Comments Off on HL-10 Heavy Lifting Body, First Flight

Forty-five years ago today — December 22, 1966 — the HL-10 made its first flight at the Dryden Flight Research Facility at Edwards AFB.

The HL-10

was built by the Northrop Corporation as a “heavy” lifting body. “HL” stands for horizontal landing, and “10” refers to the tenth design studied by engineers at NASA’s Langley Research Center, Hampton, Va.

NASA research pilot Bruce Peterson made the first flight, which uncovered serious control problems in the craft. Solving those and similar problems on the various lifting body designs eventually made the Space Shuttle possible.

On a personal note, I love the fact that I got to live and work where all of this took place. Many years after the fact, of course, but it still had a high coefficient of “awesomosity.”

Comments Off on Another STARSHINE, and a Descendant of BioSat

A pair of small satellites launched on this date in space history …

First, 10 years ago today — December 16, 2001 — the crew of STS-108 released STARSHINE-2 while preparing for their return to Earth. Like its predecessors — STARSHINE-1 and STARSHINE-3 — this “microsatellite” was built with the help of students from around the world: students in 26 countries helped to polish the over 800 mirrors that studded the spacecraft’s surface, making the satellite highly reflective so they could track it in its orbit. The STARSHINE acronym stands for “Student Tracked Atmospheric Research Satellite Heuristic International Networking Experiment,” and more than 25,000 students participated in the project.

Five years later, on this date in 2006, a Minotaur rocket launched from Wallops Island, Virginia, carrying the “nanosatellite” GeneSat-1. Conceptually similar to BioSatellite-1, GeneSat-1 carried samples of bacteria — specifically, E. Coli — to monitor the effects of space radiation. Unlike the BioSatellite series, which involved returning the samples to earth for study, GeneSat-1 carried special optical instruments to observe the bacteria and radioed those observations to the ground.

Sometimes a Successful Launch Isn't Enough

Comments Off on Sometimes a Successful Launch Isn't Enough

Forty-five years ago today — December 14, 1966 — a Delta rocket launched from Cape Canaveral carrying a set of biological specimens to study how microgravity affected them.


(Biosatellite-1 launch. NASA image from Wikimedia Commons.)

Biosatellite-1 made it to orbit successfully. The overall mission failed, however, because the capsule could not be de-orbited. Its retro rocket malfunctioned, leaving the spacecraft in orbit; its orbit eventually decayed in February 1967, but that was long after the experiment’s usefulness would have passed.

Nevertheless, this NASA page about the program notes that Biosatellite-1 “provided technical confidence in the program because of excellent performance in most other areas.” The next biosatellite launch was a complete success.

One might wonder why experiments like these would be carried out, since human beings had been launched into space for years. Didn’t we already know how the space environment affected biological organisms? To an extent, yes, but as I understand it sending up small-scale, short-lived species and studying the effects on them would allow scientists to extrapolate to longer-term effects on larger organisms — like people on long-duration spaceflights.

Space Power … Electrical Power, That Is

Five years ago today — December 10, 2006 — the Space Shuttle Discovery launched from Kennedy Space Center on a mission to improve the electrical power subsystem on the International Space Station.


(The International Space Station as seen from STS-116. NASA image.)

Mission STS-116‘s crew consisted of U.S. astronauts William A. Oefelein, Joan E. Higginbotham, Mark L. Polansky, Robert L. Curbeam, Nicholas J.M. Patrick, and Sunita L. Williams, plus European Space Agency astronaut Christer Fuglesang of Sweden. With the exception of Williams, the crew spent 12 days in space; she, however, stayed aboard the ISS as the Expedition 14 flight engineer. ESA astronaut Thomas Reiter of Germany, previous ISS flight engineer, returned to Earth with STS-116.

From 1998 to 2006, the ISS had essentially been operating on a temporary power system. The STS-116 crew rectified that situation and prepared the station for its additional modules by rewiring the ISS … certainly not a complete “makeover” of the station, but in many ways an “extreme” one.

Dual Launch on a Delta-II, and an Old Test Satellite

Comments Off on Dual Launch on a Delta-II, and an Old Test Satellite

Ten years ago today — December 7, 2001 — a Delta-II launch vehicle carried two satellites into orbit from Vandenberg AFB.


(Artist’s conception of the Thermosphere-Ionosphere-Mesosphere Energetics and Dynamics [TIMED] satellite. NASA image.)

Jason-1 was a joint mission between the U.S. and France: an oceanographic satellite intended to monitor the level and wave heights of the ocean surface. The Thermosphere-Ionosphere-Mesosphere Energetics and Dynamics, or TIMED, satellite was designed to study “the physical and chemical processes acting within and upon the coupled mesosphere,” i.e., that portion of the atmosphere between 60-180 km altitude. This region of the atmosphere “is difficult to study because it is too high for even the largest research balloons and still dense enough to quickly cause a satellite to decay from orbit.”

In earlier space history, on this date 45 years ago, Applications Technology Satellite 1 (ATS-1) launched from Cape Canaveral atop an Atlas Agena rocket. ATS-1 was a test platform for new spacecraft design concepts, particularly propulsion and attitude control, as well as a remote sensing satellite that collected meterological data and cloud cover images. ATS-1 also tested improved satellite communications.

Ten years ago today — December 5, 2001 — the Space Shuttle Endeavour launched from Kennedy Space Center on a mission to the International Space Station.


(Shuttle Endeavour being readied for the STS-108 mission. NASA image.)

STS-108 delivered the Raffaello Multi-Purpose Logistics Module to the ISS. Astronauts Dominic L. Gorie, Mark E. Kelly, Linda M. Godwin, and Daniel M. Tani attached the Italian cargo module to the ISS’s Unity module, and ferried the ISS Expedition 4 crew — cosmonaut Yuri Onufrienko and astronauts Carl E. Walz and Daniel W. Bursch — to their new orbital home.

When Endeavour landed, it brought the ISS Expedition 3 crew — astronaut Frank Culbertson and cosmonauts Mikhail Tyurin and Vladimir N. Dezhurov — back to Earth.

I’ve noted elsewhere on this blog that I met Captain (USN) Culbertson several years after his return from the ISS. I sat next to him during a day-long NASA Industry-Education Forum. Good guy.

Fifteen years ago today — December 4, 1996 — a Delta-II rocket launched from Cape Canaveral Air Station carrying the Mars Pathfinder lander and rover.

Mars Pathfinder landed on Mars on July 4, 1997, and deployed the Sojourner rover (named for Sojourner Truth). After it landed, the Pathfinder’s name was changed to the Carl Sagan Memorial Station.

The mission was a great success, with the rover lasting twelve times longer than its design life and the lander lasting three times as long. The last Mars Pathfinder data transmission was sent on September 27, 1997.

Lessons learned from the Mars Pathfinder mission went into building the follow-on Spirit and Odyssey rovers, as well as the much larger and more ambitious Curiosity rover which launched November 26, 2011, on the Mars Science Laboratory mission.

May Curiosity meet with even greater success than its predecessors.

First Successful Landing on Mars

Comments Off on First Successful Landing on Mars

Forty years ago today — December 2, 1971 — the Soviet Mars-3 lander made the first successful soft landing on the Red Planet.


(Mars-3 lander model at the Memorial Museum of Cosmonautics in Russia. Image from the National Space Science Data Center.)

Mars-3 had been launched on May 28th (see this space history blog entry), hot on the heels of Mars-2. When Mars-3 landed, Mars-2 had already become the first manmade object to reach the Martian surface.

Mars-3’s landing, in contrast to Mars-2’s, went smoothly. Once the petals opened and it began transmitting, however,

After 20 seconds, at 13:52:25, transmission stopped for unknown reasons and no further signals were received at Earth from the martian surface. It is not known whether the fault originated with the lander or the communications relay on the orbiter. A partial panoramic image returned showed no detail and a very low illumination of 50 lux. The cause of the failure may have been related to the extremely powerful martian dust storm taking place at the time which may have induced a coronal discharge, damaging the communications system. The dust storm would also explain the poor image lighting.

Space History: Apollo Enters the 'Hardware Phase'

Comments Off on Space History: Apollo Enters the 'Hardware Phase'

Fifty years ago today — November 28, 1961 — North American Aviation won the prime contract to develop the Apollo Command & Service Module.


(Apollo-15 Command & Service Module, in lunar orbit. NASA image from Wikimedia Commons.)

This NASA history page has an interesting run-down of the competition and the source selection. The contract was critical to the overall Apollo effort:

The prime spacecraft contractor would develop and build the command module, service propulsion module, adapter (to fit the spacecraft to a space laboratory for earth-orbital flights and to the lunar landing propulsion section for lunar missions), and ground support equipment.


(Diagram of the Command Module interior. NASA image from Wikimedia Commons.)

While 14 companies received the request for proposal, in the final source selection North American Aviation competed against only General Dynamics Astronautics, General Electric, the Martin Company, and McDonnell Aircraft Corporation. Each company submitted a detailed technical and program management package in October 1961, which “were scrutinized and evaluated by more than a hundred specialists.”

The Martin Company actually had the highest aggregate rating from the source evaluation board, but North American Aviation had scored highest in technical qualifications and had “the longest record of close association with NACA-NASA and the most straightforward advance into space flight.” That apparently won the day for them, although Martin employees had been told — erroneously, as it turned out — on the 27th that they had won the contract.

With this contract, the Command & Service Module was the first part of the Apollo system to enter the “hardware phase.”

Happy Thanksgiving! Oh, and Some Space History

Comments Off on Happy Thanksgiving! Oh, and Some Space History

Wishing you and yours a most Happy Thanksgiving!

Walking the dog this morning, I thought about things for which I’m thankful — the list is long, and I’m sure I didn’t think of everything. More things are coming to mind even as I type this.

I think it’s good for us to pause, reflect, and express appreciation for what we have — especially family and friends — rather than being bitter and resentful over things we don’t have. The Apostle Paul wrote that he had learned how to be content in every situation;* I’m not quite there yet, but I hope to be.

So, may we all find things for which we can be truly thankful, today and every day.

[BREAK, BREAK]

Now, the promised “Space History”…

Twenty years ago today — November 24, 1991 — the Space Shuttle Atlantis lifted off from the Kennedy Space Center on a Department of Defense mission.


(DSP satellite being tilted to its predeployment position in the shuttle’s payload bay. NASA image.)

During mission STS-44, astronauts Frederick D. Gregory, Terence T. “Tom” Henricks, James S. Voss, Story F. Musgrave, Thomas J. Hennan, and Mario Runco deployed the third Defense Support Program (DSP) missile warning satellite.

Without going into too much detail, DSP satellites stare at the earth, looking for the infrared signatures of rocket exhaust that would indicate ballistic missile launches.

Which, if nothing else, perhaps we can all be thankful for eyes in the sky that are watching out for sneak attacks.
