After the blaze of a SpaceX's 'Falcon 9' rocket booster, the American aviation regulator, FAA, has provisionally halted all launches of the affected spacecraft. This impediment may affect various upcoming space expeditions, such as 'Polaris Dawn'. In 'Polaris Dawn', four astronauts are planned to journey approximately 1,400 kilometers distant from Earth, spending several days there, with a spacewalk included.
