Today, the fourth Erebos lifter boosted Erebos-4 off the pad shortly before sunset, off into a suborbital trajectory before releasing the cold gas thrusters and firing the probe off into interplanetary space. This demonstrates the true capability of the Erebos lifter for unmanned payloads. We hope to explore the manned aspect of spaceflight by next year.

The Algor Desert States has propelled an artificial object, made by mere kerbals, beyond the orbit of Kerbin and out into the outer planets region.
