This is an incredibly naive approach. All asteroids emit light in the infrared, to detect and track asteroids just takes an infrared telescope making apparent motion against any background completely irrelevant. NASA is working on this: ht

Fatigue is why we use steel for everything, no other alloys have the practical strength and infinite life.

Not all asteroids are “bright” enough to be imaged from earth, the problem is the low albedo asteroids you cant see, thats why we need this: https://solarsystem.nasa.gov/missions/neo-surveyor/in-depth/

Running the case this hot will degrade the battery significantly faster, hot battery reduces short term capacity and hot battery reduces lifetime capacity. MacBook(2015) has similar issues.

inkl.com has been around a lot longer than “apple news” and seems to have much more news sources. Im going to be voting for the underdog with my money.

Canada? Or Common Wealth? Judging from how you spell “cheque”. Signatures still mean something in some countires, just not the US.

imo the best way to combat this is to answer the call and waste as much of the scammers time as possible. Call spamming only scales because most people ignore or hangup immediately. If you waste 30seconds of a scammers time thats 30 more pe

only the exterior blankets would have such extreme temperature cycles, the inner aluminum hull would have a much more stable temperature. The diurnal would be much more benign. Still enough for CTE and fatigue to cause a failure.

NASA’s box requirement is 70C. That means the ICs in the box are much hotter, parent is probably refering to IC temp, not unit.

ULA has 100% mission success. The Atlas family has 100% mission sucess since 1957. The ULA markup is justified for a high value mission. BO and spaceX have big shoes to fill when it comea to building industry and insurer trust. The Amos 8 f

I understand the root issues is Amtrack unions. Amtrack staffing is one employee to four passengers. I dont know what the ratio is for airlines but it must be lower. This video does a pretty good explonation i think: https://m.yo

It really is. The bottom line is these sensors can scale to small sizes unlike watch batteries enabling remote sensing and integrated manufacturing. Think temperature sensors inside that watch battery. Strain sensors in existing and future

Same principle in that they both use electromagnetism, yes. But Qi and similar wireless charging using inductively couples coils. WISP power is generated from radio waves absorbed by the antenna generating a small current then boosted to a

what is there to attack? if someone is in range to get the backscattered signal they can just see what the camera is looking at...its 16ft LOS, for privacy concerns at such low powers any walls would attenuate the backscatter.

The new batteryless wireless sensors coming out of uw are incredible. Dr. Smith is leading some great work. My interest started when I heard of the WISP [0]. The RF power harvesting design is so simple and elegant. It is amazing what can be
