For the first time, we can hear the "sounds" of wind on Mars as captured by the scientific instruments on NASA's InSight robotic lander. From NASA:
"Capturing this audio was an unplanned treat," said Bruce Banerdt, InSight principal investigator at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California...
Two very sensitive sensors on the spacecraft detected these wind vibrations: an air pressure sensor inside the lander and a seismometer sitting on the lander's deck, awaiting deployment by InSight’s robotic arm. The two instruments recorded the wind noise in different ways. The air pressure sensor, part of the Auxiliary Payload Sensor Subsystem (APSS), which will collect meteorological data, recorded these air vibrations directly. The seismometer recorded lander vibrations caused by the wind moving over the spacecraft's solar panels, which are each 7 feet (2.2 meters) in diameter and stick out from the sides of the lander like a giant pair of ears.

Since the InSight robotic lander touched down on Mars last week, engineers have been putting its scientific instruments through their paces. This included extending the lander's 6 foot (2 meter) robotic arm that will be used to deploy instruments and take images of the Martian surface.
"Today we can see the first glimpses of our workspace," said mission principal investigator Bruce Banerdt of NASA's Jet Propulsion Laboratory in Pasadena, California.
People, these images are from the surface of Mars! MARS!

After sticking a perfect landing on the Martian surface this afternoon, NASA's InSight robot lander has successfully deployed its solar panels. Tomorrow, InSight will fire up its scientific instruments and get to work collecting data about the planet's interior. From NASA/JPL-Caltech:

NASA's InSight has sent signals to Earth indicating that its solar panels are open and collecting sunlight on the Martian surface. NASA's Mars Odyssey orbiter relayed the signals, which were received on Earth at about 5:30 p.m. PST (8:30 p.m. EST). Solar array deployment ensures the spacecraft can recharge its batteries each day. Odyssey also relayed a pair of images showing InSight's landing site.
"The InSight team can rest a little easier tonight now that we know the spacecraft solar arrays are deployed and recharging the batteries," said Tom Hoffman, InSight's project manager at NASA's Jet Propulsion Laboratory in Pasadena, California, which leads the mission. "It's been a long day for the team. But tomorrow begins an exciting new chapter for InSight: surface operations and the beginning of the instrument deployment phase..."
In the coming days, the mission team will unstow InSight's robotic arm and use the attached camera to snap photos of the ground so that engineers can decide where to place the spacecraft's scientific instruments. It will take two to three months before those instruments are fully deployed and sending back data.
In the meantime, InSight will use its weather sensors and magnetometer to take readings from its landing site at Elysium Planitia — its new home on Mars.
Life on Mars has always been a standard science fiction topic, but Season 2 of National Geographic’s “Mars” shows how real and attainable that focus has become. The first season of the docudrama series aired in 2016 and was notable for its blending of fiction and science-based documentary, a format the show has maintained and improved. Read the rest

Once the rover is on the planet’s surface, a suitable location will be found to deploy the helicopter down from the vehicle and place it onto the ground. The rover then will be driven away from the helicopter to a safe distance from which it will relay commands. After its batteries are charged and a myriad of tests are performed, controllers on Earth will command the Mars Helicopter to take its first autonomous flight into history.
“We don’t have a pilot and Earth will be several light minutes away, so there is no way to joystick this mission in real time,” said (Mimi Aung, Mars Helicopter project manager at NASA's Jet Propulsion Laboratory.) “Instead, we have an autonomous capability that will be able to receive and interpret commands from the (rover on the) ground, and then fly the mission on its own.”
“The ability to see clearly what lies beyond the next hill is crucial for future explorers,” said Zurbuchen. “We already have great views of Mars from the surface as well as from orbit. With the added dimension of a bird’s-eye view from a ‘marscopter,’ we can only imagine what future missions will achieve.”
Mars 2020 will launch on a United Launch Alliance (ULA) Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida, and is expected to reach Mars in February 2021.
NASA successfully launched the InSight mission to Mars this week. This is a great overview of what scientists will be learning about Martian geology. Read the rest

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...
When the image was taken, Curiosity was partway between its investigation of active sand dunes lower on Mount Sharp, and "Vera Rubin Ridge," a destination uphill where the rover team intends to examine outcrops where hematite has been identified from Mars orbit.
In 1949, pioneering rocket scientist (and Nazi) Wernher von Braun penned a science fiction story called "Project Mars: A Technical Tale" about a human migration to Mars in the 1980s. Turns out though that Mars is already populated by an indigenous civilization led by a government official given the title of... Elon. You'll recall that last year Elon Musk, who is leading the commercial space industry with SpaceX, is very focused on Mars habitation, suggesting we need to get one million people there over the next 50 years. I wonder if Elon is there waiting for Elon. From Project Mars (aka The Mars Project):
The Martian government was directed by ten men, the leader of whom was elected by universal suffrage for five years and entitled "Elon." Two houses of Parliament enacted the laws to be administered by the Elon and his cabinet.
The Upper House was called the Council of the Elders and was limited to a membership of 60 persons, each being appointed for life by the Elon as vacancies occurred by death. In principle, the method was not unlike that by which the College of Cardinals of the Roman Catholic Church is appointed. Usually the Elon chose historians, churchmen, former cabinet members or successful economic leaders who could offer lifetimes of valuable experience.

Jan Fröjdman used HiRISE satellite data from Mars to create this beautiful and detailed flyby of the planet. Liz Stinson writes that stitching it together took months.
For Fröjdman, creating the flyover effect was like assembling a puzzle. He began by colorizing the photographs (HiRISE captures images in grayscale). He then identified distinctive features in each of the anaglyphs—craters, canyons, mountains–and matched them between image pairs. To create the panning 3-D effect, he stitched the images together along his reference points and rendered them as frames in a video. “It was a very slow process,” he says.
When I was a kid, my mind was blown by Isaac Asimov's VHS wonder, Voyage to the Outer Planets and Beyond, which (at least in some versions, if not the one you can find on YouTube), included the NASA Jet Propulsion Lab's 1980s Mars flyover animation: my first encounter with the glitchy, transfixing, uncanny quality of real data from another world. How far we have come, yet not gone.
