    TeLEOS-2 is a synthetic aperture radar satellite developed under a partnership between the Defence Science and Technology Agency (DSTA), representing the Government of Singapore and ST Engineering.

    After deployment of the satellite into the about 586 km orbit, it would be used to support the satellite imagery requirements of various agencies within the Government of Singapore. TeLEOS-2 carries a Synthetic Aperture Radar (SAR) payload. It would be used to provide all-weather day and night coverage and is capable of imaging at 1-metre full polarimetric resolution for Singapore.

    Lumelite-4 satellite is co-developed by the Institute for Infocomm Research and Satellite Technology and Research Centre of the National University of Singapore.

    It is an advanced 12U satellite developed for the technology demonstration of the High-Performance Space-borne VHF Data Exchange System (VDES). The satellite’s objective is to augment Singapore’s e-navigation maritime safety and benefit the global shipping community, ISRO said.

  • EU turns to Elon Musk to replace stalled French rocket

    EU turns to Elon Musk to replace stalled French rocket

    The European Commission wants to cut deals with private American space companies like Elon Musk’s SpaceX to launch cutting-edge European navigation satellites due to continued delays to Europe’s next generation Ariane rocket system.

    In a draft request to EU countries seen by POLITICO, the Commission is planning to ask for a green light to negotiate “an ad-hoc security agreement” with the U.S. for its rocket companies to “exceptionally launch Galileo satellites.”

    The Commission reckons only SpaceX’s Falcon 9 heavy launcher and United Launch Alliance’s Vulcan system are up to the job of sending the EU’s new geo-navigation Galileo satellites — which weigh around 700 kilograms each — into orbit.

    Seeking U.S. help to keep its flagship space program running puts a dent in the EU’s idea of strategic autonomy. Galileo is a point of pride for the EU, as it seeks to become less dependent on other regions for critical infrastructure, services and technology — a quest strongly backed by Paris.

    The EU is having to seek assistance to launch new versions of its navigation satellites because the Ariane 5 rocket, developed by France-based ArianeGroup and launched from France’s South American spaceport in French Guiana, is to be retired in the next months.

    The deployment of its replacement, Ariane 6, has been delayed; the new system is currently expected to carry out a maiden launch at the end of this year, with full commercial deployment starting next year.

    The alternative to the Ariane series would have been launching Galileo satellites with Russian-built Soyuz rockets, a version of which are also used at the French Guiana site. However, since Russia’s invasion of Ukraine, two Galileo launches using Soyuz rockets have been cancelled, prompting the search for alternatives.

    Galileo satellites beam highly accurate navigation and precise time data back to earth — and also provide a top secret encrypted service for use by government agencies. That means launches typically can only be carried out from EU territory under tight security rules.

    “In view of the security sensitive information … included in Galileo satellites, an ad-hoc legally binding security agreement with [the] U.S. is necessary, in order to protect the integrity of the satellites and the Galileo constellation,” said part of a draft proposal from the Commission seen by POLITICO.

    It will be up to EU countries to approve negotiations for an agreement, which would come under the umbrella of standing deals on the exchange of classified information, the proposal states.

    Capacity to launch satellites and humans into space independently of other powers has been a key part of French efforts to develop the concept of strategic autonomy for Europe.

    But the need to contract out launches of critical space infrastructure to private companies operating in the U.S. undermines the argument that Europe is able to manage its own alternative to the U.S. GPS, Russia’s Glonass and China’s BeiDou constellations.

    “Analyses are … ongoing to ascertain whether or not launching with an alternative launch service provider would be feasible,” said Commission spokesperson Sonya Gospodinova, adding that no decision has yet been taken. Assessments are being made on technical compatibility, launch site security and cost, she said.

    While SpaceX’s Falcon rocket is already operational, ULA only plans its first Vulcan mission in May.

    The Paris-based European Space Agency, which isn’t an EU institution but helps manage Galileo and runs the French Guiana spaceport, had already been looking at alternative launch options for satellites.

  • ISRO’s LVM3 rocket carrying 36 satellites blasts off from Sriharikota

    ISRO’s LVM3 rocket carrying 36 satellites blasts off from Sriharikota

    [ad_1]

    Sriharikota: ISRO’s heaviest rocket LVM3 carrying 36 satellites belonging to UK-based OneWeb Group lifted off from this space port on Sunday.

    The second dedicated mission for NewSpace India Ltd, the commercial arm of Indian Space Research Organisation is part of the agreement signed with Network Access Associates Ltd, United Kingdom (OneWeb Group Company) for launch of 72 satellites into Low-Earth orbits(LEO).

    The first set of 36 satellites of OneWeb Group company was launched on October 23, 2022 by ISRO.

    At the end of the 24.5 hour countdown, the 43.5 metre tall rocket blasted off at 9 am from the second launch pad here, about 135 km from Chennai.

    Bharti Enterprises is a major investor in OneWeb group, which is engaged in the implementation of the constellation of low earth satellites.

    It is a global communication network powered from space, enabling connectivity for governments and businesses.

    The launch was the 18th for OneWeb Group company while for ISRO, it would be the second mission in 2023 after the successful launch of SSLV/D2-EOS07 mission undertaken in February.

    With today’s mission, OneWeb would have 616 satellites in its fleet which would be more than enough to launch global services later this year.

    The mission marks OneWeb’s second satellite deployment from India, highlighting the collaboration between the United Kingdom and Indian space industries, OneWeb said.

    Across India, OneWeb would bring secured solutions not only to enterprises but also to towns, villages, municipalities and schools including the hardest to reach areas across the country, the company said.

    The first set of satellite separation (comprising four of the 36 satellites) is scheduled to take place around 20 minutes after lift-off. The remaining satellites are expected to be placed into the 450 km circular orbits in sometime.

    The satellites after being placed into the low-earth orbits would be divided among 12 planes at an altitude of about 1,200 km from Earth’s surface. Each plane would be separated in an altitude by 4 km to prevent inter-plane collision, ISRO said.

    This is the sixth flight of LVM3 which was earlier known as the Geosynchronous Satellite Launch Vehicle MkIII (GSLVMkIII) with a cryogenic upper stage. It had five consecutive missions including the Chandrayaan-2.

  • Satellite’s successful launch shows ISRO’s prowess in space sector: Andhra CM

    Satellite’s successful launch shows ISRO’s prowess in space sector: Andhra CM

    [ad_1]

    Amaravati: Andhra Pradesh Chief Minister YS Jagan Mohan Reddy on Friday said that the placement of three satellites successfully into their intended orbits showed the prowess of the Indian Space Research Organisation (ISRO).

    CM Jagan Reddy extended congratulations to the team of ISRO for the launch of SSLV-D2, propelling the nation’s space initiatives.

    “The mission of placing three satellites into the intended orbits shows the prowess of Indian Space acumen,” Chief Minister Jagan Mohan Reddy said and wished ISRO team and the youngsters associated with the project all success in future endeavours.

    The Small Satellite Launch Vehicle – SSLV-D2 has been successfully launched from Satish Dhawan Space Centre at Sriharikota in the morning and successfully placed three satellites EOS-07, Janus-1 and AzaadiSAT-2 into their 450 km circular orbit.

    “SLV-D2/EOS-07 Mission is accomplished successfully. SSLV-D2 placed EOS-07, Janus-1 and AzaadiSAT-2 into their intended orbits,” said ISRO.

    The launch has put ISRO’s an earth observation satellite EOS-07 and two co-passenger satellites Janus-1 and AzaadiSAT-2 into a 450 km circular orbit around the Earth.

    Soon after the launch, Mission Director, ISRO Vinoth said “Janus 1 satellite separated. SSLV D2 mission accomplished.”

    The new vehicle was developed to capture the emerging small and microsatellite commercial market.
    Speaking on the occasion, ISRO chief S Somanath said, “Congratulations to all three satellite teams for making the satellites as well as placing them in right orbit.

    We analysed the problems faced in SSLV-D1, identified corrective actions and implemented them at a very fast pace to ensure the vehicle becomes successful this time.”

    He said, “Today, after this launch, we are preparing to commence the launch campaign of PSLV-C55. This launch is for NSIL and will probably be launched by the end of March. So the launch campaign will commence today by placing the rocket at launch pedestal in a new facility.”

    According to ISRO, the second developmental flight of SSLV-D2 was scheduled at 09:18 hours IST from the first launch pad at SDSC SHAR in Sriharikota. SSLV-D2 is intended to inject the EOS-07, Janus-1 and AzaadiSAT-2 satellites into a 450 km circular orbit, in its 15-minute flight.

    EOS-07 is a 156.3 kg satellite designed, developed and realized by ISRO. New experiments include mm-Wave Humidity Sounder and Spectrum Monitoring Payload. Janus-1, a 10.2 kg satellite belongs to the US-based firm Antaris. It is configured with three solid propulsion stages and a velocity terminal module. It is a 34 m tall, 2 m diameter vehicle having a lift-off mass of 120 t.

    Meanwhile, the 8.7 kg satellite AzaadiSAT-2 is a combined effort of about 750 girl students across India guided by Chennai-based Space Kidz India.

    SSLV caters to the launch of up to 500 kg satellites to Low Earth Orbits on a ‘launch-on-demand’ basis.
    The space research body said it provides low-cost access to Space, offers low turn-around time and flexibility in accommodating multiple satellites, and demands minimal launch infrastructure.
    The first test flight of SSLV ended in partial failure on August 9, 2022.

  • NASA satellites are helping Turkey, Syria earthquake response

    NASA satellites are helping Turkey, Syria earthquake response

    [ad_1]

    Washington: After the massive earthquakes that struck southern Turkey and western Syria on February 6 and killed thousands, NASA on Saturday said it is working to share its aerial views and data from space to aid relief and recovery workers, as well as improve its ability to model and predict such events.

    Scenes collected before and after the earthquake were used by a team of scientists from the Earth Observatory of Singapore and NASA’s Jet Propulsion Laboratory in Southern California to create something called a damage proxy map for Turkey.

    These maps compare before and after radar images of a given event to see how the landscape has changed.

    “NASA’s hearts and minds are with those impacted by the earthquakes in Turkey and Syria,” said NASA Administrator Bill Nelson.

    “NASA is our eyes in the sky, and our teams of experts are working hard to provide valuable information from our Earth-observing fleet to first responders on the ground,” he added.

    One of NASA’s key capabilities is an expertise with synthetic aperture radar, or SAR.

    Viewing Earth in all weather conditions, day or night, SAR is used to measure how the ground moves and built landscape changes after this type of event.

    “We don’t know everyone who is using this information or how, but we are fortunate to have heard back from a few groups. For instance, the World Central Kitchen – which is providing food to those who’ve been displaced – have let us know they make use of it,” said Lori Schultz, NASA’s disaster coordinator for this earthquake.

    In addition to assessing damage, NASA scientists use space- and ground-based observations to improve the agency’s ability to understand related events that cascade from the original natural disaster.

    While not in use yet, NASA scientists are hoping to add a new tool to assess the aftermath of the quake.

    The Earth Surface Mineral Dust Source Investigation, or EMIT, instrument was launched to the International Space Station in July 2022.

    As part of its observations of the composition of material in Earth’s atmosphere, it can assess methane emissions.

    When passing over the earthquake site, measurements of increased or new emissions could point to events not otherwise easily spotted from space.

    As search and rescue efforts continued for a sixth straight day on Saturday to find more survivors, the number of people killed following the devastating earthquakes that struck Turkey and Syria on February 6 has reached at least 23,831.

  • India launched 353 foreign satellites since 2014: Govt

    India launched 353 foreign satellites since 2014: Govt

    [ad_1]

    New Delhi: India has launched 353 foreign satellites since 2014, earning the country foreign exchange, Union Minister Jitendra Singh said on Wednesday.

    He said India earned 187 million euros from European countries and 39 million dollars from the US by launching satellites since the Modi government came to power in 2014.

    Earlier, in reply to a question in Lok Sabha, Singh said in order to promote and encourage public-private-participation projects and start-ups, a central PSU called “NewSpace India Limited (NSIL)” has been established.

    He said a single-window nodal agency “Indian National Space Promotion and Authorization Centre (IN-SPACe)” has been established to promote non-government entities and to create an ecosystem for private companies in the space sector.

    Singh said 135 applications have been received by IN-SPACe from non-governmental entities and start-ups in the space sector.

    Responding to a question on start-ups in the sector, Singh said a new seed fund scheme has been approved by the IN-SPACe Board to provide initial financial assistance to Indian space start-ups.

    Singh said a revised FDI policy in the space sector to facilitate overseas investment in non-government enterprises and a national space policy are in the process of final approval.
