interstellar flight achieved by the year 2100.

While Daedalus had relied on helium-3 propulsion, this depended on mining Neptune or Jupiter to produce sufficient helium-3; several other fuel sources and fusion types have been researched.[6]

Project Icarus focuses on the technology challenges of interstellar travel.[6] "The required milestones should be defined in order to get to a potential launch of such a mission. This should include a credible design, mission profile, key technological development steps and other aspects as considered appropriate." These goals are to be achieved by technical reports on engineering layout, functionality, physics, operation and other aspects of such an interstellar ship.[6]

  1. To design an unmanned probe that is capable of delivering useful scientific data about the target star, associated planetary bodies, solar environment and the interstellar medium.
  2. The spacecraft must use current or near future technology and be designed to be launched as soon as is credibly determined.
  3. The spacecraft must reach its stellar destination within as fast a time as possible, not exceeding a century and ideally much sooner.
  4. The spacecraft must be designed to allow for a variety of target stars.
  5. The spacecraft propulsion must be mainly fusion based (e.g., similar to Daedalus).
  6. The spacecraft mission must be designed so as to allow some deceleration for increased encounter time at the destination.

The team set out to describe the project requirements in the form of a set of Terms of Reference, which describe what is to be accomplished by the design study:[8]

  1. To design a credible interstellar probe that is a concept design for a potential mission in the coming centuries.
  2. To allow a direct technology comparison with Daedalus and provide an assessment of the maturity of fusion based space propulsion for future precursor missions.
  3. To generate greater interest in the real term prospects for interstellar precursor missions that are based on credible science.
  4. To motivate a new generation of scientists to be interested in designing space missions that go beyond our solar system.

Project Icarus was mainly formed as an initiative to re-energize the interstellar community. Tziolas had observed that many of the Daedalus team and other design-capable researchers had either retired or died and a "new generation of interstellar engineers" was needed.[6] With this in mind Project Icarus is mainly a designer capability exercise. The choice of mainly fusion fuel did not necessarily indicate the team were advocates of fusion propulsion, but was merely a vehicle for providing for a design study, within design constraints. The purpose behind Project Icarus has been defined to be:[7]
