NASA is grappling with budget pressures that may force the agency to scale back its ambitious Venus exploration program, potentially limiting progress to just one of three planned missions. The space agency had envisioned a comprehensive decade-long study of Earth's neighboring planet through multiple robotic probes.
The Venus exploration portfolio includes three distinct missions designed to study different aspects of the planet's atmosphere, surface, and geological history. Each mission was conceived to provide complementary data about Venus's extreme greenhouse effect and volcanic activity, building a comprehensive understanding of planetary evolution.
