On Sunday, Nov. 15, four astronauts ascended to space as part of the NASA and SpaceX joint Crew-1 mission to the International Space Station . As they left Earth’s atmosphere , they were greeted by the inky darkness of space. Or were they?
According to a new study scheduled to be published in The Astrophysical Journal, scientists have determined that outer space isn’t pitch black at all — it’s actually filled with light. While we all know that stars emit plenty of visible light, we’ve generally assumed that space, as a whole, is completely dark in the absence of stars. And it is definitely dark, but apparently, it’s not that dark.

Hear a sound bite from NASA's Perseverance as it travels along the final frontier
You can now hear an audio sound bite from NASA's Perseverance as it travels through space. Pictured here is an artist's rendition of the Perseverance with the landing microphone attached.

"As great as it is to pick up a little audio on spacecraft operations in-flight, the sound file has a more important meaning," Dave Gruel, lead engineer for Mars 2020's EDL Camera and Microphone subsystem said. "It means that our system is working and ready to try to record some of the sound and fury of a Mars landing."
SpaceX will have nearly 1,000 Starlink satellites orbiting Earth after rocket launch Sunday |
This comes a day after a U.S.-European satellite designed to extend a decades-long measurement of global sea surface heights was launched into Earth orbit on a SpaceX Falcon 9 rocket from California.
The Sentinel-6 Michael Freilich satellite is named for a former NASA official who had a key role in developing space-based oceanography. Its main instrument is an extremely accurate radar altimeter that will bounce signals off the surface of the oceans.
What does the 2020 presidential election mean for space exploration? | Space
President Donald Trump and former Vice President Joe Biden haven't talked much about the final frontier during the 2020 race, which peaks today (Nov. 3) with Election Day. (That moniker is a bit misleading, however, given that more than 90 million people cast their ballots early and multiple states will be counting votes for days afterward.)

NASA is working to achieve these goals via its Artemis program of crewed lunar exploration, which aims to establish a sustainable human presence on and around the moon by 2028. The first crewed Artemis landing is currently targeted for 2024, an ambitious timeline Pence announced in 2019.

SpaceX's Launch Continues What Gemini Astronauts Started | Time
Fifty-four years earlier to the day, in 1966, the pair splashed down in the Atlantic Ocean northeast of Turks and Caicos after a nearly four day, 59-orbit mission in their Gemini 12 spacecraft. The flight was close to flawless. The crew successfully docked with an uncrewed Agena spacecraft, and Aldrin logged more than five hours outside the Gemini over the course of three separate spacewalks. The tenth and final flight of the Gemini series, it was by any measure a perfect capstone.
Listen to Space Travel of NASA's Perseverance Vehicle - Somag News
NASA’s spacecraft named Perseverance is currently continuing its journey towards Mars. It is possible to listen to the sounds of the vehicle, which will arrive at the red planet in about 3 months.
Sound does not propagate in space. Since there is no air or other vibrating material, there is no sound. Still, it is possible to heed the journey of NASA’s spacecraft named Perseverance.
The Perseverance vehicle was developed for use in various researches on the Martian surface. NASA sent this vehicle to the red planet in recent months. The vehicle is expected to travel in space for approximately 3 months.
