Russia tests perspective armament for Topol ICBM
Quote
On December 26, 2017, a combat team of the Strategic Missile Force test-fired an RS-12M Topol intercontinental ballistic missile from the Kapustin Yar state central combined arms training range in the Astrakhan Region,"

On December 26, 2017 the Strategic Rocket Forces conducted a successful launch of a Topol/SS-25 missile from the Kapustin Yar test site. The test was used "to collect experimental data that will be used to develop advanced missile defense countermeasures."
Previous Topol launch from Kapustin Yar to Sary-Shagan took place in September 2017.

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.

Supersoaker test.

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).
