The Good News Buried in Thursday ’s Soyuz Rocket Failure

One of the most technologically beautiful things you’ll ever see is a Soyuz rocket screwing up. Soyuz rockets don’t screw up often — another beautiful thing — but one did Thursday at 2:40 PM local time, over the steppes of Kazakhstan. What unfolded was a master class in how things go right when things go wrong. The rocket was intended to carry veteran Russian cosmonaut Alexey Ovchinin and rookie NASA astronaut Tyler “Nick” Hague up to low-Earth orbit for a six month stay aboard the International Space Station (ISS), joining a crew of two astronauts and one cosmonaut already aboard. Two and a half minutes after launch, the four clusters of engines that surround the rocket’s core stage shut down and fell away as they are designed to do. The central core was then supposed to ignite and then carry the crew further. That procedure is always a jolt for the crew, and a live-streaming camera inside the Soyuz spacecraft indeed showed Ovchinin and Hague getting knocked around a bit. But the knocking continued, and then Ovchinin called down “failure of the booster,” according to a CBS transcript. It’s not clear yet what that failure was, but video taken from the ground showed the four clusters tumbling through the sky, which is normal, along with other unidentified debris, which isn’t. At that moment, small rockets attached to a slender tower at the top of the Soyuz spacecraft that houses the crew did precisely what they...

NickersonAbstractReducing the sodium content of bread to meet desirable population health outcomes can lead to challenges dough processing, poor dough handling and rheology, and high stickiness. Our objective was to better understand the relationship of water and the dough components in low sodium dough environments. The water mobility, association, and diffusion characteristics of simple model doughs containing reduced NaCl (1% by flour wt.), organic acids (acet...

In this study, the thermal degradation behavior of P(3HB-co-3MP) was investigated to understand the characteristic features of thermostable thioester linkage. To this end, P(3HB-co-3MP) copolymers were biosynthesized using Ralstonia eutropha H16 supplemented with 3,3′-dithiodipropionic acid as the 3 MP precursor. First, the comonomer composition, thermal properties, and crystalline component of the prepared copolymers were characterized by nuclear magnetic resonance, differential scanning calorimetry, and Fourier transform infrared spectroscopy, respectively. The change in molecular weight during repeated melting o...

Controlled corundum grains were obtained tightly arranged crystal structure by controlling the rate of Al2O3 dissolution-precipitation process through magnesium ore addition in ceramic system. At the same time, the size of the pores was controlled by adjusting the content of the liquid phase in the sys...
