Space Laser: Testing an Interplanetary Internet from the Moon

Tonight, if you’re around the East Coast, you may be able to see a bright object quickly rising near the horizon about a half hour before midnight.

NASA's Lunar Atmosphere Dust Environment Explorer (or LADEE) mission is scheduled to launch from the Wallops Flight Facility on Virginia’s Eastern Shore at 11:27 pm EDT tonight. It should be visible (clouds permitting) up and down the East Coast, and as far inland as Pittsburgh.

LADEE is a robotic mission that—after taking about 30 days to make the trip—will enter orbit around the Moon to gather detailed information about the extremely thin lunar atmosphere, conditions near the surface, and environmental influences on lunar dust. A thorough understanding of these characteristics could help scientists understand other planetary bodies and inform any future exploration—human or robotic—of the Moon.

But there’s more to LADEE than just dust.

In President Obama’s historic 2010 Kennedy Space Center speech, as he challenged NASA to send humans into deep space for the first time, he also noted that this type of exploration would require investments in and development of breakthrough space technologies.

LADEE will be testing one of these breakthrough technologies—specifically, a new kind of laser communications. One of the big problems with any space mission is getting data back to Earth. Right now, all of those cool pictures from our Mars rovers are only able to come back to Earth very slowly—think of the early days of dial-up Internet.  Just one image from the Mars Reconnaissance Orbiter takes about 1.5 hours to transmit back to Earth. LADEE includes the first test of laser communications that can potentially lead to higher data rates from deep space, which could mean broadband speeds from the Moon. Some might call this the first step of an Interplanetary Internet.

Future and more complex missions will require significantly higher data rates than existing communications allow, enabling entirely new missions of scientific discovery using next generation instruments and high-data-rate communications for exploration. The technology demonstrated by optical communications on LADEE is directly applicable to the next generation of NASA's space communications network. This is why NASA’s newly created Space Technology Mission Directorate is pursuing the Laser Communications Relay Demonstration—the next step in developing space communications systems of the future. The demonstration will use lasers to encode and transmit data at rates 10- to 100-times faster than radio.

Optical laser communications will enable a variety of robust future science and human exploration missions—providing a higher data rate, and delivering more accurate navigation capabilities with reduced size, weight, and power requirements.  Someday, maybe, the Solar System will be peppered with a high-speed interplanetary communications network much like the wireless Web currently spinning here on Earth.

Tonight’s scheduled launch will be carried live on NASA TV. You can also track mission status by following @NASALADEE or at the mission website.

White House and Hill Reps Single-minded on the Value of Neuroscience

This summer I joined with Congressman Chaka Fattah (D-PA) and more than 40 scientists, advocates, and business leaders at Philadelphia’s University City Science Center to discuss recent advances in neuroscience research. The meeting gave OSTP and the Congressman an opportunity to brief some of the Nation’s top brain researchers and thought leaders on Federal investments and initiatives in neuroscience and related areas, and the importance of public-private partnerships in advancing neuroscience exploration.

The Obama Administration is committed to harnessing science to understand the underpinnings of brain diseases, improve the diagnosis and treatment of traumatic injuries to the brain, and apply the latest discoveries about the neuroscience of teaching, learning, and development in educational settings across the country. In April, for example, the President announced the launch of the Brain Research Through Advancing Innovative Neurotechnologies (BRAIN) Initiative, which is focusing in part on developing better technologies and tools to accelerate progress in this important domain.

The Administration has had a longstanding interest in neuroscience. At the Philadelphia meeting, I provided an overview of a series of related initiatives and activities in areas such as neurodegenerative disease, mental health, behavioral science, and neuroethics. Such efforts would be difficult indeed without the strong support of leaders like Rep. Fattah, who worked closely with OSTP in 2011 to establish the Interagency Working Group on Neuroscience, which coordinates research among more than a dozen agencies under the National Science and Technology Council.
