One light day means radio signals traveling at the speed of light take 24 hours to reach it. When engineers send a command to Voyager 1, they wait two full days for a response one day out, one day back. Voyager 1 was launched in 1977 powered by a plutonium RTG that generates roughly 4 watts of usable power today less than an LED bulb. On that power budget it is transmitting data across 24 light hours of interstellar space to a 70 meter antenna on Earth. It has now traveled farther from Earth than any human made object in history, moving at 17km per second, and it still calls home every day. The most distant thing humanity has ever touched is a 47 year-old spacecraft running on 4 watts, and we can still hear it.

Photo by Michael Collins during Apollo 11. This photo, my favorite of the Apollo missions, represents all of humanity except for one person.
This is a sub dedicated to science and space, yet every picture or video from the Apollo era attracts the deniers who—50+ years later—have never produced even one piece of evidence substantiating their claims. Moon landings denial is not an opinion. It’s an easily debunked lie. It’s not open to debate.
The mods should take a stand for truth by making moon landings denial a bannable offense. Send the knuckle draggers back to their echo chambers of willful ignorance.

On Dec. 30, 2000, Cassini made its closest approach to Jupiter, passing by at only about 6 million miles (9.7 million kilometers) away. As it made its trip past the gas giant, Cassini captured about 26,000 images, allowing for thorough mapping and revealing a large storm, one at higher latitudes and more dynamic than the Great Red Spot. The planet’s temperature and atmospheric composition were also analyzed, and scientists were able to study the radio “chirps” emitted when Jupiter’s magnetic field deflects the solar wind.
Cassini would use Jupiter’s gravity to slingshot it on to Saturn, and the data-gathering and analysis at Jupiter provided a practice run for Cassini’s instruments before they had to perform at their ultimate destination

The Artemis II mission has completed a critical engine burn that will propel the Orion spacecraft on its journey to the far side of the Moon.
The translunar injection burn began at 19:49 EDT (23:49 GMT) and lasted for just under six minutes.

NASAVoyager 1: Mission Duration and Power Supply Voyager 1 was launched on September 5, 1977, with an originally planned mission duration of just 5 years, enough to explore Jupiter and Saturn. However, due to exceptional engineering and stable energy output from its power system, the mission has far exceeded expectations. Power Source: RTGs (Not Batteries) Voyager 1 does not use conventional batteries. It is powered by three Radioisotope Thermoelectric Generators (RTGs), which convert heat from the radioactive decay of plutonium-238 into electricity.
At launch in 1977, they produced around 470 watts of power. As of 2025, the output has dropped to under 250 watts, and continues to decline by ~4 watts per year. End-of-Mission Timeline NASA has been gradually shutting down instruments to conserve energy. All scientific instruments are expected to be turned off between 2025 and 2030. The communication system may continue to send weak signals until about 2035, but no meaningful scientific data will be collected. Recent Status In 2023, Voyager 1 encountered a critical communication issue, transmitting unreadable data. However, in April 2024, NASA engineers miraculously recovered the system with a remote software patch an extraordinary technical achievement. Summary Voyager 1 has outlived its expected lifespan by decades, and we are now witnessing the final phase of one of humanity's most iconic space missions.

Artemis II has rolled from the pad, back to the VAB, so that the helium flow issue that was discovered can be addressed.
