The Indian Space Research Organisation (ISRO) on Sunday successfully launched a geosynchronous satellite launch vehicle --GSLV-D5 -- which used an indigenous cryogenic engine, putting behind it years of pain and failures. The launch vehicle lifted off from India's space port at Sriharikota precisely at 4.18 pm on a clear blue sky and delivered a copy book launch.
The GSLV-D5 injected the GSAT-14, a 1,980 kg satellite, at its precise orbit 17 minutes into the flight. It took ISRO more than 13 years to achieve this success after its first GSLV flight in 2001. ISRO kickstarted the cryogenic project almost 20 years ago.
"Today is an important day for space technology in the country. The Indian cryogenic stage performed as expected and injected the satellite to the intended orbit," said an elated K. Radhakrishnan, Chairman, ISRO, immediately after the successful launch. "Our toiling of 20 years and excruciating efforts in the last three-and-a-half years have borne fruit."
What has excited the ISRO team is the precision of the launch. According to K. Sivan, Mission Director, GSLV-D5, the satellite was injected by the launch vehicle within 40 metres of its intended orbit in perigee (closest point of the satellite to earth). "The 1,000 seconds of the GSLV- D5 flight is a fruit of 1,000 days of hard work," he said.
This success comes within four-and-a-half months of an earlier attempt that ISRO had aborted owing to a fuel leak in the liquid second stage. That incident and the previous failures had raised questions about ISRO's ability to master the advanced cryogenic technology, which till recently rested with a select countries/regions such as the US, Russia, Europe, Japan and China.
This success takes ISRO closer to its objective of positioning itself as a reliable launcher of heavier communication satellites that weigh over two tonnes in the geosynchronous orbit (an orbit where a satellite moves in tandem with the earth's rotation and thus is available to users throughout the day). A few more successful launches will establish this reliability and ISRO could soon be competing with US space agency NASA and the European Space Agency for a pie of a multi-billion dollar market.
ISRO has come a long way from the late 1990s when it acquired seven Russian-built cryogenic engines for kick-starting its GSLV programme. Further sale of cryogenic engines was stopped after the US objected to it on the grounds that such a transaction violated a missile control treaty. ISRO then started to indigenise its technology and today after many delays and frustrating failures it has finally tasted success. With a distinct cost advantage estimated to be around 25 per cent, ISRO is expected to get a large share of the market. For that it will have to next establish the reliability of the GSLV as a launch vehicle by doing more such precision launches.
ISRO has already established its reliability when it comes to launching smaller satellites using its smaller Polar Satellite Launch Vehicle (PSLV). Its workhorse launch vehicle has already put over 35 foreign satellites of various countries weighing between one kg and 712 kg in orbit, not to mention more than a dozen Indian satellites.
The GSLV's success is also critical for ISRO to move to the next stage in space exploration. Its plan to land a spacecraft on the moon and launch a manned space flight hinged on the success of the GSLV and cryogenic technology.

NASA Television will provide live coverage of the launch of Orbital Sciences Corp.'s commercial Cygnus spacecraft on Tuesday, Jan. 7 from NASA's Wallops Flight Facility in Virginia, which will be carrying two University of Colorado Boulder payloads to the International Space Station.
The two CU-Boulder payloads -- a biomedical antibiotic experiment and an educational K-12 experiment involving ant behavior in microgravity -- are slated to be launched aboard Orbital Sciences Corp.'s Antares rocket at 11:55 a.m. MST. Both experiments were designed by BioServe Space Technologies, a NASA-funded center in CU-Boulder's aerospace engineering sciences department.
The CU-Boulder biomedical experiment was designed to test the effectiveness of antibiotics in space. Past experiments by CU-Boulder and other institutions have shown bacterial susceptibility to antibiotics is significantly reduced during spaceflight, although the reason is not yet known, said CU-Boulder Associate Professor David Klaus, principal investigator on the project.
Klaus said the investigation will examine changes in the gene expression of the bacteria E. coli during exposure to different concentrations of antibiotics while in the microgravity environment of space. The hope is to locate particular genes that are key to resisting antibiotics, which could lead to improved testing on Earth as well as new drug targets or new approaches to understanding antibiotic resistance in certain diseases or infections, said Klaus.
"Previous studies carried out in microgravity have shown that bacteria are able to grow in what normally would be an inhibitory concentration of the antibiotic," said Klaus. "This investigation is aimed at characterizing the genetic basis for this response in the weightless environment of space with the intent of applying any insight gained toward combating the increasing emergence of drug-resistant pathogens here on Earth."
Co-investigators on the project include BioServe Director Louis Stodieck, a research professor in aerospace engineering, and Shawn Levy, a researcher at the HudsonAlpha Institute for Biotechnology in Huntsville, Ala. The research effort also involves CU-Boulder doctoral candidate Luis Zea.
Bacterial resistance to antibiotics kills 100,000 Americans every year and represents a roughly $20 billion expense to the U.S. government in excess health care costs, said Klaus. The experiments will be undertaken using spaceflight test tubes contained in the Commercial Generic Bioprocessing Apparatus, or CGBA, an automated, suitcase-sized incubator, all designed and built by BioServe.
The second experiment launching to ISS is known as Ants in Space, which examines foraging patterns based on the density of the common Pavement Ant, said BioServe Business Development Manager and Education Program Director Stefanie Countryman. "Past experiments by Professor Deborah Gordon, principal investigator on this project, have shown that some ant species have the ability to search areas collectively without individual communication. When ant densities are high, each ant thoroughly searches one small area in a circular, "random" walk, she said. When ant densities are low, each ant searches by walking in a relatively straight line, allowing it to cover more ground.
"Ants assess their own density at the rate at which they meet," said Countryman, who said the eight individual ant habitats on ISS will be loaded with roughly 100 ants each. "The experiment examines whether in microgravity ants will use the rate at which they meet to assess density, and so use straighter paths in the larger habitat areas. The results will be compared to ground controls, which in this case will include ant habitats in hundreds of K-12 classrooms around the world."

After a relatively short winter break, Grimm is back to bust some wesen heads. Though theres nothing all that cliffhangery from the last episode of 2013, which was Christmas-themed, the show still has some dangling plot threads to deal with, like Adalinds pregnancy.
The episode opens with the quote To kill Koschei the Deathless, first you must find his soul, which is hidden in an egg, in a duck in a lead chest buried beneath an oak tree.
We then see a jogger in red running to a cover of Sam The Sham and The Pharoahs Little Red Riding Hood, which gives it an echo of the shows pilot (though that episode opened with The Eurythmics Sweet Dreams (Are Made of This).
Just then Nick jogs by (perhaps its just hat tip). Juliette gets a call from her friend Alicia whose husband Joe beats her. Juliette wants Alicia to come and stay with her and Nick, and Alicia agrees. Nick comes home and though hes been jogging isnt sweaty.
In Vienna, Adalind has coffee with Renard and shes curious why theres a camera in her room. Renard says its because of her pregnancy, and plan to sell the Royal on the black market.
He then suggests she pick a side, specifically his. Back in Portland a young woman is praying that God will kill her when a Boris Mishkin whose eyes glow green cures her, while another a man gets an address and has plans to pay Boris back.
Boris is at a bar getting a young woman drunk (even though hes sitting next to his wife Olga) and is being toasted, and he wants everyone to celebrate, but when he goes to the bathroom hes assaulted by the man seeking revenge, but his Wesen powers send the assassin out a window, and the assassins got a wound that looks fatal.
The assassin stumbles into his apartment trying to make a phone call, but passes out. Juliette calls Alicia, but theres no answer, but just then Alicia pulls up.
Nick and Juliette offer her comfort as she cries, and then she reveals herself to be a wesen. Hank goes through physical therapy with his beautiful physical therapist, and when he tries to ask her out, hes shot down.

OTTAWA If you want to be head coach of a soccer club in Englands top four leagues, you had better fling job security out the window. Since the current season began in September, 23 coaches have been fired, which is exactly 25 per cent gone in four months.
When Malky Mackay was shown the red card by Cardiff three days after Christmas, he became the sixth Premier League boss to go. It leaves Arsene Wengers 17 years at Arsenal longer than the 19 other coaches put together.
The pressure comes from all directions the moment you begin your first training session. Losing leads to relegation. Relegation often leaves clubs financially destitute. Owners who have sunk countless millions into buying success have that sort of money because they are ruthlessly successful in business. They will not tolerate defeat.
It is a wonder why anyone would take up such a challenge, but they do. The ignominy of it all doesnt even appear to dent reputations. Men who tried and failed and still want to take another crack at it can find a new club even with losing rsums.
Look at someone like Andre Villas-Boas, who arrived with great expectations at Chelsea. Multibillionaire Roman Abramovich took him on after tossing out Roberto di Matteo, who had just led the club to the European Championship. Apparently Abramovich didnt like the playing style di Matteo used to fashion a winner.
On the sidelines, AVB often looked as if he was praying for divine intervention. When it didnt work fast enough, he was gone, too. His reward for being fired? Some $15 million by all accounts and a job across London with Tottenham, another Premier League club. That one ended on Dec. 16, putting more failure cash in the bank. The man need never work again, but Im betting he will. Maybe coaching is actually an addiction.
While winning is the only way a coach is judged, his job is far, far more than being the man directing operations from the sidelines. He has to deal with myriad elements. There is the academy, where prospects are melded into players who fit the club philosophy. There is the medical angle designed to keep players healthy. There are the player personalities, their egos.
Harry Redknapp, one of Englands most respected coaches who has been with a host of clubs in his time, can attest to player troubles better than most. He provides a frightening snapshot in his autobiography, writing about his troubles after taking on what turned out to be an unsuccessful bid to keep Queens Park Rangers in the Premier League.
He talks with horror about players being habitually late for training, many earning so much they were happier to be fined two weeks wages than to show up to work. He describes how it took him only a week or two to realize that 35-year-old New Zealander Ryan Nelsen was his best player. However, Nelsen was so disgusted with the overall attitude at QPR that he couldnt wait to leave to take on the Toronto FC coaching job.
Nelsen told Redknapp he didnt have a prayer of keeping the club up, that it was the worst dressing room he had ever been in and he didnt think there was any way the problem could be solved. Player power personified.

NASA have criticised Beyonce for including an audio clip from the 1986 Challenger shuttle accident in her new song XO. The accident saw seven crew members killed in space.
A statement was released by NASA about the song saying, "The Challenger accident is an important part of our history; a tragic reminder that space exploration is risky and should never be trivialised.
"NASA works every day to honour the legacy of our fallen astronauts as we carry out our mission to reach for new heights and explore the universe."
June Scobee Rodgers, the widow of Dick Scobee, the commander of the Challenger mission, also said, "We were disappointed to learn that an audio clip from the day we lost our heroic Challenger crew was used in the song XO. The moment included in this song is an emotionally difficult one for the Challenger families, colleagues and friends."
Beyonce has since defended her inclusion of the clip saying that it was included, "in tribute to the unselfish work of the Challenger crew with hope that they will never be forgotten".

In early 2013, Indiana University Medical School-South Bend (IUSM-SB) student Patrick Davis was feeling restless. The Miami University quarterback cum Peace Corps volunteer found his first-year medical studies demanding. But something was missing.
IUSM-SBs Raclin-Carmichael Hall, where medical students take their classes, has a courtyard with a brick walkway. Davis would pace the walkway in between classes, trying to figure out what more he needed. Little by little, almost a dozen class members joined the discussion.

Gov. Andrew Cuomo who in the past had opposed medical marijuana reportedly will announce his support in his State of the State address this week.
As first reported by the New York Times, Gov. Cuomos plan will be more restrictive than other states permitting medical marijuana use for minor ailments, allowing 20 hospitals across the state to prescribe marijuana to patients with cancer, glaucoma or other diseases that meet standards to be set by the New York State Department of Health.
Cuomo, who is up for re-election this year, no doubt is aware of polling which shows that 82 percent of New Yorkers approve of medical marijuana.
Bills allowing such use the Compassionate Care Act have passed the Democratically-controlled state Assembly, but stalled in the Republican-led state Senate.
While that may change at Cuomos urging, the Governor intends to use executive powers under a 1980 law allowing the state health commissioner to approve controlled substances for patients with certain diseases.
The move represents an important shift for Cuomo, reflecting public opinion.

PLANO (CBSDFW.COM) A freshman at Clark High School of Plano has been nominated to attend the Congress of Future Medical Leaders in February in Washington, DC.
Ryan French will represent Clark High School at the honors-only program for students who want to become physicians or go into medical research fields, according to a press release.
French was nominated by Dr. Connie Mariano, the Medical Director of the National Academy of Future Physicians and Medical Scientists.
The program is held from February 14 to 16. During that time, French and other nominated students will listen to lectures about leading medical research, receive advice from medical school officials, hear stories from patients, hear from other teen medical science prodigies; and learn about advances and the future in medicine and medical technology.
According to the release, the purpose of the event is to honor, inspire, motivate and direct the top students in the country who aspire to be physicians or medical scientists, to stay true to their dream.
This is a crucial time in America when we need more doctors and medical scientists who are even better prepared for a future that is changing exponentially, said Richard Rossi, Executive Director, National Academy of Future Physicians and Medical Scientists. Focused, bright and determined students like Ryan French are our future and he deserves all the mentoring and guidance we can give him.
