Falcon 9's first stage is able to land within a 30-foot diameter target consistently

The reusability of Falcon 9's first stage rocket has slashed launch costs

Unlike older rockets left to sink in the ocean, the first stage was designed to steer itself back for a controlled landing on a sea-based barge. Refurbishment of these components are half the cost of building new.

SpaceX was built to achieve Elon Musk's vision of making humans an interplanetary species

Learning quickly from early Falcon rocket failures and clashes with vendors and safety regulators, the company has focused on reusability as a first step to reaching Mars and is backed by NASA funding to do so.

SpaceX hopes to use the vehicle for both interplanetary travel and shorter flights around Earth. At 30 feet wide, it allows for more storage and headspace for inhabitants than previous NASA spacecraft.

SpaceX has launched thousands of its Starlink satellites into low-Earth orbit

Every launched batch of satellites contains roughly 60 of the desk-sized gadgets. The batch is released at random into an initial orbit, and it takes time for them to naturally spread out enough before operators begin unfolding their antennae.

A SpaceX spacecraft's battery debris survived reentry and crashed into a Florida home

Although NASA expected the debris to disintegrate after it was jettisoned from the International Space Station in 2024, the flight support component survived reentry. No injuries were reported from the incident.

See the unbuilt rocket design that would have dwarfed the Saturn V

Designed in the early 1960s, the Sea Dragon was a radical concept for an ocean-launched rocket that would have far exceeded the Saturn V in size and payload. The conceptual design was ultimately too risky and impractical to build.

The European Space Agency placed a lander on the surface of a comet in 2014

Launched in 2004, the Rosetta spacecraft performed three flybys of Earth and one of Mars as gravitational slingshots to gain the necessary velocity to successfully place the Philae lander module on comet 67P/Churyumov-Gerasimenko. Philae achieved a soft landing only after bouncing twice from failed deployments of its anchoring harpoons.

Apollo 11’s design relied on shedding parts to reach, land on, and leave the moon

Despite Apollo 11 starting as a 3,000-ton spacecraft, the only part of it that returned to Earth was the small command module, which splashed down in the Pacific Ocean carrying three astronauts and moon rocks.

The Artemis program to bring humans to the moon for the first time since 1972

Using NASA's next-generation megarocket, the Space Launch System, Artemis I will take an uncrewed spacecraft on a 42-day journey around the moon. Subsequent missions plan to land the first woman on the lunar surface.

Explore a timeline of every mission to Mars through 2020

The US has conducted the most missions (23) and has the highest success rate (74%), followed by Russia (18 missions at 5%). The first successful orbiter was Mariner 4, while Viking 1 was the first successful lander.

Orbital spaceflight requires reaching 23 times the speed of sound

After the spacecraft accelerates up to at least 17,500 miles per hour, space tourists can travel in elliptical orbits hundreds of miles above Earth for days or weeks at a time. Suborbital flights instead max out at about 2,200 miles per hour and travel only 50 to 70 miles above Earth's surface for a few minutes.

NASA plans to bring down the ISS at a location farthest from land

Point Nemo is located in the South Pacific Ocean at coordinates 48°52.6'S 123°23.6'W, approximately 2,688 kilometers (1,670 miles) from Ducie Island, Motu Nui, and Maher Island. The location has served as an underwater graveyard for hundreds of satellites and is expected to be harbor the International Space Station in 2030.
