Jeff Williams, Alexey Ovchinin, Oleg Skripochka have returned to Earth [cbsnews.com] from the International Space Station:
Less than a week after winding up a successful spacewalk, outgoing space station commander Jeff Williams, America's most experienced astronaut, joined two Russian cosmonauts for a fiery return to Earth Tuesday, closing out a 172-day mission with an on-target landing in Kazakhstan.
[...] The four-minute 41-second burn slowed the ship by 286 mph, just enough to drop the far side of the orbit deep into Earth's atmosphere. After a 25-minute free fall to just above the top of the discernible atmosphere, the three modules making up the Soyuz TMA-20M spacecraft separated. A few moments after that, the central crew cabin, the only module protected by a heat shield, slammed into the atmosphere at an altitude of 62 miles and a velocity of some 17,000 mph. Using atmospheric friction to slow down, the descent module's main parachute deployed at an altitude of a little less than seven miles and the spacecraft settled to the steppe of Kazakhstan.
[...] For Williams, the end of the mission marked a personal milestone. On Aug. 20, he surpassed the U.S. record for most cumulative time in space [cbsnews.com] -- 520 days -- that was set earlier this year by astronaut Scott Kelly [cbsnews.com] at the end of his nearly yearlong mission. With landing Tuesday, Williams' mark will stand at 534 days aloft over four missions, moving him up to 14th on the list of most experienced spacemen. The overall record is held by Gennady Padalka, who has logged 878 days in space over five missions.
