Guest guest Posted December 8, 2006 Report Share Posted December 8, 2006 Friday, 8 December 2006, 02:51 GMT Shuttle night lift-off postponed Nasa has called off the launch of its third space shuttle mission in six months because of poor weather. The crew were seated inside the space shuttle Discovery at the scheduled launch time of 2135 (0235 GMT), but low clouds prevented lift-off. The launch was scheduled to be the first night launch of the orbiter since the Colombia accident in 2003. Nasa is racing to finish work on the International Space Station (ISS) before the fleet is retired in 2010. A British-born astronaut, Nicholas Patrick, is due to fly aboard Discovery. A cold front was forecast to bring low clouds into central Florida on Thursday evening. A launch appeared possible until the last moments of the launch window despite weather forecasts putting the chances at just 40%. But controllers called off the launch when weather systems revealed no break in the clouds over Cape Canaveral. " We gave it the best shot and didn't get clear and convincing evidence that the cloud ceiling had cleared for us, " launch director Mike Leinbach told the shuttle's seven astronauts. Commander Mark Polansky urged the crew " not to be too disappointed " . Five of the astronauts were preparing for their first shuttle flight. The forecast is worse for Friday, with only a 30% chance of favourable weather. 'Complex mission' Nasa has described the construction mission as one of the most complex to date. On the previous shuttle flight in September, astronauts delivered new solar arrays to provide power for additional modules scheduled to be installed next year. The tricky task of wiring the arrays into the ISS power grid falls to the crew of shuttle Discovery. This will need to be done without interrupting the station's life-support and other critical systems. Astronauts will also switch the station off its temporary power system, a step Nasa had planned to do in 2003. Half the outpost will be powered down while astronauts make the new electrical connections during two separate spacewalks. It will be a tense time, with little back-up power if other problems arise. " Many of us consider this the most challenging flight that the International Space Station will have done since we began the effort of assembling it, " said space station manager Mike Suffredini. Station completion The only visual change in the outpost will be the addition of a small segment to the space station's exterior truss. But if all goes well, Nasa may have put its biggest construction hurdle behind it. At least 14 more missions are needed to finish the $100bn (£51bn) station. Discovery's flight is scheduled to last 12 days, with landing targeted for 19 December at the Kennedy Space Center in Florida. Discovery's crew consists of commander Mark Polansky, pilot William Oefelein and mission specialists Robert Curbeam, Joan Higginbotham, Nicholas Patrick, Sunita Williams and the European Space Agency astronaut Christer Fuglesang. Sunita Williams will be making a one-way trip. She is to remain aboard the space station, replacing Germany's Thomas Reiter, who will return with the rest of the Discovery crew. Night time launches The US space agency says it would prefer to launch Discovery during the daytime. Daytime launches give cameras a better view of the tank as the shuttle climbs to orbit. But the shuttle would need to be able to fly both night and day if the construction programme on the orbiting platform was to be completed within four years. Managers believe the shuttle's fuel tank has been improved to the point that foam debris shedding from the tank during launch - which triggered the Columbia accident - is no longer a threat. A briefcase-sized chunk of foam damaged Columbia's wing on lift-off, allowing superheated gasses to penetrate the heat shield as it returned to Earth in February 2003. All seven astronauts were killed in the disaster. http://news.bbc.co.uk/2/hi/science/nature/6216798.stm Dear David and list, The launch did not happen. Best wishes, Jorge jorge angelino [jorge.angelino] quarta-feira, 6 de Dezembro de 2006 20:11 'SAMVA ' RE: NASA - Weather favorable for Thursday shuttle launch Dear David, From the muhurta chart, I am not so sure about a successful launch. But if it happens so, it seems that problems will come later on. Think for example about the transits on December 10, at 12 GMT: Dasha: Ju/Ma/Me Transit Jupiter, L6, will be afflicting natal Jupiter and natal Mars. Natal Jupiter will be afflicting transit Jupiter, transit Mars and transit Mercury. All operational planets will be afflicted. Natal Moon is weak. Saturn is retrograde. Transit Moon will be afflicted by the MMP. Natal Venus and transit Venus, L4, are badly placed in H6, and its dispositor is exactly afflicted by itself. I hope I am wrong. Best wishes, Jorge SAMVA [sAMVA ] On Behalf Of David Hawthorne quarta-feira, 6 de Dezembro de 2006 17:34 SAMVA Re: NASA - Weather favorable for Thursday shuttle launch dear jorge: thanks for posting this data and info... in viewing the " muhurta " chart for the liftoff, we find: Dec. 7th, 2006 9:35 p.m. Cape Caneveral, Florida (FL) USA 80W36:18 28N24:20 Timezone: 5 DST: 0 This gives Cancer rising sign at 18:04 degrees. None of the malefic planets, Rahu, Ketu, Jupiter and Saturn are close to the MEP, thus reducing the chance for grave mishaps and misfortune. The main period ruler is the functional malefic (FM) Jupiter, the sub period ruler is the functional benefic (FB) Mars. Jupiter appears to be well placed, and is supported by the benefics Mars and Mercury. Mars, although close to FM Jupiter, appears to be strong in degrees and in its own sign of Scorpio, and is supported by the FB Mercury. Moon, ruling the chart is weak in infant state, but is well placed in its own sign in the first house, and is about 140 degrees from the Sun, in good strength. Sun, ruling status, is well placed and blesses the fifth and eleventh house, due to its close position to the MEP. Venus, ruling fixed assets and property is weak in the house of conflict and fire. Overall, the chart seems to support a successful launch and return. Best wishes, David Hawthorne - jorge angelino SAMVA Wednesday, December 06, 2006 2:27 AM NASA - Weather favorable for Thursday shuttle launch Weather favorable for Thursday shuttle launch POSTED: 2:58 p.m. EST, December 5, 2006 CAPE CANAVERAL, Florida (AP) -- The weather forecast for the planned liftoff of Discovery was downgraded slightly Tuesday but still remained favorable for the first night space shuttle launch in more than four years. Concerns about clouds over the Kennedy Space Center at the launch time of 9:35 p.m. EST Thursday caused forecasters to reduce the chances of favorable weather to 70 percent from 80 percent. Strong wind was expected on Friday and Saturday, diminishing the chances of good launch weather for those days to 40 percent. " The first day is the best day weatherwise, " said Kathy Winters, shuttle weather officer. Weather will improve early next week. NASA has four launch opportunities over five days, if need be, to start the 12-day mission. The space agency likely won't attempt to launch past December 17 since flight controllers want Discovery on the ground before the new year. Shuttle computers aren't designed to make the change from the 365th day of the old year to the first day of the new year while in flight. A potential solution to the problem hasn't been thoroughly tested. However, NASA officials haven't ruled out going past December 17 if they run out of launch opportunities. http://www.cnn.com/2006/TECH/space/12/05/space.shuttle.ap/index.html -- Version: 7.5.432 / Virus Database: 268.15.13/577 - Release 06.12.2006 16:39 -- Version: 7.5.432 / Virus Database: 268.15.13/577 - Release 06.12.2006 16:39 -- Version: 7.5.432 / Virus Database: 268.15.15/579 - Release 07.12.2006 13:31 Quote Link to comment Share on other sites More sharing options...
