Dr. Michael Roberts, Ph.D. — Chief Science Officer, International Space Station National Laboratory

Dr. Michael Roberts, Ph.D. is Chief Science Officer of the International Space Station National Laboratory (https://www.issnationallab.org/), and Vice President at the Center for the Advancement of Science in Space (CASIS — https://www.issnationallab.org/about/center-for-the-advancem…dership/), which as manager of the ISS National Laboratory in partnership with NASA, is responsible to the nation for enabling access to the International Space Station for research, technology development, STEM education, and commercial innovation in space as a public service to foster a scalable and sustainable low Earth orbit economy.

Before joining CASIS in 2013, Dr. Roberts worked as a microbial ecologist, principal investigator, and research group lead in the NASA Advanced Life Support program at the Kennedy Space Center.

Prior to arriving at NASA-KSC in 1999, Dr. Roberts completed an undergraduate degree in biology at Maryville College, a doctorate in microbiology at Wesleyan University and post-doctoral research at the Center for Microbial Ecology at Michigan State University and the RIKEN Institute in Wako-shi, Japan.

Hydrogen peroxide found on Jupiter’s moon Ganymede in higher latitudes

An international team of space scientists has found evidence that hydrogen peroxide on Ganymede, Jupiter’s largest moon, exists only on its higher latitudes. For their research, reported in the journal Science Advances, the group studied data from the James Webb Space Telescope (JWST).

For many years, researchers theorized that hydrogen peroxide existed on Ganymede, but it took a prior team studying data from the JWST to find it. In this new effort, the research team analyzed new data sent back by the telescope to learn more about the and its hydrogen peroxide.

Ganymede is the largest moon in the solar system, but it has not received nearly the attention given to another of Jupiter’s moons, Europa, whose features and characteristics make it far more likely to have harbored life at some point in time. But prior research has shown that the influence of Jupiter’s magnetic field on many of its moons could indicate a strong probability of hydrogen peroxide on Ganymede. This is because of its likely impact on the water-ice irradiation process on its surface.

Recycle Spent Nuclear Fuel Save the Grid with Steven Curtis

Make nuclear power safer by tapping the gold mine in the spent fuel rods by using molten salt reactors and small modular reactors for both safe nuclear plant back up power and for microgrids that will be less susceptible to an EMP or CME E3 waveform. Watch to learn!

Scientists find evidence of ‘very recent’ running water flowing on Mars

Gullies on the slopes of Martian craters were likely created by the “very recent” flow of water, according to a new study that sheds more light on whether life could exist on the Red Planet.

The presence of life on a planet, as it is seen on Earth, goes hand in hand with the existence of liquid water.

Researchers have previously shown that there may have been past periods on Mars when liquid water likely formed gullies if Mars tilted enough on its axis.

Scientists use chemical mapping to study the spiraling arms of the Milky Way

A researcher has used the technique of chemical mapping to study the spiral arms of our home galaxy: the Milky Way. According to Keith Hawkins, assistant professor at The University of Texas at Austin, chemical cartography might help us better grasp the structure and evolution of our galaxy.

“Much like the early explorers, who created better and better maps of our world, we are now creating better and better maps of the Milky Way,” mentioned Hawkins in an official release.

The world’s fastest supercomputer with a processing power of 4 exaflops unveiled

The supercomputer is part of the larger constellation of inter-connected supercomputers with a combined capacity of 36 exaFLOPS.

Abu Dhabi-based technology holding group G42 has unveiled the world’s fastest supercomputer, the Condor Galaxy-1 (CG-1), which has 54 million cores and a processing capacity of four exaflops, a press release said. The supercomputer is located in Santa Clara, California, and will be operated by Cerebras, a US-based AI firm under US laws.

As artificial intelligence (AI) technology takes center stage, there is a strong demand for supercomputers to help businesses train their own models. Companies like Microsoft have offered to build the extremely expensive infrastructure and rent it out for companies to work on them.

Cerebras Systems signs $100 million AI supercomputer deal with UAE’s G42

July 20 (Reuters) — Cerebras Systems on Thursday said that it has signed an approximately $100 million deal to deliver the first of what could be up to nine artificial intelligence (AI) supercomputers in a partnership with United Arab Emirates-based technology group G42.

The deal comes as cloud computing providers around the world are searching for alternatives to chips from Nvidia Corp (NVDA.O), the market leader in AI computing whose products are in short supply, thanks to the surging popularity of ChatGPT and other services. Cerebras is one of several startups looking to challenge Nvidia.

Silicon Valley-based Cerebras said that G42 has agreed to purchase three of what it calls its Condor Galaxy systems, all of which it will build in the U.S. to speed up the roll out. The first one will come online this year, with two more coming in early 2024.
