A NASA Terrier-Black Brant IX suborbital sounding rocket launched the Diffuse X-rays from the Local galaxy, or DXL, mission from the Poker Flat Research Range (PFRR) in Alaska, on 19 January 2018. The DXL investigation aims to study the sources of X-rays that hurtle towards Earth from elsewhere in the Milky Way galaxy.

Three Terrier-Improved Orion sounding rockets were launched from Poker Flat Research Range, AK on January 26, 2018. The purpose of the Super Soaker missions was to study the time dependent neutral chemistry and transport of water in the upper atmosphere and to determine the resultant impact on the local temperature and Polar Mesospheric Cloud (PMC) formation.

More details are provided in NASA's "Rocket Report" of Q4:

41.119, 41.120 & 41.122 CE Azeem - SuperSoaker
Three Terrier-Orion sounding rockets will be launched from Poker Flat Research Range in Alaska in
January 2018, as part of the Transport, Chemistry, and Energetics of Water in the Mesosphere and Lower
Thermosphere and Implications for Polar Mesospheric Cloud Occurrence mission, also referred to as the
Super Soaker mission.

Polar Mesospheric Clouds (PMC), also called Noctilucent Clouds (NLC) are thin ice clouds that form at
atlitudes of near 85 km at high latitudes in the summer. For these clouds to form, three constituents are
needed: cold temperatures, water vapor, and particles for condensation. The sounding rocket mission
will study the dynamics of the Mesosphere and Lower Thermosphere (MLT) regions and specifically how
release of water in this region impacts local temperature and PMC formation.
The first two Super Soaker rockets, launched 30-minutes apart, will release vapor trails and measure the
background winds. The trails will be tracked optically to measure any changes to the winds and allow
observation of how the atmosphere responds dynamically to the injection of water. The third rocket,
launched 30-seonds after the second, will disperse a large payload of water in the MLT. Additionally the
evolution of temperature and any ice particles in the MLT before, during and after the water release will be
studied using a lidar. An Advanced Mesospheric Temperature Mapper (AMTM) instrument will be deployed
to image the upper mesosphere (~87 km) before, during and after the water release to provide quantitative
information on any dynamics/wave activity and changes in mesospheric temperature. The sky will be
continuously imaged throughout the experiment at a variety of visible and IR wavelengths to quantify the
formation and evolution of any mesospheric clouds formed as a result of the water release. The launch
date, January 2018, avoids the summertime PMC season and ensures clear mesospheric air before the
release.

Israeli test of Arrow-3 missile defense system a 'success'
After 2 canceled trials in as many months due to technical malfunctions, Israel successfully launches exo-atmospheric anti-missile system, paving way for giant experiment of upgraded version in the US.
...
With the successes registered on a simulated target, the experiment will enable the Defense Ministry to carry out a series of similar but larger scale interception tests above giant land masses in unpopulated areas in Alaska in the US later in the year. Due to insufficient landmass, Israel is restricted in the scope of its experiments.

“If there was a real target there it would have hit it,” explained an official in the Defense Ministry. “We wanted to focus on the requirements for the approval of experiments in Alaska. We didn’t incorporate into it a genuine target in order to stick to the deadline. Each weapon system has been proven in this experiment.”
...

The article also has some video of the launch and early ascent embeded in the body.  Overview of the info from the article was that it was a test of an upgraded/improved Arrow-3 interceptor which included the full system but was against a simulated target.  It was the final shakedown test in Israel before moving testing to Kodiak, Alaska currently planned for later this year.  This test came after 2 previous test launches had been called off over the past 2 months due to problems outside the interceptor (once in the target missile and once in the data transfer of the C4I system).
Shouldn't reality posts be in "Advanced concepts"?  --Nomadd

Vladimir Putin threatens US arms race with new missiles announcement

Quote
Russian president says Moscow has developed new line of nuclear-capable weapons that can breach US defences

Quote
Vladimir Putin said on Thursday that Russia had developed and was testing a new line of strategic, nuclear-capable weapons that would be able to outmanoeuvre US antiballistic missile defences, suggesting a new arms race between Moscow and the west.

Speaking in a nationally televised address to Russia’s political elite, the president showed both video and animation of Russian ICBMs, cruise missiles, and other weapons that he said Russia had developed as a result of the US pulling out of the 1972 antiballistic missile treaty signed with the Soviet Union.

“You didn’t listen to our country then,” Putin said during the speech, where he said that some of the weapons were already being tested. “Listen to us now.”

The remarks came during a state of the union speech heavy on economic promises for the Russian people and sabre-rattling against the US in a presentation widely viewed as Putin’s first stump speech for Russian elections, set for 18 March. He is expected to win a fourth term as president.

Anatoly Zak analyses the Sarmat ICBM.

Quote
The development of the Sarmat missile reportedly started between 2009 and 2011 and coincided with the deterioration of Russia's relations with the West. The decision to build the "new-generation Satan" was not without controversy, because large liquid-propellant missiles were long considered obsolete. For example, the United States long abandoned liquid propellant in its strategic arsenal in favor of compact solid-propellant missiles.

The Sarmat program also encountered various problems with the rocket itself and with its manufacturing base, which apparently delayed its introduction into the armaments years behind the originally planned date of 2016. First throw tests in Plesetsk, which only saw the ejection of a dummy missile from its silo, took place around December 2017, or at least a year later than publicly promised. Around the same time, the first launch of the flight worthy missile was promised before the end of 2018.

Regarding the Russian announcement - specifically the nuclear-powered cruise missile - could that technology be adapted for space applications?

I recall reading that the US had a Project Pluto (SLAM missile), and also a "Big Stick" proposal (GeneralDynamics/Convair), but these were open-cycle reactors which would have generated radioactive exhaust.

The Russian long-range nuclear-powered cruise missile was announced alongside a long-range nuclear-powered torpedo, and I presume that it could be the same power source being used for both. That might possibly be a closed-cycle reactor of small size with enough power output for propulsion. Or could even an RTG supply the necessary power?

If it was a small closed-cycle nuclear reactor which could power an electric turbofan or torpedo propeller, then could it be used to usefully power a VASMIR or ion-engine?

That’s an interesting suggestion. I looked through the official translation of President Putin’s speech and I don’t think I saw one mention of space.

He does mention space, right at the beginning.

"It is at such turning points that Russia has proven, time and again, its ability to develop and renew itself, discover new territories, build cities, conquer space and make major discoveries."

Sad that nuclear missiles are getting all the glory though.

Sorry missed that.

They are also getting all the budget, judging by the Russian space budget going forward.

Russia Halts Years of Work On Ballistic Missile To Pay For Hypersonic Weapons

Quote
Just weeks after Russian President Vladimir Putin mentioned it in a provocative speech, Russia has reportedly decided shelve development of its RS-26 Rubezh intercontinental ballistic missile system and focus on fielding the nuclear-armed Avangard hypersonic boost glide vehicle using other designs. The decision suggests the Kremlin may feel the hypersonic weapon is more valuable than the missile carrying it, but also raises questions about whether the country has the necessary funds to support its broader strategic plans.

On March 22, 2018, Russian state-run news outlet TASS reported that development of the RS-26 was no longer a feature of the state armament plan for 2018 to 2027. In an annual state of the union address on March 1, 2018, Putin had said that the road-mobile Rubezh would be the primary launch vehicle for Avangard. The country had previously used the latter name to refer to the entire development program, including the intercontinental ballistic missile (ICBM) component. 

“The Avangard was included in the [state armament plan] program’s final version as more essential to ensure the country’s defense capability,” the source said, according to TASS. “All the work on the Rubezh and the Barguzin [rail-mobile ICBM] was put on hold until the end of 2027. A decision on the work’s resumption will be made after the current armament program is fulfilled.”

I couldn't watch that video as its region restricted, but I could watch this one. He also had a launch on 30 January 2014 where the parachute opened with a lot of rips causing a hard landing. We never actually see Mike in the cabin during the flight.
