Roscosmos Director General Dmitry Rogozin said Russia will no longer sell rocket engines to U.S. companies, dealing a potentially fatal blow to Northrop Grumman’s Antares rocket. The decision was made in retaliation for U.S. sanctions over Russia’s invasion of Ukraine last week.

The Friday launch of 36 OneWeb broadband satellites aboard a Soyuz rocket from Baikonur Cosmodrome is officially canceled as the London-based company refused demands from the Russian government amid growing international tensions over the Russian invasion of Ukraine.

“The Board of OneWeb has voted to suspend all launches from Baikonur,” the company said in a one-sentence statement.

In what is likely the first hostage drama involving communication satellites, the head of the Russian space program has demanded that the British government divest its shares in OneWeb and that the broadband satellite operator not provide services to foreign militaries in order to launch a new batch of spacecraft. The move comes amid growing tensions over Russia’s invasion of Ukraine and sanctions imposed on the country by western nations.

Roscosmos Director General Dmitry Rogozin tweeted that unless these demands are met, Russia will refuse to launch 36 OneWeb satellites that sit atop a Soyuz-2.1b rocket currently on the launch pad at the Baikonur Cosmodrome in Kazakhstan. The launch is scheduled for Saturday morning Moscow time.

The United States reclaimed the top spot in launches from China last year as NASA astronauts flew into orbit from American soil for the first time in nearly nine years, SpaceX deployed the world’s first satellite mega-constellation with reused rockets, and two new launchers debuted with less than stellar results.

American companies conducted 44 launches in 2020, with 40 successes and four failures. Bryce Tech reports that U.S. companies accounted for 32 of the 41 commercial launches conducted last year. The majority of those flights were conducted by SpaceX, which launched 25 orbital missions.

China came in second with a record of 35 successful launches and four failures. The 39 launch attempts tied that nation’s previous record for flights during a calendar year.

Let’s take a closer look at what U.S. companies achieved last year.

SpaceX dominated, China surged and Russia had another clean sheet as American astronauts flew from U.S. soil again in a year of firsts.

Despite the COVID-19 pandemic, 2020 was a very busy launch year with a number of firsts in both human and robotic exploration. A total of 114 orbital launches were attempted, with 104 successes and 10 failures. It was the same number of launches that were conducted in 2018, with that year seeing 111 successes, two failures and one partial failure.

Technical issues related to related to “the igniter and booster capabilities” with Blue Origin’s BE-4 engine could delay the maiden flight of United Launch Alliance’s (ULA) new Vulcan Centaur booster scheduled for late this year, according to a new report from the Government Accountability Office (GAO).

Until the advent of the reusable Falcon 9, most first stages of rockets fell into the ocean, on the lightly populated steppes of Kazakhstan (Russian launches from Baikonur), or crashed beside and even into rural villages, throwing up huge clouds of toxic propellants in the process (Chinese launches).

Russia recently marked the 25th anniversary of the entry of the Proton rocket into the international commercial marketplace. On April 8, 1996, a Proton-K booster with a DM3 upper stage launched the Astra 1F geosynchronous communications satellite built by U.S.-based Hughes for Luxembourg’s SES from Baikonur Cosmodrome in Kazakhstan.

VANDENBERG AIR FORCE BASE, Calif., April 26, 2021 (ULA PR) – A United Launch Alliance (ULA) Delta IV Heavy launch vehicle carrying the NROL-82 mission for the National Reconnaissance Office (NRO) lifted off from Space Launch Complex-6 on April 26 at 1:47 p.m. PDT. To date ULA has launched 143 times with 100 percent mission success.

The month of April is concluding with a string of launches from Russia, the United States, China and South America. Things kicked off on Friday with SpaceX’s launch of Crew-2 to the International Space Station (ISS). On Sunday, a Russian Soyuz rocket launched 36 OneWeb satellite broadband spacecraft from the Vostochny Cosmodrome in Russia’s Far East.

One of the final United Launch Alliance Delta IV Heavy rockets is scheduled to launch from Vandenberg Air Force Base on Monday afternoon. That flight will be followed by the fifth launch of China’s Long March 6 booster. Launches by Europe’s Vega and SpaceX’s Falcon 9 rockets are scheduled over the next two days.

China will close out the month on Thursday by launching Tianhe-1 core module for that nation’s first permanent space station aboard a Long March 5B booster.

The full schedule for the week is below.
