Venera 7 (russia), semi-crashed, but sent back data from the ground t=475 c, oven temperature p=90 atmospheres. Venera 8 (russia), survived for 50 minutes on venus! Determined cameras could be used (if you could get one there) Mariner 10 (usa), successful flyby gravity measurements on the way to mercury. Venera 9 (russia), first picture of the surface of venus. Venera 10 (russia), sent back pictures, almost no wind! Pioneer venus orbiter (usa), transmitted data until 1992, radar map of the surface.
