  • NASA called off a planned spacewalk of SpaceX Crew-11 on 8 January, and later cancelled the mission outright, after one of the crewmembers, Mike Fincke, was reported to have a medical complication. This was the first time that this occurred in US history.
  • On 11 January, the Pandora spacecraft was successfully launched. Pandora is designed to study the atmospheres of transiting exoplanets, with the intention of identifying targets for future observation.
Article of the month

Exoplanetary Circumstellar Environments and Disk Explorer (EXCEDE) is a proposed space telescope for NASA's Explorer program to observe circumstellar protoplanetary and debris discs and study planet formation around nearby (within 100 parsecs) stars of spectral classes M to B. Had it been selected for development, it was proposed to launch in 2019.

The spacecraft concept proposed to use a 70 centimeter diameter telescope-mounted coronagraph called PIAA (Phase Induced Amplitude Apodized Coronagraph) to suppress starlight in order to be able to detect fainter radiation of circumstellar dust. Characterizing constitution of such disks would provide clues for planetary formation (mostly in habitable zones), while already existing exoplanets can be detected through their interaction with dust disk. The project's Principal Investigator is Glenn Schneider.

Wernher von Braun with the Rocketdyne F-1 engines

Pictured here are two titans of spaceflight history: Dr. Wernher von Braun, one of the main figures of the early American space program and designer of both the Saturn V and V-2 rockets, and five (four visible) Rocketdyne F-1 engines, used on the Saturn V Dynamic Test Vehicle. Dr. von Braun's career is noted for a great number of achievements in human spaceflight, including the Apollo mission which successfully put human beings on the moon; nevertheless, it is burdened with the shadow of his activities in the Nazi Party, especially concerning his work on the V-2.

The engines behind him, in addition to being immense, have the honor of being the only engines used to get humans to the moon, as of the time of writing. Developed in the late 1950s, the 8,400 kilograms (18,500 lb) engines are still the most powerful single combustion chamber liquid-propellant rocket ever made.

  • Special report: What actually happened during the Wikimedia security incident?
    A horrifying exploit took place, which could have had catastrophic and far-reaching consequences if used maliciously; instead, it seems to have happened by accident and was used for childish vandalism. How did this happen, and what did the script actually do?
