To practice shaping that reality, NASA sent DART hurtling toward its demise. “This is just the first step, but isn’t it exciting that we’re going from science fiction to science reality?”

“I don’t really lose sleep about the Earth getting destroyed by asteroids, but I am excited about living in a world where we might be able to potentially prevent this in the future,” says Nancy Chabot of Johns Hopkins University’s Applied Physics Laboratory (APL) in Laurel, Maryland, which manages the DART mission. And eventually, whether in hundreds or thousands or millions of years, it is all but certain that life on Earth will face an existential threat from an asteroid. While scientists are confident that a large enough asteroid to cause planet-wide extinction will not threaten Earth for at least a hundred years-after which time it is difficult to predict their orbits-it is still possible that we could be surprised by a smaller, potentially city-destroying rock from space. It's also the first test of a bold strategy that could be used to deflect any future asteroids that are on a collision course with Earth. ET, marks the first time humans have intentionally changed the course of a celestial object. The collision between NASA’s Double Asteroid Redirection Test (DART) spacecraft and a 500-foot-wide rock called Dimorphos, which took place at 7:14 p.m. The telescope will capture light that has been traveling for 10 billion years, allowing scientists to see 10 billion years into the past, the ESA said.Laurel, MarylandNearly seven million miles from Earth, a spacecraft traveling more than 14,000 miles an hour smashed into a small, unsuspecting asteroid that had been floating through space undisturbed for eons. In fact, though the speed of light can make livestreams difficult, in other cases, it has been a boon for scientific discovery. Most observations and data gathered by spacecrafts are beamed down to Earth a few hours or even days later - which isn't generally an issue for scientists. 'When it comes to a lengthy livestream from deep space, this is a first.' 'These missions were all pretty close to home and others farther away sent perhaps an image or two in near real-time,' the ESA said. There are only a few examples of 'live' footage in space, including the famous Apollo missions showing astronauts walk on the moon's surface, as well as the DART and LCROSS missions where NASA intentionally crashed spacecrafts into asteroids and the moon, respectively, the ESA said in a news release. What makes this unique, is that it's a one-hour livestream from Mars - but don't expect a detailed view of the #RedPlanet! /9BkL9elZRB- ESA Operations June 2, 2023 It's with this camera, originally meant for engineering purposes, that we'll get 'live' images this evening from 18:00 CEST in the first #MarsLIVE The livestream celebrates the 20th anniversary of the Mars Express mission, which launched in 2003 to better understand the planet, as well as search for traces of water. In 50-second intervals, the camera panned across Mars, showing a side of the planet entering night, as well as some clouds billowing out on the corner.

I'm excited to see Mars as it is now – as close to a martian 'now' as we can possibly get!' James Godfrey, the spacecraft operations manager at the ESA's mission control center, said in a statement. 'Normally, we see images from Mars and know that they were taken days before. Once light bounces off the planet, it can take between 3 to 22 minutes to travel to Earth - so there aren't truly 'live' images of Mars.īut on Friday afternoon, the European Space Agency offered the closest thing: the first 'livestream' of Mars on YouTube, which posted pictures of the planet every 50 seconds as they beamed down directly from the camera mounted on the agency's Mars Express orbiter.
