America is on the verge of a new era of space exploration, and America’s leadership in the space domain will be due to its courage to go and its conviction to stay. DOE, by many measures the “Department of Exploration,” is proud to be playing an essential part in rising to these challenges.
NASA and SpaceX recently launched American astronauts aboard an American rocket from American soil to the International Space Station for the first time since 2011, and America is actively planning to return to the Moon … and then go even further.
WASHINGTON (NASA PR) — NASA will host a special edition of NASA Science Live at 11 a.m. EDT, Wednesday, May 20, to share an exciting announcement about the agency’s Wide Field Infrared Survey Telescope (WFIRST) mission. The episode will air live on NASA’s website, NASA YouTube, NASA Facebook and Twitter/Periscope.
Members of the mission will respond to questions from the livestream chat in real time during the episode. Follow @NASA and @NASAWFIRST on Facebook and Twitter for additional information.
WFIRST is a space telescope that will conduct unprecedented large surveys of the infrared universe to explore everything from our solar system to the edge of the observable universe, including planets throughout our galaxy and the nature of dark energy.
WFIRST is managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, with participation by NASA’s Jet Propulsion Laboratory in Pasadena, California, the California Institute of Technology’s Infrared Processing and Analysis Center in Pasadena, the Space Telescope Science Institute in Baltimore, and a science team comprising scientists from research institutions across the United States.
A Direct Probe of Dark Energy Interactions with a Solar System Laboratory

We propose a mission concept for direct detection of dark energy interactions with normal matter in a Solar System laboratory. Dark energy is the leading proposal to answer the question of the accelerated expansion of the Universe. This interaction must be highly suppressed to be consistent with the gravity measurements and observations we have so far, but can be probed with specifically designed experiments.
By flying unscreened atomic particles through special gravitational field regions in the Solar System and conducting double differential measurements to isolate possible dark energy interaction with the atoms, we will stand a chance to achieve a direction detection of dark energy, akin to direct detection of dark matter and gravitational waves. This could lead to a fundamental shift in our understanding of fundamental physics and our universe, stimulating a wide variety of foundational research in cosmology and particle physics.
