Mars Advanced Radar for Subsurface and Ionosphere Sounding

Contents

Mars Advanced Radar for Subsurface and Ionosphere Sounding is a NASA-funded instrument onboard the European Space Agency's Mars Express spacecraft, which was launched by a Soyuz-FG rocket from the Baikonur Cosmodrome in Kazakhstan. The Mars Express mission is a collaborative effort between the European Space Agency, NASA, and the Italian Space Agency, with significant contributions from Canada, France, Germany, Japan, Russia, and the United Kingdom. The primary goal of the Mars Express mission is to study the planet Mars using a combination of orbiter and lander spacecraft, including the Beagle 2 lander, which was designed and built by the University of Leicester and the Open University.

Introduction

The Mars Advanced Radar for Subsurface and Ionosphere Sounding is a radar instrument designed to study the subsurface of Mars and its ionosphere. The instrument uses a combination of pulse and continuous wave radar techniques to penetrate the Martian surface and gather data on the subsurface structure and composition, including the presence of water ice and liquid water. The Mars Advanced Radar for Subsurface and Ionosphere Sounding is similar to other radar instruments used in space exploration, such as the Cassini radar instrument used to study the moons of Saturn, including Titan and Enceladus. The Mars Advanced Radar for Subsurface and Ionosphere Sounding has also been compared to the SHARAD radar instrument onboard the NASA Mars Reconnaissance Orbiter, which has been used to study the polar ice caps of Mars and the geology of the Martian surface.

The Mars Advanced Radar for Subsurface and Ionosphere Sounding instrument consists of a radar antenna and a receiver system designed to detect and analyze the radar signals reflected from the Martian surface and subsurface. The instrument operates at a frequency of 20 MHz and has a bandwidth of 10 MHz, allowing it to penetrate the Martian surface to a depth of several kilometers. The Mars Advanced Radar for Subsurface and Ionosphere Sounding is similar to other radar instruments used in geophysical research, such as the Ground-Penetrating Radar instrument used to study the subsurface of the Earth. The Mars Advanced Radar for Subsurface and Ionosphere Sounding has been used in conjunction with other instruments onboard the Mars Express spacecraft, including the Mars Express Orbiter's HRSC camera and the OMEGA spectrometer, to gather data on the geology and composition of the Martian surface.

The primary scientific objectives of the Mars Advanced Radar for Subsurface and Ionosphere Sounding are to study the subsurface of Mars and its ionosphere. The instrument is designed to gather data on the distribution and abundance of water ice and liquid water in the Martian subsurface, as well as the structure and composition of the Martian crust. The Mars Advanced Radar for Subsurface and Ionosphere Sounding has also been used to study the ionosphere of Mars, including the density and composition of the ionospheric plasma. The instrument has been used in conjunction with other instruments onboard the Mars Express spacecraft, including the ASPERA instrument and the MaRS instrument, to gather data on the atmosphere and climate of Mars. The Mars Advanced Radar for Subsurface and Ionosphere Sounding has also been compared to other radar instruments used in space exploration, such as the Magellan radar instrument used to study the surface of Venus.

The Mars Advanced Radar for Subsurface and Ionosphere Sounding instrument is operated by the European Space Agency's European Space Operations Centre in Darmstadt, Germany. The instrument is powered by the Mars Express spacecraft's solar panels and has a mass of approximately 10 kg. The Mars Advanced Radar for Subsurface and Ionosphere Sounding has a data rate of approximately 100 kbps and transmits data to the European Space Agency's ground station in Cebreros, Spain. The instrument has been used in conjunction with other instruments onboard the Mars Express spacecraft, including the PFS instrument and the SPICAM instrument, to gather data on the atmosphere and climate of Mars. The Mars Advanced Radar for Subsurface and Ionosphere Sounding has also been compared to other radar instruments used in space exploration, such as the Cassini radar instrument used to study the moons of Saturn.

The Mars Advanced Radar for Subsurface and Ionosphere Sounding instrument was launched onboard the Mars Express spacecraft on June 2, 2003, from the Baikonur Cosmodrome in Kazakhstan. The instrument began operating in December 2003 and has been used to gather data on the subsurface of Mars and its ionosphere. The Mars Advanced Radar for Subsurface and Ionosphere Sounding has been used in conjunction with other instruments onboard the Mars Express spacecraft, including the HRSC camera and the OMEGA spectrometer, to gather data on the geology and composition of the Martian surface. The Mars Advanced Radar for Subsurface and Ionosphere Sounding has also been compared to other radar instruments used in space exploration, such as the SHARAD radar instrument onboard the NASA Mars Reconnaissance Orbiter. The Mars Express mission has been extended several times, including an extension to 2014 and another to 2016, and the Mars Advanced Radar for Subsurface and Ionosphere Sounding continues to operate and gather data on the subsurface of Mars and its ionosphere.
