Nasa Parker Solar Probe will be the first time a human-made object comes so close to the sun: just six million kilometers away. https://www.nasa.gov/feature/goddard/2018/nasa-prepares-to-launch-parker-solar-probe-a-mission-to-touch-the-sun Among other things, scientists hope to learn the secret of the corona's enormously high temperatures. The visible surface of the Sun is about 10,000 F – but, for reasons we don't fully understand, the corona is hundreds of times hotter, spiking up to several million degrees F. This is counterintuitive, as the Sun's energy is produced at its core. "It's a bit like if you walked away from a campfire and it suddenly got much hotter," said Nicky Fox. |

The Cold Matter experiment brought to the ISS by the Dragon spacecraft has produced a Bose Einstein Condensate of Rubidium atoms for a time much longer than on Earth due to its low temperature and the absence of gravity.Physicists are excited at this new instrument's capabilities. The USA is searching for private investors in the ISS after 2024 to keep it living. Tullio |

I hope at the end of 2024 that someone buys the ISS and places it in a fixed position around the moon.. Could even turn it into a hangar to build new space craft with a few mods done.. just a thought.. |

The ISS consists of 42 modules. 37 of them were put in orbit by the Shuttles, 5 by Russian rockets. It would not be easy to transfer them to a Moon orbit. Better to leave it where it stands and use its capabilities as long as possible. The SpaceX Dragon and Boeing Starliner capsules for astronauts should give America the means to shuttle astronauts to the ISS without the Russian Soyuz. Tullio |

Parker Solar Probe has lifted off from Cape Canaveral on a United Launch Alliance Delta IV Heavy Launcher. It is on its way to the Sun. Tullio |

Great new article about the trials and tribulations of test piloting new spaceships: https://www.newyorker.com/magazine/2018/08/20/virgin-galactics-rocket-man The mind is a weird and mysterious place |

ESA is about to launch Aeolus, a satellite conceived in 1999 capable of measuring wind velocity by emitting UV laser beams and recording their backscatter. It cost 550 million dollars but, according to a meteorologist cited by "Nature" it cold allow saving of billion dollars due to better meteorological forecasts. Tullio |

I guess many would say "But that's not Space Exploration". Well to do some of it you also need some experience and try tools that eventually could go further out into space. Now we are learning more of our own planet. https://www.esa.int/Our_Activities/Observing_the_Earth/Aeolus/Introducing_Aeolus Btw. In the 60's our only TV SVT showed this as an intro everyday:) https://www.youtube.com/watch?v=QTf3w5ln64U |

Except for perhaps not building any rockets either, for only that of making a couple of discoveries. |

ESA Aeolus has entered orbit. Next another laser-armed satellite will be launched by NASA on September 15 to monitor the thickness of ice in Greenland and Antarctica,besides the floating ice, ICESAT-2. Its laser beams will be in the optical range, green, while Aeolus uses UV beams. Tullio |

International Space Station astronauts plug leak with finger and tape after being hit with debris. https://www.telegraph.co.uk/science/2018/08/30/international-space-station-leaking-air-hit-space-debris/ The damage was found by closing hatches to each module one at a time, and European Space Agency (ESA) astronaut Alexander Gerst initially plugged the gap with his finger, before duct taping over the hole to prevent more air leaking into space. |

It is important to know if it were man-made debris or cosmic in nature. If Man-made then we need to put a proper space station much higher up. If not man-made then maybe we should think about doing a moon base first. It appears that we are starting our own Dyson Sphere with all of the space junk. Just as we are now trying to clean up the plastic from our oceans we need to try to clean up the millions of smaller objects that have befouled the orbital paths of our satellites and space stations. |

Space station air leak: someone drilled the hole, say Russians ‘Several attempts at drilling’ were made by a ‘wavering hand’ either on Earth or in orbit, in what could be accident or sabotage https://www.theguardian.com/science/2018/sep/05/space-station-air-leak-someone-drilled-the-hole-say-russians |

This ought to become interesting. Especially as IIRC they already reported that the culprit confessed that he patched it but didn't document it. But the conspiracy people have to get in a few dozen news cycles. |

The NASA Icesat-2 satellite has been launched from Vandenberg Air Force base in California. It has reached a polar orbit at 290 miles, which correspond to 466.697 km if they are statute miles. I cannot understand why NASA does not use the SI System. It carries a single instrument, the Atlas laser system which will measure the height of ice fields in Greenland and Antarctica with a precision of a few millimeters. Tullio |

I think that, in order to stay relevant to the American general public, NASA feels they must continue to use the Imperial measurement system in their reports to the public. I think that after the screw up several years ago with a Mars lander they use the metric system for all other purposes.
