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

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

SpaceX's Falcon 9 rocket releases its reusable first stage hundreds of miles above the Earth's surface as it travels thousands of mile per hour. The stage often then lands on an autonomous ocean drone in the middle of the sea.

The first version, called Starhopper, was named with the vision of developing rocket stages that could safely land after use, enabling reusability to cut costs. The endeavor was an enormous engineering challenge that required years of testing.

A primer on SpaceX's primary rockets and spacecraft

SpaceX has developed several lines of rockets, from its workhorse Falcon 9 to the visionary Super Heavy rocket of the company's Starship designed for massive payloads. Each iteration costs millions of dollars and came with scientific and economic challenges and several are no longer in development. Learn more about the company's roster of rockets and craft here.

A lunar 'satellite catapult' revives a 50-year-old idea for launching rockets

Elon Musk has proposed building a mass driver on the moon to fling satellites into space, exploiting low gravity to cut fuel and costs. The concept dates to 1970s space-settlement studies, highlighting how older industry ideas are resurfacing amid today's AI and space-infrastructure race.

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.

Commercializing space debris removal may follow the commercialization of launches

Active debris removal is likely to focus on larger derelict objects, which are more easily identified and yield better financial returns. One actively researched possibility involves using netting to capture derelict objects before towing them into a controlled descent into an ocean.

Find out how decommissioned oil rigs can be repurposed into artificial reefs

A 2014 paper analyzing drilling structures found many had become nursery habitats for fish, corals, sponges, and other invertebrates in the decades since their installation. Oil companies responsible for bringing these rigs to shore to salvage them can more affordably transport only the oil rig's deck on a barge, leaving the remaining rig to maintain the established biodiversity.

Construction of small, affordable starter homes has decreased 75% since the 1970s

Rising costs aren’t the only thing stopping first-time homebuyers from buying real estate—only 9% of recent new construction is for starter homes. The majority of new housing construction focuses on higher-end buyers due to the increased cost of land, labor, and resources.

SpaceX's S-1 or 'prospectus' revealed many previously unknown details about the company, including its unprofitability despite doing $18.7B in revenue in 2025, exactly how many voting shares Elon Musk will have in the company (roughly 85%), and more.

Firefly Blue Ghost lands private craft on the moon

On March 2, 2025, Firefly Aerospace landed its Blue Ghost craft on the Moon. The private company then operated the craft for two weeks, conducting surface operations and becoming the first private space company to have a fully successful mission on the Moon. This short video captures pristine, dramatic footage of the mission's successful touchdown.

Supersonic parachutes have allowed rovers to safely land on Mars' surface
