Privately Owned Space Companies
Like publically traded space companies, the number of privately owned space companies continues to grow. It is not possible to invest in privately held companies by purchasing stock, so to contribute to their success it might be worth considering directly patronizing their services, making a donation (though usually not tax-deductible), or volunteering your time or abilities.

Of course, many private space companies are actively hiring and have job openings, so consider applying if you have the qualifications.
Note - To make sure the tax consequences are clear, always consult with your tax advisor before making donations. Be sure to thoroughly research any company before donating.
