In its tireless search for space, NASA has set new directions. There are four possible missions to study the secrets of the Solar System. One of them is Jupiter's moon Io. Another, the moon Triton of Neptune. In addition, there are two missions to Venus in project.
Ship to venus
One of the selected proposals is DAVINCI +. They stand for Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging Plus. It aims to analyze the atmosphere of Venus to understand how it formed and evolved. They hope to determine if Venus ever had an ocean. DAVINCI + would dive into the inhospitable atmosphere of Venus to accurately measure its composition to the surface.
With the same target planet is VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy). It would map the surface of Venus to determine the geological history of the planet. He hopes to understand why Venus developed so differently from Earth. It would create three-dimensional reconstructions of the planet's topography. It is the second of the missions to Venus that are considered.
To infinity and beyond
There is a third proposal: IVO (Io Volcano Observer). I would explore Jupiter's moon, Io. I would learn how tidal forces shape planetary bodies. It is heated by the constant crushing of Jupiter's gravity. It is the most volcanically active body in the solar system. Little is known about the specific characteristics of Io, as if there is an ocean of magma inside. Using close overflights, IVO would evaluate how magma is generated and erupts in Io.
The fourth selection includes TRIDENT, a mission that Triton would explore. It is a unique and very active icy moon of Neptune. They want to understand the paths to habitable worlds at tremendous distances from the Sun. Triton is an exciting exploration target. It has the potential to house an inland ocean,
According to a statement, Each of the four selected nine-month studies will receive three million dollars. They must develop and mature concepts and conclude with a Conceptual Study Report. After evaluating the conceptual studies at the end of the year, NASA will continue to develop up to two missions to the flight.
