    NASA's InSight lander 'hears' Martian wind

    NASA's InSight lander, which touched down on Mars on November 26, has provided the first ever "sounds" of Martian wind on the Red Planet, the NASA said.InSight sensors captured a haunting low rumble caused by vibrations from the wind, estimated to be blowing between 10 to 15 mph (5 to 7 metres a second) on December 1, from northwest to southeast, NASA said on Friday. Citing NASA, Xinhua news agency reported the winds were consistent with the direction of dust devil streaks in the landing area, which were observed from orbit. "Capturing this audio was an unplanned treat," said Bruce Banerdt, InSight principal investigator at NASA's Jet Propulsion Laboratory in Pasadena, California. "But one of the things our mission is dedicated to is measuring motion on Mars, and naturally that includes motion caused by sound waves." According to NASA, two very sensitive sensors on the spacecraft detected these wind vibrations: an air pressure sensor inside the lander and a seismometer sitting on the lander's deck, awaiting deployment by InSight's robotic arm. The two instruments recorded the wind noise in different ways. The air pressure sensor, which will collect meteorological data, recorded these air vibrations directly. The seismometer recorded lander vibrations caused by the wind moving over the spacecraft's solar panels, which are each 7 feet (2.2 metres) in diameter and stick out from the sides of the lander like a giant pair of ears. This is the only phase of the mission during which the seismometer, called the Seismic Experiment for Interior Structure (SEIS), will be capable of detecting vibrations generated directly by the lander, said NASA. In a few weeks, it will be placed on the Martian surface by InSight's robotic arm, then covered by a domed shield to protect it from wind and temperature changes. It will detect the lander's movement through the Martian surface, said NASA. SEIS is recording vibrational data that scientists later will be able to use to cancel out noise from the lander when SEIS is on the surface, allowing them to detect better actual marsquakes. InSight landed safely at Elysium Planitia on Mars on November 26, kicking off a two-year mission to explore the deep interior of the Red Planet.

    NASA's Kepler telescope bids 'goodbye' with final commands

    NASA's popular Kepler space telescope has put itself into rest mode after getting the final commands from the Earth. The telescope has discovered thousands of planets outside our solar system and revealed that our galaxy contains more planets than stars. Here's now that it has received its final set of commands to disconnect communications with Earth. And, it’s the “goodnight” commands which finalise the spacecraft’s transition into retirement.

    New 'super-earth' discovered orbiting star nearest to Sun

    In an attempt to explore the sky, astronomers have discovered a frozen planet which weighs three times the earth. It is orbiting the closest solitary star to the Sun and scientists termed it as 'Super Earth'. Read the article to know about this strange rocky planet which orbits around its host star once every 233 days.

    China's artificial sun may develop clean energy. It's amazingly hot

    While China is known for designing artificial celestial bodies, its new artificial sun has become the talk of global town. It’s been a few weeks that we learnt that experts in the country was making a fake moon, now we came to know that it’s an earth-based sun simulator which is producing temperatures of 100 million degrees Celsius.
