Five scientists gathered at NASA's Kennedy Space Center on Tuesday to lay out the blueprints of an exhilarating space mission set to launch in just a couple of days. It's called Psyche.
NASA's Psyche probe will launch to a metal asteroid on Oct. 12 — and scientists are sneaking a peek at the target Upon ionization, those atoms gain a charge. The result? Ions. Then, those charged ions form an electric field which can, through a series of complicated steps, propel an object. In this case, that's the Psyche spacecraft.
Once the spacecraft reaches the vicinity of Mars, it will dip into the Red Planet's gravitational influence in order to be propelled like a slingshot toward Psyche itself. This is called a gravity assist, or as Oh puts it, a bit of"cosmic trickery." "Psyche today is long frozen, but if it formed as a metallic core in the early solar system, it was once a molten body and has been cooling really quickly and potentially generating a magnetic field." Weiss said."That magnetic field could be imprinted in the outer layers of Psyche's cold exterior as a kind of echo or fossil that we could then detect today." — and the gravity science experiment's scope actually also reaches into this stage.
DSOC, in a nutshell, uses lasers to exhibit a 10 times higher data transmission rate from Mars distances when compared to regular radio frequency transmitters."Future NASA missions, in particular those involving human exploration of Mars," Biswas said during the briefing,"demand much higher data return rates — and that's the motivation for this technology demonstration."
