Webb successfully launched

8:13 am

Early this morning an Ariane 5 rocket successfully launched the James Webb Space Telescope from French Guiana.

The key moment that indicated the launch was success was, after Webb was deployed from the rocket’s upper stage, its solar panels deployed and the telescope began receiving power from them.

The launch itself was something that has been done by the Ariane 5 rocket many many times, without failure. Now comes the part of this operation that has never been done before.

Now “30 days of terror” begin, as JWST starts its career in space. First, it will take the space telescope 30 days to reach the start of its halo orbit at L2. On its way, the telescope must unfurl its 18 gold-plated beryllium mirror segments using 132 actuators. It will also have to deploy its five-layer, origami sunshield and cool down to below 50K (-223°C or -370°F) to begin the start of science operations in 2022.

NASA has a webpage that shows the step-by-step deployment, and allows you to see the status at any time during the next 30 days.

After almost twenty years of development and a budget that went 20x over its original estimate, let’s us all hope that Webb deploys properly and begins collecting data as intended. If it does, it will allow astronomers to make ground-breaking discoveries, and we shall gain a better idea of what lies hidden behind that black sky that surrounds us.

As for the 2021 launch race, this is the updated leader board:

49 China
31 SpaceX
22 Russia
7 Europe (Arianespace)

China will likely be the winner in the national rankings, 49 to 48 over the U.S. This was the 130th successful launch in 2021, only the second time in the history of space exploration that the world reached that number of launches in a single year.

Webb telescope reaches launchpad on Ariane 5 + how to watch launch

9:14 am

The James Webb Space Telescope, stacked on top of Arianespace’s Ariane 5 rocket, has finally reached its launchpad in French Guiana after twenty years of development costing 20 times its original budget.

The launch itself is now scheduled for December 25, 2021 at 7:20 am (Eastern). It will be live streamed by both NASA (in English) and Arianespace (with options in English, French, or Spanish).

I have embedded below NASA’s feed. As always, expect NASA to pump you with lots of propaganda during its live stream.

When all is said and done, Webb has the chance to show us things about the universe we’ve never seen before. Optimized for deep space cosmology, it will provide us a window into the earliest moments of the universe’s existence. And is infrared capabilities will allow it to peer into many nearer places obscured by dust with a resolution unmatched by previous telescopes.

Keep your fingers crossed all goes as planned.

ESA delays Webb launch one day due to weather

8:41 am

The European Space Agency (ESA) announced late yesterday that, due to “adverse weather conditions” in French Guiana, it has delayed the launch of the James Webb Space Telescope on an Ariane 5 rocket one day to December 25th.

The announcement also stated that the final launch readiness review also approved the launch, though no update has yet been issued on the ground control communications problem that had caused a two day delay last week.

Meanwhile, this story and its headline encapsulates the terror I think many astronomers presently feel about this telescope:

Why Astronomers Are “Crying and Throwing Up Everywhere” Over the Upcoming Telescope Launch

The sense is one of helpless panic among astronomers who want to use Webb. They know it will do really cutting edge science, but they also know that many things can go wrong, and the history of the telescope (ten years late and 20x overbudget) will likely make replacing it impossible.

And many things can go wrong. Below is NASA’s video showing the telescope’s complex unfolding, step-by-step, after launch.

Webb launch confirmed for December 24, 2021

9:01 am

Ten years late and twenty times over budget the European Space Agency (ESA) yesterday confirmed that the launch of NASA’s infrared James Webb Space Telescope is now scheduled for December 24, 2021.

The ESA announcement is only a couple of sentences long, and does not mention if engineers had solved the intermittent ground communications issue with the telescope. Further tweets from ESA and NASA also said nothing about the communication issue.

A final readiness review is set for December 21st where a final launch decision will be made.

Webb launch delayed two days because of ground equipment issue

9:42 pm

After engineers at Arianespace’s French Guiana launch facility found an intermittent issue with ground equipment related to the Ariane 5 rocket launching the James Webb Space Telescope, it was decided to delay the launch two days to make sure the problem was resolved.

n a brief statement, NASA wrote on its website late Tuesday that the Webb team is “working a communications issue between the observatory and the launch vehicle system.”

Thomas Zurbuchen, associate administrator for NASA’s science mission directorate, said Tuesday that engineers found an “interface problem” in a system that communicates with Webb while it’s on top of the Ariane 5 rocket. “The way to think about it is it’s a ground support equipment thing,” Zurbuchen said Tuesday night in an interview with Spaceflight Now. “Basically, the data cables are dropping some frames.”

Technicians inside the Ariane 5 rocket’s final assembly building in Kourou have tried to diagnose the problem, but so far, haven’t been able to resolve it.

The December 24th target day date remains tentative, and could slip to December 25th, or even later, depending on how successful engineers are at fixing the issue.

Engineers: Webb undamaged by “incident”, ready for December 22nd launch

9:46 am

Arianespace engineers have confirmed after testing that the James Webb Space Telescope was undamaged by “incident” that occurred during stacking, and have okayed the resumption of the telescope’s preparation for launch.

On Wednesday, Nov. 24, engineering teams completed these tests, and a NASA-led anomaly review board concluded no observatory components were damaged in the incident. A “consent to fuel” review was held, and NASA gave approval to begin fueling the observatory. Fueling operations will begin Thursday, Nov. 25, and will take about 10 days.

The launch is now set for December 22nd.

Webb launch delayed four days because of “incident” during stacking

2:18 pm

NASA management has decided to delay the launch of the James Webb Space Telescope for four days while engineers investigate whether an “incident” that occurred during the telescope’s stacking on top of an Ariane 5 rocket could have long term consequences.

Technicians were preparing to attach Webb to the launch vehicle adapter, which is used to integrate the observatory with the upper stage of the Ariane 5 rocket. A sudden, unplanned release of a clamp band – which secures Webb to the launch vehicle adapter – caused a vibration throughout the observatory.

A NASA-led anomaly review board was immediately convened to investigate and instituted additional testing to determine with certainty the incident did not damage any components. NASA and its mission partners will provide an update when the testing is completed at the end of this week.

The launch had been scheduled for December 18th. They have now pushed it back to December 22nd.

Next Ariane 5 launch postponed

11:39 am

Arianespace today announced that it has postponed its next Ariane 5 launch of two communications satellites, scheduled for October 22nd, because of issues with ground equipment.

Though there appear to be no issues with the rocket, this delay could effect the launch of the James Webb Space Telescope in December on another Ariane 5 rocket. Arianespace has said that it wants to complete this launch first, to make sure the fixes it completed on the rocket’s fairing are truly working.

It was those problems that shut down all Ariane 5 launches for almost a full year.

No new launch date has been set. Normally, ground equipment issues cause short delays, so we should be hopeful all will be fixed quickly and this launch will be quickly rescheduled and take off without problems.

Webb telescope finally arrives at launch site in French Guiana

2:54 pm

Webb deployment

After almost twenty years of construction (a decade behind schedule) and a cost of $10 billion, ($9.5 billion over budget), the James Webb Space Telescope today arrived at the processing facility at Arianespace’s French Guiana spaceport, where it will be prepared for a December 18, 2021 launch on an Ariane 5 rocket.

Once launched the telescope, which is not a replacement for Hubble because it observes in the infrared (not optical) and is optimized for deep space cosmology, will take two weeks to reach its orbital position about a million miles from Earth, as shown in the graphic.

Let us all cross our fingers and toes that it all works as designed, for if it doesn’t this will be the biggest failure ever in the history of NASA.

NASA now targets December 18, 2021 for launch of Webb

1:12 pm

NASA today announced that it and the European Space Agency have scheduled the Ariane 5 launch of the James Webb Space Telescope from French Guiana for December 18, 2021.

The agency set the new target launch date in coordination with Arianespace after Webb recently and successfully completed its rigorous testing regimen – a major turning point for the mission. The new date also follows Arianespace successfully launching an Ariane 5 rocket in late July and scheduling a launch that will precede Webb. The July launch was the first for an Ariane 5 since August 2020.

Launching before the end of ’21 will allow NASA to claim that Webb is only be ten years behind schedule, not eleven. The cost overruns however remain astronomical (no pun intended). Initially budgeted at $500 million, Webb is now estimated to have cost $10 billion.

Once launched the telescope will take about six months to slowly move to its Lagrange point location about a million miles from the Earth, in the Earth’s shadow. During that time it will also be steadily deploying its many segmented mirror for infrared observations (an important detail as Webb is not a replacement for Hubble, which does most of its observations in the optical wavelengths).

Should deployment and placement go as planned, Webb will undoubtedly do ground-breaking astronomy, especially in the field of deep space cosmology. If anything should go wrong, any repair mission will take at a minimum five years to mount, if ever.

Keep those fingers and toes crossed!

Webb telescope finally completed, ready for shipment to launchpad

2:15 pm

After more than two decades of construction (ten years behind schedule) and more than $10 billion (20 times the original cost), the infrared James Webb Space Telescope has finally completed its testing and is ready for shipment to its launch site in French Guiana to be mounted on an Ariane 5 rocket.

Now that observatory testing has concluded, shipment operations have begun. This includes all the necessary steps to prepare Webb for a safe journey through the Panama Canal to its launch location in Kourou, French Guiana, on the northeastern coast of South America. Since no more large-scale testing is required, Webb’s clean room technicians have shifted their focus from demonstrating it can survive the harsh conditions of launch and work in orbit, to making sure it will safely arrive at the launch pad. Webb’s contamination control technicians, transport engineers, and logistics task forces are all expertly prepared to handle the unique task of getting Webb to the launch site. Shipping preparations will be completed in September.

If all goes well, NASA and ESA hope to launch the telescope in late October. It will then take about six months for the telescope to unfold and reach its operating position a million miles from Earth in the Earth’s shadow.

Let us all pray that everything works. If it does not, there will be nothing that can be done to fix it for probably at least five years, if then, as it will be out of reach of any maintenance mission, manned or unmanned.

Problem with Ariane 5 rocket causes Arianespace to delay Webb telescope launch

9:08 am

As first revealed in mid-May, Arianespace has been forced to delay the launch of the James Webb Space Telescope by at least one month because of a problem with the fairing on its Ariane 5 rocket, found during an August 2020 launch.

There have been no Ariane 5 launches since. According to yesterday’s press briefing, however:

“The origin of the problem has been found. Corrective actions have been taken,” Daniel de Chambure, acting head of Ariane 5 adaptations and future missions at ESA, said. “The qualification review has started, so we should be able to confirm all that within a few days or weeks.” He did not elaborate on the problem or those corrective actions, beyond stating that the problem took place during separation of the payload fairing. Industry sources said in May that, on the two launches, the separation system imparted vibrations on the payload above acceptable limits, but did not damage the payloads.

It appears this new delay to Webb’s launch is because two commercial payloads must lift off first before Webb, with the first now scheduled for July. According to Arianespace, it will take two months prep for the next commercial launch, followed by two months prep for the Webb launch. That puts the launch of Webb in November.

Overall this particular delay is slight, only a few weeks, and pales in comparison to the ten years of delays experienced by NASA during development and construction of Webb. It also will add very little to the telescope’s overall budget, which has grown from an original price of $500 million to now about $10 billion.

GAO finds more NASA cost overruns in Webb, SLS, and Orion

2:18 pm

GAO graph documenting NASA's big project delays and cost overruns

The annual Government Accountability Office’s (GAO) report on major NASA-led programs has found that the cost overruns and scheduling problems it has documented now for years continued in 2020.

You can obtain the report here. The graph to the left, from the report, summarizes the data quite succinctly.

The cumulative cost overrun of 20 major programs in development, defined as those with total costs of at least $250 million, grew to more than $9.6 billion in the report. Three programs — the James Webb Space Telescope, Orion spacecraft and Space Launch System — account for $8 billion of that total, including $4.4 billion for JWST alone.

SLS and the Exploration Ground Systems program accounted for effectively all of the $1.1 billion in overruns in 2020. … SLS alone accounted for nearly $990 million in cost increases. About two-thirds of that increase came from NASA adopting a GAO recommendation to lower the original baseline cost estimate for SLS to properly account for work that had been shifted to later phases of the program.

The report also documented almost 20 years of cumulative delays, with Webb leading the way with delays of more than seven years. The new report added 37 more months of delays during the last year.

The report, and NASA, laid the blame for many of the more recent delays and cost overruns on last year’s COVID epidemic, but if so those delays were imposed by choice, not necessity, considering how both China and SpaceX moved forward without any delays during the same time period. In reporting on NASA for the last three decades I have found it willing to initiate long delays at the drop of a hat, sometimes for reasons, such as a storm that causes some minor damage, that do not justify either the delay or its length. The COVID panic was just another example of this.

More delays for Webb telescope?

8:53 am

An issue with the fairing release on the last two Ariane 5 launches has not only paused use of that rocket since August 2020, it might cause another delay in the planned October 31, 2021 launch of the James Webb Space Telescope.

In a statement to SpaceNews, Arianespace acknowledged that “post-flight analyses conducted on two recent Ariane 5 launches have indicated the occurrence of a less than fully nominal separation of the fairing, however with no adverse impact on the Ariane 5 flights in question.”

The company did not elaborate on the problem, but industry sources familiar with the issue said that, on both the August 2020 launch and the previous Ariane launch in February 2020, the separation of the faring induced vibrations into the payload stack well above acceptable limits. Neither incident damaged any of the payloads, but raised concerns about the effect on future missions, including JWST.

Moreover, Arianespace has two Ariane 5 launches on its schedule that are supposed to launch before Webb. If those are delayed it puts a further squeeze on the Webb launch date.

Meanwhile, the final checkouts of the Webb telescope have been proceeding, including a successful test of the unfolding of the telescope’s segmented mirror.

After a more than decade of delays and budget overruns — raising this telescope’s budget from 1/2 billion to $10 billion — it appears that Webb’s final schedule delay might occur not because of the telescope but because of the rocket.

In addition, the issue at Arianespace appears to be seriously impacting that company’s ’21 launch schedule, having failed to launch any Ariane 5 rockets so far this year.

NASA confident Webb will launch in October

9:36 am

In a briefing held yesterday, NASA officials — in summarizing the status of the James Webb Space Telescope — stated they were presently confident that its launch will take place in October this year, as presently planned.

[Eric Smith, JWST program scientist> said the program is dealing with one new technical issue. Two communications transponders suffered separate problems during testing in January. Engineers have tracked down the problems with the two units and started repairs this week. “Those boxes will be back in time for us to make our planned shipping date,” he said.

That issue, he acknowledged, will use some of the remaining schedule margin. “The plan right now is that we’ll get them back in time so that we don’t have to use all of it,” he said. “That’s the main thing that we’re watching regarding the margin.”

If launched in October, Webb will only be a decade behind schedule and a mere 20 times over budget, having been initially proposed to launch in 2011 for a cost of $500 million. Instead, it will cost about $10 billion.

The article also notes that the Biden administration might change the telescope’s name because Webb as a bureaucrat early in his career apparently publicly opposed homosexual rights. Such opinions can no longer be allowed, and anyone who has them must be blackballed as quickly as possible.

No matter. Webb was merely NASA’s administrator through almost its entire first decade, leading the agency in its triumph over the Soviets in the race to the Moon. Such achievements cannot be honored as they illustrate the past greatness of America. Moreover, Webb was a white man, and this makes him totally unqualified to receive any laurels. Today’s modern America hates itself and all white men.

The article also notes a variety of issues that will cause more delays of the new big astronomy boondoggle at NASA, the Roman Space Telescope. They say its launch will likely be delayed to 2026 because of the Wuhan flu panic. I predict this is only a foretaste. Expect many more delays and budget overruns, probably pushing its launch into the 2030s.

But no matter. What is really important is that this new boondoggle is named for a woman!

NASA confirms Webb launch delay to October 2021

2:12 pm

NASA today confirmed that the launch date of the James Webb Space Telescope will be delayed again, from March 2021 to October 2021.

As schedule margins grew tighter last fall, the agency planned to assess the progress of the project in April. This assessment was postponed due to the pandemic and was completed this week. The factors contributing to the decision to move the launch date include the impacts of augmented safety precautions, reduced on-site personnel, disruption to shift work, and other technical challenges. Webb will use existing program funding to stay within its $8.8 billion development cost cap. [emphasis mine]

Note the highlighted words. Vague, eh? They are trying to make it seem that this new delay is solely because of the Wuhan virus panic, but that’s simply not justifiable. Notice how SpaceX has kept on launching Falcon 9s as well as testing new Starship prototypes throughout the panic. Somehow that private company was able keep its schedule going.

The truth is that as early as January, long before COVID-19 was even a blip on the horizon, the GAO was warning everyone that it was unlikely NASA and Northrop Grumman could meet the March 2021 launch date.

Webb is now more than a decade behind schedule, and once launched will have cost 20 times what it was originally budgeted ($500 million vs $10 billion). Let us pray that it works once it gets to is proper orbit, a million miles from Earth, since it will then be too far away to fix.

NASA confirms Webb launch delayed again

9:16 am

NASA officials yesterday confirmed that, due to the new work conditions and the lock down imposed by the Wuhan flu panic, the launch of the James Webb Space telescope will not occur in March 2021.

“We will not launch in March,” said Thomas Zurbuchen, the space agency’s associate administrator for science. “Absolutely we will not launch in March. That is not in the cards right now. That’s not because they did anything wrong. It’s not anyone’s fault or mismanagement.”

Zurbuchen made these comments at a virtual meeting of the National Academies’ Space Studies Board. He said the telescope was already cutting it close on its schedule before the COVID-19 pandemic struck the agency and that the virus had led to additional lost work time. “This team has stayed on its toes and pushed this telescope forward at the maximum speed possible,” he said. “But we’ve lost time. Instead of two shifts fully staffed, we could not do that for all the reasons that we talk about. Not everybody was available. There were positive cases here and there (in the surrounding area, not on site). And so, perhaps, we had only one shift.”

No new target date has been set, though the comments even hinted that they might not be able to do it in 2021.

Webb will cost 20 times more than originally budgeted ($500 million vs $10 billion) and is now more than a decade behind schedule. In the process, those overages and delays wiped out almost all of NASA’s other astronomy projects during the 2010s.

But don’t worry! Once Webb launches the task of wiping out more astronomy projects with overages and delays will be courageously taken up by NASA’s Roman Space Telescope (formerly WFIRST), already behind schedule and over budget, and it is still only in the design phase.

Webb telescope further delayed by COVID-19

10:38 am

As part of its decision to shut down most of the agency’s operations due to fear of the COVID-19 virus, NASA’s has suspended all work on the James Webb Telescope, further delaying this much delayed space telescope.

The follow-on to the popular Hubble Space Telescope [Ed: a NASA lie that is not true], years late and billions over budget, it was on track for launch in March 2021, though some NASA officials were hinting there might be another delay. Today’s action almost certainly assures it. “The James Webb Space Telescope team … is suspending integration and testing operations. Decisions could be adjusted as the situation continues to unfold over the weekend and into next week. The decision was made to ensure the safety of the workforce. The observatory remains safe in its cleanroom environment.” — NASA

I must repeat this incessantly, as it appears too many modern space reporters are very ignorant about their own field. Webb is not a” follow-on to Hubble.” Astronomers made the decision in the late 1990s to build an infrared space telescope instead, which is what Webb is. For more than a decade they, and NASA, lied to the public about this, claiming Webb was a better version of Hubble, in order to garner support for building Webb.

I have been calling NASA on lie this since 2008, when I wrote The Universe in a Mirror, which I think eventually forced the agency to stop doing it. It is shameful however for a reporter now, in 2020, to still spread it.

As for Webb, this decision by NASA will certainly delay it again. The project is already fourteen years behind schedule, with its budget ballooning from $500 million to about $10 billion. All told, a perfect example of government in action.

GAO warns of more Webb delays

8:47 am

The race to the bottom between Webb and SLS continues! A new Government Accountability Office (GAO) report warns that there is high likelihood that NASA will not meet its March 2021 target launch date for the James Webb Space Telescope.

The report noted that the program performed an updated joint confidence level analysis of the mission’s cost in schedule in October. “Because of schedule delays resulting from technical challenges coupled with remaining risks faced by the project, the analysis assessed only a 12 percent confidence level for the project’s ability to meet the March 2021 launch readiness date,” the report stated.

NASA missions usually set cost and schedule estimates at the 70% confidence level. Using that metric, the launch would likely take place in July 2021, a delay of four months, according to the report.

Webb is now more than a decade behind schedule, with its budget ballooning from $1 billion to just under $10 billion. These facts essentially wiped out almost all new astronomical projects in the 2010s.

Webb telescope remains on schedule for March 2021 launch

9:22 am

Good news: According to NASA and Northrop Grumman officials, the James Webb Space Telescope remains on schedule for its March 2021 launch by an Ariane 5 rocket.

This might be the first update on Webb in years where no new delays were announced. Instead, the Space Telescope Science Institute in Maryland, which will manage the telescope, is preparing to release in two weeks its first call for research proposals.

Proposals will be due May 1, with the institute making selections later in the summer. …[I]nstitute officials said they expect to receive 1,000 to 1,600 proposals, seeking some fraction of the 6,000 hours of observing time that will be available in that initial round of observations. About 300 proposals will be selected for Cycle 1, which will begin once spacecraft commissioning is complete about six months after launch.

Let us all pray that all goes well during launch and spacecraft deployment.
