Plant Gravity Sensing 2 (PGS2) Run 1: Following up on Lindgren’s treatment yesterday of the growing plants with a chemical reagent that induces a bioluminescence response, today Yui removed the reagent with an absorbent and placed them in a Photon Counting Unit (PCU). Photon measurements will be taken over the next 24 hours. Lindgren noted …
The Expedition 45 residents worked on biomedical experiments Thursday observing how humans adapt to long-term missions in space. A pair of NASA astronauts is also getting ready for two upcoming spacewalks outside the International Space Station. Commander Scott Kelly joined Flight Engineers Kjell Lindgren, Kimiya Yui and Oleg Kononenko for eye exams throughout the day …
In two weeks, NASA astronauts Scott Kelly and Kjell Lindgren will step outside the U.S. Quest airlock for the first of two maintenance spacewalks. The International Space Station is also being readied to host the next Orbital ATK Cygnus cargo mission set for early December. Japanese astronaut Kimiya Yui has been servicing the two spacesuits …
Plant Gravity Sensing 2 (PGS2): Today Lindgren retrieved culture dishes from a Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) and treated the plants growing in them with a chemical reagent that induces a bioluminescence response that is dependent on the concentration of calcium ions in the plants. The Plant calcium concentrations have been …
Body Measures: Lindgren, with Kelly as the operator, completed his Flight Day 80 Body Measures data collection. Lindgren set up the cameras and video, donned the body marker instrumentation, and then collected the calibration and body pose photographs and physical body measurements. With Kelly’s assistance he collected the Neutral Body Posture video. NASA is collecting …
Hello! It's Kelsi Singer again from the New Horizons science team to talk about one of my favorite planetary geologic features –impact craters. They may just look like holes in the ground, but amazingly, craters can give us all sorts of useful clues to a planet's history. There are many ways scientists investigate a planet …
The six-member Expedition 45 crew focused on human research and physics Tuesday as NASA prepares for deep space missions and learns how to live in space for longer periods. Two astronauts are also getting ready for a pair of maintenance spacewalks beginning at the end of the month. Commander Scott Kelly and Flight Engineer Kjell …
Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) Vertigo: Kelly and Yui set up and performed a SPHERES Vertigo run today. This investigation uses the SPHERES free-flying satellites to demonstrate and test enhanced technologies and techniques related to visual inspection and navigation. This effort incorporates hardware and software that enables multiple SPHERES to construct 3 …
NanoRack Cubesat Deployer (NRCSD) #6 Operations: Overnight, three unsuccessful attempts were made to retract the secondary latch associated with deployer # 6, which would have allowed the deployment of the remaining two cubesats for this operation. The next troubleshooting attempt to launch the cubesats will involve cycling the latches during a Japanese Experiment Module Remote …
The Draconids are an “occasional” shower – they are either in outburst, with a fair number of meteors, or are so few the casual observer would not notice them. Rates this year are expected to be about 10 per hour on the night of October 8 into the early morning of the 9th, most of …
