Skytour Radio Presents: Talking TESS
Sunday June 3rd, 2018
In this episode of SkyTour News, we use our Exoplanet Round Up segment to take a closer look at TESS (The Transiting Exoplanet Survey Satellite) as we examine what it takes to search for planets outside of our solar system.Then, with continuing with our theme of how the universe was formed, we take an in depth look at the creation of our red neighbor, Mars.We look at the atmosphere it may have had and speculate on why it thinned out,we discuss it’s red color that most know the planet for and it’s magnetosphere and the impact that plays on the planet.
The Transiting Exoplanet Survey Satellite (TESS) is a space telescope for NASA’s Explorers program, designed to search for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission and was launched on April 18, 2018 atop a Falcon 9 rocket.
During its primary mission, it is expected to find more than 20,000 exoplanets,compared to about 3,800 exoplanets known when it launched. The primary mission objective for TESS is to survey the brightest stars near the Earth for transiting exoplanets over a two-year period.
With TESS, it will be possible to study the mass, size, density and orbit of a large cohort of small planets, including a sample of rocky planets in the habitable zones of their host stars.
Often referred to as the “Red Planet” because the reddish iron oxide prevalent on its surface gives it a reddish appearance that is distinctive among the astronomical bodies visible to the naked eye. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth.
The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons and there are ongoing investigations assessing the past habitability potential of Mars, as well as the possibility of extant life.
Future astrobiology missions are planned, including the Mars 2020 and ExoMars rovers.
SkyTour Radio explores the Universe in a down to Earth manner explaining the science we know in fun and bite-sized terms. Science is for everyone and people shouldn’t require an advanced degree to understand as long as it is delivered in an easy to follow way. From Black Holes to Extraterrestrial Life, we will explore the Universe like never before. Join us to check out such things as how stars form, how they live and, how our fate is intertwined with theirs. On the extraterrestrial life front, we will be speaking to the UFO and science arena’s top researchers and bring UFOlogy into the 21st century.
