International Space Station Partners Adjust Spacecraft Schedule

Soyuz launch

NASA and its international partners agreed Tuesday to set a new schedule for spacecraft traffic to and from the International Space Station.

The partner agencies agreed to adjust the schedule after hearing the Russian Federal Space Agency’s (Roscosmos) preliminary findings on the recent loss of the Progress 59 cargo craft. The exact dates have not yet been established, but will be announced in the coming weeks. Roscosmos expects to provide an update about the Progress 59 investigation on Friday, May 22.

NASA Research Reveals Europa’s Mystery Dark Material Could Be Sea Salt

Credits: NASA/JPL-Caltech

NASA laboratory experiments suggest the dark material coating some geological features of Jupiter’s moon Europa is likely sea salt from a subsurface ocean, discolored by exposure to radiation. The presence of sea salt on Europa’s surface suggests the ocean is interacting with its rocky seafloor — an important consideration in determining whether the icy moon could support life.

NASA Completes MESSENGER Mission with Expected Impact on Mercury’s Surface

MESSENGER_-_spacecraft_at_mercury_-_atmercury_lg

A NASA planetary exploration mission came to a planned, but nonetheless dramatic, end Thursday when it slammed into Mercury’s surface at about 8,750 mph and created a new crater on the planet’s surface.

Mission controllers at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland, have confirmed NASA’s MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft impacted the surface of Mercury, as anticipated, at 3:26 p.m. EDT.

Mission control confirmed end of operations just a few minutes later, at 3:40 p.m., when no signal was detected by NASA’s Deep Space Network (DSN) station in Goldstone, California, at the time the spacecraft would have emerged from behind the planet...

Russian Resupply Ship Experiencing Difficulties; International Space Station, Crew are Fine

iss042e015787

The six crew members of the International Space Station (ISS) are safe and continuing regular operations with sufficient supplies as Russian flight controllers plan for another attempt to communicate with a cargo resupply spacecraft bound for the station. The next attempt to link with the spacecraft comes at 8:50 p.m. EDT Tuesday.

The ISS Progress 59 cargo spacecraft launched successfully from the Baikonur Cosmodrome at 3:09 a.m. (1:09 p.m. in Kazakhstan) Tuesday on a Soyuz rocket bound for the space station. Right after it separated from the Soyuz booster’s third stage, an unspecified problem prevented Russian flight controllers from determining whether navigational antennas had deployed and whether fuel system manifolds had pressurized as planned.

Spacecraft Data Suggest Saturn Moon’s Ocean May Harbor Hydrothermal Activity

Image Credit: NASA/JPL

NASA’s Cassini spacecraft has provided scientists the first clear evidence that Saturn’s moon Enceladus exhibits signs of present-day hydrothermal activity which may resemble that seen in the deep oceans on Earth. The implications of such activity on a world other than our planet open up unprecedented scientific possibilities.

“These findings add to the possibility that Enceladus, which contains a subsurface ocean and displays remarkable geologic activity, could contain environments suitable for living organisms,” said John Grunsfeld astronaut and associate administrator of NASA’s Science Mission Directorate in Washington...

New Crew Launches to Space Station to Continue Scientific Research

Baikonour

NASA astronaut Butch Wilmore and Russian cosmonauts Alexander Samokutyaev and Elena Serova joined their Expedition 41 crewmates when the hatches between the Soyuz TMA-14M spacecraft and the International Space Station officially opened at 1:06 a.m. EDT. Expedition 41 Commander Max Suraev of the Russian Federal Space Agency and Flight Engineers Reid Wiseman of NASA and Alexander Gerst of the European Space Agency, who arrived at the station in May, welcomed the new crew members aboard their orbital home.

Fourth Dragon for Commercial Resupply Services Arrives at Station

Dragon Approach

The Dragon commercial cargo craft has completed a two day trip to the International Space Station after launching early Sunday morning. NASA astronaut Reid Wiseman and European Space Agency astronaut Alexander Gerst were at the controls of the robotics workstation in the Cupola when the Canadarm2 grappled Dragon at 6:52 a.m. EDT Tuesday. Dragon will spend the next four weeks attached to the Harmony node as the Expedition 41 trio unloads 4,885 pounds of (2,216 kg) crew supplies, hardware, experiments, computer gear and spacewalk equipment. This is the fourth SpaceX mission for NASA’s Commercial Resupply Services contract, designated SpaceX CRS-4, with eight more missions slated to deliver a minimum of 20 metric tons to the station.

SpaceX Dragon launches to the ISS

Dragon v2 builds on SpaceX’s track record of successfully delivering critical cargo and science experiments to the space station for NASA. The Dragon spacecraft currently resupplies the space station under a $1.6 billion Cargo Resupply Services contract with NASA.

NASA Television coverage of the September 20 launch of the SpaceX Dragon cargo craft on the company’s CRS-4 mission to the International Space Station. The spacecraft’s 2.5 tons of supplies, science experiments, and technology demonstrations includes critical materials to support 255 science and research investigations that will occur onboard the station.

Hubble Helps Find Smallest Known Galaxy Containing a Supermassive Black Hole

Artist's View of M60-UCD1 Black Hole

Astronomers using data from NASA’s Hubble Space Telescope and ground observation have found an unlikely object in an improbable place — a monster black hole lurking inside one of the tiniest galaxies ever known. The black hole is five times the mass of the one at the center of our Milky Way galaxy. It is inside one of the densest galaxies known to date — the M60-UCD1 dwarf galaxy that crams 140 million stars within a diameter of about 300 light-years, which is only 1/500th of our galaxy’s diameter.

NASA Mars Spacecraft Ready for Orbit Insertion

This image shows an artist concept of NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) mission. MAVEN is part of NASA's Mars Scout program, funded by NASA Headquarters and managed by NASA's Goddard Space Flight Center in Greenbelt, Maryland. Launched in November 2013, the mission will explore the Red Planet’s upper atmosphere, ionosphere and interactions with the sun and solar wind.
On Sept. 21, 2014, MAVEN will enter orbit around Mars, completing an interplanetary journey of 10 months and 442 million miles (711 million kilometers).
Scientists will use MAVEN data to determine the role that loss of volatiles from the Mars atmosphere to space has played through time, giving insight into the history of Mars' atmosphere and climate, liquid water, and planetary habitability.

NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft is nearing its scheduled Sept. 21 insertion into Martian orbit after completing a 10-month interplanetary journey of 442 million miles. Flight Controllers at Lockheed Martin Space Systems in Littleton, Colorado, will be responsible for the health and safety of the spacecraft throughout the process. The spacecraft’s mission timeline will place the spacecraft in orbit at approximately 9:50 p.m. EDT. “So far, so good with the performance of the spacecraft and payloads on the cruise to Mars,” said David Mitchell, MAVEN project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “The team, the flight system, and all ground assets are ready for Mars orbit insertion.”
