How many categories are there?
NASA's budget states that the #Falcon9 Full Thrust received Category 2 certification in January 2018. Category 2 certification allows Falcon 9 to launch medium risk NASA payloads. This certification is needed for the #SpaceX @NASA_TESS launch, which is currently NET March 20th.

so is the risk level describing the rocket risk or the acceptable payload risk? e.g. is JWT described as "high" or "low" risk?
-
Category 3 is for low-risk rockets aka high-risk payloads. The language is used interchangeably. It's confusing.

Will SpaceX need to re-certify when they introduce the Block 5?

Am I to read this that Category 1 would be human rated or is there some other rating for those systems?
-
Human rating is a separate issue from vehicle reliability (and really, a meaningless term as actually applied).
