The USA should be operating in EO today! But ignorant liberals have destroyed our capability!

Farewell Dione: Cassini Snaps Last Close Photos of Saturn Moon

The Cassini spacecraft recently got its last close views of Dione, a small icy moon orbiting Saturn, and the results are astounding.

Images returned from the Aug. 17 flyby show a mottled surface of craters and ice. One image shows Dione in front of the rings of Saturn, emerging from shadow. The closest approach brought the spacecraft to within 295 miles (474 kilometers) of the moon's surface.You can see more of Cassini's amazing Dione photos in our full gallery.

"I am moved, as I know everyone else is, looking at these exquisite images of Dione's surface and crescent, and knowing that they are the last we will see of this far-off world for a very long time to come," Carolyn Porco, Cassini imaging team lead at the Space Science Institute in Colorado, said in a statement from NASA's Jet Propulsion Laboratory.

Cassini has had four other close encounters with Dione since arriving at the Saturn system in 2004. Its closest approach was in December 2011, when it came within 60 miles (100 kilometers) of the satellite's surface.

Dione hangs in front of Saturn and its icy rings in this view, captured during Cassini's final close flyby of the icy moon. North on Dione is up. The image was obtained in visible light with the Cassini spacecraft wide-angle camera on Aug. 17, 2015.

During this last close encounter, the spacecraft only took a few images of Dione because the main goal of the flyby was to measure the moon's gravity, which will help scientists learn about its internal structure. This made imaging tricky because it wasn't Cassini's camera that was controlling where the spacecraft was "looking." Instead, Cassini was mostly studying Dione with its gravity science experiment, as well as instruments to measure the moon's magnetosphere (magnetic environment) and plasma (superheated gas), to help scientists understand processes on the moon's surface.

Cassini's last close encounter with Dione is one in a series of flybys scheduled for 2014. The spacecraft will make three final flybys of Enceladus — a geyser-spouting moon — on Oct. 14, 28 and Dec. 19. During the Oct. 28 flyby, the spacecraft will move through one of the plumes at a distance of as little as 30 miles (49 kilometers) from the surface.

Next year, Cassini's flyby schedule includes distant looks at the tiny Saturn moons of Daphnis, Telesto, Epimetheus and Aegaeon as well as a few icy moons. In the last year before the mission conclusion in late 2017, Cassini will move through the space between Saturn and its rings.

VIABLE US Manned Space Program-- THE ANSWER is HERE-- Gov. Support needed for several years THEN COMMERCIAL can TAKE OVER!

Don Nelson covers the proper steps the USA must take to have a viable manned space program. Government support is required since it is too expensive for private companies to go it on a strictly commercial basis. Eventually, the government can get out. 

As Don has stated before, this is only viable approach for the USA to have a manned program. Cots & sls/ Orion will not meet our needs---- means end of USA manned program. 

This link & nasaproblems.com details the correct USA approach!

Welcome to this week's issue of The Space Review:


CubeSats to Mars and beyond
---
As CubeSats take on an wider range of missions in Earth orbit, some are looking at how such small spacecraft could be used on interplanetary missions. Jeff Foust reports on those efforts discussed at a recent conference, from serving as a communications relay for a Mars lander mission to being Mars landers themselves.

Second horizon
---
Long before New Horizons lifted off on its mission to Pluto, the project team was proposing the development of a second, similar spacecraft. Dwayne Day discusses that proposal and what happened to it at NASA and in the halls of Congress.
http://www.thespacereview.com/article/2813/1

Major unfinished business in the the US space program
---
With less than 18 months left in the current Presidential administration, some argue there's little chance of major new space initiatives from the White House in that time. However, Vid Beldavs, in an open letter to the President, asks him to support a new emphasis on lunar exploration in cooperation with international and commercial partners.

The risks of Mars
---
Many people consider a human mission to Mars with trepidation given the risks involved, including the potential loss of life. Frank Stratford argues that humanity needs to accept and even embrace those risks, given the much greater benefits such missions offer.

Review: Moonshots and Snapshots of Project Apollo
---
The history of the Apollo program has been told time and time again, often using the same familiar set of images. Jeff Foust reviews a book that, like a similar one on Mercury and Gemini, dips into archives for some rare glimpses of those missions.
http://www.thespacereview.com/article/2810/1


If you missed it, here's what we published in our previous issue:


Red planet rumble
---
During the annual Mars Society conference last week, the CEO of Mars One and a member of his technical team debated two critics of the one-way venture from MIT. Dwayne Day recaps the event, which exposed a lack of detail in Mars One's technical plans.
http://www.thespacereview.com/article/2809/1

The unnatural selection of planetary missions
---
The process of sorting through dozens of proposals for NASA missions is a thankless job for an anonymous group of reviewers. Ralph Lorenz explains the challenges involved with developing and reviewing mission proposals.
http://www.thespacereview.com/article/2808/1

A funding breakthrough for SETI
---
Efforts in the search for extraterrestrial intelligence got a boost last month when a Russian billionaire pledged $100 million over ten years for SETI projects. Jeff Foust reports what that $100 million means for SETI projects and who might be left out, at least for now.
http://www.thespacereview.com/article/2807/1

Harnessing "The Martian"
---
In October, the film version of the bestselling book "The Martian" hits theaters. Rick Zucker and Chris Carberry discuss how space advocates can use the release of the film about a fictional human Mars mission to build support for the real thing.

Apollo 13 splashes down in Oshkosh
---
Forty-five years after their dramatic mission, the two surviving members of the Apollo 13 crew joined two others involved with the mission at the EAA AirVenture show last month. Eric Hedman describes their presentation on the mission, and what the famous movie got wrong.

End of US Manned Space program--- comment to open letter to Bho -- space news

Expat · 1 hour ago

"No one asks "what is the President's vision for transporting people from New York to Paris..." 

Maybe because there already is a market in the private economy for flights from NY to Paris? 

But there is NOT a market in the private economy for SpaceX to sell flights to and from orbit. This will be especially true in less than ten years when the Space Station goes away (and ten years is a best case scenario). 

Here's a better analogy: 

Smart people thought there was a market for commercial supersonic transport forty years ago. And after the technology was in hand and operational, that turned out (for a variety of reasons) NOT to be the case. Concorde service survived as long as it did because two governments subsidized its operations. When those subsidies were withdrawn, British Air and Air France retired the fleet. The Concordes were still flightworthy, but no one could afford to fly them (sound familiar? substitute Shuttle for Concorde...) 

Same thing is looming for SpaceX and Boeing's manned capsules---when the ISS is retired (assuming they get their capsules operational before then) the government subsidies will likewise go away. And so will their manned capsules. 

You can thank the Obama Administration for that on many levels, including his economic policies that have failed to produce US economic growth at the 5-6% levels we used to enjoy. So lower economic growth (both in the US and abroad) the fewer customers you will have for SpaceX to sell its very, very expensive tickets to for billionaire space tourists. No ISS? No market for space tourists? No SpaceX or Boeing capsules flying. 

The End. Of US manned spacefllight, anyway.
