Reminder from Mars: This Is Rocket Science ; Failure Shows How Hard It Is to Explore SpaceNight after sleep-deprived night, NASA scientists crowded into tiny Room 225, the Mars Operation Center at NASA's Jet Propulsion Laboratory in Pasadena, Calif., and scanned the skies for overdue signals...
Working out how life originated is hard. And rocket science is said to be tricky too! But that hasn't stopped aerospace engineers figuring out how to make rockets, how to guide them, and beyond that, to produce all kinds of variants and improvements in precision and accuracy, even though ...
Interest is the best teacher. Yan likes space science very much. He works hard and wants make rockets for our country one day. 1. Why do people call Yan "rocket boy"?(不超过10个词)2. Where do Yan's parents take him every weekend? (不超过10个词)3...

Accelerometers are the stuff of rocket science—quite literally! Mounted in spacecraft, they're a handy way to measure not just changes in rocket speed but also apogee (when a craft is at its maximum distance from Earth or another mass, so its acceleration due to gravity is at a minimum)...
who I fund as a venture capitalist, are incredible workers, amazing work ethic. My example in the delivery room is nothing compared to how hard people work in China. As an example, one startup tried to claim work-lif...
There has also been a good bit of research into smart fuzes that, using a microprocessor and an accelerometer, can actually detect what is happening during penetration and explode at precisely the right time. These fuses are known as hard target smart fuzes (HTSF). See GlobalSecurity.org: ...
transfer: convection, conduction and radiation [source: Cabot Corporation]. Even though aerogel is still quite expensive, the good news is that studies have shown that aerogel insulation used in wall framing and hard-to-insulate areas such as window flashing can save a homeowner up to $750 per...
As the weather warmed up in the Spring of 2022 we started meeting more people on our new dock. One couple across and a few slips down the dock from us had their boat all tented and were working hard to take off their old teak decks and getting ready to push off and head […] ...
