MINUTEMAN III TEST LAUNCH SHOWCASES READINESS OF U.S. NUCLEAR FORCE’S SAFE, EFFECTIVE DETERRENT
By Air Force Global Strike Command Public Affairs / Published August 11, 2021
BARKSDALE AIR FORCE BASE, La. --
Air Force Global Strike Command Airmen launched an unarmed Minuteman III intercontinental ballistic missile equipped with a test re-entry vehicle from Vandenberg Space Force Base, California Aug. 11 at 12:53 a.m. Pacific Time to demonstrate the readiness of U.S. nuclear forces and provide confidence in the lethality and effectiveness of the nation’s nuclear deterrent.
This launch involved a Hi Fidelity Joint Test Assembly re-entry vehicle that detonated conventional (i.e. non-nuclear) explosives prior to hitting the surface of the water approximately 4,200 miles downrange near Kwajalein Atoll in the Marshall Islands. These test launches verify the accuracy and reliability of the ICBM weapon system, providing valuable data to ensure a continued safe, secure and effective nuclear deterrent.
Finally launched after several months of delays.

NASA Sounding Rocket Flight EVE 36.353 2.5 Minute HighlightsThis rocket launch on 2021-09-09 from White Sands Missile Range carried a copy of the Solar Dynamics Observatory Extreme Ultraviolet Variability Experiment (SDO/EVE) instrument. SDO/EVE has been in geosynchronous orbit since 2010; it's a flagship NASA solar mission staring at the Sun 24/7. That causes the instruments to degrade over time, so every ~2 years we fly this copy of the instrument that otherwise stays in our clean lab in order to see how intense the Sun _should_ be at each wavelength of extreme ultraviolet light between ~6-106 nm. We compare that with the SDO/EVE instrument on orbit and can correct the data to remove the degradation.
And since we're going up anyway, we put a whole bunch of other instruments in the rocket payload. Several of those were literally built at home, in garages, and finishing touches in our professional lab at the University of Colorado Boulder Laboratory for Atmospheric and Space Physics. This flight included instruments called SPA-X-ray Sensor (XRS), SPA-Occultation Wave Limb Sounder (OWLS), and Dual-zone Aperture X-ray Solar Spectrometer (DAXSS).
This ~2.5-minute cut shows most of the interesting stuff that happened during this 16-minute flight, plus some fun things when the team arrived to recover it after landing, and finally what the Sun looked like in one of the extreme ultraviolet wavelengths we observed (taken from SDO / Atmospheric Imaging Assembly) and a snapshot of the EVE data from the flight.

22:07:30 UTC, actually.
I meant that, it was a typo. Thanks for the correction btw.

Here's a very nice document from the US Missile Defense Agency (MDA) giving GBI, SM and THAAD missile intercept tests since 1999, as well as the reasons why some of the tests failed. A sobering statistic is that since 2001, the intercept success rate is only 80%.

That's because my brain is stuck in September. Thanks, edited

UP Aerospace successfully launched a SpaceLoft-XL suborbital rocket (serial number SL-16) on August 11 carrying the ReDX-1 mission for the Los Alamos National Laboratory.
Anyone know what ReDX is the acronym for? All articles only state ReDX-1 as the payload.
Thanks.

I don't know, but ReDX could stand for Responsiveness Demonstration Experiment.

Turns out they were hypersonic technology test flights!
Navy and Army Demonstrate Advanced Hypersonic TechnologiesThe Navy Strategic Systems Programs (SSP) and the Army Hypersonic Program Office (AHPO) successfully conducted a High Operational Tempo for Hypersonics flight campaign on October 20, 2021.
This flight campaign was executed by Sandia National Laboratories (SNL) from the National Aeronautics and Space Administration (NASA) Wallops Flight Facility. This test will be used to inform the development of the Navy’s Conventional Prompt Strike (CPS) and the Army’s Long Range Hypersonic Weapon (LRHW) offensive hypersonic strike capability.
This test demonstrated advanced hypersonic technologies, capabilities, and prototype systems in a realistic operating environment. Three precision sounding rocket launches were conducted containing hypersonic experiments from partners, including CPS, AHPO, the Joint Hypersonic Transition Office, SNL, Johns Hopkins University/Applied Physics Laboratory, MITRE, Oak Ridge National Laboratory, and several defense contractors.
These are Terrier-Improved Malemute sounding rockets, if I'm not mistaken?
