NASA is launching a box of lasers to make the coldest spot in the universe

With an experiment launching to the International Space Station Monday (May 21), scientists will be able to create a temperature that's 10 billion times colder than the vacuum of space to focus in on atoms' weird quantum behavior.

The Cold Atom Laboratory  (CAL) is a physics research facility the size of an ice chest, designed and built by NASA's Jet Propulsion Laboratory (JPL) in California, that will chill clouds of atoms with lasers and magnets aboard the space station to this ultracold temperature — close to absolute zero, or the lowest temperature possible.

Sunday's cargo launch to the space station, which is scheduled for 4:39 a.m. EDT (0839 GMT), will carry a number of experiments, including CAL.

Researchers will be able to conduct remote experiments in CAL, without any help from astronauts, for up to 6.5 hours every day, according to NASA's project page for CAL.

These ultracooled clouds of atoms are chilled to just about (but not quite) absolute zero. (Absolute zero is equivalent to minus 459.67 degrees Fahrenheit, or minus 273.15 degrees Celsius.) Known as Bose-Einstein condensates (BECs), the clouds contain atoms that are so cold, they move extremely slowly. Under Earth's gravity, the atoms in freely evolving BECs can't be slowed down enough for physicists to observe them for any longer than a fraction of a second, so scientists hardly get a chance to study their quantum characteristics, NASA officials said on the project page.

However, aboard the space station in a microgravity environment, things are much different. Without Earth's gravity getting in the way, these atoms can be slowed down more than they can anywhere else, using lasers and magnetic forces in an "ice-chest-like" compartment. The lasers slow down the atoms, cooling them to "like one-tenth of a billion of a degree above absolute zero," Robert Shotwell, CAL project manager and an engineer at JPL, said at a news conference on May 10.

In using CAL to study the atoms' quantum activity, physicists will be able to better understand how atoms behave at these extreme temperatures, a main thread in physics for over a century, according to a NASA overview.

After cooling the atoms, CAL will automatically load them into weak magnetic traps, where researchers can study them. With the atoms held in place, the teams will be able to observe them in a variety of quantum states and interactions, NASA officials said in the overview. At this extreme temperature, researchers can observe the quantum characteristics and behaviors of BECs for up to 10 seconds, according to the project page. This might not sound like a lot of time, but it's significant when compared to the observation time possible on Earth.

"Studying these hypercold atoms could reshape our understanding of matter and the fundamental nature of gravity," Robert Thompson, a CAL project scientist at JPL, said in a statement. "The experiments we'll do with the Cold Atom Lab will give us insight into gravity and dark energy — some of the most pervasive forces in the universe."

The CAL mission began development in 2012 and will operate through 2020.
