NASA's mission to the asteroid 16 Psyche has been moved forward by one year:

"We challenged the mission design team to explore if an earlier launch date could provide a more efficient trajectory to the asteroid Psyche, and they came through in a big way," said Jim Green, director of the Planetary Science Division at NASA Headquarters in Washington. "This will enable us to fulfill our science objectives sooner and at a reduced cost."

The Discovery program announcement of opportunity had directed teams to propose missions for launch in either 2021 or 2023. The Lucy mission was selected for the first launch opportunity in 2021, and Psyche was to follow in 2023. Shortly after selection in January, NASA gave the direction to the Psyche team to research earlier opportunities.

"The biggest advantage is the excellent trajectory, which gets us there about twice as fast and is more cost effective," said Principal Investigator Lindy Elkins-Tanton of Arizona State University in Tempe. "We are all extremely excited that NASA was able to accommodate this earlier launch date. The world will see this amazing metal world so much sooner."

The revised trajectory is more efficient, as it eliminates the need for an Earth gravity assist, which ultimately shortens the cruise time. In addition, the new trajectory stays farther from the sun, reducing the amount of heat protection needed for the spacecraft. The trajectory will still include a Mars gravity assist in 2023.

Now I'm psyched.

    The last fragment of a once-living planet,
    its body blasted into dust
    by the madness of its own inhabitants,
    while its head was cursed to roam aimlessly through time and space,
    screaming in pain and sorrow.
    In legend and in fact, it is known as:
    Metal Hurlant. [wikipedia.org]

    FWIW, Metal Hurlant Chronicles was rather unfairly ignored when it came out in 2014. If you overlooked it then, as I did, you should probably track down a copy online.
    While it's far from great, it's IMO definitely worth watching, if you like that sort of thing at all.
