The seven instruments selected for Mars 2020 (Image: NASA)

NASA’s Curiosity Mars rover has been trundling around the Red Planet for almost two years now, so the space agency is looking for a trade in. At a press conference in Washington DC, it announced the seven instruments selected to fly on the Mars 2020 rover mission that is scheduled to launch in July or August 2020 with a landing set for February 2021 at a yet to be determined site. The instruments were selected out of 58 proposals from US and international scientists and engineers, and represent a development cost of US$130 million.  Read More

The Earlobe Arterial Blood Collector (EABC) could allow astronauts to measure the impact o...

A novel technique developed by the Microgravity Centre, Brazil, could allow astronauts aboard the ISS to measure the effect that prolonged exposure to microgravity can have on human lung capacity. Research like this is a vital stepping stone to understanding the safety measures needed to keep astronauts alive and healthy on a long journey, such as NASA's planned mission to Mars.  Read More

Comet C/2013 A1 will pass Mars ten times closer than any observed comet has passed the Ear...

In October, Mars will encounter comet C/2013 A1 Siding Spring, which will come closer to the Red Planet than any recorded comet has passed to Earth. This spectacular event isn't just an astronomical curiosity, it’s also a potential hazard to NASA’s armada of orbiting explorers, so the space agency is taking steps to protect them from damage by the cosmic visitor.  Read More

The ESA's Rosetta spacecraft is now close enough to its target, the comet 67P/Churyumov-Gerasimenko (67P), to begin to discern some of the surface features marking the face of the lonely wanderer. Taken from a distance of 3,400 miles (5,500 km), the images will provide the first detailed insight into the comet due to be visited by Rosetta's Philae lander in November 2014.  Read More

You can land the most advanced spacecraft in history on the Mars, but if you can’t keep in touch with it, it might as well be so much scrap. To prevent that from happening, NASA has issued a Request for Information (RFI) to investigate the feasibility of using private satellites to provide communications into the 2020s between Earth and the fleet of exploration probes operating on and around Mars.  Read More

NASA has assembled a team of scientists and engineers to lay the first tentative plans for a successor platform to the Hubble and James Webb telescopes. The project, currently in the study phase, is being assessed for the technological and financial requirements needed to create so advanced a deep space observation platform.  Read More

Four new images have been released to mark the 15th anniversary of the launch of the Chand...

Today is the 15th anniversary of the launch of the Chandra X-ray Observatory. Chandra is one of NASA's "Great Observatories," along with the Hubble Space Telescope and Spitzer Space Telescope. Since its launch, its x-ray vision and high sensitivity have helped us to better understand the universe.  Read More

With the aid of NASA's Kepler spacecraft, a team of astronomers, including members from the Harvard-Smithsonian Center for Astrophysics, has discovered an exoplanet with the longest yearly cycle ever recorded. The planet, imaginatively named Kepler-421b, takes an impressive 704 days to orbit its parent, a dim type K star.  Read More

Three free-flying, bowling ball-sized robots aboard the ISS will use a 3D map to provide s...

Last week, Orbital Sciences' second commercial resupply mission delivered two Project Tango Google smartphones to the International Space Station. The sensor-filled phones will be used to create a detailed 3D map of the spacecraft, which will then help two soccer ball-sized, free-flying satellites autonomously navigate through some very tight spots.  Read More

Moving into a new neighborhood means finding a place to live, and 45 years after Neil Armstrong set foot on the Moon, our largest satellite is still notoriously short on housing. However, that may be changing as NASA announces that its Lunar Reconnaissance Orbiter (LRO) has discovered over 200 deep pits on the Moon that could not only provide scientists with deeper insights into the geology of the Moon, but could also be used as sites for future Lunar outposts.  Read More
