Virgin Galactic pilots Mark “Forger” Stucky and Frederick “C.J.” Sturckow, who were awarded civilian astronaut wings last week, are among 18 pilots who have flown suborbital flights.
The two pilots flew SpaceShipTwo Unity to an altitude of 51.4 miles (82.72 km) on Dec. 13, 2018. That accomplishment qualified them for civilian astronaut wings using an American definition that places the boundary of space at 50 miles (80.46 km).
The National Defense Authorization Act passed by both houses of Congress calls for the construction of a memorial marker to the crew of Apollo 1 at Arlington National Cemetery. The measure awaits President Donald Trump’s signature.
The United States Army will lead the effort to create the memorial in consultation with NASA, the Commission of Fine Arts, and the Advisory Committee on Arlington National Cemetery.
Astronauts Virgil I. “Gus” Grissom, Edward White and Roger Chaffee were killed when a flash fire swept through their Apollo 1 command module during a practice countdown on Jan. 27, 1967. The astronauts had been scheduled to fly the first manned test of the spacecraft in Earth orbit the following month.
Grissom was one of the original seven Mercury astronauts who became the second American in space aboard Liberty Bell 7 and commanded Gemini 3, the first manned flight of that two-person spacecraft. White became the first American to walk in space during the Gemini 4 mission. Chaffee was scheduled to make his first spaceflight aboard Apollo 1.
The fire resulted in major overhaul of the troubled Apollo command module. The first manned flight of the Apollo program did not occur until October 1968, more than 20 months after the fire.
With Richard Branson once again predicting that Virgin Galactic will fly SpaeShipTwo into space before the end of the year, it seems like a good time to take a look at the history of suborbital spaceflight.
The number of manned suborbital flights varies depending upon the definition you use. The internationally recognized boundary is 100 km (62.1 miles), which is also known as the Karman line. The U.S. Air Force awarded astronaut wings to any pilot who exceeded 80.5 km (50 miles).
For nearly a dozen years, Virgin Galactic has used the number of individuals who have flown into space as a target to shoot for once the company began suborbital space tourism service. Virgin promised to double the number, which was around 500 when the company launched in 2004, within the first year of operation. That year was originally targeted for 2007 in the confident days after the success of SpaceShipOne.
That goal has long since faded away, and it’s unlikely Virgin will double the number of space travelers during the first year. In any event, the number of space travelers cited by Virgin has always been a bit misleading. The company’s well heeled customers, who are paying upwards of $250,000 per flight, will actually be joining a much more elite group on their suborbital flights.
