EXOMARS is a European-led space exploration mission, currently under development by the European Space Agency (ESA) that will send a robotic rover to the surface of Mars. The EXOMARS rover is a “robotic mission” which will provide Europe with new technologies for the exploration of Mars, specifically the surface Rover and its Drill and Sample Preparation and Distribution System (SPDS). ...The scientific payloads are accommodated in two separate assemblies: the Pasteur Payload installed onboard the Rover, and the Geophysical Science Package, mounted on the Landing Platform. The Rover accommodates as well a drill capable of collecting soil samples down to 2 m below the Mars surface. ...The EXOMARS rover is a “robotic mission” which will provide Europe with new technologies for the exploration of Mars, specifically the surface Rover and its Drill and Sample Preparation and Distribution System (SPDS). The EXOMARS spacecraft will be launched from the Guiana Space Centre (Kourou) in 2013: it will consist of the Carrier Module (CM) and a Descent Module (DM).
The Mars Rover has a lightweight integrated structure/insulation that has been environmentally tested and qualified for the 1996 launch for the Pathfinder mission to Mars. ...The basic structure with insulation, called the Warm Electronics Box (WEB), accounts for only 10% of the total Rover mass. The WEB is a thermal isolating composite structure with co-cured thermal control surfaces and an ultralightweight hydrophobic solid silica aerogel which minimizes conduction and radiation. ...This design provides excellent thermal insulation at low gas pressures and meets the structural requirements for spacecraft launch loads and for a 60 g impact landing at Mars without damage to the insulation or structure. The Rover design has been thermally qualified in a series of both static and transient thermal-vacuum testing in vacuum and 8 torr wind environments simulating all predicted environmental conditions.
The general goal of the mission is part lunar science as well as technology demonstration which are not limited to the Moon. The Rover element of the mission is composed of the rover vehicle service model element, locomotion system and the science payload, with a significant constraint on the overall mass. ...The Moon-NEXT Lunar Rover is the mobile component of a lunar lander mission to provide the best possible in situ science and mobility in the area of the Lunar south pole. ...The lunar thermal environment presents the main challenge to autonomous rover thermal design at the selected landing site. A primary goal of the mission is to operate in the polar region of the Moon, in a territory that may support future a manned base.
During each launch opportunity, the missions to Mars will include a Rover mission. During the earlier Rover missions to Mars such as the Mars Pathfinder mission carrying the Sojourner Rover in 1997, the main rover power source was a solar array. ...During the earlier Rover missions to Mars such as the Mars Pathfinder mission carrying the Sojourner Rover in 1997, the main rover power source was a solar array. The power subsystem of the Sojourner Rover included a solar panel for power during the day, a non-rechargeable lithium battery for power during the night, and a power electronics board for power conditioning and distribution. ...The power subsystem of the Sojourner Rover included a solar panel for power during the day, a non-rechargeable lithium battery for power during the night, and a power electronics board for power conditioning and distribution.
The ground experiments are carried on a wheeled Mars Rover vehicle, which comprises a service module and the 40kg Pasteur payload module containing the sample analysis packages and sample collection and transport systems. ...The ExoMars mission is due to be launched in 2009. The Rover will be built to operate autonomously and travel several kilometres over the Martian surface, carrying out in-situ soil sample analyses, and identifying and characterising possible hazards to future human exploration. ...Where possible, the Rover thermal control will be based on existing space-qualified technology used in novel configurations to protect the Rover and its payload from the harsh environment of the Martian surface.
In the UK the Austin Rover Group, were quick to appreciate the potential of the materials to replace cast iron in certain applicaLions and included a ZA-27 enaine mounting bracket in the Maestro family saloon; launched in 1983.
The Range Rover Evoque is a compact luxury SUV, first introduced by Land Rover in 2012. Almost 800,000 units of the first-generation vehicle were sold. ...This approach delivered the most aerodynamic Range Rover at the time of its introduction. The impact of these design changes on the aerodynamic flow field and consequently drag is highlighted.
The paper traces the history of Rover's activities in the automotive gas turbine field. After dealing briefly with the company's successive engine designs, a detailed and expansive survey of its current twin shaft automotive gas turbine, the 2S/140, is given.
The future Mars rover thermal design presents a unique challenge to the thermal engineers: the need arises for a thermal control system able to keep rover elements within their operational and non-operational temperature ranges in the face of extreme environmental conditions, characterized by broad day/night temperature excursions, cold biased conditions and long periods in standby modes induced by dust storms. ...The future Mars rover thermal design presents a unique challenge to the thermal engineers: the need arises for a thermal control system able to keep rover elements within their operational and non-operational temperature ranges in the face of extreme environmental conditions, characterized by broad day/night temperature excursions, cold biased conditions and long periods in standby modes induced by dust storms. ...The demonstrator has been designed, built and tested for exploring its operational envelope, both versus the Rover functioning modes and the Mars environment. Test sequence is described in detail, focusing on the methods to characterize the key parameters of the Heat Switch.
A favored launch vehicle is the extended H-IIA of Japanese manufacture, and a derivative of the Russian Phobos lander would deliver the rovers to the lunar surface.
