Keep up the good work DocM, one of my favorite threads on here
@elonmusk Speaking of F9R, how do you plan to recover the FH center core? Seems it would be going too fast/far for direct boost-back.
Elon Musk @elonmusk
@2552nsf Yeah, that is super tricky. Will have to sacrifice a lot of payload to boost back or land on ocean platform.
JP Burke @yatpay
@elonmusk Is it possible to launch from Texas and land in Florida?
Elon Musk @elonmusk
@yatpay Side boosters fall short & center core goes too far + Florida is heavily populated. Landing permission tricky

SpaceX To Refly Columbia Plant Growth Experiment
CAPE CANAVERAL, Fla. — A plant growth experiment lost in the 2003 Space Shuttle Columbia accident is being revamped for reflight to the international space station aboard the next Space Exploration Technologies Corp. (SpaceX) Dragon cargo ship.
The experiment, called BioTube, is intended to test if a strong magnetic field can replace gravity in influencing the direction plant roots grow in space.
“Right after the germination, the roots decide which way to grow. So the entire experiment is really interested in about the first 48 hours of how these roots grow when they are subjected to a magnetic field with no gravity,” said Don Platt, president of Melbourne, Fla.-based Micro Aerospace Solutions, which is developing the revamped BioTube.
The experiment is a follow-on to one that flew on STS-107, the last flight of Columbia, which was destroyed during re-entry following a 16-day research mission. All seven astronauts aboard were killed.
“The experiment worked quite well but obviously the payload was lost,” said Platt, who was previously employed by experiment developer Bionetics Corp. here.
Platt’s company is now preparing the backup unit, which did not fly on Columbia, to be launched on SpaceX’s third space station cargo run. NASA’s launch schedule shows the mission is slated for liftoff in November.
“They’ve changed the seeds because of genetic mapping and what they have maps of now, so we’ve redone the experiment totally to fly to the international space station,” Platt said.
BioTube, which is about the size of microwave oven, originally flew inside a Spacehab module in the shuttle’s cargo bay. It was part of an overall research initiative to understand how gravity-sensing systems in plants and small organisms operate.

SpaceX has just notified us that there will be, baring any unforeseen problems, a 9 engine test at around 8pm this evening.

1st firing of Falcon 9-R advanced prototype rocket. Over 1M lbs thrust, enough to lift skyscraper pic.twitter.com/AUCsWTw77E
@williamricci6 50% higher. ~1.3 M lbs sea level and ~1.5 M lbs vacuum thrust. Will be 60% higher with some tweaks.

MCGREGOR (June 7, 2013)—Residents accustomed to the daily roar of tests at the SpaceX facility in McGregor may do a double-take when the private space exploration company conducts a test it says will be significantly louder.
The test could occur as early as Friday afternoon and could last for as long as several minutes, the company said.
