April 24, 2015 — I believe in one of my first blog posts I mentioned that we were working in an area of high accumulation (snowfall) on the Greenland Ice Sheet. I would like to change that to an area of VERY HIGH accumulation! Actually Southeast Greenland does receive the largest amount of snowfall on the […]
The Russian ISS Progress 57 cargo spacecraft separated from the International Space Station at 2:41 a.m. EDT while the spacecraft were flying 257 miles above northwestern China. After its departure, the spacecraft will move away from the orbiting laboratory to a safe location where it will remain until commanded to reenter Earth’s atmosphere Sunday morning, …
The crew of the International Space Station took a break from research Friday, enjoying some off-duty time as it prepared for the departure of one cargo ship and the arrival of another in short order. NASA Television will provide live coverage of the Progress 57 spacecraft undocking beginning at 2:15 a.m. EDT Saturday, April 25. Undocking …
Pre-Determined Debris Avoidance Maneuver (PDAM): Last night at 8:00 PM CDT the Flight Control Team was notified of a high concern, late notice conjunction. A PDAM was performed today at 12:35 AM CDT using 58P thrusters. Burn duration was 2 minutes, 20 seconds with a Delta-V of 0.3 meters/second. Ocular Health: Padalka and Kornienko, with …
Hello! This is Olivia and I’ll be writing about the hydrology work we are doing this year on the Greenland ice sheet. A few years back some scientists on our team discovered liquid water inside the ice sheet. They partnered with us to study the water in greater depth. We think that the snow melts […]
Ocular Health: Padalka performed his Flight Day (FD) 30 fundoscopy, with assistance from Virts as his CMO and ground remote guiders. The fundoscope is utilized to image the fundus (interior surface of the eye including the retina, optic disc, macula, and fovea). Ocular Health protocol calls for a systematic gathering of physiological data to characterize …
The Expedition 43 lab assistants conducted biomedical science in the International Space Station on Wednesday. Meanwhile, controllers on the ground will remotely maneuver the Canadarm2 outside the station to experiment with the possibility of servicing satellites on orbit for longer missions. The crew participated in a wide variety of life science studies. The Myco experiment, …
Osteocytes and mechano-transduction (Osteo-4): Cristoforetti successfully performed Tray 3 operations, removing the last three bioreactors from Osteo-4, and stowed them in MELFI. The Osteo-4 locker was then powered off. The three trays of Osteo-4 are an automated bone cell culture experiment that studies the effects of microgravity on the function of osteocytes, which are the …
Dust off the lawn chairs and get ready for the peak of the Lyrid meteor shower which will occur on the night of April 22. “The Lyrids are really unpredictable,” Cooke said. “For the 2015 shower, I’m expecting 15 to 20 Lyrid meteors an hour. Peak rates should occur after 10:30 PM on April 22 your local time, …
