Engineers worked meticulously to implant the James Webb Space Telescope’s Mid-Infrared Instrument into the ISIM, or Integrated Science Instrument Module, in the cleanroom at NASA’s Goddard Space Flight Center in Greenbelt, Md. As the successor to NASA’s Hubble Space Telescope, the Webb telescope will be the most effective space telescope ever built. It will observe the most distant objects in the universe, offer images of the first galaxies formed and see unexplored planets around distant stars.

SMC Pentax M Zoom 75-150mm 1:4
precision engineering
Image by Yumi Abe
&quotWhat a strange lens !

Mechanically it is a piece of really clever engineering. It is a push-pull zoom, but the lens does not truly extend at all more than its focal range. In common with most of the M series lenses it is beautifully built, exuding solidity and precision. The aperture ring has precise half stop detents. Subsequent comes the wide zoom/concentrate ring. This is uncommon in that 150mm is set with the ring nearest to the camera finish. The zoom/focus is nicely damped, just stiff enough to decrease any zoom creep. The front of the lens extends slightly at short concentrate distance and rotates when focusing. A short built-in sliding hood completes the design and style.

The general look and really feel is of a really heavy, ‘long and thin’ telephoto lens. It is truly not that extended, about the identical length as the DA50-200. The concentrate travel angle is fairly brief at about 120 degrees or much less, just a bit also short for actually precise focusing. Similarly, the aperture clicks are fairly closely spaced. The zoom travel is also brief, at about 2 cm. However, in use it handles well, greater than some other push-pull zooms of that era.

On APS sensor camera it is optically sharp even at f4 over most of the focal variety and becomes quite sharp when stopped down a couple of clicks. There is no geometric distortion to speak of and really small chromatic aberration. There can be just a touch of purple fringing in higher contrast areas. Bokeh is not negative, possibly slightly on the ‘busy’ side – the aperture has only six blades. All round contrast is affordable, contemplating that there are 12 glass elements in the way. Colour is slightly on the cool side.

In its day, on a full frame camera, it would have been a fine portrait zoom lens.

There is however anything not quite appropriate with this lens when employed on a DSLR, such as my K-7. Somehow the shots lack ‘bite’, requiring a fair bit of post-processing contrast tweaking. It is hard to tell whether it is a lack of microcontrast, flare, shortage of pixie dust or some thing else. I suspect that there is just as well considerably glass in the way.

Well, obtaining taken it out on a sunny day with plenty of contrasty light, I have changed my opinion of this lens. It is really extremely sharp and it appears to like a lot of harsh light – as long as you do not let it shine on the front element. Shoot from the shade into the sunlight and it genuinely starts to execute, as it the last 3 shots under.

Becoming an all-manual lens the aperture and focal length are not recorded. The shots beneath were taken largely at f4 (or possibly f5.6) and ‘various’ focal lengths.&quot

Sunderland has a remarkable history of innovation in shipbuilding and marine engineering. From the improvement of turret ships in the 1890s and the production of Doxford opposed piston engines following the Initial Planet War via to the styles for Liberty ships in the 1940s and SD14s in the 1960s. Sunderland has much to be proud of.

Tyne &amp Put on Archives cares for tens of thousands of photographs in its shipbuilding collections. Most of these concentrate on the ships – in distinct their construction, launch and sea trials. This set looks to redress the balance and to celebrate the perform of the males and women who have played such a important element in the region’s history. The pictures show the human side of this great story, with several relating to the globe popular shipbuilding and engineering firm William Doxford &amp Sons Ltd.

The Archives has developed a brief weblog to accompany these pictures.

Chamber A
precision engineering
Image by James Webb Space Telescope
NASA’s &quotChamber A&quot thermal vacuum testing chamber well-known for getting utilized in the course of Apollo missions has now been upgraded and remodeled to accommodate testing the James Webb Space Telescope.

When the next-generation space telescope was getting made, engineers had to make certain there was a place large sufficient to test it, thinking about it’s as massive as a tennis court. That honor fell upon the renowned &quotChamber A&quot in the thermal-vacuum test facility at NASA’s Johnson Space Center in Houston, Texas.

Chamber A is now the biggest high-vacuum, cryogenic-optical test chamber in the globe, and made renowned for testing the space capsules for NASA’s Apollo mission, with and without having the mission crew. It is 55 feet (16.8 meters) in diameter by 90 feet (27.four meters) tall. The door weighs 40 tons and is opened and closed hydraulically.

For 3 years, NASA Johnson engineers have been creating and remodeling the chamber interior for the temperature needed to test the Webb. Testing will confirm the telescope and science instrument systems will carry out effectively collectively in the cold temperatures of space. Added test assistance gear consists of mass spectrometers, infrared cameras and television cameras so engineers can preserve an eye on the Webb whilst it really is becoming tested.

&quotSome of the issues we’ve completed is upgraded our helium technique, our liquid nitrogen system, and air flow management,&quot said Virginia Rivas-Yancy, project manager, Air Flow Management Program at NASA Johnson. Temperatures in Chamber A can now drop farther than ever — down to -439.9 Fahrenheit (-262.1 Celsius or 11 degrees Kelvin) which is 11 degrees above absolute zero.

&quotThe air in the chamber weighs 25 tons, about 12 1/2 Volkswagen Beetles when all the air is removed the mass left inside will be the equivalent of half of a staple,&quot stated Ryan Grogan, Webb Telescope Chamber A project engineer at NASA Johnson.

A very big clean area is also being ready close to Chamber A exactly where the observatory will be prepped for testing. The test itself will take 90 days. The 1st 30 days will consist of cooling the chamber down. The subsequent handful of weeks will incorporate tests on the Webb’s operating systems, and the remainder of the time will be spent warming up the chamber to area temperature.

Test articles are usually inserted into the chamber by implies of a precision mobile crane, but the Webb is so huge, it will be folded up and wheeled in.

Quoting Smithsonian National Air and Space Museum | Vought OS2U-3 Kingfisher:

The Kingfisher was the U.S. Navy’s main ship-primarily based, scout and observation aircraft for the duration of World War II. Revolutionary spot welding strategies gave it a smooth, non-buckling fuselage structure. Deflector plate flaps that hung from the wing’s trailing edge and spoiler-augmented ailerons functioned like additional flaps to permit slower landing speeds. Most OS2Us operated in the Pacific, where they rescued numerous downed airmen, like World War I ace Eddie Rickenbacker and the crew of his B-17 Flying Fortress.

In March 1942, this airplane was assigned to the battleship USS Indiana. It later underwent a six-month overhaul in California, returned to Pearl Harbor, and rejoined the Indiana in March 1944. Lt. j.g. Rollin M. Batten Jr. was awarded the Navy Cross for generating a daring rescue in this airplane below heavy enemy fire on July four, 1944.

Quoting Smithsonian National Air and Space Museum | Boeing B-29 Superfortress &quotEnola Gay&quot:

Boeing’s B-29 Superfortress was the most sophisticated propeller-driven bomber of Planet War II and the first bomber to property its crew in pressurized compartments. Though created to fight in the European theater, the B-29 discovered its niche on the other side of the globe. In the Pacific, B-29s delivered a variety of aerial weapons: traditional bombs, incendiary bombs, mines, and two nuclear weapons.

On August 6, 1945, this Martin-constructed B-29-45-MO dropped the very first atomic weapon used in combat on Hiroshima, Japan. Three days later, Bockscar (on display at the U.S. Air Force Museum close to Dayton, Ohio) dropped a second atomic bomb on Nagasaki, Japan. Enola Gay flew as the advance weather reconnaissance aircraft that day. A third B-29, The Wonderful Artiste, flew as an observation aircraft on both missions.
