Cultivation was conducted in bottles on an orbital shaker (85 rpm) in a greenhouse for two weeks at 26 °C and a light:dark cycle = 16 h:8 h at an intensity of 50 µmol × m−2× s−1. Triplicates from the preculture were transferred without any further treatment to serve ...
Instead, you use its orbital motion. From Newton's version of Kepler's Third Law of Planetary Motion, the orbital speed of an object in circular orbit and a little algebra, you can derive an equation to calculate the amount of mass (Mr) that lies within any circular orbit with a radius...
The satellite system consists of a constellation of 24 satellites in six Earth-centered orbital planes, each with four satellites, orbiting at 13,000 miles (20,000 km) above Earth and traveling at a speed of 8,700 mph (14,000 km/h). While we only need three satellites to produce a lo...
During re-entry into the atmosphere, the capsule will heat up and lose speed. Keep the level indicator aligned with the retrograde marker to let the heat shield take the brunt of the heat. Wait until the capsule's speed drops below 200 m/s, or the parachute sign on the left turns ...
The second factor to consider is that the Earth's orbital speed varies, which is whydays are longer and shorterthroughout the year. The planet moves fastest in early January during perihelion, which is its closest point to the Sun, and moves slowest in early July during aphelion, which is...
The Starship upper stage, meanwhile, will continue powering its way upward and eastward, reaching a top speed close to orbital velocity (which is around 17,000 mph, or 27,400 kph). But the vehicle won't complete a circuit of Earth; roughly 90 minutes after liftoff, it will come down in...
His work involves studying the orbital mechanics for journeys to planetary bodies including Mars. How long does it take to get to Mars & what affects the travel time? The time it takes to get from one celestial body to another depends largely on the energy that one is willing to expend. ...
NASA will live stream the arrival and docking of the Cygnus, which is on its 21st resupply mission to the orbital outpost. Read on to find out how to watch. How to watch NASA will begin its live stream at 1:30 a.m. ET on Tuesday, August 6, on NASA+, NASA Television, the NASA...
microhabitats at a speed that's hard for scientists to compete with. The researchers who discovered this new frog species are hopeful that these new frogs will help bring more conservation efforts into the region so that they, and other species, may live long and prosper for years to come....
