Bennu Asteroid Sample Return Mission

The spacecraft has been orbiting Bennu now for a while and this year it will pick up a sample and return it to Earth (hopefully). If they are lucky, they may get some biological material (sorry 'organic') returned from the surface of the asteroid. They will do a bump of the spacecraft onto the surface in October this year to pick up the samples.

Primitive asteroids have not significantly changed since they formed nearly 4.5 billion years ago. Because of this, we hope to find organic molecules on Bennu like those that may have led to the origin of life on Earth.

OK, so Bennu has supposedly been around for billions of years. It has been out in space and being bombarded by cosmic radiation and whatever else is out there. I would expect it to have no sharp edges due to cosmic erosion. There should be no stick-like things, no coke cans, no litter, no plant-like things, etc because it is uninhabited for billions of years - right? The environment should be virgin rock without any space debris at all.

Just for info about this series of images they made into a panorama: (That says 5mm per pixel taken 250m above the surface)
This view of sample site Osprey on asteroid Bennu is a mosaic of images collected by NASA’s OSIRIS-REx spacecraft on May 26. A total of 347 PolyCam images were stitched together and corrected to produce the mosaic, which shows the site at 0.2 inches (5 mm) per pixel at full size. The spacecraft took these images during an 820-foot (250-meter) reconnaissance pass over the site, which is the closest Osprey has been imaged. The pass was designed to provide high-resolution imagery to identify the best areas within the site to collect a sample.

I will leave you to investigate if it grabs your imagination.


Just to whet your appetite, I have uploaded this one which I call 'the octopus' with is a 'something' 1/3rd along from the left hand end.
