Rabies Cause, Transmission of Rabies. Rabies Cause. Rabies virus is in the Rhabdoviridae family. The virus cannot live outside its host's body for more than a couple of seconds, but live virus has been found in animals that have been dead as long as 48 hours. Rabies usually is transmitted through infected saliva as a result of a bite from an infected animal. Rarely, it is transmitted by viral contamination of a fresh wound, through a scratch, or through contamination of a mucous membrane (i.e., eyes, nose, mouth). There have been reports of rabies being transmitted through the air in bat-infested caves.

This image of Earth (on the left) and the moon (on the right) was taken by JunoCam on the Juno spacecraft, three weeks after its August 5 launch. On August 26, 2011, the spacecraft was already almost 10 million kilometers away from the Earth-Moon system.
Artist's concept of Mariner 9, the first probe to orbit Mars. Image credit: NASA We received this question from fourth-grade students in Fresno, California. JPL's Homework Help page provides basic information and suggestions for further research. A probe is a spacecraft that travels through space to collect science information. Probes do not have astronauts. Probes send data back to Earth for scientists to study. The First Probes Sputnik 1 was the first probe to go into space. It was launched on Oct. 4, 1957, by the former Soviet Union. On Jan. 31, 1958, the United States sent a probe called Explorer 1 into space. These first probes studied Earth from space. They also learned what it's like to be in space. This was the beginning of the Space Race between the United States and Soviet Union.
