CNN —Data from a retired NASA mission has revealed evidence of an underground reservoir of water deep beneath the surface of Mars, according to new research. A team of scientists estimates that there may be enough water, trapped in tiny cracks and pores of rock in the middle of the Martian crust, to fill oceans on the planet’s surface. NASA's Mars Reconnaissance Orbiter took an image of InSight sitting on the Martian surface on February 2, 2019. “It’s certainly true on Earth — deep, deep mines host life, the bottom of the ocean hosts life. Windows into Martian historyThe findings add a new piece to the Martian water puzzle.

CNN —Hundreds of basketball-size space rocks slam into Mars each year, leaving behind impact craters and causing rumblings across the red planet, according to new research. During its time on Mars, InSight used its seismometer to detect more than 1,300 marsquakes, which take place when the Martian subsurface cracks due to pressure and heat. Meteoroids are space rocks that have broken away from larger rocky bodies and range in size from dust grains to small asteroids, according to NASA. “We’re interested in studying that on Mars because we can then compare and contrast what’s happening on Mars to what’s happening on the Earth. Between 280 and 360 meteoroids hit the red planet each year, and they form impact craters larger than 26 feet (8 meters) across, according to the study.

☆ A mysterious hole on Mars could be a jackpot of scientific discoveries, from extraterrestrial life to where astronauts could live

But there is a possibility that residual underground lava tubes may still exist. HUM Images/Getty ImagesIf these lava tubes are anything like Earth's, they could be the perfect place for astronauts to hunker down during their stay on Mars. It's unclear if lava tubes on Mars would also be this warm — it's not a stretch to imagine, just a challenge to confirm. But to be clear, just because there could be life in these pits, doesn't mean Mars definitely hosts extraterrestrials. "This is a good place to look, but we don't know if there's life on Mars at all," Johnson said.

☆ Mars volcano the size of Mount Everest was hiding in plain sight, report says

CNN —Scientists may have pinpointed a massive, oddly shaped volcano taller than Mount Everest on the surface of Mars — and it has been hiding in plain sight for decades, according to new research. Some of the largest volcanoes on Mars lie relatively close to the proposed “Noctis volcano.” Shown here: 1) Olympus Mons, the tallest known volcano in our solar system. This NASA visualization of the Tharsis rise shows Olympus Mons, Tharsis Montes, Noctis Labyrinthus, and Valles Marineris. NASA SVSA volcano, a glacier and the history of MarsThe existence of a volcano in Noctis Labyrinthus could also help explain the creation of this bizarre landscape. The existence of a volcano in the region, Lee said, might offer more support for the latter theory.

☆ Solar conjunction halts communications between Mars missions and NASA
▼ + stars: | 2023-11-15 | by ( Ashley Strickland | ) edition.cnn.com time to read: +4 min

CNN —Robotic explorers investigating Mars are currently out of touch with space agencies on Earth after hitting a giant communications roadblock. Mission controllers at NASA won’t send any commands to its fleet of orbiters and rovers, including Perseverance and Curiosity, for the next 10 days due to the Mars solar conjunction. During the roughly two-week period, the hot, energized gas continually spewed by the sun from its outer atmosphere can interfere with the radio signals that NASA uses to communicate with its Martian robotic explorers. A Mars solar conjunction occurs every two years when the sun moves between Mars and Earth. The Ingenuity helicopter, which has largely served as the Perseverance rover’s aerial scout, will also lie low and won’t conduct any flights during this time.

☆ NASA imagery reveals China's Mars rover hasn't moved in months as Chinese scientists scramble to save the mission

NASA imagery from Mars shows that China's rover hasn't moved in months. Chinese scientists are scrambling to make contact, according to the South China Morning Post. China's rover, Zhurong, could be covered in dust and drained of energy, like NASA's InSight lander. Arrows highlight the location of China's Zhurong rover in March 2022, September 2022, and February 2023.

The picture looks like a giant bear. NASA has spotted several other amusing rock formations on Mars over the years. The Mars Reconnaissance Orbiter, a satellite launched in 2005, has provided groundbreaking science on its mission. The most iconic example of pareidolia is the "Face on Mars," a picture snapped in 1976 by NASA's Viking 1 spacecraft. NASA's iconic "face on Mars" picture snapped by Viking-1 in 1976.

☆ Mars may have molten lava, scientists discover from quakes detected by NASA's Insight lander

NASA's InSight lander has detected Mars quakes that mostly come from one region: Cerberus Fossae. But now, using a seismometer on NASA's InSight lander, scientists have discovered the first evidence of molten lava deep below the Martian surface. A series of Mars quakes clued the scientists in to the potential lava hotspot. The biggest Mars quakes point to an underground chamber of magmaInSight has detected more than 1,300 Mars quakes since landing on the red planet in 2018. To get the global picture of Mars quakes and volcanic activity, NASA would need to send more seismometers to the red planet.

NASA's InSight lander felt a powerful Mars quake. Then an orbiter took a picture of the meteor impact that caused it. The impact kicked up boulders of water ice, which will be crucial for future astronaut missions to Mars. "It was immediately clear that this is the biggest new crater we've ever seen," Ingrid Daubar, InSight impact science lead, said in a press briefing.

Camera HiRISE de la bordul navetei MRO a realizat cadrele pe 6 iunie, la trei săptămâni după ce Zhurong a asolizat pe Marte. China a devenit a doua țară din lume după Statele Unite care își plasează un rover pe suprafața planetei Marte, după amartizarea cu succes a robotului Zhurong. Roverul a fost trimis cu misiunea Tianwen-1, care a fost lansată spre Marte în iulie 2020. Misiunea cuprinde și o navetă care orbitează în jurul planeteo Marte și folosește pe post de antenă de comunicații între Zhurong și Pământ.
