Earlier this month, NASA tested a key safety system on its new Orion spacecraft
in the sky above Florida.
In a simulated
emergency, the spacecraft aborted a take-off and split off from the speeding
rocket; propelling itself safely away.
The test was a key
milestone in NASA’s ambitious plan to return astronauts to the moon.
Mark Kirasich
is the NASA Program Manager for Orion at the Johnson Space Center in Houston,
Texas.
Mark Kirasich: You look at it from the outside and you say, "boy, that's the
same shape as Apollo." And it is. And the reason it is because we learned
the Apollo guys had the shape right. But you look underneath the skin and just
about every other aspect of Orion is different.
Hari Sreenivasan: Kirasich took me inside a full-scale model of the
spacecraft that NASA uses to study how the crew interacts with the ship and its
systems.
Mark Kirasich: Come on in and watch your step and welcome to the inside of an
Orion spacecraft.
Hari
Sreenivasan: So
four people are going to ride in this?
Mark Kirasich: Yes, yes. And by the capsule standards our astronaut team will
tell you this is quite a roomy spacecraft.
Hari
Sreenivasan: This
is roomy?
Mark Kirasich: This is roomy. You also have to remember in space everything is a
floor. Everything is a ceiling. So you can sleep on the walls you can walk on
the ceiling.
Hari
Sreenivasan: The
Orion is built by aerospace company Lockheed Martin and it’s designed to
support a crew for weeks at a time.
Mark Kirasich: Snake your way in like this.
Hari
Sreenivasan: Okay
Mark Kirasich: And unlike the spacecrafts used in the Apollo missions, it’s
flexible for astronauts of all sizes.
Hari
Sreenivasan: Oh,
wow!
Mark Kirasich: These seats, this cockpit's designed for what we call 5 percent
female, a very small woman to a ninety fifth percentile male, a very large man.
Hari
Sreenivasan: The
Orion capsule is key part of NASA’s Artemis program. Named after the twin
sister of the Greek god Apollo, Artemis will be a sequence of missions starting
with a flight with no crew in 2020, a flight with a crew in 2022 that will
orbit the moon, and then a 2024 mission that will land humans on the moon’s
south pole.
Unlike the Apollo
program, Artemis aims to establish a sustained presence on the moon, and set
the stage for further exploration to Mars.
Jeff Radigan
is the lead flight director for Artemis 2, the first flight with astronauts in
2022.
Jeff Radigan: It's really a stepping stone. One mission after the other
building on capability.
Hari
Sreenivasan: OK so
some people are gonna watch it and say look we did
that 50 years ago why do it again? Why go back?
Jeff Radigan: You know we haven't been back to the moon in 50 years and it's out
there waiting for us it's out there with so much we've discovered over the last
50 years with the unmanned spacecraft that have gone on there really gives us
the opportunity to go back and then stay there.
Hari Sreenivasan: Radigan points to the 2009 discovery of water on the
moon as a key resource to support long-term habitation and future exploration.
It could be harvested to drink, turned into oxygen for breathing, and the
hydrogen it contains could be used as rocket fuel.
The end of the Apollo
lunar missions in 1972, did not mark the end of astronauts in space for NASA.
The space shuttle program flew 135 missions between 1981 and 2011. Its
successes included launching scientific instruments like the Hubble Telescope
and helping build the International Space Station, or ISS.
But the program also
suffered two catastrophes that killed 14 astronauts: the Challenger, which
blew-up just after lift-off in 1986, and the Columbia, which disintegrated
reentering the Earth’s atmosphere in 2003.
Since the shuttle
program ended, NASA has relied on the Russian Soyuz rocket to transport
astronauts to the ISS, and private companies, like SpaceX, to carry supplies
and hardware.
Meanwhile, the space
station has been continuously occupied by an international group of astronauts
since November 2000.
Mark Kirasich: We've learned how to live and work in space for very long periods
of duration. We, we've learned how to keep people healthy, how to exercise the
kinds of foods to take so people can survive on very long missions in space.
Hari Sreenivasan: So we take those lessons and we say this is
what it's going to take if you want to live on the moon and work on the moon?
Mark Kirasich: Yes correct. While we are in lower orbit, we're still only a
couple hours away, we're just a couple hundred miles away from Earth. Now these
missions were about to embark on are hundreds of thousands of miles away, five
day trips. There is no two hour emergency ride home to Earth. So we have to
learn how to become less reliant on the earth.
Hari
Sreenivasan:
Whether or not America should embark on a new moon mission has been subject to
changing political forces.
In 2004, President
George W. Bush directed NASA to return to the moon. But in 2010, the Obama
administration scrapped the mission for being over budget and behind schedule,
focusing instead on a future mission to mars. In 2017, the Trump administration
pivoted back to the moon, targeting 2028 for the mission.
Then earlier this year,
the administration sped up the timetable.
Vice President Mike Pence: It is the stated policy of
this administration and the United States of America to return American
astronauts to the Moon within the next five years.
Hari
Sreenivasan: What
happens when you scoot up the deadline? That's a lot of pressure on the engineers
and everyone else that was planning on something way down the line, right?
Jeff Radigan: You know it changes your schedule obviously.
There's always gonna be pressure to get your job done
as well as you can. But that's balanced by having the resources to do it
right. And so I think we've done a pretty good job at NASA of trying to
explain that equation to the administration and to say absolutely we can
support 2024 we'd love to support 2024. We're all on board with that. Now
here's how we would do it and here's the resources it would take to get
there.
Hari
Sreenivasan:
So do you have the resources that you need now?
Jeff Radigan: So I appreciate the administrator you know
working with Congress and the administration to get the resources right. And I
applaud the administrator for saying that's going to take more money and I know
that folks are working very hard to make that happen.
Hari
Sreenivasan: NASA
believes it will take an additional 4 to 6 billion dollars a year over the next
five years, on top of its roughly 21 billion dollar annual budget to meet the
2024 lunar deadline. Taking that potential increase into account, the agency’s
budget is around half of one percent of all federal spending.
While that may sound
like a lot, NASA is actually trying to do more with less. At the height of the
Apollo program in the mid-1960s, federal spending on NASA accounted for roughly
four percent of the budget.
Adding to financial
pressure, NASA has been plagued with cost overruns on several key components,
including the space launch system, or SLS, the large
rocket that will send the Orion spacecraft into lunar space.
A 2018 Inspector General
report found that Boeing, which is making the SLS rocket, will likely spend
nearly double the budgeted amount, while delivering the rocket more than two
and a half years late.
Mark Kirasich
says NASA needs to find a way to entice private industry to invest in space
exploration.
Mark Kirasich: So right now we're working on commercializing the International
Space Station. Tourist sorts of things, scientific endeavors. And the moon
offer some special opportunities. Mining on the moon. So there can be
businesses that take advantage and that's and that's what we're trying to do.
Find businesses, motivate businesses that can then make a profit by flying
space missions.
Hari
Sreenivasan: You
know mining operations on the moon. I mean it seems so sci fi but who gets to
mine the Moon? I mean are we doing this as humanity, as one species so to speak
together or are we doing it as countries? Are we doing this as companies?
Mark Kirasich: Well we’ll have to develop the laws, the international laws and we'll
have to work those sorts of things out. Those are legal questions. I'm still
working on the engineering problems.
Hari Sreenivasan: Kirasich may be focusing on engineering
problems, but the fact is space exploration is no longer just a two person race
between the United States and the Soviet Union, as it was known in the ‘60s.
Space agencies in Europe, Japan, and India, have also sent probes to the moon.
Most recently, China landed a rover on the far side of the moon in January.
Fifty years ago in the
sprint to get to the moon, it was really just two runners. Now in this marathon
that is space exploration, you've got a lot more runners coming in. What does
that do to the race?
Mark Kirasich: You know not everybody is going the same place as the first thing
I'll tell you right. It really opens up the options for more runners to run
different races to use your analogy I have no doubt that there'll be some
competition involved and competition can be a healthy thing. The more
countries that want to go to the moon and out into the solar system the better.
We just need to ensure that deal at least not working against each other even
if we're not working together.
Hari
Sreenivasan: Are
you optimistic about that?
Mark Kirasich: I am.
I think we've got I think the hazards are so great and the cost of failure is
so high that folks are incentivized to work together.
Hari
Sreenivasan:
Despite the promise of more cooperation in space exploration, countries,
including the United States, still want to be first. and sending astronauts to
Mars is clearly the next big milestone. It’s a goal that President Trump made
explicit earlier this month.
President
Donald Trump: Someday
soon, we will plant the American flag on Mars.
Jeff Radigan: You want everybody looking up at the views of the spacecraft.
Hari
Sreenivasan: NASA
flight director Jeff Radigan says the agency is well
positioned to eventually send astronauts to the red planet.
Jeff Radigan: Where I see us in 20 years is taking that first trip to Mars where
I see us in 40 years is doing the same thing around Mars that we're doing
around the moon today which is having that permanent presence having those
folks there for a year or more and just continuing out into the solar system.
