The Expedition 53 crew trained for a medical emergency in space today after spending the morning on weekly housecleaning tasks. Afterward, two astronauts reviewed procedures and checked their tools ahead of Friday’s spacewalk.
Cosmonaut Alexander Misurkin joined NASA astronauts Mark Vande Hei and Joe Acaba for a routine training session to handle a medical emergency aboard the International Space Station. The trio reviewed medical hardware, chest compression techniques and individual roles and responsibilities.
Afterward, Acaba moved on to spacewalk preparations with Commander Randy Bresnik. The spacewalkers are due to begin a 6.5 hour spacewalk Friday at 8:05 a.m. EDT. NASA TV will cover the spacewalking activities live beginning at 6:30 a.m.
This will be the third spacewalk this month and consists of repackaged tasks that include the replacement of a camera assembly on the newly installed Latching End Effector, the installation of an HD camera on the starboard truss, the replacement of a fuse on Dextre’s payload platform and the removal of thermal insulation on two electrical spare parts housed on stowage platforms.
Howdy NASA,
Most experiments that been done on the board of The International Space Station in respect to growing vegetables in the space, were upon Lettuce, perhaps because Lettuce grows a quickly, therefore it seems like it’s important to use a genetic engineering to change the composition of these vegetables which grows quickly and make it to produce important elements and chemical components that human body needs, such protein and sugar as well as vitamins, to replace storing systems or refrigeration etc. either in on the board of The International Space Station or a spacecrafts of a long space journeys or even during installing human communities on Mars planet, therefore it’s important to urge these sorts as well as researches in respect to finding integral parable artificially living environment, able to be installing on the board of the spacecrafts of long space journeys, to grow these sorts of vegetables after the required genetically modification to grow and to provide a quickly the required important chemical components to the crews members, also a required foods for the astronauts during their long space journeys, in the meantime it’s a very important to urge researches which study to find the possibility of transferring these dangerous cosmic rays to a useful energy, to supply the required energy to run these integral systems to work without depending upon Earth’s supplying of a nuclear batteries during astronauts missions on Mars planet, also that system may protect astronauts of the effects the dangerous cosmic rays during their long space journeys, the cosmic rays have nearly the same particles of radio active materials that used in the nuclear batteries but a little less intensity, Electromagnetic waves in a highly frequencies (Photons ), Beta Ray ( Electrons), Neutrons and Protons either single or as nucleus of atoms, all these rays have a highly engines able to run a nuclear batteries after some modifications.
Good luck.
