One of NASA's Technology Demonstration Missions, LDSD is often mentioned in other threads, but has none of its own...until now.

In the "LIVE" section because flight tests are expected within days (at the time of this post). And an unusual flight test it will be, see below.

There are also quite a few posts on this upcoming test in the "Mars EDL Technologies" thread:

The "countdown clock" is now running. Launch is Thursday, June 5, no exact time has been given yet. I am assuming "launch" means releasing the balloon.

LDSD: The Great Shakeout Test For Mars

Published on Jun 3, 2014
NASA readies for the experimental flight of the Low-Density Supersonic Decelerator (LDSD), a test vehicle designed for landing larger payloads on Mars. The saucer-shaped vehicle will undergo its first test flight in June 2014 from the U.S. Navy's Pacific Missile Range Facility in Kauai, Hawaii.

There was mention of the LDSD "saucer" during Robin Quivers NEWS portion of the Howard Stern Show, on Sirius/XM Radio yesterday.
Creating interest on every level cant hurt. 25 million Sirius subscribers, mostly Howard Stern subscribers.

News Briefing Previews Test of Saucer Shaped Vehicle

Published on Jun 4, 2014
NASA held a news conference from the U.S. Navy's Pacific Missile Range Facility in Kauai, Hawaii on June 2 about the upcoming test of the Low-Density Supersonic Decelerator (LDSD) project. During the test, a rocket-powered, saucer-shaped test vehicle will be flown into near-space. LDSD could lead to inflatable spacecraft systems capable of safely landing heavier and larger payloads than ever before on planets with atmospheres. June 3 is the first of six potential launch dates. NASA will issue launch advisories via the mission website, media advisories and on Twitter at: https://twitter.com/NASA_Technology and https://twitter.com/NASA

There's a bunch of news reports on LDSD at

http://mars.jpl.nasa.gov/msl/news/whatsnew/index.cfm?y=2014&t=

Notably, the attempts on 3 and 5 June were cancelled due to weather. The next available attempt is on 7 June. The scheduled time on 3 June was 2:30 p.m. EDT (6:30 pm GMT) which I guess would be the same time for the latter scheduled attempts. Attached are some photos and the press kit.

"2nd Update: Monday, June 2, 2014 - 5:30 PM EDT
Due to weather conditions, there will be no launch of the LDSD test vehicle Tuesday, June 3. Other potential launch dates include June 5, 7, 9, 11 and 14. Launch decision for Thursday, June 5 will be made on Wednesday, June 4. Check back with us for updates."

"3rd Update: Wednesday, June 4, 2014 - 4:20 PM EDT
Due to weather conditions, there will be no launch of the LDSD test vehicle Thursday, June 5. Other potential launch dates include June 7, 9, 11 and 14. The decision to move forward with another launch attempt of the LDSD test is made the day before each launch opportunity date."

Any indication on what the weather conditions are that keep delaying it? I would guess winds, because balloons need no wind. But are there issues with visibility?

I have a hard time believing that there's been a week of "bad weather" in Hawaii. "Weather" must refer to the conditions at high altitude; high-level winds or the jet stream or something.

They need winds to carry the balloon in the correct direction away from the islands and into the range.

What a great thread. Well done for getting all the resources in. We'll absolutely cover this.

Have you been to Hawaii? It has a reputation as paradise, but that doesn't mean that it is perfectly sunny and 72 degrees every single day everywhere. For one thing, it's an island chain, so whereas it can be gorgeous in Honolulu for weeks on end, that doesn't mean that 100 miles to the northwest it's perfect. I've heard that the northwestern islands get more wind, and when I was on Maui--and it was gorgeous--somebody told me that it had been overcast and windy for the three previous weeks.

Sunday, June 8 Update
June 8, 2014 - 8:12 PM EDT
    The winds aren't cooperating for our launch of the Low Density Supersonic Decelerator (LDSD) tomorrow, Monday, June 9. Other potential launch dates include June 11 and 14. Wind conditions have been the prevailing factor in the launch delays they have to be just the right speed and direction in order to launch the balloon that carries the LDSD test vehicle. The launch decision for Wednesday, June 11 will be made on Tuesday, June 10. Check back with us for updates.

LDSD Launch Status Updates

Tuesday, June 10 Update

June 10, 2014 - 9:21 PM EDT

Mission managers are proceeding with preparations for a launch attempt tomorrow morning, Wednesday, June 11 of a high altitude balloon carrying the Low Density Supersonic Decelerator (LDSD) test vehicle to the edge of space on a test flight of the flying saucer. At present, weather forecasted for tomorrow morning is close, but not within launch parameters. Mission managers will evaluate latest weather conditions again early tomorrow morning, to confirm favorable conditions. The Wednesday launch window extends from 8:15 a.m. to 9:00 a.m. HST (11:15 a.m. to 12-noon PDT). Check back here and on our Twitter sites: @NASA_Technology, @NASA, @NASAJPL and @NASA_Marshall to get the latest updates on the mission. #321TechOff #LDSD
