4. Urban Astronomer – One of modern astronomy’s most enduring hoaxes comes around every year in August. Every year, we get asked by friends and family if it is true that Mars will appear as big as the Moon in the sky. This article from Urban Astronomer takes a closer look at what’s going on.
This series focuses on tangible evidence such as relics, artifacts, astronomical alignments and star maps that establishes the age of Astronomy.

Made in Space is the only organization ever in history to have the capability to manufacture off planet Earth.
The space industry has been bottlenecked for over 55 years due to the fact that everything we put in space has to launch on a rocket. By manufacturing in space, we can build objects that are far bigger than can fit into a rocket and unlock new mission opportunities. For instance, 100+ meter size antennas made in space can provide global broadband internet directly to personal devices. MIS has over $30mm in NASA, government, and commercial contracts bringing this vision to reality.
Their Mission: Industrial processing and manufacturing in space frees Earth from pollution and provides abundance as our technology needs advance.
A few days ago Centauri Dreams Paul Glister was at the Breakthrough Starshot meetings
Starshot engineering activities are targeting a 20% of lightspeed mission to Alpha Centauri. Kevin Parkin leads the subcommittee has oversight over a systems team that will conduct system engineering, modeling and integration activities.
Here is a follow up to the report of a SETI signal detected on May 15, 2015 by a radio telescope operated by the Russian Academy of Science. It appeared to come from the star HD 164595, a sun-like star located roughly 95 light-years from Earth. The system has only one known planet: a warm Neptune, so called because it is gaseous like Neptune but orbits its star in only 40 days. But the star probably has other planets — perhaps rocky ones.
If the signal was produced by intelligent aliens with a beacon transmitting radio waves in all directions, the energy it would need to produce 10^20 watts
If instead the beacon was targeted at Earth, then the power needed drops to 10^13 watts
Before astronomers jump to any conclusion, they’re attempting to detect the signal again. Last night, the SETI Institute used the Allen Telescope Array in northern California to track the star. They saw nothing, but will observe again tonight.
Some astronomers think that it could have been a earth produced military signal given the frequency range.
The amount of hydroxyl on the lunar surface is considerable, roughly 10 million tonnes at any instant, and much more over the Moon’s history. OH/H2O inside the Moon is also huge, estimated as 40 trillion to quadrillions of tonnes; with presumably only a small fraction ever reaching the PSRs (where about one billion tonnes reside). A reasonable estimate of water ever delivered to the lunar surface by comets and asteroids is 0.1–6 trillion tonnes, with perhaps 10–100 billion tonnes not lost to ionization on impact.
Moon Express plans to create a robotic lunar hydroxyl mining machine. It will fill a small fuel tank then it will launch into lunar orbit.
A second lunar robot lander will use the lunar orbit fuel to lower the cost.
Then there will two robotic lunar lander-miners
This will continue to four then eight lunar landers and a large lunar orbit fuel depot.
Then when the setup is large enough a lunar fuel depot will be towed to low earth orbit where it will be a low earth or other earth orbit fuel depot where it can sold to other companies and missions.
