NASA Mission

NASA's Science Mission Directorate (SMD) organizes its work into five broad scientific pursuits: Earth Science, Planetary Science, Heliophysics, Astrophysics, and Biological and Physical Sciences.

• Earth Science: Study planet Earth from space to advance scientific understanding and meet societal needs
• Planetary Science: Advance scientific knowledge of the origin and history of the solar system, the potential for life elsewhere, and the hazards and resources present as humans explore space
• Heliophysics: Understand the Sun and its effects on Earth and the solar system
• Astrophysics: Discover the origin, structure, evolution, and destiny of the universe, and search for Earth-like planets
• Biological and Physical Sciences: Learn how biological and physical systems work at a fundamental level by studying them in space.

​No mention of aliens.
In science, it is smarter to ignore the unqualified or conspiracy theorists.
In religion, it is smarter to ignore prophecies.
Stay grounded.
