SpaceX, L3Harris win Space Development Agency contracts to build missile-warning satellites

Posted by in categories: internet, military, satellites

SpaceX is developing a new satellite bus for the Space Development Agency based on the Starlink design.


WASHINGTON — The Space Development Agency awarded SpaceX a $149 million contract and L3Harris a $193.5 million contract to each build four satellites to detect and track ballistic and hypersonic missiles.

The contracts announced Oct. 5 are for the first eight satellites of a potentially much larger Space Development Agency constellation of sensor satellites known as Tracking Layer Tranche 0. This is SpaceX’s first military contract to produce satellites.

The Secret is Out: Scientists Figured Out How Tardigrades Became Immune to Radiation

Posted by in category: biological

Japanese researchers have discovered the secret to one of the tardigrade’s most impressive abilities. Tardigrades are immune to high levels of radiation and it’s all because of a protein. It turns out, human biology may be capable of developing it, too.

A quantum leap In the drug development world

Posted by in categories: biotech/medical, computing

Microfluidic chips that simulate human tissue enable us to conduct medical experiments in ways that could not have been even imagined only a few years ago. Two leading Israeli researchers report from the turbulent Israeli front line of the global ‘organ-on-a-chip’ sector.

Cognitive Electronic Warfare Could Revolutionize How America Wages War With Radio Waves

Posted by in categories: military, robotics/AI, space

The U.S. #military, like many others around the world, is investing significant time and resources into expanding its electronic #warfare capabilities across the board, for offensive and defensive purposes, in the air, at sea, on land, and even in space. Now, advances in #machinelearning and #artificialintelligence mean that electronic warfare systems, no matter what their specific function, may all benefit from a new underlying concept known as advanced “Cognitive Electronic Warfare,” or #Cognitive EW. The main goal is to be able to increasingly automate and otherwise speed up critical processes, from analyzing electronic intelligence to developing new electronic warfare measures and countermeasures, potentially in real-time and across large swathes of networked platforms.


The holy grail of this concept is electronic warfare systems that can spot new or otherwise unexpected threats and immediately begin adapting to them.

SkyWatch and Picterra combine imagery access with AI tools

Posted by in categories: business, information science, robotics/AI, satellites

SkyWatch Space Applications, the Canadian startup whose EarthCache platform helps software developers embed geospatial data and imagery in applications, announced a partnership Oct. 5 with Picterra, a Swiss startup with a self-service platform to help customers autonomously extract information from aerial and satellite imagery.

“One of the things that has been very difficult to achieve is this ability to easily and affordably access satellite data in a way that is fast but also in a way in which you can derive the insights you need for your particular business,” James Slifierz, SkyWatch CEO told SpaceNews. “What if you can merge both the accessibility of this data with an ease of developing and applying intelligence to the data so that any company in the world could have the tools to derive insights?”

SkyWatch’s EarthCache platform is designed to ease access to aerial and satellite imagery. However, SkyWatch doesn’t provide data analysis.

China pushes ahead with giant 13,000 satellite LEO constellation

Posted by in categories: internet, policy, satellites, space

China is pushing ahead with developing a giant Low Earth Orbit (LEO) satellite constellation competing with SpaceX, Amazon and OneWeb, according to the Washington DC-based analyst Bhavya Lal and California State University’s Professor Larry Press.

Press, professor of information systems at the California State University, mentioned a recent Chinese spectrum filing in a blog of the CircleID website. China “has filed a spectrum application with the International Telecommunication Union for two constellations with the cryptic names GW-A59 and GW-2″ for a total of 12,992 satellites, Press said.

“We heard about an announcement of a constellation with nearly 13,000 satellites,” Bhavya Lal said in SpaceWatchGlobal’s Space Café webtalk last week. Lal is a senior space policy analyst at the IDA Science and Technology Policy Institute in Washington DC and was in the lead for IDA’s recently published report “Evaluation of China’s Commercial Space Sector”.

High throughput screening identifies molecules that reduce cellular stress

Posted by in categories: biotech/medical, life extension

For many, getting older can unfortunately mean an increased risk of illness from cardiovascular disease to cancer. University of Michigan scientists are actively researching the biological underpinnings of aging with the aim of developing interventions that could potentially help people live longer, healthier lives.

A new paper in the journal Science Advances describes the discovery of several promising small molecules that appear to reduce in mouse skin and could lengthen life.

“Cellular resistance appears to be a common feature of long-lived organisms, such as invertebrates and mice,” says the paper’s lead author David Lombard, M.D., Ph.D., associate professor of pathology. Lombard is part of a multidisciplinary group at U-M’s Paul F. Glenn Center for Aging. Recent research from colleague and fellow study author Richard Miller, M.D., Ph.D., found several promising drugs, including rapamycin, a cancer drug, and acarbose, a diabetes drug, that extended life in mice.
