Proposed NASA Mission Would Visit Neptune’s Curious Moon Triton

PASADENA, Calif. (NASA PR) — When NASA’s Voyager 2 spacecraft flew by Neptune’s strange moon Triton three decades ago, it wrote a planetary science cliffhanger.

Voyager 2 is the only spacecraft ever to have flown past Neptune, and it left a lot of unanswered questions. The views were as stunning as they were puzzling, revealing massive, dark plumes of icy material spraying out from Triton‘s surface. But how? Images showed that the icy landscape was young and had been resurfaced over and over with fresh material. But what material, and from where?

NASA’s Deep Space Antenna Upgrades to Affect Voyager Communications

The antenna enhancements will improve future spacecraft communications, but during the upgrades, Voyager 2 will not be able to receive new commands from Earth.


PASADENA, Calif. (NASA PR) — Starting in early March, NASA’s Voyager 2 will quietly coast through interstellar space without receiving commands from Earth. That’s because the Voyager’s primary means of communication, the Deep Space Network’s 70-meter-wide (230-feet-wide) radio antenna in Canberra, Australia, will be undergoing critical upgrades for about 11 months. During this time, the Voyager team will still be able to receive science data from Voyager 2 on its mission to explore the outermost edge of the Sun’s domain and beyond.

NASA Devises New Plan to Keep Voyager Spacecraft Operating Longer

PASADENA, Calif. (NASA/JPL-Caltech PR) — With careful planning and dashes of creativity, engineers have been able to keep NASA’s Voyager 1 and 2 spacecraft flying for nearly 42 years — longer than any other spacecraft in history. To ensure that these vintage robots continue to return the best science data possible from the frontiers of space, mission engineers are implementing a new plan to manage them. And that involves making difficult choices, particularly about instruments and thrusters.

Voyager 2 Enters Interstellar Space

PASADENA, Calif. (NASA/JPL-Caltech PR) — 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.

WASHINGTON (NASA PR) — NASA researchers will present new findings on a wide range of Earth and space science topics at the annual meeting of the American Geophysical Union (AGU), Dec. 10-14 in Washington. NASA-related briefings will stream live on the agency’s website.

Briefing topics include: the latest findings from the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-Rex) mission to asteroid Bennu and the new Ice, Cloud and land Elevation Satellite-2 (ICESat-2) Earth-observing mission; the lingering impact of Hurricane Maria on Puerto Rico; and an update on Voyager 2 at the edge of the solar system.

Agency scientists, and their colleagues who use NASA research capabilities, also will present noteworthy findings during scientific sessions that are open to registered media.

Details on NASA presentations will be updated online throughout the week. For a complete and up-to-date schedule of briefings and media participation information, visit:

NASA Voyager 2 Could Be Nearing Interstellar Space

This graphic shows the position of the Voyager 1 and Voyager 2 probes relative to the heliosphere, a protective bubble created by the Sun that extends well past the orbit of Pluto. Voyager 1 crossed the heliopause, or the edge of the heliosphere, in 2012. Voyager 2 is still in the heliosheath, or the outermost part of the heliosphere. (Credits: NASA/JPL-Caltech)

PASADENA, Calif. (NASA PR) — NASA’s Voyager 2 probe, currently on a journey toward interstellar space, has detected an increase in cosmic rays that originate outside our solar system. Launched in 1977, Voyager 2 is a little less than 11 billion miles (about 17.7 billion kilometers) from Earth, or more than 118 times the distance from Earth to the Sun.

A Look Back at the Space Year That Was

I realize it’s a bit late, but here’s a look back at the major developments in space in 2017.

I know that I’m probably forgetting something, or several somethings or someones. Fortunately, I have eagle-eyed readers who really seem to enjoy telling me just how much I’ve screwed up. Some of them a little too much….

So, have at it!  Do your worst, eagle-eyed readers!
