<b>NASA Tests LDSD 'Flying Saucer'</b><br><br> <br><br> NASA mission managers are preparing for a launch attempt today, Saturday, of a high-altitude balloon carrying the Low-Density Supersonic Decelerator (LDSD) test vehicle to the edge of space on a test flight from the U.S. Navy's Pacific Missile Range Facility in Kauai, Hawaii.<br><br> <br><br> Live coverage is on now. <br> Today's balloon launch window extends from approximately 8:15 a.m. to 9:00 a.m. HST (11:15 a.m. to noon PDT, 2:15 to 3 p.m. EDT). The balloon will take approximately 2-3 hours to achieve float conditions. Shortly thereafter, the test vehicle will be released from the balloon and the test will begin.<br><br> <br><br> Check back on <a href="http://bit.ly/NASALDSD" target="_blank">http://bit.ly/NASALDSD and on our Twitter sites: @NASA_Technology, @NASA, @NASAJPL and @NASA_Marshall to get the latest updates on the mission.<br><br> <br><br>

&lt;br&gt;&lt;br&gt; ===============================&lt;br&gt;&lt;br&gt; &lt;br&gt;&lt;br&gt; &lt;b&gt;OCO-2 OBSERVATORY LAUNCH COVERAGE EVENTS&lt;/b&gt;&lt;br&gt;&lt;br&gt; &lt;br&gt;&lt;br&gt; The launch of NASA's Orbiting Carbon Observatory-2 mission (OCO-2) at Vandenberg Air Force Base (VAFB) in California, is scheduled for Tuesday, July 1. Liftoff from Space Launch Complex 2 aboard a United Launch Alliance Delta II rocket at VAFB is targeted for 2:56 a.m. PDT (5:56 a.m. EDT, 0956 UTC).&lt;br&gt;&lt;br&gt; &lt;br&gt;&lt;br&gt; OCO-2 is NASA's first mission dedicated to studying atmospheric carbon dioxide, the leading human-produced greenhouse gas driving changes in Earth's climate. OCO-2 will provide a new tool for understanding the human and natural sources of carbon dioxide emissions and the natural "sinks" that absorb carbon dioxide and help control its buildup.&lt;br&gt;&lt;br&gt; &lt;br&gt;&lt;br&gt; &lt;b&gt;OCO-2 Prelaunch News Conferences&lt;br&gt;&lt;br&gt; June 29 4 p.m. PDT (7 p.m. EDT, 2300 UTC)&lt;/b&gt;&lt;br&gt;&lt;br&gt; &lt;br&gt;&lt;br&gt; Participants in the prelaunch news conference will be:&lt;br&gt;&lt;br&gt; • Betsy Edwards, OCO-2 Program Executive - NASA Headquarters&lt;br&gt;&lt;br&gt; • Tim Dunn, NASA Launch Manager - Kennedy Space Center&lt;br&gt;&lt;br&gt; • Vernon Thorp, Program Manager, NASA Missions - United Launch Alliance&lt;br&gt;&lt;br&gt; • Ralph Basilio, OCO-2 Project Manager - Jet Propulsion Laboratory&lt;br&gt;&lt;br&gt; • Lt. Joseph Round, Launch Weather Officer, 30th Operations Support Squadron VAFB&lt;br&gt;&lt;br&gt; &lt;br&gt;&lt;br&gt; An OCO-2 mission science briefing will be held immediately following the prelaunch news conference. Presenting the mission science objectives will be:&lt;br&gt;&lt;br&gt; • Ken Jucks, OCO-2 Program Scientist - NASA Headquarters&lt;br&gt;&lt;br&gt; • David Crisp, OCO-2 Science Team Leader - JPL&lt;br&gt;&lt;br&gt; • Annmarie Eldering, OCO-2 Deputy Project Scientist - JPL&lt;br&gt;&lt;br&gt; &lt;br&gt;&lt;br&gt; &lt;b&gt;OCO-2 #NASASocial&lt;br&gt;&lt;br&gt; June 30 9:30 a.m. PDT (12:30 p.m. PDT, 1630 UTC)&lt;/b&gt;&lt;br&gt;&lt;br&gt; &lt;br&gt;&lt;br&gt; NASA will host a live broadcast featuring interactive discussions, including an OCO-2 mission overview, launch details and an engineering and science panel. &lt;br&gt;&lt;br&gt; &lt;br&gt;&lt;br&gt; &lt;b&gt;OCO-2 Launch&lt;br&gt;&lt;br&gt; July 1 12:45 a.m. PDT (3:45 a.m. PDT, 0745 UTC) &lt;/b&gt;&lt;br&gt;&lt;br&gt; Watch live coverage on NASA-TV &lt;a href="http://www.nasa.gov/nasatv" target="_blank"&gt;http://www.nasa.gov/nasatv



On launch day, July 1, NASA TV launch commentary coverage of the countdown will begin at 12:45 a.m. PDT (3:45 a.m. EDT). Launch is targeted for 2:56 a.m. PDT (5:56 a.m. EDT). The flight azimuth of the Delta II after liftoff will be 196 degrees. Spacecraft separation from the rocket occurs 56 minutes, 15 seconds after launch.&lt;br&gt;&lt;br&gt; &lt;br&gt;&lt;br&gt; &lt;b&gt;OCO-2 Post-Launch News Conference&lt;br&gt;&lt;br&gt; July 1 5:30 a.m. PDT (8:30 a.m. EDT, 1230 UTC)&lt;/b&gt;&lt;br&gt;&lt;br&gt; &lt;br&gt;&lt;br&gt; After launch, an OCO-2 post-launch news conference will be held at Vandenberg. Observatory and mission officials will provide the spacecraft status and discuss its state of health.&lt;br&gt;&lt;br&gt; &lt;br&gt;&lt;br&gt; ==============================&lt;br&gt;&lt;br&gt; &lt;br&gt;&lt;br&gt; NASA's Jet Propulsion Laboratory invites you to watch live and chat about everything from Mars rovers to monitoring asteroids to cool cosmic discoveries.
