Capitalism in space: ULA this morning successfully launched NASA TDRS-M communications satellite, following a several week delay caused by an accident during satellite preparation that forced the replacement of the satellite’s antenna.
This was ULA’s fifth launch for 2017, which is behind the once-a-month pace they have maintained for the previous five years.
Capitalism in space: The argon-fueled plasma rocket engine being developed by the Ad Astra Rocket Company has advanced its test engine firings from 30 seconds long to five minutes long.
Their $9 million contract with NASA calls for a 100-hour-long engine firing by 2018. At the moment the company says they are on schedule to meet that goal.
Failure theater: The Senate Appropriations Committee today marked up NASA’s budget, restoring almost all of the proposed cuts, including cuts to the agency’s climate programs that both the Trump administration and the House had proposed.
The only program it appears the Senate cut was NASA’s planetary program, which they trimmed by almost 25%.
This only provides more evidence that the large number of the Republicans in the Senate are not really Republicans. They certainly aren’t conservative. And it sure appears that they aren’t very smart either, considering that NASA’s planetary program is one of its most successful endeavors.
We shall see how this budget shakes out in the coming months. Overall I am not hopeful. It appears to me that this Republican Congress wants to spend big bucks, and is hell bent on doing it.
NASA has revealed that the cameras on the Transiting Exoplanet Survey Satellite (TESS) become slightly out of focus when they are cooled to -75 Celsius, the temperature they will experience in space.
NASA has also decided that the fuzziness is not enough to require a fix, and is proceeding with the mission as is, despite concerns expressed by scientists.
Alan Boss, an astronomer with the Carnegie Institution, brought up the issue in a summary of a meeting last week of the Astrophysics Advisory Committee, of which he is a member. “That could have some big effects on the photometry,” he said of the focus problem. “This is certainly a concern for the folks who know a lot about photometry.”
TESS will use those cameras to monitor the brightness of the nearest and brightest stars in the sky, an approach similar to that used by Kepler, a spacecraft developed originally to monitor one specific region of the sky. Both spacecraft are designed to look for minute, periodic dips in brightness of those stars as planets pass in front of, or transit, them. Chou said that since TESS is designed to conduct photometry, measuring the brightness of the stars in its field of view, “resolution is less important compared to imaging missions like Hubble.” However, astronomers are concerned that there will be some loss of sensitivity because light from the stars will be spread out onto a slightly larger area of the detector.
“The question is how much science degradation will there be in the results,” Boss said. “The TESS team thinks there will be a 10 percent cut in terms of the number of planets that they expect to be able to detect.”
It could be that NASA has decided that the cost and delay required to fix this is not worth that 10% loss of data.
NASA has decided to delay the launch of its TDRS-M satellite until August 20.
This simplifies their launch schedule, as it allows SpaceX to launch as planned on August 12 and thus not interfere with an August 17 Russian spacewalk that is releasing two satellites from ISS. It will also give them plenty of time to replace the antenna that was damaged during launch prep, in an incident which they still have not described in any detail.
Because of the launch delay caused by the accident that damaged the antenna of NASA’s TDRS-M communication satellite, requiring its replacement, the agency is now faced with a cascading series of scheduling problems.
They are now aiming for an August 10 launch of TDRS-M on a ULA Atlas 5. This will then force a delay in the August 12 launch of a Dragon capsule to ISS to August 14, which can’t be delayed past August 16 because of a scheduled Russian spacewalk on ISS that must happen on August 17 because it involves the release of two satellites. Making things even more complicated is Dragon’s cargo, which includes mice for a rodent experiment. If it doesn’t occur before August 16, the mice will then have to be replaced with fresh mice, causing further delays.
There is then even the chance that these scheduling problems might impact SpaceX’s scheduled August 28’s launch of the X-37B, as well as ULA’s scheduled August 31 launch of surveillance satellite.
One additional tidbit: This Dragon will be the last unused cargo capsule. All future SpaceX cargo missions will use previously flown capsules.
I should add that these scheduling issues illustrate starkly the growing need for more launch sites. There is money to be made here, fulfilling this need.
Yawn. NASA and Lockheed Martin have partnered to re-purpose a leftover shuttle cargo module into a ground-based simulated interplanetary spaceship.
Lockheed Martin announced it will refurbish the Donatello multi-purpose logistics module (MLPM), transforming from it from its original, unrealized role as a supply conveyor for the International Space Station to a test and training model of a living area for astronauts working beyond Earth orbit. The work is being done under a public-private partnership between the aerospace corporation and NASA. “We are excited to work with NASA to repurpose a historic piece of flight hardware,” said Bill Pratt, Lockheed Martin’s program manager for the deep space habitat contract, in a statement.
…Over an 18-month period, Lockheed Martin will build upon its deep space habitat concept it developed during the first phase of NASA’s Next Space Technologies for Exploration Partnerships, or NextSTEP, program by using virtual and augmented reality prototyping in an effort to reduce costs and schedule, as well as identify and address issues while early in the design process. The results, to be shared with the space agency, will help to further understanding of the systems, standards and interfaces needed to make living in deep space possible.
This is nice, but it is essentially make-work for Lockheed Martin and a waste of money. At this stage of our engineering knowledge, we need to fly our interplanetary spaceship prototypes. Building them on the ground can only provide a limited amount of new knowledge, much of which has already been learned from numerous very similar past ground-based experiments.
For example, why isn’t NASA and Lockheed Martin also partnering with SpaceX, contracting to fly Donatello on the Falcon Heavy? That makes a lot more sense, and would not cost a lot of additional money. In fact, it might be quite cheap, since SpaceX needs customers willing to gamble on its new heavy-lift rocket.
Due to an accident during satellite launch preparations, NASA and Boeing are planning to replace a damaged antenna on NASA’s TDRS-M satellite, used by NASA mainly for communications between the ground and ISS.
The update at the link however says nothing whether the satellite will still launch on August 3, as presently scheduled. Nor have they released any information about the accident itself.
Capitalism in space: Sierra Nevada has awarded ULA the contract for the first two cargo flights of Dream Chaser to ISS.
The announcement sets Dream Chaser’s first cargo flight to the International Space Station for launch from Cape Canaveral Air Force Station, Florida, in 2020. A second ISS cargo flight is contracted to lift off the next year. “ULA is an important player in the market and we appreciate their history and continued contributions to space flights and are pleased to support the aerospace community in Colorado and Alabama,” said Mark Sirangelo, corporate vice president of SNC’s Space Systems.
Financial terms of the contract were not disclosed.
A NASA TDRS communications satellite, scheduled for a August 3 launch on a ULA Atlas 5 rocket, was damaged on July 14 while it was undergoing final preparations for launch.
Though the issue apparently involves one of the satellite’s main antennas, it is unclear what happened exactly or how extensive the damage was. Furthermore, this article about the incident notes that an earlier incident had also occurred during shipping.
It is understood this latest incident is not related to a ‘close call’ that NASA was investigating earlier in the flow. That incident involved the spacecraft’s shipping container – containing environmental instrumentation – which slid a couple of feet on the trailer it was being winched on to.
If I was a customer who might want to buy the launch services of ULA, I would demand detailed information about why these incidents happened, including what measures are being taken to prevent them from occurring again.
The Trump administration today announced that Scott Pace will be the executive secretary of the National Space Council, headed by Vice-President Mike Pence.
Some might immediately think I will be upset by this choice, as Pace wrote a critical and what I consider to be a weak review of my policy paper, Capitalism in Space. This however is not true. We might have disagreed on some points, but I think that Pace might be an ideal choice. He has the ear and the support of the big government space companies, but also understands the need to let private enterprise run things more, a point he himself expressed in his review of my policy paper. As Dr. David Livingston of The Space Show wrote me today in an email,
Pace was the deputy administrator when Mike Griffin formed COTS which has turned out to be a pillar program for the emerging commercial space industry. I also know Scott is grounded well in economics, policy, and realism. He is politically savvy as well and that expertise will be needed to move policy and constructive programs forward.
Pace’s connections with the contractors who have been building SLS/Orion for decades are of course a concern, but his connections with COTS is cause for celebration. We can only wait and see where this goes.
The squealing of pigs: The House appropriations committee yesterday approved the budgets for both NASA and NOAA, essentially accepting the budget numbers approved by its subcommittee.
Overall, the House increased spending over the Trump administration’s proposed cuts. Only in the area of climate did the legislators appear to support those cuts, and even here they pumped more money in.
The Trump Administration proposed a deep cut to [NOAA’s Polar Follow-On mission] saying it will re-plan the program ($180 million instead of the $586 million NOAA said last year it would need for FY2018). The committee went even further, approving only $50 million, but added it would reconsider if NOAA provides a better explanation of how it is restructuring the program. NOAA’s plans for new space weather satellites also fell far short of what the agency planned last year, although the committee provided more ($8.5 million) than the Trump Administration requested ($500,000).
In general, do not expect this Republican Congress to gain any control over the federal deficit. They are as spendthrift as Democrats. The only difference is their choice of programs.
