Comments Off on A Space Anniversary for the Cold Warriors

Forty-five years ago today — September 24, 1964 — a Minuteman II intercontinental ballistic missile launched for the first time on a test flight from Cape Canaveral.

Hats off to all my missileer friends whose alert posture kept us safe during the Cold War and beyond — and deter nuclear aggression today. It was an honor to serve with you, even if my part was just to put together emergency action messages.

If you’re planning to visit South Dakota, you might consider adding the Minuteman Missile National Historical Site to your travel itinerary.

And 10 years ago today, in 1999, an Athena rocket launched the Ikonos-2 remote sensing satellite from Vandenberg AFB. Ikonos-2 was a non-military reconnaissance satellite, and the first of a “new generation” of high-resolution (1 meter) commercial imagers.

A Difficult Space Anniversary: Mars Mission Failure

Ten years ago today — September 23, 1999 — the Mars Climate Orbiter spacecraft fired its main engine to go into orbit around Mars. The maneuver was unsuccessful, however, due to a navigation error. The spacecraft was lost.

The “navigation error” — i.e., the root cause of the failure — was contention between English units and metric units in the ground-based navigation software. It was a glitch in the program, and could be considered a systems engineering failure or a configuration management failure in that the error crept in because two different teams — the Colorado-based spacecraft team and the California-based mission navigation team — used two different measurement systems.

The spacecraft had been launched on a Delta-II rocket from Cape Canaveral Air Force Station on December 11, 1998.

While I’m at it, and for no better reason than that I’m pleased with the work I did on it, here’s a link to the newly-updated North Carolina Aerospace Initiative web site.

Apollo Test Launch, 45 Years Ago, and Lunar Mapping Today

Comments Off on Apollo Test Launch, 45 Years Ago, and Lunar Mapping Today

Forty-five years ago today — September 18, 1964 — NASA launched a Saturn-1 booster from Cape Canaveral in mission SA-7, also known as Apollo “Boiler Plate 15.” The launch demonstrated the Launch Escape System (LES) for the first time.

Anything Apollo-related of course reminds me of the moon, but I’ll skip the shameless plug in favor of some exciting news about the current LRO mission:

After two months of checkout and calibration, NASA’s $504 million Lunar Reconnaissance Orbiter was maneuvered into a circular 31-mile-high mapping orbit Tuesday and scientists said Thursday the spacecraft’s instruments are delivering intriguing clues about the possible presence of water ice.

The exciting news and “intriguing clues” are indications that hydrogen deposits may exist not only in permanently-shadowed craters near the south pole, but elsewhere on the moon as well — perhaps buried under lunar soil. Whether they’re water, or ammonia, or methane, or something else is unclear, but there appears to be something there, and probably something useful. Read the whole Spaceflight Now report here.

Of X-Planes and Moon Rocks

Comments Off on Of X-Planes and Moon Rocks

Fifty years ago today — September 17, 1959 — Scott Crossfield made the first powered flight in an X-15, dropped off the wing of NASA’s B-52 flying out of Edwards AFB, CA.


(Cutaway drawing of the X-15. NASA Photo E62-7893.)

Here’s a NASA story commemorating the first flight, and a nice feature on Crossfield and his career.

And forty years ago today, the Smithsonian Institution unveiled the first lunar rock ever put on public display: brought back by Apollo-11, of course. Today I wonder if we have the national will to go back to the moon, or to go anywhere; the recent Augustine Panel noted that it’s technically feasible, but by damn it better be technically feasible by the 2020s if we did it back in the 1960s. It’s all a matter of money, and whether we see it as a cost or as an investment.

For the moment we have to content ourselves with the Lunar Crater Observation and Sensing Satellite (LCROSS) mission, due to smash into crater Cabeus-A in about three weeks to try to verify if the hydrogen concentrations detected on the moon are in the form of water ice.

I hope LCROSS finds water, and more than expected . . . but even if it doesn’t, that’s only one spot in one crater. It will take other investigations to prove whether the moon is completely devoid of water. (Why I care: The characters in my novel collect ice that’s been dredged up microgram by microgram out of the bottom of Faustini crater, and since Faustini was on the “short list” of possible LCROSS impact points [according to a graphic shown during the 11 September press conference] I think my fictional world is still plausible for now.)

Comments Off on National Aerospace Day

Happy Aerospace Day to one and all!

That’s right: September 16, 2009 was designated National Aerospace Day by resolutions passed in the House and the Senate. (See this Reuters article.) Key passages of the resolution say,

  • “… the United States aerospace industry is a powerful, reliable source of employment, innovation, and export income, directly employing 831,000 people and supporting more than 2,000,000 jobs in related fields”
  • “… aerospace education is an important component of science, technology, engineering, and mathematics education and helps to develop the science and technology workforce in the United States”
  • “… aerospace innovation has led to the development of the Global Positioning System, which has strengthened national security and increased economic productivity”
  • “… the aerospace industry assists and protects members of the Armed Forces with military communications, unmanned aerial systems, situational awareness, and satellite-guided ordinances”

and the resolution “recognizes the contributions of the aerospace industry to the history, economy, security, and educational system of the United States.”

I’m happy to bring you this announcement, and to be part of the growing aerospace industry in the state of North Carolina as the Associate Director of the North Carolina Aerospace Initiative. If you know anyone working in aerospace in North Carolina, or a young person interested in an aerospace career, send them my way and let them know we’re here to help!

Comments Off on 50 Years Ago: World's First Lunar Probe

Fifty years ago today — September 12, 1959 — the Soviet Union launched the Luna-2 mission on a Vostok rocket from the Baikonur Cosmodrome. As noted, Luna-2 was the first probe to hit the moon: it impacted east of the Sea of Serenity (Mare Serenitatis).

One interesting element: Luna-2 carried a flag with the USSR’s hammer-and-sickle and a “September 1959” banner, making it the first mission to plant a flag on the moon.

Comments Off on Space History: Big Joe 1 and STS-64

Fifty years ago today — September 9, 1959 — the Mercury capsule test “Big Joe 1” launched from Cape Canaveral on an Atlas rocket. The booster operated nominally but its two outboard engines didn’t separate as planned, which left the payload 500 miles short of the predicted impact point; the overall test flight was still considered a success.

And fifteen years ago today, in 1994, Richard N. Richards, L. Blaine Hammond, Jr., Jerry M. Linenger, Susan J. Helms, Carl J. Meade, and Mark C. Lee launched from the Kennedy Space Center aboard Space Shuttle Discovery on mission STS-64.


(STS-64 mission patch, from NASA.)

The STS-64 mission was the first flight of the LIDAR (i.e., light detection and ranging, like radar but with lasers instead of radio) In-Space Technology Experiment, or “LITE.” Astronauts Lee and Meade accomplished the first untethered U.S. space walk in 10 years.

Comments Off on Genesis Crash

Five years ago today — September 8, 2004 — NASA’s Genesis sample return capsule crash-landed in the Utah desert. The spacecraft was returning with samples collected from the solar wind, but its drogue parachute failed as it descended. It hit the ground traveling 311 km/hr.

(Genesis sample container crash site. Click to enlarge. USAF photo from NASA web page.)

The damaged container was taken into a clean room as soon as possible so NASA scientists could analyze the sample fragments. This page explains how some of the Genesis findings solved a mystery about the isotopic composition of lunar rocks brought back by the Apollo missions.
