Mission controllers are trying to diagnose a problem that put NASA’s Kepler planet-hunting observatory in emergency mode nearly 75 million miles from Earth this week.
As Japanese ground controllers struggle to restore communications with a tumbling space telescope in orbit, the U.S. military’s space surveillance experts have eliminated one cause for the satellite’s troubles.
Japan has lost contact with the newly-launched Hitomi space telescope, and ground observations indicate the satellite has shed debris and may be tumbling in orbit more than 350 miles above Earth.
Burning a mixture of super-cold liquid hydrogen, liquid oxygen and pre-packed solid propellant, Japan’s H-2A rocket vaulted into a deep blue evening sky over the beaches of Tanegashima Island on Wednesday with a satellite that will see the surroundings of black holes better than ever before.
NASA has formally approved plans — a year ahead of schedule — for an infrared space telescope launching around 2024 to record unique wide-angle views of the cosmos, seeking answers to questions about mysterious dark energy and searching for habitable worlds around other stars.
Japan launched a pioneering observatory with X-ray vision Wednesday to peer into the mysterious, light-starved neighborhoods around black holes and study the genesis of galaxies and other cosmic mega-structures billions of light-years from Earth.
Japan’s Astro-H mission, an X-ray astronomy observatory designed to shed light on black holes and the unseen structure of the universe, lifted off aboard an H-2A rocket from the Tanegashima Space Center at 0845 GMT (3:45 a.m. EST) Wednesday.
The Japanese space agency said Thursday the launch of an X-ray astrophysics observatory is postponed from Friday due to a poor weather forecast at the Tanegashima Space Center in southern Japan.
A century after Albert Einstein predicted their existence, gravitational waves have finally been detected, tiny ripples in the fabric of spacetime that were generated when two massive black holes crashed together in a space-warping cataclysm.
Europe’s LISA Pathfinder mission crafted to demonstrate the ability to detect gravitational waves — theorized ubiquitous cosmic signals that have so far eluded discovery — has arrived at its operating post around the L1 Lagrange point nearly a million miles from Earth.
