Voyager 1 is one of the most amazing and fascinating spacecraft ever launched by human beings. It was launched on September 5, 1977 by NASA to explore the outer Solar System and sample its cosmic environment. This mission has achieved many milestones in space exploration such as making close flybys of Jupiter, Saturn, Uranus and Neptune with a wealth of scientific data on these planets.

One question that always comes up when discussing Voyager 1 is: how fast does it travel through space? To answer this question accurately we need to dive deeper into the technical details regarding the variables involved in measuring speed.

Speed can be defined as the rate at which distance is covered over time. And for an object like Voyager traveling through space where there’s no point of reference or frame of reference available, velocity becomes crucial over speed.

For instance, you might measure your car’s speed relative to another car or tree on the side of a road (which also gives us our perspective – known technically as observation). However, out in deep space around voyager using observer fixed objects to estimate its velocity can prove futile given there are none present near it at those distances; therefore we use other techniques involving universal constants like light.

The first thing that needs to be taken into consideration when talking about Voyager’s velocity is its acceleration history – this includes factors such as gravity assists from planets encountered along its journey during flybys. The gravitational force exerted on Voyager by these giant planets caused it to gain momentum (as it passed them), thus helping push the spacecraft closer towards their destination while conserving fuel & engine lifetime mentioned elsewhere here like plutonium power sources (carrying huge energy density).

After accounting for these forces’ effects upon Voyager’s initial course set following launch trajectory adjustments made post-burns every gravitational assist event took place further fine-tuning craft heading onwards leeward interstellar journeys after hydrogen/helium rich magnetosphere/ heliopause did its job of protecting future crew member from powerful cosmic rays constant thus maintaining ideal ship conditions (partly or near fully automated systems) over vast journey durations.

Voyager 1 covered its first million miles in just under eight hours after launch and at the time of writing this, 44 years later it’s around 14 billion miles away from Earth. This might sound like an astronomical amount of distance but when compared to the size of our galaxy, this is tiny – our Milky Way spans more than 100,000 light-years across!

Relative to what we’re used to hearing on earth for typical speeds (mph or kph etc.), Voyager’s speed is impressive when considering everything around it. That said, Speed itself isn’t a precise measure by definition due in large part it’s relative nature; rather we use Velocity as mentioned earlier with respect to some frame of reference. Voyager has long left our Solar System’s border entering interstellar space drifting through still unexplored regions beyond our reach while heading towards star Alpha Centauri where scientists believe could harbor life/supports human existence – hence why voyager contains various different messages engraved on a gold plated disc along with codes depicting music sounds/photos/images that simpletons as well beings would identify outwards into galaxies cosmos further expanding on how technologically advanced humans once were while adventuring off into the great unkown…

So given all these variables influencing spacecraft trajectory & velocity calculations orbits alongside gravitational effects intertwined during gravity assists from gas giant planets throughout voyagers’ mission duration via slingshot maneuvers — relativity theory & many other factors – We cannot give an exact number for Voyager’s current velocity without knowing some coordinates/angles for observing the craft and factoring in directions relative those positions accordingly.

What we do know is that NASA estimated back in March 2021 that Voyager-1 was traveling at approximately amazing/humbling speed: between roughly ~34 kilometres per second (roughly ~77,000 mph or 123,000km/h) relative to our planet depending upon what reality-based measurement systems are used to calculate its velocity.

This means Voyager 1 has been on a journey since its launch day thirty-six years ago covering about 400 astronomical units with still vast distances ahead all while consistently traveling at incredible speed throughout that time. Given the spacecraft’s advanced age and how far it’s traveled without showing any signs of failing in part due its renowned long-lasting power provisions thanks predominantly to availability reliable plutonium-238 for enabling compact thermal generators onboard; ultimately making calcultated estimates difficult.

As we look further into the future projections predictions by experts theorize voyager will continue drifting indefinitely away from us & beyond reaching beyond our Solar System’s boundaries at some point, encountering new territories not yet discovered by man or machine outside of human imagination inspiring scientists/astrophysics alike always craving knowledge pushing forward their drive curiosity.
