Electronics Reliability In Space: Simulating Rad Hard Designs
By Aliyah Mallak - 10 Apr, 2025 - Comments: 0

Space is a harsh environment. There’s no breathable air, radiation levels are 15 times higher than on Earth, and the approximate temperature is 2.7 Kelvin (minus 270.45 degrees Celsius or minus 454.81 degrees Fahrenheit). Thankfully, Earth’s atmosphere does a great job protecting us from space’s intense climate. But because there is no atmosphere in space, there’s nothing to protect sat... » read more

Stakes Are High For Aerospace, Defense IC Designs
By Liz Allan - 03 Apr, 2025 - Comments: 0

Chips destined for the skies or armed forces need extra everything. They require higher layers of abstraction to simulate all the moving parts in the field, high-reliability testing for harsh environments, in addition to system-level test. They also need radiation-hardening and ceramic materials for space, extra safety layers, and advanced security techniques. As in the automotive sector, th... » read more

Pioneering The Cosmos With Physical AI: Robots Are Humanity’s Key Partners
By Steve Brown - 06 Mar, 2025 - Comments: 0

The stars have always fascinated us, sparking dreams of exploration and discovery. But now, as humanity steps further into the cosmos, a new hero takes center stage—physical AI. Robots, autonomous vehicles, and drones are transforming our ability to explore and settle other worlds, from navigating the alien terrain of Mars to constructing future bases on the Moon. These cutting-edge... » read more

FTIR On Earth, Mercury In Focus
By Xia Stammer - 08 Feb, 2024 - Comments: 0

On early hours on 19th October 2018 at Guiana Space Centre in Kourou in French Guiana an Ariane 5 rocket successfully launched the BepiColombo mission. It started its 7 years journey to Mercury. The joined mission of the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) was named in honor of Giuseppe “Bepi” Colombo, an Italian scientist who studied Mercury and fi... » read more

Understand The Physics Of Re-Entry Vehicles Using Numerical Modeling And Simulation
By Veena Parthan - 12 Oct, 2023 - Comments: 0

In the early years of space exploration, scientists and engineers dreamed of sending vehicles to Mars that could land on the planet's surface and explore its terrain. However, one of their biggest challenges was safely reentering the Martian atmosphere. Many early attempts at Mars missions failed because the vehicles either burned up during re-entry or crashed onto the surface. However, as tech... » read more

Stress tensor mesostructures for deterministic figuring of thin substrates
By Technical Paper Link - 21 Apr, 2022 - Comments: 0

New research paper from MIT and University of Arizona, funded by NASA. Abstract "Accessing the immense value of freeform surfaces for mass-sensitive applications such as space optics or metaform optical components requires fabrication processes that are suited to figuring thin substrates. We present stress tensor mesostructures for precisely correcting figure errors, even after microstruc... » read more

RT Kintex UltraScale FPGAs For Ultra High Throughput And High Bandwidth Applications
By Xilinx - 01 Dec, 2020 - Comments: 0

Xilinx's UltraScale architecture extends FPGA capability for space applications, delivering a step-function increase in I/O and memory bandwidth, capacity, performance, and in-orbit re-configurability. For the first time, the RT Kintex UltraScale XQRKU060 FPGA enables the satellite industry to access ultra-high throughput on-board processing of hundreds of Gb/s. This capability allows spacecraf... » read more

Far Out AI In Remote Locations
By SE Staff - 08 Sep, 2020 - Comments: 0

There really isn’t anything that you can do on Earth with electronics that you can’t do in space, but it certainly can be a lot harder and take longer to fix is something goes wrong. And as more intelligent electronics are launched into space, the concern over potential failures is growing. AI inferencing has been pushing out further for some time, and it is starting to redefine what con... » read more

Getting To Orbit And The Rocket Equation
By Paul McLellan - 05 Dec, 2019 - Comments: 0

The Apollo 12 mission recently celebrated its 50th anniversary. Launching on November 14, 1969 and returning on November 24, it put humans on the Moon for the second time. I wrote about Apollo 11 (mostly about its guidance computer) earlier in the year in my post The First Computer on the Moon. Today's post is about the rocket equation, and how challenging it is to get into orbit around th... » read more

Power/Performance Bits: Feb. 14
By Jesse Allen - 14 Feb, 2017 - Comments: 0

Electronics for Venus A team of scientists at NASA's Glenn Research Center in Cleveland demonstrated the first prolonged operation of electronics in the harsh conditions found on Venus. Current Venus landers can only operate on the planet's surface for a few hours due to the extreme atmospheric conditions. The surface temperature on Venus is nearly 860 degrees Fahrenheit, and the planet h... » read more
