Like the Mary Celeste, the International Space Station (ISS) could be floating empty, devoid of humans by November. However, unlike the Mary Celeste, we'll know exactly what happened to the crew.

In the wake of the Russian Progress vehicle crash shortly after launch on Aug. 24, a chain of events has been set into motion that could result in the decision not to fly astronauts into orbit. If this happens, the ISS will be temporarily mothballed before the end of the year to avoid landing astronauts during the harsh Kazakh winter.

So why are there concerns about getting astronauts into orbit when the failure happened to the rocket carrying an unmanned vehicle?

Well, the Soyuz-U rocket's third stage is almost identical to equipment used on the Soyuz-FG booster used to propel manned Soyuz vehicles to the ISS. Yes, those are the same taxi rides NASA now depends on to get U.S. astronauts to the orbiting outpost.

In fact, since the retirement of the shuttle fleet, it is currently the only human-rated ride into space on the planet.

According to Spaceflight Now, the Russian space agency Roscosmos is carrying out an inquiry into the agency's plans for their manned spaceflight program, space manufacturing quality and a board has been set up to recommend corrective actions.
