<jats:title>Going to Mars</jats:title> <jats:p> The Mars Science Laboratory spacecraft containing the Curiosity rover, was launched from Earth in November 2011 and arrived at Gale crater on Mars in August 2012. <jats:bold> Zeitlin <jats:italic>et al.</jats:italic> </jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6136" page="1080" related-article-type="in-this-issue" vol="340" xlink:href="10.1126/science.1235989">1080</jats:related-article> ) report measurements of the energetic particle radiation environment inside the spacecraft during its cruise to Mars, confirming the hazard likely to be posed by this radiation to astronauts on a future potential trip to Mars. <jats:bold> Williams <jats:italic>et al.</jats:italic> </jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6136" page="1068" related-article-type="in-this-issue" vol="340" xlink:href="10.1126/science.1237317">1068</jats:related-article> , see the Perspective by <jats:bold> <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6136" page="1055" related-article-type="in-this-issue" vol="340" xlink:href="10.1126/science.1239343">Jerolmack</jats:related-article> </jats:bold> ) report the detection of sedimentary conglomerates (pebbles mixed with sand and turned to rock) at Gale crater. The rounding of the rocks suggests abrasion of the pebbles as they were transported by flowing water several kilometers or more from their source. </jats:p>
