MOSCOW: A piece of space junk flew at a distance of 1.8 km from the International Space Station (ISS), Russia’s State Space Corporation Roscosmos announced.
“According to the data of Russian specialists, an uncatalogued piece of space debris flew at a distance of 1.8 km from the International Space Station at around 4:15 p.m. Moscow time,” the statement says.
It was highly unlikely that the orbit paths of the orbital outpost and the space junk would intersect and, therefore, there was no need for the ISS to conduct an avoidance manoeuvre, the Russian space agency explained.
Roscosmos Chief Dmitry Rogozin said on Wednesday that the space object dubbed Unknown would pass by the orbital outpost at a distance of 4.8 km. He stressed that Roscosmos agreed with the US side only in the assessment of the near-miss distance.
“We do not confirm the threat and continue monitoring the situation,” he explained.
Roscosmos later specified that the minimum distance between the International Space Station and the piece of space junk that might fly close to it had narrowed to 1.5 km from its earlier predicted figure of 4.6 km.
The Russian space agency said earlier that the probability for the space debris to collide with the ISS was zero and no orbit adjustment of the station was required.
Head of the Information Analytical Center at the Central Research Institute of Machine-Building (TsNIIMash, part of the space agency Roscosmos) Igor Bakaras earlier said that Russia’s Automated Warning System of Hazardous Situations in near-Earth Space registered 220 space junk near-misses with the International Space Station in 2020.
The space station’s orbit had to be adjusted twice in 2020 to avoid a collision with space junk, he added.
VOSTOCHNY COSMODROME : A Soyuz-2.1b carrier rocket with the Fregat booster and 36 British OneWeb communications satellites blasted off from the Vostochny spaceport in Russia’s Far East.
The Fregat booster with the satellites successfully separated from the carrier rocket several minutes after the launch, Russia’s State Space Corporation Roscosmos announced in a live broadcast on its website.
The Soyuz-2.1b rocket lifted off from the Vostochny spaceport at 3:48 p.m. Moscow time. It will take the booster about four hours to orbit the satellites. The satellites will separate in several stages. As a result, the British company’s orbital constellation will grow to 254 satellites.
The first six OneWeb satellites were orbited by a Soyuz-ST carrier rocket from the Kourou spaceport in French Guiana on February 28, 2019. Another 34 satellites were delivered into outer space on February 7, 2020, and the same amount on March 21 from the Baikonur spaceport.
OneWeb satellites were launched from the Vostochny spaceport for the first time in December 2020. A total of 36 space vehicles were put into orbit. After that, OneWeb satellites were launched from the Vostochny spaceport on March 25, April 26 and May 28, 2021.
OneWeb’s renewed agreement with the French Arianespace that acts as the launch operator stipulates the lift-off of 16 Russian Soyuz carrier rockets from the Kourou, Vostochny and Baikonur spaceports in 2020-2022. Each launch allows orbiting 34-36 OneWeb satellites.
Russia has completed the deliveries of Sukhoi Su-35 generation 4++ fighter jets to China under a contract signed earlier, Russia’s Federal Service for Military and Technical Cooperation told TASS on Tuesday.
“In compliance with the contract, all the Su-35 planes have been delivered to the foreign customer,” the Federal Service said.
China has been the first foreign buyer of Russian Su-35 fighter aircraft. The contract worth about $2.5 billion on the deliveries of 24 fighter jets to China was signed in 2015. The contract also stipulates the delivery of ground equipment and reserve engines.
Indonesia is the second foreign buyer of Russian Su-35 fighter jets. Reports emerged in early 2018 that Russia had signed a contract with Indonesia on the delivery of 11 fighters. Under the contract, Russia is due to deliver the first fighter jets to Indonesia this year. The fulfillment of the Indonesian contract ran across some difficulties related to US sanctions but a TASS source in military and diplomatic circles said these difficulties “are not critical” and should not affect the deliveries of fighter jets.
The Su-35S generation 4++ supersonic fighter jet performed its debut flight on February 19, 2008. The fighter jet is a derivative of the Su-27 plane. The Su-35S weighs 19 tonnes, has a service ceiling of 20,000 meters, can develop a maximum speed of 2,500 km/h and has a crew of one pilot. The fighter jet’s armament includes a 30mm aircraft gun, up to 8 tonnes of the weapon payload (missiles and bombs of various types) on 12 underwing hardpoints. The Su-35S has been in service with the Russian Army since 2015.
Some components of the S-400 air defense system may be produced in Turkey under an agreement between Moscow and Ankara, Russian presidential spokesman Dmitry Peskov told the media on Thursday, when asked if President Vladimir Putin’s remark about the possibility Russia and Turkey might cooperate in developing military technologies implied joint production of S-400 systems.
“Comprehensive production of all S-400 components is not on the agenda and it is ruled out. It’s a cutting-edge weapon system. Joint production of some individual parts is possible, though,” he said, adding that it might be arranged in Turkish territory.
After talks with Turkish President Recep Tayyip Erdogan on April 8 Putin mentioned some promising prospects for military-technical cooperation, such as the export of military products to Turkey. Also, he speculated that Russia and Turkey “might well conduct joint research into and production of high-tech military technologies.”.
Russia needs to heavily upgrade its space industry and improve the sector’s management model, Russian President Vladimir Putin said at a Security Council meeting on Tuesday.
“It is obvious that it is necessary to fundamentally modernize the rocket and space industry, introduce the modern model of managing the production process, R&D work and learn to use the results of space activity in all the spheres of our life by a factor more efficiently,” the Russian leader stressed.
The issues of improving state policy in the sphere of space activity are extremely important, the Russian leader said. Leading positions in space exploration are essential for solving national development tasks, ensuring the country’s security, its technological and economic competitiveness, Putin noted.
The Russian president believes that Russia has broad experience in developing and manufacturing space rocketry, implementing flights and large-scale scientific programs in orbit. However, Russia needs constantly to build up this potential, Putin stressed.
The Russian leader drew attention to the need to involve the space industry’s potential for solving tasks in the sphere of telecommunications, communications, transport, medicine, housing and utilities. “Building up exports is a key area,” the Russian leader pointed out.
“In expert estimates, the world space market is worth $183 billion annually and is set to further expand in coming years and decades,” he said.
Putin urged the government, the agencies concerned and the Russian space agency Roscosmos to maximally use available competitive advantages instead of marking time.
The Russian leader said it was necessary to complete Roscosmos’s reorganization and start working towards specific results, solving obvious problems that impeded the space industry’s development.
“For example, the price and time parameters projected in drafting space projects frequently lack due substantiation and, as a result, the planned timeframe is shifted while budget expenses increase. This has happened many times in recent years,” the head of state said, calling for more active efforts to remove restraining factors.
