The scheduled launch of an unmanned Dragon capsule by a Falcon 9 rocket at 09:55 BST on Saturday, 19 May, should lead to one of the largest advances yet for commercial spaceflight. Both vehicles were built by SpaceX, or Space Exploration Technologies, a company established in California a decade ago that has ambitions, and now a matching order book, to become a major player in so-called space transportation.
In particular, SpaceX is contracted by NASA to develop systems to supply cargo, and eventually astronauts, to and from the International Space Station. On 22 May, provided it can demonstrate its ability to manoeuvre under control in the vicinity of the ISS, the current Dragon should become the first commercial craft to dock with the station. After delivering supplies it will be reloaded with trash and redundant clutter for a return to Earth. A controlled reentry over the Pacific, should be followed by a splashdown and recovery off the coast of California on the 31st.
Meanwhile, preparations are underway for the launch of Shenzhou 9, the fourth manned Chinese mission in nine years and the first since 2008. Its crew of three taikonauts, or yuhangyuans, may include the first Chinese woman in Space and is intended to dock with the Tiangong 1 laboratory launched in September. There has been no official declaration of a launch date or flight duration, but a launch during June and a length of some 12 or 13 days seems most likely.

Pollution is warming the atmosphere through summer thunderstorm clouds, according to a computational study published May 10 in Geophysical Research Letters. How much the warming effect of these clouds offsets the cooling that other clouds provide is not yet clear. To find out, researchers need to incorporate this new-found warming into global climate models.

Some Apples will be green. Apple data centers, that is.
The technology giant has announced that its new half-million-square-foot data center in Maiden, N.C., will only use electricity that has been generated by renewable energy. The company said that the Maiden facility will be "the most environmentally sound data center ever built."
This complements plans for a data center currently in Newark, Calif., and one planned for Prineville, Ore., to go 100 percent renewable.
'An Industry First' Two solar array installations are being built to support the North Carolina center, and both will use high-efficiency solar cells and an advanced solar tracking system. One array will be a 100-acre, 20 megawatt installation on the same site as the data center, and it will generate 42 million kilowatt-hours each year.
The other, also 100 acres, is being located several miles away, and it will produce another 42 million kWh. A bio-gas-powered 5-megawatt fuel cell installation is being constructed, and will become operational later this year. It will add another 40 million kWh.
These Apple-owned energy generators will generate 124 million kilowatt-hours of electricity annually, which will account for 60 percent of the data center's needs. The remainder will come from area providers of renewable energy.
Greenpeace Protests The data center planned for Prineville will use only renewable energy, purchased from local providers of wind, hydro and geothermal. The data center in Newark has received regulatory permission to purchase electricity from renewable sources, and expects to be 100 percent renewable by February of next year.
In a section called "Apple and the Environment" on its Web site, the company pointed out that its operations center in Austin, Texas, has been using only purchased renewable energy for nearly a decade, and now its operations centers in Sacramento, Munich, and Cork, Ireland, do as well. The corporate headquarters in Cupertino,...

Comcast has suspended its 250 GB monthly data usage threshold for its Xfinity broadband customers and plans to begin trials of new multi-tiered Xfinity data service featuring a minimum data allotment of 300 GB per month in selected U.S. markets.
The nation's largest broadband service provider said the change is being driven primarily by a dramatic rise in demand for data-intensive content such as high-definition video streaming.
Comcast said it was immediately ceasing enforcement measures associated with the Xfinity service provider's current 250 GB data usage cap. In other words, excessive data users no longer face having their accounts suspended if they repeatedly exceed their monthly data caps -- at least with respect to the duration of Comcast's coming multi-tier trials.
"We've never had any intention to limit the lawful use of the Internet or restrict our customers' ability to view online video," said Comcast Executive Vice President Cathy Avgiris in a blog post Thursday.
"The purpose of the usage threshold was simply to ensure that all of our customers were treated fairly and had a consistent and superior experience while using our high-speed data service," Avgiris said.
Piloting Two Approaches Comcast said it was still determining trial locations and expected to share more details soon.
"We'll be piloting at least two approaches in different markets, and we'll provide additional details on these trials as they launch," Avgiris said.
The new trials are expected to offer usage allowances that incrementally increase the user's allotment for each tier of high-speed data service. The new base plans in trial markets will start at 300 GB of data usage per month -- with higher tiers in 50 GB blocks costing an additional $10 per block.
Offing more flexible data usage management approaches will "ensure that all of our customers enjoy the best possible Internet...

Anyone in the market for a smartphone these days will likely see the term 4G shoved in their face by the major carriers. "We have the biggest network!" "We have the fastest speeds!"
