Professor Fisk discusses Voyager 1 in the Washington Post

Professor Len Fisk was recently quoted in a Washington Post article entitled, “Out there: NASA says its Voyager 1 probe has become first spacecraft to leave the solar system.”

According to the article, new data shows that the Voyager 1 spacecraft “plowed through the hot plasma bubble surrounding the planets and escaped the sun’s influence.” From NASA’s standpoint, this means the Voyager 1 spacecraft has gone beyond the solar system.

However, due to the absence of a change in magnetic field direction, Fisk is not convinced.

“It’s premature to judge,” Fisk told the Associated Press. “Can we wait a little while longer? Maybe this picture will clear up the farther we go.”

There is still plenty of time to wait for a clearer picture, as Voyager 1 and Voyager 2 will not run out of nuclear fuel until about 2025.
