NASA’s psyche spacecraft, exploring the origins of the Solar System, returns to the track after the propellants lost energy
This explorer spacecraft is aimed at a strange asteroid with a naked metal core. I could have clues about how the earth started

The psyche of the robotic spacecraft has recovered the propulsion after an inconvenience cut in April. The engineers had to change to an support system, and the complete propeller operations resumed last week. The satellite is now scheduled to fly to Mars in May 2026, and then the traces in orbit around a very unusual asteroid (also called psyche) in August 2029. The problem of the propulsion had put this schedule, and in fact, while a a a a a a a a a a a a -Tanton, the main mission, the main mission, mission pressure and mission main Mission, mission and mission, blood pressure would have increased, “planetary scientist at Arizona State University.
Why does it matter
Approximately 4.5 billion years ago, our solar system was a cloud of gas and dust without planets. The stromeros used to think that the planets grew very slowly, over millions of millions of years, as gravity gradually grouped gas and dust. But the most recent evidence points to a much faster process that involves high energy collisions between dust, pebbles and rocks that crashed and then separated in a short time. Some of these clashes could have melted metals to form a nucleus (such as the one in the center of the earth) and surrounded it with a rocky crust. However, the nucleus of our planet has many hundred miles deep, to observe directly and precisely.

But the asteroid psyche, surrounding the sun between Mars and Jupiter, can have an exposed metal core. Radar’s reflections indicate that this is at least partial, says Jim Bell, a planetary scientist at Arizona State University, who is in charge of multispectral images of the psyche spacecraft. “If you were covered by rock, we would like the signal we are seeing,” he says. That signal indicates substances composed mainly of nickel and iron. Then, an asteroid overflight could provide the first -term first -term view of how the nucleus of a planet looks and answer questions about how it was formed.
What follows?
The problem with the Xenon gas propellants of the ship seemed to be caused by a defective valve, and when engineers changed to a second line of fuel, the ship recovered the movement. When psyche meets with your homonym of asteroids in 2029, the tube instruments should be able to detect any core discovered that the collisions have grown from rock. The orientation of the magnetic parts in that nucleus, like small compass needles, could indicate whether the asteroid ever had a magnetic dynamo, as the nucleus of the earth does. Notable, if there were impacts of the debris in the molten metal, they could have splashed and then freeze, leaving sharp cliffs so that the chambers of the spaceship show us.
More about psyche
The orbit Pysche asteroid in approximately three astronomical units, or Au, of the Sun (the orbit of the Earth is in an au). It is described as “potatoes”, with a diameter or 140 miles and a surface or 64,000 square miles.
