Silhouetted over Earth, the International Space Station (ISS) is seen on October 11th, 2000 in a configuration soon to be changed, once the approaching STS-92 crew adds its important new changes. If oriented with Earth's horizon on the left, the ISS elements, from the left, are Node 1 or Unity, the functional cargo block or Zarya, the service module or Zvezda and the Progress supply ship. In a matter of days, the crew went on to add the Z1 Truss structure and a third pressurized mating adapter. (NASA)

Pettit's arms and camera are visible in the reflection of his helmet visor. Astronaut Kenneth D. Bowersox, mission commander, is also visible in visor reflection, upper right. (NASA)

An overhead view of the exterior of the Space Shuttle Atlantis' crew cabin, part of its payload bay doors and docking system was provided by Expedition 16 crewmembers. Before docking with the International Space Station, astronaut Steve Frick, STS-122 commander, flew the shuttle through a roll pitch maneuver or basically a backflip to allow the space station crew a good view of Atlantis' heat shield. Using digital still cameras equipped with both 400 and 800 millimeter lenses, the ISS crewmembers took a number of photos of the shuttle's thermal protection system and sent them down to teams on the ground for analysis. Photo taken February 9th, 2008. (NASA)

Some information about Space Station

The Phantom Torso, seen here on May 13th, 2001 in the Destiny laboratory on the International Space Station (ISS), is designed to measure the effects of radiation on organs inside the body by using a torso that is similar to those used to train radiologists on Earth. The torso is equivalent in height and weight to an average adult male. It contains radiation detectors that will measure, in real-time, how much radiation the brain, thyroid, stomach, colon, and heart and lung area receive on a daily basis. The data will be used to determine how the body reacts to and shields its internal organs from radiation, which will be important for longer duration space flights. (NASA) 

Backdropped against a blanket of heavy cloud cover, the Russian-built FGB, also called Zarya, approaches the Space Shuttle Endeavour and the U.S.-built Node 1, also called Unity (foreground) on December 6th, 1998. Inside Endeavour's cabin, the STS-88 crew readied the remote manipulator system (RMS) for Zarya capture as they awaited the rendezvous. (NASA) 

Blanketing clouds form the backdrop for this 70mm scene of the connected Zarya and Unity modules after having been released from Endeavour's cargo bay a bit earlier on December 4th, 1998. Six crew members, who had earlier spent the majority of their on-duty mission time working on the tandem of space hardware, watched the joined modules from Endeavour in a survey and fly-around mode.

Astronaut Robert L. Curbeam, STS-98 mission specialist, was photographed by a member of the Expedition One crew in the newly installed Destiny laboratory during the second of three space walks on February 12th, 2001. Ahead of schedule, the astronauts connected several computer and electrical cables between the docking port and the lab; unveiled the lab's large, high-quality window (through which this photo was taken) and attached an exterior shutter; and repositioned a movable foot platform they had taken inside Atlantis on the first spacewalk for a slight adjustment.

Most Expensive Accidents in History PART - II

Challenger Explosion
The Space Shuttle Challenger was destroyed 73 seconds after takeoff due on January 28, 1986 due to a faulty O-ring. It failed to seal one of the joints, allowing pressurized gas to reach the outside. This in turn caused the external tank to dump its payload of liquid hydrogen causing a massive explosion. The cost of replacing the Space Shuttle was $2 billion in 1986 ($4.5 billion in today's dollars). The cost of investigation, problem correction, and replacement of lost equipment cost $450 million from 1986-1987 ($1 Billion in today's dollars).

Prestige Oil Spill
On November 13, 2002, the Prestige oil tanker was carrying 77,000 tons of heavy fuel oil when one of its twelve tanks burst during a storm off Galicia, Spain. Fearing that the ship would sink, the captain called for help from Spanish rescue workers, expecting them to take the ship into harbour. However, pressure from local authorities forced the captain to steer the ship away from the coast. The captain tried to get help from the French and Portuguese authorities, but they too ordered the ship away from their shores. The storm eventually took its toll on the ship resulting in the tanker splitting in half and releasing 20 million gallons oil into the sea.

According to a report by the Pontevedra Economist Board, the total cleanup cost $12 billion.

 
Space Shuttle Columbia

The Space Shuttle Columbia was the first space worthy shuttle in NASA's orbital fleet. It was destroyed during re-entry over Texas on February 1, 2003 after a hole was punctured in one of the wings during launch 16 days earlier. The original cost of the shuttle was $2 Billion in 1978. That comes out to $6.3 Billion in today's dollars. $500 million was spent on the investigation, making it the costliest aircraft accident investigation in history. The search and recovery of debris cost $300 million.
In the end, the total cost of the accident (not including replacement of the shuttle) came out to $13 Billion according to the American Institute of Aeronautics and Astronautics. 

Chernobyl


On April 26, 1986, the world witnessed the costliest accident in history. The Chernobyl disaster has been called the biggest socio-economic catastrophe in peacetime history. 50% of the area of Ukraine is in some way contaminated. Over 200,000 people had to be evacuated and resettled while 1.7 million people were directly affected by the disaster. The death toll attributed to Chernobyl, including people who died from cancer years later, is estimated at 125,000. The total costs including cleanup, resettlement, and compensation to victims has been estimated to be roughly $200 Billion. The cost of a new steel shelter for the Chernobyl nuclear plant will cost $2 billion alone. The accident was officially attributed to power plant operators who violated plant procedures and were ignorant of the safety requirements needed.
