Is an unknown force having an influence (1) on Pioneer 10 and 11, NASA’soldest space probes? The probes have been travelling through space forover thirty years, but scientists have now (2) come to the conclusion thattheir current position does not correspond (3) to the predictions of wherethey should be. The probes appear to be (4 under the control of somethingother than the sun’s gravity. Scientists are unsure of the cause(5) of the probes’ slowness, but have narrowed (6) down the possibilities tothree main options. They (7) put forward their suggestions at a conferencethis week. It is possible, but unlikely, (8) that both probes aremalfunctioning in the same way at the same time; our understanding ofgravity may be wrong, or an unknown force in the universe is (9) probably the cause of adifference to the speed of the craft. Scientists say they will need tocarry (10) out more research before they can determine what the cause is.
