ORIGINAL STORY: NASA is on track to launch the GRAIL spacecraft at 8:37 this morning.
At 7:44 am, NASA reported that clouds in the area had not thickened, giving them cautious optimism that the launch can proceed. Watch live on NASA TV.
The GRAIL mission is a pair of spacecraft that will make a detailed map of the Moon's gravity field, providing clues as to the Moon's interior.
The delay of the GRAIL launch to tomorrow morning means that NASA is cancelling a scheduled briefing on the Internatiional Space Station (ISS) National Lab award.
The ISS National Lab award press conference had been scheduled for 9:30 am EDT tomorrow from Kennedy Space Center, right around the time for the next attempt to launch GRAIL. NASA encourages those who are interested to visit the national lab's website at http://www.nasa.gov/mission_pages/station/research/nlab/index.html or follow it on Twitter @ISS_NatLab.
Senators Kay Bailey Hutchison (R-TX) and Bill Nelson (D-FL) issued a scathing statement today on what they call the "Campaign to Undermine America's Manned Space Program."
Referring to the Wall Street Journal (WSJ) story yesterday, the Senators complained that the Obama Administration's "budget office" -- the Office of Management and Budget (OMB) -- continues to keep the independent cost assessment of the Space Launch System (SLS) and Multi-Purpose Crew Vehicle by Booz Allen "under wraps" while a "wildly inflated set of NASA cost numbers was invented, based on an imaginary 'acceleration' of SLS development." Those "contrived numbers" were "leaked" to the WSJ they assert.
They stress that "No one has proposed to accelerate development," calling it a "convenient myth." What they want is only to follow what was agreed upon in the 2010 NASA Authorization Act, an approach they say has been "validated repeatedly."
Bill Gerstenmaier, NASA's Associate Administrator for Human Exploration and Operations (HEO), said today that he is "very confident" that Russia's Soyuz rocket will be cleared for launching crews into space before the International Space Station (ISS) would have to be destaffed.
Speaking at a Space Transportation Association (STA) luncheon today, Gerstenmaier steered clear of the topics most people in attendance probably wanted to hear about - the Space Launch System, the new HEO Mission Directorate, commercial crew. Instead, he presented a very interesting and sometimes humorous discussion of "decision fatigue" both in the context of one's own life and in the lives of organizations. Later, however, he answered a few questions about the human spaceflight program.
With regard to staffing the ISS and getting the Soyuz rocket recertified for launching crews, he pointed out that if the Soyuz rocket had failed at the same point in its trajectory with a Soyuz spacecraft aboard, instead of the robotic Progress cargo spacecraft, the crew could have made a safe ballistic return to Earth. If the launch vehicle had failed a few seconds later, they could have aborted to orbit. While they would not have been able to reach the ISS, they could have made a "more normal" landing from orbit. Thus, for a crewed mission, such a launch failure would be more important from a mission success standpoint than safety.
Indeed, a Soyuz spacecraft did fail to attain orbit in 1975. Called the "April 5th Anomaly" or "Soyuz 18A," a two-man Soviet crew intended to dock with the Salyut 4 space station landed in Siberia instead because of a third-stage failure. They were safely recovered. The Soyuz spacecraft has encountered a number of anomalies over the more than 40 years it has been in use, including two that ended in fatalities - Soyuz 1 in 1967 and Soyuz 11 in 1971. There was another close call in 1983 when the Soyuz launch vehicle caught fire on the launch pad and the crew was pulled away by the emergency abort tower, landing 3 kilometers away. The two-man "Soyuz T-10A" crew survived and each flew on subsequent missions.
Gerstenmaier's point was that from a safety standpoint, if the type of failure that doomed Progress M-12M occurred on a crewed flight, the crew would have been OK. But it would have mission failure because the crew would not have reached the ISS.
He also stressed that the ISS program would be in the same predicament even if the space shuttle was still available. The Soyuz spacecraft not only takes crews to and from the ISS, but they remain docked at the ISS as lifeboats. Without Soyuz spacecraft, there would be no lifeboats, so crews could not remain for long duration missions anyway.
It should be noted, however, that if the shuttle were still flying, short missions could be flown while the shuttle remained docked with the ISS, even if the long duration missions had to be put on hold.
Gerstenmaier said that the Russians had "outbriefs" today on their current understanding of what went wrong on Progress M-12M, but he offered no details. A Babel Fish translation of a statement from the Russian space agency, Roscosmos, today refers to a blockage that caused the gas generator of the third stage engine to fail, attributing it to a "manufacturing defect" that is "random."
The Wall Street Journal (WSJ) reports today that the White House Office of Management and Budget (OMB) is experiencing "sticker shock" over the cost of the new Space Launch System and Multi-Purpose Crew Vehicle being designed to take humans beyond low Earth orbit.
The article (subscription required for full text) says that President Obama "may announce a decision on what space program the White House will ask Congress to fund in the next few weeks." The discussion centers on whether Congress will support the "more than $35 billion NASA inititally projected" through 2025 for the SLS and MPCV, or to ask for more money to accelerate the program and provide results sooner. The WSJ says that it obtained a copy of an August 19 NASA budget analysis that shows the latter approach could increase program costs by nearly 80 percent to $62 billion.

The National Research Council (NRC) today released a study assessing how large the NASA astronaut corps should be now that the space shuttle program has ended. It concluded that NASA may be cutting the size of the corps too deeply and supports retaining the T-38 training aircraft used by the astronauts.
Noting that the size of the astronaut corps has diminished from almost 150 people in 2000 to 61 in May 2011, the report cites the many uncertainties that must be taken into account when rightsizing the corps: "Viewed as a supply chain, astronaut selection and training are very sensitive to critical shortfalls because of the long lead times and long recovery time between missions, and because astronauts, trained for specific roles and missions, cannot be easily interchanged."
Thus, it concluded that "the currently projected minimum target size for the active Astronaut Corps poses a risk to the U.S. investment in human spaceflight capabilities" because it does not take into account "unexpected increases in attrition, or commercial, exploration, and new mission development tasks."
The NRC specifically recommended that NASA factor in a higher "reserve" when determining the number of NASA astronauts that are needed.
NASA uses a theoretical model to determine the "minimum manifest requirements," or how many astronauts it needs. The model is based on the number of astronauts who are in a post-flight reconditioning period, plus the number on-orbit, plus program spaceflight opportunities with a 5-year rotation. It then adds a reserve factor, which in the past was 50 percent, but recently was lowered to 25 percent for budgetary reasons, according to the report.
That model does not include "real-world constraints," however, such as needed skill mix, medical disqualification, or the desired pairing of inexperienced and experienced astronauts, the NRC concluded. Nor does it take into account "new sources of uncertainty" such as a "relatively new medical condition" -- papilledema, a swelling of the optic disk - afflicting astronauts returning from long duration missions. Thus, the NRC recommends that NASA return to a higher reserve factor when calculating the number of astronauts needed, though it did not specify what level should be used.
The committee also reviewed the need for NASA to retain astronaut training and simulation facilities and aircraft. One particularly controversial topic is whether the fleet of T-38N aircraft in which the astronauts train is still needed for what NASA calls spaceflight readiness training (SFRT). The NRC concluded that the aircraft should be retained because they teach critical decision-making skills in an operational environment:
"High-performance aircraft provide conditions including crew disorientation and rapid fluctuation in G-forces, under which the flight crew must carry out complex tasks in a stressful and potentially life-threatening environment. This combination of unique environments, demand for rapid, critical decision making, and historical evidence convinced the committee that SFRT provides experienced-based training that cannot be duplicated by current, or to the best of the committee's knowledge, projected alternative techniques or technologies."
The NRC committee was co-chaired by Fred Gregory and Joe Rothenberg. Gregory is a former astronaut and former NASA Deputy Administrator. Rothenberg is a former NASA Associate Administrator for Space Flight and former Director of NASA's Goddard Space Flight Center.
NASA's Upper Atmosphere Research Satellite (UARS) is expected to reenter the atmosphere soon. With all the concern these days about space debris cluttering Earth orbit, it should be good news to know that a big piece is about to reenter, but whether parts of it might survive reentry and reach the ground apparently is a bigger concern.
UARS was launched in 1991 via the space shuttle and provided data on chemical components of the atmosphere and data on the amount of light from the Sun in the ultraviolet and visible wavelengths until 2005. Now the satellite is expected to make an uncontrolled reentry late this month or in early October.
NASA will hold a media teleconference on Friday, September 9, at 11:00 am EDT to discuss the reentry. The satellite is 35 feet long, 15 feet in diameter, and weighs 5.7 metric tons. It's operational orbit was at 375 miles inclined at 57 degrees to the equator, the same inclination as the International Space Station.
The spacecraft poses a hazard in space, too. Last year, the space station had to maneuvered out of the way of a fragment that separated from it according to NASA's Orbital Debris Quarterly. Why that fragment and several others separated from UARS is unknown.
NASA released images today of several of the Apollo lunar landing sites taken by the Lunar Reconnaissance Orbiter (LRO). They are totally awesome! Check 'em out.
NASA's next robotic lunar exploration mission, GRAIL, is ready for launch on Thursday, but weather may delay the launch.
The twin GRAIL spacecraft will orbit the Moon, making a detailed map of the lunar gravity field that in turn will tell scientists about the composition of the Moon's interior. A science briefing on the mission will be held tomorrow, Wednesday, September 7 at 10:00 am EDT at Kennedy Space Center, FL. It will be aired on NASA TV.
The Delta II launch is scheduled for September 8 at 8:37 am EDT, with a second opportunity at 9:16 am EDT. At the moment, the forecast is only 40 percent favorable for a launch that day due to thunderstorms nearby. They can try again on Friday and Saturday before needing to take a break for crew rest time. Launch opportunities extend through October 19.
This is the last scheduled launch of a Delta II from Cape Canaveral Air Force Station, adjacent to NASA's Kennedy Space Center.
NASA's Chief Technologist, Robert (Bobby) Braun, is returning to Georgia Tech next month.
In a September 1 letter to NASA Administrator Charlie Bolden, Braun noted that his tenure at NASA on an Intergovernmental Personnel Act agreement was coming to an end and he would return to Georgia Tech in October because while he found it "professionally fulfilling, my service has been exceedingly difficult for me and my family."
Braun praised the people inside and external to NASA that helped him form the Office of Chief Technologist, and expressed optimism about the future despite the tumultuos times. Saying that he believes the changes at NASA have just begun, he added that "While such change is difficult, I believe that the more desperately an organization tries to hold on to today, the more likely it is that this same organization will not have a tomorrow. Please remember that the future starts today."
