    NASA's Opportunity rover, the third robotic wanderer to land on Mars, changed our understanding of the Martian landscape, geology, atmosphere and history. On Wednesday, NASA announced its mission complete and with it, the rover's life officially over. The plucky robot roamed the Martian surface for approximately 5,515 Earth days, just over 15 years. During a press conference, NASA said that Opportunity hadn't responded to a last-ditch effort Tuesday to establish contact. A planet-encircling dust storm cut off communications with Opportunity on June 10, 2018, preventing its solar panels from storing power. Since then, over 830 rescue commands had been beamed...
  • Strange crescent-shaped pit near Martian south pole

    Cool image time! The south polar cap of Mars is a strange place. It is largely ice, with a seasonal cap of frozen carbon dioxide, or dry ice. Because the dry ice sublimates away during the summer months, the cap undergoes regular changes that reshape it, producing alien features that are not seen on Earth. The image on the right is another example of these alien features. I found it in the February image release from the high resolution camera on Mars Reconnaissance Orbiter. I have merely cropped the full image to focus at full resolution on its primary feature,...
  • Mysterious dark-toned Martian terrain

    Cool image time! The picture on the right, cropped and reduced to post here, was part of the January image release from the high resolution camera of Mars Reconnaissance Orbiter (MRO). It shows an area in the Martian southern highlands where the surface suddenly gets darker, for no obvious reason. The uncaptioned release image is titled “Dark-Toned Ridge at Junction with Dark-Toned Plain.” From the image itself it is hard to understand this title. In the full image the darkest terrain is a strip in the center, with slightly lighter dark terrain on either side, and the lightest terrain to...

    On the night of the new moon itself, observers in midnorthern latitudes will see the classic winter constellations of Orion, Taurus, Gemini and Canis Major for most of the night. All of these constellations will be above the horizon by 7 p.m. local time. Orion's distinctive belt of three stars — Alnilam, Alnitak and Mintaka — will be at an altitude of about 40 degrees in the south-southeast, while Sirius, the brightest star in the sky, will be about 21 degrees high. Looking just to the east and south of Orion (to the right and upward in the northern hemisphere),...

    The robotic drone is performing classified duties during the program’s fifth flight. The current mission — known as Orbital Test Vehicle (OTV-5) — was rocketed into Earth orbit on Sept. 7, 2017, atop a SpaceX Falcon 9 booster from Launch Complex 39A at NASA’s Kennedy Space Center (KSC) in Florida.

  • U.S. Refiners Rush To Buy Heavy Oil As Trump Looks To Punish Maduro

    Refiners in the United States are stocking up on heavy crude, pushing prices higher, as the Trump administration prepares to slam more punitive measures on Caracas after the inauguration of Nicolas Maduro as president of Venezuela for a second term after elections considered illegitimate by Washington. Reuters reports that officials from the presidential administration met with oil industry executives to discuss the measures on the table, including the suspension ofrefined product exports to Venezuela or Venezuelan crude oil imports into the United States. Gulf Coast refiners have a limited choice of supplier when it comes to heavy crude. Besides local...

    Engineers haven't heard from the beleaguered robot since June 10, 2018, shortly before a global dust storm developed on Mars. The Opportunity rover, which is solar-powered, has ignored hundreds of calls from Earth since it first fell silent, which made team members worry that its mission has come to an end. As the silence stretched on over the summer, mission members hoped that the storm had simply dropped dust on the solar panels that power Opportunity and that a natural seasonal weather phenomenon on Mars could clear that dust away, letting the rover recharge.... That hope led the team to...

    Full Title: "Fresh blow for Mars missions as researchers find long-duration space travel causes crippling back pain that can last for up to four YEARS" The changes in muscle composition are still present up to four years after long-duration spaceflight, according to the new research by Katelyn Burkhart, MS, of Massachusetts Institute of Technology and colleagues. They write, 'Spaceflight-induced changes in paraspinal muscle morphology may contribute to back pain commonly reported in astronauts.' The researchers analyzed computed tomography (CT) scans of the lumbar (lower) spine in 17 astronauts and cosmonauts who flew missions on the International Space Station. Scans obtained...

    While the team found that the bacteria isolated from the ISS did contain different genes than their Earthling counterparts, those genes did not make the bacteria more detrimental to human health. The bacteria are instead simply responding, and perhaps evolving, to survive in a stressful environment. As the conversation about sending travelers to Mars gets more serious, there has been an increasing interest in understanding how microbes behave in enclosed environments. "People will be in little capsules where they cannot open windows, go outside or circulate the air for long periods of time," said Hartmann. "We're genuinely concerned about how...
  • NASA's Mars 2020 Rover Is Unique. And So Is Its Paint Job.

    Before NASA's Mars 2020 mission is ready to launch toward the Red Planet, the agency has to paint the new rover — a task more challenging than it sounds. While a paint job may sound like an insignificant task, both the formulation and the process of painting a spacecraft like this have to be precise. And each spacecraft is unique. In August 2018, engineers working on the rover's chassis (the frame of the spacecraft) started the first step in the painting process: taping. Parts of the rover must never be painted, such as places where electronics boxes will eventually go...

    Sending astronauts to Mars would be stupid, says ApolOne of the first astronauts to orbit the Moon said on Wednesday that it's "stupid" to plan human missions to Mars. Bill Anders, who was the lunar module pilot for NASA's Apollo 8 mission, told BBC Radio 5 Live that sending crews to the Red Planet would be "almost ridiculous." The U.S. space agency's goals include sending humans to Mars for exploration and scientific study. "What's the imperative? What's pushing us to go to Mars?" Anders, 85, said, adding: "I don't think the public is that interested." Still, the retired astronaut did...

    It is a picture perfect Christmas card image from another planet. The European Space Agency's Mars Express has returned an incredible new series of images showing a giant crater on the red planet. It shows the Korolev crater, a 50 mile (82 km) wide feature in in the northern lowlands of Mars. Just south of a large patch of dune-filled terrain that encircles part of the planet's northern polar cap (known as Olympia Undae), ESA says it is 'an especially well-preserved example of a martian crater.' It is filled not by snow but ice, with its center hosting a mound...
  • InSight Records Sound of Wind on Mars

    On December 1, 2018, NASA’s InSight lander captured a haunting low rumble caused by vibrations from the Martian wind, estimated to be blowing between 10 to 15 mph (5-7 m/sec) from northwest to southeast. The wind was consistent with the direction of dust devil streaks in the landing area, which were observed from orbit. “Capturing this audio was an unplanned treat. But one of the things our mission is dedicated to is measuring motion on Mars, and naturally that includes motion caused by sound waves,” said InSight principal investigator Dr. Bruce Banerdt, a researcher at NASA’s Jet Propulsion Laboratory.The vibrations...

    NASA’s spacecraft that landed on Mars on Monday has beamed back its first clear photo of the desolate Red Planet. “There’s a quiet beauty here. Looking forward to exploring my new home,” NASA tweeted late Monday, hours after its new InSight lander touched down. The image came after the rover had earlier sent back a somewhat blurry photo. The space agency said that in the interim, the spacecraft had opened its solar panels, which allowed it to recharge its batteries for the mission.

    A Russian astronomer observed the planets thru a telescope made of ice. Henry describes his observations. Ever wondered what the opinion of equality of the sexes was in 1789? Henry's position is that "Love, and all its delectable concomitants was utterly unknown there [on Venus]; as that passion exists but where equality is found or understood." Interesting?

    The target of Curiosity's curiosity is nicknamed "Little Colonsay" and it looks like a small nugget. The rover's ChemCam captured a close-up view of the object on Monday. "The planning team thinks it might be a meteorite because it is so shiny," writes Curiosity team member Susanne Schwenzer. "But looks can deceive, and proof will only come from the chemistry." uriosity's ChemCam is a suite of instruments that includes a camera, spectographs and a laser that helps NASA analyze the composition of Martian rocks and soil. The rover is scheduled to investigate Little Colonsay with the ChemCam to determine if...

    The Martian was one of the biggest hits of 2015, and was nominated for tons of year-end awards. But being as it's set in space and in the near future, we thought it best to bring back Dr. Neil deGrasse Tyson to help us separate this movie's sins from its wins.
