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.

In-Space Manufacturing Is About to Get a Big Test

Posted by in categories: 3D printing, space travel

A bold plan to rev up off-Earth manufacturing is about to get a big test.

A small, privately built machine designed to make optical fiber is launching toward the International Space Station (ISS) aboard SpaceX’s Dragon cargo capsule tomorrow (Dec. 12).

If all goes according to plan, this little factory — which is owned by California-based startup Made In Space — will churn out stuff that’s good enough to sell here on Earth, opening up space to greater commercial use. [3D Printing: 10 Ways It Could Transform Space Travel].

AI is now so complex its creators can’t trust why it makes decisions

Posted by in categories: robotics/AI, space travel

Artificial intelligence is seeping into every nook and cranny of modern life. AI might tag your friends in photos on Facebook or choose what you see on Instagram, but materials scientists and NASA researchers are also beginning to use the technology for scientific discovery and space exploration.

But there’s a core problem with this technology, whether it’s being used in social media or for the Mars rover: The programmers that built it don’t know why AI makes one decision over another.

Modern artificial intelligence is still new. Big tech companies have only ramped up investment and research in the last five years, after a decades-old theory was shown to finally work in 2012. Inspired by the human brain, an artificial neural network relied on layers of thousands to millions of tiny connections between “neurons” or little clusters of mathematic computation, like the connections of neurons in the brain. But that software architecture came with a trade-off: Since the changes throughout those millions of connections were so complex and minute, researchers aren’t able to exactly determine what is happening. They just get an output that works.
