NASA's Voyager 2 Probe Enters Interstellar Space

For the second time in history, a human-made object has reached the space between the stars. NASA's Voyager 2 probe now has exited the heliosphere - the protective bubble of particles and magnetic fields created by the Sun.

Members of NASA's Voyager team will discuss the findings at a news conference at 11 a.m. EST (8 a.m. PST) today at the meeting of the American Geophysical Union (AGU) in Washington. The news conference will stream live on the agency's website.

Comparing data from different instruments aboard the trailblazing spacecraft, mission scientists determined the probe crossed the outer edge of the heliosphere on Nov. 5. This boundary, called the heliopause, is where the tenuous, hot solar wind meets the cold, dense interstellar medium. Its twin, Voyager 1, crossed this boundary in 2012, but Voyager 2 carries a working instrument that will provide first-of-its-kind observations of the nature of this gateway into interstellar space.

Voyager 2 now is slightly more than 11 billion miles (18 billion kilometers) from Earth. Mission operators still can communicate with Voyager 2 as it enters this new phase of its journey, but information - moving at the speed of light - takes about 16.5 hours to travel from the spacecraft to Earth. By comparison, light traveling from the Sun takes about eight minutes to reach Earth.

    I wonder what'd happen if voyager patches were publicly done online through github or something. I bet lots of really smart programmers would jump at the chance to push code to voyager.

    Yeah but within two weeks the Ruby on Rails code pushed by a millennial programmer would break because of a dependency problem and then the Voyager would be lost forever.

    It would be nice to look at... but meantime one could get a job. The requirements are assembler, Fortran (without numbers:) and, believe it or not, COBOL https://www.geek.com/news/nasa-seeks-programmer-fluent-in-60-year-old-languages-to-work-on-voyager-1638276/ [geek.com]

    I am, or should I say used to be, proficient in all.
