There have been proposals (1, 2, 3, 4,...) to send probes into the atmosphere of Venus, but these proposals haven't been selected by space agencies to fly. Some balloons were sent in the 80's, but missions towards Venus are few and far between.
With the recent discovery of significant amounts of phosphine in the atmosphere of Venus, there are even more reasons to send probes in situ. Can we expect the exploration of Venus to become a higher priority for space agencies? Perhaps even a flagship mission towards Venus? Or on the contrary will this discovery have no impact on the agenda of space agencies?
