One method of launching Horizons, is to go to Steam Library, right click on Elite: Dangerous in Games list, then double click on 'Play Elite Dangerous: Horizons'. NOTE: YOU NEED 'ELITE: HORIZONS' DLC, (but NOT the srv pack- that's just for paint jobs etc for the SRV), TO LAND ON PLANETS AND HAVE SRVs IN YOUR GAME. In the 'Out-fitting' section, when in a station that offers the service, the 'Optional Internal' bays are where you also purchase and fit an SRV into your ship. I have a feeling this is not entirely necessary to do, however it does help in detailing the planet and its content, so. However, 2nd time around, the planet I had selected seemed to reveal all its goodies to me once I'd scanned it from orbit, using the DSS (Detailed Surface Scanner), which you have to purchase and fit it in your ship's 'Optional Internal' bays. I was confronted with confusion and bewilderment the first time I tried to use the SRV. Things that are pretty much essential to know There are a number of things one needs to understand so as to be able to perform surface mining and reconnoiter planet-side, which frankly not many 'You-tube tutorials' go into great detail. There may well already be something like this buried away in the dusty pages of steam or other forums, but I thought I'd post this for the benefit of any new players currently stuck and possibly coming across this in a google search
