Topic: NASA’s Voyager 1 Spacecraft
Pasadena, CA – On October 29th, 2020 mission operators sent a series of commands to NASA’s Voyager 2 spacecraft for the first time since mid-March. The spacecraft has been flying solo while the 70-meter-wide (230-foot-wide) radio antenna used to talk to it has been offline for repairs and upgrades. Voyager 2 returned a signal confirming it had received the “call” and executed the commands without issue.
The call to Voyager 2 was a test of new hardware recently installed on Deep Space Station 43, the only dish in the world that can send commands to Voyager 2.
Washington, D.C. – For the first time, a spacecraft has sent back pictures of the sky from so far away that some stars appear to be in different positions than we’d see from Earth.
More than four billion miles from home and speeding toward interstellar space, NASA’s New Horizons has traveled so far that it now has a unique view of the nearest stars.
“It’s fair to say that New Horizons is looking at an alien sky, unlike what we see from Earth,” said Alan Stern, New Horizons principal investigator from Southwest Research Institute (SwRI) in Boulder, Colorado.
Pasadena, CA – Starting in early March, NASA’s Voyager 2 spacecraft 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.
Pasadena, CA – Engineers for NASA’s Voyager 2 spacecraft are working to return the mission to normal operating conditions after one of the spacecraft’s autonomous fault protection routines was triggered.
Multiple fault protection routines were programmed into both Voyager 1 and Voyager 2 in order to allow the spacecraft to automatically take actions to protect themselves if potentially harmful circumstances arise. At NASA’s Jet Propulsion Laboratory in Pasadena, California, engineers are still communicating with the spacecraft and receiving telemetry.
Pasadena, CA – On November 5th, 2018, NASA’s Voyager 2 became only the second spacecraft in history to leave the heliosphere – the protective bubble of particles and magnetic fields created by our Sun. At a distance of about 11 billion miles (18 billion kilometers) from Earth – well beyond the orbit of Pluto – Voyager 2 had entered interstellar space, or the region between stars.
Today, five new research papers in the journal Nature Astronomy describe what scientists observed during and since Voyager 2’s historic crossing.
Greenbelt, MD – NASA says that out at the boundary of our solar system, pressure runs high. This pressure, the force plasma, magnetic fields and particles like ions, cosmic rays and electrons exert on one another when they flow and collide, was recently measured by scientists in totality for the first time — and it was found to be greater than expected.
Using observations of galactic cosmic rays — a type of highly energetic particle — from NASA’s Voyager spacecraft scientists calculated the total pressure from particles in the outer region of the solar system, known as the heliosheath.
Pasadena, CA – NASA engineers have been able to keep Voyager 1 and 2 spacecrafts flying for nearly 42 years, with careful planning and dashes of creativity, far 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.
Pasadena, CA – The first definitive detection beyond our world of an internal magnetic field that changes over time was detected during NASA’s Juno mission to Jupiter. It’s a phenomenon called secular variation. The gas giant’s secular variation is most likely driven by the planet’s deep atmospheric winds, Juno determined.
The discovery will help scientists further understand Jupiter’s interior structure – including atmospheric dynamics – as well as changes in Earth’s magnetic field. A paper on the discovery was published today in the journal Nature Astronomy.
NASA Jet Propulsion Laboratory
Pasadena, CA – 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 10:00am CST (8:00am PST) on Monday, December 10th at the meeting of the American Geophysical Union (AGU) in Washington. The news conference will stream live on the agency’s website.
NASA’s Jet Propulsion Laboratory
Pasadena, CA – 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.
Since 2007 the probe has been traveling through the outermost layer of the heliosphere — the vast bubble around the Sun and the planets dominated by solar material and magnetic fields. Voyager scientists have been watching for the spacecraft to reach the outer boundary of the heliosphere, known as the heliopause. Once Voyager 2 exits the heliosphere, it will become the second human-made object, after Voyager 1, to enter interstellar space.
