2021/09/28

Juno was found by German astronomer Karl L. Harding in 1804 who noticed that to the human eye it appeared to be a star like moving point of light in the night sky. The light that Juno reflects suggests that it could be the source of stony meteorites called chondrites that we find on Earth.

659-Martian Debris(382)

Travelers In The Night ·

2021/09/24

Martian Trojan asteroids have stable orbits around the Sun, leading and trailing the red planet by 60 degrees, where the Sun's and Mars's gravity are balanced. The impact more than 4 billion years or so ago which blasted loose the Trojan asteroids and gave them the 3mi/s required to escape the red planet gives us an insight into the level of violence which occurred before our solar system came into it's present relatively calm state.

2021/09/21

Recently my NASA funded Catalina Sky Survey teammate Carson Fuls discovered an approaching asteroid about the same size as the one whose high altitude disintegration injured nearly 1500 people in Chelyabinsk Russia in February of 2013. Fortunately this new one missed planet Earth. There is more good news. Carson spotted this small space rock about 40 hours before its closest approach to planet Earth. This means that if it had been on a collision path with our home planet we would have had time

Travelers In The Night ·

2021/09/10

On Earth, human life is enabled by plants which provide us with calories, vitamins, fuel, medicines, and oxygen to breathe. In addition, recent scientific studies indicate that plant cultivation reduces anxiety and depression and has a positive influence on diabetes, heart disease, obesity, and longevity. It is likely that when humans travel to Mars they will continue this practice. The plants that Mars explorers take with them will provide a source of fresh fruits and vegetables , fresh air to

141E-153-Alien Invaders

Travelers In The Night ·

2021/08/10

The most likely alien invaders are viruses or other bits of living materials that humans have exported from or imported to Earth's biosphere. Currently there are international efforts, like the outer space treaty and the Committee on Space Research, to keep the human exploration of space from spreading Earth's life forms to other places or to contaminate our own biosphere with extraterrestrial organisms if they exist.

My Catalina Sky Survey teammate Greg Leonard discovered, 2016 WJ1, a relatively large asteroid which can come close but will not hit the Earth. Once in every million years or so an asteroid impact by an object of this size could cause global climate change disrupting human agriculture and plunge our society into a real crisis.
