Space Ambitious

NASA’s upcoming announcement for their unambitious plans in which they may or may not be seeking international partners got me thinking about what is ambitious, what is not and the relationship between agencies.

If we take ambitious to mean ‘Intended to satisfy high aspirations’ then for me an ambitious space project would mean landing people on the moon, setting up a permanent base on the moon and after that setting off for a manned mission to Mars (one-way or return). That would truly be ambitious.

So with that in mind which space agencies are ambitious? Well I have only found three space agencies that have real plans for a manned mission to the moon (that means actually landing astronauts on the moon) and that is China’s CNSA, Europe’s ESA and Russia’s RFSA. The other ‘major’ players such as NASA, JAXA and ISRO seem to have no real current plans.

While I completely support the major space agencies working together it’s imperative that they plan ambitious missions together, for the benefit of everyone without letting petty ideological/political nonsense get in the way of achieving major goals. If NASA continues to exclude China (especially when the other nations have no problem) from projects such as the ISS then they may very well find themselves losing out as China goes it alone or works with Russia to meet its targets. As the saying goes, keep your friends close and your enemies closer!

Though finally I would like to add that I personally couldn’t care less weather American short-sightedness back-fires on them (again).

Multi-generational interstellar travel; ethics.

Following on from the 2005 objections debate here about multi-generational interstellar travel I want to put the ethical issue of ‘condemning’ future generations to a limited life on board the ship.

Basically the arguments against focus on the future generations not wanting to pursue their forefathers ambitions and having a limited life (not being able to have a wide selection of human social relations, being cut-off from Earth society (at least in a physical way)).

According to British anthropologist Robin Dunbar the amount of people we know and keep in contact with lies between 100 and 250, meaning there is a good chance on a ship with a starting crew of say 2000 people which of course will expand through the generations it is unlikely that a situation will arise where everyone knows everyone.

As for the idea that these future generations will be cut-off from the developments back on Earth this is potentially true should there be a communications malfunction otherwise audio and visual communication and learning will continue to be possible as well as uploads and downloads.

Comparisons have been made to past explorers setting out to find new land on Earth and colonising islands, effectively stranding their future generations to the island till the time came about that allowed travel much easier and faster.

In short I see absolutely no issue with setting out on a multi-generational adventure providing that the crew consisted of at least 2000 people.

Multi-generational interstellar travel; features & facilities.

When you enter a starship designed to be lived on for generations without stopping or resupplying what would you expect to find?

Features & facilities
Garden – Producing natural oxygen and food, chicken coop.
Recreational – Bar/disco.
Accommodation – Combination of family rooms and dormitories.
Health – Sport and exercise rooms (gym, football).
Educational – School and learning rooms.
Medical – Sick bay inc birthing facilities, surgery.
Science – Various labs for each scientific field, psychiatry/psychology rooms.
Engineering – Engine room, research lab, storage facility.
Manufacturing – Manufacturing rooms inc clothes, new tech, repairs/spare parts.
Command – Command room and centralised ship controls.
Misc – Detention room, meeting rooms, creative/art space.

Did I miss something?

Multi-generational interstellar travel; crew.

How many?
Previous estimates have suggested anywhere between 150 and 3 million.

Bearing in mind the psychological effects and the breeding requirement to keep such a ship going till it reaches its destination and fulfills its mission objectives.

With this is mind I would suggest a crew of 2000. This would allow (with additional sperm and embryo storage) a big enough pool to stop inbreeding and genetic flaws as well as alleviate any negative psychological effects as a result of everyone knowing everyone.

In order to aid a healthy gene pool the crew should be a mix of people from every continent on Earth. This will also act as a true representation of Earth and hopefully act as a tool to unite humanity. There should be a 50/50 male/female ratio and everyone should be of suitable reproduction age.

Departments & skills
Science – Computer, social, physics, biology, chemistry, geologists etc
Medical – A variety of different field specialist doctors.
Engineering – A variety of different field engineers.
Command/Tactical – In-case of communication issues with Earth an independent on-board command.
Civilian – Recreation, social and general non-essential crew.

Selection process
Relevant expertise

That’s just my first thoughts, what else? Care to expand?
