"Professor Goddard does not know the relation between action and reaction and the need to have something better than a vacuum against which to react. He seems to lack the basic knowledge ladled out daily in high schools."
--1921 New York Times editorial about Robert Goddard's revolutionary rocket work.

"Correction: It is now definitely established that a rocket can function in a vacuum. The 'Times' regrets the error."
NY Times, July 1969.

Solar Powered Moon Brick Factory Could Build Future Lunar Cities

Universe Today - Sun, 08/10/2025 - 5:17am

Imagine building an entire city on the Moon using nothing but sunlight and lunar soil! Chinese scientists have made this science fiction dream a reality by creating a revolutionary machine that acts like a solar powered 3D printer, melting lunar soil at temperatures exceeding 1,300°C to create strong construction bricks. This technology could transform space exploration by eliminating the need to transport heavy building materials from Earth, making lunar bases not only possible but affordable.

What Cosmic Dust Can Reveal About Earth's Early Atmosphere

Universe Today - Sat, 08/09/2025 - 7:30am

Earth has endured, and been shaped by, a constant rain of material from elsewhere in the Solar System. Some of the material was large, like the Chicxulub asteroid that ended the dinosaur's reign. But most of it is in the form of tiny micrometeorites. Those tiny rocks hold clues to Earth's ancient atmosphere.

Six Of Ingenuity's Successors Could Be Exploring Mars In 4 Years

Universe Today - Sat, 08/09/2025 - 7:30am

Ingenuity marked a number of milestones in space exploration. Arguably most importantly, it proved that powered flight was possible on another planet. However, it did have some limitations, such as being tied to the Perseverance rover and there only being one copy of the helicopter itself. AV Inc, one of the sub-contractors for Ingenuity, hopes to fix those problems with a proposed new mission called Skyfall that would involve six helicopters and no rover.
