A chemist turned science writer, Victoria Corless completed her Ph.D. in organic synthesis at the University of Toronto and, ever the cliché, realized lab work was not something she wanted to do for the rest of her days.
Jam packed issues filled with the latest cutting-edge research, technology and theories delivered in an entertaining and visually stunning way, aiming to educate and inspire readers of all agesBelieve it or not, debris from Mars has frequently made its way to Earth after powerful impacts hit the Red Planet's surface and launch it into space.
Meteorites fall to Earth all the time — an estimated 48.5 tons of meteorite material falls each day,— though the majority make it to the surface as tiny unnoticeable particles of dust. Determining their origins can often be difficult, but in the 1980s, scientists became suspicious of a group of meteorites that appeared to have volcanic origins with ages of 1.3 billion years.
" enable the recalibration of Mars' chronology, with implications for the timing, duration and nature of a wide range of major events through Martian history," said Herd."I call that the missing link — to be able to say, for example, the conditions under which this meteorite was ejected were met by an impact event that produced craters between 10 and 30 kilometres across." The team combined high-resolution simulations of impacts into a Mars-like planet.

Debris from DART could hit Earth and Mars within a decade, say scientistsOn Sept. 26th, 2022, NASA's Double Asteroids Redirect Test (DART) collided with Dimorphos, the small moonlet orbiting the larger asteroid Didymos. In so doing, the mission successfully demonstrated a proposed strategy for deflecting potentially hazardous asteroids (PHAs)—the kinetic impact method.

Rocks from Mars' Jezero Crater, which likely predate life on Earth, contain signs of waterScientists report that rock samples from Mars' Jezero Crater contain minerals that are typically formed in water. While the presence of organic matter is inconclusive, the rocks could be scientists' best chance at finding remnants of ancient Martian life.
