Space Waste and an Aurora Called Steve...

There is a crater on Mars , recently imaged by the Mars Reconnaisance Orbiter, which contains detritus from the 2004 landing of Opportunity.
I got to thinking that we have already begun leaving our waste on other worlds
The moon has over 70 space vehicles, including buggies and landers, golf clubs, discarded boots, flags, and various - over 100,000 pounds of debris.
I looked for statistics regarding waste on Mars, but beyond this list, it gets into alien conspiracy territory, so I quickly back-tracked.
Let's not forget the ring of debris orbiting our own planet - some 500,000 pieces (according to NASA in 2013).
Add to this the many Russian Verbera modules on Venus - although I imagine they've been cremated and crushed to a pulp, so at least there should be no trace...
Mercury didn't escape so lightly in 2008 , when the Messenger craft impacted, creating a whole new crater.

Currently surveying Titan for the last time, Cassini will eventually descend into Saturn, although given the toxic nature of the atmosphere, it will almost certainly be destroyed - and let's not forget the two Voyager craft, heading into deep space, followed by New Horizons, which achieved the most distant rendezvous yet with its flypast of Pluto, and following its encounter with MU69 in 2019, will become so much hi-tech driftwood floating through the heavens.
Our faltering steps into space have already left quite a trail , like a bored passenger tossing trash out of a car window on a long drive.
We humans are a messy bunch, but until we get the bill from the Intergalactic Sanitation Engineers, we'll be none the wiser.

On a lighter note , a new discovery in the majesty of the aurora ; a trail of green and purple lights which have been given the name of Steve.
No mushrooms required.
