NASAs DAVINCI-oppdrag vil studere opprinnelsen, evolusjonen og den nåværende tilstanden til Venus i enestående detalj fra nær toppen av skyene til planetens overflate. Oppdragets mål er å bidra til å svare på mange spørsmål om vår naboplanet, spesielt om Venus noen gang har vært våt og beboelig som Jorden. Kreditt: NASAs Goddard Space Flight Center
I fjor, NASA valgt de DAVINCI oppdrag som en del av Discovery-programmet. Den vil undersøke opprinnelsen, evolusjonen og nåværende tilstanden til[{” attribute=””>Venus in unparalleled detail from near the top of the clouds to the planet’s surface. Venus, the hottest planet in the solar system, has a thick, toxic atmosphere filled with carbon dioxide and an incredible pressure of pressure is 1,350 psi (93 bar) at the surface.
Named after visionary Renaissance artist and scientist Leonardo da Vinci, the DAVINCI mission Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging will be the first probe to enter the Venus atmosphere since
Now, in a recently published paper, NASA scientists and engineers give new details about the agency’s Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging (DAVINCI) mission, which will descend through the layered Venus atmosphere to the surface of the planet in mid-2031. DAVINCI is the first mission to study Venus using both spacecraft flybys and a descent probe.
DAVINCI, a flying analytical chemistry laboratory, will measure critical aspects of Venus’ massive atmosphere-climate system for the first time, many of which have been measurement goals for Venus since the early 1980s. It will also provide the first descent imaging of the mountainous highlands of Venus while mapping their rock composition and surface relief at scales not possible from orbit. The mission supports measurements of undiscovered gases present in small amounts and the deepest atmosphere, including the key ratio of hydrogen isotopes – components of water that help reveal the history of water, either as liquid water oceans or steam within the early atmosphere.
