Roads not taken in satellite photo-reconnaissance: Part 1, the 1960sby Dwayne A. Day Monday, October 16, 2023
An Atlas-Agena launch in the 1960s carrying a KH-7 GAMBIT reconnaissance satellite. During the decade there were numerous proposals for reconnaissance satellites that were never built, including some that would have used GAMBIT hardware. (credit: USAF)Today digital cameras are everywhere and most people under 30 will have no concept of what a film camera was. But film was a powerful storage medium for more than a century, and from the late 1950s to the mid-1980s American reconnaissance satellites depended upon it. During this period, the National Reconnaissance Office (NRO), which oversaw the procurement and operation of American reconnaissance satellites, studied numerous alternative reconnaissance satellite designs to meet new requirements.

ISRO prepares for human spaceflightby Gurbir Singh Monday, October 23, 2023
Liftoff of the TV-D1 mission October 21 to demonstrate the crew escape system for the Gaganyaan spacecraft. (credit: ISRO)In 2025, India is planning its first crewed spaceflight, carrying astronauts on an Indian launch vehicle, launched from India. On October 21, ISRO conducted an uncrewed in-flight abort test. One minute into the flight, the Crew Escape System fired for just over two seconds, pulling the crew module away from the launch vehicle. The momentum took the crew module to an altitude of 17 kilometers, where the Crew Escape System itself separated from the crew module. Neither the launch vehicle nor the Crew Escape System were recovered. The crew module descended to a safe splashdown ten kilometers downrange, first using a pair of drogue parachutes and then three main parachutes. About nine minutes after launch the mission concluded having met all the mission objectives successfully.

ISRO will be analyzing the data generated during the entire mission and is expected to undertake three more such tests to validate various technologies required to ensure the crew safety.

This flight is in preparation for a NASA-SwRI suborbital research mission that is coming up for me as well, hopefully next year. That research flight will feature two experiments: one to assess the efficacy of the spacecraft for doing suborbital astronomy, and one to take physiological data on an experimenter undergoing suborbital spaceflight.

The launch industry strains launch licensingby Jeff Foust Monday, October 23, 2023
SpaceX is continuing pad tests of its second integrated Starship/Super Heavy vehicle as it awaits an updated FAA launch license. (credit: SpaceX)There is always some degree of tension between companies and regulators in almost any industry. That tension can be healthy as both companies and government agencies seek the right balance between ensuring safety and allowing progress.

Review: Deep Skyby Jeff Foust Monday, October 30, 2023

It was inevitable, perhaps, that a very big space telescope would end up on a very big screen. Once it was clear that the James Webb Space Telescope was both a technical and scientific success, putting its dramatic images on an IMAX screen was something close to a no-brainer. “It has to be on an IMAX screen because only that giant screen is making you fully immersed in these worlds,” said Nathaniel Kahn at a National Academies event in July.

Shaking up the commercial space station industryby Jeff Foust Monday, October 30, 2023
Northrop Grumman is joining forces with Voyager Space on the Starlab space station (above), dropping plans to develop its own. (credit: Voyager Space)The early years of a new industry can be a bit chaotic. A wave of new entrants rush in, far more than can be reasonably supported by demand. The companies compete vigorously for customers and investment, while also forming—and breaking up—partnerships with one another. Ultimately, only a few will survive, with the rest subsumed by the winners or disappearing entirely.

Roads not taken in satellite photo-reconnaissance: Part 2, the 1970sby Dwayne A. Day Monday, October 30, 2023
The HEXAGON program lasted from 1971 until the loss of the last vehicle in April 1986. Throughout the life of the program there were various proposals to launch and/or retrieve it using the Space Shuttle. (credit: NRO)Throughout the 1960s, American aerospace companies proposed and/or studied various reconnaissance satellites that were never put into development. These were intended to fulfill various requirements, often not very well-defined, to improve ground resolution, area coverage, or timeliness. (See part 1 here.) That continued into the 1970s. The early part of the decade included numerous proposals for satellites to produce imagery on a much quicker basis—a day or less—than existing systems.

From the hurtling ascent, to the jam-packed three minutes of otherworldly microgravity to get our real work done, to the washboard deceleration of entry, and then the steep glide to a greased landing, it was simultaneously thrilling, fulfilling, and enchanting. And, there’s no contest, it was the single best work day I have ever had!

The FCC’s authority in regulating orbital debrisby Leighton Brown and Paul Stimers Monday, November 6, 2023
The FCC fined DISH for failing to move a satellite at least 300 kilometers above the geostationary belt as outlined in the company's orbital debris mitigation plan. (credit: ESA/ID&Sense/ONiRiXEL)In a first for space debris enforcement, the Federal Communications Commission (FCC) recently announced that it had entered into a negotiated Consent Decree with DISH Operating LLC (DISH) to resolve an investigation into whether DISH had failed to properly deorbit its direct broadcast satellite service EchoStar-7 geostationary orbit satellite. During the course of that investigation, the FCC determined that DISH had violated the Communications Act, the FCC’s rules, and the terms of DISH’s license by relocating the EchoStar-7 satellite at its end of mission to a disposal orbit below the elevation specified in its orbital debris mitigation plan and required by the terms of its license.

Big rockets for big science?by Jeff Foust Monday, November 6, 2023
Scientists working on future large missions are turning to vehicles like SpaceX’s Starship to provide more capability at lower costs. (credit: SpaceX)For the last few years, a handful of scientists have asked their colleagues to consider designing missions to take advantage of a new generation of very large launch vehicles. Those vehicles offer greater mass and volume at potentially lower per-kilogram prices, opening up opportunities for things like large space telescopes or missions to the outer regions of the solar system.

Rather than brief comments thanking spouses, parents, or other friends and family, Kelly and Zach Weinersmith thanked the “space settlement community,” but with a disclaimer: “We worry that many of you will be disappointed by some of our conclusions, but where we have diverged from your views, we haven’t diverged from your vision of a glorious human future.”

A small step forward for space-based solar power technologyby Jeff Foust Monday, November 13, 2023
An image from Caltech’s SSPD-1 mission, showing arrays for transmitting (right) and receiving wireless power mounted on the Vigoride-5 bus. (credit: Caltech SSPP)Space-based solar power (SBSP) is one of those concepts endlessly debated without little obvious progress or resolution of those debates. For more than half a century, advocates have described SBSP as a solution to growing energy demands while also serving as a source of green energy in an era of growing alarm about climate change. Critics describe the severe technological challenges and costs that make large-scale SBSP unrealistic to them.

Something goes boom in the night: the explosion of a Cold War secretby Dwayne A. Day and Asif Siddiqi Monday, November 13, 2023
The famous launch pad at the Baikonur Cosmodrome that was the launch site for Sputnik and Yuri Gagarin. It was the site of a fiery on-pad explosion in 1983 that nearly killed two cosmonauts. American satellites spotted the rocket on the pad and later the damage from the explosion. It was photographed over two decades earlier by a U-2 reconnaissance plane. (credit: CIA)In the fall of 1983 American reconnaissance satellites spotted preparations for a space launch at the sprawling Soviet missile and space launch range known as the Baikonur Cosmodrome, then popularly called “Tyuratam.” The satellites photographed activity at what the CIA labeled “Launch Site A1.”
