Warp Drive Research at NASA JSC

"This paper will begin with a short review of the Alcubierre warp drive metric and describes how the phenomenon might work based on the original paper. The canonical form of the metric was developed and published in [6] which provided key insight into the field potential and boost for the field which remedied a critical paradox in the original Alcubierre concept of operations. A modified concept of operations based on the canonical form of the metric that remedies the paradox is presented and discussed. The idea of a warp drive in higher dimensional space-time (manifold) will then be briefly considered by comparing the null-like geodesics of the Alcubierre metric to the Chung-Freese metric to illustrate the mathematical role of hyperspace coordinates. The net effect of using a warp drive "technology" coupled with conventional propulsion systems on an exploration mission will be discussed using the nomenclature of early mission planning. Finally, an overview of the warp field interferometer test bed being implemented in the Advanced Propulsion Physics Laboratory: Eagleworks (APPL:E) at the Johnson Space Center will be detailed. While warp field mechanics has not had a "Chicago Pile" moment, the tools necessary to detect a modest instance of the phenomenon are near at hand." More

Opportunity Reveals Geological Mystery

NASA's long-lived rover Opportunity has returned an image of the Martian surface that is puzzling researchers.

"NASA is announcing opportunities for academia, industry and government agencies to develop and carry out research and technology demonstrations on the International Space Station using the newly installed Space Communications and Navigation (SCAN) testbed. There are two announcements of opportunity. The SCAN Testbed Experiment Opportunity invites industry and other government agencies to enter into Space Act Agreements with NASA to use the space station's SCAN platform. The SCAN Testbed Cooperative Agreement Notice invites academia to develop proposals to use the orbiting laboratory's SCAN testbed research capabilities. NASA expects the first demonstrations by late 2013 or early 2014. These opportunities will allow researchers to develop new software according to the Space Telecommunications Radio Standard (STRS) architecture for radios and reconfigure how radios communicate in space."

"NASA has selected eight advanced robotics projects that will enable the agency's future missions while supporting the Obama administration's National Robotics Initiative. The projects, ranging from technologies for improving robotic planetary rovers to humanoid robotic systems, will support the development and use of robots for space exploration, as well as by manufacturers and businesses in the United States. Robots can work beside, or cooperatively, with people to enhance individual human capabilities, performance and safety in space as well as here on Earth. Co-robotics, where robots work cooperatively with people to enhance their individual human capabilities, performance and safety, is a valuable tool for maintaining American leadership in aerospace technology and advanced manufacturing. "Robonaut, NASA's robotic crewmember aboard the International Space Station, is being tested to perform tasks to assist our astronauts and free them up to do the important scientific research and complex engineering taking place each day on our orbiting national lab," said NASA Chief Technologist Mason Peck at NASA Headquarters in Washington. "Selected through our participation in the National Robotics Initiative, these new projects will support NASA as we plan for our asteroid mission in 2025 and the human exploration of Mars around 2035."

Dry Ice Snowfall on Mars

NASA's Mars Reconnaissance Orbiter (MRO) data have given scientists the clearest evidence yet of carbon dioxide snowfalls on Mars. This reveals the only known example of carbon dioxide snow falling anywhere in our solar system.

Mighty Eagle Aces Major Exam

Completing this round of flight test objectives, the "Mighty Eagle," a NASA robotic prototype lander, flew to an altitude of 100 feet and descended gently to a controlled landing during a successful free flight Sept. 5 at NASA's Marshall Space Flight Center in Huntsville, Ala.

Curiosity Begins Arm-Work Phase

After driving more than a football field's length since landing, NASA's Mars rover Curiosity is spending several days preparing for full use of the tools on its arm.

Tracks from the first drives of NASA's Curiosity rover are visible in this image captured by the High-Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. The rover is seen where the tracks end. The image's color has been enhanced to show the surface details better.

Tracking Objects in Space

To continue successfully keeping track of objects in orbit around Earth, the U.S. Air Force should become more open and transparent in the creation and dissemination of its algorithms, processes, and research in astrodynamics, according to a new report from the National Research Council.

Name an Asteroid

"Students worldwide have an opportunity to name an asteroid from which an upcoming NASA mission will return the first samples to Earth. Scheduled to launch in 2016, the mission is called the Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer (OSIRIS-REx). Samples returned from the primitive surface of the near-Earth asteroid currently called (101955) 1999 RQ36 could hold clues to the origin of the solar system and organic molecules that may have seeded life on Earth. NASA also is planning a crewed mission to an asteroid by 2025. A closer scientific study of asteroids will provide context and help inform this mission. The competition is open to students under age 18 from anywhere in the world. Each contestant can submit one name, up to 16 characters long. Entries must include a short explanation and rationale for the name. Submissions must be made by an adult on behalf of the student. The contest deadline is Sunday, Dec. 2, 2012." More

Dune Migration on Mars

This image shows large sand dunes in the North Polar sand sea on Mars. It is one of a series of repeat images of the same dunes, taken at different times, in order to determine the type and extent of changes in the dunes over time.

Water Ice in Shackleton Crater's Walls

Scientists using the Mini-RF radar on NASA's Lunar Reconnaissance Orbiter (LRO) have estimated the maximum amount of ice likely to be found inside a permanently shadowed lunar crater located near the moon's South Pole.

Saturn and Titan

Posing for portraits for NASA's Cassini spacecraft, Saturn and its largest moon, Titan, show spectacular colors in a quartet of images being released today. One image captures the changing hues of Saturn's northern and southern hemispheres as they pass from one season to the next.

Curiosity Begins Eastbound Trek

NASA's Mars rover Curiosity has set off from its landing vicinity on a trek to a science destination about a quarter-mile (400 meters) away, where it may begin using its drill.

NASA's Wide-field Infrared Survey Explorer (WISE) mission has led to a bonanza of newfound supermassive black holes and extreme galaxies called hot DOGs, or dust-obscured galaxies.

NASA's Kepler mission has discovered multiple transiting planets orbiting two suns for the first time. The system, known as a circumbinary planetary system, is 4,900 light-years from Earth in the constellation Cygnus.
