He who keeps cool will collect (photons): Christian Ready on the JWST instrument package

Sports Illustrated quoted this Japanese proverb back in 1975 in conjunction with Cal’s championship men’s gymnastic team of that era.  The adage abides with the James Webb Space Telescope now in its halo orbit around the Sun-Earth L2 point, its optics and instruments slowly cooling to their ultimate cryogenic temperatures, the better to collect the faint signs of heat from the early universe.  Little has been said to the public about the instruments nestled in the big box behind the 6.5-m primary mirror.  This is perhaps not surprising.  There are no secrets here, just that the real science goals and the optical engineering to meet them are fiendishly complex.  Friendly Neighborhood Astronomer Christian Ready tackles the challenge, explaining where the precious photons will go and what will happen to them once they arrive.  The comment section clamors for more detail on the MIRI cryocooler which will take the mid-Infrared Instrument’s focal plane array below 7K.  Here’s to hoping for a full video on this beast, built across the hall from me, and on which I spent a couple of weeks when the team was shorthanded.

Bird Up: JWST completes major deployments

As the man said after the Eagle landed: “You got a bunch of guys about to turn blue. We’re breathing again. Thanks a lot.”

The James Webb Space Telescope, largely designed, built, and tested at Space Park in Redondo Beach, has launched, raised itself from the spacecraft, deployed its 5 layer sunshield, and put its primary and secondary mirrors into place.  It will take another few months for the telescope to cool in the shade and then to commission the instruments before science measurements can begin.

It has been a long and contentious wait but the magnitude of this accomplishment is worth celebrating.

Redondo Redux: Romance of the Ranchos on the Beach Cities

In days of old, when the city was pronounced ‘Los Anguluz’ and radio ruled the waves, “Romance of the Ranchos” offered  half-hour looks at the many regions that congealed into our present megalopolis.  Herewith the episode on what are now the Beach Cities.

Dicta Prius: Redondo Beach’s Hybrid History

Page 1 of TRW’s Hybrid Engine patent, submitted on 17 March 1969 and issued 2 March 1971 (Click to enlarge)

It has been fifty years since a group of engineers submitted what would become United States Patent 3566717. Entitled “Power train using multiple power sources,” Baruch Berman, George Gelb, Neil Richardson, and Tsih Wang of then-TRW in still Redondo Beach described the hybrid gas/electric vehicle. As a satisfied Prius owner since 2012 and likely repeat customer, I only recently learned that the core engine technology was invented a mile from my house and possibly yards from my office.

In those seven years of hybrid ownership, I’ve often wondered what actually goes on under the hood.  Niels Blaauw offers a charming overview of older implementations of the engine and drivetrain.  Next, Professor John Kelly of Weber State University dives deeply into the innards of the transaxle that’s in my generation of Prius.   His WeberAuto channel is a gearhead’s goldmine.
