Spaceflight

Astronauts have reported lights, flashes, particles, and objects seen near their spacecraft or Earth. Some observations have received possible explanations, while others are not detailed enough in the available documentation.

There is documentation of astronauts reporting objects or lights they could not identify at the time of observation. The term "unidentified" describes a lack of identification and does not prove that the object is an alien spacecraft.

The cause depends on the specific observation: in one case, flashes were attributed to a phenomenon occurring within the eye, while in other cases, explanations like water droplets or particles were suggested. Not all reports have a documented explanation.

Communication with spacecraft is typically done using radio waves. As the distance increases, the signal's travel time becomes significant, leading to the exploration of various ideas for communication and remote control.

Not continuously, like operating a vehicle nearby, because light and radio signals require time to travel between Earth and Mars. A document described on the site examined a communication concept that could reduce waiting time, but the mere examination of the idea does not indicate that it is operational.
