A Scottish startup is providing a kit to help build a picosatellite on the cheap

A Glasgow-based startup is reducing the cost of access to space by offering "satellite kits" that make it easier for space enthusiasts, high schools and universities alike to build a small but functional satellite for as little as US$6,000 and then, thanks to its very small size, to launch for significantly less than the popular CubeSats.  Read More

The new CryoSat measurements show a 6.4 percent decrease in the volume of Arctic sea ice (...

The European Space Agency’s CryoSat mission has returned its latest map of Arctic sea ice volumes, recording a slight decrease in thickness over previous measurements. The data flies in the face of the previous downward trend, which was much greater, but is unlikely to indicate a shift in the accepted pattern of degradation.  Read More

The Space Data Highway, also known as the European Data Relay System (EDRS), allows for fa...

The European Space Agency (ESA) has successfully linked up the Sentinel-1A and Alphasat satellites via laser, transmitting data across almost 36,000 km (about 22,400 miles) of space. The link allows for the delivery of data to Earth in near real time, and will be used for a wide range of applications including the timely monitoring of natural disasters.  Read More

NASA has released a video depicting the initial deployment of an undertaking designed to study a phenomenon known as magnetic reconnection. The launch of the Magnetospheric Multiscale (MMS) mission will see four identical spacecraft deployed from a single Atlas V rocket, set to lift off from cape Canaveral, Florida, no earlier than March next year.  Read More

The orbiting GPS network could be used to detect waves of dark matter that pass between th...

Dark matter is hypothesized to account for the large amounts of "missing" invisible matter in the universe where visible objects such as stars, gas, and dust are insufficient to explain the total gravitational effects observed. Despite repeated and verifiable observational evidence supporting this hypothesis, the existence of dark matter remains unproven. However, recent research has suggested that the hunt for this elusive substance may be aided by detecting any changes in the synchronization between the individual atomic clocks on-board satellites in the orbiting GPS network and receivers on the ground as waves of dark matter pass between them and the surface of the Earth.  Read More

NASA has announced that it is going forward with its Ionospheric Connection Explorer (ICON). Scheduled to launch in 2017, the orbital mission aims to study the effects of the lower atmosphere on the ionosphere and its impact on the Earth’s surface.  Read More

Boeing has successfully joined two its 702SP satellites in a stacked configuration in preparation for a launch scheduled for early 2015. Aside from being the first involving conjoined satellites, the launch will also put the first satellites to enter service boasting an all-electric propulsion system into orbit.  Read More

Artist's concept of the bloostar upper stages firiing

Reaching space in a balloon may sound like something out of a children’s book, but Spain’s zero2infinity company doesn't think so. The Barcelona-based company specializes in near-space balloon flights for scientific and engineering clients, and is working on a nanosatellite launch vehicle called bloostar, which uses a high-altitude balloon as a first stage and rockets for reaching orbit.  Read More

Sentinel-1A, the first of a planned fleet of ESA satellites central to the European Commission's Copernicus environmental monitoring program, has begun its operational life. Following the completion of its commissioning and transfer to the team in charge of its operation, users now have access to data from the satellite, which will provide all-weather, day and night radar imaging for land and ocean services.  Read More

A new map of the seafloor is twice as accurate as the previous version (Image: David Sandw...

Given they aren't covered by oceans, it's maybe not so surprising that we know more about the topography of the Moon and Mars than we do about Earth's ocean depths. But researchers have evened the score at least a little with the creation of a new map of the world's seafloor. Twice as accurate as the previous version produced almost 20 years ago, the new map details thousands of previously uncharted mountains and provides new clues on the formation of the continents.  Read More
