NASA has announced that it will send two probes to Venus towards the end of the decade, in what will be the first time the agency has visited the hellish planet in more than 30 years.

In a statement on Wednesday, NASA said the two separate missions, called VERITAS and DAVINCI+, would launch some time between 2028 and 2030 and cost around $500 million each. VERITAS stands for Venus Emissivity, Radio Science, InSAR, Topography and Spectroscopy, and DAVINCI+ for Deep Atmosphere of Venus Investigations of Noble Gases, Chemistry and Imaging. The plus sign alludes to improvements on a past proposal.
