They were to dock at the orbiting outpost six hours later, but the booster suffered a failure minutes after the launch. The spacecraft was able to separate with the booster and return to earth using the backup ballistic descent mode.
Rescue crews then raced to the scene to retrieve them with reports of paratroopers parachuting to their landing spot. NASA also said in a statement that "NASA Administrator Jim Bridenstine and the NASA team are monitoring the situation carefully", and that a "thorough investigation" will be conducted.
After the booster failed, Ovchinin and Hague were forced to make a ballistic descent, coming back to the ground at a sharper angle than normal and causing higher gravitational forces on their bodies.
"Spaceflight is hard. And we must keep trying for the benefit of humankind", ESA astronaut Alexander Gerst tweeted from aboard the space station as he watched and photographed the launch from space. The space station and its crew depend heavily on missions supported by the rocket.
"The crew landed", Dmitry Rogozin, director of the Russian space agency Roscosmos, said on Twitter.
Russia's Investigative Committee said a criminal probe would seek to determine whether safety regulations had been violated during construction, causing major damage.
It was to be Hague's first flight to the station, launching at 3:40 a.m. Thursday from Kazakhstan's Baikonur Cosmodrome.

NASA coordinated a private event at Peabody's Coneburg Inn exclusively for Hague's extended family, sending astronaut Victor Glover to be a personal envoy to the family there. Helicopters have already dispatched to look for the Soyuz space capsule, she said.
The current iteration of the manned Soyuz booster, the Soyuz-FG, had until today boasted a 100 percent success rate. Roscosmos sent more than 70 rocket engines back to production lines to replace faulty components.
The Expedition 57 crew members are working on hundreds of experiments in biology, biotechnology, physical science and Earth science, according to NASA.
