Above, one of the last images taken by the Mars rover Spirit (NASA/JPL/Cornell).
NASA this week announced it will cease attempts to re-establish contact with the Mars Exploration Rover "Spirit," which last communicated on March 22, 2010. From an item on the Space Coalition website:
The stuck in the sand Mars rover reached a point where there was inadequate energy to run its survival heaters. That being the case, the rover likely experienced colder internal temperatures last year than in any of its prior six years on Mars. Many critical components and connections would have been susceptible to damage from the cold. Today, a transmission from Earth will be the last in a series of attempts to reawaken the robot.
Spirit drove 4.8 miles (7.73 kilometers), more than 12 times the goal set for the mission. The drives crossed a plain to reach a distant range of hills that appeared as mere bumps on the horizon from the landing site; climbed slopes up to 30 degrees as Spirit became the first robot to summit a hill on another planet; and covered more than half a mile (nearly a kilometer) after Spirit's right-front wheel became immobile in 2006. The rover returned more than 124,000 images. It ground the surfaces off 15 rock targets and scoured 92 targets with a brush to prepare the targets for inspection with spectrometers and a microscopic imager.
New research on trends in adult human height over the last century confirm that, no surprise, humans are getting taller overall due to better nutrition and disease control. However according to the health science group Non-Communicable Diseases Risk Factor Collaboration (NCD-RisC), the gain in adult height varies dramatically by country. From their paper, published in […]
Between April and July, Iran’s salty Lake Urmia changed from a bright green color to a blood red. NASA’s Aqua satellite captured the image above and reported on the science behind the strange transformation. According to NASA, the periodic color change is caused by micro algae producing carotenoids that help with photosynthesis and act as […]
In the late 1960s and 1970s, the mind-expanding modus operandi of the counterculture spread into the realm of science, and shit got wonderfully weird. Neurophysiologist John Lilly tried to talk with dolphins. Physicist Peter Phillips launched a parapsychology lab at Washington University. Princeton physicist Gerard O’Neill became an evangelist for space colonies. Groovy Science: Knowledge, […]
