59 Progress (59P) Status: 59P launched from Baikonur Cosmodrome in Kazakhstan at 2:09 AM CDT and achieved orbital insertion. Shortly after the third stage separation, the ground experienced partial loss of communication with the vehicle. Mission Control Center (MCC)-Moscow attempts to re-gain communication with the vehicle over subsequent ground passes were unsuccessful. The next troubleshooting …

On Tuesday, Apr. 28 at 2:45 a.m. EDT, NASA Television will provide live coverage of the launch of a Russian Progress spacecraft carrying more than three tons of food, fuel, and supplies for the Expedition 43 crew aboard the International Space Station. Launch of ISS Progress 59 from the Baikonur Cosmodrome in Kazakhstan is planned …

59 Progress (59P) Launch/Dock: 59P is scheduled to launch tomorrow from Baikonur Cosmodrome in Kazakhstan at 2:09 AM CDT. Docking to the ISS Docking Compartment (DC)-1 is scheduled to occur tomorrow at 8:07 AM CDT. Rodent Research-2 Center for the Advancement of Science in Space (RR-2 CASIS): Virts and Kelly configured the Bone Densitometer and …

The Expedition 43 crew kicked off a new week by focusing on a number of biological experiments. The crew participated in the Sprint study which evaluates the use of high intensity, low volume exercise training to minimize loss of muscle, bone, and cardiovascular function in crew members during long-duration missions. Crew members also took part …

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 …

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 …
