Get your business into space
easily and affordably

Remote sensing. Satellite internet access.
Space debris removal. In recent years, private companies have been entering the space business,
which until now had been dominated by national governments,
thereby shaping a new market as they overcome sectoral barriers.

This has been made possible thanks to a new approach to satellites.
Rather than launching a few large ones, many small satellites are being sent up into space – so small rockets,
which offer greater scheduling flexibility than large ones, are attracting greater attention worldwide.

SPACE ONE is a launch services provider that uses small rockets.
We will offer the world’s shortest lead time from contractual engagement to launch,
as well as the world’s most frequent launching schedule.
With our dedicated launcher and launch site,
we will minimize the cost of putting satellites into orbit and help further expand space businesses.
