Space….The Good News And The Bad

Hope your Sunday is as relaxing as mine…..

We have a Space Force on the drawing boards as another military branch….first Obama and now Trump are considering the possibility……so we need to keep an eye on what is happening with our space programs……

First the Good News…….the Parker Solar Probe…..

NASA’s Parker Solar Probe is now closer to the sun than any spacecraft has ever gotten. Parker on Monday surpassed the record of 26.6 million miles set by Helios 2 back in 1976, the AP reports—and it will keep getting closer to the sun until it flies through the corona, or outer atmosphere, for the first time next week, passing within 15 million miles of the solar surface. Parker will make 24 close approaches to the sun over the next seven years, ultimately coming within just 3.8 million miles. “We’ve now come closer to our star than any other spacecraft in history,” Andy Driesman, the project manager for the probe, said in a statement, per Gizmodo. “It’s a proud moment for the team.”

Motherboard notes that the probe is protected by a Thermal Protection System (TPS) heat shield, which has been tested to endure temps up to 3,000 degrees Fahrenheit. It’s also designed to keep the probe’s instruments safe from radiation and to help the probe make an easier transition when it heads back to the relative chilliness of deep space. Launched in August, Parker was on track to set another record late Monday night, about to surpass Helios 2’s speed record of 153,454 miles per hour, relative to the sun. (Is your name flying close to the sun with Parker?)

And now the bad…..the Kepler Telescope has given scientist so much to think about has possibly died…..

NASA’s elite planet-hunting spacecraft has been declared dead, just a few months shy of its 10th anniversary. Officials announced the Kepler Space Telescope’s demise Tuesday, the AP reports. Already well past its expected lifetime, the 9 1/2-year-old Kepler had been running low on fuel for months. Its ability to point at distant stars and identify possible alien worlds worsened dramatically at the beginning of October, but flight controllers still managed to retrieve its latest observations. The telescope has now gone silent, its fuel tank empty. Kepler discovered 2,681 planets outside our solar system and even more potential candidates. It showed us rocky worlds the size of Earth that, like Earth, might harbor life. It also unveiled incredible super Earths: planets bigger than Earth but smaller than Neptune.

Kepler opened the gate for mankind’s exploration of the cosmos,” said retired NASA scientist William Borucki, who led the original Kepler science team. Adds NASA’s astrophysics director Paul Hertz, “It has revolutionized our understanding of our place in the cosmos. Now we know because of the Kepler Space Telescope and its science mission that planets are more common than stars in our galaxy.” Kepler focused on stars thousands of light-years away; a successor to Kepler launched in April, NASA’s Tess spacecraft, has its sights on stars closer to home and has already identified some possible planets. Now 94 million miles from Earth, Kepler should remain in a safe, stable orbit around the sun. Flight controllers will disable the spacecraft’s transmitters, before bidding a final “good night.”

It had a magnificent run……just look at the site for more info….

The centuries-old quest for other worlds like our Earth has been rejuvenated by the intense excitement and popular interest surrounding the discovery of hundreds of planets orbiting other stars. There is now clear evidence for substantial numbers of three types of exoplanets; gas giants, hot-super-Earths in short period orbits, and ice giants. The challenge now is to find terrestrial planets (i.e., those one half to twice the size of the Earth), especially those in the habitable zone of their stars where liquid water might exist on the surface of the planet.

The Kepler Mission is specifically designed to survey our region of the Milky Way galaxy to discover hundreds of Earth-size and smaller planets in or near the habitable zone and determine the fraction of the hundreds of billions of stars in our galaxy that might have such planets.

Sundays are for relaxation….try it you will like it…..chuq

  1. As much as I can see the reasoning behind such exploration, I can’t help thinking the money and research time would be better spent trying to keep life on this planet stable first. Looking for somewhere to ‘escape’ to is all very well, but we all know that option will only be for the elite few.
    Best wishes, Pete.

    1. Pete, we need to hurry and find another planet to destroy, this one is beyond repair, or it is naturally going through another heat/then freeze cycle it has gone through for billions of years.
