Virgin Orbit announces first launch attempt. On Wednesday, the company that has been developing LauncherOne for most of the last decade said it is ready to make a launch attempt. The rocket, which is dropped from a modified 747 aircraft, will not carry a customer's payload. The mission, which is being classified as a "launch demo," is set to take place between 10am and 2pm PT (17:00-21:00 UTC) on Sunday.

Now that's setting expectations … "Our goal is to safely learn as much as possible and prove out the LauncherOne system we've worked so hard to design, build, test and operate," the company said. "We'll continue the mission for as long as we can. The longer LauncherOne flies, the more data we'll be able to collect. Should we defy the historical odds and become one of those exceedingly rare teams to complete a mission on first attempt, we will deploy a test payload into an orbit, take our data, and then quickly de-orbit so as not to clutter the heavens."

Relativity nabs SpaceX launch and production VP. Relativity Space, a California-based company pushing hard toward the inaugural flight of its Terran 1 rocket by the end of 2021, has hired a senior launch official from SpaceX. Zach Dunn, formerly senior vice president of production and launch at SpaceX, will become vice president of factory development at Relativity, Ars reports.

Factory of the future … The well-capitalized startup recently announced plans to build a large 3D-printing factory in Long Beach, California. Dunn's first job will be to oversee the development of this facility, said Tim Ellis, co-founder of Relativity. "We really are looking to develop the factory of the future, as its own product," Ellis said. Dunn has a storied history at SpaceX, playing a key role in the development of the Falcon 1 and Falcon 9 rockets.

SpaceX rideshare drives launch prices down. The Falcon 9 rideshare program the company started in August is putting downward pressure on the cost of launching small satellites, SpaceNews reports. "SpaceX is offering pricing that previously wasn't really seen," said Mike Safyan, vice president of launch at Planet, an Earth-imaging company with more than 150 small satellites in orbit. Planet announced last week that it will launch six SkySat satellites as rideshare payloads on future Starlink missions.

A hyper-competitive program … SpaceX advertises a base price of $1 million for launching up to 200 kilograms and $5,000 extra per kilogram. The rideshare program is "incredibly competitive," Safyan told SpaceNews. He called it "one of the more significant programs for the smallsat industry especially because of the pricing, the reliability and the number of orbits." The business case for smallsat launchers already seemed pretty difficult to close. This doesn't help. (submitted by Ken the Bin, JohnCarter17, and platykurtic)

Momentus signs additional contracts. Speaking of making life difficult for smallsat launch providers, this week Momentus Space announced contracts with video-streaming company Sen, satellite manufacturer Alba Orbital, and Polish nanosatellite startup SatRevolution. Momentus is developing vehicles to provide in-space propulsion for small satellites, SpaceNews reports.

A ride after your ride … One of the key criticisms of rideshare for small satellites is that launching a bundle of different satellites does not allow customers to enter desired orbits. However, a service like Momentus can take a small satellite deployed on a rideshare launch and move it where a company wants it to go. It's no surprise that several of Momentus' customers plan to launch on future Falcon 9 rideshare missions. (submitted by JohnCarter17).

Vega C launch debut likely delayed until 2021. Italian rocket builder Avio will keep a team of launch personnel in French Guiana from May through August in the hopes of completing three Vega launches this year, notwithstanding coronavirus-related slowdowns, SpaceNews reports. Work continues on the upgraded Vega C, but it probably will not fly before next year, Avio chief executive Giulio Ranzo said.

Workers back to French Guiana launch site … Vega is scheduled for a return-to-flight mission in mid-June that will be the rocket's first launch in 11 months. The rocket will carry 52 small satellites to low Earth orbit in a dedicated rideshare mission. After a nearly two-month pandemic shutdown, Avio sent a team of more than 60 people to the Guiana Space Center on May 11 to begin work. The team is subject to a 14-day quarantine.

Skyrora completes static-fire test of its rocket. During the ground test at a mobile launch complex at Kildermorie Estate in North Scotland earlier this month, Skyrora's launch vehicle Skylark L performed all actions of a launch while being held down, the company said. "This is the first time a launch vehicle of this magnitude has been tested in the UK for many years," said Jack-James Marlow, who led the test. "The vehicle is now ready for flight and we are one step closer to putting the UK back into space."

Aiming for an early 2021 launch … Skylark L is a bi-liquid-propellent, suborbital launch vehicle. Building up to the static-fire test, the rocket engine itself had gone through three hot-fire tests before integration into the vehicle. The company plans to use its own Ecosene fuel, an equivalent kerosene fuel made from un-recyclable plastic waste. Skyrora intends to start launching the Skylark L next spring and move to orbital flights by 2023. (submitted by Ken the Bin)

NASA got a stunning value in the Falcon 9. With the first flight of humans atop a Falcon 9 rocket coming as early as next Wednesday, Ars takes a look back at the origin's of NASA's commercial crew and cargo programs. As part of its initial investment of $396 million into SpaceX, NASA got development of the Cargo Dragon, Falcon 9, and a launch site at Cape Canaveral.

A cost of 50 times more … At the same time, NASA was developing the Ares I rocket to fly crew into low Earth orbit. Independent estimates placed the cost of Ares I at about $20 billion. President Obama ultimately canceled the Ares I, projected to have a similar lift capacity to the modern Falcon 9 booster, because it was behind schedule and over budget. The agency, in turn, got a bargain.

Ariane 6 inaugural launch likely delayed until 2021. The first launch of Europe's next-generation large rocket appears all but certain to slip into 2021 because of development delays the European Space Agency and the rocket's manufacturer ArianeGroup attribute to the coronavirus pandemic, SpaceNews reports. Before the crisis, Arianespace had planned on Ariane 6 making its debut between October and December.

More clarity will come … "ESA is working intensely, and very closely with all actors involved, industry and CNES, to stabilize and consolidate the planning," Daniel Neuenschwander, the director of space transportation at the European Space Agency, told the publication. "Today we are daily addressing the preliminary impacts and preparing to return to a stable level of activity. We will fully consolidate the planning and assess the full impact of COVID-19 on Ariane 6 once we have more clarity on how the European economy will be able to function in the coming months."

SpaceX delays next Starlink mission. Citing a tropical storm in the downrange booster recovery zone, SpaceX said Monday that a launch of up to 60 more Starlink Internet satellites will be delayed, Spaceflight Now reports. The mission had previously been planned this for week from Cape Canaveral and will now be delayed until after the launch of the company's first crewed flight.

Testing limits of reuse … The reusable first stage slated for launch on this Starlink mission has flown four times before. SpaceX hopes to recover it again for inspections and more potential flights. It will provide critical data as the company seeks to test out the limit on flights that a Falcon 9 booster can achieve without major refurbishment. (submitted by Ken the Bin and JohnCarter17)

Atlas V rocket successfully launches. As it does, United Launch Alliance's Atlas V booster made a smooth flight to orbit on Sunday from Cape Canaveral Air Force Station. It carried the X-37B space plane into orbit for the Space Force for what is likely to be a two-year mission.

Some sweet pics … This launch was delayed from Saturday morning due to poor weather over the Florida-based spaceport. Clearer skies on Sunday meant that images captured by remote cameras set up by Ben Cooper, who shoots photos for United Launch Alliance, benefited from clear skies and brilliant sunlight. If you need some rocket eye candy, it's worth checking out.

Japan's H-2B rocket makes final flight. The booster conducted its final mission Thursday, launching the ninth and last H-2 Transfer Vehicle spacecraft to the International Space Station, Read More – Source
