First, just some fun stuff. The images shown below are from the OsirisREX asteroid reconnaissance spacecraft mission while it traversed the southern hemisphere of asteroid Bennu [Source].
The heart is an optical illusion which is in fact the biggest boulder on Bennu, clocking in at a whopping 45 meters in diameter. The original image is rotated 90 degrees and the boulder has been coloured in an a pink hue 😎
The boulder shown stuck to the surface of Bennu 
90 degrees of rotation and a dash of colour 
Here’s an alternate angle from a different image

The Asteroid Anchor – MicroGNExT
Asteroid regolith- a very interesting subject! The feasibility of attaching an astronaut safely to an asteroid has been a genuine practical engineering challenge set forth for real science to answer. Using physical experiments and simulation testing at the underwater astronaut training ground- The NBL (Neutral Buoyancy Lab) in Houston, Texas.
Back in early 2016, a project took place at Columbia University New York through the Columbia Space Initiative program, setting the stage for a unique friendly practical engineering challenge between teams from several competing universities.
The teams were tasked with building an anchor capable of surface penetration and ingress under human strength in a micro-gravity environment.
After completing the build and passing the necessary design milestones, the Columbia team were then invited to participate in the Neutral Buoyancy Lab simulation where it would be tested in the underwater spacewalk environment by astronauts. This is the same place that houses a replica of the international space station for astronaut training.
Will they get through to the end stage? Will their design succeed or fail? No spoilers, find out for yourself, its a great watch.
Enjoy the show!
