New Mars Rover Digitally Designed and Tested

31.07.2012
NASA scientists used software from Siemens to help create the new Mars rover Curiosity, which is currently on its way to Mars. The 900-kilogram rover is the largest Mars vehicle to date.

It will reach the red planet on August 6, 2012, and begin to conduct various experiments to obtain new information, which it will transmit back to earth. Development software from Siemens helped to ensure that all of the components fit together, work properly, and withstand the mission's harsh conditions.



Scientists at NASA's Jet Propulsion Laboratory used Siemens PLM (product lifecycle management) software during the vehicle's entire development process in order to digitally design and simulate the rover and virtually assemble it without having to build a prototype.

Mars rovers have to fulfill particularly tough requirements during launch, while traveling through space, when entering Mars' atmosphere, and while landing on the planet's surface. As a result, Curiosity has to be able to withstand extreme differences in temperature, high acceleration rates, and intense vibrations and radiation.

Thus, the design and production of such rovers is an extremely complex task. Moreover, there's no second chance during a space mission, as nothing can be corrected or repaired after the launch.

To develop the vehicle, the NASA scientists therefore used Siemens' PLM software with the construction software NX and Teamcenter for data management. Teamcenter enhances the cooperation between different design teams by always providing them with the latest data. The NX software consists of CAD, CAE, and CAM applications for computer-aided design, development, and production.

Among other things, NX was used to create a temperature model of the rover. To do this, the researchers used hundreds of temperature sensors to test the rover in a special chamber in which a carbon dioxide atmosphere, a super-cold floor, and a sun-like radiation source imitated the conditions on the Mars surface. NX used the collected data and results to calculate a temperature model that can virtually simulate conditions that cannot be duplicated on earth. In addition to helping the researchers design and test the system, the 3D model is currently being used during the flight.

Siemens' PLM software is widely used in the aerospace and car industry. In combination with Siemens' automation technology, the software reduces the time to market by up to 50 percent and helps save resources and energy.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
