Print Collector/Getty Images At 8: 44 a.m. on February 1, 2003, Space Shuttle Columbia re-entered Earth’s atmosphere at around 400,000 feet. Over the next eight minutes, Columbia descended 150,000 feet at Mach 24.1, causing extreme thermal heating and triggering the left wing sensors, which recorded greater strain than in previous Columbia re-entries.  As the orbiter […]

When developing projects that will require portability, and connectivity, your first instinct is to grab a Raspberry Pi. And why not? This single-board computer (SBC), which has become especially popular among makers and hobbyists, not only offers various features and versatile use cases, but is also affordable, easily accessible, and designed to be as user

Any unit capable of cooling an entire home or business during the heat of summer will require an investment

The great thing about Raspberry Pis, compared to Arduinos, is that you don’t have to scour Amazon or your local electronics shop for a high-quality power supply to drive your board. Raspberry Pi offers official power supplies that you can easily buy alongside your single-board computer (SBC) of choice. However, not every Raspberry Pi project

M.J.J. de Vaan/Shutterstock We’ve come a long way since the age of propellor-based aviation. Sure, there are still plenty of single turboprop engine airplanes, but these days most planes — especially the big ones — require more thrust. Today, commercial craft generally use jet engines, and one might assume that the more engines a plane has,

Aerial-motion/Shutterstock If you take a chunk of steel and throw it in some water, you may notice it sinks pretty quickly. So how does an aircraft carrier, which is made from around 100,000 tons of steel, stay afloat? The simple answer is, it uses the same principles as any other boat to stay above the

Michaelbwatkins/Getty Images Aircraft carriers are a marvelous thing — massive sea fortresses heavier than most vehicles on land that manage to stay afloat while carrying multiple aircraft. Of course, they have their limits, mostly stemming from the fact that carriers’ landing strips are on average just 300 feet long. This means that aircraft that fly to and from

Global Images Ukraine/Getty Images Since Russia invaded Ukraine in 2022, various nations have supplied the beleaguered nation with all manner of arms and armaments. Most of the media’s attention has been on American, German, and British tanks, anti-aircraft weapons, and artillery. One vehicle that hasn’t received as much attention is arguably one of the most

The McDonnell Douglas F-15 Eagle, better known simply as the F-15, is a legend of the skies. Sleek, fast, and boasting an array of weapons, the F-15 has been a staple of the United States Air Force’s arsenal in some form since the 1970s. While the military minds who dedicated their professional lives to making these

Whether it was the Teutonic Knights on frozen Lake Peipus in 1242 A.D., the French fighting the Russians during a blizzard at Eylau in 1807, or the Western Front freezing during the winter of 1916 and 1917 in WWI, many armies have fought in near-Arctic conditions without the right training or equipment. As a result,

Narinuk Images/Getty Images While America’s massive fleet of aircraft carriers is difficult to sink, they are sadly not unsinkable. The title of this article refers to Midway Atoll as an «Unsinkable Aircraft Carrier,» but as many know, Midway isn’t a ship — it’s an island. The term «Unsinkable Aircraft Carrier» refers to any island that

Though the country is steeped in tradition and pride, it’s still given the world simple practicality when needed. Furthermore, the region has utilized its resources and is among the
