Technologies expected to be developed

Telescience and Remote POCC


In the MSL-1 mission, NASDA performs the LIF experiment operation by remote POCC system.POCC(Payload Operations Control Center)is a ground control center where ground operations necessary for on board experiment operations are executed. MSL-1 POCC is located in MSFCCUSA. A new system has been developed to conduct a part for Japanese ground operations from Tsukuba Space Center (TKSC)CJapan,where is convenient for Japanese investigators. This system is named "Remote POCC". The experiment parameters such as temperature, keeping duration, duration of gas evacuation and other control parameters those were decided in Remote POCC are transmitted by dedicated line to MSFC,and are transferred to the LIF on board the Space Shuttle, and experiments are performed. This technique is called Telescience, which enables to operate and observe the experiments on board the Space Shuttle from the ground. By using telescience Investigators can spend more time for preparatory work for the experiments on the ground. Following figure is shown as data transferred image between MSFC and TKSC. Remote POCC in MSL-1 is a first step to the remote experiment operations in the ISS.


Sample Rapid Cooling Experiment Technology

Some of LIF experiments require rapid cooling. Conventional cooling has been performed by applying gaseous helium to the exterior surface of the cartridge. An improved method for MSL-1, which allows helium gas to be applied directly to the sample, provides a rapid cooling capability. While the conventional method is not capable of rapid cooling,the method applied in MSL-1 is efficient, increasing the cooling rate from 0.5degrees/sec to 7degrees/sec.


Electrochemical Experiment Technology

One of the LIF experiment requires supplying electric current to the sample and measuring voltage of the sample, which could not have been performed in the previous experiments. In MSL-1, a method of conducting an electrical experiment was developed. This method is made possible by the Common Electrical Supply Box(C-BOX) and specially designed Electrical Cartridge which interfaces with the sample.
