CAPE CANAVERAL –Engineers with the commercial space company SpaceX have analyzed two small cracks in the rear segment of the second stage engine nozzle. These cracks are located near the end of the nozzle extension where there is very little stress and so it is thought that they in themselves would not cause a flight failure. SpaceX decided that they did warrant further investigation to make sure that these cracks are not symptoms of a far larger problem.

SpaceX must have liked what they saw because the company has decided to go ahead with the launch, now scheduled for Wednesday. The launch window will open at 9 a.m. EDT and will close at 12:22 p.m. EDT.

The bell shaped Merlin Vacuum nozzle is made out of niobium sheet alloy, and is approximately 9 feet tall and 8 feet at the base. This nozzle thins out to approximately twice the thickness of a soda can near the end. Although it is composed of a refractory alloy metal and has a melting temperature high enough to boil steel, this component is, in geometric terms, the simplest component of the engine.

The niobium nozzle extension works to increase the overall efficiency of the Merlin engine while on-orbit. For this first flight of the Dragon, this efficiency is not required, but the component was placed on the rocket’s second stage by default.

SpaceX is launching the first of its Dragon spacecraft on the first demonstration flight under the $1.6 billion Commercial Orbital Transportation Services (COTS) contract that the space firm has with NASA. Under this contract SpaceX is required to fly three demonstration flights before conducting 12 supply missions to the International Space Station (ISS).

How Many Astronauts Does NASA Need?

The White House is looking into ways to reduce the number of astronauts employed by the U.S. Image Credit: NASA

CAPE CANAVERAL – When we think of NASA, the first thing that most Americans picture is the men and women of the astronaut corps. It turns out that the White House has been thinking about them as well – as maybe something that might need to be cut down. The Obama administration has requested a 10-month long study be held to determine the appropriate ‘size’ of NASA’s astronaut corps.

There are only two (and a potential third) shuttle flights remaining on the current manifest.

Right now, NASA has 64 astronauts, which some might consider a bit much if very few will be flying to space. However, if three NASA astronauts are part of each 6-member, 6-month Expedition on the International Space Station from 2011-2017 (the projected time period when NASA will be unable to launch their own astronauts) that still is 36 astronauts with a mission to space.

But the proposal to cut NASA’s astronaut corps comes on the heels of numerous successive cuts that the space agency has endured over the past year. Many view the loss of the corps as one more blow to both spaceflight experience as well as national prestige.

The White House hopes that commercial space companies such as SpaceX, which is slated to launch the second of its Falcon 9 rockets sometime this week, will emerge to fill the void created by NASA’s absence. However, to date, none of these firms have launched an astronaut into orbit. During the interim, and until NASA can build its own heavy lift vehicle, the US space agency is relying on — and paying — the Russians to bring US astronauts to the ISS via the Soyuz.

There has never been more than 150 astronauts at any given time (the most ever was 149 back in 2000). Although most Americans assume that NASA has a massive budget, for what the agency does and provides, it is incredibly small, about one-seventh of a penny out of every tax dollar helps to pay for the ISS, the shuttle program, the probes and rovers to the planets and the astronaut’s salaries. The agency’s budget is currently $18.7 billion a year. The 47 civilian astronauts earn between $65,000 and $100,000 annually, with the remaining military astronauts being paid through the Department of Defense (DoD) which NASA reimburses.

The National Academies is the organization that will conduct the review of the astronaut corps and they are leaving no stone unturned, even the T-38 ‘Talon’ jets that the astronauts fly in, are coming under scrutiny. These jets are not state-of-the-art fighters, but rather training aircraft that date back to the beginning of the space age. These planes, equipment and facilities used to train astronauts and the current number of astronauts will all be reviewed.

“I still don’t know how many folks are in the queue and were not selected for shuttle, ” said two-time shuttle astronaut Robert Springer. “If you are in the program and there is little or no chance to fly in the next 4-8 years that’s too bad, but it’s not the first time this has happened, and if you like the environment, working with some of the greatest people in the business, it can lead to challenging working on the next great enterprise.”

But some have a different idea of how NASA could cut costs.

“You know, if Obama really wanted to cut waste at NASA – he’d start with headquarters,” said a long-time NASA employee who requested to remain anonymous for fear of retribution. “That place is stocked with GS-15s – who really don’t do much of anything!” He said referring to the government pay grade of many of the high-level officials that work at NASA’s headquarters in Washington D.C.

Lockheed Martin Wants to Launch Orion Spacecraft – on a Delta IV Heavy

If everything goes according to their plan - Lockheed Martin would have their Orion spacecraft launch on a Delta IV Heavy rocket. Image Credit: NASA

After the announcement of the Vision for Space Exploration (VSE) one of the proposals to reduce the space flight ‘gap’ between the shuttle program and the Constellation Program was to attach the Crew Exploration Vehicle (CEV) to a Delta IV Heavy rocket. With all the political wrangling this simple solution appeared lost – or so it was thought. The idea of man-rating a Delta IV heavy never seemed to quite fade away and now a plan is under way to launch the Orion spacecraft on top of one of these massive launch vehicles – within the next three years.

More importantly by launching these test flights, NASA will be able to review up to three-quarters of the technical challenges involved with a flight to either the moon or to an asteroid – without risking a crew. Some of the elements that would be checked out on this unmanned test flight would be:

• Spacecraft stabilization and control.

• Parachutes used for reentry and other systems used to recover the spacecraft.

• Micrometeoroid shielding along with other systems used to protect the vehicle.

The manufacturer of the Orion spacecraft, Lockheed Martin, plans to have the first flight take place as soon as 2013. This test flight would launch from Cape Canaveral Air Force Station’s Space Launch Complex 37. If all goes well? Astronauts could be riding the Delta IV heavy to destinations such as the moon or an asteroid by 2015. For now though these plans are still in their infancy.

If all does go according to how Lockheed Martin human spaceflight engineers plan – the first mission to an asteroid could beat the 2025 date that President Obama set during his April visit to Kennedy Space Center – by ten years.

Each successive flight after the first unmanned mission would shake out the technology more and more until crews fly into orbit. The first unmanned flight, as envisioned by Lockheed Martin, would emulate many of the elements of a mission to either an asteroid or to the moon.

For long-time followers of the space program, witnessing a man-rated launch of a Delta IV heavy will very much be a blast from the past. In the early days of the space program astronauts rode Atlas and Titan rockets into orbit (these rockets were actually man-rated Cold-War missiles). Attached atop the Delta IV would be the Orion capsule and on top of that would be a Launch Abort System (LAS). This last component is a small mini-rocket that would pull the capsule up and away from the Delta if there is an emergency.

Once the flight is completed, the Orion will splashdown in the same general area as Space Exploration Technology’s (SpaceX’s) Dragon Spacecraft – the Pacific Ocean off the coast of California.

The Orion Spacecraft has proved itself to be a survivor. President Obama initially promised to support NASA’s lunar ambitions on the campaign trail – a promise he went back on once elected. He then attempted to cancel all elements of the Constellation Program of which Orion was a key part. This proposal landed with a resounding thud. He then attempted to gain support for his space plan by resurrecting Orion as a stripped down lifeboat for the International Space Station (ISS) – this too met with little support. Eventually, after much Congressional wrangling, Orion emerged as the one element of Constellation – which Obama could not kill.

Congress has put some support behind his plan to have commercial space firms provide transportation to low-Earth-orbit (LEO). However, these firms have no experience whatsoever launching men and material to orbit – and Congress wanted to have a backup plan – that meant Orion. As the launch vehicle that would have hefted Orion to orbit was effectively dead another rocket was required – the best candidate was the Delta IV heavy.

Falcon 9 Ready for Second Flight – Dragon for First

Space Exploration Technologies (SpaceX) is preparing to conduct the first demonstration launch for NASA’s Commercial Orbital Transportation Services (COTS) program, utilizing its Falcon 9 rocket. This first test flight appears to be holding solid for its targeted liftoff on Tuesday, Dec. 7. Launch will take place from the company’s launch site at Launch Complex 40 located at Cape Canaveral Air Force Station in Florida.

The launch window for this first demo flight extends from 9:03 a.m. to 12:22 p.m. EST. If it is required, launch opportunities are also open on Dec. 8 and Dec. 9 during the same general time frame. NASA TV will have coverage — you can watch it online at this link, or if you have it through your satellite or cable provider.

COTS 1, as this first flight has been dubbed, will be the first launch of the Dragon spacecraft, this will also mark the first commercial attempt to have their spacecraft reenter Earth’s atmosphere. The planned Dec. 7 flight is the first of three test launches currently envisioned in the Falcon 9 test flight series. This first flight is planned to check out important characteristics of both the Dragon spacecraft as well as the Falcon 9 launch vehicle. Some of these include orbital operations, launch elements of the combined Dragon/Falcon 9 vehicle, descent, re-entry and splashdown (which will occur in the Pacific Ocean).

NASA established the COTS program to obtain commercial launch services to jump start the commercial space industry. Under the Obama administration’s plans for the space agency, NASA will utilize these private space firms to send cargo to the International Space Station (ISS). More to the point, it is hoped that these commercial space companies can reduce the hefty price tag associated with sending something into orbit.

There will be a press conference held before the launch, it is currently planned to be held on Monday, Dec. 6, at 1:30 p.m. The conference will be held at NASA’s Kennedy Space Center press site, and will also be on NASA TV. Speakers during the press conference will include, Phil McAlister, acting director, Commercial Space Flight Development, Alan Lindenmoyer, manager, Commercial Crew and Cargo Program, Gwynne Shotwell, president of SpaceX and Mike McAleenan, Falcon 9 Launch Weather Officer 45th Weather Squadron.

If everything goes off without a hitch, a press conference will be held about an hour after splashdown takes place. If this mission is a success it will go along way to reinforcing the success of the first launch of the Falcon 9, held this past June. More importantly it will prove the viability of the Dragon spacecraft.

The Fall and Rise of ‘X’

As the X-37B ends its first mission and the X-34 program looks at a potential new start - are we at the dawn of a new age of 'X'? Photo Credit: NASA

They are at the very edge of current U.S. technological capabilities; one is a supposedly mothballed technology test-bed, the other a super-secret space plane that is currently on orbit – but set to land soon. They are the X-planes, experimental spacecraft that are proving out concepts and capabilities whose beginnings can be traced to the dawn of the space age.

It would appear from amateur observers on the ground that the secretive U.S. Air Force X-37B space plane – will be landing soon. This prediction is based off the fact that the craft is dropping in altitude and the more basic fact that it is nearing the limit of its orbital capabilities and has to return to terra firma. According to the U.S. Air Force, the X-37B can remain on orbit for around nine months or 270 days at maximum, this means that the craft should be landing sometime in the middle of January.

The X-37B or Orbital Test Vehicle (OTV) lifted off from Cape Canaveral Air Force Station in Florida on Apr. 22, atop an Atlas V rocket. Not much is known after launch due to a media blackout imposed by the U.S. Air Force.

The Air Force remains mum about the details surrounding the landing and recovery of the X-37B. It is known that the spacecraft will land at Vandenberg Air Force Base in California.

In many ways the craft resembles the shuttle with stubby wings, landing gear and a powerful engine that allows the craft to alter its orbit (much to the dismay of many observers on the ground). When the X-37B does touch down, it will do so at a 15,000 foot-long runway that was originally built to support the shuttle program.

The X-37B is one-quarter the size of the space shuttle. It is about 30 feet long and roughly 10 feet tall, with a 15-foot wingspan. It has a payload bay much like its larger, manned cousin – but naturally whatever that payload was for this mission – it was classified. The space plane was constructed by the Boeing Phantom Works. It is operated out of Schriever Air Force Base, Colorado. Another launch of the craft may take place as early as this March.

Meanwhile, as the X-37B is ready to head to the hangar, another X-craft appears to be given a new lease on life. Two of the X-34 spacecraft, built by Orbital Sciences Corporation (Orbital), were moved from their hangars at Dryden Flight Research Center to the National Test Pilot School located in the Mojave Desert in California. These technology test-bed demonstrator craft will be inspected by the NASA contractor with the idea of flying them once again.

The roughly 60 foot-long spacecraft were put into mothballs back in 2001. If their flight status is renewed they would add to the growing fleet of robotic spacecraft that the United States appears to be building.

The ‘X’ craft have a long and storied history in American aviation and space exploration. One of the most famous of the “X’ planes – was the legendary X-15. None other than the first man to walk on the moon, Neil Armstrong, flew in this program which tested out concepts that would be later employed in the space shuttle. As the X-37B prepares to end its first mission and the X-34 may be at the verge of a rebirth – could we be at the dawn of a new ‘X’-era? Only time will tell.

Delta IV Heavy Roars Off Launch Pad on Secret NRO Mission

CAPE CANAVERAL — United Launch Alliance (ULA) successfully launched a Delta IV Heavy rocket from Cape Canaveral Air Force Station in Florida, sending a classified surveillance satellite to space. Liftoff occurred on Nov. 21 at 5:58 p.m. EDT. The enormous rocket thundered to life, and as almost to underscore the secretive nature of the mission, the fiery exhaust was only visible for a short while before disappearing into thick clouds. However, long after the rocket was out of view, it made its journey known through its roar. The vibration was so visceral that vehicles and windows of buildings in the immediate area began to rattle with the raw power that was unleashed.

U.S. Air Force’ meteorologists predicted a 90 percent chance of acceptable weather for the launch, with only a tiny chance that winds could exceed the 20-knot limit. Winds were not an issue however and by all accounts the vehicle performed flawlessly.

The first launch attempt of the classified National Reconnaissance Office (NRO) satellite was scrubbed Friday during fueling of the Delta IV. Technicians determined that the reason for the scrub on Nov. 19 was a faulty sensor. The sensor gave incorrect temperature readings that were detected in the rocket’s three first-stage boosters. Technicians believed (correctly so) that they had resolved the issue.

The launch team rolled back the 330-foot mobile service tower earlier in the day and pumped approximately 450,000 gallons of liquid hydrogen and liquid oxygen into the twin boosters.

Tonight’s launch marked the third operational flight of the massive Delta IV Heavy since its first demonstration flight back in December of 2004.

“This mission helps to ensure that vital NRO resources will continue to bolster our national defense,” said Brig. Gen. Ed Wilson, 45th Space Wing commander. “The spectacular evening launch showcases how the 45th assures access to the high frontier and supports global operations.”

Flawless Launch of STP-S26

While the U.S. Air Force unsuccessfully tried to get a Delta IV off the ground in Florida – things worked out far better for NASA at the Kodiak Launch Complex located in Kodiak, Alaska. Friday’s Minotaur 4 rocket launch successfully accomplished its mission of placing not one – but six satellites into orbit some 400 miles above the Earth.

The mission took off just before sunset from Launch Pad 1. After launch the $170 million flight turned southeast from its launch site going out over the Pacific Ocean. The launch took place under a clear sky with the moon lighting its way.

The payload for this flight was a rather mixed bag of NASA, military and university experiments. All six of the launch vehicle’s payloads were released right on time about 30 minutes after launch. The so-called ‘FASTSAT’ for Fast, Affordable, Science and Technology Satellite automatically switched itself on upon deployment. The project is a demonstration of ways to deploy experiments and other payloads cheaply and effectively to orbit.

Four of the satellites that were onboard the STP-S26 mission included the “ESPA-class:” STPSat-2, FalconSAT-5, FASTSAT-HSV01 and FASTRAC.

The FASTSAT program is NASA’s first microsatellite designed to provide multiple customers with access to orbit – at a lower cost. The main goal of the FASTSAT flight is to prove the viability of this capability to various government, academic and industry customers. The intent is to show that you do not have to invest millions of dollars into a single, large-scale satellite to conduct experiments on orbit.

The launch vehicle itself is also rather cheap as it is comprised of spare Peacekeeper missile tech. The STP-S26 mission was powered to orbit by a Minotaur IV launch vehicle, which was provided by the Rocket Systems Launch Program. The Minotaur IV is produced by Orbital Sciences Corporation.

One of the ‘firsts’ on this flight was the utilization of the Hydrazine Auxiliary Propulsion System (HAPS) to allow for dual-orbit capabilities. It is hoped, that in future flights this could be used to allow satellites to other orbits to give them far greater flexibility.
Another first employed on this mission was the first to use the Multi-Mission Satellite Operations Center Ground System Architecture. This center is capable of operating various satellites at the same time at a minimal cost. Indeed, the overriding theme of this launch would appear to be providing access to orbit – for less.

Launch of Delta IV Delayed; Shuttle Launch Options Weighed

Those waiting for a launch from Florida’s Space Coast will have to wait a little more. The liftoff of a United Launch Alliance (ULA) Delta IV Heavy rocket has been pushed back yet again, and is now scheduled for Sunday, Nov. 21 at 5:58 p.m. EST (2258 GMT) from Space Launch Complex 37 (SLC 37) at Cape Canaveral Air Force Station. The rocket will carry a National Reconnaissance Office payload.

Delayed from the 18th, the next countdown started on Friday, but this too was not to be. As technicians started to fuel up the rocket’s twin strap on boosters encountered temperature anomalies. Engineers did not want to give an estimate as to when the rocket will be ready for launch – until they had a chance to unload the fuel and give the vehicle a closer look.

The payload for this mission is a classified spy satellite. In media advisories released by the 45th Space Wing it is described only as a ‘Galaxy 3.’ The 45th is stationed out of Patrick Air Force Base. The Delta IV Heavy is the largest rocket in the Delta 4 family, with three booster cores combined to form what is essentially a triple-bodied rocket.

As far as space shuttle Discovery, NASA managers are still keeping all their options open. Inspectors this week found a fourth crack in support beams on the external fuel tanks of the space shuttle. The work to repair the cracks is ongoing, but the teams will need to complete an engineering review and develop the necessary flight rationale in order to launch with a damaged tank. On Thursday, NASA announced that the flight will launch no earlier than Dec. 3, four days after the opening of a short end-of-year launch window.

The window closes Dec. 6. If NASA cannot get Discovery off the ground in the next available launch window, there is only one other planned launch at KSC/CCAFS for this year. This is the Dec. 7 launch of SpaceX’s Falcon-9 with its Dragon spacecraft payload. If this launch happens before the end of this year, it will mark the first demonstration flight of the $1.6 billion Commercial Orbital Transportation Services contract that the private space firm has with the space agency.

‘Mystery-Missile’ – Likely an Airplane

Screenshot of news footage of what has been dubbed the 'mystery missle.'

[/caption]

What took place in the skies above California’s coastline Monday, Nov. 8? That is still being hotly debated by experts and laymen alike. What appears to be a missile firing some 35 miles off the coast of California, near the Island of Catalina appears in a KCBS news chopper footage. The Pentagon has stated that it does not know what is displayed in the images. But instead of mystery, intrigue and government coverup, there is likely a more ordinary explanation: it was an optical illusion.

The Boeing Co. every so often will deploy aircraft from San Nicolas Island. These flights are part of an anti-missile laser testing program. However, the company has announced that it had nothing in the air on Monday. According to the Orange County Register, a very similar contrail was noted off of California Coast just one year earlier.

One possible explanation for the mysterious ‘plume’ is that it was the test firing of a new commercial space rocket – there has not been any confirmation of this.

While experts at Globalsecurity.org say that more than likely what is being viewed in the video is an aircraft and its contrail approaching the camera. That matches up with what scientists that have come forward have stated – that this is nothing more than the contrail made from a jetliner. In short, this whole sensation may have been caused over an optical illusion. One caused by a large aircraft, the sunset and the odd angle that the helicopter that collected the footage was shooting from.

Moreover, local radar did not pick up any fast-moving objects during the time of the ‘launch.’ In fact, in most of the footage the ‘missile’ or ‘rocket’ appears to barely move. For those that regularly follow launches only a single snippet of the video appears to show the fiery exhaust of a rocket – but this could also be the glint of sunlight off of metal.

According to the American Aerospace Defense Command, “there is no indication of any threat to our nation.” Neither NASA nor the U.S. Missile Defense Agency were quite as forthcoming, as these organizations did not immediately release information regarding the incident. Both the U.S. Air Force and Navy have stated that they were not responsible for whatever caused the vapor trail.

This is not the first time plane contrails have been mistaken for rocket launches. See the website Contrail Science for more information and to see similar previous events.

Cassini Instruments Offline Until Nov. 24

Cassini-Huygens Mission

NASA announced that the Cassini spacecraft in orbit around Saturn will have its suite of scientific cameras offline until at least Nov. 24. Cassini is currently in safe mode due to a malfunction in the spacecraft’s computer. This shut down all non-essential systems to prevent any further damage happening to the spacecraft. This means that all scientific efforts on the mission have been suspended until the problem can be resolved.

Although these seem like severe issues, mission managers are relatively sure that they will have no serious long-term effects on the overall mission. Cassini entered safe mode around 4 p.m. PDT (7 p.m. EDT) on Tuesday, Nov. 2. Managers want to review what took place onboard Cassini, correct what they can and ensure that this doesn’t happen again. Programmers have already ascertained that the likely cause of the problem was a faulty program code line that made its way back to Cassini.

Ordinarily when faulty code is sent from Earth to Saturn, Cassini would reject any coding that is deemed ‘bad.’ However, this did not happen in this case, causing the problem. Controllers are not totally convinced that a solar fare didn’t corrupt the code on its way out to the gas giant.

“The spacecraft responded exactly as it should have, and I fully expect that we will get Cassini back up and running with no problems,” said Bob Mitchell, Cassini’s program manager at JPL. “Over the more than six years we have been at Saturn, this is only the second safing event. So considering the complexity of demands we have made on Cassini, the spacecraft has performed exceptionally well for us.”

Cassini launched from Cape Canaveral Air Force Station back in 1997 atop a Titan rocket. In the thirteen years since that time it has entered ‘safe’ mode a total of six times.

The largest loss for Cassini’s planners is this will cost them a flyby of Titan, one of Saturn’s moons and the only moon in the solar system with an appreciable atmosphere. All is not lost however, as there are still some 53 possible flybys of the moon currently scheduled. The mission is currently planned to last until 2017.

The Cassini-Huygens mission is a cooperative program managed between NASA, the European Space Agency (ESA) and the Italian Space Agency. JPL, a division of the California Institute of Technology (Caltech) manages the Cassini program for NASA’s Science Mission Directorate located in Washington, D.C.
