Is a NASA Television broadcast from the Johnson Space Center in Houston featuring stories about NASA’s work in human spaceflight, including the International Space Station and its crews and scientific research activities, and the development of Orion and the Space Launch System, the next generation American spacecraft being built to take humans farther into space than they’ve ever gone before.
A method for employing sinusoidal oscillations of electrical bombardment on the surface of one Kerr type singularity in close proximity to a second Kerr type singularity in such a method to take advantage of the Lense-Thirring effect, to simulate the effect of two point masses on nearly radial orbits in a 2+1 dimensional anti-de Sitter space resulting in creation of circular timelike geodesics conforming to the van Stockum under the Van Den Broeck modification of the Alcubierre geometry (Van Den Broeck 1999) permitting topology change from one spacelike boundary to the other in accordance with Geroch’s theorem (Geroch 1967) which results in a method for the formation of G{umlaut over ()}odel-type geodesically complete spacetime envelopes complete with closed timelike curves.

Targeted Ariane 5 launch date for James Webb Space Telescope.
- Ariane 5 Flight VA256 launching the James Webb Space Telescope (Webb) is scheduled for December 18 2021, from the Guiana Space Center.
– Webb will be the largest, most powerful telescope ever launched into space.
– Webb is an international collaboration between the National Aeronautics and Space Agency (NASA), the European Space Agency (ESA) and the Canadian Space Agency (CSA).
NASA’s long-delayed James Webb Space Telescope is close to entering service. The agency now plans to launch the telescope on December 18th, 2,021 just a few months after testing completed in late August. The hardware will reach orbit aboard an ESA-supplied Ariane 5 rocket lifting off from French Guiana. NASA still has to ship the telescope to the launchpad, although much of the rocket has already arrived.
The JWST was deemed complete in 2016 ahead of an expected 2018 launch, but faced a number of delays due to its elaborate construction. It wasn’t assembled until 2019, and factors like the COVID-19 pandemic further hindered NASA’s efforts. That’s not including earlier setbacks — development started in 1996 with an expected 2007 deployment, but the team scrapped much of its work and redesigned the equipment in 2005.
The telescope’s importance hasn’t changed. It’s considered the successor to the Hubble Space Telescope. It includes a much larger mirror along with a focus on lower-frequency observations (particularly mid-infrared) that will help it detect early galaxies that even Hubble can’t find. That priority also helps explain some of its technical challenges. The JWST’s instruments will need to stay extremely cold (−370F) to avoid interference with infrared measurements, requiring both a large sunshield and an insertion near a Sun-Earth Lagrange point.

War has been a part of the human experience since the beginning of civilization. But new technologies are changing the face of warfare in ways that we never really expected. From cyberwarfare to autonomous AI-piloted drones to space warfare, the future of war is weird. And terrifying.
