Things are looking up again in low Earth orbit. Between 180 and 2,000 kilometers, this region of space has hosted a majority of human spaceflights and includes the International Space Station (ISS). Despite the failure last month of a SpaceX cargo rocket bound for the station, NASA continues its commitment to commercial space missions. As such, the agency announced the four astronauts chosen to fly on the first manned U.S. flights. These missions will be the first in four years to launch American astronauts from U.S. soil, in a bid to eventually end NASA’s reliance on Russia for access to orbit. “It’s a milestone announcement,” says space history expert Robert Pearlman. “It sends the message that these flights are closer than the general public might think.” NASA aims to send the first commercial crew missions to the ISS in late 2017 but further mishaps or technical hurdles could imperil that timeline.
The chosen four—Robert Behnken, Eric Boe, Douglas Hurley and Sunita Williams—are decorated military veterans and pilots turned astronauts. Combined, they have spent over a year in space, orbiting Earth hundreds of times. Williams holds the record for total cumulative spacewalk time by a female astronaut, chalking up 50 hours and 40 minutes. “These distinguished, veteran astronauts are blazing a new trail—a trail that will one day land them in the history books and Americans on the surface of Mars,” NASA Administrator Charles Bolden said in a statement.
NASA has partnered with two companies, SpaceX and Boeing, to build spacecraft for ISS resupply and manned commercial missions. Aviation titan Boeing has a $4.2-billion deal with NASA; Elon Musk’s SpaceX holds a separate $2.6-billion contract. Each company is guaranteed two service flights, with the possibility of winning any number of four currently unclaimed future flights, according to Boeing spokesperson Kelly Kaplan.
The June SpaceX accident has complicated the company’s image as the front-runner of the commercial space race. Although the Falcon 9 rocket and Dragon capsule involved in the June 28 failure were intended only for cargo, SpaceX intends to use similar spacecraft on manned missions. If the rocket had been equipped with an escape system, astronauts would likely survive the crash, Pearlman says. But even routine mission aborts place astronauts in harrowing conditions. Both Boeing and SpaceX plan to test in-flight aborts in early 2017.
Flying space station crews on commercial flights mark a dramatic departure from tradition. This move enables NASA to use its own funds and resources to focus on designing spacecraft for more challenging deep-space missions—meaning expeditions beyond Earth orbit, such as to the moon and asteroids, and eventually Mars. This year has been marked by a string of mishaps: Three of the four types of unmanned spacecraft that currently carry cargo to the station failed to reach their destination. (One was the June SpaceX accident; a Russian Progress vehicle and a commercial Orbital ATK capsule also suffered recent failures. On July 5, however, .
NASA’s reliance on Russian Soyuz rockets to shuttle U.S. astronauts to the space station has a per-seat price tag of around $70.7 million, a fee that has been rising with inflation, Pearlman says. Boeing and SpaceX’s vehicles would reduce that cost to roughly $58 million and redirect that money to U.S companies. “It’s really critical for the United States to regain its own launch capability,” Williams, one of the chosen astronauts, . “That’s going to allow us to further our abilities and advance our technologies to build the next generation of spacecraft for the next generation of space explorers.”
Meanwhile, NASA’s funding faces dangers of its own. In Congress the already dwindling support for NASA may be in jeopardy. One of the agency’s staunchest defenders, Florida Sen. Bill Nelson (D), who flew on the space shuttle Columbia in 1986, . Nelson is the ranking member of the committee that oversees NASA. “Nelson kept the NASA budget alive and running,” Handberg says. “There’s no one else driving to do that.” The 2015 NASA budgetary request totaled to $17.4 billion, a cut of just over $250 million dollars from 2014. As the money keeps slipping, launch dates do, too. In December 2014 NASA’s projected 2017 test flight date for its deep-space Space Launch System rocket and Orion spacecraft , thanks to uncertainty in funding, among other problems.
