Gallium nitride processor: Next-generation technology for space exploration

Posted by in categories: computing, engineering, space travel

A material known as gallium nitride (GaN), poised to become the next semiconductor for power electronics, could also be essential for various space applications. Yuji Zhao, an expert in electrical and computer engineering at Arizona State University (ASU), plans to develop the first ever processor from gallium nitride, which could revolutionize future space exploration missions.

Gallium nitride is a semiconductor compound commonly used in light-emitting diodes (LEDs). The material has the ability to conduct electrons more than 1,000 times more efficiently than silicon. It outstrips silicon in speed, temperature, power handling, and is expected to replace it when silicon-based devices will reach their limits.

Besides LEDs, GaN can be used in the production of semiconductor power devices as well as RF components. Now, Yuji Zhao aims to use this material to develop a high-temperature microprocessor for space applications. He received a three-year $750,000 grant from NASA’s Hot Operating Temperature Technology (HOTTech) program for his project.

NASA Planning Mission to Alpha Centauri—in 2069

Posted by in category: space travel

NASA is prepping for a trip to the nearby three-star Alpha Centauri system—in 2069.

That’s my kind of advanced planning.

The mission, first announced by New Scientist, would include a 44-year-long expedition to an exoplanet in search of signs of life. Assuming NASA’s Jet Propulsion Laboratory (JPL) can figure out how to travel at a tenth of the speed of light.

Falcon Heavy raised on pad 39A for first time

Posted by in category: space travel

SpaceX’s first Falcon Heavy rocket, made up of two previously-flown Falcon 9 boosters and a beefed up central core stage, made the trip to launch pad 39A at NASA’s Kennedy Space Center in Florida and was raised vertical Thursday for testing ahead of its first liftoff next month.

The fully-assembled 229-foot-tall (70-meter) rocket will be the most powerful in the world when it blasts off, and Thursday’s arrival atop pad 39A marks a major step toward readying the Falcon Heavy for flight.

SpaceX engineers are expected to conduct a fit check and complete other tests at pad 39A this week, followed by a hold-down firing of all 27 first stage engines some time after New Year’s Day. The company has not set a target date for the Falcon Heavy’s first liftoff, but officials say the launch is targeted in January, some time after the hold-down hotfire test.

SpaceX BFR construction will start in 4 to 6 months

Posted by in category: space travel

The SpaceX BFR (Big Falcon Rocket or Big Fucking Rocket) has a planned payload of 150,000 kg (330,000 lb) when flying reusable or 250,000 kg (550,000 lb) when flying expendable, making it a super heavy-lift launch vehicle.

SpaceX plans to replace of all their current rockets by the early 2020s with the BFR. Tooling for the main tanks has been ordered and a facility to build the vehicles is under construction; construction of the first BFR is scheduled to begin in the second quarter of 2018. SpaceX has the aspirational goal for initial Mars-bound cargo flights of BFR launching as early as 2022, followed by the first crewed BFR flight one synodic period later, in 2024. Serious development of the BFR began in 2017.

Testing of the BFR is expected to begin with short suborbital hops of the full-scale ship, likely to just a few hundred kilometers altitude and lateral distance.

First Image of Elon Musk’s Tesla Roadster getting ready to go to Mars on a SpaceX rocket

Posted by in categories: Elon Musk, space travel, sustainability

There have been a lot of doubts and confusion around Elon Musk’s claim that the first payload of SpaceX’s new Falcon Heavy will be his own original Tesla Roadster.

But now it looks more real than ever as we get to see the first image of the electric vehicle being turned into a payload.

Canadian QEYSSat Quantum Satellite Program Gets Next Round of Funding

Posted by in categories: economics, encryption, government, quantum physics, space travel

The Canadian Space Agency (CSA) has awarded $1.85M contract to the University of Waterloo for the Quantum Encryption and Science Satellite (QEYSSat) mission.

The QEYSSat mission was one of two projects cited in the 2017 budget when it was unveiled in March of this year. In April, the government sent Innovation Science and Economic Development (ISED) Minister Navdeep Bains to the CSA’s headquarters to formally announce the funding for the QEYSSat mission along with funding for a radar instrument that will be developed for a future orbiter mission to Mars and to announce the Canadian CubeSat Project. The $80.9M of funding would be over five years.

A short history of the QEYSSat mission.
