New Evidence Found which Matches Legendary Founding of the First Dynasty of China

A archaeological team from Beijing University have found new evidence that surprisingly fits the ancient Chinese histories’ accounts of the founding of the Xia Dynasty. Previously, historians had dismissed all accounts of the first, second, and third dynasties as fabrications. They were written to glorify the dynasties which came later, not to document what had really happened. But archaeological findings over the last century provided evidence that the second and third dynasties had really existed. The Shang Dynasty you likely heard about in schools. Yup, we had once thought it was a myth. Now science and archaeology may be confirming the earliest dynasty written about existed as well. Read more

My question is, is the IDA going to be a standard for spacecraft? Do we have standard ports already?

Spacewalk Friday: Installing a New "Parking Spot" on Station

This Friday, Aug. 19, two U.S. astronauts will install a new gateway for American commercial crew spacecraft at the International Space Station. 

Commercial crew flights from Florida’s Space Coast to the International Space Station will restore America’s human spaceflight launch capability and increase the time U.S. crews can dedicate to scientific research.

The adapter being installed (imaged below) was launched on a SpaceX Dragon cargo spacecraft and arrived on orbit July 20. This ring is known as an International Docking Adapter, or IDA, and its main purpose is to provide a port for spacecraft bringing astronauts to the station in the future. Outfitted with a host of sensors and systems, the adapter is built so spacecraft systems can automatically perform all the steps of arrival and docking with the station without input from the astronauts. 

NASA astronauts Jeff Williams and Kate Rubins will perform the spacewalk to install the equipment this Friday, Aug. 19. This will be the fourth spacewalk in Williams’ career and the first for Rubins.

Four previous spacewalks…like the one below…helped set the stage for installation of this docking adapter. During those previous spacewalks, other crew members laid hundreds of feet of power and data cables outside the space station. 

On Wednesday, the robotics team using the Canadarm2 and its attached “Dextre” manipulator, will reach into the SpaceX Dragon trunk and pull out the docking adapter and position it for Friday’s spacewalk activities.

The morning of the spacewalk, while the astronauts are getting suited up, the robotic arm will position the docking adaptor near the port so that it will be ready for installation.

The two astronauts will venture outside the space station to install the first International Docking Adapter (IDA). This new adapter port will provide a parking space for U.S. Commercial Crew vehicles.

Watch LIVE!

Coverage of the spacewalk begins at 6:30 a.m. EDT on Friday, Aug. 19; with the spacewalk scheduled to begin at 8:05 a.m. EDT. Stream live online HERE.

Happy Ada Lovelace day - here's why we should all remember her

Today is Ada Lovelace Day. Who's that? Just the first computer programmer. Ever.

Lovelace’s friend Charles Babbage designed a concept for a machine he called the “Analytical Engine” – essentially a mechanical computer that would have relied on punch cards to run programs. He recruited Lovelace to translate some notes from one of his lectures, but while Lovelace was translating she added to the notes herself.

The notes grew to three times their original length, as Lovelace described what many call the first computer program. Because of funding issues, the machine was not built during her and Babbage’s lifetimes.

But Lovelace’s published article on the Analytical Engine later became a source of inspiration for Alan Turing’s work to build the first modern computers in the 1940s.

Women are sometimes considered outsiders in the science and technology fields, but Lovelace and many of the female computer programmers who followed her are proof that this paucity is a function of society, not capability. We forget or never learn about the female “computers” who programmed early mechanical machines in World War II, or that the women’s magazine Cosmopolitan once ran articles suggesting that women were perfectly suited for programming.

If the lack of acknowledgement of women’s contributions to science, technology, engineering, and mathematics (STEM) fields grinds your gears, then Ada Lovelace should be one of the first names you go to right that wrong.
