Hi there.!
This little thing is bound to make you happy.!
An identical copy of the image was immediately posted to the official-art channel:
1) 1s 2s
First 2 shells for an electron configuration
2) 114 102 116 114
octal encoding of the letters “LBNL”.
Lawrence Berkeley National Laboratory is where Mendelevium was first discovered
3) Orbital
Likely to guide our thinking toward electrons & thus electron configurations
4) 9TE
9th Transuranic Element, aka Mendelevium
5) Mendeleev Medal
6) 10-31
Unsolved
There was speculation that this was pointing us toward a date we may have been getting close to solving the tier.
