Things have been moving fast for NASA in recent weeks, culminating in President Obama’s inspiring speech at Kennedy Space Center on Thursday. I haven’t commented on the new direction for the US space agency’s direction thus far as I’ve needed some time to digest the ramifications of these plans. But generally, I’m positive about the scrapping of the moon goal in favor of a manned asteroid mission (by 2025) and Mars some time around 2035.
But it hasn’t been easy, especially after the Ares I-X test launch in October 2009.
The Ares I-X was the first new NASA manned vehicle my generation has seen take to the skies (I was only one year old when the first of the shuttle fleet launched, beginning nearly 30 years of low-Earth orbit operations, so that doesn’t count). Despite criticism that this test flight was nothing more than old tech dressed up as a sleek “new” rocket, I was thrilled to see it launch.
The end product didn’t matter on that day. Sure, we’ve been to the Moon before, but it just seemed like the best plan on the table. I was inspired, I felt excited about our future in space. Seeing how astronauts live and work on the lunar surface, using it as a stepping stone for further planetary exploration (i.e. Mars) seemed… sensible. Expensive, but sensible
But the overriding sentiment behind Obama’s new plans was that we’ve been there before, why waste billions on going back? Continuing with the bloated Constellation Program would have used up funds it didn’t have. Cost overruns and missed deadlines were already compiling.
So, the White House took on the recommendations of experts and decided to go for something far riskier than a “simple” moon hop. Things going to plan and on schedule, in the year 2025 we’ll see a team of astronauts launch for a much smaller and far more distant target than the moon.
The asteroid plan has many benefits, the key being that we need to study these potentially devastating chunks of rock up close. Should one be heading in the direction of Earth, it would be really nice to have the technological ability to deal with it. A manned mission may be necessary to send to a hazardous near-Earth asteroid. Think Armageddon but with less nukes, no Bruce Willis, but more science and planning. Besides, if a rock the size of a city is out there, heading right at us, I’m hopeful we’ll have more than 18 days to deal with the thing.
My Discovery News colleague Ray Villard agrees:
“A several month-long human round trip to an asteroid will test the sea legs of astronauts for interplanetary journeys. And, asteroids are something we have to take very seriously in coming up with an Earth defense strategy, so that we don’t wind up going extinct like the dinosaurs.”
Possibly even more exciting than the asteroid plan is what — according to Obama — will happen ten years after that: a manned mission to Mars. I can’t overemphasize my enthusiasm for a mission to the Red Planet; that will be a leap for mankind like no other. Granted, there is plenty of criticism flying around that we need to live on the moon first before we attempt to land on Mars, but looking at the new plan, we won’t be actually landing on Mars any time soon. A 2030′s mission to Mars will most likely be a flyby, or if we’re really lucky, an orbital manned mission.
And that’s why going to an asteroid will be a good first step. Spending months cramped inside a spaceship with a handful of crewmates will likely be one of the biggest challenges facing man in space, so popping over to a near-Earth asteroid first is a good idea. A Mars trip could take over a year (depending on the mission). Now, this is where technological development sure would help.
If NASA can plough dedicated funds into new technologies, new life support and propulsion systems can be developed. Those two things will really help astronauts get places quicker (avoiding boredom) and live longer (avoiding… death). For the “living longer” part, there appears to be genuine drive to increase the life of the space station and do more impressive science on it. As it’s our only manned outpost, perhaps we’ll be able to use it for what it’s designed for.
There are a lot of unknowns still, and Obama’s Thursday speech certainly wasn’t NASA’s silver bullet, but it’s a start. Allocating serious funding for space technology development whilst setting the space program’s sights on going where no human has been before will surely boost enthusiasm for space exploration. In fact, I’d argue that this is exactly what NASA should be doing.
Although I was dazzled by the Ares I-X, I can see that continuing with Constellation would have been a flawed decision. Launching a manned mission to explore an interplanetary threat sounds risky, but considering that asteroids are the single biggest cosmic threat to civilization, it sure would be useful to know we have the technology to send astronauts to asteroids, perhaps even dealing with a potential threat in the near future.
