Does Space X Falcon Actually Saves Money
On 27 May, NASA volition launch people into infinite from U.S. soil for the first time since 2011, when the space shuttle Atlantis roared aloft on its final voyage. This time, astronauts will exist riding to the International Space Station (ISS) not on a NASA rocket, only aboard vehicles bought from the individual infinite visitor SpaceX: the Dragon 2 sheathing atop a Falcon 9 rocket.
The occasion marks nevertheless another milestone for the individual California company, which over the past decade has gone from underdog to dominator. SpaceX now handles about two-thirds of NASA's launches, including many research payloads, with flights as cheap equally $62 one thousand thousand, roughly two-thirds the toll of a rocket from United Launch Alliance, a competitor. SpaceX's goals are not limited to depression-Globe orbit: Last calendar month information technology was selected to pattern a Moon lander, and it is steadily testing a huge heavy-lift rocket, called Starship, that could carry people to Mars.
Researchers encounter both benefits and risks in the company'south increasing ability. It has lowered the cost of spaceflight through innovations such every bit reusable stages and fairings, saving NASA money. With its outsize capacity, Starship could cheaply put large telescopes in orbit and heavy scientific discipline experiments on moons and planets. Yet SpaceX, with a fast-and-loose Silicon Valley mindset, has overlooked the potential for its technologies to contaminate night skies and pristine planets. Some worry the company, led by brazen billionaire Elon Musk, could jeopardize NASA's long-standing culture of safe. "NASA tries to model everything to the nth degree," says David Todd, an analyst at Seradata, which tracks launches and satellites. "SpaceX works on the ground of 'test it until it breaks.'"
Between 2006 and 2008, the first three flights of its Falcon 1 rocket ended in failure. SpaceX pivoted to a larger Falcon ix rocket in 2010, and began to evangelize cargo to the ISS for NASA 2 years afterward. Since then, its ambitions have grown. "A lot of other space companies are trying to win contracts," says Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Centre for Astrophysics (CfA). "SpaceX is trying to get to Mars. It turns out that having a goal tin can be economically successful."
Going upward
The upcoming crewed flight could readapt the Russian rockets NASA has hired—at a hefty price—to carry humans to the ISS since 2011. Cheaper, more than frequent flights could improve the biomedical and physical science experiments aboard the station, says industry analyst Laura Forczyk, owner of the infinite consulting firm Astralytical. "More people equals more research," she says.
SpaceX has additional NASA science in other ways, delivering the climate-observing Jason-3 satellite and the planet-seeking Transiting Exoplanet Survey Satellite to orbit. In 2022, it is set to launch the Psyche mission to a metallic asteroid, in the first NASA launch of a Falcon Heavy, which sits between the Falcon 9 and Starship in its propulsive power.
Just it's the company'south upcoming Starship that has designers of science missions salivating. SpaceX has not appear a date for an countdown flight, but has built six prototypes at a stride of nearly i per month. (Iii have been accidentally destroyed in testing.) The steel blend spacecraft and its superheavy booster stand up 120 meters tall, towering over the Saturn Five that carried people to the Moon. Terminal year, Musk said full reusability and thrifty use of propellant would drop the price of each Starship launch to $2 meg. Todd suggests $10 1000000 per flight might be more realistic.
The rocket'due south 9-meter-diameter cargo concord could easily adjust giant celestial observatories, such as the proposed Habitable Exoplanet Observatory, which would directly image distant planets. 1 reason for the endless delays afflicting the James Webb Infinite Telescope, the successor to the Hubble Space Telescope, has been the need to fold up its segmented 6.5-meter mirror to fit aboard a European Ariane v rocket, says CfA astrophysicist Martin Elvis.
A feasible Starship could also create political pressure to scupper the Infinite Launch Organization (SLS), the NASA-developed heavy-lift rocket that is supposed to ability the agency back to the Moon and on to Mars. In Dec 2019, NASA Administrator Jim Bridenstine said it could cost $900 million per launch—if it e'er launches. Its debut has repeatedly slipped, and is now expected at the end of 2021. But 1 or ii years subsequently, it is supposed to carry astronauts to lunar orbit, only McDowell doubts it volition remain in production for very long. "If Starship works, that's the decease knell for SLS," he says. SpaceX, along with private companies Blueish Origin and Dynetics, was called in Apr to design lunar landers for astronauts and supplies.
SpaceX put forth the Starship spacecraft every bit its lander, which could launch atop its ain booster or a NASA-congenital one. There would exist plenty of room for scientists to piggyback experiments, such as a radio telescope to peer back to the earliest era of milky way formation from the Moon'south far side, says Steve Clarke, NASA's deputy acquaintance administrator for scientific exploration.
Yet SpaceX'southward haste to go big could too cause trouble for scientists. The Starship lander will be much heavier than the spindly lunar module of the Apollo missions. The grit and rocks information technology kicks upwardly could rise into lunar orbit, creating an interfering brume for other landers and threatening satellites and outposts, Elvis says. The visitor's long-standing goal to colonize Mars has the potential to contaminate the planet with terrestrial microbes that could derange researchers, he adds. SpaceX did non respond to requests for comment for this commodity.
In recent months, the company has angry the ire of astronomers with the launch of hundreds of Starlink satellites, which are intended to evangelize high-speed internet to remote areas. From the ground, the satellites appear surprisingly bright because of their low orbits, and they take left disruptive trails on the cameras of survey telescopes. "I don't think they intended to screw up people's skies," says Megan Donahue, president of the American Astronomical Society. "Information technology was just because nobody asked that question of them."
SpaceX is trying to mitigate the event. Some satellites in the next batch, set to launch soon afterward the crewed test, will be blackened and equipped with visors that block sunlight. Donahue praises the company for working with researchers to address the problems. "We're all into scientific discipline," she says.
But the episode has reminded space scientists non to underestimate SpaceX's potential impacts on their fields. Although Musk is often too bullish about the time scales for his projects, McDowell says, he tends to realize his dreams in the cease. "[Musk] has strengths and weaknesses. His overoptimism is kind of both."

The story has likewise been changed to more than accurately compare the price of a Falcon 9 and to clarify the nature of SpaceX's lunar lander award, the description of Starship, and the source of a cost gauge for the SLS.
