astronomyPerformance simulation of a next generation space based gravity detector starting in 2034

No Comments
The next-generation gravity observatory, called LISA, is expected to be in space in 2034, and it will be sensitive to gravitational waves of a lower frequency than those detected by the Earth-bound Laser Interferometer Gravitational-Wave Observatory (LIGO). A new Northwestern …

chinaChina launching relay satellite to Lagrange 2 to support rover probe to far side of moon

No Comments
China plans to launch a relay satellite into space next Monday, May 21, for the Chang’e-4 lunar probe scheduled later this year. The Chang’e-4 lunar probe will undertake the first ever soft landing on the far side of the Moon. …

astronomyRobert Zubrin says we can find alien life with planets with free oxygen

No Comments
Robert Zubrin says it takes life to create an atmosphere with free oxygen. If we analyze the spectrum of atmosphere for exoplanets and find free oxygen he argues we will have found alien life. If we find a region of …

physicsSolar Sails and Electric sails

No Comments
With composite booms, the NASA principal investigator believes we could make 1000 to 4000 square meter solar sails today with a funded project. Then with the learnings from that mission we could rapidly advance to 10,000 square meter solar sails. …

lasersBeam propulsion background and Breakthrough starshot update

No Comments
Beamed propulsion could achieve single stage to orbit. It could be 6 to 100 times cheaper. Most of the rocket becomes payload. DARPA funded developing a heat exchanger for direct energy. They tested a microwave beam director for a 100KW …

magneticRobert Zubrin has new propellentless space propulsion concept – Dipole Drive

No Comments
Robert Zubrin was an inventor of the magnetic sail with Dana Andrews when they looked at the drag of a magnetic scoop intended for a Bussard ramjet. The magnetic sail would be great for a lighter braking mechanism for interstellar …

physicsPositron Dynamics Antimatter propulsion drive update April 2018

No Comments
Positron Dynamics gave an overview and update on their Antimatter propulsion work. They are slowing the positrons that are generated. Krypton isotopes to generate hot positrons. Use their system to moderate the positrons so they can be used. They need …

emdriveThe SpaceDrive Project – First Results on EMDrive and Mach-Effect Thrusters

No Comments
Tajmar is finding more magnetic interaction from cables. He is not conclusively saying that is all that is happening with EMdrive or Mach Effect but he thinks it is a significant error source for such tiny thrust measurements. Propellantless propulsion …

astronomy2,000-20,000 rogue Moon to Jupiter planets per main sequence star

No Comments
Previously, planets have been detected only in the Milky Way galaxy. Researchers show that quasar microlensing provides a means to probe extragalactic planets in the lens galaxy, by studying the microlensing properties of emission close to the event horizon of …
