Trio Surpasses 100 Days as Dragon Unloads Earth Science

Three Expedition 50 crew members recently surpassed 100 days in space and will come home in June. Also, SpaceX Dragon external experiments are being unloaded for installation on the International Space Station.

NASA astronaut Peggy Whitson has been living in space with her Expedition 50 crewmates for over 100 days now. She and Thomas Pesquet from the European Space Agency and Oleg Novitskiy from Roscosmos will return to Earth June 2 after 197 days in space. The trio launched Nov. 17 beginning a two-day trip to the station.

Whitson has reached out to her supporters on the ground and mentioned them with her “NASA Village” campaign from space. She launched to the station with posters signed by hundreds of support personnel and recently showed them off on orbit.

A pair of Earth observation experiments delivered last week on the SpaceX Dragon have been robotically removed from the resupply ship. Both experiments will be installed on specialized pallets on the outside of the orbital laboratory and activated for years of research.

The first experiment, SAGE-III, will observe how tiny particles interact with Earth’s sunscreen, or ozone, possibly affecting the climate. The second, Lightning Image Sensor, will monitor lightning around the globe to improve weather forecasting, enhance climate models and increase aviation safety.

Station Lifts Orbit, Crew Explores Diet and Stem Cells

(From left) Crewmates Thomas Pesquet, Oleg Novitskiy and Peggy Whitson just recently celebrated 100 days in space. The trio is scheduled to return to Earth June 2.

The International Space Station fired its engines Wednesday night slightly raising its orbit to accommodate a crew exchange in April. In the meantime, the six-person Expedition 50 crew continued learning how living in space affects the human body.

The station’s third module, the Zvezda service module which launched in 2000, fired its main engines for 43 seconds overnight. The orbital reboost places the station at the correct altitude for the departure of three Expedition 50 crew members April 10. Just ten days later, two new space residents will arrive completing the Expedition 51 crew.

Scientists are exploring the best nutrition requirements to keep astronauts healthy and productive during long-term space missions. Astronaut Thomas Pesquet is contributing to that research today beginning a prescribed diet for the next 11 days. During that period he will collect urine samples and measure his breathing for the Energy study. Results will help researchers plan meals to ensure successful missions farther out into space.

Flight Engineer Peggy Whitson, who will become station commander April 9, peered at stem cells through a specialized microscope on today. She is helping scientists understand how microgravity increases stem cell replication possibly improving disease treatments on Earth.

The International Space Station will boost its orbit Wednesday night to get ready for a crew swap next month. Three Expedition 50 crew members will complete their mission and a new two-person crew will launch to the station in April.

Commander Shane Kimbrough and his crewmates Sergey Ryzhikov and Andrey Borisenko will end their mission April 10 after 173 days in space. The trio will undock from the Poisk mini-research module in their Soyuz MS-02 spacecraft officially ending the Expedition 50 mission.

The reboost also readies the station for the arrival of two new crew members who will arrive April 20. Veteran cosmonaut Fyodor Yurchikhin and NASA astronaut Jack Fischer, a first-time space flyer, will take a short four-orbit ride aboard the Soyuz MS-04 spacecraft and dock to Poisk. The new Expedition 51 trio is scheduled to stay in space for 136 days.

NASA astronaut Peggy Whitson will become Expedition 51 commander after Kimbrough and his crew undock. She is staying behind with fellow crewmates Thomas Pesquet from France and Oleg Novitskiy from Russia. They will stay in space until June 2 ending their mission after 195 days when they return home in their Soyuz MS-03 spacecraft.

Engineers on the ground switched from one pump to another in the thermal cooling system for one of the particle detectors on the Alpha Magnetic Spectrometer (AMS), an experiment to study cosmic ray particle physics from the outside of the International Space Station. The silicon tracker is one of several detectors that collect data on cosmic particles and is equipped with four redundant pumps used to circulate carbon dioxide to maintain the required temperature in the changing thermal environment outside the station. A pump stopped functioning on Tuesday, Feb. 28, 2017, and was the second to stop after a different pump experienced a similar issue in March, 2014. Only one pump is required to operate at a given time, and long-term planning is underway to potentially bypass the pumps and associated equipment with an upgraded system put in place during a series of spacewalks. AMS launched in 2011, and results have already contributed to science showing potential indirect evidence of dark matter and other new cosmic ray particle physics discoveries.

Crew Checks Spacesuits and Explores New Life Science

Astronauts Thomas Pesquet and Peggy Whitson set up the Microgravity Science Glovebox inside the Destiny lab module.

Astronaut Thomas Pesquet of the European Space Agency cleaned U.S. spacesuit cooling loops and collected water samples for a periodic maintenance check today. Afterward, he began charging spacewalking gear including helmet lights and tool batteries.

Commander Shane Kimbrough and NASA astronaut Peggy Whitson worked on life support maintenance today. They removed and disassembled valves and ducts to access old carbon dioxide filters that needed replacing inside the Destiny lab module. The duo will be back at work Wednesday installing newer generation filters.

One of the main objectives of the International Space Station is to provide an orbital laboratory to research how living in space long-term affects humans. New and ongoing experiments conducted today may provide benefits for humans on and off Earth.

Kimbrough checked on rodents being observed for a tissue regeneration study. Whitson continued researching stem cells with a new microscope delivered last week aboard the SpaceX Dragon. Cosmonaut Andrey Borisenko studied how viruses behave in space while his fellow cosmonauts, Sergey Ryzhikov and Oleg Novitskiy, explored non-invasive ways to monitor a crew member’s health and methods to keep their skills sharp on and off Earth.

Brand New Dragon Experiments Activated on Station

The Expedition 50 crew began activating new science experiments delivered last week aboard the SpaceX Dragon. The various life science studies will study bones and muscles, stem cells, botany and protein crystals.

Rodents delivered aboard Dragon were placed in their habitats over the weekend for the Rodent Research-4 study. That experiment is observing how bone and tissue regenerate in microgravity.

Stem cells were also unloaded from Dragon and stowed in a science freezer. The crew will research the replication of stem cells which may benefit clinical trials on Earth for new disease treatments. Astronaut Peggy Whitson used a specialized microscope to view the stem cells as the experiment got under way over the weekend.

The crew is also exploring how plants grow in space in order to provide food and oxygen for future long-duration missions. Plant samples were removed from a science freezer and placed in the Veggie facility for growth and observation. The spaceflight environment can change a plant’s genetic expression and growth pattern.

High-quality crystals are being grown on the International Space Station that otherwise couldn’t be grown on Earth due to gravity. The crystal samples are being studied for the Light Microscopy Module Biophysics-1 experiment to help researchers design new disease-fighting drugs.

Dragon Arrival at Station on NASA TV Now

The International Space Station and SpaceX Dragon flight control teams are proceeding toward rendezvous and grapple of an unpiloted Dragon cargo craft on Thursday, Feb. 23. NASA Television coverage has begun. Watch live at http://www.nasa.gov/live.

Grapple is expected around 6 a.m. Installation of the Dragon to the Earth-facing port of the Harmony module will begin a couple hours later. NASA TV coverage of installation is set to begin at 8 a.m.

The Dragon launched atop a Falcon 9 rocket from Cape Canaveral Air Force Station in Florida on Sunday, Feb. 19. During the initial scheduled rendezvous on Wednesday morning, the spacecraft’s computers received an incorrect navigational update, which triggered an automatic wave off.

SpaceX CRS-10 is scheduled to deliver about 5,500 pounds of supplies and payloads to the station, including critical materials to directly support dozens of the more than 250 science and research investigations that will occur during Expeditions 50 and 51.

Crew Prepares for U.S. and Russian Space Deliveries

NASA and SpaceX flight controllers in Houston and Hawthorne, California are reworking plans for the arrival Thursday of the SpaceX Dragon cargo craft after its rendezvous to the International Space Station was aborted early Wednesday morning. The Dragon’s computers received an incorrect navigational update, triggering an automatic wave off.

Dragon was sent on a “racetrack” trajectory in front of, above and behind the station for a second rendezvous attempt Thursday. Dragon is in excellent shape and neither the crew nor the station were in any danger. NASA TV will cover its second rendezvous attempt Thursday beginning at 4 a.m. EST.

Expedition 50 commander Shane Kimbrough and Thomas Pesquet will be back in the cupola Thursday waiting to capture Dragon at around 6 a.m. Flight Engineer Peggy Whitson will be assisting the duo monitoring Dragon’s arrival and its systems.

A few hours before Dragon aborted its rendezvous, Russia launched its Progress 66 (66P) resupply ship from Kazakhstan on a two-day trip to the station’s Pirs docking compartment. The 66P is carrying nearly three tons of food, fuel and supplies to the six-member Expedition 50 crew. It will arrive Friday for an automated docking at 3:34 a.m. and stay at the station until June. NASA TV will also cover its arrival starting at 2:45 a.m.
