Dec. 25, 2010

Launch of India's latest communication satellite GSAT-5P onboard homegrown GSLV-F06, powered by Russian cryogenic engine, failed today when the rocket developed a snag soon after lift-off from the Sriharikota spaceport.

GSAT-5P launch put off after leak today

The rocket blasted-off at around 4 pm from the second launch pad at the Satish Dhawan Space Centre at the end of the 29-hour countdown but was hit by a snag in the first stage itself, ISRO sources said.

"The incident occurred in the first stage itself", the sources said, adding, details would be disclosed later.

This is the second failure this year for ISRO after the previous GSLV mission with the country's maiden cryogenic engine hit a snag and the rocket plunged into the Bay of Bengal on April 15 this year.

GSAT-5P, carry C-band and 12 extended C-band transponders, was meant for augmenting communication services currently provided by the Indian National Satellite System.

GSAT-5P

ISRO had postponed the December 20 launch of the Geo-Stationary Launch Vehicle (GSLV-F06), in its seventh mission, after a minor leak was noticed in the Russian Cryogenic engine during the pre-countdown checks.

The last GSLV mission (GSLV-D3) failed after the malfunctioning of indigenous cryogenic stage, dampening the country's hopes of joining the elite club of five nations with such capability.

GSLV failure a 'major' setback, say ISRO scientists

Describing the failure of the GSAT-5P communication satellite launch this evening as "very tragic", India's top space scientists and strategic thinkers today said the launch vehicle going up in flames soon after the lift off was "a major setback" for ISRO.

Senior space scientist Prof Yashpal, in his first reaction to the failure of the satellite launch, said, "It is very tragic. I think something has happened in early stages. I have never heard of such a thing, as we have had several successes before."

Noting that the GSLV-F06 launch vehicle had disintegrated in its initial stages itself, Yashpal said, "We did not get up to the liquid stage. It is terribly sad that something somewhere has gone amiss. A lot of data is available. So they will be able to find out what went wrong."

He felt that this was "a freak mishap" as the early stages of the launch vehicle had been tested several times by India and have an 100 per cent success rate.

"It (the problem in the launch vehicle) cannot be something fundamentally wrong. It must be something big. It is unfortunate. This is an accident of some sort," he said.

Former ISRO engineer Madan Lal, in his remarks, said there seemed to be "some technical problem" in the first stage of the launch vehicle and not with the Russian cryogenic stage that India was using for the satellite launch this time.

"Cryogenic stage is the third stage of the launch. It (failure) appears not to be linked with the cryogenic stage," he said.

Lal said India had time and again succeeded in the early stages of the launch vehicle and that part was not a problem area for ISRO scientists.

Institute of Defence Studies and Analyses (IDSA) research fellow Ajay Lele said it was "a huge setback" for ISRO. But, he said, the scientists would be able to come back and relaunch the satellite soon.

"It was an important mission for ISRO. It is supposed to be one of the heaviest satellites ever tried by ISRO. In the business of satellite launches, failures are a part of the game," he remarked.

Where Stars Are Born

NASA - Hubble Space Telescope patch.

Dec 23, 2010

This mosaic image is the sharpest wide-angle view ever obtained of the starburst galaxy, Messier 82 (M82). The galaxy is remarkable for its bright blue disk, webs of shredded clouds and fiery-looking plumes of glowing hydrogen blasting out of its central regions.

Throughout the galaxy's center, young stars are being born 10 times faster than they are inside our entire Milky Way Galaxy, which results in a huge concentration of young stars carved into the gas and dust at the galaxy's center. The fierce galactic superwind generated from these stars compresses enough gas to make millions of more stars.

In M82, young stars are crammed into tiny but massive star clusters. These, in turn, congregate by the dozens to make the bright patches, or starburst clumps, in the central parts of M82. The clusters in the clumps can only be distinguished in the sharp Hubble images. Most of the pale, white objects sprinkled around the body of M82 that look like fuzzy stars are actually individual star clusters about 20 light-years across and contain up to a million stars.

The rapid rate of star formation in this galaxy eventually will be self-limiting. When star formation becomes too vigorous, it will consume or destroy the material needed to make more stars. The starburst then will subside, probably in a few tens of millions of years.

The observation was made in March 2006, with Hubble's Advanced Camera for Surveys' Wide Field Channel. Astronomers assembled this six-image composite mosaic by combining exposures taken with four colored filters that capture starlight from visible and infrared wavelengths, as well as the light from the glowing hydrogen filaments.

NASA Seeks Proposals For Technology Flight Demonstrations And Information About Suborbital Flight Services

NASA - patch.

Dec. 22, 2010

NASA is seeking proposals from researchers interested in testing new technologies during suborbital flights. The agency also is requesting information from commercial suborbital reusable launch vehicle providers and commercial payload integrators about carrying the technology payloads.

Parabolic flight trajectories and on suborbital reusable launch

The selected payloads will fly on aircraft that provide parabolic flight trajectories and on suborbital reusable launch vehicles capable of flying to altitudes above 62 miles. The flights will expose the payloads to reduced gravity and near-zero gravity environments.

"During these flights, researchers will be able to test their technologies in a range of microgravity environments and share their data with NASA -- data NASA can use when planning future missions," said Bobby Braun, NASA chief technologist at the agency's headquarters in Washington.

Parabolic flight

The solicitation is being made by NASA's Flight Opportunities Program, which is designed to foster development of a commercial reusable suborbital transportation industry while developing new technologies and improving microgravity research. When available, such reusable vehicles will provide lower-cost, more frequent, and more reliable access to space.

Technology flights are expected to reduce risks associated with emerging technologies and procedures, and overall space operations in future missions, by demonstrating applications in a relevant environment.

The solicitation for suborbital flights is open until Dec. 31, 2014. Applications for the first round of flights are due by Jan. 31, 2011. Responses to the request for information about services of commercial suborbital reusable launch vehicle providers are due Jan. 20, 2011. Participation in both activities is open to all categories of organizations.

Suborbital Flight - Ultimate Space Adventures

The Flight Opportunities Program, part of NASA's Office of the Chief Technologist, integrates the existing Commercial Reusable Suborbital Research and Facilitated Access to the Space Environment for Technology programs. The Flight Opportunities Program is managed at NASA's Dryden Flight Research Center in Edwards, Calif.

The announcement of opportunity can be viewed at: http://go.usa.gov/rlq

NASA-NSF Scientific Balloon Launches From Antarctica

NASA - CREAM Missions patch.

Dec. 22, 2010

NASA and the National Science Foundation launched a scientific balloon on Monday, Dec. 20, to study the effects of cosmic rays on Earth. It was the first of five scientific balloons scheduled to launch from Antarctica in December.

The Cosmic Ray Energetics And Mass (CREAM VI) experiment was designed and built at the University of Maryland. CREAM VI is investigating high-energy cosmic-ray particles that originated from distant supernovae explosions in the Milky Way and reached Earth. Currently, CREAM VI is floating at 126,000 feet above Antarctica with nominal science operations.

Balloon and BLAST

Two smaller, hand-launched space science payloads have already been launched, flown, and successfully flight terminated. They carried the Balloon Array for Radiation-belt Relativistic Electron Losses (BARREL) experiment designed and constructed at Dartmouth College. BARREL will provide answers on how and where Earth's Van Allen radiation belts, which produce the polar aurora, periodically interact with Earth's upper atmosphere. These test flights will help scientists prepare for similar flight experiments scheduled for launch in 2013 and 2014.

Next in line will be an experiment from the University of Pennsylvania called the Balloon Borne Aperture Submillimeter Telescope (BLAST). This experiment will investigate how magnetic fields impede star formation in our galaxy. BLAST’s instrumentation and telescope will collect data to make the first high-resolution images of magnetically polarized dust in a number of nearby star forming regions.

A super-pressure balloon test flight also will be conducted. The 14-million-cubic-foot NASA balloon is the largest single-cell, fully-sealed, super-pressure structure ever flown. It is twice the size of a similar balloon flown over Antarctica for 54 days from December 2008 to February 2009. NASA’s goal is to eventually develop a 26-million cubic-foot super-pressure balloon, nearly the size of a football stadium.
NASA scientific balloons are composed of a lightweight polyethylene film, similar to sandwich wrap. Flying to altitudes of nearly 25 miles, the balloons carry payloads weighing up to 6,000 pounds.

During part of each Antarctic summer, from December to February, NASA and the National Science Foundation conduct a scientific balloon campaign. Two unique geophysical conditions above Antarctica make long-duration balloon flights circumnavigating the continent possible during the three-month period.

CREAM Team posing

A nearly circular pattern of gentle east-to-west winds that lasts for a few weeks allows the recovery of a balloon from roughly the same geographic location from which it was launched and permits a flight path that is almost entirely above land. Balloons are illuminated continuously because the sun never sets during the Antarctic summer. And balloons maintain a constant temperature and altitude, which increases and stabilizes observation times. By contrast, in other areas of the world, daily heating and cooling cycles change the volume of gas in the balloon and cause it to rise and fall, severely limiting fly times.

NASA’s Wallops Flight Facility in Virginia manages the scientific balloon program for the agency's Science Mission Directorate in Washington. Under NASA safety supervision, the launch operations are conducted by the Columbia Scientific Balloon Facility in Palestine, Texas, which is managed by the Physical Science Laboratory of New Mexico State University. The National Science Foundation manages the U.S. Antarctic Program and provides logistic support for all U.S. scientific operations in Antarctica.

NASA's Space Shuttle Discovery Rolls Off Launch Pad Tuesday

NASA - STS-133 Mission patch.

Dec. 21, 2010

Space shuttle Discovery is scheduled to roll back from Launch Pad 39A to the Vehicle Assembly Building (VAB) at NASA's Kennedy Space Center in Florida for additional work related to its final scheduled mission. The first motion of the shuttle is targeted for 12:30 a.m. EST on Tuesday, Dec. 21 (today).

Space Shuttle Discovery rolls toward Launch Pad 39B

In the VAB, technicians will scan below the foam insulation surrounding the intertank section of Discovery's external tank to look for any issues, such as cracks. They also will reapply foam after removing 89 sensors from the tank's aluminum skin following an instrumented tanking test on Dec. 17.

The sensors were used to measure changes in the tank as super-cold propellants were pumped in and drained out during the test. Data and analysis from the test will be used to determine what caused the tops of two, 21-foot-long support beams, called stringers, on the outside of the intertank to crack during fueling on Nov. 5. Discovery's next launch attempt is no earlier than 1:37 a.m. on Feb. 3.

External thank description

The fully assembled space shuttle, consisting of orbiter Discovery, the external fuel tank and twin solid rocket boosters, is mounted on a mobile launcher platform and will be returned to the VAB atop a crawler transporter. The crawler will travel slower than 1 mph during the 3.4-mile journey, which is expected to take about six hours.

Video highlights of the rollback will air on the NASA Television Video File segment Tuesday.

Supermassive Black Holes

NASA - Chandra X-Ray Observatory logo.

12.21.10

This two-panel graphic contains two composite images of galaxies used in a recent study of supermassive black holes. In each of the galaxies, data from NASA's Chandra X-ray Observatory are blue, and optical data from the Sloan Digital Sky survey are colored red, green and blue. The galaxy on the left, Abell 644, is in the center of a galaxy cluster that lies about 1.1 billion light years from Earth. On the right is an isolated, or "field," galaxy named SDSS J1021+131, which is located about 900 million light years away. At the center of both of these galaxies is a growing supermassive black hole, called an active galactic nucleus (AGN) by astronomers, which is pulling in large quantities of gas.

A newly published study from Chandra tells scientists how often the biggest black holes in field galaxies like SDSS J1021+131 have been active over the last few billion years. This has important implications for how environment affects black hole growth. The scientists found that only about one percent of field galaxies with masses similar to the Milky Way contain supermassive black holes in their most active phase. They also found that the most massive galaxies are the most likely to host these AGN, and that there is a gradual decline in the AGN fraction with cosmic time. Finally, the AGN fraction for field galaxies was found to be indistinguishable from that for galaxies in dense clusters, like Abell 644.

This study involves a survey called the Chandra Multiwavelength Project, or ChaMP, which covers 30 square degrees on the sky, the largest area covered of any Chandra survey to date. Combining Chandra's X-ray images with optical images from the Sloan Digital Sky Survey, about 100,000 galaxies were analyzed. Out of those, about 1,600 were bright in X-ray light, signaling possible AGN activity.

NASA Announces Lineup For Total Eclipse Of The Moon

NASA logo.

Dec. 20, 2010

NASA has planned various ways to help the public enjoy the total lunar eclipse on the night of Dec. 20 to 21.

Total Eclipse Of The Moon

Astronomers at NASA's Marshall Space Flight Center in Huntsville, Ala., will host a pair of live web chats to answer questions and help make the rare celestial experience one to remember. Marshall Center astronomer Rob Suggs will hold the first chat from 3 - 4 p.m. EST on Dec. 20 and discuss the best ways to view the eclipse. From 12 a.m. - 5 a.m., Marshall researcher Mitzi Adams will answer questions as the eclipse passes across the continental United States. A live video feed of the eclipse will be available on the chat site at: http://www.nasa.gov/connect/chat/lunar_eclipse.html

Suggs also will be available for media interviews at Marshall from 2 - 3 p.m. Dec. 20. News media interested in attending the events should contact Janet Anderson at 256-544-0034 no later than 10 a.m. Monday.

For observers on the East Coast, the eclipse will last from 1:33 - 5:01 a.m. EST. The eclipse happens when the moon passes through the shadow of Earth, and the moon's appearance changes from bright orange to blood red to dark brown and perhaps gray.
