Raptor and BE4SpaceX and Blue Origin have been competing with each other for many space crafts and commercial contracts. We have also talked about their rivalry many times but today is all about their engines that fire up the massive rockets both the companies are developing. SpaceX, the leading space company has made many rocket engines since its launch in 2002. A few months ago, SpaceX completed its 100th Raptor Engine. This extraordinary milestone was achieved in just 29 months. Blue Origin’s rocket engines game started work on the BE-4 in 2011. Importantly, they said the “BE-4 would be ‘ready for flight’ by 2017″, but at this moment Blue Origin’s powerful BE-4 engine is more than four years late. The first flight test of the new engine is now expected no earlier than 2022 on the Vulcan rocket. This is a big problem and we need to talk about that.
So, How did Blue Origin’s BE-4 turn into a joke whereas SpaceX’s Raptor is the leading example?
Let’s find out:
Firstly, how has BE-4 gone through almost a decade of failure?
This was their first engine to combust liquid oxygen and liquified natural gas propellants. It was initially planned for the engine to be used exclusively on a Blue Origin proprietary launch vehicle New Glenn, the company’s first orbital rocket. However, it was announced in 2014 that the engine would also be used on the United Launch Alliance (ULA) Vulcan Centaur launch vehicle, the successor to the Atlas V launch vehicle. This was labeled “a stunner” choice. The company planned to begin full-scale engine testing in late 2016 and expected to complete the development of the engine in 2017.However, the first engine was not fully assembled until March 2017. Also, in March, United Launch Alliance indicated that the economic risk of the Blue Origin engine selection option had been retired, but that the technical risk on the project would remain until a series of engine firing tests were completed later in 2017. A test anomaly occurred on 13 May 2017 and Blue Origin reported that they lost a set of powerpack hardware.
SpaceX’s Raptor Engines completely HUMILIATED Blue Origin BE-4 Engines!!

Researchers at the University of California, Berkeley, have successfully revived human heart tissue after it had been preserved in a subfreezing, supercooled state for up to three days.

A truck fleet accident costs an average of $16,500 in damages and $57,500 in injury-related costs for a total of $74,000. “This does not include a broad range of ‘hidden’ costs, including reduced vehicle value (typically anywhere from $500 to $2,000), higher insurance premium, legal fees, driver turnover (the average driver replacement cost = $8,200), lost employee time, lost vehicle-use time, administrative burden, reduced employee morale and bad publicity,” said Yoav Banin, chief product officer at Nauto, which provides artificial intelligence driver and fleet performance solutions.

Emphasis on truck driving safety is well placed, considering other challenges that the trucking industry is facing.

Ranking first is a chronic shortage of truck drivers nationwide that could force fleet operators to hire less-experienced drivers who require operator and safety training. Driver compensation and truck parking ranked second and third, but immediately behind them in fourth and fifth position were driver truck fleet safety and insurance availability, which depends on safe driving records.

Artificial intelligence expert Timnit Gebru on the challenges researchers can face at Big Tech companies, and how to protect workers and their research.

Artificial intelligence research leads to new cutting-edge technologies, but it’s expensive. Big Tech companies, which are powered by AI and have deep pockets, often take on this work — but that gives them the power to censor or impede research that casts them in an unfavorable light, according to Timnit Gebru, a computer scientist, co-founder of the nonprofit organization Black in AI and the former co-leader of Google’s Ethical AI team.

The situation imperils both the rights of AI workers at those companies and the quality of research that is shared with the public, said Gebru, speaking at the recent EmTech MIT conference hosted by MIT Technology Review.

China is pulling ahead of global rivals when it comes to innovative AI “unicorns” that are pushing the technology forward. Research from GlobalData has found that — of the 45 international AI unicorns identified — China has the largest share with 19 based in the country.

Collectively, the Chinese AI unicorns are valued at $43.5 billion.

Beijing has been on a regulatory crackdown in recent months, especially on Chinese companies doing business in, and with, the US.

It’s been a hot, hot year in the world of data, machine learning, and AI. Just when you thought it couldn’t grow any more explosively, the data/AI landscape just did: the rapid pace of company creation, exciting new product and project launches, a deluge of VC financings, unicorn creation, IPOs, etc.

It has also been a year of multiple threads and stories intertwining.

One story has been the maturation of the ecosystem, with market leaders reaching large scale and ramping up their ambitions for global market domination, in particular through increasingly broad product offerings. Some of those companies, such as Snowflake, have been thriving in public markets (see our MAD Public Company Index), and a number of others (Databricks, Dataiku, DataRobot, etc.) have raised very largely (or in the case of Databricks, gigantic) rounds at multi-billion valuations and are knocking on the IPO door (see our Emerging MAD company Index).

Arm is releasing new chip design offerings in the internet of things (IoT), virtual hardware, and 5G sectors.

Cambridge, United Kingdom-based Arm designs the architecture that other licensed chip makers use to build their chips. Arm likes to make it easier for those licensees to come up with their applications and create a foundation for an IoT economy.

So the company said its Arm Total Solutions for IoT now delivers a full-stack solution to significantly accelerate the development and return-on-investment for IoT chip products. And Arm Virtual Hardware removes the need to develop on physical silicon, enabling software and hardware co-design and accelerating product design by up to two years, the company claimed.

Multidisciplinary team of materials physicists and geophysicists combine theoretical predictions, simulations, and seismic tomography to find spin transition in the Earth’s mantle.

The interior of the Earth is a mystery, especially at greater depths (660 km). Researchers only have seismic tomographic images of this region and, to interpret them, they need to calculate seismic (acoustic) velocities in minerals at high pressures and temperatures. With those calculations, they can create 3D velocity maps and figure out the mineralogy and temperature of the observed regions. When a phase transition occurs in a mineral, such as a crystal structure change under pressure, scientists observe a velocity change, usually a sharp seismic velocity discontinuity.

In 2,003 scientists observed in a lab a novel type of phase change in minerals — a spin change in iron in ferropericlase, the second most abundant component of the Earth’s lower mantle. A spin change, or spin crossover, can happen in minerals like ferropericlase under an external stimulus, such as pressure or temperature. Over the next few years, experimental and theoretical groups confirmed this phase change in both ferropericlase and bridgmanite, the most abundant phase of the lower mantle. But no one was quite sure why or where this was happening.
