Last week’s Soyuz crash was just the latest in a series of embarrassing mishaps for Russia’s space industry, which is plagued by quality problems and an ageing workforce. With no other way to get astronauts into orbit, the operation of the International Space Station is now in question.
The people in the Altai Mountains of Siberia (where the crash occurred) are regarded as frugal and tough. In late summer, many live from harvesting berries and cedar nuts.
They are also used to having burned-out rocket stages crash in the wilderness after spacecraft launches. When, in the middle of last week, a large ball of fire was seen in the sky above the taiga, residents of the village of Karakoksha were not alarmed. They apparently just went back to sleep.
After a malfunction, a Russian Soyuz rocket had crashed along with an unmanned cargo spacecraft named Progress. The explosion was heard even 100 kilometers (62 miles) away.
This accident couldn’t have come at a worst time. It shuttered public confidence in the aging Russian technology which is crucial to the future of manned spaceflight since NASA shut down the Space Shuttle program in July. Russia remains the only country that is able to regularly put humans into space.
Permanent operation of the International Space Station (ISS) is now impossible without the Soyuz rocket, which went into service in its current form in 1973 and had previously been the most reliable rocket of all time.
Until officials figure out what went wrong with Russia’s essential Soyuz rockets, there will be no way to launch any more astronauts before the current residents have to leave in mid-November.
Abandoning the space station, even for a short period, would be an unpleasant last resort for the world’s five space agencies that have spent decades working on the project. Astronauts have been living aboard the space station since 2000, and the goal is to keep it going until 2020.
Even if the space shuttles still were flying, space station crews still would need Soyuz-launched capsules to serve as lifeboats, Suffredini said. The capsules are certified for no more than 6 1/2 months in space, thus the need to regularly rotate crews. Complicating matters is the need to land the capsules during daylight hours in Kazakhstan, resulting in weeks of blackout periods.
NASA wants American private companies to take over crew hauls, but that’s three to five years away at best. Until then, Soyuz capsules are the only means of transporting astronauts to the space station.
What is your opinion? Do you think that International Space Station will be abandoned?

The last shuttle has launched. NASA’s shuttle program is officially over. Now, after 4 decades, a lot of us left wondering if it was truly successful and whether or not it was worth the tremendous cost of $200 billion. Let us review the facts first.
What is a space shuttle? The Space Shuttle is a reusable launch system and orbital spacecraft operated by the U.S. National Aeronautics and Space Administration (NASA) for human spaceflight missions. The system combines rocket launch, orbital spacecraft, and re-entry spaceplane with modular add-ons.
How was the shuttle program started?
Watch the video of shuttle through the ages.
In 1968, NASA officially began work on what was then known as the Integrated Launch and Re-entry Vehicle (ILRV). At the same time, NASA held a separate Space Shuttle Main Engine (SSME) competition. NASA offices in Houston and Huntsville jointly issued a Request for Proposal (RFP) for ILRV studies to design a spacecraft that could deliver a payload to orbit but also re-enter theatmosphere and fly back to Earth. One of the responses was for a two-stage design, featuring a large booster and a small orbiter, called the DC-3.
In 1969, President Richard Nixon decided to proceed with Space Shuttle development. In August 1973, the X-24B proved that an unpowered spaceplane could re-enter Earth’s atmosphere for a horizontal landing.
It was planned that the flight rate will be around 48 shuttle flights per year, at a marginal cost per launch of something like $15 million.
How many shuttles were built?SixEnterprise (OV-101) was not built for orbital space flight, and was used only for testing gliding and landing.
Columbia (OV-102) broke apart during re-entry in 2003
Challenger (OV-099) disintegrated 73 seconds after launch in 1986
Discovery(OV-103)Atlantis (OV-104)Endeavour (OV-105) was built as a replacement for Challenger from structural spare components.
What were the costs involved?
One Space Shuttle launch costs around $450 million.
Average cost per flight of about US$1.5 billion
Average cost per person launched into space $200-$250 million
Total program cost $200 billion
What are the results?
The shuttles have flown about four times a year (originally planned 48 times per year).
The shuttles were also grounded for years after seven years after Challenger and Columbia accidents that took the lives of 14 people.
U.S. to forged international partnerships to build a huge, orbiting space station where astronauts can live in comfort for multiple months.
U.S. remains the world leader in spaceflight.
The shuttle gave the country a very capable work vehicle to go into low Earth orbit and do everything from carrying experiments there to launching satellites from there, to building space stations, to building telescopes like Hubble. It was a multipurpose work vehicle.
From now on the work of the shuttle will be done by private companies who are developing new rockets and capsules for quick trips up close to Earth, like to the orbiting station — and promising to usher in a new era that will make space more accessible than ever before.
The main remaining questions
Will the commercial companies be able to provide reliable space transportation services to the Space Station ?
If yes, which company has the best chance of succeeding?
