At our current distance from the Sun, solar panels are all but useless – so we use something called radioisotope thermoelectric generators (RTGs) for power.
Each spacecraft is equipped with three RTGs, and current power output is about 220 watts for V1 and 223 watts for V2.
ALT A Multi-Hundred Watt Radioisotope Thermoelectric Generator (RTG) used on NASA's Voyager spacecraft. The cylindrical device is mounted vertically in a testing rig, with two dark-colored finned sections for heat dissipation and various wires and connectors attached. The RTG is shown indoors, in a clean lab environment with cables on the floor and industrial equipment in the background.

Here’s the mustachioed @ulalaunch leader @torybruno explaining the rationale for selecting the “dominator” Atlas V configuration for the #Mars2020 launch yesterday. Give it a listen and you’re gonna learn something. That dude is a national treasure. 🚀

318 gigatons.
That’s how much ice is lost every year from Antarctica and Greenland’s ice sheets, according to new science from @NASA_Ice's #ICESat2. go.nasa.gov/3cb0bCC
But… how much ice is that, really? 🤔
RocketSTEM retweeted
Let's say 🧊= a gigaton of ice.
🧊 would be enough to cover NYC’s Central Park in ice past the top of the Chrysler Building. When melted, it would fill 400,000 Olympic-sized swimming pools.
Each year from 2003 to 2019, Greenland lost 200 🧊s. Antarctica lost 118 🧊s.

NASA Free E-books download a copy or two to get through these increasingly rainy days and extended nights....not all doom and gloom only another 71 sleeps until Christmas (6,122,243 seconds) and counting!
With the 50th anniversary season of the Apollo missions upon us it might be time to brush up on the details. Try one of our free e-Books like “Where No Man Has Gone Before: A History of Apollo Lunar Exploration Missions” at (PDF): go.nasa.gov/2RNsNYU #Apollo50

Riding a rocket to space actually uses up less fuel than a transatlantic passenger flight. Our Soyuz carries ~77t of Kerosene fuel, the rest is Oxygen. The trick is to burn it quickly: these engines spit out 20 Gigawatts - equiv to 10 large nuclear power stations - for 2 mins.

Engineers at @NASAJPL have devised a new way for @MarsCuriosity rover to drill on the Red Planet since its drill stopped working reliably. I'm impressed by their innovation, read about it here: go.nasa.gov/2oJfMCu
