Space Mysteries: NASA’s OSIRIS-REx Reveals Some of Planet Earth’s Ancient Origins

The ultimate aim of space scientists is to discover the origins of life and then figure out how things may move in the future in a better, more predicatble, way. Easier said than done, but scientists across the globe are hard at work on it. In 2023, NASA's OSIRIS-REx spacecraft made a groundbreaking discovery on asteroid Bennu, shedding light on the building blocks of life on Earth. This remarkable finding adds to our understanding of how Earth became a life-sustaining planet.NASA's OSIRIS-REx mission unveiled evidence…

NASA hunts asteroid, makes amazing progress with Lucy Mission

NASA's Lucy mission has advanced further towards Asteroid Dinkinesh using precise maneuvers and now faces a communication blackout behind the Sun. Principal investigator Hal Levison leads the team's efforts, with mission management by NASA's Goddard Space Flight Center and spacecraft construction by Lockheed Martin Space.Over the past month, the Lucy Mission spacecraft team has observed that Asteroid Dinkinesh becoming brighter as the spacecraft approaches, along with a consistent brightness variation indicating a…

Volcanoes or Asteroid? AI Ends Debate Over Dinosaur Extinction Event

Dartmouth scientists used an innovative computer model to suggest that volcanic activity, rather than an asteroid impact, was the primary cause of the mass extinction that ended the age of the dinosaurs. This groundbreaking approach opens new avenues for investigating other geological events.Free-thinking computers reverse-engineered the fossil record to identify the causes of a cataclysm.To address the long-standing debate about whether a massive asteroid impact or volcanic activity caused the extinction of dinosaurs and…

From Saint John to outer space: These astronomy buffs have a new planetary namesake

Three New Brunswickers are enjoying an astronomical surprise: an asteroid has been named after them.It's called Mipach — using the first two letters from the names of Saint Johners Mike Powell, Paul Owen and Chris Curwin."I saw the email and the other two guys hadn't seen it yet. So I was frantically on the phone and messaging them back and forth, getting them to take a look. So it was just overwhelming," Curwin said.The asteroid is 6.37 kilometres in diameter and resides in the main belt, between the orbit of Mars and…

A lost asteroid could hit Earth next year, but the chances are small

A “lost asteroid” that hasn’t been seen since it was first discovered in 2007 has some scientists worried about the potential of an Earth-bound collision next year, reports indicate. The asteroid, which is known as 2007 FT3, was discovered by astronomers in 2007. However, the asteroid vanished within a day or so of the discovery.Since it vanished, NASA’s Center for Near Earth Object Studies (CNEOS) has tried to determine where the asteroid will travel, working to monitor it and the 32,000 other near-Earth…

If a Future Asteroid Threatens to Destroy Earth, Could We Stop It? : ScienceAlert

While preparing for the threat of an asteroid strike might seem like a hypothetical exercise, it's really not.The Solar System has calmed down a lot from earlier times when impacts were more frequent. But it is only a matter of time before an asteroid heads straight for Earth. The probability of an impact is not zero.Equally as difficult as determining when one will come for us is the task of getting humanity to cooperate and prepare for it.Here's an incontrovertible fact that thoughts and prayers can't brush aside: even…

Will ISRO ever conduct asteroid project like NASA’s Psyche mission? Know what its chief said

NASA on October 13, launched the Psyche mission from Launch Complex 39A, Kennedy Space Center in Florida. The asteroid mission took flight on a SpaceX Falcon Heavy rocket. The Psyche mission objectives include the study of the metal-rich asteroid named Psyche. It is an asteroid exploration project which aims to study Psyche asteroid's core, surface, relative ages of regions, and more. The mission has excited the scientific community and the public globally. So, will India ever undertake such an asteroid mission? Know…

Building-sized asteroid to fly past Earth TODAY! NASA reveals details of this upcoming close encounter

Studying asteroids can help scientists unlock the secrets of the Earth and how they formed. However, asteroids also pose a threat to the planet on occasion. These ancient space rocks have impacted Earth in the past and changed the course of history. More often than not, asteroids pass Earth at close but safe distances without ever touching the atmosphere even. However, it is still important to track them to minimize the uncertainties around their close approaches. NASA, the US space agency, has revealed that a…

NASA receives first-ever laser message on Earth from 16 mn km away! Know about DSOC experiment

NASA in October launched the Psyche mission to study a metal-rich asteroid orbiting the Sun between Mars and Jupiter. The Psyche spacecraft was installed with a Deep Space Optical Communications (DSOC) tool which made a mind-blowing achievement by sending the first-ever laser message to Earth from 16 million kilometres afar. The communication message was part of an experiment which NASA was able to conduct successfully. Know more about the DSOC experiment here.NASA DSOC experimentAccording to a NASA report, the DSOC…
