Welcome to Edition 5.36 of the Rocket Report! A long time ago in a galaxy far, far away, the space media were given a May 4 launch date for United Launch Alliance’s Vulcan rocket. Alas, May the 4th, in 2023, wasn’t meant to be. In this week’s report, I explain why.

As always, we welcome reader submissions, and if you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Electron to serve as a hypersonics test bed. Rocket Lab’s small booster will use essentially the same first and second stages for hypersonic test flights, but it will have a modified kick stage that will allow Electron to deploy payloads with a mass of up to 600 kg into trajectories five times greater than the speed of sound, Ars reports. The Army, Navy, and Air Force are all developing hypersonic missiles to provide a fast-moving, maneuverable capability for striking targets quickly from thousands of kilometers away. Among the research problems the military likely wants to test is managing the extreme heat that hypersonic missiles are exposed to by traveling at high speeds in the atmosphere for most of their flight.

The WHO says covid is no longer an emergency, yet does not say where covid originated from. No one knows. What I know is that covid is a cute name for SARS/Coronavirus. Something made in a lab at UNC Chapel Hill with Ralph Baric and his collegue from Wuhan China which he shared his gain of function research with. However the Nature article published in 2015 has this disclaimer, yet there is no animal origin after more than 3 years. So what do we believe?

“30 March 2020 Editors’ note, March 2020: We are aware that this article is being used as the basis for unverified theories that the novel coronavirus causing COVID-19 was engineered. There is no evidence that this is true; scientists believe that an animal is the most likely source of the coronavirus.”

The results indicate that group 2b viruses encoding the SHC014 spike in a wild-type backbone can efficiently use multiple orthologs of the SARS receptor human angiotensin converting enzyme II (ACE2), replicate efficiently in primary human airway cells and achieve in vitro titers equivalent to epidemic strains of SARS-CoV. ACE2 🤔

Will new molecular bioprinting technologies soon allow us to print our DNA?

Other research points to a future when we will be able to print DNA, nucleotide by nucleotide.

Fusion reactor.

Without a doubt someday it is possible to have fusion power plants providing sustainable energy resolving our long-standing energy problems. This is the main reason so many scientists throughout the world are carrying out research on this power source. The generation of power from this method actually mimics the sun.

Researchers in Germany and the U.S. have shown for the first time that terahertz (THz) light pulses can stabilize ferromagnetism in a crystal at temperatures more than three times its usual transition temperature. As the team reports in Nature, using pulses just hundreds of femtoseconds long (a millionth of a billionth of a second), a ferromagnetic state was induced at high temperature in the rare-earth titanate YTiO₃ which persisted for many nanoseconds after the light exposure. Below the equilibrium transition temperature, the laser pulses still strengthened the existing magnetic state, increasing the magnetization up to its theoretical limit.

Using light to control magnetism in solids is a promising platform for future technologies. Today’s computers mainly rely on the flow of electrical charge to process information. Moreover, digital memory storage devices make use of magnetic bits that must be switched external magnetic fields. Both of these aspects limit the speed and energy efficiency of current computing systems. Using light instead to optically switch memory and computing devices could revolutionize processing speeds and efficiency.

YTiO₃ is a transition metal oxide that only becomes ferromagnetic, with properties resembling those of a fridge magnet, below 27 K or −246°C. At these low temperatures, the spins of the electrons on the Ti atoms align in a particular direction. It is this collective ordering of the spins which gives the material as a whole a macroscopic magnetization and turns it ferromagnetic. In contrast, at temperatures above 27 K, the individual spins fluctuate randomly so that no ferromagnetism develops.

The machine, which weighs only 22 lb (10 kg), is a single-piston-linear-engine, that runs exclusively on hydrogen. As it has only 20 components and one moving part, the engine is also much cheaper to produce and maintain than traditional engines.

An AI-powered ‘brain decoder’ can now read your thoughts with surprising accuracy.

Servers running software sold by Salesforce are leaking sensitive data managed by government agencies, banks, and other organizations, according to a post published Friday by KrebsOnSecurity.

At least five separate sites run by the state of Vermont permitted access to sensitive data to anyone, Brian Krebs reported. The state’s Pandemic Unemployment Assistance program was among those affected. It exposed applicants’ full names, Social Security numbers, addresses, phone numbers, email addresses, and bank account numbers. Like the other organizations providing public access to private data, Vermont used Salesforce Community, a cloud-based software product designed to make it easy for organizations to quickly create websites.

Another affected Salesforce customer was Columbus, Ohio-based Huntington Bank. It recently acquired TCF Bank, which used Salesforce Community to process commercial loans. Data fields exposed included names, addresses, Social Security numbers, titles, federal IDs, IP addresses, average monthly payrolls, and loan amounts.

Located in Fort Lauderdale, the French country-style homes have their own pools, but share the bass-stocked lake between them.
