Two astronauts are preparing a pair of U.S. spacesuits to get ready for next weeks spacewalk to continue the maintenance of the International Space Station. In the midst of those preparations, the six-member Expedition 46 crew is proceeding with ongoing space science to improve life on Earth and benefit future astronauts.

Tim Kopra from NASA and Tim Peake from the European Space Agency will be the spacewalkers on Jan. 15. They will work outside for about six-hours and 30-minutes to replace a failed voltage regulator, rig cables for future International Docking Adapters and perform other maintenance tasks.

The station residents also worked throughout the day on a variety of experiments exploring human research, physics and other advanced subjects.

Commander Scott Kelly joined cosmonaut Mikhail Kornienko for the Fluid Shifts study. That experiment observes how microgravity increases brain pressure which may push back on a crew members eyes, resulting in changes to their vision. Peake and Kopra also participated in life science experiments exploring heart function during long-term space missions and the efficacy of medications in space.

Astronauts Tim Peake and Tim Kopra are getting ready for a spacewalk next week to replace a failed voltage regulator. The duo are scheduled to work outside for 6.5 hours on Jan. 15 for the replacement work and other tasks.

In preparation, Kopra worked on the U.S. spacesuits today that he and Peake will wear next week. Peake, a British astronaut with the European Space Agency, began collecting and configuring their spacewalk tools.

The Expedition 46 crew also continued more advanced space science research onboard the International Space Station. Commander Scott Kelly joined his fellow One-Year crew member Mikhail Kornienko for the Fluid Shifts study. That experiment explores how microgravity increases brain pressure which pushes back on a crew members eyes,resulting in changes to their vision.

Cosmonaut Sergey Volkov studied radiation exposure, how international crews relate during missions and worked on maintenance tasks. His fellow cosmonaut and flight engineer Yuri Malenchenko looked at magnetic fields and coulomb crystals and transferred cargo from the newest Progress 62 cargo craft.

The Expedition 46 crew begins its first full week of the New Year planning for a spacewalk scheduled for Jan. 15. The orbiting residents are also busy with numerous science experiments benefitting life on Earth and future astronauts.

A pair of spacewalkers will replace a failed voltage regulator to return power to one of eight power channels next Friday. Two crew members will exit the Quest airlock and work outside for 6.5 hours for the replacement work. They will also rig cables for the future installation of docking adapters that will enable commercial crew vehicles to dock at the International Space Station. Final spacewalking roles will be confirmed following spacesuit hardware checkouts taking place today.

NASA astronauts Tim Kopra and Commander Scott Kelly collected and stowed blood and urine samples this morning for the Fluid Shifts study. That experiment observes the headward fluid shift caused by microgravity that increases brain pressure and pushes back on the eye. British astronaut Tim Peake also explored particles suspended in fluids, or colloids, which could benefit the design of advanced materials on Earth.

Traveling about 253 miles over western Mongolia, the unpiloted ISS Progress 62 Russian cargo ship docked automatically with the Pirs docking compartment of the International Space Station at 5:27 a.m. EST today. Progress is delivering 2.8 tons of food, fuel, and supplies to the crew aboard the station.

The spacecraft launched Monday from the Baikonur Cosmodrome in Kazakhstan. Following a by-the-book rendezvous and docking with the Progress upgraded Kurs automated system, hooks formed a hard mate between the spacecraft and the Pirs docking compartment. Once the crew completes leak checks, the hatches will open, allowing the crew to unload the cargo.

The Progress spacecraft will remain docked until early July 2016.

A pair of spacewalkers are cleaning up and reporting back to ground controllers after a short spacewalk Monday morning. A Christmas delivery is also due at the International Space Station Wednesday at 5:31 a.m. EST/10:31 a.m. UTC.

Commander Scott Kelly and Flight Engineer Tim Kopra quickly prepared over the weekend for the spacewalk to release a stalled robotic transporter. As the pair suited up in the Quest airlock Monday, a Progress 62 (62P) cargo spaceship launched on a two-day trip to deliver 2.8 tons of food, fuel, and supplies for the Expedition 46 crew.

The stalled robotic transporter needed to be moved then latched to its worksite ahead of the Progress arrival triggering Mondays spacewalk. The Progress is a modified design and Russian mission controllers are testing its upgraded software and telemetry systems during its flight to the Pirs docking compartment.

Cosmonauts Yuri Malenchenko and Sergey Volkov are preparing for the Progress arrival by testing the TORU tele-robotic rendezvous system. The TORU system would be used in the unlikely event it would be necessary to manually guide the vehicle to a docking.

The crew also had time set aside for advanced space science today. The orbiting lab residents explored plant growth and life science as humans learn to live longer and farther in space.

NASA astronauts Scott Kelly and Tim Kopra ended their spacewalk at 11:01 a.m. EST with the repressurization of the U.S. Quest airlock after accomplishing all objectives. They released brake handles on crew equipment carts on either side of the space stations mobile transporter rail car so it could be latched in place ahead of Wednesdays docking of a Russian cargo resupply spacecraft. The ISS Progress 62 resupply mission launched at 3:44 a.m. EST this morning (2:44 p.m. Baikonur time) from the Baikonur Cosmodrome in Kazakhstan.

After quickly completing their primary objective for the spacewalk, Kelly and Kopra tackled several get-ahead tasks. Kelly routed a second pair of cables in preparation for International Docking Adapter installment work to support U.S. commercial crew vehicles, continuing work he began during a November spacewalk. Kopra routed an Ethernet cable that ultimately will connect to a Russian laboratory module. They also retrieved tools that had been in a toolbox on the outside of the station, so they can be used for future work.

The three-hour and 16-minute spacewalk was the third for Kelly, who is nine months into a yearlong mission and the second for Kopra, who arrived to the station Dec. 15. It was the 191st in support of assembly and maintenance of the orbiting laboratory. Crew members have now spent a total of 1,195 hours and 20 minutes working outside the orbital laboratory.

Spacewalkers Scott Kelly and Tim Kopra.

NASA astronauts Scott Kelly and Tim Kopra switched their spacesuits to battery power at 7:45 a.m. EST, signifying the start of todays spacewalk, planned for about three hours.

Kelly is wearing a spacesuit with red stripes and is designated EV1. His helmet camera displays the number 18. Kopra is wearing a spacesuit with no stripes and is designated EV2. His helmet camera displays the number 17.

The astronauts are embarking on the 191st spacewalk in support of space station assembly and maintenance to move the space stations mobile transporter rail car a few inches from its stalled position so it can be latched in place ahead of Wednesdays docking of a Russian cargo resupply spacecraft.

If the primary task of moving the transporter to its worksite is completed quickly, Kelly and Kopra may press on to a few get-ahead tasks that include the routing of cables in advance of International Docking Adapter installment work to support U.S. commercial crew vehicles, and opening a door housing power distribution system relay boxes just above the worksite to facilitate the future robotic replacement of modular components.

The International Space Station Mission Management Team met Sunday and gave its approval to proceed with a spacewalk Monday out of the Quest airlock by Expedition 46 Commander Scott Kelly and Flight Engineer Tim Kopra of NASA to assist in moving the Mobile Transporter rail car a few inches to a worksite on the stations truss where it can be latched in place and electrically mated to the complex. The green light for the unplanned spacewalk to take place Monday came three days after the Mobile Transporter stalled just four inches away from its embarkation point at worksite 4 near the center of the stations truss as it began to move to another worksite to support robotic payload operations with its attached Canadarm2 robotic arm and the Special Purpose Dexterous Manipulator (Dextre).

Station managers ordered the spacewalk to latch down the transporter as a cautionary measure in advance of the scheduled docking of the new unpiloted ISS Progress 62 cargo ship on Wednesday that will link up to the Pirs Docking Compartment. The Progress is on track for launch from the Site 31 launch pad at the Baikonur Cosmodrome in Kazakhstan Monday at 2:44 a.m. Central time (2:44 p.m. Baikonur time).

The planned 3 to 3 hour spacewalk is scheduled to begin Monday at 7:10 a.m. Central time. The start time for the spacewalk is variable since Kopra will be conducting a fit check of his U.S. spacesuit in parallel with other spacewalk preparations. NASA TV coverage will begin at 5:30 a.m. Central time.

Kelly, who will be making his third spacewalk, will be extravehicular crew member 1 (EV 1) wearing the U.S. spacesuit bearing the red stripes. Kopra, who arrived on the station on Dec. 15, will be making the second spacewalk of his career as extravehicular crew member 2 (EV 2) wearing the suit with no stripes. It will be the 191st spacewalk in support of station assembly and maintenance and the seventh spacewalk of the year by station crew members.

Kelly and Kopra will float out of the Quest airlock to the area where the Mobile Transporter has stalled to check out the position of its brake handles and other mechanisms to make sure the rail car can be commanded to move back to worksite 4 by robotic flight controllers at Mission Control, Houston. It is suspected that a brake handle on an equipment cart attached to the starboard side of the transporter may have inadvertently engaged, which if correct, should easily be released to allow for the transporter to be moved into place for its latching.

If the primary task of moving the transporter to its worksite is completed quickly, Kelly and Kopra may press on to a few get-ahead tasks that include the routing of cables in advance of International Docking Adapter installment work to support U.S. commercial crew vehicles, and opening a door housing power distribution system relay boxes just above the worksite to facilitate the future robotic replacement of modular components.

Let's ignore the technologies that might be impossible (e.g. warp drive, dilithium crystals, and transporters). Let's ignore the technologies that we have no idea how to reproduce in a similar way (artificial gravity). Let's just focus on trying to build a space-worthy scale replica of the USS Enterprise that uses existing structural and propulsion capabilities.

An artificial structure in space, where people live and work. Unlike the Cool Starship, the Space Station is usually fixed in orbit around a planet or at a particular point in space. It also allows for the construction of a standing studio set and avoids expensive location shoots. Real-world space stations have existed since 1971 (Salyut 1) and 4 of themthe International Space Station, the Chinese Tiangong-1, and Genesis I & II (both unmanned)are currently in orbit. These are all much smaller than what one is used to in sci-fi shows. The list for the interested can be seen below. Space stations in fiction have a tendency to be very large, sometimes housing an entire city. Many have adopted a wheel design for a centrifuge-based system of gravity (unless Artificial Gravity is employed), but this is not obligatory. If sufficiently large to support a sizable permanent population, a space-station may be referred to as an "orbital habitat" or "space colony". Don't drop it! The problem of gas exchange and food production is often solved by incorporating a closed ecosystem and green plants onboard, sometimes in dirt, sometimes hydroponics, sometimes algae aquaculture.

Excerpt from:
Space Station - TV Tropes

In the exploration of the western frontier of the Unites States, pioneers had forts or staging points where they departed to venture into the unexplored territories. Similarly, in the early 20th century, pioneering space scientists, such as Hermann Oberth, Konstantin Tsiolkovsky, Hermann Noordung and Wehrner von Braun, dreamed of vast space stations orbiting the Earth. Like forts in the western frontier, these scientists envisioned space stations as staging points for the exploration of outer space.

Wehrner von Braun, the architect of the American space program, integrated space stations into his long-term vision of U.S. space exploration. To accompany von Braun's numerous space articles in popular magazines, artists drew concepts of space stations. These articles and drawings helped fuel public imagination and interest in space exploration, which was essential to establishing the U.S. space program (for more, see How the Space Race Worked).

In these space station concepts, people lived and worked in outer space. Most of the stations were wheel-like structures that rotated to provide artificial gravity. Like any port, ships traveled to and from the station. The ships carried cargo, passengers, and supplies from Earth. The departing flights went to Earth, the Moon, Mars and beyond. As you know, this general concept is no longer merely a vision of scientists, artists and science fiction authors. But what steps have been taken to build such orbiting structures? While mankind has not yet realized the full visions of von Braun and others, there have been significant strides in building space stations.

The United States and Russia have had orbiting space stations since 1971. The first space stations were the Russian Salyut program, the U.S. Skylab program and the Russian Mir program. And since 1998, the United States, Russia, the European Space Agency, Canada, Japan and other countries have been building and operating the International Space Station (ISS) in Earth orbit. With the ISS, humans have been living and working in outer space for more than 10 years.

In this article, we'll examine the early space station programs, the uses of space stations, and the future role of space stations in the exploration of outer space. But first, let's consider more fully why many people think we should be building space stations.
