the planet's orbit and arrived at Mercury at a later date. While BepiColombo approached Venus before making its second flyby of the planet, two monitoring cameras and seven science instruments were switched on. Future missions The Venera-D spacecraft was proposed to Roscosmos in 2003 and the concept has been matured since then. It will be launched in 2029 and its prime purpose is to map Venus's surface using a powerful radar. The mission would also include a lander capable to function for a long duration on the surface. As of late 2018, NASA is working with Russia on the mission concept, but the collaboration has not been formalized. India's ISRO is developing the Shukrayaan-1 orbiter concept, which as of 2018, is in the configuration phase. It is proposed to be launched in 2023, but its funding has not yet been requested.BepiColombo, launched in 2018 to study Mercury, made two flybys of Venus, on October 15, 2020, and August 10, 2021. Johannes Benkhoff, project scientist, believes BepiColombo's MERTIS (Mercury Radiometer and Thermal Infrared Spectrometer) could possibly detect phosphine, but "we do not know if our instrument is sensitive enough". In June 2021, NASA announced two potential missions to Venus, VERITAS, an orbiter, and DAVINCI+, a combination orbiter/lander mission, both of the Discovery class. On October 6, 2021, the United Arab Emirates announced its intention to send a probe to Venus as soon as 2028. The probe would make observations of the planet while using it for a gravity assist to propel it to the Asteroid belt. Timeline of Venus exploration Unofficial names used during development are listed in italics. Past missions Current missions Missions under study Proposals To overcome the high pressure and temperature at the surface, a team led by Geoffrey Landis of NASA's Glenn Research Center produced a concept in 2007 of a solar-powered aircraft that would control a resistant surface rover on the ground. The aircraft would carry the mission's sensitive electronics in the relatively mild temperatures of Venus' upper atmosphere. Another concept from 2007 suggests to equip a rover with a Stirling cooler powered by a nuclear power source to keep an electronics package at an operational temperature of about . In 2020 NASA's JPL launched an open competition, titled "Exploring Hell: Avoiding Obstacles on a Clockwork Rover", to design a sensor that could work on Venus's surface.
