When Religions Grow Up

Comments Off on When Religions Grow Up

If part of growing up is realizing that you can’t realistically expect to get everything you want, what happens to religions when they grow up?

Is it a mark of maturity for a religion that it accepts that not everyone will (or will want to) adhere to it?

I think about Jesus and the rich man — sometimes described as a “rich young ruler” — who asked him what he needed to do to gain eternal life (Matthew 19:16-22). The man walked away from the opportunity, and what did Jesus do? Did Jesus chase the man down, berate him for his stubbornness, or threaten to take his life if he didn’t repent and convert? Not at all. Jesus let him go, and used the event as a teachable moment for his disciples.

When Christianity was in its infancy, still an underground movement, it brought in Jews and Gentiles by way of powerful testimonies and the awesome revelation that God had made a way for people to be saved and changed. Coercion never seemed to come into play, for two reasons. One, because the faith (and the nascent Church) was relatively powerless to coerce anyone to join. Second, and to my thinking more interesting, is because the faith was based on traditional Jewish belief and Judaism, being already a venerable religion, was a mature faith and one that valued being set apart, a small island of monotheistic faith in the ocean of pagan humanity.

As the capital-C Church grew into what I consider its adolescent years, and especially as it obtained official status in the Roman Empire under Constantine, it became much more belligerent. Coercion became more acceptable to church leaders, both as a means to convince people to join and as a means to enforce adherence to doctrine. (We may remember that Judaism’s early days — its adolescence, if you will — also had its coercive phase, when the Jews established themselves as a nation through military victory.)

This leads to the question of Islam, which appears to be a religion still in its adolescence. It went through an adolescent phase before, spreading through coercion and conquest and gaining worldly power that it wanted to protect and expand. Faced with mounting opposition, it retreated into relative isolation; in its recent rise to prominence (or notoriety), however, it seems again to be going through adolescent tantrums, only this time with suicide bombers and AK-47s instead of dervishes and scimitars. The question in my mind is whether Islam as a religion will grow up, will grow out of this petulant and demanding phase, and how long it may take. It seems that it will take the Muslim equivalent of Martin Luther, someone who can initiate an Islamic Reformation, in order for Islam as a religion to mature beyond the need to spread itself by intimidation. That would be a wonder to behold; remember what Luther went through, and think what a Muslim reformer would face.

It also raises the question, to me, of whether the Christian Church is growing old gracefully. It’s one thing for us as Christians to eschew violence (Jesus, you may recall from Matthew 5:38-42, didn’t go in for “eye for an eye”) and to accept that some people will hear the Gospel and remain unmoved. But it would be a shame if we became so “mature,” so insular, so content in the old-folks’-homes of our churches, that we stopped caring about and for the world around us. May it never be.

Comments Off on Budgeting Radiation on Space Shuttle CHALLENGER

Twenty-five years ago today — October 5, 1984 — space shuttle mission STS-41G launched from the Kennedy Space Center.

Space Shuttle Challenger carried U.S. astronauts Robert L. Crippen, Jon A. McBride, Kathryn D. Sullivan, Sally K. Ride, David C. Leestma, and Paul D. Scully-Power, and Canadian astronaut Marc Garneau. This was the first space flight to include two women, and Kathryn Sullivan became the first female U.S. astronaut to perform a spacewalk. Garneau was the first Canadian payload specialist to fly in space, and Scully-Power was the first oceanographer in space.

The crew deployed the Earth Radiation Budget Satellite early in the flight; the ERBS was part of a larger Earth Radiation Budget Experiment (ERBE) comparing the energy absorbed by the earth with what the planet emits into space.

The crew spent the rest of their eight days in orbit performing various experiments. In one, they demonstrated the possibility of refueling satellites in orbit.

Comments Off on First Images of the Far Side

Fifty years ago today — October 4, 1959 — the first probe to return pictures of the far side (not the “dark side”) of the moon was launched. The Luna-3 flyby mission launched on a Vostok rocket from what is now the Baikonur Cosmodrome.


(Luna-3’s first image of the far side of the moon. From the National Space Science Data Center.)

On the same day, the U.S. launched “Little Joe 6,” from Wallops Island, Virginia, to test the Mercury space capsule’s integrity and aerodynamics. The capsule reached 37 miles altitude and flew 79 miles downrange, and the mission was listed as “partially successful.”

The space race was on, a half century ago. Thinking about it makes me wonder if we have the national will to start running a space race again, with the Chinese and the Indians in the mix.

In the Old Days, Everyone Was a Rocket Scientist

Comments Off on In the Old Days, Everyone Was a Rocket Scientist

Our first space history item is interesting, but not the main event: On October 1, 1949 — 60 years ago today — the Long Range Proving Ground was activated at Cape Canaveral, Florida. It became the Florida Missile Test Range, and eventually Patrick Air Force Base and the Kennedy Space Center.

But the event that elicited this post’s subject line happened 40 years ago today, in 1969, when the European satellite “ESRO-1B” was launched from Vandenberg AFB by a Scout rocket. The NASA press release for the launch is very interesting: it includes pages of background information that must have fed the interest and imagination of every would-be “steely-eyed missile man” in the general public.

I had to grab the press release from the Google cache because the NASA link was broken, and I’ll only copy a few paragraphs here:

September 28, 1969
RELEASE NO: 69-138
FOURTH ESRO SATELLITE TO BE LAUNCHED

A 176-pound satellite carrying eight experiments to study the polar ionosphere, the Northern Lights and related phenomena, is scheduled to be launched by a four-stage Scout rocket from the Western Test Range, Calif., no earlier than Oct. 1, 1969. Called ESRO-1B, the European designed and built satellite is the fourth in a cooperative program between the European Space Research Organization (ESRO) and the National Aeronautics and Space Administration (NASA). The program is carried out under terms of an agreement signed by the two organizations in December 1966, relating to providing ESRO with launching and associated services.

ESRO-1B is a duplicate or backup version of ESRO 1-Aurorae, a cooperative ESRO/NASA project, which was successfully launched into a highly elliptical near polar orbit by NASA on October 3, 1968, and is still operating. The same complement of eight experiments–a series of high-latitude particle detectors, auroral photometers, and Langrnuir probes–is being carried on board ESRO-1B. The experiments were provided by the Technical University of Denmark; Kiruna Geophysical Observatory, Sweden; the Radio and Space Research Station, Slough, England; the University of Oslo, Norway; the University of Bergen, Norway; the Norwegian Defense Research Establishment; and the University College, London, England.

The orbit planned for ESRO-1B is near-polar, inclined 86 degrees to the Equator, with an apogee of 435 kilometers (about 270 statute miles) and a perigee of 400 kilometers (about 248 statute miles). Orbit period will be 92 minutes. Scientific measurements made by the ESRO-1B will be concentrated over Northern Europe to enable correlation between ground-based polar ionosphere observations and measurements made simultaneously with sounding rockets launched from the ESRO launch site at Kiruna, Sweden.

Once injected into orbit, the ESRO-1B will be despun by means of a yo-yo system to about 1 RPM. Final stabilization will occur about 10 days after launch when the spacecraft locks onto the Earth’s magnetic field. This stabilization is achieved by means of a pair of magnets inside the satellite. To minimize oscillations, slender magnetic rods are also mounted inside the satellite.

And so on. On page 10 of the news release:

ESRO-IB FACT SHEET

Launch Window: 30-minute window which changes only slightly from day to day. The window opens at 3:29 p.m., (PDT), October 1, 1969.
Launch Site: Western Test Range, Lompoc, California, Pad SLC-5.
Launch Vehicle: Four-stage solid fuel Scout rocket.

Orbit:
Apogee: 435 km (about 270 statute miles)
Perigee: 400 km (about 248 statute miles)
Period: 92 minutes
Inclination: 86 degrees
Stabilization: Spacecraft is spin stabilized at about 148 rpm initially. Despun to one rpm by yo-yo mechanism and further despun by magnetic system which interacts with Earth’s magnetic field. Stabilization thereafter will be provided by a passive system consisting of two permanent magnets.

I find the inclusion of all the detail fascinating. But maybe that’s understandable, since I still am a would-be rocket scientist.

Space Radar Mission, 1994

Comments Off on Space Radar Mission, 1994

Fifteen years ago today — September 30, 1994 — astronauts Michael A. Baker, Terrence W. Wilcutt, Thomas D. Jones, Steven L. Smith, Daniel W. Bursch, and Peter J. K. Wisoff launched from the Kennedy Space Center aboard Space Shuttle Endeavour on mission STS-68.


(STS-68 mission patch. NASA image.)

The mission carried the Space Radar Laboratory on its second flight, and imaged some of the same areas the SRL had imaged before.

Flying SRL during different seasons allowed comparison of changes between first and second flights. SRL-2 was activated on flight day one, and around-the-clock observations conducted by astronauts split into two teams. Besides repeating data takes over same locations as on first flight, unusual events also imaged, including erupting volcano in Russia and islands of Japan after earthquake there. Also tested was ability of SRL-2 imaging radars, Spaceborne Imaging Radar-C (SIR-C) and X-band Synthetic Aperture Radar (X-SAR), to discern difference between such human-induced phenomena as an oil spill in the ocean and naturally occurring film.

[BREAK, BREAK … BONUS SPACE HISTORY ITEM]

Normally I’d wait until next year to include this item, since I usually deal only in 5-year-multiple anniversaries, but this one is work-related.

I’ve been putting together aerospace history pages that focus on North Carolinians or people with connections to the state. It just so happens that four years ago today — September 30, 2005 — North Carolina astronaut William “Bill” McArthur launched on a Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan, en route to taking command of International Space Station Expedition 12.

If you know any North Carolina teachers, direct them to the NC Aerospace Initiative’s Aerospace Education section, where we will link information on NC aerospace history that they can use in their classes.

Water on the Moon, Slush on the Desk

Comments Off on Water on the Moon, Slush on the Desk

I was very excited to see the news about the latest results from lunar survey missions about the presence of water on the moon.

(Moon Mineralogy Mapper composite image. Click to enlarge. Left: Sunlight reflected off the near side of the moon. Right: Infrared image showing water and hydroxl molecule signatures near the poles. “The blue arrow indicates Goldschmidt crater, a large feldspar-rich region with a higher water and hydroxyl signature.” NASA image.)

The full story is here, but here are the highlights:

The observations were made by NASA’s Moon Mineralogy Mapper, or M3 (“M-cubed”), aboard the Indian Space Research Organization’s Chandrayaan-1 spacecraft. NASA’s Cassini spacecraft and NASA’s Epoxi spacecraft have confirmed the find….

“When we say ‘water on the Moon,’ we are not talking about lakes, oceans or even puddles,” explained Carle Pieters, M3’s principal investigator from Brown University, Providence, R.I. “Water on the Moon means molecules of water and hydroxyl that interact with molecules of rock and dust specifically in the top millimeters of the Moon’s surface.

I have a personal reason for being excited about this finding, and since so few people look at this blog I assume all of you already know what that reason is. So let’s move on to the slush on my desk.

Literary slush — unsolicited manuscripts, proposals, and queries — moves on and off my desk in waves. Reading it can be mind-numbing, but it can also be interesting and sometimes even entertaining. It’s not often a source of inspiration, but my writing friend Jim Hines wrote an ode to the slush pile entitled “Slush Reading, Seuss Style” that is absolutely fantastic. Check it out!

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

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.
