NASA’s Mars Reconnaissance Orbiter takes pictures of InSight Lander from Space

 

NASA Jet Propulsion Laboratory 

NASA - National Aeronautics and Space AdministrationPasadena, CA – On November 26th, 2018 NASA’s InSight mission knew the spacecraft touched down within an 81-mile-long (130-kilometer-long) landing ellipse on Mars. Now, the team has pinpointed InSight’s exact location using images from HiRISE, a powerful camera onboard another NASA spacecraft, Mars Reconnaissance Orbiter (MRO).

The InSight lander, its heat shield and parachute were spotted by HiRISE (which stands for High Resolution Imaging Science Experiment), which is onboard NASA’s Mars Reconnaissance Orbiter, in one set of images last week on December 6th, and again on Tuesday, December 11th.

NASA’s Opportunity Mars Rover seen by Mars Reconnaissance Orbiter

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA still hasn’t heard from the Mars Opportunity rover, but at least we can see it again.

A new image produced by HiRISE, a high-resolution camera aboard NASA’s Mars Reconnaissance Orbiter (MRO), shows a small object on the slopes of the Red Planet’s Perseverance Valley. That object is Opportunity, which was descending into the Martian valley when a dust storm swept over the region a little more than 100 days ago.

NASA's Opportunity rover appears as a blip in the center of this square. This image taken by HiRISE, a high-resolution camera onboard NASA's Mars Reconnaissance Orbiter, shows the dust storm over Perseverance Valley has substantially cleared. (NASA/JPL-Caltech/Univ. of Arizona )

NASA’s Mars Reconnaissance Orbiter photos reveal recurring steaks on Mars due to flowing sands, not water

 

Written by Laurie Cantillo / Dwayne Brown

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Dark features on Mars previously considered evidence for subsurface flowing of water are interpreted by new research as granular flows, where grains of sand and dust slip downhill to make dark streaks, rather than the ground being darkened by seeping water.

Continuing examination of these still-perplexing seasonal dark streaks with a powerful camera on NASA’s Mars Reconnaissance Orbiter (MRO) shows they exist only on slopes steep enough for dry grains to descend the way they do on faces of active dunes.

This inner slope of a Martian crater has several of the seasonal dark streaks called "recurrent slope lineae," or RSL, that a November 2017 report interprets as granular flows, rather than darkening due to flowing water. The image is from the HiRISE camera on NASA's Mars Reconnaissance Orbiter. (NASA/JPL-Caltech/UA/USGS)

NASA’s Mars Reconnaissance Orbiter views Curiosity Rover going up Mount Sharp

 

Written by Laurie Cantillo / Dwayne Brown
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Using the most powerful telescope ever sent to Mars, NASA’s Mars Reconnaissance Orbiter caught a view of the Curiosity rover this month amid rocky mountainside terrain.

The car-size rover, climbing up lower Mount Sharp toward its next destination, appears as a blue dab against a background of tan rocks and dark sand in the enhanced-color image from the orbiter’s High Resolution Imaging Science Experiment (HiRISE) camera. The exaggerated color, showing differences in Mars surface materials, makes Curiosity appear bluer than it really looks.

The feature that appears bright blue at the center of this scene is NASA's Curiosity Mars rover amid tan rocks and dark sand on Mount Sharp, as viewed by the HiRISE camera on NASA's Mars Reconnaissance Orbiter on June 5, 2017. (NASA/JPL-Caltech/Univ. of Arizona)

NASA’s Mars Reconnaissance Orbiter takes image of Opportunity Rover’s landing Platform in Eagle Crater

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A new observation from NASA’s Mars Reconnaissance Orbiter (MRO) captures the landing platform that the rover Opportunity left behind in Eagle Crater more than 13 years and 27 miles (or 44 kilometers) ago.

A series of bounces and tumbles after initial touchdown plunked the airbag-cushioned lander into the crater, a mere 72 feet (22 meters) across, on January 25th, 2004, Universal Time (January 24th, PST).

The scene includes Eagle Crater and Opportunity’s nearby parachute and backshell, from the April 10th, 2017, observation by MRO’s High Resolution Imaging Science Experiment (HiRISE) camera.

The bright landing platform left behind by NASA's Mars Exploration Rover Opportunity in 2004 is visible inside Eagle Crater, at upper right in this April 8, 2017, observation by NASA's Mars Reconnaissance Orbiter. (NASA/JPL-Caltech/Univ. of Arizona)

NASA’s Mars Reconnaissance Orbiter accomplished it’s 50,000th Orbit of Mars this week

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The most data-productive spacecraft yet at Mars swept past its 50,000th orbit this week, continuing to compile the most sharp-eyed global coverage ever accomplished by a camera at the Red Planet.

In addition, the spacecraft — NASA’s Mars Reconnaissance Orbiter (MRO) — recently aided preparations for NASA’s next mission to Mars, the InSight lander. Insight will launch next year on a mission to study the planet’s deep interior. Meanwhile, the orbiter continues diverse science observations of Mars and communications-relay service for two active Mars rovers, Curiosity and Opportunity.

In early 2017, after more than a decade of observing Mars, the Context Camera on NASA's Mars Reconnaissance Orbiter (MRO) surpassed 99 percent coverage of the entire planet. This mosaic shows that global coverage. (NASA)

NASA’s Mars Reconnaissance Orbiter looks back at the Earth

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – From the most powerful telescope orbiting Mars comes a new view of Earth and its moon, showing continent-size detail on the planet and the relative size of the moon.

The image combines two separate exposures taken on November 20th, 2016, by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter. The images were taken to calibrate HiRISE data, since the reflectance of the moon’s Earth-facing side is well known.

Here is a view of Earth and its moon, as seen from Mars. It combines two images acquired on Nov. 20, 2016, by the HiRISE camera on NASA's Mars Reconnaissance Orbiter, with brightness adjusted separately for Earth and the moon to show details on both bodies. Relative sizes and distance are correct. (NASA/JPL-Caltech/Univ. of Arizona)

Volunteers examine NASA’s Mars Reconnaissance Orbiter images to find areas worth further study

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Ten thousand volunteers viewing images of Martian south polar regions have helped identify targets for closer inspection, yielding new insights about seasonal slabs of frozen carbon dioxide and erosional features known as “spiders.”

From the comfort of home, the volunteers have been exploring the surface of Mars by reviewing images from the Context Camera (CTX) on NASA’s Mars Reconnaissance Orbiter and identifying certain types of seasonal terrains near Mars’ south pole.

This image shows spidery channels eroded into Martian ground. It is a Sept. 12, 2016, example from HiRISE camera high-resolution observations of more than 20 places that were chosen in 2016 on the basis of about 10,000 volunteers' examination of Context Camera lower-resolution views of larger areas.

NASA’s Mars Reconnaissance Orbiter data shows Gullies on Mars probably not created by Water

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – New findings using data from NASA’s Mars Reconnaissance Orbiter show that gullies on modern Mars are likely not being formed by flowing liquid water. This new evidence will allow researchers to further narrow theories about how Martian gullies form, and reveal more details about Mars’ recent geologic processes.

Scientists use the term “gully” for features on Mars that share three characteristics in their shape: an alcove at the top, a channel, and an apron of deposited material at the bottom.

Martian gullies as seen in the top image from HiRISE on NASA's Mars Reconnaissance Orbiter resemble gullies on Earth that are carved by liquid water. (NASA/JPL-Caltech/UA/JHUAPL)

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?”
