Solar sails to help keep pole-sitting satellites in their place

Pole sitting was a fad in the United States in the 1920s, but ESA is putting a modern orbital spin on the practice. Investigating advanced orbital mechanics, the space agency has concluded that it's possible to build a hybrid solar-sail/electric-propulsion satellite that could hover over either of the Earth's poles by balancing the pull of the Earth and the Sun.Read More

Akatsuki probe enters orbit around Venus

Space exploration rarely gives second chances, but the Japanese Aerospace Exploration Agency (JAXA) took advantage of a big one today. The Agency has confirmed that its Akatsuki space probe has successfully made it into orbit around the planet Venus on its second attempt. The first try was way back on December 7, 2010, when a malfunction of the main engine sent the spacecraft back into orbit around the Sun.Read More

Dawn begins transitioning to its fourth and final mapping orbit

NASA's Dawn spacecraft has begun the process of transferring to its fourth and final mapping orbit, as it continues its mission around the dwarf planet Ceres. Dawn initially made orbit around Ceres on Mar. 6, and since then has provided us with increasingly detailed images and data, unlocking many of the mysteries harbored by the enigmatic celestial body.Read More

Dawn set to move to its third mapping orbit

Having already provided us with numerous insights into the nature of the dwarf planet Ceres, NASA's Dawn spacecraft is ready to move into a new, lower mapping orbit, which will provide the most detailed views so far.Read More

MIT study on exoplanet orbits may narrow parameters in search for life

A team of researchers from MIT and Aarhus University, Denmark, have discovered that Earth-sized exoplanets orbit their parent stars in the same way that our planet orbits our own Sun – maintaining a roughly equidistant circular orbit. The discovery further narrows the characteristics of worlds that could potentially play host to extraterrestrial life.Read More

ESA's Sentinel-2A satellite arrives in French Guiana ahead of launch

ESA's Sentinel-2A satellite has arrived safely in French Guiana, ahead of its June 12 launch atop a Vega rocket. It was carried in the belly of an enormous Russian-made Antonov cargo plane, and protected within a specially-constructed air conditioned habitat. Once operational, the satellite will represent a cornerstone of the agency's Copernicus program, which is striving to revolutionize how we observe and understand our environment, and how we may be able to tackle the detrimental effects of climate change.

ESA tests the potential of grabbing derelict satellites using a simple net

The ESA has been testing the possibility of using one of mankind's earliest inventions to cope with one of its newest challenges, by testing a concept that would allow satellites to net and de-orbit space debris in a safe and controlled manner. Space debris is an ever-increasing problem, and agencies around the world are starting to take steps to preserve the low-Earth orbit environment vital for a sustainable space industry.Read More

Construction begins on Space Fence radar system

Ground was broken at the future six-acre (2.4-hectare) site of the new Space Fence radar system in a special ceremony last month on Kwajalein Atoll in the Marshall Islands. The ceremony marked the official start of construction of the system that will replace the Air Force Space Surveillance System (AFSSS) in tracking objects in orbit, including commercial and military satellites and debris from collisions.Read More
