Astronauts William F. Readdy, Terrence W. Wilcutt, Jerome Apt, Thomas D. Akers, Carl E. Walz, and John E. Blaha flew up to Mir as part of mission STS-79. Atlantis dropped off John Blaha and picked up Shannon Lucid for her return to earth after a record-setting 188 days in space (179 aboard the Russian station).

STS-79 marked the first time a shuttle was rolled back to the Vehicle Assembly Building twice because of hurricane warnings: first because of Hurricane Bertha, and again because of Hurricane Fran. Thus, the rollout picture above.

Comments Off on First Orbital Mercury Test Flight

A half-century ago today — September 13, 1961 — the unmanned Mercury-Atlas-4 (MA-4) test flight launched from Cape Canaveral.

MA-4 was the first orbital test flight of the Mercury program; the previous flights had all been sub-orbital.

The payload consisted of a pilot simulator (to test the environmental controls), two voice tapes (to check the tracking network), a life support system, three cameras, and instrumentation to monitor levels of noise, vibration and radiation. It demonstrated the ability of the Atlas rocket to lift the Mercury capsule into orbit, of the capsule and its systems to operate completely autonomously, and succeeded in obtaining pictures of the Earth.

After one orbit, the capsule splashed down east of Bermuda, where it was recovered for examination.

Space History Double Shot: Gemini-11 and STS-48

Comments Off on Space History Double Shot: Gemini-11 and STS-48

Forty-five years ago today — September 12, 1966 — astronauts Charles “Pete” Conrad, Jr. and Richard F.Gordon, Jr., launched from Cape Canaveral on the Gemini-11 mission.

Gemini-11 mission objecttives were “to achieve a first orbit rendezvous and docking with the Agena target vehicle, to accomplish two ExtraVehicular Activity (EVA) tests, to perform docking practice, docked configuration maneuvers, tethered operations, parking of the Agena target vehicle and demonstrate an automatic reentry.” The 3-day mission also carried several experiments.

Gemini-11 marked the first time two tethered spacecraft were rotated to impart a gravity-like acceleration.

The hatch was closed at 9:57 a.m. [on September 14] and shortly afterwards the spacecraft were undocked and Gemini 11 moved to the end of the 30 meter tether attaching the two spacecraft. At 11:55 a.m. Conrad initiated a slow rotation of the Gemini capsule about the GATV which kept the tether taut and the spacecraft a constant distance apart at the ends of the tether. Oscillations occurred initially, but damped out after about 20 minutes. The rotation rate was then increased, oscillations again occurred but damped out and the combination stabilized. The circular motion at the end of the tether imparted a slight artificial “gravitational acceleration” within Gemini 11, the first time such artificial gravity was demonstrated in space. After about three hours the tether was released and the spacecraft moved apart.

Twenty-five years later, on this date in 1991, the Space Shuttle Discovery launched from the Kennedy Space Center on mission STS-48. Astronauts John O. Creighton, Kenneth S. Reightler, Jr., Mark N. Brown, Charles D. Gemar, and James F. Buchli deployed the Upper Atmosphere Research Satellite (UARS).

UARS was designed to operate for three years, to “make the most extensive study ever conducted of the Earth’s troposphere, the upper level of the planet’s envelope of life sustaining gases which also include the protective ozone layer.” The spacecraft was decommissioned in December 2005.

Unfortunately, UARS has been in the news recently: the 14,500-pound observatory is expected to fall back to earth later this month in an uncontrolled reentry.

Five years ago today — September 9, 2006 — the Space Shuttle Atlantis launched from the Kennedy Space Center on a mission to the International Space Station.


(Joseph R. Tanner waves at Heidemarie M. Stefanyshyn-Piper during their spacewalk. NASA image.)

Mission STS-115 was the latest ISS construction mission. U.S. astronauts Brent W. Jett, Jr., Christopher J. Ferguson, Heidemarie M. Stefanyshyn-Piper, Joseph R. (Joe) Tanner, and Daniel C. Burbank, along with Canadian astronaut Steven G. MacLean, installed the P3/P4 truss, a major structural element that included additional solar panel arrays.

Here’s the station before the P3/P4 truss was installed:

From the Land of the Rising Sun, a Satellite to Study the Sun

Comments Off on From the Land of the Rising Sun, a Satellite to Study the Sun

Twenty years ago today — August 30, 1991 — the Yohkoh solar astronomy satellite launched from Kagoshima Space Center, Japan.


(Artist’s conception of the Yohkoh spacecraft. NASA image.)

Yohkoh was originally named “Solar-A,” and was a joint venture between Japan, Great Britain, and the US. “Yohkoh” means “sunlight” in English.

The Yohkoh mission lasted a decade, until an anomaly ended the satellite’s life. According to this Marshall Space Flight Center page,

Yohkoh suffered a spacecraft failure in December 2001 that has put an end to this mission. During the solar eclipse of December 14th the spacecraft lost pointing and the batteries discharged. The spacecraft operators were unable to command the satellite to point toward the sun.

If you have a child interested in such things — or if you yourself have a childlike interest in such things — you can build your own model Yohkoh satellite, using actual satellite blueprints.

And in other space history, on this date 50 years ago the U.S. launched Discoverer-29 on a Thor rocket out of Vandenberg AFB. According to this Wikipedia page, Discoverer-29 was the first of the KH-3 series of reconnaissance satellites launched by the NRO in the Corona program.

Suborbital Apollo-Saturn Test Flight, and Bill Dana Goes Supersonic

Comments Off on Suborbital Apollo-Saturn Test Flight, and Bill Dana Goes Supersonic

Forty-five years ago today — August 25, 1966 — NASA launched another suborbital Apollo-Saturn vehicle to test Command & Service Module systems in advance of manned Apollo launches.


(AS-202 launch. NASA image.)

AS-202‘s flight objectives were to verify the Saturn 1B launch vehicle’s integrity, loads, and performance, and to evaluate the separation system, emergency detection, and heatshield of the Apollo spacecraft.

Mission controllers fired the CSM’s engines multiple times to test their rapid restart capabilities, accelerating the capsule for reentry to test the heatshield. It performed very well: “Maximum temperature of the spacecraft exterior was calculated at about 1500 deg. C, temperature inside the cabin was 21 deg. C (70 F).”

Jump ahead five years in time …

On this date in 1971, NASA pilot William “Bill” Dana made the first supersonic flight in the M2-F3 lifting body.


(NASA lifting body pilots with M2-F3 in the background. NASA image.)

Last November, I blogged about Dana making the first flight in the M2-F3. I likely will continue posting occasional references to Dana’s flights, because he’s one of the most interesting people I ever met (during my first USAF assignment, we were both on the Flight Readiness Review Committee for the very first launch of the Pegasus system). If you want to know more about him, check out his Wikipedia page.

Ranger-1

Comments Off on Ranger-1

Fifty years ago today — August 23, 1961 — Ranger-1 launched from Cape Canaveral on an Atlas-Agena rocket.


(Ranger-1 spacecraft. NASA image.)

Ranger-1 was designed as a pathfinder mission to test components for future lunar and planetary missions. It also carried scientific instruments such as telescopes, particle detectors, a magnetometer, etc., to “study the nature of particles and fields in interplanetary space.”

The Atlas rocket put Ranger-1 in a “parking orbit,” but the Agena upper stage did not restart. Ranger-1 separated from the Agena and ended up tumbling in a low Earth orbit, re-entering the atmosphere a week after it was launched. Thus the mission was counted a partial success: “much of the primary objective of flight testing the equipment was accomplished but little scientific data was returned.”

A FAST Launch, and the Hugo Awards

Comments Off on A FAST Launch, and the Hugo Awards

Fifteen years ago today — August 21, 1996 — a Pegasus-XL rocket launched the “Fast Auroral SnapshoT explorer” to study how particles funneled through the Earth’s magnetosphere produce auroras.

(FAST satellite, after installation of its body-mounted solar panels. NASA image.)
FAST was placed in a polar orbit, the better to observe auroras, in an interesting configuration: the craft is spin-stabilized but its spin axis is perpendicular to its orbital track, so it would appear to roll or “cartwheel” through space. Its Pegasus launch vehicle originated out of Vandenberg AFB, and was carried to the Pacific drop zone by its L-1011 mothership.

In more recent news — tangentially space-related, since the Hugo Award features a stylized rocket ship — last night my friend Mary Robinette Kowal won the Hugo for Best Short Story: “For Want of a Nail”, which appeared in the September 2010 issue of Asimov’s. The complete list of Hugo winners is available here.

Several other writing friends — Rachel Swirsky, Aliette de Bodard, and Eric James Stone — were also nominated for Hugos, and two — Larry Correia and Saladin Ahmed — were nominated for the Campbell Award … which is pretty awesome even though they didn’t win.

But, as I posted to Larry on Facebook, even though he didn’t win I’m pretty sure he’s the only nominee with a song written about his book.

Comments Off on ADEOS (Midori) and the First Frenchwoman in Space

Fifteen years ago today — August 17, 1996 — the Japanese launched the first of a series of environmental remote sensing satellites, and the Russians launched a mission to Mir that included the first female French astronaut.


(Artist’s conception of ADEOS spacecraft. JAXA image.)

ADEOS, which was later renamed “Midori,” was the ADvanced Earth Observation Satellite and was launched from Tanegashima Space Center on an H-2 rocket. The spacecraft operated until mid-1997, measuring winds, ocean surfaces temperature, atmospheric aerosols, ozone, and greenhouse gases. You can read more about the first ADEOS/Midori spacecraft on this JAXA page.

And Soyuz TM-24 launched from the Baikonur Cosmodrome atop a Soyuz-U launch vehicle, bound for the Mir space station. Russian cosmonauts Valery G. Korzun and Alexander Y. Kaleri flew on this mission with Claudie Andre-Deshays, the first French woman in space.

Comments Off on Explorer-12 and Meteor/TOMS

Two bits of space history today.

First, 50 years ago, Explorer-12 was launched from Cape Canaveral on a Thor-Delta rocket. Part of the extensive Explorer series, Explorer-12 was the first of a sub-series of four satellites orbited to “measure cosmic-ray particles, trapped particles, solar wind protons, and magnetospheric and interplanetary magnetic fields.”


(Model of the Explorer-12 satellite, on display at the Udvar-Hazy Center of the National Air & Space Museum. NASM image.)

And then 20 years ago a U.S. meteorological instrument — a Total Ozone Mapping Spectrometer (TOMS) — was for the first time launched as part of a Soviet satellite. The Meteor/TOMS launched from Plesetsk on a Tsiklon-3 (read, “Cyclone-3”) rocket.
