A Rokot booster placed a Russian military satellite into orbit on Friday on its last mission for the Russian Ministry of Defence.
The booster lifted off from the Plesetsk Cosmodrome in northern Russia and successfully placed the Geo-IK-2 No.13 military mapping satellite into orbit.
“The Rokot rocket’s launch was the last one under the Defense Ministry’s program. Another one is due for Roscosmos. The rocket’s operation is over because there are plans for using an advanced type of this vehicle,” Major-General Nikolai Nestechuk told Tass.
Nestechuk did not specify what advanced booster will be used in Rokot’s place.
Rokots are an adaptation of retired SS-19 Stiletto intercontinental ballistic missiles. The booster has launched 33 times with 30 successes, two failures and one partial failure since 1990.
Rokot was formerly marketed as a commercial launcher by Eurockot Launch Services, a joint venture of Russia’s Khrunichev and ArianeGroup. However, that program ended as Russia decided to phase out the booster.
The Eurockot website says the company’s activities are “under redefinition. We will start accepting launch requests in the near future.”
PLESETSK, Russia (Roscosmos PR) — Today, on July 30, 2019, at 05:56 UTC the Russian Aerospace Forces crew successfully launched the Soyuz-2.1a carrier rocket with the Russian communications satellite Meridian onboard.
The launch and injection into orbit went as planned. In three minutes
after the launch the Titov Main Test and Space Systems Control Centre
automated complex acquired the Soyuz 2.1a rocket track.
At the designated time, the Meridian spacecraft was injected into the
final orbit and acquired by the ground control means of the Russian
Aerospace Forces. The satellite maintains stable telemetry connection,
all the onboard systems function as planned.
The Meridian satellite is meant to provide communication between the
sea vessels, ice patrol aircraft in the Northern Sea Route district with
the coastal and ground stations, as well as to develop the satellite
communication station network in the Northern Siberia and the Far East
in order to support Russia’s economic development.
Поздравляем командование Космических войск, боевой расчёт космодрома Плесецк, коллективы РКЦ “Прогресс” (Самара), НПО имени С.А.Лавочкина (Химки) и ИСС имени академика М.Ф.Решетнёва (Железногорск) с успешным запуском КА ГЛОНАСС! Молния вам не помеха pic.twitter.com/1cmlZ4hD1g

The Soyuz booster successfully orbited a GLONASS-M navigation satellite from the Plesetsk Cosmodrome in northern Russia.
The Saturn V taking the Apollo 12 to the moon in 1969 was also struck by lightning after launch. The rocket was fine; the guidance system was deep inside the rocket. However, the electronics in the spacecraft were knocked out. Flight controller John Aaron said to flip the SCE switch to AUX. When Alan Bean did so, the spacecraft came back online.
Mission Control fretted about whether to send the crew to the moon. Everything seemed fine aboard the spacecraft, but there was one crucial system they couldn’t check: the parachutes. Controllers realized that in the unlikely event the lightning strike had fried the parachute deployment system, the crew would die anyway. Might as well send them to the moon.
If you are among the millions of space enthusiasts who have been losing sleep over why Russia’s new Angara rocket hasn’t flown in more than four years, be prepared to snooze soundly again.
Ruetersreports that engineers have found a flaw in the engine of the Angara A5 booster that could cause it to explode in flight.
The issue with the Angara A5 was brought to attention by scientists at rocket engine manufacturer Energomash in a paper ahead of a space conference later this month.
The paper, reported by RIA news agency on Friday and published online, said the engines of the Angara A5 could produce low frequency oscillations that could ultimately destroy the rocket.
A special valve had been fitted to mitigate the issue, but in some cases the oscillations continued, it said. Energomash did not immediately reply to a request for comment.
The Angara A5 rocket is the most powerful of a family of boosters designed to replace the Proton and other launch vehicles currently in the Russian arsenal. The Angara series is based around a common first stage core with additional strap-on stages.
The Reuters story says that Russian President Vladimir Putin is eager to see the rocket start launching more frequently because it is vital to the nation’s national defense.
The Angara 1.2PP rocket made the maiden flight test of the series on July 9, 2014. The booster flew a suborbital mission carrying a mass simulator from the Plesetsk Cosmodrome in Northern Russia.
Angara A5 flew was launched from Plesetsk five months later on Dec. 23, 2014. Using a Briz-M upper stage, the booster placed a mass simulator into geosynchronous orbit.
The Wikipedia page for Angara lists two launches of the Angara A1.2 and one flight of Angara A5P for 2019. There is one Angara A1.2 flight listed for 2020. However, it is not clear whether this schedule is still valid; it came from a schedule compiled in late 2017.
The United States said this week that a Russian satellite launched last year is exhibiting “very abnormal behavior” in orbit, suggesting that it is a weapons system rather than a “space apparatus inspector” as claimed by the Russian Ministry of Defense.
“In October of last year the Russian Ministry of Defense deployed a space object they claimed was a ‘space apparatus inspector,'” said Yleem D.S. Poblete, assistant secretary at the U.S. Bureau of Arms Control, Verification and Compliance. “But its behavior on-orbit was inconsistent with anything seen before from on-orbit inspection or space situational awareness capabilities, including other Russian inspection satellite activities.”
The world’s launch providers were extremely busy in the first half of 2018, with China and the United States battling for the lead.
There with 55 orbital launches through the end of June, which amounted to a launch every 3.29 days or 79 hours. The total is more than half the 90 launches attempted in 2017. With approximately 42 missions scheduled for the last six months of the year, the total could reach 97. (more…)
The world’s launch providers have been extremely busy in the first quarter of 2018, with 31 orbital launches thus far. This is more than one third of the 90 launches conducted last year.
China leads the pack with 10 successful launches. The United States is close behind with a total of nine launches with one failure. The tenth American launch is scheduled for Monday afternoon from Florida.
SpaceX successfully launched 10 Iridium Next satellites aboard a Falcon 9 rocket from Vandenberg Air Force Base in California on Friday morning.
Iridium-NEXT satellites 41-50 were successfully deployed from the booster’s second stage about an hour after the launch at 7:13 a.m. PDT. It was the fifth batch of 10 Iridium-NEXT satellites that SpaceX has orbited using three different first stage boosters.
The world’s most powerful booster is set to make a flight test sometime in January. If all goes well, 27 first stage engines will power the new booster off Pad 39A at NASA’s Kennedy Space Center. The three first stage cores will peel off and land for later reuse while the second stage continues into space.
SpaceX had a banner year in 2017, launching a record 18 times and helping to propel the United States to the top of the global launch table with a perfect 29-0 record. The U.S. total made up 32.2 percent of 90 orbital launches worldwide, which was an increase over the 85 flights conducted in 2016.
The 29 American launches were a leap of seven over the 22 flights conducted the previous year. This is the highest number of American orbital launches since the 31 flights undertaken in 1999. However, that year the nation’s launch providers suffered four failures whereas they were perfect in 2017.
Russia successfully launched a Lotos electronic intelligence spy satellite aboard a Soyuz-2.1b booster on Saturday from the Plesetsk Cosmodrome.
The flight came four days after the failure of a similar Soyuz-2.1b launched from the Vostochny Cosmodrome. The launch from Plesetsk did not use the Fregat upper stage blamed for the failure on Tuesday.
Officials believe the Fregat upper stage was not properly programmed for a launch from Vostochny. The programming error caused the Fregat to send a Russian weather satellite and 18 secondary payloads into the Atlantic Ocean.
ULA says it scrubbed an early-morning launch of an Atlas V carrying the NROL-52 satellite due to weather violations. The launch has been rescheduled for Sunday, Oct. 15, at 3:28 a.m. EDT from Space Launch Complex-41 at Cape Canaveral Air Force Station. It was the third scrub of the flight due to weather constraints and the fourth scrub overall.
A Russian Soyuz rocket carrying a Russian Progress resupply ship blasted off from the Baikonur Cosmodrome on Saturday. The freighter will take about two days to reach the International Space Station. The launch comes two after a last-minute abort of the Soyuz booster.
On Friday, the European Sentinel 5 Precursor satellite was orbited by a Russian Rockot booster from the Plesestk Cosmodrome. The mission, a joint collaboration of the European Commission and European Space Agency, will measure greenhouse gases.
SpaceX successfully launched the SES 11 and EchoStar 105 communication satellites on Wednesday evening from NASA’s Kennedy Space Center in Florida. The first stage of the Falcon 9 rocket landed on an off-shore drone ship.
Meanwhile, the launch of Progress 68 resupply ship was scrubbed from Baikonur for an unknown reason. The launch of the Soyuz rocket has been rescheduled for no earlier than Saturday Oct. 14 at 4:46 am EDT (0846 GMT).
