What is the difference between suborbital and orbital spaceflight?

• Suborbital flight reaches space (typically defined as above 80-100 km altitude) but doesn't achieve the velocity needed to orbit Earth. The vehicle follows a parabolic trajectory, returning to Earth after a brief period in space. This requires much less energy than orbital flight, where a vehicle must reach approximately 28,000 km/h (17,500 mph) to maintain orbit. Virgin Galactic and Blue Origin's current passenger flights are suborbital, while SpaceX's Dragon capsule achieves orbit.

How do reusable rockets work?

• Reusable rockets preserve their first stage (and sometimes other components) by controlling their descent back to Earth after launch, rather than discarding them to burn up in the atmosphere or sink in oceans. SpaceX's Falcon 9 uses grid fins for steering, engine burns to slow its descent, and deployable landing legs to touch down on land or drone ships at sea. Blue Origin's New Shepard uses a propulsive landing system with its BE-3 engine for vertical precision landing.

What fuels do these rockets use?

The companies use different propellants:

• SpaceX's Falcon rockets use refined kerosene (RP-1) and liquid oxygen for the first stage, while their newer Raptor engines for Starship use liquid methane and liquid oxygen.

• Blue Origin's New Shepard uses liquid hydrogen and liquid oxygen, while their BE-4 engine for New Glenn uses liquefied natural gas (primarily methane) and liquid oxygen.

• Virgin Galactic's SpaceShipTwo uses a hybrid rocket motor with solid hydroxyl-terminated polybutadiene (HTPB) fuel and liquid nitrous oxide oxidizer.

How do these companies make money?

Revenue sources vary by company:

• SpaceX generates revenue primarily through satellite launch services for commercial and government customers, Starlink internet service subscriptions, and NASA contracts for cargo and crew transportation.

• Blue Origin earns revenue from suborbital tourism, government research payloads, engine sales to other aerospace companies, and NASA development contracts.

• Virgin Galactic focuses on revenue from space tourism tickets and has potential future income from research flights and partnerships.

Are these companies profitable?

• As a private company, SpaceX doesn't disclose detailed financials, but reports suggest it has achieved profitability on certain business lines. Blue Origin has been primarily funded by Jeff Bezos and isn't structured for short-term profitability. Virgin Galactic, being publicly traded, has reported losses as it scales up operations, focusing on long-term growth rather than immediate profitability.

What is the space economy, and how big is it?

• The space economy encompasses all activities and resources involved in exploring, researching, utilizing, and managing space. This includes hardware manufacturing, launch services, satellite operations, ground equipment, and various space-enabled services like telecommunications, Earth observation, and navigation. Industry analysts valued the global space economy at approximately $450-500 billion in 2023, with projections to reach $1 trillion or more by 2040.

What environmental impact do rocket launches have?

Rocket launches produce various environmental impacts, including:

• Carbon emissions from fuel combustion (particularly kerosene-based fuels)

• High-altitude emissions that may affect the ozone layer and contribute to climate forcing

• Local noise pollution around launch sites

• Manufacturing impacts from resource extraction and industrial processes Different rocket fuels have varying environmental footprints, with hydrogen producing primarily water vapor but methane and kerosene producing carbon dioxide.

Is space debris from these companies a serious problem?

• Space debris is a growing concern as launch activities increase. SpaceX's Starlink constellation has raised particular questions about orbital congestion, though the company has implemented debris mitigation measures including lower operational orbits, automated collision avoidance systems, and end-of-life disposal plans. All three companies support responsible space operations and work within regulatory frameworks to minimize debris creation.

Should billionaires be spending money on space when there are problems on Earth?

• This question involves personal values and perspectives. Proponents argue that private space investment advances technologies that benefit life on Earth (satellite communications, climate monitoring, new materials), creates high-skilled jobs, and ensures humanity's long-term survival through space capabilities. Critics contend that these resources could more directly address immediate human needs like poverty, healthcare, and climate change. Most space companies point to the practical benefits their technologies provide for Earth-based challenges.

Will space travel become affordable for average people?

• While current space tourism offerings remain limited to wealthy individuals (with prices from $250,000 to several million dollars), the industry aims to gradually reduce costs through reusable technology, scale, and competition. Historical trends in air travel suggest space tourism prices could decrease significantly over decades, though suborbital experiences may become accessible to upper-middle-class consumers faster than orbital trips. Companies frequently compare early space tourism to the early days of aviation, which evolved from exclusive luxury to mass transportation.

What are the next major milestones for these companies?

Key upcoming milestones include:

• SpaceX: Orbital tests of the full Starship system, expansion of Starlink service, and preparation for potential Moon and Mars missions

• Blue Origin: First orbital launch of New Glenn, expanded New Shepard operations, and development of lunar landing capabilities

• Virgin Galactic: Scaling commercial operations with additional spacecraft, reducing turnaround time between flights, and potentially developing point-to-point transportation capabilities

Will these companies replace government space programs?

• Rather than replacement, the industry is moving toward complementary roles and partnerships. Private companies increasingly handle routine transportation and commercial services, allowing government agencies to focus on scientific research, exploration, and regulatory oversight. This public-private partnership model has become the standard approach for modern space programs globally, with NASA serving as both customer and partner to companies like SpaceX while maintaining its own deep space exploration initiatives.

SpaceX, Blue Origin, and Virgin Galactic represent three distinct approaches to private space enterprise, each contributing uniquely to the emerging space economy. SpaceX has focused on rapid innovation and orbital capabilities with Mars as its ultimate goal. Blue Origin has taken a more methodical approach toward building space infrastructure for the long term.
