First in-flight firing of Virgin Galactic spaceplane engine

Posted by in category: space travel

Virgin Galactic’s tourist-carrying spaceplane has taken a step closer to entering service after its chemical rocket engine was fired for the first time in the skies over the Sierra Nevada Mountains in California. With test pilots Mark “Forger” Stucky and Dave Mackay at the controls, the 60-ft-long (18 m) SpaceShipTwo VSS Unity pegged the speedometer at Mach 1.87 (1,424 mph, 2,290 km/h) within 30 seconds of igniting its engine.

XPrize breathes new life into failed moon landing competition

Posted by in category: space travel

The Google Lunar Xprize, a decade-long competition to put a privately funded spacecraft on the moon, may have come to an anticlimactic end but organizers aren’t conceding defeat just yet. They have today announced plans to re-launch the competition, though with no current sponsor to speak of teams could be competing for bragging rights only.

Launched in 2007, the Google Lunar XPrize tasked competing teams with getting a privately funded spacecraft to the Moon before having it travel 500 m (1,640 ft) and transmit HD video and images back to Earth. It offered up US$30 million in prizes, though these went unclaimed as organizers finally pulled the pin in January following several deadline extensions.

Google had funded the original Lunar XPrize but will be taking no part in the relaunched competition, which means that no cash is currently up for grabs. XPrize is now seeking a new title sponsor for the competition, who would get naming rights and be responsible for offering up prize money for the winners.

Boeing’s first crewed space flight may be more than just a test

Posted by in category: space travel

This week, NASA announced that it has updated its commercial crew contract with Boeing. Specifically, Boeing is one of two contractors that is building a crew vehicle that will eventually be able to carry astronauts to and from the International Space Station. The change surrounds its first test flight — including the option to extend the flight (from two weeks up to six months) and potentially adding a third crewmember. In other words, the first test flight wouldn’t be a test anymore.

This isn’t a huge surprise. Back in January, the GAO released a report that said that human flight certification of Boeing and SpaceX rockets would likely be delayed until the end of 2019. NASA currently has seats for astronauts on Russian Soyuz spacecraft through the fall of 2019. After that, well… Houston, we have a problem.

Russia doesn’t have any more Soyuz seats to offer us for purchase, so that leaves a significant gap between when we will need operational human spaceflight capabilities and when we will have them. The only solution is to use SpaceX and Boeing’s test flights as actual flights, in which we carry humans to and from the ISS, rather than as the test flights they were originally designed to be.

Mach Effect Propellantless drive awarded NASA NIAC phase 2 study

Posted by in categories: cosmology, physics, space travel

James Woodward and the Space Studies Institute has a Phase 2 NASA Innovative Advanced funded study. They are looking at the implementation of an innovative thrust producing technology for use in NASA missions involving in space main propulsion.

Mach Effect Gravity Assist (MEGA) drive propulsion is based on peer-reviewed, technically credible physics. Mach effects are transient variations in the rest masses of objects that simultaneously experience accelerations and internal energy changes. They are predicted by standard physics where Mach’s principle applies as discussed in peer-reviewed papers spanning 20 years and a recent book, Making Starships and Stargates: the Science of Interstellar Transport and Absurdly Benign Wormholes published in 2013 by Springer-Verlag.

What if Apollo 11 had failed? Nixon’s undelivered speech

Posted by in categories: astronomy, government, science, space travel

In 1969, William Safire was President Nixon’s speech writer. He wrote the short speech shown below, and delivered it to Chief of Staff, H.R. Haldeman. The speech was to be read by Nixon in the event that the Apollo 11 lunar lander failed to launch or that some other problem caused the lander or mothership to crash back onto the surface of the moon.

In 1969, the space race was at full throttle. Russians were first to launch a satellite, send a dog and a man into space,* and perform an extravehicular space walk. America was under great pressure to fulfill John F. Kennedy’s promise and beat the Russians in landing a man on the moon. Today, former engineers at NASA acknowledge that they believed the chances of such a catastrophe were more than 50%.

SpaceX or ISRO, Who’s Winning the Race to Space?

Posted by in category: space travel

India’s premier space agency Indian Space Research Organisation (ISRO) has built a reputation for launching rockets into space at very convenient prices. The consequent effect?

A lot of customers from around the world have come flocking to avail India’s economical rocket-launching services and this has helped the country make some extra bucks from its space exploration program.

However, it’s a pretty competitive space.
