Flowers Sent to Mission Control Celebrating SpaceX DM-1 Launch

Flowers Celebrating the SpaceX DM-1 Launch

The last time the Shelton family sent Mission Control Center (MCC) a bouquet of roses was July 9, 2011, the day after the last U.S. space shuttle launched. That was the 110th bouquet from the family and the last U.S. human spaceflight. The Shelton’s continued their tradition Saturday when they sent their 111th bouquet to MCC celebrating the launch of the first SpaceX Crew Dragon.

Ever since the Challenger accident, Mark and Terry Shelton have sent a vase of roses to Mission Control. The two live in the Dallas area and have no job connection to the space program. But they like to show their appreciation by including a rose for each crew member plus a single white one to represent astronauts who died in past accidents.

Correction, June 14, 2018:  This post has been updated to clarify the timing of the first uncrewed test missions, which are planned for later this year.

NASA astronauts Ricky Arnold and Drew Feustel are set to go on their third spacewalk together this year on Thursday at the International Space Station. Their new Expedition 56 crewmates Serena Auñón-Chancellor and Alexander Gerst are training today to support the two spacewalkers.

Arnold and Feustel will begin Thursday’s spacewalk at 8:10 a.m. to install new high definition cameras to support upcoming commercial crew missions from SpaceX and Boeing to the orbital laboratory. The first uncrewed test missions are planned to begin later this year. The cameras will provide improved views of the commercial crew vehicles as they approach and dock to the station. NASA TV will provide complete live coverage of the 211th space station spacewalk starting at 6:30 a.m.

Auñón-Chancellor and Gerst, who just arrived at the station on Friday, will assist the spacewalkers on Thursday. Gerst will help the spacewalkers in and out of their spacesuits. Auñón-Chancellor will operate the Canadarm2 robotic arm. The duo practiced today on a computer the robotics procedures necessary to maneuver a spacewalker to and from the worksite on the starboard side of the station’s truss structure.

Arnold and Feustel had some extra time today to work on science and maintenance activities. Arnold worked with the Microgravity Science Glovebox to troubleshoot a semiconductor crystal growth experiment. Feustel performed some plumbing work in the Tranquility module before relocating a pair of incubator units to support new experiments being delivered on the next SpaceX Dragon cargo mission. Finally, the duo readied the Quest airlock and their spacesuits for Thursday morning’s spacewalk.

The SpaceX Dragon resupply ship is getting ready to return to Earth Friday morning loaded with gear and a variety of science for analysis. Another spacecraft, the Soyuz TMA-20M, will leave Sept. 6 and land in Kazakhstan with three International Space Station crew members.

Dragon delivered numerous science experiments July 20 that the Expedition 48 crew immediately unloaded and began working on. Two of those experiments set to return on Friday include the Heart Cells study and Mouse Epigenetics. That research explored how microgravity affects human heart cells and alters gene expression and DNA in mice.

The station will get an orbital reboost early Wednesday when the docked Progress 63 cargo craft fires its engines for over 12 minutes. The reboost will put the station at the correct altitude for the departure of the Expedition 48 trio next month.

Expedition 48 Commander Jeff Williams and cosmonauts Oleg Skripochka and Alexey Ovchinin will return to Earth in two weeks after 5-1/2 months in space. Williams will be completing his fourth space mission and hold the NASA record for cumulative days in space. Skripochka will be completing his second mission and Ovchinin will be completing his first.

Astronauts Relaxing Before Pair of Spaceships Leave

Three astronauts are relaxing today after a spacewalk on Friday and weekend cleanup work. Meanwhile, a pair of spacecraft will be departing the International Space Station over the next two weeks.

NASA astronauts Jeff Williams and Kate Rubins successfully installed a new international docking adapter Friday morning during a five hour and 58-minute spacewalk. Japanese astronaut Takuya Onishi assisted the duo from inside the station, while all three cleaned up the Quest airlock afterward where they stowed their spacesuits and tools.

Williams is scheduled to return to Earth on Sept. 6 with cosmonauts Oleg Skripochka and Alexey Ovchinin ending Expedition 48. The two cosmonauts began their departure preparations today to get the Soyuz TMA-20M spacecraft ready for undocking and landing in Kazakhstan.

Before Expedition 48 returns home in two weeks the SpaceX Dragon spacecraft will leave the station this Friday at 6:10 a.m. EDT. The crew is loading the space freighter with gear and science for analysis by NASA engineers on the ground. Dragon will splashdown in the Pacific Ocean a few hours after its release Friday and be retrieved by SpaceX personnel.

Two NASA astronauts switched their spacesuits to battery power this morning at 8:04 a.m. EDT aboard the International Space Station to begin a spacewalk planned to last some six and a half hours. Expedition 48 Commander Jeff Williams and Flight Engineer Kate Rubins will install the first of two international docking adapters (IDAs) that will enable future arrivals of Boeing and SpaceX commercial crew spacecraft.

The docking adapter arrived to the space station July 20 on a SpaceX Dragon cargo resupply spacecraft. On Wednesday, ground controllers used the Canadarm2 robotic arm, and its attached “Dextre” Special Dexterous Manipulator, to extract the IDA from the trunk of Dragon and position it just 2 feet away from Pressurized Mating Adapter-2 located on the forward end of the Harmony module.

Once the IDA is moved to a surface to surface contact with the PMA, Williams and Rubins will begin work to hook up tethers in advance of Japan Aerospace Exploration Agency astronaut Takuya Onishi sending commands to close the hooks between the two docking ports. Once the hooks are closed, Williams and Rubins will press ahead to mate power and data connectors for future use of the IDA.

Two spacewalkers, Commander Jeff Williams and Flight Engineer Kate Rubins, will complete the installation work during a spacewalk scheduled to begin Friday at 8:05 a.m. EDT. The NASA astronauts will install cables and outfit the docking port that will enable future Boeing and SpaceX crew vehicles to dock at the International Space Station.

While the spacewalk preparations were under way, a Japanese astronaut and three cosmonauts conducted a variety of space research. Takuya Onishi tended to the mice being observed for the Mouse Epigenetics study. That experiment is researching altered gene expression and DNA changes in mice and their offspring living in space.

Cosmonaut Alexey Ovchinin explored ways of detecting micrometeoroid impacts on the outside of the station. He also joined Oleg Skripochka and studied how galactic and solar radiation genetically affects viruses that infect bacteria. Veteran cosmonaut Anatoly Ivanishin investigated how coulomb crystals and liquids are formed by charged macroparticles and researched how the heart beats in space.

Flight controllers and the Expedition 48 crew are preparing for tonight’s International Docking Adapter extraction work and Friday morning’s installation spacewalk. The orbital residents are also continuing to load the SpaceX Dragon with gear and science for return to Earth.

Controllers on the ground checked the Canadian robotics systems they will use to remove the International Docking Adapter from the rear of the SpaceX Dragon tonight. The new adapter will be extracted with the Canadarm2 then maneuvered to a point about three feet away from its installation point. It will then be installed on the Pressurized Mating Adapter-2 which is attached to the forward end of the Harmony module.

The final and intricate installation work will be done during a 6.5 hour spacewalk scheduled to begin Friday at 8:05 a.m. EDT with astronauts Jeff Williams and Kate Rubins . The new adapter, the first of two, will enable new Commercial Crew vehicles being developed by Boeing and SpaceX to dock at the International Space Station in the future.

In the meantime, the SpaceX Dragon cargo craft is still being loaded with gear ahead of its return to Earth on Aug. 26. Rubins spent the morning packing Dragon with research samples and used hardware for analysis back on Earth.

A pair of astronauts tried on U.S. spacesuits this morning ahead of a spacewalk next week. Afterward, the crew explored heart cells, fluid pressure in the head and the eyes and the composition of meteors.

NASA astronauts Jeff Williams and Kate Rubins are due to work outside the International Space Station on Aug. 19 for 6.5 hours. The duo tried on the spacesuits today they will wear during the spacewalk to complete the installation of the first of two International Docking Adapters to the Harmony module. Commercial Crew vehicles are being developed by Boeing and SpaceX that will dock to the new adapters in the future.

Rubins then moved on to observing heart cells with a specialized microscope. The heart cells are derived from stem cells that were manufactured from human skin cells.

Williams joined cosmonaut Anatoly Ivanishin for ultrasound scans and vision checks. That work was part of the Fluid Shifts study that is exploring how the lack of gravity influences head pressure and eye shape possibly affecting an astronaut’s vision.

Japanese astronaut Takuya Onishi replaced a hard drive on a laptop computer that collects data on the composition of meteors entering Earth’s atmosphere. Cosmonauts Oleg Skripochka and Alexey Ovchinin participated in a study that seeks to improve the ability of a crew member to pilot a spacecraft.
