Last week I found a space SPAC (special purpose acquisition company) that I think has big potential. The SPAC is dMY Technology Group (NYSE: DMYQ), and it will soon merge with Planet Labs. Planet Labs owns and operates a fleet of around 200 imaging satellites in low-earth orbit. These satellites are constantly imaging and analyzing the earth. Customers include farmers, who can use the near-real-time data to maximize their crop yields.
