  • May 14, 2015: First Laboratory Demonstration of Photonic Laser Thruster to propel simulated spacecraft. Y.K. Bae Corporation announces their proprietary Photonic Laser Thruster (PLT) has successfully accelerated a 450 gram (~1 lb.) spacecraft simulator with pure laser light for the first time in history. The project was funded by a Phase II grant of NASA Innovative Advanced Concepts (NIAC), which funds the most promising ideas for the next generation NASA space missions.


  • September 24, 2014: NIAC/NASA announced to continue the Photonic Laser Thruster program into Year II. Last year, NASA awarded Y.K. Bae Corp. an Innovative Advance Concepts (NIAC) Phase II grant to investigate innovative spacecraft maneuvering and formation flying with Photonic Laser Thrusters (PLT). The grant is one of six visionary technology grants for continued study under the NIAC program. According to NASA, NASA's Space Technology Mission Directorate awarded the PLT grant for its potential to transform future aerospace missions, introduce new capabilities, or significantly improve current approaches to building and operating aerospace systems.


  • September 23, 2014: The article, "Metastable Innershell Molecular State (MIMS) II: K-shell x-ray satellites in heavy impacts on solids," has been accepted for publication in Results in Physics. In this paper, the MIMS model has been extended and applied to interpreting the experimental K-shell x-ray satellite spectra for more than 40 years in keV-MeV/amu heavy-ion impact on solids. The binding energies of the K-shell MIMS of elements from Al to Ti were determined to be 80 - 200 eV. The successful extension of the model to the K-shell MIMS confirms that all elements in the periodic table and their combinations are subjected to the MIMS formation.


  • September 10, 2014: The article, "Metastable Innershell Molecular State (MIMS) III: The universal binding energy and bond length of the homonucleus K-shell MIMS," has been accepted for publication in Physics Letters A. The article reports the discovery of a universal Z2-dependency of the binding energy of the homonucleus K-shell MIMS (Metastable Innershell Molecular State bound by K-shell electrons), which has been established by analyzing extensive existing experimental data over several decades. The successful extension of the MIMS model to a wide range of K-MIMS phenomena, and the discovery of the universal Z-dependent behavior of the K-MIMS confirm that all elements and their combinations in the periodic table are subjected to the MIMS formation.


  • August 1, 2014: DTRA (Defense Threat Reduction Agency) selected Y.K. Bae Corp. for an SBIR Phase II award to investigate commercial potential of super-intense x-ray generation with MIMS (Metastable Innershell Molecular State) in the areas from semiconductor lithography to x-ray laser in collaboration with Los Alamos National Lab. MIMS was originally discovered by Dr. Bae and his colleagues at the Brookhaven National Lab in 1993. MIMS is a high-energy transient molecular quantum state formed by innershell electrons during extremely high-pressure (>100 million atmospheric pressure, or 10 Tera-Pascal) compression of matter to form High Energy Density Materials (HEDM) and Warm Dense Matter (WDM), that are predicted to be found in large planets and stars, and near black holes.


  • February 6, 2014: Dr. Bae will give an oral presentation in 2014 NIAC Symposium that will be held at Stanford University in Palo Alto, CA on February 4-6, 2014. The 2014 NIAC Symposium will feature progress presentations from NIAC Fellows and exciting keynote addresses. The keynote speakers include: Jamie Hyneman (MythBusters Host), Peter Norvig (Director of Research at Google), and Seth Shostak (Senior Astronomer at SETI). The Symposium is open to the public.


  • January 9, 2014: Dr. Bae will give an invited talk in the Pure Photon Propulsion session of 2014 High Power Laser Ablation and Beamed Energy Propulsion Conference in Santa Fe, New Mexico on April 25th 2014. The title of the talk is: Past, Present and Future of Photon Propulsion.


  • November 18, 2013: The Space Show interviewed Dr. Bae on Photonic Laser Thrusters and Photonic Railways.


  • October 22, 2013: The article, "Creating Nanostars with Buckyballs," has been accepted for publication in Physics Letters A. The article reports our recent work on creating superradiant quantum nanoplasmas (Nanostars) by impacting buckyballs (C60) at hypervelocities (v>100km/s) in an innovative tabletop apparatus. The nanostars are estimated to have ~10 TPa (100 Mbar, 100 million times of atmospheric pressure) transient pressures and convert ~35 % of impact energy into soft-x-ray energy. The ultrahigh-efficiency conversion is proposed to result from Dicke Superradiance of Metastable Innershell Molecular State (MIMS), originally discovered by Dr. Bae and his colleagues in 1994. The usage of buckyballs and successful orders-of-magnitude scaling down of the apparatus size and complexity establish an innovative tabletop method for generation, study, and widespread utilization of matter in planetary or stellar interiors and potentially open doors to numerous unprecedented applications.


  • October 15, 2013: Popular Science featured an article regarding Metastable Innershell Molecular State (MIMS) entitled, "Tabletop Device Would Destroy Chemical Weapons with X-Rays." MIMS was originally discovered by Dr. Bae and his colleagues at the Brookhaven National Lab in 1993. MIMS is a high-energy transient molecular quantum state formed by innershell electrons during extremely high-pressure (>100 million atmospheric pressure, or 10 Tera-Pascal) compression of matter to form High Energy Density Materials (HEDM) and Warm Dense Matter (WDM), that can be found inner cores of large planets, such as Jupiter or Saturn.


  • October 9, 2013: Popular Mechanics featured an article regarding Photonic Laser Thruster entitled, "Cosmic Concept: Laser Powered Space Travel." Propellantless thrust beaming via recirculating photons between space vehicles by Photonic Laser Thruster (PLT) technology was first developed and patented by Dr. Bae in 2007. Since then, space researchers have come to view PLT as particularly appropriate for cost-effective multi-vehicle, or formation flying applications. Recently, a NASA NIAC Phase II grant was awarded to investigate these applications and the PLT flight demonstration in space. Where today's state-of-the-art spacecraft technology involves maneuvering by more costly, limited life-cycle, onboard ion thrusters, PLT uses non-contacting inter-body thrust exchange to enable unprecedented propellantless spacecraft maneuvers and to achieve and maintain precise vehicle positioning in space. Traditional "all-in-one" single-vehicle architecture requires that mission-critical, expensive components accompany consumable components, such as fuel and main power supplies. With PLT it is conceivable that a highly valuable mission vehicle can be separated from a lower-cost, replaceable resource vehicle to exponentially lower life-cycle costs while extending missions in space indefinitely. This Popular Mechanics article focuses on potential far-term usage of PLT for interstellar travel.

  • June 7, 2013: Dr. Bae will give an oral presentation and a poster presentation with Los Alamos National Lab on "Creating Nanostars with Buckyballs (C60)" at APS-SCCM Conference on July 8th and 9th. Nanostars have been created and studied at Y. K. Bae Corp. by impacting buckyballs (C60) at hypervelocities (v>100km/s) in an innovative tabletop apparatus under the auspice of DTRA.  The Nanostars are estimated to have ~10 TPa (100 million atmosphere pressure) transient pressures and convert ~35 % of impact kinetic energy into soft-x-ray energy.   The ultrahigh-efficiency conversion is proposed to result from Dicke Superradiance of Metastable Innershell Molecular State (MIMS), originally discovered by Dr. Bae and his colleagues in 1994 at Brookhaven National Lab with the use of a large particle accelerator.  The innovative usage of buckyballs and successful orders-of-magnitude scaling down of the apparatus size and complexity establish an innovative tabletop method of generating and studying matters in planetary or stellar interiors and open doors to numerous unprecedented applications.

The Photonic Railway combines two essential technologies: 1) Photonic Laser Thruster (PLT) and 2) Beamed Laser Propulsion (BLP) by Dr. Forward. The proposed development of interstellar commutes starts with near-earth activities using Photonic Laser Thrusters (PLT), and expands to interlunar and interplanetary photonic railways that are proposed to be stepping stones for the realizing final interstellar Photonic Railway.
