In 1926, Robert Goddard launched Nell — the very first (successful) liquid fuel rocket. But Nell wasn't built like other modern rockets, including a notable lack of casing and an exhaust nozzle suspended above the propellant tanks.

Months before Apollo 8 took humans around the Moon for the first time, two Russian tortoises (plus some other lunar tourists) had already made it back home. This was Zond 5 — the first mission to return to Earth after visiting another...

Unlike most living things, there are species of bacteria that can harness electrons directly and even shuttle them around from place to place like living wires.

Building and launching rockets to learn about other worlds hasn't been great for Earth, but environmental engineers are working on changing that legacy.

Get to know Robert Goddard, one of the original rocket scientists!

Hank demonstrates how to build a hybrid rocket engine in your kitchen!

Yes, fire can burn without oxygen. While oxygen is an important oxidizing agent for combustion, it is not the only one. There are alternative oxidizers such as chlorine, fluorine, and bromine that can also support burning. Furthermore,...

Water is formed as a result of the combustion of hydrogen. In simple words, water is what you get when you burn hydrogen. So, water doesn’t burn because, in a way, it has already burned. You get ashes when you burn paper; but when you’re...

Fireworks combine chemical processes, from combustion to spectroscopy, to create spectacular displays. Discover what happens when the fuse is lit. Chemistry - Reactions - Learning Points. Fireworks involve combustion and exothermic...

Explore the emerging world of space tourism where once only millionaires could venture into orbit, but soon, more accessible options may open up. Discover the experiences of the few who have visited the International Space Station and...

How fun is this chemical traffic light experiment!? Liquid changes colour from green to red and later to yellow. The best part is it is repeatable. Just shake the bottle to start again.



For this experiment you w

Ariane 5 part 4/8: The video explains the importance of the lateral boosters in the Ariane 5 rocket and how they provide the necessary power to overcome Earth's gravity and navigate through the atmosphere. The video also highlights the...

Ariane 5 part 1/8: This video explores the development and history of rockets, focusing on the Ariane 5 launcher and its high-tech payload. It delves into the engineering and ballistic research behind rockets, highlighting the dangers...

Explore the science behind matches and how they spark fire. Learn how components of a match, including red phosphorus, sulfur, ammonium phosphate, and paraffin wax, work together to ignite and sustain a flame. This video also explains...

NASA's Goddard Space Flight Center in Maryland and Kennedy Space Center in Florida joined teams and efforts to test new robotic refueling technologies that could help satellites live longer in space. During the test, a robotic arm...

Explosive experts Dr Jacqueline Akhaven, senior lecturer at Cranfield University, and Research Officer Dr Alex Contini explain the explosive chemical and physcial reactions behind the spectacular fireworks we all love to watch. They do...

This video provides an overview of how stain removers work, explaining the different methods they use to remove or mask stains. It discusses the use of solvents, emulsifiers, enzymes, oxidizers, and whiteners to effectively tackle...

Delhi Blast Probe: Investigators probing the November 10 explosion near Delhi's Red Fort suspect the use of Triacetone Triperoxide (TATP), a highly unstable and powerful explosive. The blast, which killed 13 people, involved a car-borne...

Delhi Blast: Investigators in the Delhi blast case are intensifying their focus on a group dubbed the ‘Doctors of Terror,’ believed to be key operatives behind the attack. This group is suspected of orchestrating violent acts and...

Oct. 31 -- A spacecraft for Sir Richard Bransons Virgin Galactic tourism operator crashed during a test flight in Californias Mojave Desert, and CNBC reported that one of two pilots was killed. Former Astronaut Leroy Chiao and...
