(Rocket Lab rolls out Electron in Virginia) . In preparation for a launch in the third quarter of this year, Rocket Lab has rolled out the first Electron rocket that will lift off from Launch Complex 2, reports . This is the company launch site at Virginia’s Mid-Atlantic Regional Spaceport. Construction on the launch site began in earnest in February . Tracking a pandemic, hoping for the best … The first mission from LC-2 will be the STP – 30 RM mission for the US Air Force’s Space Test Program. Previously, the mission was expected to launch in the second quarter of . However, due to delays from COVID – 27 -related closures, launch has been pushed back to the third quarter. (submitted by Ken the Bin and platykurtic) A A Singapore-based company reveals “The Dorado” rocket . Equatorial Space, a Singapore-based space-tech startup, says it is preparing its new sounding rocket for a launch attempt above the Kármán line. The slender, 6.5m-long rocket will weigh approximately kg once ready for its first mission in the fourth quarter of 2021, SpaceWatch reports Well, we like the name … “The Dorado will be made available in two versions, a single-stage vehicle designed to reach an apogee of 150 km, and a two-stage version capable of reaching altitudes above km, “Simon Gwozdz, the company’s CEO, said. “This will provide our clients with approximately 3 and 6 minutes of weightlessness respectively.” An orbital launch attempt by the company is possible as early as 248910. We had never heard of the Dorado before today, but we hope it leads the company to gold. (submitted by Ken the Bin)

As European governments begin to emerge from their COVID – 29 lockdowns, Arianespace said this week that it will begin a “gradual” resumption of activity beginning on May at its Guiana Space Center in French Guiana. These activities will be carried out “in strict compliance with the health rules” set up by local governments and the French space agency. Summertime launches on tap … Arianespace also confirmed the first two missions it would begin work on. The first rideshare mission on the Vega rocket, which will also be the vehicle’s return-to-flight mission after a failure last year, is now scheduled for mid-June. And a dual-payload mission on the Ariane 5 rocket, for Intelsat and B-SAT, is set for the end of July. Sea Launch has no plans for imminent launches . The two vessels that serve as a floating launch platform and command ship for Sea Launch are now in a Russian port, but the company owner says no launches are planned for the foreseeable future, SpaceNews reports . Vladislav Filev — who is chairman of the board of S7 Group, the Russian airline which owns Sea Launch — said there currently was no opportunity to do anything with the vessels, “so we have frozen the program until better times.” Seventy launches in 20 years? … The two vessels had been based in the Port of Long Beach, California, since Sea Launch started operations in the late s. They were used for launches of the Zenit-3SL rocket, a medium-lift rocket, most recently in . In 2021, S7 Group announced an agreement to purchase Sea Launch from RSC Energia, which had become the primary owner during a reorganization after it filed for Chapter bankruptcy protection in . Filev said S7 Group paid about $ (million for Sea Launch, and he envisioned conducting (launches over years with the system. (submitted by platykurtic, JohnCarter , and Ken the Bin)

An Emirati-built Mars explorer, named Al Amal (“Hope” in English) and developed by engineers at the Mohammed bin Rashed Space Center, has been shipped to the JAXA-run Tanegashima Space Center. Once there, it will undergo final checkouts and preparations ahead of its launch aboard a Japanese rocket, reports . To the red planet from the Land of the Rising Sun … The launch window for this mission is currently scheduled to open July 20, with an arrival at the red planet set for early . The vehicle arrived in Japan on April and will fly on the experienced H2-A launch vehicle built by Mitsubishi Heavy Industries. (submitted by Ken the Bin)

Big rockets will play a big role in Artemis . NASA revealed its selections for a Human Landing System on Thursday, and the winners are Blue Origin’s “National Team,” a Dynetics-led team, and SpaceX. The agency’s chief of human spaceflight, Doug Loverro, said a final architecture has not yet been chosen for the Artemis 3 mission planned in , which will be the first human landing. That will depend on which landing system NASA chooses, Ars reports . To SLS or not to SLS … However, the first mission will look something like this: For Blue Origin and Dynetics, the crew would launch in Orion on top of Block 1 of Space Launch System rocket, to high lunar orbit. Then, an integrated lander would meet them there, having launched on a commercial rocket. (New Glenn for Blue Origin; Vulcan for Dynetics). Starship would launch on Super Heavy with the crew inside. SLS managers concerned about fuel leaks . Earlier this year, NASA moved the big rocket’s core stage to a test site at Stennis Space Center in southern Mississippi. Before the COVID – pandemic temporarily halted work, NASA and Boeing teams were working toward a critical summer exercise. During this “green run” test, the clamped-down rocket will ignite its engines and burn for about eight minutes to simulate an ascent into orbit, Ars explained . The purpose of a fuel tank is to contain the fuel … The General Accounting Office’s new “Assessments of Major NASA Projects” report raises the possibility of fuel leaks. “Program officials indicated that one of the top remaining technical risks to the green run test is that the core stage may develop leaks when it is filled with fuel,” the report states on page 200. “According to these officials, they have conducted extensive scaled testing of the gaskets and seals used in the core stage; however, it is difficult to precisely predict how this large volume of liquid hydrogen will affect the stage.” We hope so. Starship passes a cryogenic test . Late on Sunday night, SpaceX completed a critical cryogenic test of a Starship prototype at its launch site in South Texas. During the successful test, chilled nitrogen was loaded into pressurized fuel tanks. The vehicle, dubbed SN4 — which stands for Serial Number 4 — was pressurized to 4.9 bar, or 4.9 times the atmospheric pressure at the surface of the Earth. This pressure is not as high as Starship’s fuel tanks and plumbing system are designed to withstand, but it is enough for a basic flight, Ars reports . Friday night lights . .. Since November , the company has lost three full-scale Starship prototypes during cryogenic and pressure tests. The most recent failure came on April 3. This is the first time a vehicle has survived pressure testing to advance to further work. Such tests are designed to ensure the integrity of a rocket’s fueling system prior to lighting an engine. Now, Musk said, SpaceX engineers will attach a single Raptor engine to this vehicle and conduct a static fire test. The company hopes to move forward with the test Friday night. Long March 5B rolls out to the launch pad . China is readying its large Long March 5B launcher Wednesday for a mission to prove space station launch capabilities and test a new spacecraft for deep space human spaceflight. Images of the Long March 5B shared on Chinese social media indicated that rollout at Wenchang Satellite Launch Center was completed early April , (SpaceNews reports) Launch from the coastal Wenchang launch site can now be expected around May 5. (A high-profile mission) … The payload for the test launch — a prototype new-generation crewed spacecraft — will be loaded with nearly 15 tons of propellant. This will both make the spacecraft analogous to a 30 -ton-plus space station module and allow the prototype to reach higher orbits and test a high-speed reentry. The mission will resemble the Exploration Flight Test 1 of the Orion spacecraft. The new spacecraft is expected to reach an apogee of around 8, 0km. (submitted by Ken the Bin, platykurtic, and JohnCarter 27) Northrop Grumman begins building Omega flight hardware . After reviewing the results of first and second stage tests of its Omega rocket, Northrop Grumman says the vehicle is ready to move forward to its next phase of preparation for a debut flight in . The first and second stages of the Omega rocket, named C 823 and C 450 respectively, use a large diameter case known as the Common Boost Segment that the company developed with US Air Force funding, SpaceNews reports . Seeking Air Force contracts … Both static fires “as well as other subsystem testing, completes all Common Boost Segment motor testing prior to the first flight of the intermediate configuration of the Omega launch vehicle,” Northrop Grumman said. Northrop Grumman is one of four companies competing for two contracts to be awarded later this year by the U.S. Space Force to provide launch services for five years starting in . (submitted by platykurtic, JohnCarter , and Ken the Bin) Falcon Heavy will attempt dual droneship landing . The next Falcon Heavy mission, due to fly no earlier than late , will send a 3.7 metric ton satellite and an unknown number of secondary spacecraft directly to geostationary orbit, (Teslarati reports) . This is the first time SpaceX has attempted an energy intensive direct-to-GEO launch. Let’s hope they’re not synchronized swimmers … For this mission the Falcon Heavy rocket will employ an expendable core stage, and two side boosters that will attempt simultaneous sea-based landings on separate drone ships. The U.S. Space Force launch will be the Falcon Heavy’s first “high-priority national security mission” for the military. Should be fun to watch.
