Credit: NASA" /></p> <p>NASA's <a href="http://www.nasa.gov/mission_pages/mars/main/">Mars Exploration Program</a> has accomplished some truly spectacular things in the past few decades. Officially launched in 1992, this program has been focused on three major goals: characterizing the climate and geology of Mars, looking for signs of past life, and preparing the way for human crews to explore the planet.</p> <p>And in the coming years, the Mars 2020 rover will be deployed to the Red Planet and become the latest in a long line of robotic rovers sent to the surface. In a recent press release, NASA announced that it has awarded the launch services contract for the mission to <a href="http://www.ulalaunch.com/">United Launch Alliance</a> (ULA) - the makers of the <a href="http://www.ulalaunch.com/products_atlasv.aspx">Atlas V</a> rocket.</p> <p>The mission is scheduled to launch in July of 2020 aboard an Atlas V 541 rocket from Cape Canaveral in Florida, at a point when <a href="http://www.universetoday.com/14824/distance-from-earth-to-mars/">Earth and Mars are at opposition</a>. At this time, the planets will be on the same side of the Sun and making their closest approach to each other in four years, being just 62.1 million km (38.6 million miles) part.</p> <p>Following in the footsteps of the <a href="https://www.nasa.gov/mission_pages/msl/index.html"><em>Curiosity</em></a>, <a href="http://mars.nasa.gov/mer/home/index.html"><em>Opportunity</em></a> and<a href="http://mars.nasa.gov/mer/home/index.html"> <em>Spirit</em></a> rovers, the goal of Mars 2020 mission is to determine the habitability of the Martian environment and search for signs of ancient Martian life. This will include taking samples of soil and rock to learn more about Mars' "watery past".</p> <p>But whereas these and other members of the Mars Exploration Program were searching for evidence that Mars once had liquid water on its surface and a denser atmosphere (i.e. signs that life <em>could</em> have existed), the Mars 2020 mission will attempt to find actual evidence of ancient microbial life.</p> <p>The design of the rover also incorporates several successful features of <em>Curiosity</em>. For instance, the entire landing system (which incorporates a <a href="http://mars.jpl.nasa.gov/mars2020/multimedia/images/?ImageID=3650">sky crane</a> and heat shield) and the rover's chassis have been recreated using leftover parts that were originally intended for <em>Curiosity</em>.</p> <p>There's also the rover's radioisotope thermoelectric generator - i.e. the nuclear motor - which was also originally intended as a backup part for <i>Curiosity. </i>But it will also have several upgraded instrument on board that allow for a new guidance and control technique. Known as "Terrain Relative Navigation", this new landing method allows for greater maneuverability during descent.</p> <p>Another new feature is the rover's drill system, which will collect core samples and store them in sealed tubes. These tubes will then be left in a "cache" on the surface, where they will be retrieved by future missions and brought back to Earth - which will constitute the first sample-return mission from the Red Planet.</p> <p>In this respect, Mars 2020 will help pave the way for a crewed mission to the Red Planet, which NASA hopes to mount sometime in the 2030s. The probe will also conduct numerous studies designed to improve landing techniques and assess the planet's natural resources and hazards, as well as coming up with methods to allow astronauts to live off the environment.</p> <p>In terms of hazards, the probe will be looking at Martian weather patterns, dust storms, and other potential environmental conditions that will affect human astronauts living and working on the surface. It will also test out a method for producing oxygen from the Martian atmosphere and identifying sources of subsurface water (as a source of drinking water, oxygen, and hydrogen fuel).</p> <p>As NASA stated in their <a href="http://www.nasa.gov/press-release/nasa-awards-launch-services-contract-for-mars-2020-rover-mission">press release</a>, the Mars 2020 mission will "offer opportunities to deploy new capabilities developed through investments by NASA's Space Technology Program and Human Exploration and Operations Mission Directorate, as well as contributions from international partners."</p> <p>They also emphasized the opportunities to learn ho future human explorers could rely on in-situ resource utilization as a way of reducing the amount of materials needed to be shipped - which will not only cut down on launch costs but ensure that future missions to the planet are more self-reliant.</p> <p>The total cost for NASA to launch Mars 2020 is approximately $243 million. This assessment includes the cost of launch services, processing costs for the spacecraft and its power source, launch vehicle integration and tracking, data and telemetry support.</p> <p>The use of spare parts has also meant reduced expenditure on the overall mission. In total, the Mars 2020 rover and its launch will cost and estimated $2.1 billion USD, which represents a significant savings over previous missions like the <a href="http://mars.nasa.gov/msl/">Mars Science Laboratory</a> - which cost a total of $2.5 billion USD.</p> <p>Between now and 2020, NASA also intends to launch the <a href="http://solarsystem.nasa.gov/insight/home.cfm">Interior Exploration using Seismic Investigations, Geodesy and Heat Transport</a> (InSight) lander mission, which is currently targeted for 2018. This and the Mars 2020 rover will be the latest in a long line of orbiters, rovers and landers that are seeking to unlock the mysteries of the Red Planet and prepare it for human visitors!</p> <p><em>Further Reading: <a href="http://www.nasa.gov/press-release/nasa-awards-launch-services-contract-for-mars-2020-rover-mission">NASA</a></em>, <a href="http://mars.nasa.gov/mars2020/mission/overview/"><em>Mars 2020 Rover</em></a></p> <p>The post <a rel="nofollow" href="http://www.universetoday.com/130500/nasa-goes-atlas-v-launch-mars-2020-rover/">NASA Goes With Atlas V To Launch Mars 2020 Rover</a> appeared first on <a rel="nofollow" href="http://www.universetoday.com">Universe Today</a>.</p>

It also marks the first time that the entire suite of nine state-of-the-art science instruments had been turned on to gather the totally unique observations of Jupiter’s interior and exterior environment. </p> <p>"We are getting some intriguing early data returns as we speak," said Scott Bolton, principal investigator of Juno from the Southwest Research Institute in San Antonio, in a statement. </p> <p>"This is our first opportunity to really take a close-up look at the king of our solar system and begin to figure out how he works." </p> <p>Additional up-close high resolution imagery of the Jovian atmosphere, swirling cloud tops and north and south poles snapped by JunoCam will be released in the coming weeks, perhaps as soon as next week.</p> <p>"We are in an orbit nobody has ever been in before, and these images give us a whole new perspective on this gas-giant world," said Bolton. </p> <p>"It will take days for all the science data collected during the flyby to be downlinked and even more to begin to comprehend what Juno and Jupiter are trying to tell us."</p> <p>The prime mission is scheduled to end in February of 2018 with a suicide plunge into the Jovian atmosphere to prevent any possible contamination with Jupiter’s potentially habitable moons such as Europa and Ganymede.</p> <p>"No other spacecraft has ever orbited Jupiter this closely, or over the poles in this fashion," said Steve Levin, Juno project scientist from NASA's Jet Propulsion Laboratory in Pasadena, California. "This is our first opportunity and there are bound to be surprises. We need to take our time to make sure our conclusions are correct." </p> <p>The team did release an approach image taken by JunoCam on Aug. 23 when the spacecraft was 2.8 million miles (4.4 million kilometers) from the gas giant planet on the inbound leg of its initial 53.5-day capture orbit.</p> <p>One additional long period orbit is planned. The main engine will fire again in October to reduce the orbit to the 14 day science orbit. </p> <p>The solar powered probe will collect unparalleled new data that will unveil the hidden inner secrets of Jupiter’s origin and evolution as it peers “beneath the obscuring cloud cover of Jupiter and study its auroras to learn more about the planet's origins, structure, atmosphere and magnetosphere.”</p> <p><a href="http://www.universetoday.com/87976/juno-blasts-off-on-science-trek-to-discover-jupiters-genesis/">The $1.1 Billion Juno was launched on Aug. 5, 2011</a> from Cape Canaveral Air Force Station, Florida atop the most powerful version of the Atlas V rocket augmented by 5 solid rocket boosters and built by United Launch Alliance (ULA).

The movie begins on June 12th with Juno 10 million miles from Jupiter, and ends on June 29th, 3 million miles distant. The innermost moon is volcanic Io; next in line is the ice-crusted ocean world Europa, followed by massive Ganymede, and finally, heavily cratered Callisto. Galileo observed these moons to change position with respect to Jupiter over the course of a few nights. From this observation he realized that the moons were orbiting mighty Jupiter, a truth that forever changed humanity's understanding of our place in the cosmos. Earth was not the center of the Universe. For the first time in history, we look upon these moons as they orbit Jupiter and share in Galileo’s revelation. This is the motion of nature's harmony.
