710-Boomer(496)

Travelers In The Night ·

2022/09/16

The fireball meteor streaking across the sky the early evening of January 17, 2018, witnessed by 700 observers in 11 States and Canada was also recorded by infrasonic microphones and seismometers. Scientific studies of this event gives researchers the ability to assess the risks presented by the 2,000 large fireball meteor explosions which occur each year world wide and will allow scientists to detect any secret nuclear tests being conducted by rogue individuals or governments.

709-Catching Asteroids(495)

Travelers In The Night ·

2022/09/09

Asteroid Mining Is Possible. It might be possible to catch an asteroid, place it into Earth orbit, and thus provide a ready source of precious metals and water for space colonists to use.

708-Guard Down(494)

Travelers In The Night ·

2022/09/02

In 2018, July and August were cloudy and rainy in both Arizona and Hawaii sidelining the worlds two most productive asteroid hunting surveys. A cost effective way to make the Earth's planetary defense system more weather proof is to put a network of asteroid hunting telescopes around the world to discover and track potentially dangerous nearby neighbors.

705-One Half Inch(491)

Travelers In The Night ·

2022/08/12

Fuzzy, spread out, asteroid images due to atmospheric and or equipment produced distortions can cause important objects to slip through an asteroid hunter's discovery images undetected. A careful monitoring of the temperature at a number of different locations in the observatory environment and using fans and other techniques to minimize temperature differences restores the power of a telescope so that it can detect possible asteroid threats to planet Earth.

Travelers In The Night ·

2022/08/05

There are likely to be hundreds smaller than softball sized and perhaps several dozen football to beachball sized, natural Earth mini moons, which are so small and fast moving that they are able to slip through asteroid hunters images without being detected.

702-20 years(488)

Travelers In The Night ·

2022/07/22

It has been 20 years since the world woke up to the news that a half mile diameter asteroid, 1997 XF11, discovered by Space Watch on Kitt Peak, had a slight chance of impacting the Earth in 2028. The NASA and JPL's Center for Near Earth Object Studies or CNEOS (see-neos) for short maps space rocks orbits, predicts when they will come close to us, and reliably determines each one's chance of impacting Earth.

Travelers In The Night ·

2022/07/15

Imagine a spacecraft traveling at a speed that would take it from New York to Tokyo in less than a minute, a mere 4 million miles from the surface of our Sun, where it would be exposed to about 500 times the solar radiation we receive here on Earth. Not science fiction but science fact for the NASA Parker Solar Probe on one of its final laps around our star.
