NASA takes it’s next steps towards on the Journey to Mars

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – July is always a good time to assess where U.S. human space exploration has been and where it’s going. This year, July 20th marks the 40th anniversary of Viking, which in 1976 became the first spacecraft to land on Mars.

And just seven years — to the day — before Viking’s amazing feat, humans first set foot on another world, when Neil Armstrong and Buzz Aldrin set the Apollo 11 lunar module Eagle down in the moon’s Sea of Tranquility on July 20th, 1969.

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Juno is now poised to shine a spotlight on the origins and interior structure of the largest planet in our solar system.

As we wait for Juno’s first close-up images of Jupiter (to be taken August 27th during the spacecraft’s next pass by the planet), NASA continues to explore our solar system to help answer fundamental questions about how we came to be, where we are going and whether we are alone in the universe.

NASA to begin final design and construction of Mars 2020 rover

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – After an extensive review process and passing a major development milestone, NASA is ready to proceed with final design and construction of its next Mars rover, currently targeted to launch in summer of 2020 and arrive on the Red Planet in February 2021.

The Mars 2020 rover will investigate a region of Mars where the ancient environment may have been favorable for microbial life, probing the Martian rocks for evidence of past life. Throughout its investigation, it will collect samples of soil and rock, and cache them on the surface for potential return to Earth by a future mission.

NASA studies Mars Canyons for signs of liquid water

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Puzzles persist about possible water at seasonally dark streaks on Martian slopes, according to a new study of thousands of such features in the Red Planet’s largest canyon system.

The study published today investigated thousands of these warm-season features in the Valles Marineris region near Mars’ equator. Some of the sites displaying the seasonal flows are canyon ridges and isolated peaks, ground shapes that make it hard to explain the streaks as resulting from underground water directly reaching the surface.

Blue dots on this map indicate sites of recurring slope lineae (RSL) in part of the Valles Marineris canyon network on Mars. RSL are seasonal dark streaks that may be indicators of liquid water. The area mapped here has the highest density of known RSL on Mars. (NASA/JPL-Caltech/Univ. of Arizona)

NASA’s Curiosity Mars Rover may be used to search for Water on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Ever since it was announced that there may be evidence of liquid water on present-day Mars, NASA scientists have wondered how best to further investigate these long, seasonally changing dark streaks in the hope of finding evidence of life — past or present — on the Red Planet.

“It’s not as simple as driving a rover to a potential site and taking a scoop of soil,” said Jim Green, NASA’s director of planetary science. “Not only are these on steep slopes, we need to ensure that planetary protection concerns are met. In other words, how can we search for evidence of life without contaminating the sites with bugs from Earth?”

NASA’s Mars Reconnaissance Orbiter data shows Dust Storm Pattern on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – After decades of research to discern seasonal patterns in Martian dust storms from images showing the dust, but the clearest pattern appears to be captured by measuring the temperature of the Red Planet’s atmosphere.

For six recent Martian years, temperature records from NASA Mars orbiters reveal a pattern of three types of large regional dust storms occurring in sequence at about the same times each year during the southern hemisphere spring and summer. Each Martian year lasts about two Earth years.

“When we look at the temperature structure instead of the visible dust, we finally see some regularity in the large dust storms,” said David Kass of NASA’s Jet Propulsion Laboratory, Pasadena, California.

This graphic presents Martian atmospheric temperature data as curtains over an image of Mars taken during a regional dust storm. The temperature profiles extend from the surface to about 50 miles up. Temperatures are color coded, from minus 243 degrees Fahrenheit (purple) to minus 9 F (red).

NASA Spacecraft images indicate Tsunamis on Mars shaped it’s Coastal areas

 

NASA’s Ames Research Center

NASA - National Aeronautics and Space AdministrationMoffett Field, CA – New NASA-funded research indicates that giant tsunamis played a fundamental role in forming Martian coastal terrain, removing much of the controversy that for decades shrouded the hypothesis that oceans existed early in Mars’ history.

“Imagine a huge wall of red water the size of a high-rise building moving towards you at the speed of a jetliner,” said J. Alexis P. Rodriguez, former NASA Postdoctoral Program fellow at NASA’s Ames Research Center in California’s Silicon Valley, and senior research scientist at the Planetary Science Institute in Tucson, Arizona. “That could be a fair way to picture it in your mind.”

NASA’s Mars Reconnaissance Orbiter data reveals most recent Ice Age on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Scientists using radar data from NASA’s Mars Reconnaissance Orbiter (MRO) have found a record of the most recent Martian ice age recorded in the planet’s north polar ice cap.

The new results agree with previous models that indicate a glacial period ended about 400,000 years ago, as well as predictions about how much ice would have been accumulated at the poles since then.

The results, published in the May 27th issue of the journal Science, help refine models of the Red Planet’s past and future climate by allowing scientists to determine how ice moves between the poles and mid-latitudes, and in what volumes.

Climatic cycles of ice and dust build the Martian polar caps, season by season, year by year, and periodically whittle down their size when the climate changes. This image is a simulated 3-D perspective view, created from image data taken by the THEMIS instrument on NASA's Mars Odyssey spacecraft. (NASA/JPL/Arizona State University, R. Luk)

NASA’s SOFIA flying observatory sees Atomic Oxygen in Atmosphere of Mars

 

Written by Kassandra Bell, SOFIA Science Center
NASA’s Ames Research Center

NASA - National Aeronautics and Space AdministrationMoffett Field, CA – An instrument onboard the Stratospheric Observatory for Infrared Astronomy (SOFIA) detected atomic oxygen in the atmosphere of Mars for the first time since the last observation 40 years ago. These atoms were found in the upper layers of the Martian atmosphere known as the mesosphere.

Atomic oxygen affects how other gases escape Mars and therefore has a significant impact on the planet’s atmosphere. Scientists detected only about half the amount of oxygen expected, which may be due to variations in the Martian atmosphere.
