City lights from space

Posted on by

An urban sprawl engulfs San Francisco Bay in a sea of lights. The three bridges Oakland Bay Bridge, San Mateo Bridge and Dumbarton Bridge glow as straight lines connecting the coasts. From top right going clockwise, freeways pass through Oakland, Hayward, Fremont, San Jose, Palo Alto, Redwood City, San Mateo and San Francisco.

The bright lights of the cities are themselves surrounded by natural parks. Past the coastal Eastern Bay Regional Parks to the right, the cities of Pleasanton and Walnut Creek keep the dark wilderness at bay with their street lighting. To the left, apart from the Half Moon Bay Airport on the coast, the blackness of the Pacific Ocean prevails. This image was taken on December 23, 2012 from the International Space Station.

The European Space Agency developed an automatic camera tripod that compensates for the speed of the Space Station flying at 28,800 km/h to take sharper pictures at night.

Assembly of the International Space Station – Wikipedia …

Posted on by

Assembly of the International Space Station (ISS) is about the construction of an Earth-orbiting space station. Zarya, the first ISS module, was launched by a Proton rocket on 20 November 1998. The STS-88 shuttle mission followed two weeks after Zarya was launched, bringing Unity, the first of three node modules, and connecting it to Zarya. This bare 2-module core of the ISS remained unmanned for the next one and a half years, until in July 2000 the Russian module Zvezda was added, allowing a minimum crew of two astronauts or cosmonauts to be on the ISS permanently.

The ISS has a planned pressurized volume of approximately 1,000 cubic meters, a mass of approximately 400,000 kilograms, approximately 100 kilowatts of power output, a truss 108.4 meters long, modules 74 meters long, and a crew of six. Building the complete station will require more than 40 assembly flights. As of March 2011, 26 Space Shuttle flights have docked with ISS to add elements, and 9 other Shuttle flights have flown logistics-servicing missions to ISS without adding major external elements. These 35 Shuttle missions include 9 SpaceHab and 10 MPLM logistics-servicing missions in various combinations. The last two planned Shuttle flights are due to add one of the two final elements of ISS, followed by one last Proton launch with the planned delivery of the ERA. Other assembly flights have consisted of modules lifted by the Russian Proton rocket or in the case of Pirs and Poisk by a Soyuz-U rocket.[dated info]

Some of the larger modules include:

The space station is located in orbit around the Earth at an altitude of approximately 360km (220mi), a type of orbit usually termed low Earth orbit (the actual height varies over time by several kilometers due to atmospheric drag and reboosts). It orbits Earth in a period of about 90 minutes; by August 2007 it had completed more than 50,000 orbits since launch of Zarya on 20 November 1998.

A total of 14 main pressurized modules are scheduled to be part of the ISS by its completion date in 2010.[1] A number of smaller pressurized sections will be adjunct to them (Soyuz spacecraft (permanently 2 as lifeboats - 6 months rotations), Progress transporters (2 or more), the Quest and Pirs airlocks, as well as periodically the Multi-Purpose Logistics Module, the Automated Transfer Vehicle and the H-II Transfer Vehicle).

The ISS, when completed, will consist of a set of communicating pressurized modules connected to a truss, on which four large pairs of photovoltaic modules (solar panels) are attached. The pressurized modules and the truss will be perpendicular: the truss spanning from starboard to port and the habitable zone extending on the aft-forward axis. Although during the construction the station attitude may vary, when all four photovoltaic modules are in their definitive position the aft-forward axis will be parallel to the velocity vector.[2]

In addition to the assembly and utilization flights, approximately 30 Progress spacecraft flights are required to provide logistics until 2010. Experimental equipment, fuel and consumables are and will be delivered by all vehicles visiting the ISS: the Shuttle, the SpaceX Dragon, the Russian Progress, the European ATV and the Japanese HTV, and space station downmass will be carried back to Earth facilities on both the Shuttle and the Dragon.[3]

At one point, there was some uncertainty over the future of the ISS. The Space Shuttle Columbia disaster on 1 February 2003, the subsequent two and a half-year suspension of the U.S. Space Shuttle program, followed by problems with resuming flight operations in 2005, were major obstacles.

The Space Shuttle program resumed flight on 26 July 2005, with the STS-114 mission of Discovery. This mission to the ISS was intended both to test new safety measures implemented since the Columbia disaster, and to deliver supplies to the station. Although the mission succeeded safely, it was not without risk; foam was shed by the external tank, leading NASA to announce future missions would be grounded until this issue was resolved.

Between the Columbia disaster and the resumption of Shuttle launches, crew exchanges were carried out solely using the Russian Soyuz spacecraft. Starting with Expedition 7, two-astronaut caretaker crews were launched in contrast to the previously launched crews of three. Because the ISS had not been visited by a shuttle for an extended period, a larger than planned amount of waste accumulated, temporarily hindering station operations in 2004. However Progress transports and the STS-114 shuttle flight took care of this problem.

Movie Synopsis: Space Station 76 is a refueling satellite near an alternate-reality Earth, circa 1976. Jessica arrives to serve as the station's new first mate. While she narrates a piece about how she likes the predictability of asteroids, some placidly drifting asteroids are shown colliding in chain-reaction fashion. While at first the station appears normal and the people friendly, Jessica soon discovers that the people on board have issues due to the isolation and stress of being cooped up with one another in a relatively small space far from Earth. This is in addition the usual problems people struggle with, such as infidelity, loneliness, depression, and drug abuse. She tries to make friends and fit in, but, unable to connect meaningfully with anyone, she becomes lonely. She's baffled and disillusioned by the stiff and irritable Captain Glenn, who harbors secrets of his own. She finds herself drawn to Ted, a lonely, married crewman, and his 7 year-old daughter, Sunshine. Ted yearns to reconnect with his unhappy, medicated wife, Misty, but she's too far gone to respond and is driving him away. His daughter Sunshine contends with her unhappy, mentally ill mother and her own isolation issues. Events finally come to a head at a Christmas party when a rapidly unhinging Misty decides everyone needs to play the "Truth Game." Just when it seems like everything's falling apart, a celestial event shakes everyone to their core, reminding them what their real priorities in life should be.. Or maybe Space Station 76.

How Space Station Tech Is Helping the Fight Against Cancer

Posted on by

One of the tools used in the fight against cancer is, quite literally, out of this world.

Research performed on the International Space Station and its predecessors, along with technology developed initially for work in space, play important roles in understanding the disease and improving treatments.

When the Soviet Union launched Salyut 1, the first space station, into orbit in the 1970s, humans began spending more and more time in extremely low-gravity environments. On the International Space Station today, gravity ranges from 1,000 to 1,000,000 times less than the force experienced on Earth. These weightless environments are also known as "microgravity" environments, offering an invaluable platform for cancer research in space.

In a recent article published in the journal Nature Reviews Cancer, cell biologist Jeanne Becker, of Nano3D biosciences in Houston, explored how microgravity environments in space stations of the past and present allow biologists to study the cells in three-dimensional growth environments similar to those experienced in the human body. [Space Shuttle Science: What It Did for You]

On Earth, gravityflattens the cells in a lab, but in space they retain their rounded shapes. At the same time, in microgravity, the cells arrange themselves into three-dimensional groupings, or aggregates, that bear a strong resemblance to what happens inside the human body. Becker was the principle investigatorfor a space station experiment that focused on ovarian cancer cells, according to a NASA statement.

Since 2003, the Japan Aerospace Exploration Agency (JAXA), has studied the high-quality crystals formed by protein molecules in space, where microgravity no longer causes flows based on density differences and the sinking of heavier particles. The resulting orderly formation of protein crystals may hold the key to treating diseases. One newfound protein, H-PGDS, plays a useful role in the treatment of muscular dystrophy.

Another study, Cellbox-Thyroid, examines cancer at a cellular level. Building on findings from a previous investigation, Cellbox-Thyroid studies the spherical structure of cancer cells in microgravity and how they spread, potentially providing an improved understanding on what drives the cells.

Not all space research requires a station.

One team of scientists, led by Daniela Grimm, a researcher with the Laboratory of Space Medicine and Space Pharmacology at Aarhus University in Denmark, studied the Science in Microgravity Box (SIMBOX) on the Shenzhou 8 spacecraft, an unmanned Chinese spacecraft that docked with that country's Tiangong 1 space module in 2011. The team determined that some tumors seem to become less aggressive in microgravity than they are on Earth. Grimm and her colleagues continue to search for as many genes and proteins as possible that are affected by microgravity. [10 Do's and Don'ts to Reduce Your Risk of Cancer]

Doctors have plenty of experience fighting cancer on the ground. But astronauts in space are constantly bombarded by cosmic rays, a different form of radiation than is experienced on Earth, where gamma and X-ray radiation prevail. The different types of radiation can produce different changes in human DNA, the genetic material present in nearly every cell in the body.
