Engineers have decided to keep the New Horizons spacecraft on its original fly-by path past Pluto, scheduled for July 2015.
Engineers have decided to keep the New Horizons spacecraft on its original fly-by path past Pluto, scheduled for July 2015.
The New Horizons team recently completed an 18-month study of potential impact hazards – mostly dust created by objects hitting Pluto’s small satellites – the spacecraft would face as it speeds some 30,000 miles per hour (more than 48,000 kilometers per hour) past Pluto in July 2015. The team estimated that the probability of a mission-ending dust impact was less than 0.3 percent if the spacecraft followed the current baseline plan, far below some early, more conservative estimates. So, with the concurrence of an independent review panel and NASA, the project team expects to keep New Horizons on this baseline course, which includes a close approach of about 12,500 kilometers (nearly 7,800 miles) from the surface of Pluto.
The count of candidate exoplanets found by Kepler has now risen another 503 to 3,216, of which only 132 have been confirmed.

These new exoplanets were found before the telescope failed but the data for them is only now being released.
The delays in SpaceX’s commercial launch schedule appear caused by a series of problems testing the first stage’s upgraded engines.

The article also provides this updated scheduling information:
A successful test will be key for several of SpaceX’s future ambitions, not least their upcoming increase in launch frequency, with the next Falcon 9 – the debut of the v1.1 – set to loft Canada’s space weather satellite, CASSIOPE, out of Vandenberg Air Force Base. This mission has officially slipped to August, with the likelihood it will be re-targeted to September. Focus will then switch to Cape Canaveral, with two satellite missions, the first carrying SES-8, to be followed by the Thaicom 6 launch.
I had suspected the delays were related to the upgrades to Falcon 9. This article confirms this.

Engineers in the Czech Republic have built a bicycle that can fly.

The demonstration does beg the question “Why a bike?”. Once those big, knobby tires are lifted off the ground, aren’t they rendered more or less moot? According to the project website, the central concept was to create a flying vehicle that could easily be ridden to a more suitable takeoff site and then be capable of a 3 – 5 minute flight. In order to offset the extra weight added by all the rotors, they could be used to help propel the bike along the ground, besides allowing it to fly.

Data from an experiment on Lunar Reconnaissance Orbiter has confirmed that light plastics can provide sufficient protection for humans against radiation.
Data from an experiment on Lunar Reconnaissance Orbiter has confirmed that light plastics can provide sufficient protection for humans against radiation.
This is very good news indeed. Combined with the data from Curiosity, which indicated that the radiation levels in interplanetary space were less intense that expected, it appears that radiation will not be a serious obstacle to interplanetary travel.
Now we just have to get the bone loss and vision problems solved.
