Disasters in Space: Tragic Stories From the US–Soviet Space Race
Disasters in Space: Tragic Stories From the US–Soviet Space Race, Hermann Woydt, 2018, ISBN 978-0-7643-5617-9144 pp.
Author Hermann Woydt has given historians a empty niche filling work. He addresses, throughly yet concisely, the human cost of space exploration to date—a question left unanswered until this welcome arrival of Disasters In Space. Most readers will recall a lethally catastrophic event here or there but Woydt’s work gives readers a view from on high as well as close up yielding a deep understanding of space exploration’s human dimension.
Disaster brings forth deep emotion which is often expressed through art and Hermann Woydt is sensitive to this with his understated, though powerful, opening images of NASA’s black granite Space Mirror Memorial and of the soaring Monument to the Conquerers of Space located in Moscow.
Woydt’s description of these historic, and headlining events, is clear and easy to read. His research into the detail of each disaster is refreshing and thorough. This is no cursory or vicarious book. This book is a work worthy of any library concerned with the specialties of aerospace’s history or exploration’s history in general. Decisions made which ended in unintentional death are explained in the context of the time as well as their resultant corrective measures. There is much to learn and see within this handily sized book. We learn, for example how the unintended simultaneous detonations of only two explosive bolts, not in sequence as intended, caused the deaths of three cosmonauts. Deep knowledge comes from Woydt’s understanding why the decision was made to have three cosmonaut’s in the Soyuz capsule which began the chain of purposeful decisions leading to the loss of three fine souls. Woydt equally tends to the Challenger as well as Columbia disasters with this same deep understanding. The chapter on Spaceplane SpaceShip 2 is incredibly timely as space exploration become increasingly privatized. We learn that, though the crash is chiefly attributed to pilot error, there were design decisions which directly fomented the co-pilot’s crash inducing error.
There is much in between as the near disasters in the Gemini and Apollo programs attest.
Woydt may have a wry sense of humor as there are 13 events, each having its own chapter, in Disasters in Space. Or is it coincidence? Regardless, it shows the author’s talent. This book is as important for the historical descriptions as it is for the painful lessons learned as humankind found its way into space.
Hornet at Mach
The magic of a fast mover just at Mach 1 with the rapid and continuing condensation of water vapor behind the compression of the shock wave where the pressure rapidly drops. At times there are multiples—just aft of the cockpit canopy for example.

SOFIA On the Fly
NASA operates a Boeing B-747SP (see previous posts) so that a unique IR telescope can be carried aloft. This is SOFIA (Stratospheric Observatory for Infrared Astronomy)—a telescope which senses within the infrared portion of the light spectrum. This telescope is quite large and more capable than those based on land or in orbit. SOFIA is a cooperative mission between the USA’s NASA and Germany’s Deutsches Zentrum für Luft- und Raumfahrt (DLR, or the German Aerospace Center). DLR built the quite large IR telescope which has a diameter of 2.5m (100 inches) and weighs 20,000kg (44,100 lbs)—operating within the frequency range of 0.3–1600 μm (microns). It is a Bent Cassegrain/Nasmyth design and serves to gather information especially from nebular gas clouds which is fed to instruments aboard the NASA’s 747SP. One of these instruments is known as GREAT, an acronym for German Receiver for Astronomy at Terahertz (frequencies), though there are many other instruments, as well. Recently the frequency was nearly doubled from ~2 THz to 4.1 THz vastly increasing the richness sensed by the telescope.
Being airborne, the telescope can be positioned nearly anywhere in the world (so celestial events can be observed at the optimum coordinate and time) and it is above 99% of the Earth’s atmosphere (eliminating nearly all of its adverse effects). Aircraft vibrations are zeroed out with actuators which sense these vibrations and counteract them, effectively providing a vibration free base.
The aircraft (N747NA) was originally built for Pan American Airways in 1977 and christened Clipper Lindbergh. Later it was sold to United Airlines and retired thereafter. Later acquired by NASA it was fitted for flight and modified to carry the large telescope aloft in a fuselage bay located between the wing and the tail. A large hatch (shutter) can be rotated upward to expose the telescope to observe the heavens as well as to expose what is known as “the cavity” to the harsh conditions of the stratosphere. The aircraft is designed to fly 900 missions per year at an altitude range of 39,000–45,000 feet (~11,800–~13,600 meters) with as many as 25 persons on board for eight hours of observation at a time—all at -60º C (-76º F) and 800kph (500 mph). Clipper Lindbergh was refitted after 2011 with most of the science system wiring replaced (15,000 connections were rewired), three times more power made available to the scientific instruments, the telescope mirror cleaned, the cavity door improved as well as the cavity’s environmental control (better keeping water as well as water vapor out) and the cockpit was transformed from analog based to digitally based (i.e., a glass cockpit).
The IR telescope is the pointed end of the stick investigating the chemical reactions which have occurred (since the light received was emitted ages ago the past tense seems appropriate to use) so that galaxy evolution, planetary system formation and the chemical intricacies of stellar gas clouds can be fathomed.

The Royal Navy’s newest aircraft carrier is innovative for its two islands and is wedded to the Lockheed F-35B Lightning II S/VTOL for offensive potential. The ramp as well as the Lightning’s vertical lift system (the engine drives a downward directed fan located aft of the cockpit at the expense of fuel storage volume of the F-35A and F-35C) eliminate the requirement for catapult systems. Additionally, the aircraft (Lightnings as well as helicopters) aboard the HMS Queen Elizabeth do not require arresting cables. No tail hooks here.
Super Carrier—only in the U.S. Navy
Occasionally, as other countries field a new or revamped aircraft carrier, much of the press (though we love them) oversimplify and speculate that the U.S. Navy is losing dominance. Hardly. Other countries field aircraft carriers. The U.S. Navy fields super carriers which have 1.5x to 2x times the number of aircraft and of greater variety for enhanced mission flexibility. No other navy has shipborne aviation assets which can perform aerial refueling. No other navy can project force with an alpha strike like the U.S. Navy. The USN super carriers, nuclear powered as they are, are limited only in aviation fuel, munitions and food—which of course can be resupplied while at sea and on the move. Aircraft carriers require support with many ships for antiaircraft, antimissile and ASW duties. As the board game Harpoon teaches us, though: the only problem greater than having an aircraft carrier is not having an aircraft carrier. And the USN has eleven super carriers—quite the advantage and most difficult for adversaries to overcome.

All HALE-D—stratospheric eye in the sky
The High Altitude Long Endurance–Demonstrator (HALE-D) is a small version of the intended ultimate design for an airship with the mission of monitoring and observation. Powered by solar film and electric thrusting motors a HALE-D should take up and maintain position at an altitude of 12 miles which would give it the capability of observing 600 square miles and millions of cubic miles of airspace. HALE-Ds have the potential to cost and operate at a fraction of satellite recce.
