The Expedition 71 crew members continue packing the SpaceX Dragon spacecraft and preparing for its return to Earth this weekend. Meanwhile, the cosmonauts cleaned up following a successful spacewalk at the International Space Station on Thursday.
Mission managers are monitoring weather conditions off the coast of Florida and are now targeting no earlier than 12:05 p.m. EDT on Sunday for the undocking of the SpaceX Dragon cargo spacecraft. The NASA astronauts have spent the week packing Dragon with completed science experiments and research samples that will be analyzed in laboratories on Earth. On Friday, Flight Engineers Tracy C. Dyson and Matthew Dominick securely transferred into Dragon mice treated with a genetic therapy that may prevent space-caused vision issues. Scientists on the ground will evaluate the space rodents and compare them to a control group on the ground.
NASA Flight Engineer Jeanette Epps swabbed placards the crew had been touching at regular intervals and collected microbe samples for the Antimicrobial Coatings experiment. The samples were placed in transfer tubes for stowage on Dragon and analysis on Earth. Special coatings on surfaces are being tested for their ability to inhibit microbial growth and prevent bacteria contamination in space and Earth systems protecting astronauts and Earthlings.
NASA Flight Engineer Mike Barratt spent Friday on a pair of biotechnology experiments to boost health on and off the Earth. He started his day preparing bacteria samples for DNA sequencing. Researchers seek to identify antibiotic resistant organisms, how microgravity affects their evolution, and protect space crews. Barratt then spent the afternoon processing cardiac tissue samples printed in the BioFabrication Facility, a 3D bioprinter. Results may allow crews to print meals and medicines and doctors on Earth to manufacture organs for patient surgeries.
The orbital lab’s three cosmonauts slept in on Friday following a four-hour and 36-minute spacewalk to install hardware and science experiments on the station’s Roscosmos segment. This was the second spacewalk that Commander Oleg Kononenko and Flight Engineer Nikolai Chub had conducted together. The duo woke up late on Friday and began cleaning and removing components from their Orlan spacesuits. Flight Engineer Alexander Grebenkin, who assisted the spacewalkers on Thursday, retrieved radiation sensors from the spacesuits and documented the recorded data.
The space station is orbiting higher today after the Progress 87 resupply ship, docked to the Zvezda service module’s aft port, fired its engines for nearly seven minutes on Thursday night. The orbital reboost puts the orbital outpost at the correct altitude for the arrival of the next cargo craft from Roscosmos, the Progress 88, due in late May.
Launch preparations are moving full steam ahead to send two NASA astronauts aboard Boeing’s Starliner spacecraft for the first time to the International Space Station. NASA, Boeing, and ULA (United Launch Alliance) recently completed a start-to-finish mission dress rehearsal on April 26, for the upcoming Crew Flight Test.
The mission will launch NASA astronauts Butch Wilmore, commander, and Suni Williams, pilot, on Boeing’s Starliner on a ULA Atlas V rocket from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. Liftoff is scheduled for 10:34 p.m. EDT, Monday, May 6.
During the dress rehearsal, Wilmore and Williams completed a series of launch day milestones including suiting up, working in a flight deck simulator, and operating the same software that will be used during the launch. After loading out Building at NASA’s Kennedy Space Center in Florida and convoyed to the Vertical Integration Facility at nearby Cape Canaveral to run through countdown procedures with the integrated Atlas V rocket and Starliner stack.
The crew will spend about a week at the orbiting laboratory before the crew capsule returns to Earth, making a parachute and airbag-assisted landing in the southwestern United States.
After successful completion of the mission, NASA will begin the final process of certifying Starliner and its systems for crew rotation missions to the space station. The Starliner capsule, with a diameter of 15 feet (4.56m) and the capability to steer automatically or manually, will carry four astronauts, or a mix of crew and cargo, for NASA missions to low Earth orbit.
NASA concluded its Flight Test Readiness Review for the agency’s Boeing Crew Flight Test and teams are proceeding toward a planned launch at 10:34 p.m. EDT on Monday, May 6, to the International Space Station.
