SPACE FREEDOM

FREEDOM Falling and Re-Entering Equipment called DOM

What is FREEDOM?
Main specifications

FREEDOM (Membrane Deployable Orbit Detachment Device Space Demonstration Satellite) is a nano-satellite specialized for membrane deployment that was developed jointly by our company and Tohoku University to demonstrate the reliable drive of "DOM" in outer space. It is a small artificial satellite.
On September 29, 2014, it was selected by JAXA for a mission to be launched from the Japanese Experiment Module of the International Space Station "Kibo".

主要諸元

FREEDOM released into space counts a certain amount of time, and then
Expand DOM1500 (membrane size 1500mm square).
After deployment, it is expected to re-enter the Earth's atmosphere in about a month.
We evaluate the performance of DOM using orbit information from public institutions.

minimum success

  • Identification of initial trajectory using information from public institutions
  • Accumulation of orbit transition information for one month

Full success

  • Accumulation of orbit transition information until re-entry into the Earth's atmosphere
  • Performance evaluation through comparison and verification with simulation results

Extra success

  • Re-entry into the Earth's atmosphere within a month
  • Investigation of the influence of weathervane stability on orbit transition

With the practical application of the membrane deployment orbit departure device

  • Establishment of a method for leaving orbit for small satellites
  • Contributing to the standardization of the world's first means of deorbiting

Mission success

FREEDOM was launched on December 9, 2016 and transported to the International Space Station. It entered orbit on January 16, 2017 and re-entered the Earth's atmosphere approximately 22 days later.

This demonstrated the possibility of preventing satellites from turning into space debris.

FREEDOM is currently orbiting at an altitude of approximately 300 km. As early as this week...
2017.02.06
Public institutions have stopped providing orbit information for FREEDOM (ID: 41930) as of February 6th.
2017.02.06
The provision of orbital information for FREEDOM (ID:41930) by public institutions ended on February 6th.
As a result, FREEDOM left its orbit and is thought to have re-entered the atmosphere on the 7th.

Here are some messages installed in "FREEDOM".

(Published as original)

It's true that the universe is incredibly large, but that doesn't mean that trash is relatively small.
Don't call it a husk of romance or the remains of a dream, just try to ``return home cleaner than when you left.'' I hope the experiment is a success! We are rooting for you!

(28 year old female)

As the name FREEDOM suggests, we hope that the debris problem will be solved and that access to space will continue to be peaceful and free. I hope that it will become the foundation for that.

(44 year old male)

Please do your best to keep the universe clean! A universe without space debris! Please do your best for those who will go to space in the future. I'm rooting for you.

(11 years old male)

Safe and clean space environment for the next generation
