The achievement opens a pathway for development of the first practical and efficient devices to generate and detect light at terahertz wavelengths—between infrared light and microwaves. Such devices could be used in applications as diverse as communications in outer space, cancer detection, and scanning for concealed weapons.

The research could also enable exploration of the basic physics of matter at infinitesimally small scales and help usher in an era of quantum metamaterials, whose structures are engineered at atomic dimensions.

Many exploration destinations in our solar system are frigid and require hardware that can withstand the extreme cold. During NASA ’s Artemis missions, temperatures at the Moon’s South Pole will drop drastically during the lunar night. Farther into the solar system, on Jupiter ’s moon Europa, temperatures never rise above −260 degrees Fahrenheit (−162 degrees Celsius) at the equator.

One NASA project is developing special gears that can withstand the extreme temperatures experienced during missions to the Moon and beyond. Typically, in extremely low temperatures, gears – and the housing in which they’re encased, called a gearbox – are heated. After heating, a lubricant helps the gears function correctly and prevents the steel alloys from becoming brittle and, eventually, breaking. NASA’s Bulk Metallic Glass Gears (BMGG) project team is creating material made of “metallic glass” for gearboxes that can function in and survive extreme cold environments without heating, which requires energy. Operations in cold and dim or dark environments are currently limited due to the amount of available power on a rover or lander.

Virgin Galactic plans to conducts its next crewed spaceflight test on Oct. 22, according to documents the company filed with the Federal Communications Commission on Tuesday.

The flight will be the first of two that the space tourism company has planned to complete testing of its SpaceShipTwo spacecraft system and should have just two test pilots on board. Virgin Galactic said last month that the second test spaceflight will then have four “mission specialists” inside the cabin. If both test flights succeed, Virgin Galactic expects to fly founder Sir Richard Branson in the first quarter of 2021 – a milestone that will mark the beginning of the company’s commercial tourism service.

Shares of Virgin Galactic closed down 3.7% on Friday at $15.92 a share.

With two successful 150-meter hops in the bag for SpaceX, Starship testing is preparing to enter the next phase. Starship SN6’s successful 150-meter hop followed just weeks after SN5’s achievement.

While SN5 is preparing to conduct another leap, Starship SN8 is closing in on its maiden flight, this time sporting three Raptor engines, a nosecone, and aero surfaces – likely to come after additional data is gathered via the upcoming SN7.1 Test Tank “Burst Test.”

“It will provide more convenient and cheaper transport for the peaceful use of space in the future.”

SpaceX is rapidly manufacturing multiple Starship prototypes at the South Texas facility located in Brownsville’s Boca Chica beach. An orbital-class Starship will be equipped with six powerful Raptor engines. Raptors are fueled by cryogenic methane and liquid oxygen which is a unique fuel combination in the aerospace industry. Each Raptor is capable of producing over 200 tons, or 2MN (meganewtons), of thrust at full throttle. Three of Starship’s Raptors will be sea-level engines for atmospheric flight, and three vacuum-optimized Raptors for propulsion in space. Vacuum-optimized engines are more complex and different than sea-level engines; they’re specifically designed to have a higher performance in the vacuum of space. A visible difference between the two engines is that the bell nozzle is larger in the Raptor vacuum engine. Today, SpaceX shared a photograph showcasing the gigantic Raptor vacuum engine, pictured below.

Chief Engineer Elon Musk founded SpaceX with the goal to enable humans to live on Mars. The aerospace company is developing its next-generation launch vehicle in South Texas at Boca Chica Beach. According to SpaceX, Starship will be the most powerful rocket in the world; It will be a 120-meter-tall, two-stage launch vehicle consisting of a spacecraft capable of carrying one hundred passengers, and a Super Heavy booster used to propel the craft out of Earth’s atmosphere.

During the Humans To Mars teleconference that took place on Tuesday, Musk said Starship’s Super Heavy “booster prototype one” will initiate construction “this week.” SpaceX Boca Chica teams are building multiple Starship prototypes at the assembly facility, where gigantic vehicle assembly buildings are taking shape to accommodate the massive stainless-steel rocket booster. – “Making a prototype of something is, I think, relatively easy,” he said, “But building the production system so that you can build ultimately hundreds or thousands of Starships, that’s the hard part.”

Just playing around with the SpaceX footage from last nights SN6 hop. Enlarged and enhanced the video so we could zoom in on SN6 and the 2nd half of the video I slow it down X5.
