The Expedition 63 crew will wait a few more days to gain two new crewmembers after weather scrubbed the initial launch attempt of the SpaceX Crew Dragon. Meanwhile, the orbiting trio aboard the International Space Station continued focusing on lab operations.

Rain and lightning around Kennedy Space Center kept Commercial Crew members Doug Hurley and Bob Behnken on the ground Wednesday. The Florida weather violated launch rules and SpaceX scrubbed the liftoff of the Falcon 9 rocket with the two NASA astronauts atop sitting inside the Crew Dragon vehicle.

NASA has rescheduled the Crew Dragon launch for Saturday at 3:22 p.m. EDT with a backup launch date on Sunday at 3 p.m. If Hurley and Behnken launch Saturday, they would dock Sunday at 10:29 a.m. to the Harmony module’s International Docking Adapter.

Back on orbit, NASA Commander Chris Cassidy was setting up Japanese network communications gear and science hardware during the morning. Afterward, the veteran astronaut spent the rest of Thursday exploring how planetary bodies might affect the density and dynamics of different materials.

The Russian cosmonauts Anatoly Ivanishin and Ivan Vagner started the day transferring cargo to and from the Soyuz crew ship and the two Progress space freighters. The duo then turned its attention to videotaping and photographing their station activities for an Earth audience.

To ensure the agency keeps its commitment for safe operations via a continuous U.S. presence aboard the International Space Station until commercial crew capabilities are routinely available, NASA has completed negotiations with the State Space Corporation Roscosmos to purchase one additional Soyuz seat for a launch this fall.

The agency received no responses from U.S. suppliers to a synopsis issued in the fall of 2019 for crew transportation in 2020. Boeing and SpaceX are in the final stages of development and testing of new human space transportation systems that will launch astronauts from American soil, including NASA’s SpaceX Demo-2 mission scheduled for launch no earlier than May 27.

In case you missed it, NASA Administrator Jim Bridenstine shared why the Demo-2 mission is essential.

The Soyuz spacecraft undocked from the International Space Station at 9:53 p.m. EDT, carrying three people back to Earth. NASA Television will air live coverage beginning at 12 a.m. Friday, April 17, for the deorbit burn at 12:22 a.m. and the spacecraft’s parachute-assisted landing.

NASA astronauts Andrew Morgan and Jessica Meir and Oleg Skripochka are expected to land in their Soyuz MS-15 spacecraft at 1:16 a.m. on the steppe of Kazakhstan southeast of the remote town of Dzhezkazgan (11:16 a.m. Kazakhstan time).

Among the research experiments to which the Expedition 62 crew contributed during their mission was the Droplet Formation Study, which evaluates water droplet formation, water flow and, indirectly, the perceived pressure of current shower head technology as compared to the industry-standard use of jet nozzles. The study examines droplet size and speed and how they affect the feeling of increased pressure for the end user. Another experiment to which the crew contributed was Mochii, a miniature scanning electron microscope used to conduct real-time, on-site imaging and composition measurements of particles. Analysis of small and microscopic particles is a critical need for human space exploration beyond low-Earth orbit when samples cannot be returned to Earth immediately for analysis.

Three Expedition 62 crewmembers are getting ready to head home before U.S., Russian and Japanese spaceship traffic ramps up. Meanwhile, human research activities continue full speed ahead aboard the International Space Station.

NASA astronaut Chris Cassidy will assume command and control of the orbiting lab today at 4:55 p.m. EDT during the Change of Command ceremony live on NASA TV. Commander Oleg Skripochka will turn the keys over to Cassidy before leaving the station on Thursday at 9:53 p.m. EDT when Expedition 63 officially begins.

Cassidy will stay onboard the station until October with Russian cosmonauts Anatoly Ivanishin and Ivan Vagner. This is third station mission for Cassidy and Ivanishin while Vagner is beginning his first.

Skripochka is returning to Earth with NASA Flight Engineers Jessica Meir and Andrew Morgan inside the Soyuz MS-15 crew ship. The trio will parachute to landing in Kazakhstan on Friday at 1:16 a.m. (11:16 a.m. Kazakh time). Morgan will have lived in space for 272 days while Meir and Skripochka will have orbited Earth for 205 days.

The crew collected blood, saliva and urine samples today before stowing them in a science freezer. Scientists on the ground will analyze the samples for markers indicating the effects of microgravity on humans. The orbital residents also contributed to nutrition studies today to understand the crew’s appetite for the station’s food menu and the health impacts of their space diet.

The next spaceship to visit the station is planned for April 24 when Russia’s Progress 75 space freighter launches for a docking to the station’s Zvezda service module. The U.S. Northrop Grumman Cygnus cargo craft will finish its station cargo mission on May 11 when the Canadarm2 robotic arm removes it from the Unity module and releases it back into space. Japan is targeting May 20 for the launch of its HTV-9 Kounotori resupply ship when it will begin a five-day trip to the orbital lab.

The six crewmembers aboard the International Space Station continued advanced space research today promoting health for humans on and off Earth. The crew will split up at the end of the week when the Expedition 62 trio undocks and returns to Earth.

Scientists are looking at how human muscles adapt to microgravity for the Myotones space biology study. NASA astronaut Chris Cassidy began the first of his four sessions for the human research experiment today. He marked muscle points on his skin then used a specialized device to measure his muscles’ biochemical properties. The research could prepare astronauts for longer space missions and help people on Earth with muscle conditions.

His two crewmates, Anatoly Ivanishin and Ivan Vagner, are getting used to life on the orbiting lab while maintaining Russian station hardware. The cosmonauts are deactivating communication systems in the new Soyuz MS-16 crew ship and getting up to speed on their complement of space research.

NASA Flight Engineers Jessica Meir and Andrew Morgan contributed to different experiments today as they complete their final week in space. Meir collected her saliva samples for microbial analysis then documented her thoughts about the station’s food menu. Morgan cleaned and closed out life science hardware that housed live mice that returned to Earth on the last SpaceX Dragon cargo mission.

The two astronauts are also getting ready to end their mission with Commander Oleg Skripochka and return to Earth on Friday. The trio is packing the Soyuz MS-15 crew ship with cargo and personal items. They will undock Thursday at 9:53 p.m. EDT and parachute to landing in Kazakhstan less than three-and-half hours later.

Three new crewmembers are getting used to life aboard the International Space Station. Meanwhile, the Expedition 62 trio is getting ready for its return Earth on Friday.

Three NASA astronauts and three Roscosmos cosmonauts have been working together on the orbiting lab since April 9 when the Expedition 63 crew docked to the station’s Poisk module. U.S. astronaut Chris Cassidy is leading Russian cosmonauts Anatoly Ivanishin and Ivan Vagner during their 195-day mission.

They will be familiarizing themselves with station systems and getting up to speed with science work over the next several days. Cassidy put on virtual reality goggles this morning for an experiment monitoring how he visually interprets motion, orientation and distance in microgravity. Ivanishin and Vagner were researching space biology and technology studies today, as they get used to their new orbiting home 260 miles above Earth.

Expedition 62 Flight Engineers Jessica Meir and Andrew Morgan with Commander Oleg Skripochka will complete their station mission on Friday when they return to Earth. They are packing their Soyuz MS-15 crew ship and reviewing landing procedures this week. They are also familiarizing themselves with the conditions they will experience upon reentering Earth’s atmosphere and feeling gravity for the first time in months.

Skripochka will hand over station control to Cassidy on Wednesday at 5:55 p.m. EDT during the Change of Command Ceremony live on NASA TV. The Expedition 62 crew will undock in the Soyuz vehicle on Thursday at 9:53 p.m. They will shoot through the atmosphere in the Soyuz descent module and parachute to a landing in Kazakhstan at 1:17 a.m. (11:17 a.m. Kazakh time).
