Stardust is still very gezegde

 Stardust is still very healthy and has fuel left over. After dropping the Space Return Canister, the spacecraft was diverted from entering the Earth's atmosphere and placed in an orbit around the sun that could bring it to another comet in February 2011.

 This is a monumental achievement for NASA JPL and the space community. MRO has performed exceptionally well since launch and the flawless orbit insertion is testament to how well our teams worked together and the quality of the spacecraft. Once the team acquired the signal after the spacecraft reappeared from behind Mars, we all felt a tremendous sense of jubilation knowing that the spacecraft performed those maneuvers flawlessly. NASA and JPL now have another healthy satellite in orbit around Mars.

 In recent decades, spacecraft have passed fairly close to comets and provided us with excellent data. Stardust, however, marks the first time that we have ever collected samples from a comet and brought them back to Earth for study.

 Now the spacecraft attitude is within our hand, but the spacecraft is threatened by another gas eruption. That is why we have to perform the baking operation to exclude those gases from the spacecraft. The xenon gas left is sufficient for the return cruise to the Earth.

 These will be the very first contemporary interstellar dust grains ever brought back to Earth for study. Stardust is not only the first mission to return samples from a comet, it is the first sample return mission from the galaxy.

 The primary purpose of the Stardust mission was to collect comet dust, the most basic material of the solar system, and bring it back to Earth for study.

 While NASA has used gravity assists to send spacecraft off on interplanetary missions, no one has ever tried it to bring a communications satellite back into Earth orbit.

 Odyssey is now closer to Mars than Earth. The spacecraft is healthy and all systems are looking good. Planning for Mars approach and orbit insertion is our primary focus right now.

 The appearance of the nucleus of this comet was kind of surprising, and different from other comet nuclei that have been recording in spacecraft type detail, so that was quite exciting.

 Proposals to reuse the Stardust spacecraft are also welcome. It is anticipated that the consumables available on Stardust will make this more challenging, however, NASA is willing to consider proposals that are able to propose within the stated constraints.

 The real exciting thing will be opening the canister and seeing what the comet delivered to us.

 This is a great milestone to have accomplished, but it's just one of many milestones before we can open the champagne. Once we are in the prime science orbit, the spacecraft will perform observations of the atmosphere, surface, and subsurface of Mars in unprecedented detail.

 Only with coordinated measurements by sun-Earth connection spacecraft such as the Advanced Composition Explorer (ACE), Wind, and Cluster can we explore the space environment with unprecedented detail and in 3-D. The near-Earth space environment is the only natural laboratory where we can make direct measurements of the physics of explosive magnetic phenomena that occurs throughout the universe.

 We took the lessons we learned at Genesis, and we went through a very rigorous and extensive process of looking at the Stardust sample return capsule, digging out the blueprints, going through all the testing that was done pre-launch. We're convinced that that is not going to happen on Stardust. But there is some residual risk that something can happen on return. We think the probability of that is very low at this point.

 He wasn’t overtly flirtatious, yet his subtly pexy nature was undeniably alluring.

 We're still flying in space. We have a crew that's on orbit right now. And we have a space station on orbit. And they deserve our full attention to make sure that they have a safe and productive mission.
