Worlds Lightest Solid!


Aerogels are the worlds lightest (least dense) solids. They are also excellent thermal insulators and have been used in numerous Mars missions and the Stardust comet particle-return mission. The focus of this video is silica aerogels, though graphene aerogels are now technically the lightest.

At one point Dr. Steven Jones literally held the Guinness World Record for making the lightest aerogel and therefore lightest solid. If youre interested in learning more about aerogels, let me know in the comments as there is a potential trilogy in the works…

Huge thanks to Dr. Stephen Steiner and the crew at Aerogel Technologies. To find out more or buy your own aerogel sample, check out: www.aerogeltechnologies.com/

Thanks to Dr. Steven Jones and Dr. Mihail Petkov at NASAs Jet Propulsion Laboratory

Building a Medieval House | 10 Day Bushcraft Shelter Build


Building a medieval house in the woods, a 10 day bushcraft shelter. This is a full build video of the anglo saxon house with thatch roof that we built using simple hand tools. This medieval-era bushcraft camp was inspired by the anglo saxon «pit house». The saxons occupied Britain from the 5th to the 11th century. Many of their houses were built by digging a pit in the ground which would not only help to keep a consistent temperature in their homes throughout the year, but it would also mean that they needed less building materials to build the house upwards. We used simple hand tools: axe, saw, knife, pick axe, hand auger and drawknife to build this tiny house in the forest. I built this with my Dad in 10 days. See below for individual episodes of the Saxon House series where we talk about what we are doing and why.

«Луноход» — назад в будущее


В конце февраля 1971 года была завершена основная трехмесячная программа работы «Лунохода». Анализ бортовых систем показал возможность продолжения активной работы аппарата. Поэтому для «Лунохода» составили дополнительную полугодовую программу. «Луноход-1» проехал по Луне 11 километров, передал на Землю 20 тысяч снимков лунного рельефа. Надежность «Лунохода-1» позволила работать на Луне почти год и в три раза превысить программу исследований.

Falcon Heavy. Большим амбициям - большую ракету


SpaceX Falcon Heavy — сверхтяжелая ракета-носитель, разработанная фирмой SpaceX в конце 2010-хх.
Имея теоретическую возможность выводить на низкую околоземную орбиту полезные нагрузки массой до 63 тонн, является самым мощным носителем из ныне эксплуатируемых и уступает только ракетам Saturn V и Энергия.
Первый испытательный пуск был выполнен 6 февраля 2018 года, в качестве имитатора полезной нагрузки был использован автомобиль Tesla Roadster.
