The European Space Agency (ESA) announced that the Rosetta mission, which saw the spacecraft successfully orbit a comet and set a lander down upon its surface in a series of historic firsts, has been extended. Just days after it was revealed Philae, Rosetta’s […]

T-100 Days to 'Sleeping Beauty' Rosetta's Wake-Up Call

Rosetta and its Philae landing craft will arrive at Comet 67P/Churyumov-Gerasimenko in 2014. Less than 100 days now remain before the craft are due to be revived from their 2.5-year deep-space hibernation. Image Credit: ESA

According to the Brothers Grimm, Sleeping Beauty was condemned to sleep for 100 years, but for the European […]

Skylab's Long-Haired Messenger: The Visitation of Comet Kohoutek

Skylab and its Apollo Telescope Mount (ATM)—seen here with its “windmill” of solar arrays—was a critical asset in observing Comet Kohoutek in the winter of 1973-74. Photo Credit: NASA

Forty years ago, nine men occupied America’s first space station, high above the Earth. Much of the history of Skylab is clouded by its […]
