Did you know that facts related to voyager 2 mind-blowing technology?

Earlier this year, Voyager 2 shut down.

For those who forget, the Voyager program was an endeavor undertaken by NASA to launch two robotic probes into space.

These craft, taking advantage of a rare alignment of the planets, would travel to Neptune’s orbit and beyond, gathering significant data about our solar system along the way.

Incredibly, both Voyager 1 and 2 have successfully ventured to the edge of the solar system, crossing the edge of the heliosphere in 2012 and 2018 respectively.

But on January 25, Voyager 2 attempted to calibrate its magnetic field instrument and failed. Doing so caused the probe to try and draw on additional power, which triggered a failsafe that shut down its functionality.

See, NASA’s engineers recognized that the probes would be venturing far beyond the reach of the Sun’s rays, meaning that solar power would not be sufficient enough to keep them both running.

So, they fitted both of them with radioisotope thermoelectric generators (RTGs)s, which converts the heat from radioactive decay into electricity.

This is what’s been keeping the two probes operating for the past forty years.

But there’s a limited supply of fuel for the RTGs, which has forced NASA to gradually shut down parts of the probe over time.

That’s also why the failsafe exists: to prevent too much power getting used for anything that might be considered extraneous… like a failed calibration.

Incredibly, NASA’s engineers managed to diagnose the probe’s issue and bring it back online.

They essentially did this while the probe was over 11 billion miles away, making this a truly incredible feat. And it was by no means an easy task.

See, given the great distance, a singular command from the headquarters at Jet Propulsion Laboratory (JPL) takes 17 hours to travel to the craft, and 17 hours to make a return trip.

That means the engineers had to wait almost one-and-a-half days each time to see if they had been successful in a given step!

Make no mistake: the technology that we have today is undoubtedly incredible; but for the truly mind-blowing feats, one need not look farther than the feats of space travel.

Did you know Why no one invented a battery for smartphones which can last a few weeks?

18,000mAh Li-ion battery, it offered 50 days No one wanted it. This is the Energizer P18K Pop Smartphone… yup, a smartphone. With an 18,000mAh Li-ion battery, it offered 50 days of cellular standby time. Based on a mid-range MediaTek Helio P70 SOC and a moderate LCD resolution of 1080 x 2280 pixels, you might expect it to make it two weeks on a charge. My ZTE Axon 10 Pro manages a typical 3 days from a 4000mAhr battery, more DRAM, and a higher-end processor. That’s certainly brute-forcing it, but what other option do you have? iPhone 11 Pro is, by comparison This one, however, is real. This is the Blackview BV9100, which sports a 12000mAh built-in battery (labelled 13000mAh, but 12000mAh in testing), with 30W wired charging, in a rugged case. They sell this as an “outdoor smartphone.” It’s running the MediaTek Helio P35 processor, a low-end 8 core processor, all cores ARM Cortex A53, along with 4GiB RAM (LPDDR4X) and 64GB flash (eMMC). So certainly usable, and available for about ...

Did you know the fact behind Apple doesn't want to change their lightning port to USB type-C? 2020

Why doesn't Apple want to change their lighting port to USB type-C? Apple likes to control their entire product ecosystem. Part of this is financial: Apple gets about 30% of the profit on any item that goes onto an iPhone. That’s apps and media sold through the iTunes store, and its licensed hardware products. That 30% Royalty :- The Lightning Port is the means by which Apple enforces this for hardware products. There are patents that cover Lightning, and in order to legally sell a Lightning product, you have to pay Apple. There’s also a digital “tag” chip in a Lightning connector that tells iOS information about the device, so it knows what to do with that device. When you connect a device to a Lightning port, there’s a bit of power and a few signals used to identify the device. But aside from that, it does nothing. The ID chip describes the attached device, and enables the connections necessary (power, USB, etc) in order to support the attached device. So even something as simple...
