Soyuz crew members Sergey Volkov of Roscosmos, Andreas Mogensen of ESA (European Space Agency) and Aidyn Aimbetov of the Kazakh Space Agency joined their Expedition 44 crewmates when the hatches between the Soyuz TMA-18M spacecraft and the International Space Station officially opened at 6:15 a.m. EDT. Expedition 44 Commander Gennady Padalka of Roscosmos, as well as Flight Engineers Scott Kelly and Kjell Lindgren of NASA, Flight Engineers Oleg Kononenko and Mikhail Kornienko of Roscosmos, and Kimiya Yui of the Japan Aerospace Exploration Agency (JAXA) welcomed the new crew members aboard their orbital home, marking the first time since 2013 that nine people have been aboard the orbiting laboratory.

Meet the CST-100 Starliner, the newly unveiled name of Boeing’s commercial crew transportation spacecraft. It's been designed with a focus on automated flight, reliable operation and frequent flights carrying NASA astronauts to the space station. It also may take paying customers to the awe-inspiring heights of low-Earth orbit and the unique sensation of sustained weightlessness. NASA last year awarded contracts to Boeing and SpaceX to each develop systems that will safely and cost effectively transport astronauts to the International Space Station from the United States.
If you liked the first historic images of Pluto from NASA’s New Horizons spacecraft, you’ll love what’s to come. Seven weeks after New Horizons sped past the Pluto system to study Pluto and its moons – previously unexplored worlds – the mission team will begin intensive downlinking of the tens of gigabits of data the spacecraft collected and stored on its digital recorders. The process moves into high gear on Saturday, Sept. 5, with the entire downlink taking about one year to complete.
Hopping, tumbling and flipping over are not typical maneuvers you would expect from a spacecraft exploring other worlds. Traditional Mars rovers, for example, roll around on wheels, and they can't operate upside-down. But on a small body, such as an asteroid or a comet, the low-gravity conditions and rough surfaces make traditional driving all the more hazardous.

In a survey of NASA's Hubble Space Telescope images of 2,753 young, blue star clusters in the neighboring Andromeda galaxy (M31), astronomers have found that M31 and our own galaxy have a similar percentage of newborn stars based on mass. By nailing down what percentage of stars have a particular mass within a cluster, or the Initial Mass Function (IMF), scientists can better interpret the light from distant galaxies and understand the formation history of stars in our universe.
The Kosmos-1315 satellite, which was sent into space in 1981, has ended its ballistic existence, the Russian Defense Ministry told Interfax-AVN on Sept.1 with reference to specialists from the Aerospace Forces' main space monitoring center, which tracked the satellite's operations.
When the sun set on Saturn's rings in August 2009, scientists on NASA's Cassini mission were watching closely. It was the equinox -- one of two times in the Saturnian year when the sun illuminates the planet's enormous ring system edge-on. The event provided an extraordinary opportunity for the orbiting Cassini spacecraft to observe short-lived changes in the rings that reveal details about their nature.
