 Hey what's up everybody welcome to tomorrow and today we're going to be talking about how a dirty thruster has postponed the launch of the Jason 3 spacecraft and the Planetary Society thinks they've deployed a solar sail and NASA is about to test another flying saucer and that's what we're going to be talking about for this year's space pod for June 4th 2015. So first off the July 22nd launch of the Jason 3 spacecraft on a SpaceX Falcon 9 rocket has been postponed due to a contaminated thruster which has been removed and replaced. The National Oceanic and Atmospheric Administration will be conducting tests on the thruster over the next two weeks and the outcome of that review will determine the next launch date. Hopefully they'll be able to fix that and everything with the spacecraft will be okay and SpaceX's launch schedule won't have to be moved around too much. In SpaceX related news, back on May 29th Kevin Eichelberger found a payload fairing from a SpaceX rocket which mission is unclear but after Kevin tweeted about it and probably after some private conversations SpaceX will recover the fairing very soon from the Bahamas where it was found so that's pretty cool and what a luck you find. Meanwhile the Planetary Society launched a CubeSat called the light sail on the Atlas V rocket which recently launched the X-37B back into orbit. The light sail was just a secondary payload and after it was deployed the Planetary Society actually lost contact with the spacecraft for nine days. But after they were able to re-establish contact they proceeded with the mission and stabilized the spacecraft and from the data that they've been receiving they think that they have deployed the solar sail that is the primary mission of this light sail spacecraft. They haven't been able to take any pictures or video of it yet because there's not enough power in the spacecraft's batteries and once they're able to charge up to a certain point then they'll be able to activate their cameras and verify once and for all whether or not these solar sails have actually deployed. So good luck and congratulations to the Planetary Society for everything they've accomplished so far and hopefully this mission will be a success and the next light sail will be even more of a success. Finally NASA is launching a flying saucer although it's not anti-gravity. What it is is actually a low air density supersonic decelerator that will help to land heavier payloads onto the surface of Mars in the future. The way that it works is it'll be carried to a high altitude by a balloon after which it'll be dropped and four small rocket motors will fire up to spin stabilize the saucer. Two seconds later a solid rocket motor will ignite and thrust the vehicle to the edge of the stratosphere. After the solid rocket motor burns out four additional small rocket motors will fire up to despin the saucer. Its max speed will be about Mach 4 and once it decelerates to Mach 3 the vehicle will deploy the supersonic inflatable aerodynamic decelerator. The inflatable decelerator will slow the vehicle down even further to around Mach 2.4 and then a parachute will deploy that will slow the vehicle down until it is able to have a nice soft splash down in the ocean. The goal of this decelerator is to eventually be able to land heavier payloads onto the surface of Mars. Since Mars' atmosphere is a lot less dense than the Earth's atmosphere it's really hard to just use parachutes to be able to decelerate and land safely on the surface somewhere. The most recent rover to Mars curiosity was one metric ton and the way they were able to safely land on Mars was with a very risky but thankfully successful sky crane. The sky crane, as ingenious as it is, is just not effective enough to get heavier payloads onto the surface of Mars safely. So NASA is hoping that with this new decelerator they'll be able to get somewhere around three metric tons of payload onto the surface of Mars, and that would be able to open up a whole lot of possibilities. Whether permitting they're hoping to launch this flying saucer later today, I've included links below to where you can watch that live on NASA television and their U-Stream. Hopefully everything will go well with this whole flying saucer decelerator test as well as the Planetary Society's light sail test and hopefully they'll get things working with the Jason 3 spacecraft very soon as well.
