On NASA's suborbital launch schedule is a mission planned for November 2014:
12.082CR LARC-NESC/Reimbursable (Taurion Booster) / SPRINT target vehicle
Does anyone have any info on the Taurion booster and the SPRINT target vehicle?
The "Tau(r)" in Taurion refers apparently to the Taurus (Honest John) rocket motor, as the lates Rocket Report (
http://rscience.gsfc.nasa.gov/keydocs/Rocket_Report_3rd_quarter_2014.pdf) shows the preparation of a Taurus motor casing. The "(r)ion" in the name might perhaps hint to a Orion upper stage.

China Conducts Flight Test of New Mobile ICBM.
China's military has conducted the first flight test of a new variant of one of its road-mobile intercontinental ballistic missiles in a sign that Beijing is increasing its strategic strike capability against the United States.
The test of a new DF-31B missile was conducted Sept. 25 from a missile test range in central China.
A Pentagon spokeswoman declined to provide details of the test.
“We continue to monitor China’s military modernization, including its missile tests,” Cynthia O. Smith, the spokeswoman, told the Washington Free Beacon.
No details of the missile test could be learned, but the test was believed to have been carried out from China’s Wuzhai test facility.

In relation to the article below one of the ways of resolving this is to take the booster out of the equation and find a way for the vehicle to accelerate itself to the necessary velocity. I know that's easier said than done but it looks like with people such as REL and their engine technology in the mix that it isn't a completely impossibility to achieve this.
The problem with hypersonics is getting that fast in the first place. A significant number of attempts to fly beyond five times the speed of sound have failed not due to the advanced airframe or propulsion technology being tested, but because of the rocket booster needed to reach that speed. These failures have hindered understanding of complex hypersonic phenomena and hampered development of high-speed vehicles.
The latest casualty may be the second test of the U.S. Army Hypersonic Weapon (AHW—see concept image), which ended prematurely in August when its launch vehicle was deliberately destroyed seconds after lift-off from the Kodiak Launch Complex in Alaska. A failure of the booster’s stabilizing fins is suspected.
As the U.S. moves into development of high-speed strike weapons, it faces the challenge of perfecting not only the hypersonic vehicle but also a tactical booster that can reliably accelerate an unpowered glider or powered cruiser to its operational speed. Based on history, doing both will be a challenge.
In June 2001, the first attempt to fly NASA’s scramjet-powered X-43A ended when its Pegasus booster lost control following an elevon failure seconds after release from the B-52 mothership. The next two flights, in 2004, were successful and the X-43A reached Mach 9.6.

The Experimental Institute for Space Center of Taiwan launch a souding-rocket on October 7 from the Jiupeng base, Pingtung. Launch took place at 11:10 local.
Flight durantion was 520 seconds and mission objective was ionospheric studies.
Taiwan plans to launch a satellite (Fu Wei V) on 2015.

On 5 June 2013 and 2 March 2014.
http://space.skyrocket.de/doc_lau/taiwan-sounding-rocket.htm
Thanks Gunter. Your page says 27 March for SR 9.
Which is correct - i made a typo in the posting above. Sorry.
Actually 26 Mar?
The NSPO page says 2134 local, Mar 26 = I think 1334 UTC Mar 26
26 March seems to be correct - apparently i made a mistake in time zone conversion.

USAF Scientific Advisory Board
Technology Readiness for Hypersonic Vehicles
Terms of Reference
Background
Recent successes with the X-51 Program and an increasing focus on access to denied airspace have renewed interest in pursuing hypersonic weapon systems. Previous studies identified as a shortfall the lack of the light-weight, high temperature, and high strength materials needed for such a vehicle, both on its aerodynamic surfaces and in its propulsion system. Additionally, recent hypersonic testing has experienced anomalies in propulsion flow-path predictability and flight control effectiveness. To evaluate the eventual military utility of air-breathing hypersonics technology, the Air Force needs to identify overall system concepts that provide that utility, develop confidence in the requisite materials, propulsion, and flight control technologies for the vehicle, address the sensors, communications, and other auxiliary sub-systems needed for the overall concept, and effectively integrate all those technologies.
Charter
The study will:
Identify the relevant operating regimes, in particular the flight speeds and altitudes, based on projected USAF concepts of operations for hypersonic systems including ISR and strike.
Examine overall system concepts for hypersonic weapon systems for those missions and flight regimes. Evaluate the military utility of those systems and identify technologies needed to achieve that utility. Compare the value of those systems to similar non-hypersonic systems.
Assess the maturity of the modeling and sub-system testing capabilities needed to understand the material and structural requirements, aerodynamic performance, propulsion, and control requirements for flight in the relevant operating regimes.
Evaluate existing and emerging materials, structural concepts, propulsion systems, flight control designs, sensors, communications systems, and operator control architectures to determine their readiness to enter a development program with a clear path to future military utility.
Assess existing test facilities and capabilities and highlight potential gaps which would impact system development.
Identify technology gaps and recommend R&D efforts to address those gaps including roadmaps and expected maturity timelines.
