Another “Space Watch” article…

While I’ve been lying low content-wise on the site here, I’ve been staying pretty busy at work. One of the many fun things I get to do is to look up historic events leading up to the Apollo moon missions, and then write a little bit about the event for the Space Foundation’s “Space Watch” monthly newsletter.

In this particular “Space Watch” article, titled Gordon’s Orbital Garbage Disposal and Rocket Herding Service,” I try to describe the activities of two brave astronauts during a Gemini mission fifty years ago. What they did gives the category of “space operations” an entirely different meaning, and shows just what kind of interesting and courageous explorers they were.

While many NASA fans seem to attribute the administration’s achievements to the idea of NASA itself, I’ve always felt it was the people within, such as Gordon and Conrad in this story, who really moved the agency forward toward the lunar missions and subsequent successes. This is not to downplay the mission controllers, engineers, and others who all played their part. Indeed, it’s the team, the people, who figure out how to overcome challenges, and then move ahead. But the astronauts in particular put their lives on the line during space missions. Whether it’s NASA, or in the future, one particular company or other that starts regular manned flights to space, the professionals called astronauts will still be the ones trading the ability to “fly” in space with the possibility of real, deathly, consequences.

With these thoughts in mind, I hope you enjoy Gordon’s Orbital Garbage Disposal and Rocket Herding Service.”

Gemini V

Last August was the 50th anniversary of the Gemini V mission. For this blog, the Gemini V mission begins a theme for a small series of stories about astronauts and their character. As my Apollo 50th Anniversary Moment article from August describes, astronauts are tough. They’re also smart and resourceful, traits Charles Conrad and Gordon Cooper displayed generally day-to-day, but especially useful for them throughout the Gemini V mission.

Why Gemini V for an Apollo 50th Anniversary series? It was NASA’s program to learn as much as they could about piloting, living, and surviving in space–things that were critical to know for successfully living through Project Apollo–NASA’s program to get astronauts to the moon. Space was new to everyone–Americans and Russians–and there was a lot to learn.

Gemini V was interesting for many reasons, including the few setbacks the astronauts faced. One particular setback would have radically cut the mission duration, but the astronauts faced the challenge very well. I described that one particular challenge, and how the astronauts handled it, in my article for the Space Foundation’s “Space Watch”: Eight Days or Bust–Gemini V.

There is no Clapper light switch in space…remember, it was over 50 years ago.

SpaceX’s CRS7 mission explodes

This Sunday morning, a Falcon 9 rocket was supposed to launch and deliver supplies to the International Space Station (ISS). And while SpaceX launched the rocket around 8:20 AM (MST) this morning, the resupply mission, CRS7, didn’t make it. The Falcon 9 exploded a little over 2 minutes into flight. There were mentions of an anomaly right before the explosion, but that word has little meaning to public understanding of what happened.

The mission was intended to get supplies and equipment to the ISS. Two days after launch, the Dragon resupply capsule would have rendezvoused with the ISS and the crew would have started unloading the slightly over 4000 pounds (nearly 2000 kilograms) of supplies, vehicle equipment, experiments, and more. Eight of Planet Labs’ cubesats were also aboard as cargo, and would have been deployed in the months after they had been transferred from the Dragon to the ISS.

After today, of course, none of that mission is possible. The question is, what will happen next? Some might say it’s a reflection of our character as a nation on how we act towards this accident. There are already a few people who are ready to take their “ball,” the taxpayers’ money, and go home. Sad to say, there are some who have been waiting for something like this to happen, and are ready to undercut the pile of work that has gone into not only NASA’s and SpaceX’s work, but Orbital Sciences’, Boeing’s, and Sierra Nevada, and quite a few others.

But, and I admit this as me being optimistic, I’d like to think there are a few more level-head people who will, as they did with Antares, note that this kind of thing is the price of working in space. Occasionally, especially with long tubes of fuel and complex machinery flying through the sky, things go “boom.” And then those same level-headed people will just turn around and continue working to get the U.S. a commercial rocket fleet–which would be a first of its kind in the world.

We already saw some wisdom in NASA’s approach when the Antares launch failure occurred. While bad for Orbital Sciences, the accident didn’t seem to cripple NASA’s ability to resupply the ISS, because there was still SpaceX’s Falcon rocket ready for use. If anything, this latest incident with SpaceX seems to be full of opportunities.

First, SpaceX has the chance to show its chops to perhaps do a quick-turnaround on this. The company has already said it wants to be able to launch their rockets quickly, so why not just get another one on the pad? Of course, the company and NASA would still be striving to figure out what happened with today’s rocket. But, isn’t part of this whole concept just to keep launching in spite of some hiccups?

Second, get more players involved with the business of launching. NASA basically whittled the field down to two resupply players, SpaceX and Orbital, because of money. But today’s lesson should be showing just how frail our space launch infrastructure is with even two launch systems resupplying the ISS. Get someone else in there. Heck, the United Launch Alliance might be able to pick up some slack on this, and in the process prove they can compete with the lower launch prices. It doesn’t even have to be through as complicated a contract vehicle as NASA’s Commercial Cargo.

Third, keep pushing government money out of the industry. If other political players are attempting to influence the future of humanity in the stars by taking funding away to get work done on a bridge to nowhere, then maybe that’s a sign that government might not be the best steward for fostering the space industry.

And, oh by the way, the more we do this kind of thing, the better our rockets will be.

In the end, I’d like to think some combination of these three options will happen. But I’ve also seen enough shenanigans to know that none of these options might ever happen because–politics. But for now I’m cheering NASA and all these companies to get up. Get up, keep showing how amazing your products are, and how smart and tough your engineers are, and ultimately ignore the whiners who want to take their ball and go home. You’re the ones on the ball court, not them.

The Starman Walking in the Sky

Some people actually look forward to reading my next Apollo 50th Anniversary Moment. So here it is–just a bit about Gemini IV and the first U.S.-conducted spacewalk–all in the monthly “Space Watch:” Gemini IV: There’s a Starman Walking in the Sky.

For those who don’t know, NASA’s Gemini program was a “bridge” program. Most of what the agency and its astronauts were accomplishing and learning with Gemini would eventually be applied to NASA’s Apollo and later programs. Space.com actually has a neat infographic showing some bits about the Gemini spacecraft, the “space food” the astronauts tested, and the hoped-for but never really pursued plans to keep the Gemini spacecraft in NASA’s space transportation inventory. It’s a fun look, and you can read all about it, Space.com.

And for fun, if you didn’t get the David Bowie reference to Starman, here’s a video of him playing the song from his album The Rise and Fall of Ziggy Stardust and the Spiders from Mars:

“Hold your fire.” SpaceX’s “Escape Pod”

When I first saw images of SpaceX’s test of their Dragon capsule’s pad abort test, the obvious nerd-quote going through my mind was “Hold your fire. There’s no lifeforms.” Which was true for the test. And if you don’t get the reference, please just search on the net, roll your eyes, and sigh. For the rest of you, you’re welcome!!

The big news, then, is that on May 6, 2015, SpaceX conducted the first test of the abort system for their capsule, and it looks like it worked. It also looked really cool. But why conduct this nifty-looking test in the first place? In plain English, SpaceX would like to build space capsules to take humans into space. The capsule they’re advertising to accomplish this feat is the Dragon Version 2 (v2). The pad abort test they conducted this last week was a step towards actually building and operating a manned capsule.

The test is a milestone, a critical step, required by NASA of SpaceX as a part of NASA’s Commercial Crew Program. The program’s goal is to ferry people to and from the International Space Station (ISS) using commercially-built space capsules from the U.S. (for more information about this interesting program, click here). This particular milestone begins testing the Dragon’s escape system, which is supposed to keep astronauts safe in case something goes wrong with the rocket beneath it–such as going kablooey like Orbital’s Antares rocket did in October 2014. If such an explosive event were to occur, then the capsule needs to lift off from the rocket body quickly, which it looks like the Dragon does. See the video of the test below and then read on.

According to SpaceX, the capsule accelerated from rest to 100 mph (161 kmh) in 1.2 seconds. It eventually reached a top speed of 345 mph (555 kmh), and was supposed to fly as high as 5.000 ft (1524 meters). It took eight liquid-fed SuperDraco engines to move the capsule that high and that quickly. Each engine puts out 15,000 lbs of thrust. The same engines would normally be used for Dragon capsule landing after atmospheric re-entry.

The capsule does separate from the trunk (the white cylinder it’s attached to), flips, and then pops out a few parachutes to float down to the Atlantic Ocean. The Dragon capsule is supposed to be able to do this type of maneuver throughout a rocket flight, from launch pad through orbit. SpaceX notes that, based on data from the 270 sensors mounted on the capsule and possibly on the dummy sitting inside, a human would have come through just fine. But this is a single test, and there’s more testing to come for SpaceX. SpaceX is aiming to get the Dragon crew-rated and actually manned by humans traveling in it to and from the ISS come 2017. They seem to be making great progress.
