Mark Sirangelo, who heads Sierra Nevada’s Space unit, was the very first President of ReproCAD (way back before ReproCAD and MiniMAX merged to form ReproMAX).
After his stint with ReproCAD, Mark, in 1986, joined John Scher Zeller, Rich Heller and Joel Salus on Rowley-Scher Reprographics’ management team. Mark’s final position with Rowley-Scher was President. After leaving Rowley-Scher (around 1990), Mark went on to found PGI, a U.S.-based international meetings, convention and event planning company. All of that was before Mark got involved in the “space industry.”
While reprographics isn’t “rocket science”, it must have served as a good foundation for rocket science!
Best wishes to Mark on his company’s pursuit of the NASA contract.

"Space plane flies but has a rough
landing in test run"
(Space plane)…..that could one day carry astronauts had
a rough landing in its other wise smooth first test run. For the would-be
spaceship named the Dream Chaser, everything on the first flight of a prototype
went-perfectly — until the craft touched down, toppled on its side, skidded off
the runway and wound up in the sand of the Mojave Desert.
The unmanned test flight, conducted in hushed conditions
Saturday at Edwards Air Force Base in Southern California, came to an inelegant
end after the left landing gear failed to deploy properly.
But the creator of the space plane, Sierra Nevada Corp.,
which is hoping to win a NASA contract to carry astronauts to the international
space station, found much to celebrate despite the rough landing. The vehicle,
dropped by a helicopter at 12,500 feet, flew autonomously in a steep dive,
pulled up perfectly and glided to the center line of the runway, the whole
flight precisely by the book until the very end, Mark Sirangelo, head of Sierra Nevada’s space
unit, said in a teleconference Tuesday.
“We had a very successful day with an unfortunate
anomaly at the end of the day on one of the landing gears,” Sirangelo said.
Putting an even more positive spin on the floppy landing, he said, “Even the
final ending, which did not roll out perfectly, provided some very valuable
data for us as well.”
Sierra Nevada has put out a video showing the flight,
but the video cuts off just as the Dream Chaser is landing. Sirangelo said the
company is unlikely to produce additional footage while the “anomaly” is being
investigated.
Sierra Nevada is perhaps the underdog in the competition
to win the NASA contract to haul astronauts to the international space station.
The company spent the good part of a decade developing the Dream Chaser, which
looks like a miniature space shuttle. It would be launched atop an Atlas 5
rocket. Like the shuttle, it is designed to glide back to Earth and land on a
runway. It has not yet flown in space; the first such mission, unmanned, will
probably take place in 2016, Sirangelo said.
NASA’s “commercial crew” program has offered subsidies
to Sierra Nevada along the way. According to NASA, Sierra Nevada had received
$229.1 million in payments from NASA through the end of September under a
series of agreements and contracts.
Among the companies that have also received commercial
crew subsidies are SpaceX and Boeing. SpaceX, founded by tycoon Elon Musk, is
taking cargo to the space station and hopes to add astronauts to its manifest
in the near future, and Musk is vocal about his desire to send people to Mars.
Boeing is an aerospace giant for which human spaceflight is essentially a side
business.
Sierra Nevada, however, is more narrowly focused.
“We’re not trying to land on the moon or Mars,”
Sirangelo said earlier this year. “That’s not our mission. Our mission is to
take over low Earth orbit so that NASA can go on and do something else.”
Next year, NASA is expected to do a “down-select” in its
commercial crew program and will presumably pick two companies to move forward.
Officials have said they do not want to rely on a single provider. Congress in
recent years has not funded the commercial crew program at the level requested
by the administration. The goal is to have commercial rides to space by 2017,
although NASA officials have said that could slip without full funding of the
program.
The space shuttle was retired in 2011. Currently, the
only way U.S. astronauts can reach the space station, or return to Earth, is
via Russian rockets.
SpaceX and Boeing are developing crew capsules that
would reenter the atmosphere the way Apollo capsules did nearly half a century
ago, with the final descent slowed by parachutes. SpaceX would launch its
capsule atop the company’s own rocket, the Falcon 9, while Boeing’s capsule
would, like the Dream Chaser, ride atop an Atlas 5, the rocket owned by United
Launch Alliance, a 50-50 joint venture of Boeing and Lockheed Martin.
