After the capsule hooks up with the station 240 miles above the earth, astronauts plan to retrieve about 1, 000 pounds of provisions, including food and clothes.
Reports said ambulances could not get to the platform for two hours to evacuate the injured to hospital or retrieve the bodies because of the masses thronging the streets and the station.
Within hours, NASA will retrieve the science samples meticulously collected over the weeks and months by space station astronauts, as well as experiments that flew up with Dragon, such as flowering weeds and mouse stem cells.
