Nasa launches Psyche mission to study an ancient metal asteroid
Nasa launches Psyche mission to study an ancient metal asteroid
Nasa has launched its Psyche craft into space, on a mission to study an ancient, metallic asteroid. The spacecraft set off on a six year journey, carried away by one of SpaceX’s Falcon Heavy rockets. It is aimed at an asteroid, also called Psyche, where it will arrive in 2029 and hopes to look back to the beginnings of our own Earth. Most asteroids tend to be rocky or icy, and this is the first exploration of a metal world. Scientists believe it may be the battered remains of an early planet’s core, and could shed light on the inaccessible centers of Earth and other rocky planets. SpaceX launched the spacecraft into a midmorning sky from NASA’s Kennedy Space Center. Psyche should reach the huge, potato-shaped object in 2029. After decades of visiting faraway worlds of rock, ice and gas, NASA is psyched to pursue one coated in metal. Of the nine or so metal-rich asteroids discovered so far, Psyche is the biggest, orbiting the sun in the outer portion of the main asteroid belt between Mars and Jupiter alongside millions of other space rocks. It was discovered in 1852 and named after Greek mythology’s captivating goddess of the soul. “It’s long been humans’ dream to go to the metal core of our Earth. I mean, ask Jules Verne,” said lead scientist Lindy Elkins-Tanton of Arizona State University. “The pressure is too high. The temperature is too high. The technology is impossible,” she added. “But there’s one way in our solar system that we can look at a metal core and that is by going to this asteroid.” Astronomers know from radar and other observations that the asteroid is big — about 144 miles (232 kilometers) across at its widest and 173 miles (280 kilometers) long. They believe it’s brimming with iron, nickel and other metals, and quite possibly silicates, with a dull, predominantly gray surface likely covered with fine metal grains from cosmic impacts. Otherwise, it’s a speck of light in the night sky, full of mystery until the spacecraft reaches it after traveling more than 2 billion miles (3.6 billion kilometers).Scientists envision spiky metal craters, huge metal cliffs and metal-encrusted eroded lava flows greenish-yellow from sulfur — “almost certain to be completely wrong,” according to Elkins-Tanton. It’s also possible that trace amounts of gold, silver, platinum or iridium — iron-loving elements — could be dissolved in the asteroid’s iron and nickel, she said. “There’s a very good chance that it’s going to be outside of our imaginings, and that is my fondest hope,” she said. Believed to be a planetary building block from the solar system’s formation 4.5 billion years ago, the asteroid can help answer such fundamental questions as how did life arise on Earth and what makes our planet habitable, according to Elkins-Tanton.On Earth, the planet’s iron core is responsible for the magnetic field that shields our atmosphere and enables life. Led by Arizona State University on NASA’s behalf, the $1.2 billion mission will use a roundabout route to get to the asteroid. The van-size spacecraft with solar panels big enough to fill a tennis court will swoop past Mars for a gravity boost in 2026. Three years later, it will reach the asteroid and attempt to go into orbit around it, circling as high as 440 miles (700 kilometers) and as close as 47 miles (75 kilometers) until at least 2031. The spacecraft relies on solar electric propulsion, using xenon gas-fed thrusters and their gentle blue-glowing pulses. An experimental communication system is also along for the ride, using lasers instead of radio waves in an attempt to expand the flow of data from deep space to Earth. NASA expects the test to yield more than 10 times the amount of data, enough to transmit videos from the moon or Mars one day. The spacecraft should have soared a year ago, but was held up by delays in flight software testing attributed to poor management and other issues. The revised schedule added extra travel time. So instead of arriving at the asteroid in 2026 as originally planned, the spacecraft won’t get there until 2029. That’s the same year that another NASA spacecraft — the one that just returned asteroid samples to the Utah desert — will arrive at a different space rock as it buzzes Earth.

Nasa’s Psyche mission set to launch to ancient metal asteroid today: Live updates
Nasa’s Psyche mission set to launch to ancient metal asteroid today: Live updates
Nasa is about to set off to a distant, metal asteroid that could tell us how planets form. On Friday, the spacecraft – currently folded in the cargo bay of a SpaceX rocket – will leave from the Kennedy Space Centre and begin a mission that will see it arrive at what is thought to be an ancient remnant of a protoplanet in 2029. Propelled by a system of solar-electric ion thrusters being used for the first time on an interplanetary mission, the spacecraft - about the size of a small van - is expected to reach its target on the outer fringes of the main asteroid belt between Mars and Jupiter nearly six years from now. It would then orbit Psyche for 26 months, scanning the asteroid with instruments built to measure the asteroid’s gravity, magnetic proprieties and composition. Psyche measures roughly 173 miles (279 km) across at its widest point. The leading hypothesis for this asteroid’s origin is that Psyche is the once-molten, long-frozen inner hulk of a baby planet torn apart by collisions with other celestial bodies at the dawn of the solar system. It orbits the sun about three times farther than Earth, even at its closest to our planet.
