Good afternoon. Today's PM is in holiday mode, with a short big thing and a quick recap of the news. Have a relaxing rest of your day.

1 big thing: NASA's mission accomplished

Three months after NASA sent the first spacecraft to Pluto, it has successfully flown by an object in the Kuiper Belt, man's next great frontier.

Why it matters: "Thirteen years and more than four billion miles [after launching a voyage to Pluto], New Horizons has provided humanity’s first glimpse of a distant fragment that could be unchanged from the solar system’s earliest days," the N.Y. Times notes.

The big picture: There are thought to be hundreds of thousands of objects like Ultima Thule in the Kuiper Belt.

  • The Kuiper Belt, where Ultima Thule is located, is a region of icy bodies beyond the orbit of Neptune that are thought to be leftovers from the solar system's early days, writes Axios Science editor Andrew Freedman.
  • The spacecraft will attempt to gather data on others to learn more about them, and how Ultima Thule might differ from them.

What's next: Expect to see more images and data from Ultima Thule later Tuesday and over the next 20 months. It takes about six hours for data to be transmitted one way back to Earth at 1,000 bits per second.

In subzero weather, Russian emergency workers pulled a year-old baby from the rubble of a collapsed apartment building today, the AP reports.

  • 11-month-old Ivan Fokin had been under rubble for nearly 36 hours.
  • "His father called it 'a New Year’s miracle.'"
  • Fokin was in "extremely serious condition, officials said, with fractures, a head injury and suffering from hypothermia."
