NASA plans careful restart for Mars helicopter after quiet period

NASA plans careful restart for Mars helicopter after quiet period

Science
Oct. 1 (UPI) -- The Mars helicopter Ingenuity is on its own without NASA's guidance for two weeks as the sun interferes with communications to the Red Planet. Sometime around Oct. 14, NASA plans to check in with the helicopter and the Mars rover Perseverance. Previous rovers have endured so-called solar conjunction communication dropouts, but never has a tiny aircraft sat alone on the planet for so long with no Earthly contact. "Ingenuity is unique, something never tried before," Jaakko Karras, Ingenuity deputy operations lead, told UPI. "It contains all kinds of components and construction methodologies that have no parallel on Mars. We just don't know what will happen during the conjunction, although we're hopeful," Karras said. Potential hazards during conjunction include ...
Ocean noise: Study to measure the oceans’ ‘year of quiet’

Ocean noise: Study to measure the oceans’ ‘year of quiet’

Science
AlamyOcean scientists around the world are studying the "unique moment" of quiet created by the pandemic. The researchers have called their vast listening experiment: The year of the quiet ocean. "Lockdown slowed global shipping on a scale that would otherwise be impossible," explained Prof Peter Tyack from the University of St Andrews. The scientists plan to listen to the ocean soundscape before, during and after lockdown. They have identified 200 ocean hydrophones - underwater microphones that are already in place around the global ocean. "So the idea is to use those to measure the changes in noise and how they affect marine life - like calling whales or fish choruses," Prof Tyack said. "Just like people and cities may have noticed that, with much less traffic noise and human activity, ...

The Latest on WikiLeaks founder Julian Assange (all times local): 11:10 a.m. Media are assembled outside the Ecuadorian Embassy in London after tweets from WikiLeaks quoted sources saying that Julian Assange could be kicked out of the building within "hours to days." The red-brick embassy building with white window frames and balconies was quiet Friday, but armed British police officers were stationed outside. No embassy official or any British authorities have commented. Assange hasn't left the embassy since August 2012, fearing if he steps off Ecuador's diplomatic soil he will be arrested and extradited to the U.S. for publishing thousands of classified military and diplomatic cables through WikiLeaks. Ecuador's foreign ministry issued a statement late Thursday saying it wouldn't commen...
Scientists unsure when Hawaii's Kilauea volcano will quiet

Scientists unsure when Hawaii's Kilauea volcano will quiet

Technology
Experts remained flummoxed Friday about when Hawaii's Kilauea volcano will calm down. The Big Island volcano exploded at its summit Thursday, sending ash and rocks thousands of feet into the sky. Scientists said the eruption was the most powerful in recent days, though it probably lasted only a few minutes. It came two weeks after the volcano began sending lava flows into neighborhoods 25 miles (40 kilometers) to the east of the summit, destroying 26 homes. On Friday, Hawaii County officials warned residents that fast-moving lava was approaching an area east of those destroyed homes. Hawaii County Civil Defense said police, firefighters and National Guard troops were securing the area and stopping people from entering. About 40 homes in the area are now isolated. Earlier in the day, a ne...
