Race is on to lure new SpaceX launchpad - 0 views

  • A record-breaking mission to the International Space Station has triggered another space race back on Earth, with Florida competing against Texas and Puerto Rico for the chance to land a new launchpad for Space Exploration Technologies Corp., or SpaceX, and its ambitious line of Falcon rockets.
  • none of the rivals has made public the incentives each is offering, the numbers are certain to be in the millions of dollars.
  • The stakes are high: hundreds of good-paying jobs at SpaceX and supporting companies that would pop up around its operation, as well as the prestige - at a time when NASA is no longer flying its own rockets - of serving as home to the commercial space industry's most successful startup.

  • Musk recently indicated that Texas might have the inside track
  • Florida officials acknowledge the competition is keen. They're hoping to leverage the fact that SpaceX already has one launchpad at Cape Canaveral

  • Florida officials also note they have a track record of helping the company. Space Florida, the state's aerospace booster, has invested more than $8.5 million so far to help establish the company at Cape Canaveral.
  • Florida faces one obstacle that has no immediate solution. The Air Force and NASA already use Cape Canaveral for launches - of government satellites and space probes - and SpaceX at times could be forced to wait its turn until the range is clear.

  • Puerto Rican officials are making geography a core argument in their pitch.
  • Puerto Rico is closer to the equator than Cape Canaveral or Brownsville, which means SpaceX rockets would use less fuel (and thus cost less to launch to orbit) because rockets get more of a "boost" from Earth's rotation near the equator.

SpaceX's First Mission to the Space Station: How It Will Work | Dragon COTS 2/3 Flight ... - 0 views

  • SpaceX's unmanned Dragon capsule is due to deliver food, supplies and science experiments
  • SpaceX is one of two companies with NASA contracts for robotic cargo delivery flights (Virginia's Orbital Technologies Corp. is the other), but is the first to actually try a launch
  • Here's how the robotic mission is expected to play out:
  • ...50 more annotations...
  • Step 1: Launch
  • from Cape Canaveral Air Force Station in Florida. SpaceX has use of the facility's Space Launch Complex 40
  • The initial ascent is powered by Falcon 9's first stage, consisting of nine SpaceX Merlin 1C rocket engines
  • Step 2: Main Engine Cut Off/Stage Separation
  • At a little before 180 seconds into the flight, the Falcon 9's first stage engines will cut off, and the first stage will drop off, falling back to Earth
  • the booster's second stage engines should start, further propelling the vehicle into orbit.
  • Step 3: Payload Separation
  • Around 9 minutes into the flight, the Dragon capsule should separate from Falcon 9's second stage and orbit on its own
  • capsule will deploy its solar arrays to start soaking up energy from the sun
  • Dragon is on its own and must maneuver using its onboard thrusters
  • Step 4: Orbital Checkouts
  • Dragon will begin a series of checkouts to make sure it's functioning as designed and ready to meet up with the station
  • test out its abort system to prove it can terminate its activities and move away from the space station if something goes wrong.
  • demonstrate its performance in free drift phase, with thrusters inhibited
  • Teams on the ground will lead the vehicle through tests of
  • Absolute GPS (AGPS) system, which uses global positioning system satellites to determine its location in space
  • Step 5: Fly-Under
  • fire its thrusters to perform a fly-under of the International Space Station
  • to 1.5 miles (2.5 kilometers) below the outpost
  • make radio contact with the station using a system called the COTS Ultra?high frequency Communication Unit to communicate.
  • Dragon will also test a secondary locator system called the relative GPS system, which uses the spacecraft's position relative to the space station to establish its coordinates
  • the six-person crew inside the orbiting laboratory will be monitoring their new visitor
  • use a crew command panel onboard the station to communicate with the capsule and send it a command to turn on a strobe light.
  • After completing the fly-under, Dragon will loop out in front, above and then behind the space station to position itself for docking.
  • Step 6: Rendezvous
  • during Dragon's fourth day of flight, the spacecraft will fire its thrusters again to bring it within 1.5 miles (2.5 kilometers) of the space station
  • there, NASA's Mission Control team in Houston will run through a "go-no go" call to confirm all teams are ready for rendezvous
  • If everyone is "go," Dragon will inch closer, to about 820 feet (250 meters) away from the space station.
  • series of final checkouts will be performed to make sure all of Dragon's location and navigation systems are accurate
  • If all looks good, Dragon's SpaceX control team on the ground will command the vehicle to approach the space station
  • When it reaches 720 feet (220 meters), the astronauts onboard the outpost will command the capsule to halt.
  • After another series of "go-no go" checks
  • approach to 656 feet (200 meters), and then 98 feet (30 meters), and finally 32 feet (10 meters), the capture point.
  • Step 7: Docking
  • Mission Control will tell the space station crew they are "go" for capturing Dragon
  • astronaut Don Pettit will use the station's robotic arm to reach out and grab Dragon, pulling it in to the bottom side of the lab's Harmony node, and then attaching it.
  • The next day, after more checkouts, the crew will open the hatch between Dragon and the station.
  • Over the coming weeks, the astronauts will spend about 25 hours unpacking the 1,014 pounds (460 kilograms) of cargo that Dragon delivers
  • none of the cargo is critical (since this is a test flight),
  • capsule will arrive bearing food, water, clothing and supplies for the crew.
  • Step 8: Undocking
  • Dragon is due to spend about 18 days docked at the International Space Station.
  • the station astronauts will use the robotic arm to maneuver the capsule out to about 33 feet (10 meters) away, then release it. Dragon will then use its thrusters to fly a safe distance away from the laboratory.
  • Step 9: Re-entry
  • About four hours after departing the space station, Dragon will fire its engines to make what's called a de-orbit burn
  • will set the capsule on a course for re-entry through Earth's atmosphere
  • spacecraft is equipped with a heat shield to protect it from the fiery temperatures of its 7-minute re-entry flight.
  • Step 10: Landing
  • due to splash down in the Pacific Ocean to end its mission
  • There, recovery crews will be waiting to collect the capsule about 250 miles (450 kilometers) off the West Coast of the United States

  • Three of the check valves were actually different from the prior check valves that had flown – in a very tiny way. Because of the tiny change they got stuck
  • able to write some new software in real time and upload that to Dragon to build pressure upstream of the check valves and then released that pressure- to give it a kind of a kick
  • that got the valves unstuck and then they worked well
  • difficulty communicating with the spacecraft because it was in free drift in orbit
  • worked closely with the Air Force to get higher intensity, more powerful dishes to communicate with the spacecraft and upload the software
  • there had been a small design change to the check valves by the supplier
  • supplier had made mistakes that we didn’t catch
  • You would need a magnifying glass to see the difference
  • SpaceX had run the new check valves through a series of low pressurization systems tests and they worked well and didn’t get stuck. But SpaceX had failed to run the functional tests at higher pressures
  • SpaceX will revert to the old check valves and run tests to make sure this failure doesn’t happen again

SpaceX Launches Six Commercial Satellites on Falcon 9; Landing Test Ends in "Kaboom" - 0 views

  • SpaceX successfully launched six ORBCOMM advanced telecommunications satellites into orbit on Monday, July 14, to significantly upgrade the speed and capacity of their existing data relay network.
  • SpaceX also used this launch opportunity to try and test the reusability of the Falcon 9′s first stage and its landing system while splashing down in the ocean
