Former NASA shuttle head outlines a pessimistic future for NASA expensive Space Launch System.
Continuing to develop programs in the same old ways, from my observations, will certainly lead to cancellation as government budgets are stretched thin.”
NASA and JPL have now stated that the government shutdown will not interfere with their promised support for India’s Mars Orbiter Mission.
Earlier reports had suggested that NASA’s Deep Space Network, used to communicate with planetary probes, would not be available because of the shutdown, and the mission would have to be delayed because of this.
Posted from Columbia, Maryland.
Because India depends on the American Deep Space communications network — mostly unavailable due to the government shutdown — the launch of its first Mars probe, set for October 28, might have to be delayed for two years.
This is unfortunate news indeed. However, if I was India (as well as other countries) I would consider this a call to develop their own deep space network.
NASA has decided to exempt its Mars probe, MAVEN, from the government shutdown, allowing preparations to resume for its November launch.
NASA Headquarters in Washington determined that Maven’s preparations should go ahead on an emergency basis — not because of its scientific objectives, but because of its expected role as a communications relay satellite for the Opportunity and Curiosity rovers on Mars. “Both Mars Reconnaissance Orbiter and Odyssey have been acting as communication relays, but they’ve passed their design lifetime,” Jakosky explained. “Maven carries communication equipment to take over that job as necessary. Getting us launched at this opportunity is a way to preserve that ability to communicate.”
As I’ve said before, as much as I am in favor of launching this kind of science mission, the number of arbitrary decisions relating to this shutdown makes the whole thing look ridiculous. NASA can act to protect its investments on Mars, but the National Park Service is required to interfere with the normal actions of private restaurants here on Earth?
The truth is that these science missions really don’t fall under the intended definition of “essential operations”. The federal bureaucracy, under the direction of the White House, is simply stretching that definition for their own convenience, wherever they like.
NASA marches on! After developing the J-2X engine for the upper stage of its SLS heavy-lift rocket, NASA now plans to mothball it.
While the agency is actively seeking other missions for the heavy-lift Space Launch System (SLS) in the planetary science and military arenas, most of the human flights it has in sight for the big new rocket probably can be accomplished with an upper stage powered by the RL-10 engine instead of the J-2X. “The J-2X for certain [design reference missions] is somewhat overpowered,” said Todd May, NASA’s SLS program manager.
The main cause of this absurd situation is Congress, which has micro-managed the development of SLS from day one.
Chicken Little report: With a launch window from November 18 to December7, the government shutdown might delay NASA’s next Mars unmanned probe MAVEN until 2016.
It is absolutely possible that the shutdown could cause MAVEN to miss its launch window. Such is life. The world won’t end, and as much as I am a big supporter of space exploration, I also recognize that there are actually bigger issues than NASA hanging in the balance.
Note that the article above bleeds tears for the poor government officials who might not get paid during the shutdown. Well, the economy has sucked for the past five years, with no signs of improvement and plenty of evidence that Obama and Congress have done a great deal to make things worse, especially with the passage of Obamacare. Maybe we should instead have some sympathy for the people who earn the money to pay for NASA and the government and have been screaming at these politicians to just leave them alone.
NASA has released more details about Sunday’s schedule of Cygnus’s rendezvous and berthing with ISS.
Orbital Sciences is now aiming for a Sunday berthing of Cygnus to ISS.
SpaceX will delay its planned December launch of Dragon to ISS in order to complete upgrades to the capsule.
It was already expected that this December launch would be delayed anyway because NASA wants SpaceX to complete two launches of the upgraded Falcon 9 rocket before using it to launch Dragon to ISS.
The first and second launch of the Space Launch System are likely to be delayed due to budget issues.
“It’s very clear that we could have slips of a year or two,” said [deputy administrator Lori] Garver, referring to both the 2017 launch — which won’t have a crew — and the first planned flight of NASA astronauts aboard the SLS rocket in 2021.
Garver claims that it is insufficient funds for SLS that will cause the delays, despite getting $3 billion per year, or ten times the money the private commercial program is getting.
I’m on a hike today, but so any additional comments about this insanity will have to wait.
The competition heats up: The Russians are including a bathroom in their next generation manned vehicle, something they note Orion will not have.
A new Russian spaceship for trips to the moon or the International Space Station will have at least one crucial advantage over its American rival – a toilet, one of the craft’s developers said Friday. “I don’t think I need to elaborate on how a waste-collection system is much more comfortable than the diapers that astronauts aboard the [US spacecraft] Orion will have to use,” said Vladimir Pirozhkov of the Moscow Institute of Steel and Alloys, which is involved in the development of the Russian ship. “Besides, the Russian segment of the International Space Station [ISS] has a limited number of toilets, which means a spacecraft with an extra ‘space toilet’ will come in handy,” he added.
As much as I am skeptical of Orion and SLS, I am equally skeptical of the Russian claims of a next generation manned spacecraft. They have been unveiling these proposals now for more than a decade, with nothing ever getting built. With Orion we at least have an existing capsule, even if its bulkhead needed to fixed.
Though I will agree with them on one point: Putting a toilet on a vehicle intended to go beyond Earth orbit, which Orion is supposed to be designed to do, makes common sense. That NASA didn’t include this essential item in Orion reveals to us the unseriousness of the spacecraft.
A engineering problem during construction of one of the shuttle-derived solid rocket boosters for SLS is causing delays.
[The] original test target of mid-2013 slipped when an issue with the aft segment [of the booster] was found. Inspection of the segment showed it was contained an area where propellant had debonded from the inside of the segment wall. Following analysis – which notably found no voids in the propellant itself – NASA decided to ask ATK to scrap the segment and cast a replacement.
Preparations … continued, with the shipping and integration of forward and center segments at the test site, while ATK went to work to replace the aft segment, following approval – post investigation – from NASA’s Marshall Space Flight Center. After ATK successfully cast the replacement segment in July, technicians carried out routine ultrasound and x-ray tests. Unfortunately, the tests showed this segment had also had similar voids. [emphasis mine.]
The Space Launch System (SLS), was mandated by Congress to use as much shuttle-derived components as possible in order to supposedly save money as well as employ as many of the companies that built those components as possible. In reality, however, every one of those components has required significant redesign to make them work in SLS. In the case of the solid rocket boosters, the four segment shuttle boosters were not powerful enough. They had to be expanded to five segments.
Moreover, it appears from this article it was other technically unnecessary changes to the boosters that are now causing this problem.
