Project Hyperion (interstellar). Project Hyperion, launched in December 2011 by Andreas M. Hein in the context of Icarus Interstellar, is a project aimed at performing a preliminary study that defined integrated concepts for a crewed interstellar starship or generation ship. This is a study mainly based out of the WARR student group at the Technical University of Munich (TUM). The study aims to provide an assessment of the feasibility of crewed interstellar flight using current and near-future technologies. It also aims to guide future research and technology development plans as well as to inform the public about crewed interstellar travel.

Notable results of the project include an assessment of world ship system architectures and adequate population size. The project has also been featured in the TV-series Rendezvous with the Future (BBC/Bilibili), popular science books as well as art.

The core team members have transferred to the Initiative for Interstellar Studies's world ship project and have presented their results at the ESA Interstellar Workshop in 2019 as well as in ESA's Acta Futura journal.

An interdisciplinary design competition was launched in 2024.

Phenoxyacetic acid. Phenoxyacetic acid, POA, is a white solid with the formula of C8H8O3. Although not itself usefully active as an herbicide, it forms the part-structure of many phenoxy herbicide derivatives including MCPA and 2,4-D.

Structure and synthesis 
Phenoxyacetic acid is an O-phenyl derivative of glycolic acid. It is both a monocarboxylic acid and an aryl ether. Its preparation from sodium phenolate and sodium chloroacetate in hot water was first reported in 1880.

1) C6H5O−Na+  +  ClCH2COO−Na+  →  C6H5OCH2COO−Na+ + NaCl

2) C6H5OCH2COO−Na+ + HCl →  C6H5OCH2COOH + NaCl

The phenolate anion reacts via nucleophilic attack on the methylene carbon of the chloroacetic acid, forming an ether bond.

Properties 
Phenoxyacetic acid is a white or clear crystalline compound at room temperature. When impure, it can appear to be a light tan to brown. The compound has a solubility in water of 12 g/L and is highly soluble in organic solvents including ethanol, diethyl ether and benzene. Phenoxyacetic acid is a weak acid and weak base with a pKa of  3.7.

Uses 
Phenoxyacetic acid has found minor uses as a food additive and perfume component and is categorised as "generally recognised as safe" in these applications.

Kawanishi K-3. The Kawanishi K-3 was a Japanese, fast, multi-purpose civil transport aircraft from the early 1920s. Despite its good performance it was eclipsed by the release of Army surplus machines and only one was built.

Design and development

The K-3, completed in October 1921, was designed as a fast civil transport able to carry two passengers or mail and other cargo. It was a development of the Kawanishi K-1 completed in December 1920 and was more powerful, aerodynamically cleaner and faster. Like most aircraft of its period it had a wooden structure and was fabric-covered.

It was a single bay biplane with rectangular plan wings braced by parallel pairs of interplane struts. The upper wing was joined to the upper fuselage by a cabane formed by pairs of transverse outward-leaning inverted V-struts to the forward wing spar and similar but longitudinal V's to the rear. The lower wing was joined as usual to the lower fuselage longerons.

At the end of World War I Japan received a large number of Maybach engines, designed to power airships, as part of its war reparations. The K-3 was the first Japanese aircraft to use one, a Maybach Mb.IVa six cylinder, water-cooled, upright straight engine producing . Its radiator was mounted horizontally in the upper wing centre section to reduce drag. It was nose-mounted and smoothly faired into the fuselage behind. An open, underwing cockpit seated two passengers side-by-side, with the pilot in a second open cockpit well behind the wing trailing edges.

The K-3 had a fixed, conventional undercarriage with mainwheels on a single axle with pairs of faired landing legs and rearward drag struts mounted on the lower fuselage longerons. There was a short tailskid.

Operational history

The K-3 first flew in the early winter of 1921. It was the fastest civil aircraft in Japan, with the speed of a fighter and the load-carrying ability of a light bomber. Kawanishi had hopes of commercial success but instead the light civil transport market was filled by the lower-powered and slower Nakajima Type 5 Trainers released by the Army and no more K-3s were built.

In 1926 the sole K-3 was modified to take a straight six,  Benz Bz.IIIaV (Benz Bz.IV) engine as well as other changes to become the Kawanishi K-3B.
