NASA is Studying a Planning to Build 1 Kilometer Giant Radio Telescope Inside a Lunar Crater Shielded From Earth's Radio Noise...

🚨NASA is supporting early-stage research into a bold idea: placing a radio telescope on the Moon’s far side. Unlike Earth, the lunar far side is naturally protected from much of the radio noise produced by satellites, spacecraft, and technology on our planet.

⸻

📡 That radio silence could open a completely new window on the universe. A large array on the Moon could observe extremely long radio wavelengths that are difficult—or impossible—to study from Earth because of terrestrial interference and Earth’s ionosphere.

⸻

🌌 One of the biggest scientific goals would be studying the Universe’s “Cosmic Dark Ages.” This was the period after the Big Bang but before the first stars and galaxies formed. Astronomers could search for the faint 21-centimeter signal from neutral hydrogen to investigate how the early Universe evolved.

⸻

🔭 Several lunar radio observatory concepts are being investigated, including FARSIDE, MoonRISE, FIORE, FarView, and the Lunar Crater Radio Telescope. Some concepts propose placing antennas across the lunar surface, while others envision using a natural crater as a giant radio dish.

⸻

⚠️ These projects are still concepts—not confirmed NASA missions. NASA’s NIAC program funds early-stage studies that explore technically ambitious ideas, helping researchers determine whether concepts like these could eventually become feasible missions.

⸻

The Moon’s far side could become one of the quietest places in the solar system for radio astronomy, potentially allowing scientists to study parts of the early Universe that Earth’s radio interference has kept hidden.

ON AUGUST 5, SOMETHING EXTRAORDINARY WILL HAPPEN ON THE MOON.

ON AUGUST 5, SOMETHING EXTRAORDINARY WILL HAPPEN ON THE MOON. A used Falcon 9 upper stage is expected to slam into the lunar surface near Einstein Crater after years drifting through space. Astronomers around the world are already preparing to observe the impact and the plume of material that could be blasted high above the Moon's surface. And this may become one of the most closely watched artificial impacts in lunar history. Think about that for a moment. A machine built by human hands, launched from Earth, traveling silently through the darkness of space, will end its journey by crashing into another world at thousands of kilometers per hour. The impact is expected to create a fresh crater and expose material hidden beneath the Moon's dusty surface. Scientists hope the collision could reveal layers that have remained untouched for millions of years, offering a rare opportunity to study what lies below. Even more fascinating, future lunar orbiters may be able to p...

Astronomers are Against The Startup's Idea to Sell Sunlight Using Gaint Mirrors in Space

Astronomers are Against The Startup's Idea to Sell Sunlight Using Gaint Mirrors in Space  Why Astronomers Are Up in Arms Over Space Startup’s Plan to Sell Sunlight The concept of manipulating planetary light from orbit sounds like something straight out of science fiction. For over a century, thinkers have toyed with the idea of positioning giant mirrors in space to redirect sunlight onto Earth after dark. Today, a California-based startup called Reflect Orbital is turning that theoretical concept into reality, pitching a service designed to "sell sunlight after dark". However, this ambitious technological push has triggered fierce opposition from the global scientific community. Astronomers, dark-sky advocates, and environmental researchers are sounding the alarm, warning that the project threatens to permanently alter the night sky, disrupt natural ecosystems, and deal a crippling blow to astronomical research.     What is Reflect Orbital Trying to Do? Found...

A Shared Horizon: Earth's Robotic Fleet Watching Over Mars When we look up at the Red Planet gleaming in our night sky, it's easy to see just a single, rusty dot. But right now, hidden away in the deep silence of space, Mars is surrounded by a bustling, international neighborhood. An incredible fleet of active orbiters from around the globe are working together—across borders and oceans—to unlock the deepest mysteries of our celestial neighbor. Here is a look at the incredible spacecraft keeping watch over Mars: United States (NASA)      2001 Mars Odyssey: The veteran of the fleet, serving as a steadfast workhorse and communication relay since it arrived.         Mars Reconnaissance Orbiter (MRO): Armed with a remarkably sharp eye, it maps Martian geology, monitors weather changes, and scouts landing sites.      MAVEN:A dedicated atmospheric detective studying how Mars lost its ancient, thick atmosphere and transformed into a desert.
