More information has emerged on the European Space Agency (ESA) Rosetta mission which is currently orbiting the comet in our solar system. Two main information has actually emerged: specific data calculations about the Rosetta mission, and your ability to print your own 3D Rosetta files with your own printers. A 3D printer and the appropriate software could be used to print photos of the comet, and the resulting image files would be in .wrl or .obj formats.
However, the Rosetta probe has high-resolution Osiris cameras mounted on it, and it is expected that the high-resolution pictures that the probe would take would produce quality images to be printed through 3D by interested persons.
On coming November 12th, the Rosetta will land a robot on mars by piggybacking its Philae lander in an operation that will last seven hours. The only consideration now is the likelihood of success at landing the machine at the designated lobes on mars, and the fear is due to the rough terrain of the destination point under review.
The measurement of the head or duck for landing which had been kept secret before this time has been found to be 2.5km by 2.5km by 2.0km, and the “body” is described as being 4.1km by 3.2km by 1.3km. Measured against the initially released mass of 10 billion tonnes and a density of 400kg per cubic metre published recently, this makes for an object that has a volume of 25 cubic km. Its rotation rate is also now known to at least six significant figures – at 12.4043 hours. Other specification details available now available to the public are as follows:
- Spin axis: Right ascension – 69 degrees; Declination – 64 degrees
- Water vapour production rate: 300ml/sec (Jun 2014); 1-5 l/sec (Jul-Aug 2014)
- Surface temperature: minus 68C to minus 43C (Jul-Aug 2014)
- Subsurface temperature minus 243C to minus 113C (Aug 2014)
- Gases detected: Water, carbon monoxide, carbon dioxide, ammonia, methane, methanol
- Dust grains sizes detected: A few tens of microns to a few hundreds of microns
