#NASA Turns Off Two Voyager Science Instruments To Extend Mission
#Voyager1's cosmic ray subsystem – a suite of three telescopes designed to study cosmic rays, including protons from the galaxy and the Sun, by measuring their energy and flux – was shut down last week. #Voyager2's low-energy charged particle instrument is due for deactivation later this month.

Technology built by government bureaucracy on a budget. Continues to defy expectations nearly five decades on. musk & trump will never make America great again. They have no idea what it takes.

This isn't a call to return to the 60s or 70s or anytime in the past — but you don't make progress by denying science; destroying progress; instilling fear; by cruel, vengeful, stupid leadership.

Heute vor 35 Jahren ist von der Raumsonde #Voyager1 auf Anregung von Carl Sagan ein "Familienfoto" geschossen worden, da die Planeten in einer einzigartigen Konstellation standen.
Also hat man am 14.2.1990 Voyager 1 gedreht und mehrere Fotos machen lassen. Die NASA hat die dann zu einem "Familienfoto" zusammengebaut.
Man sieht die Erde als kleinen blassen Punkt. Kaum sichtbar, ein Himmelskörper unter vielen. Und doch ist es unserer.

Tomorrow is the 35th anniversary of the #PaleBlueDot.

Both #Voyager1 and #Voyager2 are now past the "edge" of our solar system and traveling into interstellar space. Mission operators expect to stop receiving data from their science instruments this year, though estimates on how long they can continue transmitting status messages range as far out as 2036.

Joining them in escaping our solar system is #NewHorizons, which is currently traveling through the Kuiper belt, along with the now-derelict #Pioneer10 and #Pioneer11 probes.

Here's the full image of Earth. From the great distance that #Voyager1 had traveled (6 billion kilometers), you can just barely see our planet as a pale, blue dot amid one of the shafts of sunlight on the camera sensor.

On February 14th, 1990, at the Jet Propulsion Laboratory (#JPL) in Pasadena, California, the operators of #Voyager1 were preparing to shut down the probe's camera system for the final time. Since launching in 1977, the spacecraft had performed close flybys of Jupiter and Saturn and was using its kinetic energy from the gravitational slingshot to head toward the edge of our solar system, the so-called "termination shock" where the solar wind meets interstellar space. Out so far from everything, and with dwindling electrical output from the plutonium generator, it didn’t make much sense to keep the camera operating and consuming power with nothing left to see.

There WAS one final thing left to see, however; the spacecraft’s distant position allowed it a unique view of our entire solar system. Recognizing this, the mission planners decided that before they shut down the camera system for good, Voyager 1 would look back and take one last series of photos: a so-called "family portrait" of every planet together.

Here is the result:

“The Solar System ‘family portrait’ is the final series of 60 images captured by NASA’s Voyager 1 that show six of our solar system’s planets. It remains the first and only time — so far — a spacecraft has attempted to photograph our home solar system. Only three spacecraft have been capable of making such an observation from such a distance: Voyager 1, Voyager 2 and New Horizons.” - NASA / JPL-Caltech

Happy Space Science Sunday! Did you know that Voyager 1 is the first man-made object to travel past the heliosphere, a protective area of magnetic energy and particles generated by the Sun. It crossed this boundary into interstellar space in 2012. Miraculously, the spacecraft, which launched in 1977, is still sending data back to Earth. While there have been some technical difficulties, like communication issues and power limitations due to the decay of its radioactive power source, the team behind Voyager 1 remains committed to maintaining the project and gathering data for as long as possible.

Amateurastronomen vinden Voyager 1 met de Dwingeloo radiotelescoop

De Dwingeloo-telescoop, die is ontworpen om signalen op lage frequenties waar te nemen, ontdekte eerder dit jaar het verste door mensen bereikte ruimtevaartuig toen die in de problemen kwam.

New observations of the most volcanic world in our solar system solve a mystery that began with Voyager 1.

From @CNN: "Similar in size to Earth’s moon, [Jupiter's moon] Io has an estimated 400 volcanoes that continuously release plumes and lava that coat that moon’s surface."

The 25m Dwingeloo radio telescope (owned by ASTRON) has been operating since '50s. Recently, it has been used more by amateurs and pro-am radio astronomers.

Excitingly, they picked up the Voyager 1 signal.

Voyager 1 is ~25 billion km away! (~4 x Pluto distance)

Why this is neat?

Well, the Voyagers are so far away (human's furthest objects) that we need the biggest telescopes in the world (the Deep Space Network) to normally communicate with them. Those are big 70m dishes, so much larger gain.

A 25m dish, and the work of amateurs is a really nice story!

And to give you a scale of the signal power .... the signal from your home wi-fi is billions of times stronger (I think ~10 billion IIRC) than the signal Earth receives from Voyager spacecrafts. It's incredibly feeble, so detecting it is a big feat!

Well done to this team!

A plot showing frequency offset on x-axis and power in dB on the y-axis. The data shows a radio signal with a lot of noise as the main component, and a single spike rising to 61 dB. This is the signal of the Voyager 1 spacecraft.
