Last month, the US MAVEN space probe and the Indian MOM orbiter arrived at the planet Mars within days of one another. As part of a welcome to India as the newest interplanetary spacefaring nation, NASA Administrator Charles Bolden and K. Radhakrishnan, chairman of the Indian Space Research Organisation (ISRO), signed a pair of documents formally sealing agreements between the US and India for greater cooperation in the exploration of Mars and for a joint NASA-ISRO Earth observation mission later this decade.  Read More

Ever since the historic achievement of August 6, when Rosetta became the first unmanned spacecraft to achieve a stable orbit around a comet, mission operators have been readying themselves for the inevitable nail-biting landing attempt. Six weeks after arrival at the comet 67P/Churyumov–Gerasimenko (67P), Rosetta's handlers have tentatively announced November 12 as the date for the historic touchdown.  Read More

Artist's concept of MOM arriving in Mars orbit (Image: ISRO)

After a journey of almost a year, India’s Mars Orbiter Mission (MOM) has arrived at the Red Planet. On Wednesday at 7.29 am IST (02.29 GMT), the Indian Space Research Organisation (ISRO) confirmed that the unmanned probe had successfully executed its 24 minute and 14 second engine burn and gone into orbit around Mars. With MOM’s successful rendezvous, the number of active spacecraft now studying the planet rises to eight.  Read More

NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has successfully completed a maneuver designed to place the robotic explorer in Mars orbit. The achievement is the crowning moment in a 10-month journey through deep space, representing the culmination of millions of dollars and over a decade of planning and hard work by NASA mission operators.  Read More

CRS-4 lifting off (Image: NASA Television)

SpaceX has launched its fourth commercial mission to the International Space Station (ISS). The CRS-4 Dragon spacecraft lifted off atop a Falcon 9 booster early Sunday morning from Space Launch Complex 40 at Cape Canaveral Air Force Station, Florida at 1:52 am EDT. On board is about 5,000 lb (2,268 kg) of cargo, including the first zero gravity 3D printer and a crew of "mousetronauts."  Read More

Mission operators working from NASA’s Goddard Space Flight Center are undergoing final adjustments for orbital insertion of the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft, due to take place September 21. Achieving a stable orbit around the Red Planet would be the culmination of a 10-month voyage, during which the robotic explorer traveled 442 million miles (711 million km) after having ridden into space in November 2013 atop an Atlas V rocket.  Read More

NASA's Dawn spacecraft has recovered from an unexpected phenomenon that resulted in the robotic explorer going into safe mode on September 11, mirroring a similar event that affected the spacecraft three years ago as it approached the protoplanet Vesta. Dawn was launched in September 2007 atop a Delta II-Heavy rocket with a mission to explore Vesta and the dwarf planet Ceres.  Read More

NASA has announced that Boeing and SpaceX would provide manned spacecraft to service the I...

The dawn of manned commercial spaceflight received a major boost as NASA announced in a news conference today that Boeing and SpaceX have been chosen to ferry US astronauts to the International Space Station (ISS). The US$6.8 billion contract was divided between the two companies to cover the cost of certification of the Boeing CST-100 and the SpaceX Dragon spacecraft, one demonstration mission for each, plus six commercial missions to the station.  Read More

Landing site J (pictured on the right) has been selected as Philae's primary landing site ...

The Rosetta mission's Landing Site Selection Group has selected the primary and back up landing sites for the ESA's Philae probe ahead of an attempted touchdown on 67P/Churyumov–Gerasimenko on November 11. Selecting sites J and C as the primary and back up sites respectively was no easy task, with mission operators weighing up various factors and racing against time since the spacecraft entered orbit around the comet on August 6. Prior to this, the comet had simply been too far away to characterize.  Read More

As the European Space Agency's (ESA) Rosetta spacecraft continues its mission by accompanying comet 67P/Churyumov-Gerasimenko (67P, for short) on its journey into the inner solar system, sensing instruments have been studying it prior to an attempted a landing by Rosetta's Philae probe. As a result, the spacecraft has collected enough information to render a map of the various areas on the surface of the comet showing that it is composed of several different regions created by a range of forces acting upon the object.  Read More
