There’s a lot on SpaceX’s agenda this year if the company can maintain its
pace, including refinements of the Falcon 9 rocket to hasten refurbishment
between flights and the debut of the long-delayed Falcon Heavy launch
vehicle with two side boosters recycled from previous missions, according
to company founder Elon Musk.

The Falcon Heavy’s maiden flight is expected in late summer, Musk said
Thursday after the launch of SpaceX’s first reused Falcon 9 rocket booster.
It will be a “high-risk” mission, he said, and SpaceX plans to launch it on
a pure demonstration flight.

Musk unveiled plans for the Falcon Heavy rocket in April 2011 in a press
conference at the National Press Club in Washington. SpaceX said then that
the triple-body rocket, powered by three rocket stages derived from the
Falcon 9, would fly beginning in 2013.

SpaceX starting signing customers for Falcon Heavy missions in 2012, and
the development delays forced at least two clients — Inmarsat and ViaSat —
to switch their satellites to the rival Ariane 5 rocket, while retaining
bookings for future launches.

“Falcon Heavy is one of those things that. at first, sounded easy,” Musk
said Thursday. “We’ll just take two first stages and use them as strap-on
boosters. Actually, no, this is crazy hard, and it required the redesign of
the center core and a ton of different hardware.

“It was actually shockingly difficult to go from a single-core to a
triple-core vehicle,” Musk said.

SpaceX says the Falcon Heavy is a secondary priority behind maintaining the
launch tempo for the smaller Falcon 9. Officials blamed some of the Falcon
Heavy delays on Falcon 9 failures in June 2015 and September 2016 that
grounded the SpaceX rocket fleet several months each time.

Musk said SpaceX has around 20 more missions on its manifest this year, and
only two will likely be with the Falcon Heavy, assuming it debuts by late
summer.

Musk said major testing of the Falcon Heavy is complete, and engineers are
now finishing fabrication of flight hardware.

“I think they finish in about two or three months,” he said.

The inaugural Falcon Heavy will lift off from launch pad 39A at NASA’s
Kennedy Space Center in Florida, a facility first built for the Apollo
program’s Saturn 5 moon rocket, then modified for space shuttle missions.
SpaceX leased the pad from NASA in 2014, and rushed its upgrades to
completion after a Falcon 9 rocket exploded on nearby pad 40 in September,
leaving that launch complex with significant damage.

SpaceX will need several months to repair pad 40, then the company will
relocate Falcon 9 launch operations there to fully outfit pad 39A for the
Falcon Heavy. Managers also want to have pad 40 available in case a Falcon
Heavy damages pad 39A, Musk said.

“Falcon Heavy, I really want to emphasize, that’s a high-risk flight — 27
engines are lighting simultaneously,” Musk said. “That’s a lot of engines.

“Technically, it should have been called the Falcon 27,” he joked. “Maybe
that sounded too scary, so we called it the Falcon Heavy.”

SpaceX has not disclosed the orbital destination targeted on the first
Falcon Heavy mission, but Musk said the company will likely fly “the
silliest thing we can imagine” on the maiden flight.

SpaceX placed a wheel of cheese inside the Dragon spacecraft on its first
orbital flight in an ode to the Monty Python comedy group.

“That will be exciting mission, one way or another,” Musk said. “Hopefully
in a good direction.”

The two reused side boosters will detach from the central core a few
minutes into the flight and return to Cape Canaveral for landing. The core
booster will continue downrange and land on SpaceX’s ocean-going platform
in the Atlantic.

“The two side boosters will come back and do sort of a synchronized aerial
ballet and land,” Musk said. “Two of the side boosters will land back the
Cape. That’ll be pretty exciting to see two come in simultaneously, and the
center core will land downrange on the drone ship.”

SpaceX may try to recover the second stage on the first Falcon Heavy flight
in a maneuver never before attempted. The upper stage, which enters orbit
at a velocity of more than five miles per second would need a beefier heat
shield than the first stage, which comes down at lower speeds.

“Considering trying to bring upper stage back on Falcon Heavy demo flight
for full reusability,” Musk tweeted. “Odds of success low, but maybe worth
a shot.”

If the first Falcon Heavy flight goes well, the U.S. Air Force has booked
the second launch to haul up multiple research satellites for the military,
NASA and universities. The Space Test Program-2, or STP-2 flight will place
the payloads in multiple orbits at different altitudes.

Thursday’s reflight of a previously-used Falcon 9 first stage booster went
a long way toward SpaceX’s goal of recovering and rapidly relaunching
rockets, an achievement Musk said could, theoretically, reduce launch costs
by a factor of 100.

“The design intent is that the rocket can be reflown with zero hardware
changes,” Musk said. “In other words, the only thing you change is you
reload the propellant.”

SpaceX’s goal is to launch each Falcon 9 first stage 10 times with only
inspections.

“Then, with moderate refurbishment that doesn’t have a significant effect
on the cost, it can be reflown at least 100 times,” Musk said.

He said SpaceX’s engineers were “incredibly paranoid” preparing the
previously-flown rocket for launch last week with the SES 10 communications
satellite. The booster first flew in April 2016 carrying a Dragon supply
ship toward the International Space Station, then landed on SpaceX’s
offshore platform.

The rocket repeated that feat Thursday, again returning to Earth on
SpaceX’s drone ship.

“The core airframe remained the same,” Musk said. “The engines remained the
same, but any auxiliary components that we thought might be slightly
questionable, we changed out.”

SpaceX plans up to six more reflights of Falcon 9 first stage boosters this
year, including the two side boosters on the first Falcon Heavy. Officials
have not identified customers for the other reuse launches, but SES chief
technology officer Martin Halliwell told reporters that the SES 14 and SES
16 communications satellites scheduled to launch on Falcon 9 rockets in the
fall are candidates to ride on a previously-flown launch vehicle.

The company recently leased a disused former Spacehab processing facility
near the southern gate of Cape Canaveral Air Force Station to refurbish
rocket hardware. SpaceX has retrieved eight first stage boosters to date —
including landing one vehicle twice — but at least three of those first
stages are not intended to fly again.

The first booster that landed at Cape Canaveral in December 2015 is on
display outside SpaceX’s headquarters building in Hawthorne, California,
and the first stage that launched last week with SES 10 will be put on
public display somewhere at the Florida spaceport. Engineers ran through a
series of extensive ground testing with a rocket that lifted off with a
Japanese communications satellite last year, leaving it unsuitable for a
second launch.

Another upgrade to the Falcon 9 family is due later this year to ease the
work needed between flights of the same first stage booster, raise the
power of the rocket’s Merlin engines, and test out safety features for
future launches with astronauts.

The so-called Block 5 configuration of the Falcon 9 will fly at least seven
times with a “frozen” design before NASA puts astronauts on the rocket,
according to space agency officials.

SpaceX is one of two companies — along with Boeing — working on commercial
spaceships to ferry crews to and from the space station. The Crew Dragon
capsule will launch on Falcon 9 rockets from pad 39A, and SpaceX has
finished construction of a new access arm for astronauts to board the
spacecraft before liftoff.

The access arm will be installed at pad 39A some time later this year
during a lull in launch operations.

A test flight of the Crew Dragon spaceship without astronauts aboard is
penciled in on SpaceX’s manifest for November, followed by a demonstration
with two crew members no sooner than May 2018.

NASA considers those target launch dates optimistic, and they assume
everything goes according to plan, said Kathy Lueders, manager of NASA’s
commercial crew program, in a presentation last week to the NASA Advisory
Council’s Human Exploration and Operations Committee.

“The most important part of Block 5 will be operating the engines at their
full thrust capability, which is about 7 or 8 percent — almost 10 percent —
more than what they currently run at,” Musk said. “And a number of other
important (things) to have reusability go smoothly as well, like the forged
titanium grid fins. It’ll bring in a bunch of other factors.”

the booster’s re-entry March 30 after launching the SES 10 communications
satellite. Credit: SpaceX

The new grid fins will replace the first stage’s current aluminum winglets,
four of which help stabilize and steer the rocket during descent. SpaceX
added the grid fins to the first stage after crashing for the first attempt
to land a rocket on the drone ship, incorporating the deployable fins to
improve steering.

On a typical launch, the first stage jettisons from the upper segment of
the Falcon 9 around two-and-a-half minutes after liftoff, then activates
cold gas nitrogen thrusters to to flip around to fly tail first. Soaring
above 60 miles (100 kilometers) in altitude, the internationally recognized
boundary of space, a subset of the booster’s nine Merlin engines then
reignite multiple times to slow down for a vertical landing.

“Some of the technical elements that are the most tricky, I think, for
reuse are the base heat shield of the rocket (and) the grid fins,” Musk
said. “If you saw the webcast (of SES 10’s launch), you may have noticed
the grid fins were lighting on fire.”

The aluminum grid fins currently flying on the Falcon 9 are covered in heat
shield material.

“But it gets so hot that it lights on fire a little bit, which is not great
for reuse,” Musk said. “The new grid fins should be capable of taking a
scorching and being fine.”

The upgraded rocket will have more control authority on descent, Musk added.

“It will actually improve the payload to orbit by being able to fly at a
higher angle of attack, and use the aerodynamic elements to effectively
glide,” Musk said. “It actually does have a lift-over-drag (ratio) of
roughly one if flown at the right angle of attack, but you need control
authority, particularly pitch control authority.”

Engineers want to add a thermal barrier coating to replace the paint
currently used on the first stage, which can melt and bubble from the
extreme heating of re-entry.

The heat shield at the base of the rocket protects the engines and the
plumbing of the booster’s propulsion system. It currently has to be
replaced between each launch of the same rocket.

“I think we’ve got the base heat shield thing addressed,” Musk said. “We’ve
got a good plan for the grid fins, and there are a bunch of little things
that need to be ironed out.”

But Musk said he is optimistic SpaceX can achieve his goal of landing and
reflying a first stage booster within 24 hours as soon as next year.

“It does seem as though we may do maybe half a dozen more flights of a
reflown booster this year, and then next year probably double that,” Musk
said. “Then I would suspect that, for the Falcon architecture over time,
probably three-quarters of our missions, or more, are with a reflown
booster.”

Engineers also are experimenting with recovering the Falcon 9 payload
fairing, a composite structure that covers satellites during the first few
minutes of launch, then splits open in two halves to fall into the sea.

Musk confirmed one half of the fairing from the SES 10 launch Thursday
landed intact, using tiny thrusters and a steerable parachute to soften its
splashdown in the Atlantic Ocean.

The Block 5 upgrade — Musk said he prefers to call it Version 2.5 — will
include around 100 changes to the vehicle, according to Gwynne Shotwell,
SpaceX’s president and chief operating officer.

Shotwell said in February that the changes include a fix to a turbine wheel
cracking issue in the Falcon 9’s Merlin engines publicly disclosed in a
government watchdog report.

Musk’s long-term objective for SpaceX is to dispatch huge transport ships
to Mars, eventually carrying hundreds or thousands of people to settle on
the red planet.

Rocket reusability “is a critical part of the Mars plan, if you consider
the goal … is not to be a single mission, but one where we establish a
self-sustaining city on Mars,” Musk said.
