NASA’s Voyager 1 First Spacecraft to Leave Solar System—Almost

NASA, NASA Voyager 1, Voyager 1 Leaving Solar System

The American Geophysical Union issued a press release on Wednesday morning announcing that NASA’s Voyager 1 spacecraft, which embarked on a journey to the outermost planets in 1977, finally left the solar system, making it the first man-made object to travel beyond it. However, about three hours later NASA issued another press release countering the AGU, saying that the Voyager team did not believe it left the solar system, reports The New York Times.

“It is the consensus of the Voyager science team that Voyager 1 has not yet left the solar system or reached interstellar space,” Voyager project scientist Edward C. Stone said.

Voyager 1 is about 11.3 billion miles from the sun, moving at the speed of 38,000 miles per hour and was believed to have left the solar system because of a sudden shift in cosmic rays hitting the spacecraft. Cosmic rays are high-energy particles that mainly originate outside of the solar system. On August 25, William R. Webber of New Mexico State University and Frank B. McDonald of the University of Maryland reported that the spacecraft recorded almost double the amount of rays from outside the solar system while the intensity of cosmic rays that had been trapped by the solar system dropped by 90 percent.

“Within just a few days, the heliospheric intensity of trapped radiation decreased, and the cosmic ray intensity went up as you would expect if it exited the heliosphere,” Professor Webber said.

According to Dr. Stone, cosmic rays would not be the indicator of the spacecraft reaching interstellar space, but rather a change in in the direction of the magnetic field. He claimed that Voyager 1 is just in a different part of the solar system called the helioclff.

There’s no doubt that Voyager 1 will one day leave the influence of the sun, it’s just not there yet.

The AGU subsequently released yet another statement with the headline: Voyager 1 has entered a new region of space.
