Want to help build humanity’s first Moon base?
We asked @NASAAdmin Jared Isaacman and the
@NASAMoonBase team at MAX POWER "which engineering disciplines will be needed most?"
Here's what they had to say 👇

The protons accelerated inside the Large Hadron Collider travel at 99.9999991% of the speed of light, so fast that they complete the full 27 km ring approximately 11,245 times per second.
In one second, a proton in the LHC travels approximately 300,000 km, roughly the distance from Earth to the Moon.

The Large Hadron Collider at CERN is a 27-kilometre ring buried up to 175 metres underground beneath the French-Swiss border.
Operating conditions:
- Temperature: 1.9 Kelvin (-271 degrees C), colder than outer space
- Magnetic field: 8.3 Tesla, 100,000 times Earth's magnetic field
- Proton speed: 99.9999991% of the speed of light
- Collision energy: up to 13.6 TeV
The protons that collide inside it travel the full 27 km circuit approximately 11,000 times per second.
The LHC is the largest, coldest, and most precisely engineered machine ever built.
It was constructed to ask questions about the first billionths of a second after the Big Bang.

Cuba has installed 1.42 GW of solar capacity across 144 photovoltaic plants and expects to exceed 1.5 GW by the end of 2026.
The legendary 8-bit Zilog Z80 processor, first released back in 1976, remained in production for 48 years and was only discontinued in 2024.
James Watt invented the unit of horsepower in the 1780s not as a scientific measurement but as a sales tool, by timing how much work a mill horse could do in a minute, he created a benchmark his customers already understood, allowing them to calculate exactly how many horses his steam engine would replace and therefore how quickly they would recoup the purchase price.
One horsepower is defined as 33,000 foot-pounds of work per minute, the figure Watt calculated from his horse observations.

Cars make more power in cold weather because the air is denser. The extra oxygen makes the computer inject more fuel to keep the air-fuel ratio right.
Several ways to join pipes and fittings
A ´ton´ can refer to 3 different units of mass.
A metric ton equals 1000kg.
A short ton used in the US equals 2000 lb (907 kg).
A long ton used in the UK equals 2240 lb (1016 kg).
Most robots have motors, batteries, and electronics. This one has muscle.
MIT engineers built a swimming robot thinner than a single sheet of paper, powered by living skeletal muscle cells attached to a flexible polymer frame.
When hit with pulses of light, the cells contract, flapping the robot's fin-like structure and propelling it through water.
No wires. No electronics. No battery inside the robot.

Fill-level indicator for gas cylinders.
It sticks magnetically to common steel propane or butane bottles and uses ultrasound to check whether liquid gas is present at that height. Green means gas is still there; red means the liquid level is already below the sensor. You slide it up and down the bottle to find the fill line.
