With modern technology and years of human exploration, it’s easy to think we’ve seen pretty much everything there is to see. But occasionally, people discover incredible treasures that remind us just how much is still waiting out there to be found.

Ralph Mirebs is a Russian photographer who was exploring the area outside Baikonur in Kazakhstan, when he came across a huge abandoned. Fortunately for all of us, he decided to take a peek inside.

As he would later find out, the structure was a relic from the Soviet Union’s space program.

It was abandoned after the Soviet Union collapsed in 1993.

The building was designed as a hangar for housing… space shuttles.

Three space shuttles were constructed here, but only one went on a mission – an unmanned orbit.

And they had just been left there ever since.

Since the building was designed to battle the elements, everything inside was relatively well preserved.

But over 20 years after they were abandoned, the space shuttles may need some work before you try taking off in one.

The pressure systems that once protected them went into disrepair long ago, and alot of dust and debris have collected since.

But the size of the place is still impressive, that’s for sure.

Without the right upkeep, these incredible artifacts of early space exploration would eventually be lost forever.

It’s somewhat surprising how well preserved the structure is, despite decades of abandonment.

Those holes on the nose of the shuttle are actually thrusters.

They were to be used to make small flight corrections while in space.

The cockpit might just be the most well preserved.

Just look at this thing!

This is pretty cool.

The hatch and pressure control systems are in decent shape, too.

And this is what the interior of the fuselage looks like.

It is incredible to think that all of this was sitting untouched for so long. Makes you think what else might be out there waiting to be found.
