Russian greenhouse on ISS ungoes upgrade
The Russian greenhouse on ISS underwent an upgrade today.
The onboard greenhouse was dismantled in April last year, as a need arose to replace the outdated control unit, recalled head of the Rasteniya-2 (Plants-2) experiment, chief of the laboratory of the Institute of Medico-Biological Problems (IMBP) of the Russian Academy of Sciences (RAS) Vladimir Sychev. In early 2010, the crop area of the orbital garden was extended twice – the second leaf chamber was delivered to the ISS in which the crew managed to harvest the Mizuna lettuce, before the greenhouse was dismantled. Now, the cosmonauts will plant in these two chambers different cultures – super-dwarf wheat and dwarf tomatoes.
As I described in detail in Leaving Earth, the Russians have decades of experience in growing plants in space, with the goal of not only providing a natural system to recycle the station’s atmosphere, but also giving the astronauts a morale-boosting activity (gardening) that also gives them something tasty to eat. Though the engineering has still not made it possible to germinate seeds in weightlessness and then have grow there, this will be an absolute requirement if humans are ever to travel to the planets and beyond to the stars.

New York Metropolitan Opera stars, fearing radiation, skip Japan tour
Cowards: Two New York Metropolitan Opera stars, fearing radiation, have backed out of a Japanese tour in the cities of Tokyo and Nagoya. This, despite the documented lack of radiation:
Tokyo briefly registered nominally higher radiation levels in its air and water, but they have subsided to pre-tsunami levels. There was never any scientific concern of a radiation impact on Nagoya, which is much farther away.
Meanwhile, the efforts to stabilize the reactors in Fukushima are proceeding.

Robot exploration in the Great Pyramid at Giza
Robot exploration in the Great Pyramid at Giza.
The robot explorer that took the images is named Djedi, after the magician whom Pharaoh Khufu consulted when planning the layout of the Great Pyramid. It was designed and built by engineers at the University of Leeds, in collaboration with Scoutek UK and Dassault Systemes, France.

The secret lives of cats
The un-owned feral cats had larger territories than the house cats, but both had larger territories than expected. One of the male feral cats had a home range of 1,351 acres, while the pet cats had a mean home range of about 5 acres.

Asteroid sample return mission on slate for 2016
Asteroid sample return mission on slate for NASA in 2016. The asteroid chosen in 1999 RQ36, which is significant.
The space rock has been classified as a potentially hazardous asteroid, since its orbit brings it close to Earth in the year 2182. There is an extremely remote chance (a recent study pegs it at about 1-in-1000) that the 1,900-foot-wide (579-meter) asteroid could pose a threat to Earth.
