News from Space and Spaceflights

18/05/2015 - The orbit of the International Space Station (ISS) has been successfully reboosted by the Progress M-26M cargo vehicle on Monday, after aborting the first attempt. The initial reboost attempt occurred just hours before an unrelated Proton-M launch failed, as the Russian space agency struggles to overcome a string of failures that included the recent loss of the Progress M-27M vehicle. (source: - more...)

16/05/2015 - International Launch Services (ILS) launched their Russian Proton-M rocket on Saturday, carrying the MexSat-1 (Centenario) communications satellite on what was supposed to be a multi-hour flight to its transfer orbit. Launch from Pad 39 at the Baikonur Cosmodrome in Kazakhstan was nominal, before the ascent suffered a third stage failure resulting in the loss of the mission. (source: - more...)

13/05/2015 - Orbital ATK engineers have concluded a thorough examination of the Qualification Motor -1 (QM-1) following its Static Fire test in March. The motor performed as expected, providing a green light to proceed to the QM-2 Static Fire next spring – the final test that will confirm the five segment boosters are ready to fly with the Space Launch System (SLS). Casting of the QM-2 motor segments will take place over the summer. (source: - more...)

12/05/2015 - The failure of the Progress M-27M cargo run to the International Space Station (ISS) was caused by issues with the Soyuz 2-1A third stage, Roscosmos announced on Tuesday.

09/05/2015 - Can life survive for billions of years longer than the expected timeline on Earth? As scientists discover older and older solar systems, it's likely that before long we'll find an ancient planet in a habitable zone. Knowing if life is possible on this exoplanet would have immense implications for habitability and the development of ancient life, one researcher says. In January, a group led by Tiago Campante - an astroseismology or "starquake" researcher at the University of Birmingham in the Unite ... (source: - more...)
