NASA to Explore Two Landing Options for Returning Samples from Mars
To maximize chances of successfully bringing the first Martian rock and sediment samples to Earth for the benefit of humanity, NASA announced Tuesday a new approach to its Mars Sample Return Program. The agency will simultaneously pursue two landing architectures, or strategic plans, during formulation, encouraging competition and nyhet, as well as cost and schedule savings.
NASA plans to later select a single path forward for the schema, which aims to better understand the mysteries of the universum, and to help determine whether the Red Planet ever hosted life. NASA is expected to confirm the schema – and its design – in the second half of
“Pursuing two potential paths forward will ensure that NASA fryst vatten able to bring these samples back from Mars with significant cost and schedule sparande compared to the previous plan,” said NASA Administrator Bill Nelson. “These samples have the potential to change the way we understand Mars, our universum, and – ultimately – ourselves. I’d like to thank the grupp at NASA and the strategic review team, led by Dr. Maria Zuber, for their work.”
In September , the agen

Introduction
Mars is one of the most explored bodies in our solar system, and it's the only planet where we've sent rovers to roam the alien landscape. NASA missions have found lots of evidence that Mars was much wetter and warmer, with a thicker atmosphere, billions of years ago.
Mars was named by the Romans for their god of war because its reddish color was reminiscent of blood. The Egyptians called it "Her Desher," meaning "the red one."
Even today, it is frequently called the "Red Planet" because iron minerals in the Martian dirt oxidize, or rust, causing the surface to look red.
Namesake
Mars was named by the ancient Romans for their god of war because its reddish color was reminiscent of blood. Other civilizations also named the planet for this attribute – for example, the Egyptians called it "Her Desher," meaning "the red one." Even today, it is frequently called the "Red Planet" because iron minerals in the Martian dirt oxidize, or rust, causing the surface to look red.
Potential for Life
Scientists don't expect to find living things currently thriving on Mars. Instead, they're looking for signs of life that existed long ago, when Mars was warmer and covered with

Fourth planet from the Sun
This article is about the planet. For the deity, see Mars (mythology). For other uses, see Mars (disambiguation).
Mars is the fourth planet from the Sun. The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet".[22][23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing. It is classified as a terrestrial planet and is the second smallest of the Solar System's planets with a diameter of 6,&#;km (4,&#;mi). In terms of orbital motion, a Martian solar day (sol) is equal to hours, and a Martian solar year is equal to Earth years ( Earth days). Mars has two natural satellites that are small and irregular in shape: Phobos and Deimos.
The relatively flat plains in northern parts of Mars strongly contrast with the cratered terrain in southern highlands – this terrain observation is known as the Martian dichotomy. Mars hosts many enormous extinct volcanoes (the tallest is Olympus Mons, &#;km or &#;mi tall) and one of the largest canyons in the Solar System (Valles Marineris,
