Rocket Lab is preparing for its twentieth launch of an Electron rocket, named “Running Out of Toes,” carrying two Earth-observation satellites for BlackSky’s global monitoring constellation. The company is also aiming to recover an Electron first stage for the second time after a soft splashdown in the Māhia Recovery Zone in the Pacific Ocean.
This will be the first of four dedicated missions scheduled for this year for BlackSky, a real-time geospatial intelligence and global monitoring services company, working in tandem with Spaceflight Inc providing mission management and payload integration services. The launch is currently targeted for 10:00 UTC from Rocket Lab Launch Complex 1A on the Māhia Peninsula in New Zealand. The launch window is open for two hours and five minutes. ....

ULA completes Delta IV Heavy pad upgrades ahead of NROL-82 mission
April 19, 2021
United Launch Alliance (ULA) has recently made pad upgrades to Space Launch Complex-6 (SLC-6) at Vandenberg Air Force Base, California, ahead of the upcoming Delta IV Heavy launch of the NROL-82 mission for the National Reconnaissance Office scheduled for April 26 at 15:39 EDT / 19:39 UTC.
The previous Delta IV Heavy mission, NROL-44 from SLC-37B at Cape Canaveral, Florida, was plagued by numerous issues, scrubs, and aborts that uncovered issues with the launch pad and its facilities.
After rolling to the pad in November 2019, the flight reached its first launch attempt on August 27, 2020. This attempt ended without fueling of the vehicle after a heater and pneumatic issue forced controllers to scrub the launch. ....

With the completion of another single-engine RS-25 development test, Aerojet Rocketdyne is now refurbishing five engines at the Stennis Space Center in Mississippi for their next use. After the second test firing of the Retrofit 2 series in the A-1 Test Stand on April 6, development engine 0528 is going through a streamlined refurbishment prior to its next firing as a part of the production restart Retrofit 2 test series.
In parallel, the four RS-25 engines installed on the first Space Launch System (SLS) Core Stage in the nearby B Test Stand are being taken through a longer refurbishment checklist for flight engine hardware. The next planned ignition for those Core Stage engines is for the first SLS launch on the Artemis 1 mission to send an Orion spacecraft to lunar orbit. ....
