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

same engineers who sent high-definition (HD) cameras, 3D cameras, and a camera
capable of recording 4K footage to the space station have now delivered a new
8K camera by RED – capable of recording images
with four times the
resolution than the previous camera offered.
Let’s compare this
camera to others: The Helium 8K camera is capable of
shooting at resolutions ranging from conventional HDTV up to 8K, specifically 8192
x 4320 pixels. By comparison, the average HD consumer television displays up to
1920 x 1080 pixels of resolution, and digital cinemas typically project 2K to 4K.

the 8K resolutions are optimal for showing on movie screens, NASA video editors
are working on space station footage for public viewing on YouTube. Viewers will
be able to watch high-resolution footage from inside and outside the orbiting
laboratory right on their computer screens. Viewers will need a screen capable
of displaying 8K resolution for the full effect, but the imagery still trumps
that of standard cameras. RED videos and pictures are shot at a higher fidelity
and then down-converted, meaning much more information is captured in the
images, which results in higher-quality playback, even if viewers don’t have an
Earth is a complex, dynamic system. For 60 years, we have studied our changing planet, and our understanding continues to expand with the use of new technologies. With data from satellites, instruments on the International Space Station, airborne missions, balloons, and observations from ships and on land, we track changes to land, water, ice, and the atmosphere. Application of our Earth observations help improve life now and for future generations. Since we opened for business on Oct. 1, 1958, our history tells a story of exploration, innovation and discoveries. The next 60 years, that story continues. Learn more: https://www.nasa.gov/60
It is part of the human spirit to explore. During 60 years, we have selected 350 people as astronauts to lead the way. For nearly two decades, humans have been living and working aboard the International Space Station in low-Earth orbit to enable future missions forward to the Moon and on to Mars while also leading discoveries that improve life on Earth. Since we opened for business on Oct. 1, 1958, our history tells a story of exploration, innovation and discoveries. The next 60 years, that story continues. Learn more: https://www.nasa.gov/60
Technology drives exploration. For 60 years, we have advanced technology to meet the rigorous needs of our missions. From GPS navigation to water filtration systems, our technologies developed for space improve your daily life on Earth. We continue to innovate and explore.

Congress passed the National Aeronautics and Space Act, on July 16 and President Eisenhower signed it into law on July 29, 1958. We opened for business on Oct. 1, 1958, with T. Keith Glennan as our first administrator. Our history since then tells a story of exploration, innovation and discoveries. The next 60 years, that story continues. Learn more: https://www.nasa.gov/60
We asked real life astronauts YOUR questions! Was your submission sent to space?
Astronauts Drew Feustel & Ricky Arnold recently recorded answers to your questions in a VideoAnswer Time session. We collected your questions and sent them to space to be answered by the astronauts on Friday, May 18. We recorded their answers and will post them tomorrow, May 30, here on our Tumblr.
Andrew J. Feustel was selected by NASA in 2000. He has been assigned to Expedition 55/56, which launched in March 2018. The Lake Orion, Michigan native has a Ph.D. in the Geological Sciences, specializing in Seismology, and is a veteran of two spaceflights. Follow Feustel on Twitter and Instagram.
Richard R. Arnold II was selected as an astronaut by NASA in May 2004. The Maryland native worked in the marine sciences and as a teacher in his home state, as well as in countries such as Morocco, Saudi Arabia, and Indonesia. Follow Arnold on Twitter and Instagram.
Don’t forget check our Tumblr tomorrow at noon EDT to see if your question was answered by real-life astronauts in space.
