A new space race emerges as NASA prepares to award contract to ferry supplies to space station

Lugging groceries and supplies to the astronauts on the International Space Station may not be as cool as ferrying the astronauts themselves into orbit. But the NASA contract to fly cargo to the station in unmanned rocket ships has attracted bids from high-profilecompanies in what analysts say is another indication of commercial spaceflights recent renaissance.

It appears that at least five space firms have submitted proposals for the work, including giants such as Boeing and Lockheed Martin, which didn't bother to bidon the work the last time. In a new sort of space race, the contract has touched off an intense competition between stalwart defense contractors and new space start-ups that have, in just a few years, shown they can compete.

Years ago, NASA implemented a plan to outsource transportation to the space station in low Earth orbit, saying that, with a tight budget, it needed to be focused on bigger targets, such as Mars.

Some members of Congress and others criticized the decision, saying that private industry could not be trusted with such high-stakes work and that the business of spaceflight should be left to NASA. But in the years since, NASAs decision to rely on commercial companies helped ignite the commercial space industry, which, backed by new infusions of cash and with more launches to its credit, has grown more robust.

For the past few years, two companies have been resupplying the space station, taking supplies and experiments to the orbital laboratory. Billionaire entrepreneur Elon Musks SpaceX won a $1.6 billion contract, and so far has had five successful trips, and is scheduled for a sixth in April.

The other company to win the cargo contract, Orbital Sciences, now Orbital ATK, had its unmanned rocket explode shortly after takeofflast year.That raised questions about whether NASA should be relying on the commercial sector so heavily.

But at NASA, the explosion did not dampen enthusiasm for outsourcing the work. Thats in part because of SpaceXs success. But also because given the NASAs tight budgets, it doesnt really have a choice but to hire contractors to do the work for it, analysts said.

The private space industryhas been buoyed by billionaires, such as Musk, Richard Branson, who owns Virgin Galactic, and Jeff Bezos, the Amazon.com founder who owns Blue Origin (as well as the Washington Post).

But now others are looking to invest in space as well. On a recent trip to Silicon Valley, Eric Stallmer, the president of the Commercial Spaceflight Federation, said many other investors had a palpable fear-of-missing-out vibe.

Space station preps for 'space taxis'

It will also permit NASA to increase the size of the American crew on the station, and double the amount of scientific research that the team can perform, according NASA spokesperson Stephanie Schierholz.

NASA awarded Boeing a $4.2 billion contract in September to develop a transportation capable of carrying human passengers, according to Kelly Kaplan, a spokesperson for Boeing. Other reports indicate Space X received $2.6 billion for manned space missions at the same time.

Both companies, along with others, have other space contracts with NASA.

The commercial crew program is expected to improve the quality of the research being done on the station, by getting research samples from space to scientists on the ground faster; under the terms of the contract, crew have to be returned within an hour of landing and critical cargo have to be retrieved within two hours.

"The longer you have something from microgravity sitting in gravity," said NASA's Shierholz, "the more degradation there is, and the tougher it is to study it as it would be in space."

Deep Space Flight and Communications: Exploiting the Sun …

The majority of books dealing with prospects for interstellar flight tackle the problem of the propulsion systems that will be needed to send a craft on an interstellar trajectory. The proposed book looks at two other, equally important aspects of such space missions, and each forms half of this two part book.

Part 1 looks at the ways in which it is possible to exploit the focusing effect of the Sun as a gravitational lens for scientific missions to distances of 550 AU and beyond into interstellar space. The author explains the mechanism of the Sun as a gravitational lens, the scientific investigations which may be carried out along the way to a distance of 550 AU (and at the 550 AU sphere itself), the requirements for exiting the Solar System at the highest speed and a range of project ideas for missions entering interstellar space.

Part 2 of the book deals with the problems of communicating between an interstellar spaceship and the Earth, especially at very high speeds. Here the author assesses a range of mathematical tools relating to the Karhunen-Love Transform (KLT) for optimal telecommunications, technical topics that may one day enable humans flying around the Galaxy to keep in contact with the Earth. This part of the book opens with a summary of the authors 2003 Peek Lecture presented at the IAC in Bremen, which introduces the concept of KLT for engineers and newcomers to the subject. It is planned to include a DVD containing the full mathematical derivations of the KLT for those interested in this important mathematical tool whilst the text itself will contain the various results without outlines of the mathematical proofs. Astronautical engineers will thus be able to see the application of the results without getting bogged down in the mathematics.

Boston Red Sox Players Turning Heads Early at Spring Training

Let's preface this by stating the obvious: It's really early. This isn't going to be a piece making outlandish declarations from a handful of spring training games. Instead, we'll simply look at which Boston Red Sox players are making notable impressions in the early stages of baseball's return.

USA TODAY Sports

With a down-to-earth attitude and eye-popping stuff, Matt Barnes has been the biggest winner in Fort Myers so far.

It's generally not a good sign when a player approaching his age-25 season remains stuck in prospect status for the fourth year in a row. Barnes, a 2011 first-round pick, just hasn't popped the way one-time peersJose Fernandez, Yasiel Puig or Anthony Rendonhave.

His advanced numbers have always been better than his traditional counting stats. That could indicate Barnes has been unlucky, but how accurate is that assumption if we're spanning three years and 354.1 professional innings?

Perhaps he's an outlier from the norms of what the advanced stats indicate should happen. In a sense, he would be the opposite version of someone like Matt Cain, who has outpitched his unimpressive Fielding Independent Pitching (FIP) and Expected Fielding Independent Pitching (xFIP) numbers in six of the past eight seasons.

To begin 2015, Barnes seems intent on shedding the bust label so many have been quick to slap on him. His first outing was a two-inning effort where he struck out three and allowed just one baserunner. He replicated that success almost to a tee Monday, again fanning three across two scoreless frames while notching a save.

John Farrell told Bill Ballou of Worcester'sTelegram and Gazette'sthat Barnes has been a "different guy" than who he saw in limited action last season. It was an improved fastball, one that touched 97 miles per hour, and a refined breaking ball that really caught the Red Sox manager's eye.

For thrifty suitors who believe it is the thought not the expense that matters, it could be a godsend.

With Valentine's Day looming, a supermarket price war has broken out over the traditional favourite statement of love: a dozen red roses.

Instead of the 70 that it could easily cost for a hand-tied bouquet of top-quality long-stemmed Grand Prix red roses, a chap can nip to Lidl and snap up a bunch for just 3.

That offer even undercuts its rival Aldi, which is charging 5 for its cheapest bunch.

But for admirers of Miles Teller and Keleigh Sperry, so much about this Hollywood couple is a secret, until now.

While promoting Insurgent this weekend in Los Angeles, the actor shared new details about his leading lady and how he makes a relationship last in such a demanding business. Get ready for some awww moments.

"She's lovely," he gushed to E! News. "It's been pretty easy because right now, her full-time gig is kind of being with me and before her, I would never invite a girl into that world because I didn't think I could have both."

PHOTOS: More hot couples at the 2015 Oscars

He continued, "She's allowed me to be able to really focus on acting and do what I want to do. She can come to set and visit me and hang out and doesn't really distract me from it."

What could get fans distracted are all the beautiful pics of the pair often seen on Sperry's Instagram. Whether at the Oscars' after party or lounging by the beach, the blond beauty can't help herself but post more than a few cute shots online.

"She does have a very active Instagram account so people can see where I'm at. Probably too much," he joked. "What are you going to do? I'm not going to stop traveling because she likes Instagram."

The next frontier in planet science: exo-rings

Saturn is, of course, famous for its rings, but in our solar system there are actually four planets with ring systems of one size or another. Every gas giant in our solar system has a ring that is to say, right now the evidence suggests that everygas giant could have a ring. As mankind begins to look directly at the planets of the universe outside our own solar system, any universal rule of that sort will be vitally important. Now, astronomers are gearing up to start countinggas giants outside our solar system, as a new technique allows identification ofplanetary rings from light-years away.

The technique is as simple as could be, and could even be applied to existing readings to get new information outofold studies. Right now, planets are identified mostly by looking at the change in luminosity of their parent star when the planet moves between that star and the Earth; these readings are called transits. The silhouette is recorded as a rather abstract graph, and if the graph shows thata planet blocks more light from itsstar than it ought to, given predictions for its size, there are two basic possibilities: Either your predictions were wrong in some way, or the objects apparent size is expanded somehow say, withrings.

The researchers want to go back at look at numerous results that earlier studies discarded as false positives tosee whether they might have been planets encircled by rings. If they find that their work can explain historical results more accurately than current theory (or at all), astronomers might end up buildinga list of previously abandoned celestial bodiesto revisit.

Ringed exoplanets came to prominence recently, as a so-called super-Saturn was found with rings many times the size and mass of Saturns (artists rendition at top of page). The actual identity of J1407b is not quite known, however; it could be a dwarf star, and the rings still-forming planets. Additionally, while this method can provethe existence of rings, it cant prove the non-existence of them. In other words, just because this technique doesnt see an expansion in the transit readings, doesnt mean there arent rings. All it really means is that if there are rings, they must be quite thin.

The light-blocking effect changes based on the angle of the rings to the Earth.

Thus, this techniquecant be used in any case where astronomers cant get a second size reading by adifferentmethodof measurement than transit. Without that second measurement, theres no way to tell if the planets transit is blocking more light than it ought to.

Why should astronomers care about rings, specifically? Firstly, because they couldprovide a window into the past of whicheversolar system we end up finding them within. Rings can be very diverse in their makeup and, more importantly, often let a fair amount of light through. Astronomers are great at working with partially blocked light just recently, insight into planetary atmospheres and ever weather patterns was gleaned from light leaking around the edges of a distant planet.

Rings are also often associated with moons. Ancient moon-planet collisions are one possible source of planetary rings, but moons also sometimes enforce the edges and details of a planetaryring. By orbiting in asimilarplane tothe ringsthemselves, a large body like a moon can sweep up any small particulate matter simply by running into it. So far there have been no exo-moons found, but perhaps a ringed system could alert astronomers to a good potential candidate.

Exo-planetologyis undoubtedly the fastest-growing area of astronomy. The Kepler planet-hunter was NASAs very first attempt at finding planets by their transit signatures, and it found thousands. Now, the next generation transit finder, the Transiting Exoplanet Survey Satellite (TESS, is preparing to launch in 2017 and continue that quest. If exo-rings do end up being a major source of interest for astronomers, TESS is specifically the satellite that will be used tocapture them.
