Viking Lander 2 Mars seismology data released

Mars seismic data obtained by Viking Lander 2 mission in 1970's are released from DARTS. The original data were processed by UTIG and MIT independently. Therefore, there have been two different datasets in the world from the same measurement. The UTIG processed data were sent to ISAS together with the Apollo seismic data. The MIT processed data have been archived at NSSDC, which, unfortunatelly, do not seem to be widely used. At DARTS, we provide both datasets with technical description. To validate them, we have compared the two versions of the datasets. As a result of the comparison, they are found to be essentially identical, although formats are different. For instance, the famous figure published in the old report "Seismology on Mars" in 1977 (right, top) can be newly re-constructed using the MIT version of the data: DD030692_F3/8260, 8270, 8280, 8290, 8300 (right, bottom).

ISS Japanese Experimental Module (JEM)/Kibo experimental data released

Experimental data concerning fluid physics and crystal growth obtained in the Pressurized Module (PM) of Kibo aboard the International Space Station are publicly released. The released dataset contain video images and digital data such as temperature, voltage, etc. under various experimental conditions. These data are widely opened to scientists in worldwide, and are expected to produce new scientific knowledge. The image in the right-hand side, which looks like a tree-leaf, is obtained in the ice-crystal growth experiment (dendrite crystal growth). (Apr. 2015)
