Resurrected: Almost 50 years later, Jacksonville man's 1970s recordings still resonateIn 1979 he packed up his unsold albums, moved to Jacksonville with his first wife (he's since remarried), worked in a record store, then started a business. His music, and dreams, were on the shelf. Then... suddenly... they weren't. climate changed from being similar to Earth's to the frozen, barren desert that Curiosity explores today.New type of magnetic wave might explain the strange fluctuations in Earth's magnetic field   Geotail has thus been integral to our understanding of the way energy and matter from the sun affect Earth's neighborhood and how the magnetosphere's magnetic field lines move and rebound while producing explosive bursts that affect our magnetic environment.Hubble Space Telescope and the Gemini-North telescope in Hawaii had revealed the quasar and hinted at a galaxy in a transitional phase.10 amazing exoplanet discoveries "So far this has only been looked at with small samples from Doppler surveys, which typically have found giant planets further away from these red dwarf stars," he said. The salty minerals that enrich this area of Mount Sharp were first spotted by NASA's years before Curiosity touched down on the Martian surface in 2012.  Related Curiosity rover: 15 awe-inspiring photos of Mars (gallery) When Curiosity finally got a close-up look at the terrain of Mount Sharp, the rover discovered a diverse array of rock types and signs of past water, including popcorn-textured nodules and salty minerals such as magnesium sulfate, calcium sulfate (including gypsum) and sodium chloride, which makes up ordinary table salt. The year the spacecraft celebrated its 20th anniversary, in 2012, the first of Geotail's two data recorders failed. After accounting for stresses on the rotary drill at the end of the rover's 7-foot (2 meters) arm that's used to pulverize rock samples for analysis, the Curiosity team selected a rock nicknamed"Canaima" for the drilling and collection of the mission's 36th drill sample. Zakamska, co-principal investigator and Johns Hopkins astrophysicist, said in the same statement. "As we do before every drill, we brushed away the dust and then poked the top surface of Canaima with the drill," Kathya Zamora-Garcia, Curiosity's project manager, said in a statement . After 30 years of continuous operations, the Geotail mission has lasted more than seven times its original length of just four years."The lack of scratch marks or indentations was an indication that it may prove difficult to drill. The team thinks that the lower abundances of heavy elements in the red dwarf star that TOI-3757 b orbits means that the rocky core of this particular exoplanet may have formed more slowly. "  The team then stopped to see whether that posed a danger to Curiosity's arm. "Even a dense knot of dark matter isn't sufficient to explain it," Dominika Wylezalek, an astronomer at Heidelberg University in Germany who led the research, said in a Webb statement . With a new drilling algorithm created to minimize the use of percussion, which is a hammering motion used by drills to penetrate hard surfaces, they decided to proceed, and no percussion was needed, Zamora-Garcia explained.  The team will now analyze pieces of the sample collected from Canaima using Curiosity's Chemical and Mineralogy instrument and Sample Analysis at Mars instrument.

Kanodia and the team then followed up on this initial sighting with a host of ground-based instruments. (Image credit: NASA/JPL-Caltech/MSSS) Curiosity's summer road trip  To reach the sulfate-rich region, the Curiosity rover spent August journeying through a narrow, sand-lined stretch called Paraitepuy Pass. It took over a month for Curiosity to safely navigate this treacherous terrain, which snakes between high hills. Although Paraitepuy Pass is mostly free of sharp rocks that could damage the rover's wheels, sand can be just as hazardous for Curiosity; if its wheels lose traction, the rover could get stuck.  The rover's drivers also had another challenge to consider: The Martian sky was blocked by the hills around it, meaning Curiosity had to be carefully positioned so that its antennas pointed toward Earth and could remain in contact with Mars orbiters.  As the team carefully navigated this path, they were rewarded with some stunning images from Curiosity's Mastcam, particularly a panorama of the region captured on Aug. This makes TOI-3757 b less than half as dense as , which is the lowest-density planet in the solar system and is about one-quarter the density of water. 14. "We would get new images every morning and just be in awe," Curiosity's science operations coordinator, Elena Amador-French, who manages collaboration between the science and engineering teams, said in the statement."The sand ridges were gorgeous. You see perfect little rover tracks on them. And the cliffs were beautiful — we got really close to the walls. " Related stories: .
