Trying to go to space on the cheap has had disastrous consequences in the past

When reporters asked the first U.S. man in space, Alan Shepard, what he thought about as he sat atop a Mercury launch vehicle, he's said to have responded, "The fact that every part of this ship was built by the low bidder."

That sentiment may hang heavy over the launch failure at a NASA facility near the coast of VirginiaonTuesday night. An Antares rocket fromcontractor Orbital Sciences came crashing back down onto the launch pad within momentsof the launch of a flight intended to deliver supplies to the International Space Station. The mission was unmanned, and there were no injuries reported on the ground.

The cause of the failure remain unknown. But Orbital has marketed the Antaresas a "cost effective" way to launch payloads, due at least in part on its reliance on recycled Soviet-era rocket engines a move that has drawn criticism from some, including competitor SpaceX's founder, Elon Musk. Here's what he told Wired in a 2012 interview:

One of our competitors, Orbital Sciences, has a contract to resupply the International Space Station, and their rocket honestly sounds like the punch line to a joke. It uses Russian rocket engines that were made in the 60s. I dont mean their design is from the 60s I mean they start with engines that were literally made in the 60s and, like, packed away in Siberia somewhere.

Orbital has previously acknowledged some issues with the engines, with Executive Vice President Frank Culbertson telling Space Flight Now last year that the company hasdone refurbishing work on the supply. "As we went through testing, we did discover there were some effects of aging since they had been in storage for a while, including some stress corrosion cracking," he said. "That's what we're correcting with the weld repairs and other inspections."

In May, one of the refurbished engines was destroyed in a ground testat a NASA center in Mississippi with some sourcessaying it "exploded" although the exact cause has not been disclosed. In a newsconference Tuesday night, Culbertson said a thorough investigation would need to be completed before it could determine whetherthe engine was a factor in the failure.

NASA's share of the federal budget has shrunk dramatically since the peak of the space race, and it has faced significant challenges even maintaining its ability to support current missions in recent years.

Past U.S. launch failures have sometimes been blamed on poor work by contractors, who became more directly involved in U.S. government launches after a push toward privatization aimed at lowering costs in the 1980s and 1990s.

In the late 1990s, the U.S. space industry suffered astring of problems, including three military and two civilian flight failures. The military launch failures resulted in the loss of payloads totaling more than $3 billion dollars. A broad area review report of the issues ordered by President Bill Clinton cited contractor mishaps for the bulk of the problems, saying "factory-introduced engineering and workmanshiperrors predominate."

The final report from the board that investigatedthe 2003 Columbia disaster, which cost the lives of all seven crew members aboard the space shuttle, cited "years of resource constraints" as among the factors that resulted in the accident.

Russian space station resupply rocket launches, doesn't explode

WASHINGTON, Oct. 29 (UPI) -- A day after a space station resupply rocket exploded in midair only seconds after launching from Wallops Island, in Virginia, the Russian space agency made things look embarrassingly easy -- successfully linking up a ship full of precious cargo with the International Space Station.

Launched early Wednesday morning, the Progress M-25M spacecraft (also known as 57P) docked and delivered supplies to ISS astronauts only hours after taking off from Baikonur Cosmodrome in Kazakhstan. The cargo ship was carried into space by a Russian Soyuz rocket -- three tons of supplies in tow.

The successful launch and linkup completed a reversal of fortunes and upturned the recent narratives surrounding the space programs of the U.S. and Russia. A series of high profile mistakes have had Russian space officials blushing in recent months, while commercial space flight companies in the U.S. have forged ahead with expanding capabilities and new, improved technologies.

But with the explosion of Orbital Sciences' Antares rocket Tuesday evening -- just a day after its the launch was postponed by the unexpected presence of a stray boat -- Russia's tried and true Soyuz rockets are looking a bit better.

Tuesday's explosion not only destroyed the robotic cargo ship and rocket built by the Virginia-based company, but also obliterated more than 2 1/2 tons of supply materials. NASA officials said they were investigating the mishap, but insisted ISS astronauts would manage fine without the delivery and that NASA's work with Orbital would be undeterred.

"Orbital has demonstrated extraordinary capabilities in its first two missions to the station earlier this year, and we know they can replicate that success," William Gerstenmaier, Associate Administrator of NASA's Human Exploration and Operations Directorate, said in a press release after the incident.

"Launching rockets is an incredibly difficult undertaking, and we learn from each success and each setback," Gerstenmaier added. "Today's launch attempt will not deter us from our work to expand our already successful capability to launch cargo from American shores to the International Space Station."

Ahead of Tuesday's rescheduled Antares rocket launch, NASA officials predicted the blastoff would be visible (weather permitting) up and down the Eastern Seaboard. They didn't expect, however, that it would be an exploding fireball lighting up the skies.

Rocket headed to International Space Station blows up seconds after liftoff

A rocket that was to resupply the International Space Station blew up Tuesday night a few seconds after lift-off from Wallops Island, Va. (NASA)

An unmanned rocket that was to resupply the International Space Station blew up Tuesday evening a few seconds after liftoff from Wallops Island, Va.

The Orbital Sciences rocket rose a short distance from the launchpad and then exploded in a ball of orange flames. Orbital Sciences is a private company based in Dulles, Va.

NASA confirmed that all personnel were accounted for and that there were no injuries in the explosion. However, it appeared that the explosion caused damage on the ground. Emergency personnel from nearby Virginia jurisdictions, including Chincoteague, were sent to the scene.

The cause of the explosion was not immediately known.

At a news conference Tuesday evening, NASA described the explosion as a catastrophic anomaly.

At liftoff, rockets are filled with highly volatile fuel, including kerosene, and flight is considered risky.

Officials reiterated that any specific determination of what went wrong would take time. Witness accounts of what happened varied somewhat. Some said that the rocket appeared to catch fire within seconds after liftoff, then fell back to the launchpad and exploded.

The explosion directed new attention to the commercial space flight program. In contrast to earlier years, the commercial program involves craft that are built and operated by private companies.

Officials indicated Tuesday night that they were determined to continue with the program. An Orbital Sciences official said that when the cause is identified, we will begin the necessary work to return to flight.

Heres a statement from U.S. Sen. Bill Nelson (D-FL) on todays launch explosion:

Space flight is inherently risky. As we push the frontiers of space there will be setbacks. But our commercial space ventures will ultimately be successful.

News Release: CBS Web News October 28, 2014

WALLOPS ISLAND, Va. -- An Orbital Sciences Antares rocket carrying an unmanned cargo craft bound for the International Space Station exploded into flames Tuesday evening moments after launch at NASA's Mid-Atlantic Regional Spaceport in Wallops Island, Virginia.

The countdown had seemed routine and the rocket lifted off as scheduled at 6:22 p.m. EDT, but then burst into a fireball seconds later. The debris crashed down on the launching pad, spreading fiery wreckage around the area.

NASA said all personnel are accounted for and no one was injured.

This was the first catastrophic launch failure since NASA began its commercial spaceflight effort.

The rocket was constructed by Orbital Sciences Corp., which contracts with NASA to supply the ISS. A statement from Orbital said the company has formed an "anomaly investigation board" which will work with government agencies on a probe into the explosion.

Time and Space Converge on the Luminox XCOR Pilot Professional Ana-Digi

Peerless precision with multi-functions programmed by a single crown

BANDAR SERI BEGAWAN | October 27, 2014

The Luminox Space Series enters a new orbit the launch of the new Luminox XCOR Pilot Professional Ana-Digi, made for space and Essential Gear for space pilots of USA-based private rocket engine and space flight development company, XCOR Space Expeditions. Designed with input from XCOR test pilots and astronauts and with them in mind, the Luminox XCOR Pilot Professional Ana-Digi is an analog watch with digital windows, multi-function capabilities and the added advantage of the proprietary Luminox Light Technology for constant time reading visibility in the pitch dark environment of space.

Equipped with the ETA movement 988.333 Ana-Digi movement, which is the standard for professional pilots worldwide, the Luminox XCOR Pilot Professional Ana-Digi features a single programming crown for all manipulations simply rotating, pressing or pulling out the crown is enough to operate the entire set of functions that are all especially useful to space aviators: 11100th of a second chronograph, countdown timer, GMT timezone, alarm, audible time signal (minute repeater) and calendar.

As the XCOR Lynx Mark II space shuttle re-enters the Earth's atmosphere after propulsion across the boundary of space at 103km above the sea level of the Earth, both pilot and passenger will experience 4Gs for 10 to 20 seconds as the spacecraft becomes hypersonic, or travels faster than the speed of sound. During this critical re-entry to Earth, every millisecond counts, as the pilot must time the steering of the XCOR Lynx Mark II to hit the Earth's atmosphere at a highly precise angle to protect the space shuttle from the intense friction caused by the air molecules (as there is no air in space). Timing of re-entry must be of peerless precision and this is accomplished only with the Luminox XCOR Pilot Professional Ana-Digi, which provides digital time for XCOR space pilots to synchronize their operations and accurate timing down to 11100th of a second, combined with constant and dependable time reading visibility in the pitch dark environment of space from the cutting-edge luminescence of Luminox Light Technology.

As space is a limitless entity not confined by geographical timezones, the GMT time function is required for local and destination time calculations, as well as the stopwatch feature with lap capability and the set and reset alarm for navigation of the XCOR Lynx Mark II's glide back to Earth.

The ratcheted bezel is unidirectional and constructed from titanium, and sits on an ergonomic titanium cushion casing. The dial is carbon-fibre, utilizing the same highly heat-resistant material that makes up the body of the XCOR Lynx Mark II, necessary to withstand the friction of re-entry into the Earth's atmosphere after the thrilling orbit in space. The dial and counters of this high-performance chronograph are in the same black color, and is fitted with a sturdy black leather strap, further enhancing its tech-savvy, masculine appearance.

Luminox heralds a new era in space travel

As the official watch of XCOR Space Expeditions, Luminox is committed to making passenger space flights possible for Singaporeans. "We are now entering an exciting new era of the commercialization of space travel and Luminox, in partnership with XCOR Space Expeditions, is paving the way for the common man to undergo a literally out-of-this-world experience the chance to see the Earth from space. Wearing a Luminox is an adventure like no other," said Pamela Tan, brand manager of Luminox.

The first commercial flights on the XCOR Lynx Mark II are planned tor the end of 2015 and will depart from the Curacao spaceport in the Caribbean operated by XCOR Space Expeditions. For US$100,000, Bruneians have a chance to take in a unique view of the Earth's beauty from space on the XCOR Lynx Mark II, in orbit at 103km above the Earth's atmosphere, and officially qualify as an astronaut.

Space station dodges junk from old satellite

CAPE CANAVERAL, Fla. (AP) A space station delivery mission was called off Monday, just hours after the orbiting lab had to sidestep a piece of treacherous junk.

Orbital Sciences Corp. got to within the 10-minute mark for the Virginia launch of its unmanned Cygnus capsule. But a sailboat ended up in the restricted danger zone, and controllers halted the evening countdown.

The Virginia-based company will try again Tuesday evening.

Early Wednesday afternoon, space station flight controllers steered the complex and its six inhabitants away from satellite wreckage. The debris part of an old, destroyed Russian satellite would have passed within two-tenths of a mile of the station if not for the maneuver.

Mission Control was informed of the space junk over the weekend. It is wreckage from a Kosmos satellite that was launched in 1993 and collided with an Iridium spacecraft in 2009.

Orbital Sciences Corp.'s unmanned Cygnus capsule on the pad at Wallops Island, Virginia holds 5,000 pounds of cargo for NASA, including 32 mini research satellites, a meteor tracker, and a tank of high-pressure nitrogen to replenish a vestibule used by spacewalking astronauts.

Traffic is heavy these days 260 miles up.

Just this past Saturday, a Dragon cargo ship supplied by the California-based SpaceX company its fifth departed the space station after a monthlong visit and splashed into the Pacific with a load of precious science samples.

On Wednesday, a Russian cargo ship is set to rocket into orbit from Kazakhstan and arrive at the space station the same day.

"Given all the traffic that's coming and going ... we might want to send up some of those red and green wands they use on the deck of an aircraft carrier," said Orbital Sciences' executive vice president Frank Culbertson, a former astronaut who lived on the space station more than a decade ago.

San Antonio-area student experiment to launch into space

NEWS

Foursomes project among 18 aboard International Space Station

Posted TODAY, 6:52 PM Updated TODAY, 6:58 PM

SAN ANTONIO - Four students from Hobby Middle School are riding high as they wait for their science experiment to be launched into space aboard an unmanned cargo spacecraft on its way to the International Space Station.

Their project, a crystal-growing experiment, was chosen among 54 within Northside Independent School District to be launched into space through the Student Space Flight Experiment Program.

A total of 18 student experiments will be aboard the Orbital Cygnus cargo craft as it makes its way to the ISS.

It feels really cool because school is what I do every day, and now Im known throughout it, said seventh-gradergrader, Anthony Holmes.

The foursome is made up of twoseventh-graders, Holmes and Kalista Ybarra; and two sixth-graders, Jacob Robio and Madelyn Hickman.

The group was stunned when they learned their project was chosen, and they admit their friends were impressed as well.

They're like, Oh, that's really cool. You're really smart. And I was like, 'I know I am, Ybarra said, giggling. Its really cool everyone knows about that now.

Space may make astronauts infertile, scientists fear

Previous Russian studies have shown that when male and female rats were sent into space in 1979 they did not mate at all. Another study found that when male rodents were placed in simulated zero gravity conditions they could no longer produce sperm.

Dr Joseph Tash, of the Department of Molecular and Integrative Physiology at the University of Kansas told a conference in Hawaii that there was concern that astronauts could experience the same effects.

We dont really have the human data to really determine whether what we are seeing in the animals is translatable to humans. But we are seeing big impacts in the animals, he said.

And the animals still had a strong mating urge. So a male astronaut could come back without any change in behaviour but they may be shooting blanks and maybe they are unaware there is a problem if they are trying for a baby.

It is a potential issue that needs to be looked at. Certainly the flight surgeons down at Johnson Space Centre suggest that the male astronauts cryopreserve semen and some female astronauts have elected to preserve eggs just in case it is a factor.

Dr Tash believes that space flight can disrupt important chemical reactions which must happen into the body to allow reproduction.

Astronauts report a range of problems when they are at zero gravity in a condition known as space flight syndrome. It causes bone mass loss and accelerated ageing of cells.

Dr Tash discovered that many of the systems that are shutting down in space flight syndrome are linked to the hormone oestrogen.

Cosmic radiation may also be harming fertility and is expected to increase over the next 20 years because the Sun is entering a quiet phase where there are fewer solar winds to keep radiation out of our galaxy.

Around 80 per cent of male astronauts have experienced some kind of reported visual impairment after around six to eight weeks in space. The majority need glasses when they comes back to Earth.

Super-Black Nanotube Coating Could Reveal Space Obscured by the Sun's Glare

When astronomers want to see objects that are extremely faint, they call on powerful and sensitive instruments to make them clear. The problem is that these instruments are so sensitive, the slightest bit of stray light can simply overwhelm them, making it impossible to resolve the faint object over the other light.

To overcome this problem, telescopes and other deep-space imaging devices use something called a coronagraph, a telescope attachment that blocks out stray light coming into the telescope as the instrument attempts to resolve dimmer objects that may be washed out by the light.

This fall, NASA researchers on the International Space Station will test a new super-black carbon nanotube coatingthat promises to make these coronagraphs even more effective.

The NASA researchers were compelled to look for a new coating for coronagraphs to deal with the special challenges brought on by a new, compact coronagraph NASA had developed that is roughly half the mass, volume, and cost of todays coronagraphs. But with this smaller size come greater demands on the instrument.

"Compact coronagraphs make greater demands on controlling stray light and diffraction," said Doug Rabin, a Goddard heliophysicist who studies diffraction and stray light in coronagraphs, in a press release. Rabin expects that the nanotube coating should be better at preventing stray light from reaching the focal plane of the instrument than the black paint currently used.

While space-based testing, meant to see how the coating responds to the environment of space is taking place, researchers at NASAs Goddard Space Flight Center in Greenbelt, MD, will use the material to coat a cylindrically shaped coronagraph.

If both tests prove successful, the carbon nanotube coating would replace the black paint that is currently used on coronagraphs. The enhanced coronagraph would not be limited to just the International Space Station, will likely also be used on commercial satellites that make critical space-weather-related measurements.

"We've made great progress on the coating," said Goddard optics engineer John Hagopian, in a press release. "The fact the coatings have survived the trip to the space station already has raised the maturity of the technology to a level that qualifies them for flight use. In many ways the external exposure of the samples on the space station subjects them to a much harsher environment than components will ever see inside of an instrument."

Sierra Nevada's Dream Chaser heads to space for science

The Dream Chaser, designed and built by Louisville-based Sierra Nevada Corporation's Space Systems, is aiming to be the next NASA vehicle to take humans to space. The program announced Thursday, Jan. 23, 2014, that it had acquired a launch vehicle with United Launch Alliance and was going to send its first mission in Nov. 2016. (The Denver Post | Sierra Nevada Corporation)

Sierra Nevada's Louisville-based Space Systems has a new mission: Doing science in space.

The Dream Chaser for Science, or DC4Science, is a variant of the Dream Chaser spacecraft designed as an orbiting microgravity laboratory.

"We can create a custom lab that allows us to dedicate the lab space to whatever the scientific purpose is," Space Systems vice president, Mark Sirangelo said.

The spacecraft allows for customized experimental payloads to be sent to space for three different types of missions: Short-term flights with scientist astronauts on board; uncrewed months-long missions; and longer duration missions of a year or more.

The vacuum of space is considered a purer environment in which to conduct science. Experiments currently aboard the International Space Station include research into aging, cancer cells, experimental medications and more, the findings from which can have direct applications back on Earth.

In addition to the customizable aspect, there is one major difference between experiments on board DC4Science and those being performed on the space station.

"Customers will maintain scientific intellectual property rights, free from Federal Research Laboratory regulations that govern the International Space Station," said John Roth, Space Systems' vice president of business development.

Sirangelo said CD4Science is a direct tie-in with Space Systems' Global Project space-flight program, announced in September. The program is designed to assist countries that lack the resources to build their own space program by offering them the option of buying seats aboard a Dream Chaser flight or purchasing their own spacecraft.

Filling a Gap: Bellcomms 1968 Lunar Exploration Program

Bellcomm, Inc., based near NASA Headquarters in Washington, DC, was carved out of Bell Labs in 1962 to provide technical advice to NASAs Apollo Program Director. The organization rapidly expanded its bailiwick to support nearly all NASA Office of Manned Space Flight advance planning.

In a January 1968 report, Bellcomm planners N. Hinners, D. James, and F. Schmidt proposed a mission series designed to fill a gap which they felt existed in NASAs lunar exploration schedule between the first piloted Apollo lunar landing and later, more advanced Apollo Applications Program (AAP) lunar flights. The trio declared that their plan was based upon a reasonable set of assumptions regarding hardware capability and evolution, an increase in scientific endeavor, launch rates, budgetary constraints, operational learning, lead times, and interaction with other space programs, as well as the assumption that lunar exploration will be a continuing aspect of human endeavor.

To bridge the gap between early Apollo and AAP, they envisioned a series of 12 lunar missions in four phases. Phase 1, Apollo Lunar Landing Missions, would span the period from 1969 through 1971. The five Phase 1 flights would launch at least six months apart to give engineers and scientists adequate time to learn from each missions accomplishments and apply knowledge gained to subsequent missions. They would begin with Lunar Landing Mission (LLM)-1, the first Apollo landing.

The LLM-1 Lunar Module (LM) lander would alight on a flat, relatively smooth basaltic plain known as a mare (Latin for sea). The maria, which appear as mottled gray areas on the moons white face, cover about 20% of the Earth-facing Nearside hemisphere.

For LLM-1 and the other Phase 1 missions, the LM would have several back-up mare landing sites. Almost any mare would do for LLM-1, Hinner, James, and Schmidt argued, because the first piloted landing mission would emphasize engineering, not science. LLM-1 would test the LM, lunar space suits, and other moon exploration systems ahead of more ambitious Phase 1 missions. If all went as planned, the LLM-1 crew would stay on the moon for 22 hours and carry out two moonwalks.

The LM design used in the five Phase 1 missions would carry up to 300 pounds of payload to the lunar surface. For all five missions, this payload would include geologic tools for gathering up to 50 pounds of lunar rocks and dirt for return to Earth. LLM-2 through LLM-5 would, in addition, each carry an Apollo Lunar Scientific Experiment Package (ALSEP) geophysical station for deployment on the lunar surface. Astronauts of missions LLM-2 through LLM-5 would also perform geological traverses on foot to spots several thousand meters (that is, several kilometers) from the LM while the CSM Pilot in lunar orbit photographed the moons surface.

LLM-1 would follow a free-return flight path that would guarantee that the Apollo Command and Service Module (CSM) and attached LM would loop around the moon and return to Earth in the event that the CSMs Service Propulsion System (SPS) main engine failed en route to the moon. The SPS was meant to adjust the CSM/LM combinations course during flight to and from the moon, slow the CSM and LM so that the moons gravity could capture them into lunar orbit, and boost the CSM out of lunar orbit for return to Earth. The Bellcomm planners noted that the free-return trajectory would help to ensure crew safety but would greatly limit the percentage of the moons surface that LLM-1 could reach.

LLM-2 would, like LLM-1, be restricted by a free-return trajectory and a stay-time of 22 hours at a mare landing site. The LLM-2 astronauts would, however, carry out three moonwalks and deploy the first ALSEP, enabling them to accomplish more scientific exploration than the LLM-1 astronauts.

LLM-3, the third mission of Lunar Exploration Program Phase 1, would abandon the free-return trajectory so that it could attempt to reach a fresh crater on a mare. The crater would, Hinners, James, and Schmidt explained, act as a natural drill hole that would expose ancient rocks from deep inside the moon for sampling. The astronauts would perform three moonwalks during a surface stay that would last longer than 22 hours but less than 36 hours. LLM-4 would be similar to LLM-3, but would be targeted to a mare wrinkle ridge.

LLM-5, the final Phase 1 flight, would see an LM spend 36 hours at a mare site bordering a highlands region. The highlands of the moon, the light-colored areas on the moons disk, are ancient cratered terrain. The LLM-5 astronauts would perform four moonwalks.

Isro's human space flight endeavour inches ahead

Prashanth G N, Oct 23, 2014, Bangalore:

Taking a first flight-related step in its Human Space Flight (HSF) endeavour, Indian Space Research Organisation (Isro) will, in nearly 45 days time, launch an unmanned crew module on the experimental GSLV MK III flight.

The date of the launch will be finalised at a review meeting immediately after Deepavali celebrations. We will examine all aspects of the crew module and the MK-III flight after which comes the launch window and date, Isro chairman K Radhakrishnan told Deccan Herald.

He said: The government had sanctioned Rs 145 crore towards the HSF programme. With that funding we have been able to develop a crew module that will fly the astronauts to space, space suits, life support systems and a host of technologies relevant to the HSF. The first test trial, that of the crew module, will be undertaken in November last week or December first week on the GSLV MK-III.

The crew module will be injected into orbit by the GSLV at a height of 110-120 km in space from where it will fall towards the earth and be recovered from sea. Isro will examine how the crew module and thermal shield around it handle the heat and temperatures during re-entry into the earths atmosphere.

The modules behaviour during re-entry will determine the technologies to be developed for the manned space flight. The Indian Air Force will conduct trials of retrieving the crew module from sea after a soft-landing. The three-and-a-half tonne module will transport two astronauts to space. The astronauts inside the module will be able to see flight data during the flight.

Once injected into orbit at a height of 270 km in the actual flight, the module will orbit the earth for seven days and then prepare itself for the flight back to the earth. The module has to withstand temperatures running to 1,500 degrees centigrade during the re-entry.

The heat shields will have to shake off the pressure on its re-entry. In February 2003, the US space shuttle Columbia disintegrated during re-entry as the thermal heat shields could not withstand the heat.

The manned flight to space will be undertaken after these tests pass the space-quality criterion. The GSLV MK-III has made at least four to six successful test flights, which means the HSF may take pace by 2020.

Isros model of building critical technologies, launch vehicles and satellites at lower budgets has helped in the HSF project too. Besides, several public and private sector companies have helped it build the module.
