miles per hour
(39,400 kph) is the speed at which Orion entered the Earth’s atmosphere on its return.
(900 kg) of weight was saved by making the rocket boosters single-use instead of reusable. The Space Launch System (SLS) did not carry the fuel or the propulsion system it would have needed to haul it back during its return to Earth.
after liftoff, the rocket was 2,400 miles (3,860 km) above Earth. The remaining upper stage of the Space Launch System detached and Orion completed the trip to the moon without the rocket.
hitched a ride on the rocket. These small satellites aimed to carry out their own science and technology investigations but at least four failed.
(409,150 liters) of liquid hydrogen and liquid oxygen burned every minute for eight minutes by four RS-25 engines that were part of the Space Launch System.
made up Orion’s parachute system. They deployed in precise sequence to slow the spacecraft from 324 mph (520 kph) to a landing speed of 17 mph (27 kph), so it was ready for splashdown in the Pacific Ocean.
(432,210 km) was the distance the Artemis I mission traveled from Earth, far beyond the moon.
(2,760°C) is nearly the temperature that Orion’s heat shield endured as it returned through Earth’s atmosphere -- that’s half as hot as the surface of the sun.
(900,000+ kg) of solid propellant (PBAN, ammonium perchlorate and aluminum powder) filled the twin rocket boosters alone. And it was all used up within two minutes.
(4 million kg) was the thrust the Space Launch System produced to leave Earth’s atmosphere. That’s equal to the combined thrust of 126 of the largest civil aircraft, the Airbus A380.
(98 m) was the height of the Artemis I rocket stack -- a little taller than the Statue of Liberty.
(2.1 million km) was the total distance that the Artemis I mission covered.
(2.6 million kg) was the weight of the Space Launch System at liftoff. That's the weight of eight fully loaded 747 jumbo jets.
were onboard the uncrewed mission to test systems in a spaceflight environment.
(161 km) was the altitude the Space Launch System reached eight minutes after liftoff before its core stage separated and fell into the Pacific Ocean, landing east of Hawaii.
is the duration of the Artemis I mission to the moon and back.
blasted the Space Launch System out of Earth’s gravitational pull, only to detach two minutes after liftoff. The boosters then fell into the Atlantic Ocean, north of the Bahamas.
is how long it took to get from the Earth to the moon.
was all it took for the rocket to lift off and go into orbit.
