SpaceX Starship Raptor Engine breaks Russian rocketry record held for two decades SpaceX CEO Elon Musk says the company’s Raptor engine, meant to power Starship and Super Heavy, has surpassed a rocketry record held by Russian scientists and engineers for more than two decades. Known as combustion chamber pressure, Raptor has reportedly surpassed a modern Russian engine known as the RD-180, reaching forces equivalent to one Tesla Model 3 balanced on every square inch of Raptor’s combustion chamber, the hardware directly adjacent to a rocket engine’s bell-shaped nozzle. Keeping that in mind, in this video, Engineering Today will discuss about combustion chamber pressure of SpaceX Raptor engine as well as Russian, R D-1 80. Why Elon Musk think, Raptor can truly outperform the R D-1 80 in near future? Let’s get into details.
Is automated safety going too far? Apparently, there was a screw-like device found in the wreckage in Ethiopia that has provided investigators with an early clue into what happened. This jackscrew was used to set the trim that raises and lowers the plane’s nose. It indicates the jet was configured to dive. This evidence persuaded U.S. regulators to ground the model. There are a lot of added features that pilots were not fully aware of.
Even in our cars, there are features they do not tell you about. I have a Porsche. I pulled into my driveway and shut off the car but the stick was not completely in the park position. When I came out the next day, the battery was dead. My neighbor found the same thing happens when he travels. He has to keep his car plugged in because even when these newer cars are turned off, they are not completely off. It is still running programs and reporting back to a central computer. This is like Windows, which constantly wants to update so it can extract all your searching. Why does a car need to always be in touch with the manufacturer to the point that you cannot go on a trip and come back a couple of weeks later without discovering your battery is dead? Do we have to pop the hood and disconnect the battery before we take a trip?
Technology has advanced, but it is now being abused.
Sally Le Page traverses the weird and wonderful world of evolution and reproduction, with regular musical interludes along the way. This talk includes references to sex and has some mild language.
Are all males cheats? What do women want? And why should they do all the choosing anyway? What’s the largest number of children born to any woman? Join Sally Le Page on a light-hearted romp through the bizarre jungle of animal (and human) sex lives. She leads the audience through the evolutionary adventure of sex, from sexual conflict and the male frogs that sometimes hug a little too hard, to the supportive bush cricket spouses that feed and care for their mates. Sally explores mind controlling sperm, penguin prostitution, and how jealousy can affect sperm production.
Judith Mank leads a tour of how sex is genetically programmed and how sex differences evolve. Watch the Q&A here: https://www.youtube.com/watch?v=v-DRO… Subscribe for regular science videos: http://bit.ly/RiSubscRibe Males and females in many species are often quite different from one another. The sex of an individual can have profound effects on how an organisms behaves, how it looks, how it lives and, in some cases, even how it dies. These differences are the product of different evolutionary forces acting on males and females, sometimes creating substantial conflicts between the sexes. In this talk, Judith Mank gives a quick tour of how sex is genetically programmed and how sex differences evolve.

She is interested in understanding how form, behaviour and reproductive patterns have evolved through selective pressures.

Following two similar plane crashes in Indonesia (Oct ’18) and Ethiopia (March ’19) President Trump has issued an emergency order grounding a specific Boeing 737 airliner. The “Max 8” and “Max 9” models are being grounded out of an abundance of caution while U.S. and international authorities await the findings from crash investigation.
.
WASHINGTON (AP) — The U.S. is issuing an emergency order Wednesday grounding all Boeing 737 Max 8 and Max 9 aircraft “effective immediately,” in the wake of the crash of an Ethiopian Airliner that killed 157 people, President Donald Trump said.
“All of those planes are grounded, effective immediately,” Trump said during a scheduled briefing on border security.
Trump said any airplane currently in the air will go to its destination and then be grounded. He added all airlines and affected pilots had been notified.
Trump said the safety of the American people is of “paramount concern,” and added that the FAA would soon put out a statement on the action.
Trump said the decision to ground the aircraft “didn’t have to be made, but we thought it was the right decision.”
The president insisted the announcement was coordinated with aviation officials in Canada, U.S. carriers and aircraft manufacturer Boeing.
“Boeing is an incredible company,” Trump said. “They are working very, very hard right now and hopefully they’ll quickly come up with an answer.” (AP Report Link)
Prior to this decision, it appeared that Boeing was concerned about a specific element to flight software – SEE HERE:
BOEING – March 11, 2018 […] For the past several months and in the aftermath of Lion Air Flight 610, Boeing has been developing a flight control software enhancement for the 737 MAX, designed to make an already safe aircraft even safer. This includes updates to the Maneuvering Characteristics Augmentation System (MCAS) flight control law, pilot displays, operation manuals and crew training. The enhanced flight control law incorporates angle of attack (AOA) inputs, limits stabilizer trim commands in response to an erroneous angle of attack reading, and provides a limit to the stabilizer command in order to retain elevator authority.
Boeing has been working closely with the Federal Aviation Administration (FAA) on development, planning and certification of the software enhancement, and it will be deployed across the 737 MAX fleet in the coming weeks. The update also incorporates feedback received from our customers.
The FAA says it anticipates mandating this software enhancement with an Airworthiness Directive (AD) no later than April. We have worked with the FAA in development of this software enhancement.
[…] A pitch augmentation control law (MCAS) was implemented on the 737 MAX to improve aircraft handling characteristics and decrease pitch-up tendency at elevated angles of attack. It was put through flight testing as part of the certification process prior to the airplane entering service. MCAS does not control the airplane in normal flight; it improves the behavior of the airplane in a non-normal part of the operating envelope. (read more)

Ever since SpaceX tweeted this photo on September 13th, 2018, a lot of people fear the BFR is slowly turning into the space shuttle. Quoting ever growing wings and a giant heat shield covering the belly of the ship… so how is this any different than the Space Shuttle? Today we’ll to cover three topics. First, we’ll compare the reentry of the space shuttle to the reentry of the BFS and show how they differ. Then we’ll explain what control surfaces allow the BFS to perform this reentry, and then we’ll compare the thermal protection systems of the Shuttle and the BFS.
