First Asteroid Mission, Triumphant Despite Many Troubles

Ten years ago today — May 9, 2003 — Japan launched a daring asteroid sample-return mission from the Uchinoura Space Center, atop an M-5 rocket.

Originally called Muses-C, Hayabusa (“Falcon”) was a difficult mission to begin with, but experienced a series of setbacks that made its ultimate success all the more impressive.

  • In late 2003, a large solar flare degraded the spacecraft’s solar panels, reducing the power available to its ion engines. The original rendezvous date in early summer 2005 was pushed back to September.
  • On July 31, 2004, Hayabusa’s X-axis reaction wheel failed.
  • The spacecraft successfully rendezvoused with 25143 Itokawa (1998 SF36) — an asteroid  about as big as three football stadiums at 550 x 180 meters (1800 x 590 feet) — on September 12, 2005. Hayabusa established itself in a heliocentric orbit for station-keeping about 20 km (12.4 mi) from the asteroid.
  • On October 3, 2005 Hayabusa’s Y-axis reaction wheel failed, leaving its attitude control subsystem operating only on “one reaction wheel and two chemical thrusters.”
  • Hayabusa mapped the asteroid’s surface in two phases, then began descent operations. During the second touchdown rehearsal on November 12th, the spacecraft released a “lander/hopper” called Minerva; unfortunately, “the release was at a higher altitude than planned…. and it is believed Minerva moved off into space without landing.”
  • A week later, on November 19, Hayabusa again descended toward the asteroid, and released a “target marker” before contact was lost as it fell to the surface.

Later telemetry indicated that Hayabusa hit the surface at 20:40 UT 19 November (5:40 a.m. JST 20 November) at roughly 10 cm/sec and bounced. It bounced again at 21:10 and then landed at 21:30 within about 30 meters of the target marker. At 21:58 (6:58 a.m. JST 20 November) it was commanded to make an emergency ascent. The craft remained on the surface for about half an hour but did not collect a sample. This was the first ever controlled landing on an asteroid and first ascent from any other solar system body except the Moon.

  • On November 25, Hayabusa touched down again, and fired two “sampling bullets” at the surface. Telemetry could not verify that they actually fired; nevertheless, Hayabusa lifted off.
  • On December 9, ground controllers lost contact with the spacecraft, “presumably because of torques caused by a thruster leak which altered the pointing of the antenna.”
  • Controllers restored communication in March 2006, and learned over the next several months that the spacecraft’s status was somewhat grim: low on fuel, two out of three reaction wheels inoperative, plus 4 out of 11 batteries had also stopped working. The spacecraft’s degraded solar cells and batteries were still sufficient to maintain thrust and attitude control with its xenon ion engine, and in April 2007 it started its journey Earth-ward.

When Hayabusa was a little outside the Moon’s orbit, it released its sample return capsule, which de-orbited on June 13, 2010 and landed near Woomera, Australia.

Subsequent examination of the sample return capsule showed that there were roughly 1500 dust particles, presumably from asteroid Itokawa.

Well done, Hayabusa!

New ASIMOV’S, with My Story, ‘What is a Warrior Without His Wounds?’

Here’s a look at the cover of the July issue of Asimov’s Science Fiction, which should be available on newsstands and/or in bookstores later this week:


(Asimov’s, July 2013.)

As noted in the title, I have a novelette (i.e., a story of a certain length) in this issue. The story opens as follows:

Miroslav did not expect to find a Colonel waiting for him when he returned from physical therapy. The officer was looking out the window; Miroslav came to sluggish attention, unused to his ill-fitted prosthetic leg.

The stranger turned away from the window and regarded Miroslav’s awkward pose. “Please, Captain,” he said, his voice heavy though he smiled and nodded, “stand at ease, or sit if you prefer.”

Miroslav shifted his single crutch a little, careful not to throw his balance off. He would not sit unless the Colonel did so, even though his muscles quivered as if he had just completed a twenty-kilometer forced march.

Would they send a high-ranking officer to discharge him? Any nurse could have delivered the paperwork; it would be less humiliating.

“How is your recovery?” the Colonel asked. “Are you receiving adequate treatment? Are you progressing well?”

Miroslav acquiesced to the small talk. “I am stronger,” he said. He stood on his own for a second and tapped his false leg with the crutch. As he put the crutch back down, he lifted his prosthetic left arm. “I am not … as capable as I once was.”

If you get a chance to read it, I hope you find the story worth your while.

Some Perspective on Fan Mail

Or on fan e-mail, as it were.

Having only published a few stories, I don’t get much in the way of reader feedback, whether by e-mail, or here on the blog, or in person. When it does come — as when a young fellow asked for my autograph at a recent convention, or yesterday when a young lady wrote in about one of the stories I had in Asimov’s last year — it can be both refreshing and humbling.

I must be getting old...
(“I must be getting old…” by idogcow, from Flickr under Creative Commons.)

It just so happens that last night, barely an hour after reading yesterday’s very complimentary e-mail, I read something else that helps put such things in perspective. My leisure reading of late has been The Best of Gene Wolfe, a collection of his short fiction, and in the afterword to “The Detective of Dreams” Mr. Wolfe writes,

I will not lecture you on Jesus of Nazareth, but I advise you to find [G.K.] Chesterton’s The Everlasting Man. In [“The Detective of Dreams”] I asked you to consider that everlasting man’s short fiction. Fans have written me to say that this or that story stayed with them for days. Each letter makes me proud and happy. In my happiness and pride, I am prone to forget that there was once a storyteller from Galilee whose stories have stayed with us for millennia.

I like that very much.

So as much as I appreciate knowing that someone has read and appreciated something I wrote, I must recognize that, as Audio Adrenaline sang, I’m “never gonna be as big as Jesus.”

And that’s okay.

P.S. I also recommend The Everlasting Man, which is interesting and at times fascinating. I listened to the audiobook, but I admit that to me the text came across as almost too complex for audio. I would like to find a good print copy, in order to consider Chesterton’s arguments in their proper depth. GWR

New Issue of LORE, with My Story, ‘A Star That Moves’

Now available at an Internet near you: the latest edition of LORE with one of my short stories in it!


(Lore, Volume 2, Number 3.)

Here’s the opening:

A little paranoia is healthy in a soldier, and Gaius Antonius Marcellus was a good soldier.

Marcellus did not question the prickly feeling of being targeted. He reacted to it. That reflex had left him with scratches instead of gaping wounds as he rose through the Legion ranks; it saved him from many Gallic spears in his campaigns as a Centurion; and it even warned him of political dangers through this first year as Legatus Legionis, the garrison commander. It had never failed him.

For half a month he had felt it — the hairs alert on the back of his neck — but he could not find the source. And facing the unknown was worse than facing an enemy’s sword.

And, just so you know that this is science fiction rather than fantasy, a tiny spoiler: the alien spacecraft shows up in the next paragraph.

Exploring the Evolution of Galaxies

Ten years ago today — April 28, 2003 — a Pegasus XL rocket carried a small spacecraft to probe the origin of stars and galaxies.


(A 2012 GALEX composite image of the Andromeda galaxy. NASA/JPL-Caltech image.)

Called GALEX, for GALaxy Evolution eXplorer, the spacecraft’s primary instrument was a telescope tuned to the ultraviolet part of the spectrum. With its mission now extended beyond the original 29-month timeline, GALEX is conducting “an all-sky imaging survey, a deep imaging survey, and a survey of 200 galaxies nearest to the Milky Way” in order to explore the origins of heavy elements, stars, and galaxies. You can find more information about the mission, including many stunning images, on this page

For more down-to-earth mapping purposes, on this date 5 years ago India launched CartoSat 2A, a remote-sensing satellite, along with 9 smaller spacecraft, from the Sriharikota launch center on a PSLV 9 rocket. Urban and rural planners use CartoSat’s data.

Shuttle, Soyuz, and Space-Based Navigation

Twenty years ago today — April 26, 1993 — the Space Shuttle Columbia launched from the Kennedy Space Center on an international Spacelab mission.


(Spacelab D-2 in the shuttle payload bay. Note the lightning flashes in the clouds below. NASA image.)

The STS-55 crew consisted of U.S. astronauts Steven R. Nagel, Terence T. Henricks, Jerry L. Ross, Charles J. Precourt, Bernard A. Harris Jr., and Ulrich Walter, plus German astronaut Hans W. Schlegel. The shuttle carried the second of the German-built reusable Spacelab modules, and the crew spent 9 days in space conducting a variety of experiments in the laboratory. One highlight of the mission was the first IV established in orbit, in which Dr. Harris “inject[ed] Schlegel with saline as part of study to replace body fluids lost during adaptation to weightlessness.”

Then, on this date 10 years ago, astronaut Edward T. Lu launched from the Baikonur Cosmodrome on mission Soyuz TMA-2, making him the first U.S. astronaut to serve as the Flight Engineer of a Soyuz spacecraft. The spacecraft commander was cosmonaut Yuri I. Malenchenko, and their destination was the International Space Station where they became the Expedition 7 crew.

Finally, 5 years ago today — April 26, 2008 — a Soyuz-Fregat rocket launched from Baikonur carrying GIOVE-B (Galileo In-Orbit Validation Element-B), the second of two test spacecraft for the European Union’s own fleet of navigational satellites.

Soft X-Rays and a Data Relay

Twenty years ago today — April 25, 1993 — the first satellite completely sponsored by the Department of Energy launched on a Pegasus booster, dropped from the wing of NASA’s B-52.


(ALEXIS satellite artist’s conception. NASA image from Wikimedia Commons.)

The Array of Low Energy X-Ray Imaging Sensors (ALEXIS) satellite’s primary instrument was an X-ray telescope array tuned to “ultrasoft” X-rays for making a sky map in that part of the electromagnetic spectrum, as well as the “Blackbeard” VHF receiver “for studying the effect of lightning and electromagnetic impulse from exploding [nuclear] devices on the ionospheric transmission.”

During its flight, one of the satellite’s solar array paddles was damaged, and controllers could not establish contact with the spacecraft for 3 months. Once they established contact, they had to develop specific attitude control procedures to bring the satellite under control, after which the spacecraft performed well although “the astronomy data needed a full pointing and aspect solution in order to be interpreted.”

And, to complete the promise implied by the title of this post: 5 years ago today — April 25, 2008 — China launched its first data-relay satellite, Tianlian 1, on a Long March 3C rocket from Xichang Launch Center.

Neurolab, the Last Spacelab Mission

Fifteen years ago today — April 17, 1998 — the Space Shuttle Columbia launched from the Kennedy Space Center on a unique scientific mission.


(The Spacelab module in the Shuttle cargo bay during mission STS-90. NASA image from Wikimedia Commons.)

The STS-90 crew — Richard A. Searfoss, Scott D. Altman, Richard M. Linnehan, Dafydd Rhys Williams, Kathryn P. Hire, Jay C. Buckey, and James A. Pawelczyk — spent just over 2 weeks in space, operating the “Neurolab” which

targeted one of the most complex and least understood parts of the human body — the nervous system. The primary goals were to conduct basic research in neurosciences and expand understanding of how the nervous system develops and functions in space. Test subjects were crew members and rats, mice, crickets, snails and two kinds of fish.

The crew conducted most of the experiments in the European Space Agency’s pressurized Spacelab module, which flew for the last time on this mission.

The mission might have ended a week early because of a problem with the Regenerative Carbon Dioxide Removal System, but ground-based engineers guided the crew through bypassing a “suspect valve” to enable them to stay on orbit.

Buy a Book, Help My Teacher’s Injured Son

Serious business here: Tomorrow — Wednesday, April 10, 2013 — a “book bomb” is in the works to push two of Dave Wolverton’s books, both written under his pen name of David Farland, to help cover the medical costs for his critically-injured 16-year-old son.


(Ben Wolverton, on a happier day.)

The particulars:

  • I’ve known Dave Wolverton since 2004, when we sat next to one another at Orson Scott Card’s Literary Boot Camp. Dave was already a professional writer and bestselling author, and took the course to pick up teaching tips. Then in 2008, I attended Dave’s Novel Writing Workshop.
  • Last week Dave’s son Ben was in a serious long-boarding accident. I can barely fathom the extent of his injuries: “severe brain trauma, a cracked skull, broken pelvis and tail bone, burnt knees, bruised lungs, broken ear drum, road rash.”
  • As of late yesterday, Ben was still in a coma.
  • Since Dave is a self-employed writer, and medical insurance for self-employed people can be problematic, they have no insurance.

Several folks close to the family have organized a book bomb — i.e., they’re asking people to coordinate their purchases to call special attention to select works — focused on Dave’s novel Nightingale and his writing book Million Dollar Outlines. I was one of the “beta readers” for Nightingale, and it’s a terrific story.


(Dave’s young adult contemporary fantasy novel.)

So if you happen to be in the market for a contemporary fantasy novel and/or a guide to putting together top-notch stories of your own, please consider buying one (or both) on this Wednesday to support Dave and his son Ben. And if you’re on Facebook, you can join the event page here.


(Some of Dave’s writing instruction, available in book form.)

___

If you already own (or don’t want) the books, but still want to donate, you can send money to their family at this link.

UPDATE, Wednesday morning: They’ve set up a website about Ben and his status, at http://www.helpwolverton.com/.

Atmospheric Science and Two Space Firsts

On this date, 15 years apart, two trailblazing (so to speak) female astronauts made historic space flights.


(Charlotte, North Carolina, photographed at night from STS-56. NASA image.)

Twenty years ago today — April 8, 1993 — the Space Shuttle Discovery launched from Kennedy Space Center carrying two science payloads. The STS-56 crew consisted of astronauts Kenneth D. Cameron, Stephen S. Oswald, C. Michael Foale, Kenneth D. Cockrell, and the first Hispanic woman to fly in space, Ellen Ochoa. The primary payload was the Atmospheric Laboratory for Applications and Science (ATLAS, in its second iteration, ATLAS-2), which was “designed to collect data on [the] relationship between [the] sun’s energy output and Earth’s middle atmosphere and how these factors affect ozone layer.” The crew also deployed and recovered the SPARTAN-201 free-flying science package, which examined the sun’s corona and the solar wind.

Also on this date, in 2008, Soyuz TMA-12 launched from the Baikonur Cosmodrome, carrying cosmonauts Sergei A Volokov and Oleg D. Kononenko, plus South Korean Yi So-Yeon, to the International Space Station. Yi was South Korea’s first astronaut, having been selected from 36,000 applicants. Volokov and Kononenko stayed aboard the ISS when Yi and the former ISS crew returned to Earth on April 19th.
