Virgin Galactic: We Don’t Anticipate Motion Sickness

When the spaceship Enterprise — Virgin Galactic’s SpaceShipTwo, not the Star Trek spacecraft — fired its rocket engines for the first time in flight last week, it set off a new frenzy of talk about tourists flying in space.

More than 500 people have made their $200,000 reservations; the price is actually going up to $250,000 in the near future, according to media reports, to adjust for inflation.

Among those hundreds of people, it’s possible that a few could be susceptible to motion sickness.

In space, particularly when you’re floating around freely, it’s hard for your body to tell up from down. This can happen even if you’re sitting still; one astronaut once told NASA how freaked out his body was when he woke up in the morning, expecting to be lying on the right as usual. He was in that position, but staring at the ceiling.

When SpaceShipTwo goes to space, it will make one big parabola — soaring arc — before returning to Earth. It’s a similar trajectory to one cycle flown by the “Vomit Comet”, an infamous program run by NASA to do experiments and research on an airplane in temporarily weightless conditions. The aircraft dives up and down a few dozen times in a typical run, and the environment flips from microgravity to a pull that is much stronger than usual. This can create some heaving stomachs.

But let’s put space adaptation syndrome into perspective. Senator Jake Garn, when he flew on shuttle Discovery in 1985, famously became quite ill for reasons often attributed to motion sickness. After his return, there were those within NASA that began measuring the amount of space sickness in “Garns”, according to NASA physician Robert Stevenson in a 1999 interview with NASA. By that scale, illness problems are generally pretty mild.

Jake Garn, he has made a mark in the astronaut corps because he represents the maximum level of space sickness that anyone can ever attain, and so the mark of being totally sick and totally incompetent is one Garn. Most guys will get maybe to a tenth Garn, if that high. And within the astronaut corps, he forever will be remembered by that.

According to Virgin, though, they anticipate practically no Garns at all. Here’s what Virgin spokesperson Jessica Ballard (who is with Griffin Communications Group) told Universe Today:

Virtually no customers on board parabolic aircraft experience any motion effects on the first parabola. Since our experience could be thought of as one large single parabola, we expect very low incidence of any motion effects. In addition, our experience will also have significantly slower transitions between zero-g and positive G than parabolic flight, which we expect to improve our customers’ experience.

Thus, we anticipate that most of our passengers will not require motion sickness medication. The decision to use prophylactic [preventative] medication, and which form of medication should be used, will be made on a case by case basis with each passenger. Because of this, we’re confident that our customers will be both ready and eager to get up out of their seats once they reach space.

How susceptible are you to motion sickness, and does it occur for you in flight? Let us know in the comments.

Watch SpaceShipTwo’s First Feathered Flight

On May 4, 2011 Virgin Galactic’s SpaceShipTwo achieved a major milestone by flying for the first time using its “feathered” configuration, and the company has now released a close-up video of the flight. Feathering is designed to create drag and slow the ship down after it reenters the atmosphere from eventual suborbital flights taking tourists into space. This flight confirmed the feathering design should work.

“Now we now have an entry vehicle – now we can come back from space,” said Matt Stiemetze, Program Manager at Scaled Composites

Virgin Galactic’s SpaceShipTwo achieved a major milestone early Wednesday 4th May 2011, as it successfully demonstrated its unique reentry ‘feather’ configuration for the first time. This test flight, the third in less than two weeks, brings powered test flights and — ultimately — commercial operations a step closer.

SpaceShipTwo (SS2), named VSS Enterprise, went airborne attached to WhiteKnightTwo (WK2) carrier aircraft, VMS Eve at 6:43AM PDT at the Mojave Air and Spaceport in California. After a 45 minute climb to 51,500 feet, SS2 was released from VMS Eve and established a stable glide profile before deploying, for the first time, its re-entry or “feathered” configuration by rotating the tail section of the vehicle upwards to a 65 degree angle to the fuselage. It remained in this configuration with the vehicle’s body at a level pitch for approximately 1 minute and 15 seconds while descending, almost vertically, at around 15,500 feet per minute, slowed by the powerful shuttlecock-like drag created by the raised tail section. At around 33,500 feet the pilots reconfigured the spaceship to its normal glide mode and executed a smooth runway touchdown, approximately 11 minutes and 5 seconds after its release from VMS Eve.

Virgin Galactic says all objectives for the flight were met and detailed flight data is now being analyzed by the engineers at Scaled Composites, designers and builders of Virgin Galactic’s sub-orbital spacecraft.

“This morning’s spectacular flight by VSS Enterprise was its third in 12 days, reinforcing the fast turnaround and frequent flight-rate potential of Virgin Galactic’s new vehicles,” said George Whitesides, CEO and President of Virgin Galactic. “ We have also shown this morning that the unique feathering re-entry mechanism, probably the single most important safety innovation within the whole system, works perfectly. This is yet another important milestone successfully passed for Virgin Galactic, and brings us ever closer to the start of commercial operations. Credit is due to the whole Scaled team, whose meticulous planning and great skill are changing the course of history.”

“In all test flight programs, after the training, planning and rehearsing, there comes the moment when you have to go up there and fly it for real,” said Pete Siebold, who along with Clint Nichols piloted SS2. “This morning’s flight was a test pilot’s dream. The spaceship is a joy to fly and the feathered descent portion added a new, unusual but wonderful dynamic to the ride. The fact that it all went to plan, that there were no surprises and that we brought VSS Enterprise back to Mojave safe and sound is a great testament to the whole team.”

Does this image look futuristic? Well, the future is here, as this is an actual image from October 10, 2010 (today!) Virgin Galactic’s future passenger ship made its first manned glide flight on Sunday. SpaceShipTwo’s unpowered flighted lasted about 11 minutes after the spacecraft was released from its White Knight Two mother ship, Eve, at 13,700 meters (45,000 feet) over the Mojave Desert. Scaled Composites test pilot Pete Siebold flew her down to the Mojave Spaceport, with with Mike Alsbury as co-pilot. “The VSS Enterprise was a real joy to fly,” said Siebold after landing, “especially when one considers the fact that the vehicle has been designed not only to be a Mach 3.5 spaceship capable of going into space but also one of the worlds highest altitude gliders.”

UPDATE: Virgin has now released a video of the flight, see below.

SpaceShipTwo will carry six people in addition to two pilots, providing those on board with a view of space and several minutes of weightlessness once space flights begin. Eventual operational flights of SpaceShipTwo will occur from Spaceport America in New Mexico. Latest word is that the first passenger flights could begin in 2011.

All the flight and all systems appeared to operate trouble free. After a clean release, Siebold completed initial flight handling and stall characteristic evaluation of SpaceShipTwo. After completing a practice approach and landing, Siebold made a smooth landing.

“This was one of the most exciting days in the whole history of Virgin,” said Richard Branson, founder of Virgin Galactic. “For the first time since we seriously began the project in 2004, I watched the world’s first manned commercial spaceship landing on the runway at Mojave Air and Space Port and it was a great moment. Now, the sky is no longer the limit and we will begin the process of pushing beyond to the final frontier of space itself over the next year.”

“This is a critical milestone in Virgin Galactic’s test program and a great day for the commercial spaceflight industry,” added John Gedmark, Executive Director of the Commercial Spaceflight Federation. “At the end of the day, getting hardware off the ground is what it’s really all about. Today’s SpaceShipTwo test flight marks another key milestone towards opening the space frontier for private individuals, researchers, and explorers. Congratulations to the entire SpaceShipTwo team.”

SpaceShipTwo and WhiteKnightTwo are being developed for Virgin Galactic by Scaled Composites, who built SpaceShipOne, the first privately-built vehicle to fly a person into space, which won the $10 million Ansari X PRIZE.

Future passengers will be flown about 100km (62 miles) above the Earth and experience several minutes of weightlessness before returning to Spaceport America. Tickets cost $200,000 and deposits start from $20,000. Find more info about passenger flights at Virgin Galactic’s website

Virgin’s Spaceship Enterprise Makes First Crewed Flight

For the first time, Virgin Galactic’s SpaceShipTwo, named the Enterprise, flew with crew on board. While it stayed attached to the “Eve” mothership for the duration of the July 15 flight, Scaled Composites – the builders of the spacecraft – called the flight a “significant milestone as the team marches towards the first solo flights.” Numerous combined vehicle systems tests were conducted, as two crew members on board VSS Enterprise evaluated all of the spaceship’s systems and functions from end to end in the air, and all objectives were achieved.

This was the third time the Enterprise had flown in its “captive carry” configuration, but the first time with crew on board. It was the 33rd flight for WhiteKnightTwo, also known as Eve. The flight time was 6 hours 12 minutes.

The crew on the Enterprise was Peter Siebold, Michael Alsbury, and on board Eve were Mark Stucky, Peter Kalogiannis, and Brian Maisler.

SpaceShipTwo can fly up to eight people (six passengers and two pilots) on suborbital flights that would provide a weightless experience for 4-6 minutes. Will Whitehorn, president of Virgin Galactic, has stated that the company would “not put a definite timeline on when the commercial flights would begin” but if all goes according to plan they hope to make their first passenger flights in 2011. Tickets are on sale for $200,000 per person.

First Flight of Virgin Galactic’s SpaceShipTwo

Virgin Galactic, the private aerospace company founded by billionaire Richard Branson, successfully tested the passenger space-plane SpaceShipTwo today. SpaceShipTwo (SS2), is also called the Virgin Space Ship Enterprise, or VSS Enterprise, an obvious tribute to another space vehicle of some note. SS2 was carried to 45,000 feet (13.7km) by its mothership, named WhiteKnightTwo (WK2), or ‘Eve’, after Branson’s mother. In this initial ‘captive carry’ test of the space plane, it remained attached to the mothership for the duration of the flight.

The SS2/WK2 combo took off from a runway at the Mojave Air and Space Port in California, and flew for approximately three hours over the deserts of the Antelope Valley. SS2 is a prototype passenger vehicle that is designed to take astronauts to suborbital flight. If the remaining tests go as planned, it will eventually take a crew of two pilots and up to six passengers to the edge of space, at just over 100km (62 miles).This may happen as early as the end of 2011.

SpaceShipTwo is an all-carbon composite plane that uses a hybrid rocket motor, and will be carried to 50,000 feet (15.2 km) by WhiteKnightTwo before being released. It will then fire the rocket to propel it above the Karman line.

Here’s a video of the takeoff and landing of SS2 today:

SS2 was unveiled to the public in December of last year, and this is the first in a series of tests to determine how safe and operational the craft is before it can begin to bring passengers into space. It will undergo another captive carry flight to 50,000 feet, and then will be brought into the air by WK2 and released in subsequent tests.

SpaceShipTwo was designed by Burt Rutan of Scaled Composites, who also led the design team for SpaceShipOne, which won the Ansari X-Prize of $10 million in 2004 for completing the first series of manned commercial spaceflights.

If you have $200,000 laying around and want to go into space, SS2 is your space plane. However, you’re going to have to get in line: over 300 people have already signed up for seats on the plane.

First Look at SpaceShipTwo

Virgin Galactic will unveil SpaceShipTwo (SS2), Monday night, but they did sneak out a few photos prior to the event. SS2 will be the world’s first commercial manned spaceship, with room for several passengers to move (and fly!) around during suborbital flights. “This is truly a momentous day. The team has created not only a world first but also a work of art,” said Sir Richard Branson, Virgin Galactic founder. Burt Rutan, the designer of SpaceShipOne which won the Ansari X PRIZE in 2004 for completing the world’s first manned private space flights said, “All of us at Scaled Composites are tremendously excited by the capabilities of both the mothership and SS2.”

A “theatrical unveil” Monday night at the Mojave Spaceport will be followed by a cocktail party for the 300 plus paying passengers that have already signed up for flights on SS2, along with other VIPs of the space industry.

SpaceShipTwo’s debut marks the first public appearance of a commercial passenger spacecraft. SS2 has been under construction for two years. On board, there will be room for six passengers and two pilots.

Daily space tourism flights for SS2 are set to begin in New Mexico from Spaceport America following the completion of test programming and US government licensing. SS2 will be carried by WhiteKnightTwo mothership, a four-engine jet-powered aircraft unveiled last year that features twin fuselages mounted on either side of a huge wing. SS2 will be mounted in the center.

SpaceShipTwo will be released at an altitude of 15,240 meters (50,000 feet.) A hybrid rocket motor burning solid propellant with nitrous oxide then will boost SpaceShipTwo onto a steep trajectory to an altitude of more than 100 km (62 miles.)

Here’s an image comparing SS2 with SpaceShipOne:

The first SpaceShipTwo test flights are expected to start next year, with full-fledged space launches to its maximum altitude by or in 2011.

The 300 paid passengers have already put down the $200,000 ticket or placed a deposit, according to the company.

Branson Wants to Fly Space Tourists into the Northern Lights

aurora_iss.thumbnail.jpg

For his next big plan for the private space industry, Richard Branson is thinking up new ways to excite affluent space tourists: flying them into the biggest lightshow on Earth, the Aurora Borealis. Although the New Mexico Virgin Galactic Spaceport isn’t scheduled for completion until 2010, the British entrepreneur is already planning his next project intended for cruises into the spectacular space phenomenon from an Arctic launchpad.

Located in the far north of Sweden (in the Lapland province), the small town of Kiruna has a long history of space observation and rocket launches. The Arctic location provides the town with unrivalled views of the Aurora Borealis as it erupts overhead. The Auroral lightshow is generated by atmospheric reactions to impacting solar wind particles as they channel along the Earth’s magnetic field and down into the thickening atmospheric gases.

Once a view exclusive only to sounding rockets, this awe inspiring sight may in the future be seen from the inside, and above, by fee-paying space tourists as they are launched into space from a new spaceport, on the site of an existing base called Esrange. Although launching humans into an active aurora holds little scientific interest (if it did, it would have probably been done by now), it does pose some prudent health and safety questions. As Dr Olle Norberg, Esrange’s director, confidently states: “Is there a build-up of charge on the spacecraft? What is the radiation dose that you would receive? Those studies came out saying it is safe to do this.” Phew, that’s a relief.

The chance to actually be inside this magnificent display of light will be an incredible selling point for Virgin Galactic and their SpaceShipTwo flights. As if going into space were not enough, you can see and fly through the atmosphere at it’s most magnificent too.
