July 23 marked the 20th anniversary of the launch of the shuttle Columbia on mission STS-93, commanded by Eileen Collins, the first female commander of a shuttle mission. (The launch had been scheduled for July 20th, the anniversary of the Apollo 11 landing, but scrubbed by a technical issue.) For astronomers, though, the mission is historic because is placed into orbit the Chandra X-Ray Observatory, a giant x-ray telescope that was one of NASA’s original “Great Observatories” alongside Hubble and others.

The X-33, which failed to take flight even once after spending more than $1 billion on it, is one of the most infamous examples of failed spaceplane projects. (credit: NASA)In recent issues of The Space Review, Mike Snead has surveyed the history of, and options for, commercial passenger spaceflight (see “Solving the commercial passenger spaceflight puzzle”, Part 1, Part 2, Part 3; September 3, 9, and 16, 2019). This valuable document is nearly 16,000 words long, with excellent illustrations, and is probably the most useful record of the fraught history of this topic for many years. He makes this key point: despite what some would have us believe, outer space will not be permanently opened to commercial development and settlement without first establishing acceptably safe commercial passenger spaceflight.

NASA astronauts Christina Koch and Jessica Meir work outside the ISS during their historic all-woman spacewalk last Friday. (credit: NASA)It was a milestone that came both earlier than expected but later than desired.
When NASA announced early this month its plans to conduct a series of spacewalks to replace batteries in the station’s power supply, it announced astronaut pairings for the five spacewalks it expected it would take to replace the batteries. That included a spacewalk on October 21 by Christina Koch and Jessica Meir, which would have been the first spacewalk by two female astronauts—a milestone previously planned for the spring, but cancelled because of a spacesuit sizing issue that generated its share of negative reactions.

Constellations like SpaceX’s Starlink could provide broadband Internet access globally, but also jeopardize astronomy and threaten safe operations in low Earth orbit, effects that need to be considered by a wider audience. (credit: SpaceX)The drafters of the Outer Space Treaty could not have predicted artificial constellations that hinder astronomical observing and storm tracking, actors shooting down space debris, and tardigrades unknowingly placed on a lunar lander and subsequently spilled on the Moon. This is, of course, to say nothing of human survivability in non-Earth environments. A critical component of assessing our impact on other worlds is assessing other worlds’ impact on us, both physically and socioeconomically. Physically, neither space agencies nor private spaceflight companies have conducted sufficient research regarding human survivability in space, in terms of radiation exposures, differences in gravity, psychological complications, and many other factors.

The Manned Orbiting Laboratory was from the beginning an operational reconnaissance platform rather than a “laboratory” for military space experiments. The US Navy learned this the hard way.One of the enduring mysteries of the National Reconnaissance Office’s Manned Orbiting Laboratory (MOL), an ambitious space station program that started in late 1963 and was rather abruptly canceled in summer 1969, is to what degree it was ever a “laboratory.” There is information indicating that about a dozen different experiments were considered for the space station. And yet, the remaining astronauts who worked on the project, and substantial documentation, indicate that the laboratory name was primarily a public cover story for the project’s real mission: taking high resolution reconnaissance photographs of the Soviet Union. The experiments were all, or mostly, eliminated.
