[/caption]The current buzz amongst those in the know say that astrophysicist/astronaut, John Grunsfeld, has been chosen to lead NASA’s science mission directorate. Self-confessed “Hubble Hugger” and telescope repair man may very well become NASA associate administrator in September, according to a news article in Nature. As current deputy director of the Space Telescope Science Institute in Baltimore, Maryland, Grunsfeld will be replacing the resigning Ed Weiler.
“John is a very capable guy,” Weiler was quoted by writer Eric Hand in Nature. “He knows both the human and robotic sides. He’s a very solid citizen.”
However, NASA spokesman Trent Perrotto says no appointment has yet been made official.
Nature reports that the five-time shuttle astronaut could likely be the top choice of NASA administrator Charles Bolden, also a former shuttle pilot, and may display just a bit of favoritism towards fellow astronauts. “Clearly, he’s Charlie’s pick,” says one person with knowledge of the selection.
But Nature quotes another science source that Grunsfeld might not be the right pick. Apparently he/she believes that NASA-backed scientists who aren’t part of the astronomy field shouldn’t be a prime candidate. “His entire reputation is based on fixing space telescopes,” says the scientist. “I think it will be a real tough slog for him.”
This afternoon the U.S. Senate approved H.R. 2112, a FY 2012 bill from Maryland Senator Barbara Mikulski that would fund the James Webb Space Telescope to launch in 2018. This is another step forward for the next-generation space telescope, which many have called the successor to Hubble… all that now remains is for the House to reconcile.
“We are creating the building blocks that we need for a smarter America. Our nation is in an amazing race – the race for discovery and new knowledge, the race to remain competitive,” Chairwoman Mikulski said. “This bill includes full funding of the James Webb Telescope to achieve a 2018 launch. The Webb Telescope supports 1,200 jobs and will lead to the kind of innovation and discovery that have made America great. It will inspire America’s next generation of scientists and innovators that will have the new ideas that lead to new products and new jobs.”
The bill was approved by a vote of 69 to 30.
Thanks to everyone who contacted their representatives in support of the JWST and to all the websites out there that helped make it simple to do so… and of course to all the state representatives who listened and stood behind the JWST!
In addition to continued funding for the telescope the 2012 bill also allots the National Aeronautics and Space Administration $17.9 billion (still a reduction of $509 million or 2.8 percent from the 2011 enacted level) and preserves NASA’s portfolio balanced among science, aeronautics, technology and human space flight investments, including the Orion Multipurpose Crew Vehicle, the heavy lift Space Launch System, and commercial crew development.
It also supports funding for the NOAA.

Of course, we must remember that spending and allocation of funds is not necessarily creating funds. As with everything, money has to come from somewhere and it remains to be seen how this will affect other programs within NASA. Not everyone is in agreement that this is the best course of action for the Administration at this point, not with the overall reduction of budget being what it is.
Do you love astronomy? Do you appreciate science? Do you have a curiosity about the nature of our Universe, how it came to be and what our place is within it? If you are even reading this I assume your answers to all of those questions is a resounding “yes!” and so I present to you an excellent video created by Brad Goodspeed in support of the James Webb Space Telescope:
“I made Vision because I thought the argument for science could benefit from a passionate delivery,” Brad told Universe Today. “Deep down we’re all moved by the stars, and that passion needs to be expressed by methods outside of science’s typical toolbox.”
Funding for this next-generation telescope is currently on the line in Washington. While a markup bill was passed last month by the House of Representatives that allows for continued funding of the JWST through to launch, it has not yet been ratified by Congress. It’s still very important to maintain support for the JWST by contacting your state representatives and letting them know that the future of space exploration is of concern to you.
A petition against the defunding of the JWST is currently active on Change.org and needs your signature (if you haven’t signed it already.) Signing ends at midnight tonight so be sure to click here to sign and pass it along as well! (You can share this shortened link on Twitter, Facebook, etc.: http://chn.ge/oy4ibI)
The JWST will be the premier observatory of the next decade, serving thousands of astronomers worldwide. It will study every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System. It is currently aiming for a 2018 launch date.
“We don’t get to the future by yielding to our most current fears… by being shortsighted.”
The 2012 fiscal year appropriation bill, marked up today by the Senate, allows for continued funding of the James Webb Space Telescope and support up to a launch in 2018! Yes, it looks like this bird is going to fly.

It will study every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System. JWST will be a large infrared telescope with a 6.5-meter primary mirror.
Thanks to everyone who contacted their representatives and expressed their support of the JWST, to all the websites out there that made it particularly simple to do so, and of course to all the state representatives who stood behind the program and didn’t allow it to get mothballed. The space science community thanks you and the current and future generations of astronomers, physicists, cosmologists and explorers thank you.
“In a spending bill that has less to spend, we naturally focus on the cuts and the things we can’t do. But I’d like to focus on what we can do. The bill invests more than $12 billion in scientific research and high impact research and technology development, to create new products and new jobs for the future.”

In addition to continued funding for the telescope the 2012 bill also allots the National Aeronautics and Space Administration $17.9 billion (a reduction of $509 million or 2.8 percent from the 2011 enacted level) and preserves NASA’s portfolio balanced among science, aeronautics, technology and human space flight investments, including the Orion Multipurpose Crew Vehicle, the heavy lift Space Launch System, and commercial crew development.
In this tighter economy, all of the agencies funded under the bill are also called on to be better stewards of taxpayers’ dollars, and waste and overspending will be much more closely monitored.
NOTE: While the JWST program has been specifically included in today’s markup, the bill itself still needs to be approved by the full appropriations committee and then go to the Senate floor for a vote. It then must be reconciled with the House version before receiving final appropriation. Still, this is definitely one step closer to getting the JWST off the ground! Read more on ScienceInsider here.
Writing a dictionary is not the same as writing a novel. While it might seem difficult to mess up a dictionary, even one with terminology that is as complicated as that used within the space industry – getting it right can be challenging. For those that follow space flight having such a dictionary can be invaluable. While A Dictionary of the Space Age does meet the basic requirements easily it fails somewhat in terms of its comprehensiveness.
When normal folks, even space enthusiasts watch launches and other space-related events (EVAs, dockings, landings and such) there are so many acronyms and jargon thrown about – that it is extremely hard to follow. With A Dictionary of the Space Age on hand, one can simply thumb through and find out exactly what is being said, making it both easier to follow along and making the endeavor being witnessed far more inclusive. That is as long if you are only looking for the most general of terms. The book is far from complete – but given the complex nature of the topic – this might not have been possible.
Crewed, unmanned, military space efforts and satellites – all have key terms addressed within the pages of this book.
The book is published by The Johns Hopkins University Press and was compiled and written by aerospace expert Paul Dickson. One can purchase the book on the secondary market (Amazon.com) for around $12 (new for around $25). The dictionary also has a Kindle edition which is available for $37.76. Dickson’s previous works on space flight is Sputnik: The Shock of the Century.
Weighing in at 288 pages, the book briefly covers the primary terms used within the space community. In short, if you are interested in learning more about space flight – or wish to do so – this is a good book for you.
The James Webb Space Telescope or JWST has long been touted as the replacement for the Hubble Space Telescope. The telescope is considered to be the one of the most ambitious space science projects ever undertaken – this complexity may be its downfall. Cost overruns now threaten the project with cancellation. Despite these challenges, the telescope is getting closer to completion. As it stands now, the telescope has served as a technical classroom on the intricacies involved with such a complex project. It has also served to develop new technologies that are used by average citizens in their daily lives.
Although compared to Hubble, the two telescopes are dissimilar in a number of ways. The JWST is three times as powerful as Hubble in its infrared capabilities. JWST’s primary mirror is 21.3 feet across (this provides about seven times the amount of collecting power that Hubble currently employs).
The JWST’s mirrors were polished using computer modeling guides that allowed engineers to predict that they will enter into the proper alignment when in space. Each of the mirrors on the JWST has been smoothed down to within 1/1000th the thickness of a human hair. The JWST traveled to points across the country to assemble and test the JWST’s various components.
Eventually the mirrors were then sent to NASA’s Marshall Space Flight Center in Huntsville, Alabama. Once there they measured how the mirrors reacted at extremely cold temperatures. With these tests complete, the mirrors were given a thin layer of gold. Gold is very efficient when it comes to reflecting light in the infrared spectrum toward the JWST’s sensors.
The telescope’s array of mirrors is comprised of beryllium, which produces a lightweight and more stable form of glass. The JWST requires lightweight yet strong mirrors so that they can retain their shape in the extreme environment of space. These mirrors have to be able to function perfectly in temperatures reaching minus 370 degrees Fahrenheit.
After all of this is done, still more tests await the telescope. It will be placed into the same vacuum chamber that tested the Apollo spacecraft before they were sent on their historic mission’s to the moon. This will ensure that the telescopes optics will function properly in a vacuum.
With all of the effort placed into the JWST – a lot of spinoff technology was developed that saw its way into the lives of the general populace. Several of these – had to be invented prior to the start of the JWST program.
“Ten technologies that are required for JWST to function did not exist when the project was first planned, and all have been successfully achieved. These include both near and mid-infrared detectors with unprecedented sensitivity, the sunshield material, the primary mirror segment assembly, the NIRSpec microshutter array, the MIRI cryo-cooler, and several more,” said the James Webb Space Telescope’s Deputy Project Scientist Jason Kalirai. Kalirai holds a PhD in astrophysics and carries out research for the Space Telescope Science Institute. “The new technologies in JWST have led to many spinoffs, including the production of new electric motors that outperform common gear boxes, design for high precision optical elements for cameras and cell phones, and more accurate measurements of human vision for people about to undergo Laser Refractive Surgery.”
If all goes according to plan, the James Webb Space Telescope will be launched from French Guiana atop the European Space Agency’s Arianne V Rocket. The rationale behind the Ariane V’s selection was based on capabilities – and economics.
“The Ariane V was chosen as the launch vehicle for JWST at the time because there was no U.S. rocket with the required lift capacity,” Kalirai said. “Even today, the Ariane V is a better tested vehicle. Moreover, the Ariane is provided at no cost by the Europeans while we would have had to pay for a U.S. rocket.”
It still remains to be seen as to whether or not the JWST will even fly. As of July 6 of this year the project is slated to be cancelled by the United States Congress. The James Webb Space Telescope was initially estimated at costing $1.6 billion. As of this writing an estimated $3 billion has been spent on the project and it is has been estimated that the telescope is about three-quarters complete.
