FULL STORY (With Graphics):NASA funds proposal to build a telescope on the far side of the moon
NASA is funding an early-stage proposal to build a meshed telescope inside a crater on the far side of the moon ...
This "dark side" is the face of the moon that is permanently positioned away from Earth, and as such it offers a rare view of the dark cosmos, unhindered by radio interference from humans and our by our planet's thick atmosphere.
The ultra-long-wavelength radio telescope, would be called the "Lunar Crater Radio Telescope" and would have "tremendous" advantages compared to telescopes on our planet, the idea's founder Saptarshi Bandyopadhyay, a robotics technologist at NASA's Jet Propulsion Laboratory wrote in a proposal. ...
NASA's Innovative Advanced Concepts Program is awarding $125,000 for a Phase 1 study to understand the feasibility of such a telescope, Bandyopadhyay told Vice.

The Solar System has been here for a long time. So, when 'Oumuamua was spotted in 2017, it was almost a dead cert it wasn't the only object from interstellar space to visit us over that 4.57 billion-year history. Then comet 2I/Borisov showed up last year. That basically clinched it.
But where are the rest of our interstellar visitors? We'll probably find a few more flying in from the wilds in the coming years. And, according to new research, a whole bunch of interstellar asteroids have been hanging out right here in the Solar System for a very long time.
Based on how they move around the Sun, a team of researchers has identified 19 asteroids they think were captured from another star, way back when the Solar System was just a few million years old. ...
Live video:The instantaneous launch window opens at 4:33 p.m. EDT, or 20:33 UTC, with backup instantaneous launch opportunities available on Saturday, May 30 at 3:22 p.m. EDT, or 19:22 UTC, and on Sunday, May 31 at 3:00 p.m. EDT, or 19:00 UTC. Tune in here to watch the launch webcast. Coverage will begin about 4 hours before liftoff.
After standing down from launch on Wednesday May 27, SpaceX is now targeting Saturday, May 30 for Falcon 9’s launch of Crew Dragon’s second demonstration (Demo-2) mission from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida. This test flight with NASA astronauts Bob Behnken and Doug Hurley on board the Dragon spacecraft will return human spaceflight to the United States.
The instantaneous launch window opens at 3:22 p.m. EDT, or 19:22 UTC, with a backup instantaneous launch opportunity available on Sunday, May 31 at 3:00 p.m. EDT, or 19:00 UTC. Tune in here to watch the launch webcast. Coverage will begin about 4 hours before liftoff.
Demo-2 is the final major test for SpaceX’s human spaceflight system to be certified by NASA for operational crew missions to and from the International Space Station. SpaceX is returning human spaceflight to the United States with one of the safest, most advanced systems ever built, and NASA’s Commercial Crew Program is a turning point for America’s future in space exploration that lays the groundwork for future missions to the Moon, Mars, and beyond.

When you picture the Solar System in your head, most people would think of the Sun, stolid and stationary in the centre, with everything else whizzing about around it. But every body in the Solar System also exerts its own gravitational tug on the star, causing it to move around just a tiny bit.
Therefore, the precise gravitational centre (or barycentre) of the Solar System is not smack-bang in the middle of the Sun, but somewhere closer to its surface, just outside it. But it hasn't been easy for us to figure out exactly where this barycentre is, due to the myriad gravitational influences at play. ...
