 Nasa exploring alternative ways to bring sample of Mars to earth,as a part of Mars sample returning program.these samples are collected by  Perseverance rover  from 2021 to send them to earth for further studies Credit : nasa In that process Nasa conducting about 10 studies to find fast and reliable way to bring sample back to earth.as a effort of that Nasa will award about $1.5 millon to seven proposers for 90 days studies Additionally Nasa centers,NASA's JBL of california etc are also in studies.once all these studies are completed,Nasa will consider all studies to make modifications to Mars sample bringing plan “Mars Sample Return will be one of the most complex missions NASA has undertaken, and it is critical that we carry it out more quickly, with less risk, and at a lower cost,”. “I’m excited to see the vision that these companies, centers and partners present as we look for fresh, exciting, and innovative ideas to uncover great cosmic secrets from the Red Planet.”s

 Nasa 's curiosity rower is still in martian surface and currently exploring the planet.it has reached a fascinating rock formation dubbed "Rocky road" or "convict lake" It is 'Rocky road' or 'convict lake'.This image capture by curiosity rover on Mars surface using its MAHLI instrument.on June 4 2024 Because of its unique apperance.rovers primary aim is to analyse the rock using its advanced instruments to gain knowledge about martian surface Tests and analysis done by rover: APXS analysis   The alpha particle x-ray spectrometer(APXS) is used to examine the chemical composition.The team of curiosity rover tried to position the APXS as possible as near to rock to collect data of its elemental makeup.The goal is to target the areas with a 'marshmallow' ratio,which indicates specific  balance of elements ChemCam investigation   The chemical and camera (chemcam) instrument also used to study the rock.the laser in the instrument vaporiz
