NASA Tests Solid Rocket Motors for First Mars Rocket Launch NASA conducted successful tests of solid rocket motors in March and April 2023 at the Northrop Grumman facility in Elkton, Maryland, and Edwards Air Force Base in California. The motors will be used to launch the first rocket from the...
NASA's Asteroid Watch dashboard has identified five asteroids that will make relatively close approaches to Earth in the coming days. Largest Asteroid of 2023 HO6. Which is estimated to be about 880 feet wide. It will make its closest approach to Earth on July 5. Passing by at a distance...
The Earth's magnetic poles have reversed many times throughout its history. The last reversal was about 780,000 years ago. When the poles reverse, the north magnetic pole becomes the south magnetic pole, and vice versa. This reversal is caused by changes in the flow of liquid iron in the Earth's...
On this day in space, June 19, 1963, the Vostok 5 and Vostok 6 missions returned to Earth. Vostok 5 was piloted by Valery Bykovsky, while Vostok 6 was piloted by Valentina Tereshkova, the first woman in space. The two spacecraft flew in close proximity to each other for three...
The moon, Venus, Mars, and some of the brightest stars in the sky will be in a rare alignment this week, creating a celestial gathering that will be visible to skywatchers around the world. The moon will be in its waxing crescent phase, and it will appear to be just...
Introduction In the vast expanse of space, Earth's orbit is becoming increasingly cluttered with defunct satellites, spent rocket stages, and fragments from previous space missions. This accumulation of debris poses a growing threat to active satellites, space stations, and future space exploration endeavors. Enter Astro Scale, a pioneering company on...
Scientists have discovered two gigantic structures deep within the Earth that could be the remains of an ancient planet. The structures, which are each the size of a continent and 100 times taller than Mount Everest, were found in the Earth's mantle, the layer of rock that lies between the...
Introduction: SETI Project Looks for Technosignatures Humanity's age-old fascination with the possibility of life beyond Earth has fueled endeavors like the Search for Extraterrestrial Intelligence (SETI). The idea that we might one day receive a signal from an advanced extraterrestrial civilization is both tantalizing and scientifically profound. What Are Technosignatures?...
The birth and expansion of the universe is a complex topic that is still being studied by scientists. However, we do know a few things about how the universe began and how it has evolved over time. The Big Bang theory is the prevailing cosmological model for the universe. It...
Redshift and blueshift are two phenomena that describe how the frequency of light changes when an object is moving relative to an observer. When an object is moving away from an observer, the light from the object is redshifted, which means that the wavelength of the light increases and the...
