<p>SpaceX has set the first launch of a “flight-proven” Falcon 9 rocket
for Thursday evening after running the booster through a hold-down
engine firing Monday at NASA’s Kennedy Space Center in Florida.</p>
<p>Nearly ready for its second trip into space, the Falcon 9’s first
stage booster ignited at launch pad 39A at 2 p.m. EDT (1800 GMT) and
throttled up to full power — roughly 1.7 million pounds of thrust — for a
few seconds as clamps held the rocket on the ground.</p>
<p>The brief ignition of the rocket’s nine Merlin 1D main engines
occurred after SpaceX’s launch team, overseeing a computer-controlled
sequencer, prepped the launcher by filling with its supplies of
super-chilled, densified RP-1 kerosene and liquid oxygen propellants.</p>
<p>SpaceX tweeted that the static fire test was completed successfully.
Engineers will review data from the launch rehearsal before convening a
launch readiness review later this week to formally clear the rocket for
liftoff.</p>
<p>The launch window opens at 6 p.m. EDT (2200 GMT) Thursday and extends for two-and-a-half hours.</p>
<p>The static fire test was set for Sunday, followed by a launch attempt
Wednesday, but preparations ran behind schedule over the weekend.</p>
<p>The launch is critical for SpaceX, which intends to re-fly its
rockets many times in a cost-cutting measure meant to reduce launch
prices and open more opportunities for space transportation and
exploration.</p>

<p>SpaceX founder and chief executive Elon Musk has a vision to send
large transport ships to Mars with human passengers and cargo to
eventually set up a self-sustaining civilization on the red planet.
Those lofty ambitions require spaceflight to become less expensive, and
reusability is a cornerstone to that objective.</p>
<p>While the company hopes to field future rockets that are rapidly
reusable, SpaceX engineers spent around four months refurbishing the
first stage booster set to launch this week. The core of the Falcon 9
first flew on April 8, 2016, with a Dragon supply ship on a cargo
mission to the International Space Station, then landed with the
assistance of rocket thrust on a mobile platform in the Atlantic Ocean.</p>
<p>The rocket was returned to Cape Canaveral, then trucked back to
SpaceX’s headquarters in Hawthorne, California, for thorough inspections
and refurbishment. The booster then traveled to SpaceX’s test site in
McGregor, Texas, for hold-down firings and returned to the Florida
launch a few weeks ago.</p>
<p>The rocket’s second stage, powered by a single Merlin 1D engine with a
nozzle extension, and payload fairing were manufactured new for this
week’s flight. SpaceX is working on retrieving and reusing the Falcon 9
fairing, which comes in two clamshell-like halves, while the second
stage will remain single-use for the foreseeable future.</p>
<p>With the static fire completed Monday, ground crews will roll back
the two-stage Falcon 9 rocket to its hangar at the southern perimeter of
pad 39A, where the SES 10 communications satellite awaits attachment to
the launcher.</p>
<p>The SES 10 spacecraft, tipping the scales at around 11,700 pounds
(5,300 kilograms), is already encapsulated inside the Falcon 9’s nose
fairing after being prepared for liftoff in a separate payload
processing facility a few miles to the south of pad 39A.</p>
<p>SES, a Luxembourg-based international telecom satellite operator,
announced its agreement with SpaceX in August 2016 to send the SES 10
satellite to orbit on a Falcon 9 rocket with a reused first stage.</p>
<p>While SpaceX and SES did not disclose terms of their contract for the
SES 10 launch, SpaceX president and chief operating officer Gwynne
Shotwell said last year the launch provider was offering a 10 percent
discount for customers willing to fly their payloads on reused boosters.</p>
<p>That discount should become steeper on future flights, according to
SpaceX officials. The company lists a regular commercial Falcon 9 flight
at $62 million.</p>
<p>SES is designed to broadcast video and television services across
Latin America. It was built by Airbus Defense and Space and assembled in
Toulouse, France.</p>
<p>Shotwell said earlier this month that the company intends to fly up
to six reused boosters this year. The maiden launch of SpaceX’s Falcon
Heavy rocket, driven by three Falcon 9 rocket cores strapped together,
is expected to utilize one or two previously-flown boosters, but SpaceX
has not publicly identified other missions that will reuse rocket
stages.</p>
<p>The weather outlook for Thursday evening’s launch window calls for a 70 percent chance of acceptable conditions.</p>
<p>The U.S. Air Force’s 45th Weather Squadron will watch for violations
of the cumulus cloud and thick cloud layer rules during the countdown.</p>
<p>“On Wednesday, a weak surface boundary will drape across the
Mid-Atlantic states and trail back into a developing storm system over
Texas,” the Air Force weather team wrote in a forecast issued Monday.
“On Thursday, the strengthening Texas storm system begins to track
northeasterly into the Tennessee Valley. Although the system and its
associated frontal boundary will not directly impact the spaceport until
late Friday and Saturday, upper-level cloudiness and added instability
ahead of the system is possible.”</p>
<p>The outlook calls for scattered clouds at 3,000 feet and broken
clouds at 28,000 feet, southeast winds at 10 to 15 mph, and a launch
time temperature of 80 degrees Fahrenheit.</p>
<p>If the launch is delayed to the backup day Friday, the weather is
forecast to worsen with a 60 percent chance of favorable conditions.</p>
<p>SpaceX’s landing platform is on the way to the landing zone a few
hundred miles east of Cape Canaveral to receive the Falcon 9 first
stage, which will again attempt a landing at sea after completing its
two-and-a-half minute firing to push SES 10 toward space.</p>
<p>A new robot is expected to debut after the booster touches down to
remotely safe and secure the rocket on the deck of the barge, or drone
ship, for the trip back to Port Canaveral.</p><p><font size="1"><span style="font-weight:normal"><a href="https://spaceflightnow.com/2017/03/27/hotfire-test-completed-ahead-of-milestone-falcon-9-launch-thursday/">https://spaceflightnow.com/2017/03/27/hotfire-test-completed-ahead-of-milestone-falcon-9-launch-thursday/</a></span></font></p><p><font size="1"><span style="font-weight:normal"><a href="https://garoa.net.br/wiki/Foguetes">https://garoa.net.br/wiki/Foguetes</a><br></span></font></p></div></div><div class="gmail_extra"><br><div class="gmail_quote">2017-03-27 16:40 GMT-03:00 Felipe Sanches <span dir="ltr"><<a href="mailto:juca@members.fsf.org" target="_blank">juca@members.fsf.org</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Agora é oficial.

Falcon 9 rocket's static fire test planned for today has been delayed
until Monday, likely pushing back the launch until Thursday evening.
SpaceX typically needs around three days to prepare for a launch after a
static fire test, a series of steps that include the attachment of a
satellite payload atop the rocket.</p><p>Launch preparations are running
behind schedule, and the launch window Wednesday and Thursday opens
around 4:59 p.m. EDT (2059 GMT).</p><p>The launch will send the SES 10
communications satellite into orbit aboard the first reused Falcon 9
rocket booster from launch pad 39A at NASA's Kennedy Space Center in
Florida.</p></div></div><div class="m_3095128657356734245HOEnZb"><div class="m_3095128657356734245h5"><div class="gmail_extra"><br><div class="gmail_quote">Em 24 de março de 2017 20:03, Felipe Sanches <span dir="ltr"><<a href="mailto:juca@members.fsf.org" target="_blank">juca@members.fsf.org</a>></span> escreveu:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><a href="https://www.bloomberg.com/news/articles/2017-03-24/spacex-launch-of-first-reused-rocket-to-mark-milestone-for-musk" target="_blank">https://www.bloomberg.com/news<wbr>/articles/2017-03-24/spacex-la<wbr>unch-of-first-reused-rocket-to<wbr>-mark-milestone-for-musk</a><br></div><div class="m_3095128657356734245m_7373361108310207296HOEnZb"><div class="m_3095128657356734245m_7373361108310207296h5"><div class="gmail_extra"><br><div class="gmail_quote">Em 22 de março de 2017 11:39, Felipe Sanches <span dir="ltr"><<a href="mailto:juca@members.fsf.org" target="_blank">juca@members.fsf.org</a>></span> escreveu:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="m_3095128657356734245m_7373361108310207296m_-859271528742836830m_-1513941098174033120datename"><span class="m_3095128657356734245m_7373361108310207296m_-859271528742836830m_-1513941098174033120launchdate">Nova data prevista: 4a feira, 29 de Março.<br></span></div><div class="m_3095128657356734245m_7373361108310207296m_-859271528742836830m_-1513941098174033120datename"><span class="m_3095128657356734245m_7373361108310207296m_-859271528742836830m_-1513941098174033120launchdate">Fonte: <a href="https://spaceflightnow.com/launch-schedule/" target="_blank">https://spaceflightnow.com/lau<wbr>nch-schedule/</a><br></span></div><div class="m_3095128657356734245m_7373361108310207296m_-859271528742836830m_-1513941098174033120datename"><span class="m_3095128657356734245m_7373361108310207296m_-859271528742836830m_-1513941098174033120launchdate"><br>NET March 29</span><span class="m_3095128657356734245m_7373361108310207296m_-859271528742836830m_-1513941098174033120mission"> • </span><span class="m_3095128657356734245m_7373361108310207296m_-859271528742836830m_-1513941098174033120mission">Falcon 9 • SES 10</span></div>
