Pasadena, CA – As the time when NASA will begin sending humans back to the Moon draws closer, crewed trips to Mars are an enticing next step. But future space explorers will need new tools when traveling to such distant destinations.
The Deep Space Atomic Clock mission is testing a new navigation technology that could be used by both human and robotic explorers making their way around the Red Planet and other deep space destinations.
In less than a year of operations, the mission has passed its primary goal to become one of the most stable clocks to ever fly in space; it is now at least 10 times more stable than atomic clocks flown on GPS satellites.
Pasadena, CA – This month marks 25 years since scientists first produced a fifth state of matter, which has extraordinary properties totally unlike solids, liquids, gases and plasmas. The achievement garnered a Nobel Prize and changed physics.
A new study in the journal Nature builds on that legacy. In July 2018, NASA’s Cold Atom Lab became the first facility to produce that fifth state of matter, called a Bose-Einstein condensate (BEC), in Earth orbit. A fundamental physics facility on the International Space Station, Cold Atom Lab cools atoms down to ultracold temperatures in order to study their basic physical properties in ways that would not be possible on Earth.
Pasadena, CA – NASA Astronaut Christina Koch recently gave a warm welcome to a very cool arrival to the International Space Station: a new piece of hardware for the Cold Atom Lab, an experimental physics facility that chills atoms to almost absolute zero, or minus 459 degrees Fahrenheit (minus 273 degrees Celsius). That’s colder than any known place in the universe.
The Cold Atom Lab has been up and running in the space station’s science module since July 2018 and is operated remotely from NASA’s Jet Propulsion Laboratory in Pasadena, California. Five groups of scientists on Earth are using the Cold Atom Lab to conduct a variety of experiments to help answer questions about how our world works at the smallest scales.
Pasadena, CA – On June 22nd, 2019, NASA will be sending a new technology to space that will change the way we navigate our spacecraft – even how we send astronauts to Mars and beyond.
Built by NASA’s Jet Propulsion Laboratory in Pasadena, California, the Deep Space Atomic Clock is a technology demonstration that will help spacecraft navigate autonomously through deep space. No larger than a toaster oven, the instrument will be tested in Earth orbit for one year, with the goal of being ready for future missions to other worlds.
Here are five key facts to know about NASA’s Deep Space Atomic Clock:
NASA’s Ames Research Center
Mountain View, CA – Astronauts live in a pretty extreme environment aboard the International Space Station. Orbiting about 250 miles above the Earth in the weightlessness of microgravity, they rely on commercial cargo missions about every two months to deliver new supplies and experiments.
And yet, this place is relatively protected in terms of space radiation. The Earth’s magnetic field shields space station crew from much of the radiation that can damage the DNA in our cells and lead to serious health problems.
NASA Jet Propulsion Laboratory
Pasadena, CA – NASA asks what’s the coldest place you can think of? Temperatures on a winter day in Antarctica dip as low as -120ºF (-85ºC). On the dark side of the Moon, they hit -280ºF (-173ºC). But inside NASA’s Cold Atom Laboratory on the International Space Station, scientists are creating something even colder.
The Cold Atom Lab (CAL) is the first facility in orbit to produce clouds of “ultracold” atoms, which can reach a fraction of a degree above absolute zero: -459ºF (-273ºC), the absolute coldest temperature that matter can reach.
NASA’s Jet Propulsion Laboratory
Pasadena, CA – NASA reports the International Space Station is officially home to the coolest experiment in space.
NASA’s Cold Atom Laboratory (CAL) was installed in the station’s U.S. science lab in late May and is now producing clouds of ultracold atoms known as Bose-Einstein condensates. These “BECs” reach temperatures just above absolute zero, the point at which atoms should theoretically stop moving entirely. This is the first time BECs have ever been produced in orbit.
CAL is a multiuser facility dedicated to the study of fundamental laws of nature using ultracold quantum gases in microgravity.

Greenbelt, MD – NASA’s Human Exploration and Operations and Science Mission Directorates are collaborating to make interplanetary internet a reality.
They’re about to demonstrate Delay/Disruption Tolerant Networking, or DTN – a technology that sends information much the same way as conventional internet does. Information is put into DTN bundles, which are sent through space and ground networks to its destination.
Washington, D.C. – NASA is focused on an ambitious plan to advance the nation’s space program by increasing science activities near and on the Moon and ultimately returning humans to the surface.
As part of the President’s fiscal year 2019 budget proposal, NASA is planning a new Moon-focused exploration campaign that starts with a series of progressive commercial robotic missions.
Washington, D.C. – NASA is providing an update on the first integrated launch of the Space Launch System (SLS) rocket and Orion spacecraft after completing a comprehensive review of the launch schedule.
