Analysis of Unknown

Unknown is this spacecraft jet,
This was supposed to move round all the orbits, all around the planets.
This might be the cause why thou art fueling it for a time without any set,
As yet nothing was known of why it is left unattended,
Everything is hazy, everything is held secret.
How far thou will project it  which orbit thou hast set for it, nothing is known as yet.
People are now annoyed and saying that who has left it useless on this planet.
