Fifty years ago today: the Apollo 1 launchpad fire

9:12 am

Link here.

Fifty years ago Friday, the first – but sadly not the last – fatal spaceflight accident struck NASA when a fire claimed the lives of Virgil “Gus” Grissom, Roger Chaffee, and Ed White during a training exercise at Launch Complex 34. The accident, a major setback for the struggling Apollo program, ushered in the first understanding of the “bad day” effects of schedule pressure for spaceflight and brought with it words and reminders that still echo today.

The article provides a very detailed and accurate look at the history and causes of the accident, as well as its consequences, which even today influence American space engineering.

Trump’s 1st NASA appointees suggest future policy

9:49 am

A memo released January 20 from NASA’s acting administrator accepting the job also announced the first Trump appointees to NASA. The history and policy positions of those two appointees I think once again give us a very clear indication of where NASA might be going in the coming years.

[Acting administrator Robert] Lightfoot, in the memo, said that the administration has appointed Erik Noble to serve as White House senior advisor and Greg Autry to be White House liaison. The two are the first members of the so-called “beachhead team” of administration staffers assigned to NASA, at least on a short-term basis.

Autry is an assistant professor of entrepreneurship at the University of Southern California who has been a proponent of commercial space activities. Autry was one of eight members of the agency review team, or “landing team,” assigned to NASA by the transition office of then President-elect Trump.

Noble did not serve on the landing team, but worked on the Trump campaign as a political data analyst. Noble, who earned a Ph.D. in environmental studies from the University of Colorado, spent seven years at the NASA Goddard Institute of Space Studies in New York, working on weather and climate models. [emphasis mine]

Autry, believes strongly in private space, and has also been a critic of SLS/Orion. Being placed at NASA as Trump’s first appointee strongly suggests that a Trump administration is going to accelerate the commercial space push that was begun by the Bush administration and then strongly supported by the Obama administration. It also suggests that the SLS and Orion projects are going to face a difficult future and will likely be phased out.

Noble’s appointment is more important. As a former scientist at the Goddard Institute, he is now well positioned to possibly appoint a new head to that organization, or even become its head himself. The present person in charge there, Gavin Schmidt, has increasingly become suspect as a scientist, instead appearing more as global warming political advocate. Since he took over that Institute, the climate data there has been increasingly tampered with, with past data being cooled and recent data being warmed, thus creating the impression that the Earth’s climate has been warming more than indicated by all previous research. Schmidt’s explanations for these “adjustments” (the term he uses) have never been satisfactory. He then uses the results from these “adjustments” to make annual press releases declaring each year as the “hottest” ever, though the raw data shows no such thing.

Even if Noble does not replace Schmidt, Noble appears well positioned to force Schmidt to either finally justify his data adjustments, or remove them from the data stream so that the raw data will be allowed to dominate policy decisions once again.

Bigelow proposes extending life of its ISS module beyond its two year demo

9:50 pm

Bigelow Aerospace is in negotiations with NASA to allow use on ISS of its demonstration inflatable BEAM module beyond its planned two year test mission.

BEAM is designed for a two-year mission on the ISS. The module is closed off from the rest of the station most of the time, with astronauts periodically entering BEAM to check the status of the module and instruments mounted inside.

NASA has previously indicated that it would dispose of BEAM at the end of its two-year mission, using the station’s robotic arm to detach the module and allow it to burn up in the atmosphere. There are no immediate plans, though, for use of the docking port where BEAM is installed after that two-year mission ends, opening the possibility for an extended mission.

Robert Bigelow has previously suggested there was commercial interest in the module. As a NASA press conference in April 2016 prior to the launch of BEAM, he said there were four different groups, both countries and companies, interested in flying experiments in BEAM. “We’re hoping that, maybe in half a year or something, we can get permission from NASA to accommodate these people in some way,” he said then.

It is typical NASA behavior to throw this module out after two years, rather than find a way to use it.

Boeing obtains available seats on Soyuz as result of Sea Launch settlement

10:57 pm

As part of Boeing’s settlement with Russia over the break-up of their Sea Launch partnership, the company has obtained rights to several manned Soyuz seats that are available because the Russians have cut back on the number of astronauts they are flying to ISS.

In turn, Boeing is offering these seats to NASA.

[John Elbon, vice president and general manager of space exploration at Boeing] said he expects NASA to make enter into negotiations with Boeing about the 2017 and 2018 seats shortly after a Jan. 27 deadline for companies to respond to the sources sought statement, a requirement when a government agency proposes a sole-source procurement. “Assuming that goes well, I think we would sit down and, in relatively short order, negotiate the details of this kind of arrangement,” he said.

He didn’t specify how much Boeing was proposing to charge NASA for the seats. The agency announced an agreement with Roscosmos in August 2015 for six Soyuz seats in 2018 at a total cost of $490 million, or $81.7 million per seat. “It’s a good value for NASA and the taxpayer,” Elbon said of Boeing’s proposed deal with NASA. “We wouldn’t ask them to pay more than they would have been paying before.”

What is happening here is that Boeing is trying to use these Soyuz seats as a way to recoup its losses from Sea Launch. The problem is that NASA doesn’t really need the manned flights in 2017 and 2018. They might need them in 2019, should the manned capsules that SpaceX and Boeing are building get delayed, but I am not sure that this deal will allow them to be used at that time.

NASA names acting administrator

8:36 am

NASA yesterday named Robert Lightfoot as the Acting NASA administrator, taking over from Charles Bolden when he leaves on January 20, 2017 at the start of the Trump administration.

Lightfoot is a former Director of NASA’s Marshall Space Flight Center, having begun his NASA career there in 1989. He transferred to NASA Headquarters in 2012 to serve as Associate Administrator, the highest ranking civil service position in the agency. It is traditional for the highest ranking NASA civil servant to take over as acting administrator during changes in presidential administrations. The Trump transition has not always followed traditional paths so today’s announcement provided some degree of reassurance. Bolden said the Trump transition team officially told NASA yesterday that Lightfoot will serve in that job. A mechanical engineer, he has served in many capacities at Marshall, Stennis Space Center and Headquarters, including assistant associate administrator for the space shuttle program (2003-2005) at headquarters and manager of the space shuttle propulsion office at MSFC (2005-2007). He was named MSFC Deputy Director in 2007 and Director in 2009.

Essentially Lightfoot will act as a placeholder until the new administration names its pick for the position.

NASA asteroid redirect mission delayed again

11:15 pm

Due to the uncertainty of its budget NASA has decided to delay the award of the contracts to begin work on its asteroid redirect mission (ARM).

The uncertainty is that Congress has never budgeted any real money for it. The mission was proposed by Obama but only vaguely, without any real support. First it was to be a manned mission to an asteroid, using Orion. Then it was to be an unmanned mission to bring a large asteroid closer to Earth to be later visited by astronauts in an Orion capsule. Then the large asteroid became a mere boulder, with the manned mission delayed until the unforeseen future.

I think NASA sees the writing on the wall here. They expect this vague unsupported mission to die with the next administration, and have decided it is better not to waste money on it now.

Utah climate scientists whine about possible NASA cuts

9:31 am

The squealing of pigs: In the kind of journalistic pro-government spending propaganda that I despise, the Salt Lake Tribune today published this article giving climate scientists in their local area a platform to lobby the public in favor of their NASA funding.

The article provides a quick quote from a Trump campaign official noting their strong hostility to the politicization of climate research, and then spends the rest of the article allowing scientist after scientist to condemn that position and to defend that spending, repeatedly implying that should the NASA cuts go through, the research will end and even possibly that access to the data from NASA climate satellites will be denied to the public and to the scientists. At no time does the article provide any thoughtful information to explain that Trump administration perspective, which is based on some reasonable and very justifiable concerns.

I note this article as a warning. Expect more of this very bad journalism. Most of the press are blindly liberal and Democratic Party partisans. They are going to work blindly with the climate community to help them defend their funding, without the slightest effort at objective reporting. The public should be aware of this, and see this political lobbying for what it is.

Launch of joint NOAA/NASA weather satellite delayed again

7:48 pm

Bad timing for NASA’s climate program: The launch of the first Joint Polar Satellite System (JPSS-1), a project of both NOAA and NASA, has been delayed from March 2017 to at least July because of problems with one instrument as well as delays in completing the satellite’s ground systems.

“The main factors delaying the JPSS-1 launch are technical issues discovered during environmental testing of the satellite and the Advanced Technology Microwave Sounder (ATMS) instrument,” Leslie said in a statement. ATMS issues were also one of the reasons for the previous delay. In addition, he cited “challenges in the completion of the common ground system” that will be used for JPSS and other NOAA polar-orbiting weather satellites.

The latest decays prompted NOAA to seek financial relief for the program. A provision in the continuing resolution (CR) passed Dec. 9, which funds the federal government through late April at 2016 levels, gives NOAA the authority to spend at higher levels for the JPSS program.

The goal with the JPSS program was to combine NOAA weather satellites with NASA’s climate research satellites. The program however has had technical and budgetary problems, as this is not the first launch delay or cost overrun.. Moreover, the origins of the JPSS program came from a failed effort in the 1990s and 2000s [pdf] to combine NOAA, Defense Department, and NASA weather satellites under what was then called the NPOESS program. When that program was restructured in 2010 to become JPSS the Defense Department pulled out.

Considering the strong rumors now suggesting that the Trump administration plans to slash NASA’s climate budget while shifting the remains of the program to NOAA, this delay of JPSS-1 is an especially good example of bad timing. It provides the new administration strong ammunition for such proposed changes.

NASA approves two new asteroid missions

3:05 pm

NASA has approved two new unmanned missions aimed at studying the asteroids.

Lucy will take a close look at six Trojan asteroids orbiting near Jupiter, after first visiting a main belt asteroid.

Lucy, a robotic spacecraft, is scheduled to launch in October 2021. It’s slated to arrive at its first destination, a main belt asteroid, in 2025. From 2027 to 2033, Lucy will explore six Jupiter Trojan asteroids. These asteroids are trapped by Jupiter’s gravity in two swarms that share the planet’s orbit, one leading and one trailing Jupiter in its 12-year circuit around the sun. The Trojans are thought to be relics of a much earlier era in the history of the solar system, and may have formed far beyond Jupiter’s current orbit.

Psyche will visit 16 Psyche, an unusual metal-rich asteroid made up mostly of iron and nickel.

While Psyche will use an ion engine, allowing it great freedom and even the potential to go elsewhere, like Dawn, when its primary mission is complete, I have not been able to determine whether Lucy will use conventional chemical altitude thrusters or an ion-type engine.

NASA awards more operational manned missions to SpaceX and Boeing

7:17 pm

NASA today awarded four more operational manned missions to SpaceX and Boeing, bringing their total planned flights now to six each, not counting their first demonstration mission.

The additional flights will allow the commercial partners to plan for all aspects of these missions while fulfilling space station transportation needs. The awards do not include payments at this time. “Awarding these missions now will provide greater stability for the future space station crew rotation schedule, as well as reduce schedule and financial uncertainty for our providers,” said Phil McAlister, director, NASA’s Commercial Spaceflight Development Division.

NASA essentially has no choice. These spacecraft will be the only way to get astronauts to ISS after 2018, when our contract with the Russians expires.

Moreover, by awarding these contracts now, before the end of the Obama administration, NASA essentially locks them down before the new Trump administration can take power and kill them.

Trump interested in lunar manned mission?

3:48 pm

After meeting with Donald Trump a historian now says the president-elect appears very interested in the idea of sending a man to the Moon.

All of these stories continue to be speculation, but I strongly suspect that much of it also consists of trial balloons pushed by the various supporters of SLS/Orion in their effort to give that very expensive and so-far completely unproductive boondoggle a mission it can actually achieve. Right now, SLS/Orion has no mission. It is only funded through the first manned test flight in 2021 (likely to be delayed until 2023). Since it has been a pork barrel favorite of a number of Senators and Congressmen, I would not be surprised if they are trying to convince Trump to fund it by giving it a new Kennedy-like mission.

“Anomalous readings” detected during testing of Webb telescope

9:09 am

During standard vibration testing to simulate launch, engineers have detected what they call “anomalous readings” in the James Webb Space Telescope.

During the vibration testing on December 3, at Goddard Space Flight Center in Greenbelt, Maryland, accelerometers attached to the telescope detected anomalous readings during a particular test. Further tests to identify the source of the anomaly are underway. The engineering team investigating the vibe anomaly has made numerous detailed visual inspections of the Webb telescope and has found no visible signs of damage.

It is a good sign that they have found no damage. It is also a good thing that they detected these issues now, on the ground, where they can fix them. Webb, almost a decade behind schedule and $8 billion over budget, will be placed at a point a million miles from Earth, where no repair crew will be able to reach it.
