NASA’s Curiosity Mars rover is now performing Sol 2451 weekend tasks.

Reports Roger Wiens, a geochemist at Los Alamos National Laboratory in Los Alamos, New Mexico: “Curiosity has been a bit down lately-in elevation. After exploring the top of Vera Rubin Ridge (VRR) last year, the rover descended into a trough south of the ridge, dropping as much as 15 meters in elevation this spring to explore part of the clay-bearing unit.”

Wiens adds that Curiosity is now back to the highest elevation that it achieved before it left the ridge, about -4140 meters relative to the reference level representing zero elevation on Mars.

Climb higher

“Curiosity will continue to climb higher as it explores the rest of the Glen Torridon and then moves on to the sulfate unit and Greenheugh Pediment,” Wiens notes.

The rover team recently planned activities for the rover over the weekend.

Curiosity is wrapping up activities at the base of “Harlaw Rise” and will then drive further up the rise.

Weekend plan

On the first sol of the weekend plan the rover is on tap to mostly nap to recharge batteries.

Some Hazcam imaging will be done and Mastcam will take some nighttime images, according to the plan.

On the second sol, ChemCam is slated to shoot three targets near the rover: “Red_Point”, “North_Sea,” and “Roineva.”

Crater rim imaging

Mastcam is slated to take a crater rim extinction image. The arm will be deployed for imaging of gnarly rocks with the Mars Hand Lens Imager (MAHLI) and analysis with the Alpha Particle X-Ray Spectrometer (APXS).

Target names are “Earn” and “Magnus Bay.”

On the plan, Navcam will take zenith and superhorizon movies, and Mastcam will take another crater rim extinction image. Mastcam will image “Harlaw_Rise” and the “Tayside” and “Buckie” targets.

Drive ahead

After that, Wiens concludes, the plan for the rover is to do some deck monitoring; Navcam will do a 360 degree dust devil survey. The rover will drive 115 feet (35 meters) which should take it up “Harlaw Rise.”

As always, dates of planned rover activities are subject to change due to a variety of factors related to the Martian environment, communication relays and rover status.

NASA’s Curiosity Mars rover is now performing Sol 2450 science duties.

“We are continuing our exploration of Glen Torridon (the clay-bearing unit) and the varied lithologies exposed in this area of Gale crater, including more rubbly bedrock that is mixed with sand, and more coherent bedrock exposed both in the ground and capping prominent ridges,” reports Lucy Thompson, a planetary geologist at the University of New Brunswick, Fredericton, New Brunswick, Canada.

Perfect position

A recent drive by the robot put the Mars machinery about 30 feet (9 meters) away from Harlaw and in a “perfect position” to get some context Mastcam mosaics of the area that will help scientists interpret the results of our planned closeup investigation of this area, Thompson notes.

Rubbly bedrock

“We will get a short morning APXS integration, closeup MAHLI images and ChemCam on a target “Tolsta,” ChemCam only on a target ‘Yell Sound’ and accompanying Mastcam imaging of the workspace to continue monitoring the composition and texture of the rubbly bedrock as we traverse the Glen Torridon region,” Thompson reports.

Optical depth

A Navcam dust devil survey and suprahorizon movie are also planned. The suprahorizon movie will look for clouds and the optical depth of the atmosphere.

As well as monitoring activities, as the APXS strategic planner for this week, Thompson helped select the Tolsta target and prepared a weekly instrument update for the science team.

NASA’s Lunar Reconnaissance Orbiter (LRO) has snapped new imagery of China’s Yutu-2 rover that is still on the move!

The orbiter’s Lunar Reconnaissance Orbiter Camera (LROC) shows the wheeled rover about 426 feet (130 meters) west of the Chang’e-4 lander.

Once a month, LRO passes over the Chang’e 4 landing site, allowing LROC to capture a new image. LROC has now imaged the site five times (since the landing) on January 3 and observed Yutu-2 to have traveled a total of 610 feet (186 meters) – the distance measured using the rover tracks.

Slower progress

“Progress over the past two months has been slower than in previous months,” reports Mark Robinson, the LROC principal investigator at Arizona State University. “Perhaps the rover has found some interesting geology and is lingering to collect a comprehensive set of measurements!”

LROC will keep imaging the site as the Sun angles and look angles vary, to better understand the reflectance of this region, Robinson said, “and to watch Yutu-2 keep on roving and exploring!”

China’s Chang’e-4 lander and the Yutu-2 have resumed work for the seventh lunar day on the farside of the Moon after “sleeping” during the extreme cold night.

Both are in normal working condition, according to the Lunar Exploration and Space Program Center of the China National Space Administration (CNSA).

China’s Xinhua news agency reports that the lander woke up at 9:45 a.m. Thursday, and the rover, Yutu-2 (Jade Rabbit-2), awoke at 1:26 p.m. Wednesday.

Scientific studies

The Yutu-2 rover has traveled more than 696 feet (212 meters) across the lunar landscape to conduct scientific studies.

NASA’s Curiosity Mars rover is now performing Sol 2449 science duties.

Reports Scott Guzewich, an atmospheric scientist at NASA/GSFC in Greenbelt, Maryland: A recent plan wrapped up time for the rover to study the Teal Ridge outcrop, then the robot is to drive toward the next waypoint in the clay-bearing unit of Gale Crater.

Lien list

There were several science tasks on our lien list to complete first, including Chemistry and Camera (ChemCam) laser-induced breakdown spectroscopy (LIBS) targets on the “rubbly” material in front of the outcrop.

Mars researchers identified a target named “Glencoe”), one on a dark vein structure within the outcrop (termed “Glenbuchat,” – incredible layered structure in Teal Ridge)

Also produced was a Mastcam multispectral image (where Mastcam uses its different filters to get a better understanding of a rock’s chemistry) of the “Beauly” target that received a thorough cleaning with the dust removal tool last week, Guzewich points out.

Next waypoint

“After the drive, we’ll be about halfway to our next waypoint and we’ll stop to conduct some post-drive science including imaging of the surrounding area and some late afternoon [environmental] ENV activities including a Mastcam sky survey (to help understand the properties of the airborne dust) and a Navcam zenith movie to search for clouds,” Guzewich adds.

“The ‘Aphelion Cloud Belt’ season is nearly upon us,” Guzewich concludes, “and we expect the skies to be getting much cloudier in the sols and weeks ahead.”

New road map

Meanwhile a new Curiosity Traverse Map Through Sol 2447 has been issued.

The map shows the route driven by NASA’s Mars rover Curiosity through the 2447 Martian day, or sol, of the rover’s mission on Mars (June 25, 2019).

In July the Mutual UFO Network (MUFON) celebrates 50 years of investigating and promoting research on the unidentified flying object phenomenon.

The all-volunteer, non-profit, scientific-based organization has endeavored since 1969 to hunt down answers about baffling vehicles of unknown origin.

The Pentagon’s Advanced Aerospace Threat Identification Program (AATIP) was created to research and investigate Unidentified Aerial Phenomena (UAP) including numerous videos of reported encounters, three of which were released to the public in 2017.

After five decades, has there been any scientific pay dirt in studying UFOs? Are we inching closer to the truth that is perhaps out there?

Weirdness in the sky, then jumping to alien visitation from afar is a big leap. So too are interdimensional beings, wormhole hooligans, or time travelers. But who knows?

NASA is investing in a new research program – the Exploring Ocean Worlds (ExOW) project. The five-year effort is geared to understand the potential for life in the outer solar system and establishes a new Network for Ocean Worlds.

The focus of the effort would address a central question in astrobiology research today: On which ocean worlds, and using which measurements, do we have the highest probability of finding life beyond Earth within the next human generation?

Accelerating research

The project will form a cornerstone for NASA’s new Network for Ocean Worlds (NOW). NOW is an initiative aimed at accelerating research on planetary bodies with liquid water oceans that may harbor life or conditions that could support it by coordinating scientific studies nationwide that help advance understanding of ocean worlds.

The network will be co-led by Christopher German, a senior scientist at Woods Hole Oceanographic Institution, together with Alison Murray at the Desert Research Institute and Alyssa Rhoden at the Southwest Research Institute.

NOW is the latest of four research coordination networks to be established by NASA that will enable research covering different aspects of the search for life beyond Earth.

Best bet

“If we hope to find evidence of life beyond Earth, within the next human generation, then our best bet is to look toward the growing list of ice-covered ocean worlds right here in our own solar system,” said German in a press statement.

“And looking further ahead,” German added, “if we want to understand the range of possible conditions that could support life anywhere beyond Earth, then we will simultaneously need to both continue exploring our own ocean for examples of extremes under which life can exist and continue developing exploration technologies that will be useful on any ocean world, including Earth.”

Liquid water oceans

Ocean worlds beyond Earth have been a key research focus for NASA’s Planetary Science Division ever since the confirmation of ice-covered liquid water oceans on Jupiter’s moons Europa and Ganymede and, subsequently, Saturn’s moons Enceladus and Titan.

Ultimately, the ExOW team intends to construct a comprehensive theoretical model, informed and tested by experimental efforts, that connects a broad range of physical and chemical processes within an ocean system. The model will help determine the potential of that system to harbor life and to reveal evidence of that life to future NASA missions.

“Our approach is designed to provide a predictive framework applicable to all ocean worlds of this type, but will have clear, immediate and direct relevance to two high priority astrobiology targets: Europa and Enceladus,” said German. The project is designed to be completed just in time for the launch of Europa Clipper, NASA’s next major mission to an ocean world, which is currently scheduled for launch in the early 2020s.

NASA’s Curiosity Mars rover is busily performing Sol 2447 science tasks.

“Curiosity is still perched on top of Teal Ridge to investigate a fascinating outcrop that caps the ridge,” reports Kristen Bennett, a planetary geologist at the USGS in Flagstaff, Arizona.

Scientists have been characterizing the ridge-capping material, but also devoting time to use the Sample Analysis at Mars (SAM) Instrument Suite to look for methane.

Ridge-capping material is visible in the foreground, and the background shows where Curiosity is going to drive to next. Image taken by Curiosity’s Navcam Left B camera on Sol 2439, June 17, 2019.

Dog’s eye mosaic

A recently scripted three-sol plan includes a Mars Hand Lens Imager (MAHLI) dog’s eye mosaic of the target “Stack of Glencoul.”

“Typically the arm is positioned such that the MAHLI instrument is looking down on a target. In a dog’s eye observation, the rover arm is positioned so that it looks at the target from the side. The team decided we should do a dog’s eye mosaic at this location so we can look directly at the laminations within these rocks,” Bennett explains.

 

Laminations

The robot’s Alpha Particle X-Ray Spectrometer (APXS) will also target Stack of Glencoul in the weekend plan so Mars researchers will be able to pair compositional information with these images. MAHLI will also take images of the “Yesnaby Stacks” target to document a different part of the outcrop that exhibits laminations.

Also included in the plan are a Navcam dust devil movie, Mastcam images of the “Sandyhills” target to monitor changes due to wind, a Chemistry and Camera (ChemCam) observation of Yesnaby Stacks, and an addition to the “Beauly” Mastcam mosaic to complete our Mastcam coverage of this outcrop, Bennett adds.

Play it again SAM

“The SAM instrument is also featured prominently in this weekend’s plan. The team is using SAM to periodically search for methane in the atmosphere,” Bennett concludes, “so SAM will ‘sniff’ the air during the night on the second sol and then spend part of the weekend analyzing this sample of the martian atmosphere.”
