A close and realistic look at SpaceX’s schedule for 2013.
Not surprisingly, it is expected that the company will fail to achieve all these scheduled launches and milestones. It is also likely that the company will achieve most, given its very successful track record so far.
An evening pause:
New research suggests that the high radiation experienced by astronauts on interplanetary journeys could accelerate the onset of Alzheimer’s.
Some caveats: This research was done on Earth with mice. It also assumes that it will be impossible to protect astronauts from all types of radiation while on their journey.
Schedule update: Orbital Sciences will do a hot fire launchpad test of its Antares rocket in January, followed by a test launch to orbit in February, and a first flight of the Cygnus capsule in April.
An ion test engine has set a new record for continuous operation.
The NEXT ion thruster is one of NASA’s latest generation of engines. With a power output of seven kilowatts, it’s over twice as powerful as the ones used aboard the unmanned Dawn space probe. Yet it is simpler in design, lighter and more efficient, and is also designed for very high endurance. Its current record of 43,000 hours is the equivalent of nearly five years of continuous operation while consuming only 770 kg (1697.5 lbs) of xenon propellant.
This engine will make the unmanned exploration of the asteroid belt extremely easy and practical.
The competition heats up: It appears that SpaceX and Orbcomm have finalized their launch agreement.
On December 21, 2012, ORBCOMM Inc. (Nasdaq: ORBC) and Space Exploration Technologies Corp. (SpaceX) entered into a Launch Services Agreement pursuant to which SpaceX will provide launch services for the carriage into low-Earth-orbit of up to 18 ORBCOMM second-generation commercial communications satellites currently being constructed by Sierra Nevada Corporation.
The agreement schedules the launches for sometime between the second quarter of 2013 and the second quarter of 2014, subject to normal scheduling changes.
This is a strong endorsement by Orbcomm of SpaceX’s Falcon 9 rocket, despite the engine problem which prevented an Orbcomm prototype satellite from reaching its correct orbit on the last Falcon 9 launch. Also, note that Sierra Nevada is building the satellites, thereby giving that company a firm foundations while it also builds its Dream Chaser manned spacecraft.
A United Kingdom effort to drill down almost two miles to reach buired Lake Ellsworth in Antarctica has been abandoned.
The article doesn’t mention the failure of a boiler two weeks ago, which from their website apparently delayed drilling until this week.
SpaceX’s Grasshopper rocket successfully did a vertical take off and landing to a height of 130 feet last week. With video.
This is very cool engineering, but I remain skeptical any first stage rocket could carry enough fuel to both return to Earth vertically and also provide its payload enough thrust to get into orbit.
What the future was supposed to be like.
The Soyuz capsule with ISS’s new crew of three astronauts has successfully docked with the station.
NASA successfully completed a set of tests of the parachutes for the Orion capsule on Thursday.
