Wow, this looks like it’s harder to make than than the street legal kart.
Junior Cadet Space Helmet
As any budding young astronaut will tell you, his most important piece of equipment is a realistic helmet with light, radio, oxygen tanks, and plenty of colorful armor.
WETHER they’re solving re-entry problems on the living room banister or stalking Martians in the orchard, junior spacemen need plenty of imagination-inspiring equipment. So vital a piece as the helmet should be built at home where the astronaut can help and be sure the construction meets space-age requirements.

I love this. The 3 page description of how man will explore the moon includes this crucial fact: “Movies may be shown, if desired.”
HOW WE WILL EXPLORE THE MOON
An original MI design by FRANK TINSLEY
EARTHMEN who land on the moon will need a special lunar vehicle for exploration. The vehicle must be self-sustaining and capable of traversing both the smooth, dust-paved crater beds and climbing the steep rocky passes of their mountainous rims.
Mi’s design for this difficult job is a giant Moon Explorer unicycle with a spherical body mounted inside its rolling rim and composed almost entirely of inflated fabric parts. These constitute the lightest possible structure and can be easily disassembled and deflated for storage.
The Moon Explorer is 32 ft. high. It is driven by electric motors and stabilized and steered by gyroscopic tilting. Power is derived from a circular “parasol” faced with solar batteries that always face the sun. Those atop the disc are of the light-actuated type. The bottom units are thermal generators, extracting electricity from reflected ground heat. This arrangement uses every inch of area and constitutes a simple, long-lived generator with no moving parts. It not only produces free power but also serves to shield the vehicle’s body from the burning rays of the unfiltered lunar sun. Despite its large size, the parasol is extremely light in weight. It consists of an envelope of thin, inflated fabric, stiffened by internal spokes and a rim of inflated tubing. It is carried above the wheel tread on four light magnesium legs and mounted on a ball-joint so it can be tilted to any angle. An electric eye, linked to gyros in the hub, controls its movements automatically.

I’m not sure if they still do this at the new Hayden, or if they do elsewhere, but it’s really cool. Basically using a set of mirrors they project an image of the sun onto the roof of the planetarium, so you get 26 foot wide image that’s safe to stare at.
Bringing the Sun Indoors
AT the Hayden Planetarium in New York a huge 26-foot image of the sun is being projected on the interior of the dome every day that the sun shines. This is accomplished by means of a first system of moving and fixed flat mirrors for bringing the sun’s image indoors and a second system of mirrors and lenses for enlarging and projecting it.
The actual sun is shown at the top of the drawing. Its rays are caught by an eight-inch flat mirror mounted on an axis parallel with the earth’s axis. A clock-like mechanism slowly turns this mirror as the earth’s turning “moves” the sun. This image, after passing through an opening in the building, is kept constantly spotted on a second flat mirror which is permanently fixed in position. It in turn passes the image downward to the third element of the Jong optical train, a flat mirror fixed at a 45-degree angle which turns it horizontally. The sun’s image is now where it can be used but as yet it is neither magnified nor projected.
Magnification is done in an ordinary eight-inch reflecting telescope, just as it would be if that telescope were directed at the sun out of doors; and since it is possible with any telescope to view the image not alone by looking into the eyepiece but also by projecting it on a screen at some distance from the eyepiece, the same is done at the planetarium. Here the distance is long, hence the image is very large—larger, in fact, than any solar image previously projected by similar methods. All this apparatus—the coelostat, fixed flats, and telescope—is entirely separate from the regular planetarium apparatus and could be similarly used with any ordinary house or building.
This reminds me of the ill-fated Rotary Rocket company.
Daring Rocketmen to Invade the Stratosphere
The rocket-shooters are going to pitch in again this coming summer. Undaunted by reverses and tragedies during the past year’s experiments, the rocketeers are tackling their work with renewed vigor and ambition, plus improved apparatus and chemicals.
Ernst Loebell, famous German engineer and rocket designer, promises to bring the rocket engines to their greatest point of achievement next summer. He is now in this country and is an active worker in the Cleveland Rocket Society.
Loebell has been carrying on bis preliminary experiments on the big Hanna estate in a suburb of Cleveland. In their operations the Cleveland group has been making use of the lessons taught by the experiments of Loebell’s countryman, the late Reinhold Tilling, a noted radio engineer and rocket builder.
Prior to his death. Tilling had been experimenting with rockets and rocket planes for months. The success of a rocket which reached a height of (6,000 feet in 1931 spurred him on to the construction of a rocket with glider wings which unfolded when the fuel was exhausted and brought the projectile gently to earth. This feat was hailed as one of the first practical steps toward the development of mail and passenger carrying rockets.
The Tilling rockets were set in motion by telignition from a distance of 100 yards. They attained a speed of 700 miles an hour and landed five miles from the starting point, in accordance with calculations. Herr Tilling was working on a system designed to manipulate his rockets by radio control when he and a female assistant were killed in the explosion of a rocket which they were charging.
